This file lists all changes made to the game driver in all glory detail.
See the file HISTORY for a user-oriented summary of all the changes.
30-May-2009 (LDMud Team) (3.3.719)
- Created snapshot.
29-May-2009 (Gnomi)
- (call_out.c) Preserve the order of call_out()s.
- (mudlib/deprecated/hash.c) Added sefuns md5() and sha1().
- (configure) Added a bunch of quotation marks.
28-May-2009 (Zesstra)
- Added sefun cat(), updated documentation of cat().
To reduce the workload of our users we supply implementations of
deprecated and removed efuns. This time: the deprecated efun cat().
(mudlib/deprecated/*)
- Removed a configure check for ancient gcc on AIX.
- Added checks to configure for the volatile keyword and VLAs.
- Check the compiler for support of -fwrapv and enable if supported (enables
a fully defined overflow/wrap behaviour of signed integers (#635).
- Support for using mmap() to get memory from the system (slaballoc):
sbrk() and brk() are obsoleted and some systems (like Darwin) don't have a
working implementation anymore. If sbrk/brk() are not usable, but mmap()
is available, use mmap() for mapping anonymous memory which we then use.
If mmap() is not available, use the old fallback (system malloc()).
Changed some precompiler checks for SBRK_OK, which should be
REPLACE_MALLOC. (#640)
(slaballoc.c, xalloc.c, configure.in)
- Support for using mmap() to get memory from the system (smalloc). (#640)
(smalloc.c)
- Removed amalloc/afree(), MALLOC_ALIGN and MEM_ALIGN.
Our amalloc() had errors and never worked as intended. As the driver does
not need more alignment than guaranteed by the allocators, amalloc() was
removed (see commit log for details).
(xalloc.c, slabmalloc.c, smalloc.c, sysmalloc.c, xptmalloc.c)
27-May-2009 (Gnomi)
- (ed.c, comm.c) Put ed sessions into the input_to list of interactive
objects, so now they have a common noecho and prompt handling. (Bug #522)
- (call_out.c, backend.c) Corrected the timing of call_outs from inside
a heartbeat. (Bug #375)
- (comm.c) Allow sending \0 with binary_message(). (Bug #71)
- (comm.c) Enable IAC quoting by default, allow enabling '\0'
and disabling '\n' in connection charsets.
26-May-2009 (Fuchur)
- (ed.c) Fix bogus reference increment in clear_ed_buffer_refs()
26-May-2009 (Zesstra)
- (func_spec) Marked efun cat() as deprecated. (#637)
19-May-2009 (Gnomi)
- (prolang.y, interpret.c) Corrected the handling of implicit context
variables in nested inline closures and allowed the initializers
of explicit context variables to reference other explicit context
variables. (Bug #631)
- (main.c, comm.c) Set the close-on-exec-flag on open file descriptors,
so they are not passed to erq. (Bug #629)
- (pkg-tls.h, pkg-openssl.c, pkg-gnutls.c, main.c, configure)
Allow TLS to be deactivated per default or command line. (Bug #479)
18-May-2009 (Gnomi)
- (pkg-xml2.c, arraylist.c, configure) Added support for XML parsing
using libxml2. (Bug #538, thanks, Bardioc!)
- (interpret.c) Ignore any arguments passed to a variable closure
instead of throwing an error. (Bug #612)
12-May-2009 (Fuchur)
- (object.c) compile fix for !USE_NEW_INLINES
- (prolang.y) forbid accessing closure arguments from within the
closure's context.
- (prolang.y) Fix infinite loop when redefining a closure argument
in its closure's context.
11-May-2009 (Gnomi)
- (sprintf.c) Don't rely on overflow, as gcc optimizes away overflow checks.
10-May-2009 (Zesstra)
- (smalloc.c, slaballoc.) Replaced SINT by GRANULARITY
The define SINT was ill-named. All occurences were renamed to GRANULARITY
which describes the semantics of the define much better and it is now
defined as being sizeof(word_t).
Additionally, MEM_ALIGN is now defined as being the same as GRANULARITY.
- (xalloc.c) Replaced define by enum.
The defines for the header fields of memory blocks were replaced by an enum.
Additionally a comment about word_t is added.
- (xalloc.c) Fixed syntactial errors in pre-compiler statements.
Because MEM_ALIGN is now a sizeof() expression, it can't be used in
conditional compilation. Replaced them by real if() (which are eliminated
by the compiler because their expression is constant).
- (object.c) Fixed buffer overflow in save_svalue() (#634)
save_svalue() used PRIx16 to print the exponent of a float. Unfortunately,
on some systems PRIx16 is %x, although int16_t is a short. This causes a
signed conversion (which keeps the value) and then 0xffffffff is written.
Even if the buffer is large enough, upon restore with SCNx16 (%hx) a wrong
value would be restored. *args*
Additionally all sprintf(), which write into number_buffer were replaced
by snprintf().
06-May-2009 (Zesstra)
- (hosts/) The hosts/ directory was removed.
Removed the whole hosts/ directory because it wasn't maintained for a long
time and most of the systems were anyway dead for a long time (#625).
This removed --enable-use-system-crypt as well (#624).
- Removed checks and special code for OS2 and __EMX__.
- Removed check for MSDOS.
- Removed checks and special code for __BEOS__.
- Removed checks and special code for AMIGA.
- Removed checks and work-arounds for very old gcc compilers (2.x, <3.2).
- Removed checks and special code for SunOS4 (The last release of SunOS4
was in 1994.)
- Removed checks and special code for Ultrix.
- Removed MSDOS filesystem semantics (Checks for MSDOS_FS and special
behaviour (e.g. \\ as path separator).
- (prolang.y) Another fix in insert_pop_value().
In case of F_NUMBER was the operation itself not taken into account.
Replaced hard-coded numbers by the appropriate sizeof() in all other cases
as well.
05-May-2009 (Zesstra)
- (prolang.y)
Fix inconsistent F_NUMBER generation (#628).
The compiler generates F_NUMBER at more than one places. ins_number()
only writes a int32 into the bytecode, all the other places write a p_int,
which interpret.c expects.
The patch adds ins_p_int(), upd_p_int() and read_p_int().
ins_number() now calls ins_p_int() upon generating the F_NUMBER instruction.
Additionally upon storing a number (L_NUMBER) and in the unary '-'
upd_p_int() is called instead of a direct memcpy(). (memcpy() is a bit
faster, but I think it is much more risky to forget a place to change...)
- (prolang.y) Fixed insert_pop_value().
insert_pop_value() removes the last value from the stack. If possible, it
patches the code to prevent that value from being computed at all (by
removing the last expression). Unfortunately the function assumed that all
operations have no data following in the bytecode. This patches changes it
and enabled optimization/removal of operations with data.
05-May-2009 (Gnomi)
- (lex.c, efuns.c) Improved numeric overflow detection. (Bug #630)
- (pkg-gnutls.c) Don't abort on EINTR or EWOULDBLOCK.
04-May-2009 (Zesstra)
- (efuns.c, efuns.h, func_spec, string_spec, doc/, mudlib/)
Added new efun: configure_driver() and documentation.
configure_driver() will configure variuous aspects of the driver at run-time.
The first settings available is now the soft and hard memory limits.
- (smalloc.c, slaballoc.c, sysmalloc.c, xptmalloc.c)
Added soft and hard memory limits in output of then 'malloc' command.
- (object.c)
Fix for float corruption in restore_svalue().
We use 32 bit mantissas and 16 bit exponents for our floats. Ensure to
write and read fixed-width types in save_svalue() and restore_svalue().
Fixes #627, where restore_svalue() interpreted the 16bit integer for the
exponent as 32bit integer, resulting in data corruption if the exponent
was negative.
- (svalue.h)
The defines READ_DOUBLE, SPLIT_DOUBLe and STORE_DOUBLE were exchanged
by static inline functions.
STORE_DOUBLE_USED is not needed anymore and defined empty.
Additionally, SPLIT_DOUBLE returns now the mantissa as p_int instead of long.
- (interpret.c)
The compiler stores float literals with PUT_INT32 and PUT_SHORT. Reading
them from the bytecode was done by memcpy(). Some conditional compilation
was required to read the correct datatypes. This patch implements an old
TODO and makes F_FLOAT use the LOAD_INT32 and LOAD_SHORT macros from
bytecode.h.
19-Apr-2009 (Gnomi)
- (pkg-tls.c) Set this_interactive() when executing the callback
after handshaking and print the prompt afterwards, so it looks the
same as a normal logon() call.
- (closure.c, interpret.c) New opcodes F_CALL_CLOSURE and F_POP_SECOND
for calling more complicated closures like lambda, inherited lfun
and context closures from within a lambda closure. (Bug #613)
16-Apr-2009 (Gnomi)
- (comm.c, interpret.c, doc/) Made the maximum write buffer size
configurable per interactive via a new efun configure_interactive.
New optional driver hook H_MSG_DISCARDED to inform the master about
discarded messages and send a custom error message to the interactive.
Already compressed packages wont be discarded (Bug #297).
15-Apr-2009 (Gnomi)
- (pkg-gnutls.c) Support for older versions of libgnutls.
- (port.h, object.c)
Savefiles are written in binary mode, if the host system supports any
such notion (O_BINARY exists). Additionally, they are read as binary
as well, if it is supported. (Note: POSIX conforming systems do not
distinguish between 'text' and 'binary' modes, this is only relevant
to Cygwin.)
14-Apr-2009 (Gnomi)
- (doc/driver/predefined) Corrected description of __PATH__(n).
- (mk-patchlevel.h) Call version.sh in the current directory.
- (interpret.c) The size of big switch structures was miscalculated
on LP64 platforms. (t-0000622.c)
12-Apr-2009 (Gnomi)
- (efuns.c, pkg-openssl.c, pkg-gcrypt.c) Moved hash() and hmac()
from pkg-openssl.c to efuns.c and implemented them also using
libgcrypt or the internal MD5 and SHA1 routines (bug #52).
- (efuns.c) fixed a memory leak in hash() and hmac().
- (efuns.c) hash() now costs 10 ticks per iteration.
- (efuns.c) sha1() calculated wrong hash values with multiple
interations.
- (doc/efun) Marked md5() and sha1() as obsoleted by hash().
- (pkg-openssl.c) Don't set a just queried client CA again. (Bug #583)
10-Apr-2009 (Gnomi)
- (pkg-gnutls.c) Implemented tls_refresh_certs and tls_check_certificate
with GnuTLS.
09-Apr-2009 (Gnomi)
- (interpret.c) Wrongly calculated the jump offset of the default
label in big switches due to a sign error (maybe #622).
- (exec.h) Another value for NAME_CROSS_DEFINED so that it doesn't
conflict with FUNSTART_MASK (large programs could hit that bit).
08-Apr-2009 (Gnomi)
- (pkg-tls.c) Set command_giver when executing the callback
after handshaking (Bug #499).
07-Apr-2009 (Gnomi)
- (pkg-tls.h) Corrected the definition of tls_check_certificate.
- (pkg-gnutls.h, pkg-openssl.h) Forgot an include.
- (main.c) Removed a superfluous pointer dereference.
21-Mar 2009 (Gnomi)
- (pkg-tls.c, pkg-openssl.c, pkg-gnutls.c) Separated code for GnuTLS
and OpenSSL.
15-Mar-2009 (Fuchur)
- (test/inc/deep_eq.inc)
Implement deep equality for the testsuite.
- (test/t-efuns.c)
Add a few tests for map().
- (array.c, strfuns.c, structs.c, efuns.c, doc/efun[.de]/map[.de])
Implement map(*, mapping, idx). (#367)
12-Mar 2009 (Zesstra)
- (slaballoc.c, smalloc.c)
Fixed a bug in esbrk() during memory allocation, where SINT
(sizeof(word_t)) was not taken into account in the calculation of a block
size, leading to crashes afterwards. (#611)
- (efuns.c)
Fixed an off-by-one buffer overflow in v_sha1(). Actually removed the \0
written after the buffer, because it was not needed.
10-Mar 2009 (Zesstra)
- (pkg-idna.c)
Fixed the evaluation of the arguments of f_idna_stringprop() and removed a
memory leak, because the argument string was not free'd. Additionally
avoided to put a return value on the stack in case of an error (#498)
03-Mar-2009 (Zesstra)
- (actions.c, configure.in, config.h.in, lex.c)
Made the maximum length of commands configurable.
COMMAND_FOR_OBJECT_BUFSIZE was renamed to MAX_COMMAND_LENGTH and
made configurable at compile time via the --max-command-length,
defaulting to 1000.
Added a permanent define __MAX_COMMAND_LENGTH__
28-Feb-2009 (Zesstra)
- (xalloc.c|h, smalloc.c, main.c, lex.c, slaballoc.c, backend.c,
string_spec, mudlib/sys/rtlimits.h, src/settings*, doc/master/)
Renamed --max-malloced to --hard-malloc-limit and MAX_MALLOCED to
HARD_MALLOC_LIMIT_DEFAULT and changed the mud configurations.
Introduced a --soft-malloc-limit/SOFT_MALLOC_LIMIT_DEFAULT
Added set_* and get_memory_limit() and related constants for managing the
memory limits
Added check_for_soft_malloc_limit() to check the soft memory limit
Added notify_lowmemory_condition() to call low_memory() in the mudlib master
Added calls to notify_lowmemory_condition() and
check_for_soft_malloc_limit() in the ba ckend cycle
Added documentation for new memory limit and low_memory().
27-Feb-2009 (Fuchur)
- (settings/default)
Sync options with configure.
- (autoconf/configure.in)
Don't replace unspecified defaults by 'no' anymore.
Fix some quoting issues.
Add help messages for all custom options.
Remove a few unused options.
15-Feb-2009 (Zesstra)
- (port.c)
Check results of gmtime() and localtime() and return NULL, if NULL is
returned.
- (efuns.c)
Check results of gmtime(), localtime(), time_fstring() and utime_string()
for being NULL and raise a runtime error. (#587)
- (test/inc/testarry.inc, test/t-mantis.c)
Added tests for the efuns affected by bug #587.
Added an test flag TF_DONTCHECKERROR for tests which must not crash the
driver but may cause a runtime error or not.
31-Jan-2009 (Fuchur)
- (test/run.sh, test/t-0000604.sh)
Add Test for #604

28-Jan-2009 (Gnomi)
- (backend.c)
!-escaped commands are treated specially even
if the player object doesn't have an environment.
- (comm.c)
Correctly detect if input_to() was called more than once
in the same execution thread (Bug #535).
27-Jan-2009 (Gnomi)
- (xalloc.c)
realloc() should also consider the xalloc overhead, when
assessing the available space.
- (main.c)
Corrected --longhelp output of TLS options.
- (comm.c, configure)
Removed support for write threads.
18-Jan-2009 (Zesstra)

- (efuns.c)
Relaxed syntax check in v_trim() to allow a 0 as <ch> for trimming
"\0" (#473)
17-Jan-2009 (Fuchur)
- (efuns.c, func_spec, mudlib/sys/debug_info.h, doc/efun/debug_info,
doc/efun.de/debug_info.de)
use debug_info instead of new get_eval_number() efun.
- (efuns.c, func_spec, interpret.c, interpret.h, doc/efuns/get_eval_number,
doc/efuns.de/get_eval_number.de)
add get_eval_number efun.
- (backend.c, comm.c, interpret.c, object.c)
call mark_(start|end)_evaluation() in various places (#476)
- (prolang.y)
check return value of verify_declared() - fixes a crash in t-language
17-Jan-2009 (Gnomi)
- (object.c)
Save_object without a filename removed one too many elements
from the stack. (Bug #595)
16-Jan-2009 (Zesstra)
- (config.h.in, lex.c)
Enforce the possible value range for ITABLE_SIZE (256 - SHRT_MAX/32768).
Fixes issues of not finding identifiers in the table if the table is to
large. (#558)
Updated documentation in config.h.in to reflect this.
Corrected the manpages for read_file(). (#592)
14-Jan-2009 (Gnomi)
- (comm.c, pkg-mccp.c, configure)
Use of write buffers without the need for threads.
- (object.c)
Made restore_value reentrant. (Bug #548)
- (prolang.y)
Removed useless code.
14-Jan-2009 (Zesstra)
- (doc/driver/limitations)
Started to assemble a list of non-configurable limits - to be extended...
- (exec.h, object.c, closure.c, interpret.c)
Changed some code defines from exec.h to static functions and
constants to an enum.
Introducing a properly typed CROSSDEF_NAME_OFFSET() solves crash on LP64
platforms in functionlist(). (#559)
Renamed SEARCH_FUNCTION_INHERIT to search_function_inherit and return the
pointer to the inherit structure.
- (smalloc.c)
Fixed some warnings about wrong format specifiers reported by Bardioc.
13-Jan-2009 (Zesstra)
- (simulate.c)
Reallowed empty object names (/.c) (#525)
12-Jan-2009 (Lars Duening) (3.3.718)
- Created snapshot.
06 Jan 2009 (Fuchur)
- (util/xerq/erq.c, util/xerq/defs.h)
Remove dependency on the driver's random number generator - the
libc one should serve us just fine.
04-Jan 2009 (Zesstra)
- (interpret.c, interpret.h)
Changed ASSIGN_EVAL_COST to a static inline function assign_eval_cost_inl()
and use it consistently in interpret.c.
Changed MAX_SHIFT to a static const.
- (mstrings.h, mstrings.c, strfuns.c)
Changed some code defines to static inline functions.
Renamed the variables mstr_tabled and mstr_untabled to mstr_tabled_count
and mstr_untabled_count. (They had the same name as the old defines which
are now functions).
Removed unused and now superfluous ref_mstring_safe, mstring_ref(),
deref_mstring_safe, mstring_deref(), because ref_mstring() and
deref_mstring() can now handle arguments with side-effects.
Added some casts to remove the const from const arguments when passing them
off to get_txt(). (Don't worry, it is only cosmetic and temporary.)
- (random.h, random.c, main.c, autoconf/configure.in, config.h.in, efuns.c,
random/*)
Exchanged the Mersenne Twister (pseudo random number generator) by the
SIMD-oriented Fast Mersenne Twister (SFMT) to support random numbers up
to 2^63-1 on 64 bit platforms:
http://www.math.sci.hiroshima-u.ac.jp/~m-mat/MT/SFMT/
Additionally, the period length can be configured now. The SFMT
faciliates a better equidistribution and a faster recovery from a
0-excess state as well. (Bug #527)
Added the possibility to seed the PRNG from arbitrary files or devices by
using the commandline option --randomdevice. The default device is
/dev/urandom. If that is not readable, the driver falls back to seed the
PRNG with the system time.
03-Jan 2009 (Zesstra)
- (efuns.c, efuns.h, func_spec)
Extended present_clone() to optionally search for the <n>th object in the
environment.
- (port.h)
Cleaned up handling of gcc attributes (Assumption: gcc < 3 are out of use
now), added __attribute__ define which evaluates to nothing if gcc is
not used.
- (make_func.y)
Added NORETURN attribute to yyerror() and fatal()
Changed fatal() from int to void.
- (closure.c, interpret.c, simulate.h )
Added NORETURN attribute to lambda_cerror(), lambda_cerrorl(),
stack_overflow(), throw_error(),
- (port.h, main.h, comm.c, strfuns.h, closure.c)
Added the format attributes to: time_fstring(), strbuf_addf(),
vdebug_message(), comm_fatal(), lambda_cerror(), lambda_cerrorl()
- (xalloc.h)
Added the warn_unused_result attribute to xalloc_traced(),
rexalloc_traced(), pxalloc_traced(), prexalloc_traced().
- (mregex.c, mstrings.c, simulate.c)
Fixed some wrong format specifiers which gcc found after using the format
attribute on strbuf_addf().
30-Dec 2008 (Zesstra)
- (array.h, comm.c, smalloc.c, slaballoc.c, xptmalloc.c, xalloc.c,
sprintf.c)
Changed some code defines and pre-compiler constants to static inline
functions and enums (partially from Largo, thanks!)
26-Dec 2008 (Zesstra)
- (object.c)
Fixes a forgotten increment of a ref count in f_rename_object().
24-Dec 2008 (Gnomi)
- (ed.c)
The reference count of the filename and the exit function
wasn't cleared in a GC. (Bug #398)
- (prolang.y)
Switch now explicitly expects case/default statements in the switch
block and puts the non-case statements afterwards into their own
block scope. (Bug #584)
15-Dec 2008 (Zesstra)
- (object.c)
Fixed potential crashes in rename_object() and replace_program() due to
stack overflows. (Bug #581)
14-Dec 2008 (Gnomi)
- (src/interpret.c, src/autoconf/*)
Added option to show the evaluation costs in the stacktrace.
- (src/pkg-iksemel.c, many files)
Added support for XML parsing with iksemel. (Bug #538, thanks, Bardioc!)
(Zesstra)
- (efuns.c)
Fixed potential crashes due to stack overflows in process_string(),
regexplode(), regexp() and present_clone(). (Bug #578)
- (interpret.h, interpret.c, efuns.c, mudlib/sys/debug_info.h,
doc/efun/debug_info, doc/efuns.de/debug_info.de)
Added control_stack_depth() to determine the number of frames on the
control stack and added flag DIT_CURRENT_DEPTH to
debug_info(DINFO_TRACE,...).
- (interpret.c)
Replaced call to exit() by a call to fatal() in asster_master_ob_loaded()
to allow core dumpes to be written in cases when the master object could
not be loaded and there is no destructed master as well. (Bug #570).
- (simulate.c)
Fixed potential crash due to stack overflow in load_object(). (Bug #580).
13-Dec 2008 (Zesstra)
- (pkg-mysql.c)
Allocate temporary memory for the temporary string in f_db_conv_string()
on the heap, because the string is user supplied and calling the
function with a large string may cause a crash due to stack overflow.
(Bug #582)
- (efuns.c, strfuns.c)
Corrected format specifiers in errorf() calls.
12-Dec 2008 (Zesstra)
- (port.h, port.c, efuns.h, efuns.c, func_spec, gcollect.c)
added mkime(), an efun which converts a date/time information as
returned by local_time() to a unix timestamp (integer value).
added strftime(), an efun which converts a timestamp to a formatted
string using a format string with a variety of format specifiers.
changed caching behavious for ctime(): cache is now in the efun, not in
port.c which spares the driver to search for the shared string and
saves about 85% of execution time in case of cache hits. Removed
caching in case of millisecond precision as cache hits are rather
unlikely.
Added handlers for the garbage collection which take care of the cache
for ctime().
- (main.c)
use also locale defined in LC_TIME.
04-Oct 2008 (Zesstra)
- (object.c)
Allocate memory for the filename in f_save_object() and f_restore_object()
on the heap instead of the stack. Use the generic error handler in
save_object() and the already existing one in restore_object() to free the
buffer in case of errors. Minor changes in error handling in
f_restore_object() by pushing the handler earlier onto the stack and using
it more often. Fixes crash with large filenames. (Bug #576)
- (comm.c)
Allocate memory for temporary buffers in send_erq() and send_udp() on the
heap and not on the stack. Fixes crashes with large arguments. (Bug #577)
26-Sep 2008 (Zesstra)
- (interpret.c, interpret.h)
Changed return type of push_error_handler() to svalue_t *.
Added a simple generic error handler structure for holding a single
buffer, an error handling function for freeing the buffer and a function
for allocating memory on the heap and simultaneously pushing the
corresponding error handler onto the value stack.
- (efuns.c)
removed unneeded cast.
- (efuns.c, pkg-sqlite.c)
Used new return value of push_error_handler().
- (backend.c)
added missing initializers to some statistic_t variables.
- (strfuns.c)
x_filter_string():
Removed crash in efun filter() due to stack overflow in case of very
large strings. (Bug #575)
Don't return a 0 as result if memory for the result could not be
allocated due to an out-of-memory condition.
21-Sep 2008 (Zesstra)
- (actions.c)
f_execute_command(): added length of command to error message 'command too
long'
Corrected format specifiers
- (comm.c)
Corrected format specifiers
interactive_cleanup(): removed variable e
add_message(): fixed a potential crash due to a buffer overflow on the
stack using vsnprint() instead of vsprintf() (and spared the client a
comm_fatal()).
f_binary_message(): replaced a fatal() by an errorf() if a string could
not be allocated. Replaced the error message text as well, because that
is not a stack overflow (memory for the string is allocated on heap).
- (xalloc.h)
Corrected format specifiers.
- (object.c)
Corrected format specifiers, removed unneeded casts.
free_prog(): added refcount, program address and program name to message
for fatal() in case of negativ refcounts
v_function_exists(): changed flags to p_int.
save_array(), register_array(), register_mapping_filter(): changed i to
p_int
restore_svalue(): removed variable tmp while restoring a float.
- (efuns.c, mapping.c, prolang.y, simulate.c, structs.c, object.c, dumpstat.c)
Corrected format specifiers
- (interpret.c, heartbeat.c, simulate.c, call_out.c, comm.c, actions.c,
backend.c)
secure_call_lambda(), apply_master_ob(), secure_apply_ob(),
push_error_context(), errorf(), call_heart_beat(), call_out(),
replace_program_lambda_adjust(), call_function_interactive(),
execute_command(), process_objects():
take the address for rt_context from the rt member of the struct
error_recovery_info, not from the beginning of the struct. Removes
compiler warning "dereferencing type-punned pointer will break
strict-aliasing rules".
- (structs.c)
struct_t_unique_name(): sprintf -> snprintf
- (dumpstat.c)
dumpstat(): length of buffer given to strftime() was one too short.
19-Sep 2008 (Zesstra)
- (slaballoc.c)
Changed malloc_increment_size_calls, malloc_increment_size_success,
malloc_increment_size_total, num_avl_nodes to 'unsigned long' instead of
'long', they were anyway already printed as unsigned.
check_free_block(): added some details to an error message.
Added missing initializers to INIT_SLABENTRY, dummy and dummy2
mem_dump_extdata(): changed i to unsigned int (removed a warning
concerning comparison between signed and unsigned types).
- (interpret.c, lex.c)
Corrected two format specifier.
18-Sep 2008 (Zesstra)
- (prolang.y)
add_string_constant(): Added size to be allocated to an error message
Corrected a bunch of format specifiers
Added a missing line break in an error message in add_lvalue_code()
epilog(): changed size from int to p_int.
Changed some comparisons between signed and unsigned types in (lines
12229, 12322, 12935).
- (lex.c)
parse_numeric_escape(): Removed a comparison of unsigned long < 0 which is
never true and in this case not needed.
- (i-eval_cost.h)
add_eval_cost_n(): changed a comparison between signed and unsigned types
17-Sep-2008 (Zesstra)
- (simulate.c)
Corrected format specifiers, removed not needed casts, corrected some
casts.
Changed int to p_int in extract_limits(), added range check in
v_limited() and v_set_limits().
- (ptrtable.c)
find_add_pointer(): p_uint is the better choice for converting a pointer
16-Sep-2008 (Zesstra)
- (port.c)
Corrected 3 strftime() calls, the given buffer length was one smaller than
necessary.
Corrected a format specifier for an mp_int.
- (ptrtable.c)
Changed mp_int in find_add_pointer() to p_int because it stores anyway a
void*
Correct two format specifiers.
- (swap.c)
Corrected some format specifiers.
Increased field width for the numbers in 'status swap' a bit.
- (strfuns.c, lex.c)
Corrected some format specifiers, changed/removed some unneccessary casts.
15-Sep-2008 (Zesstra)
- (mapping.c)
corrected a lot of format specifiers
changed a bunch of int which are assigned a p_int to p_int (f_m_values(),
add_to_mapping_filter(), resize_mapping(), map_intersect(),
v_walk_mapping, x_filter_mapping(), x_map_mapping(), f_m_entry(),
f_unmkmapping(), _free_mapping(), check_map_for_destr(),
add_mapping(), compact_mapping(), struct set_mapping_user_locals,
set_mapping_user_filter(), set_mapping_user(), v_m_add(),
map_intersect_filter(), map_intersect(), v_mkmapping(),
f_m_reallocate(), f_widthof().
- (i-svalue_cmp.h)
changed d in svalue_cmp() to p_int instead of int.
14-Sep-2008 (Zesstra)
- (interpret.c)
Moved duplicate code for calculating the caller stack depth in a small
static function which will be inlined anyway.
13-Sep-2008 (Zesstra)
- (interpret.c)
Changed format specifiers for mp_int to PRI*MPINT and for p_int to
PRI*PINT and changed some specifiers to the native datatype of the
variable and removed the casts.
Corrected some unchecked assignments of (m)p_(u)int to int by using the
driver type instead of int or adding range checks before the
assignments. Changed some longs to p_int as well.
Added some precompiler sanity checks for MAX_TRACE, SIZEOF_STACK,
TOTAL_TRACE_LENGTH and CACHE_SIZE which have to fit into int.
get_arg() used a static buffer with length of 10 but writes a long
with %ld. Increased buffer length to 12 and used snprintf()
instead of sprintf().
get_line_number_if_any(): changed calculation of pointers to the beginning
of lambdas to use the more portable offsetof() and to use (PTRTYPE)
instead of (char*) and (unsigned long) casts for the pointers.
- (port.h)
Added check for pre-defined PRId32 to port.h for the (u)int32 type. If it
is not defined, define our own.
- (closure.h)
Include <stddef.h> which defines offsetof() in case it is not a compiler
builtin (uses by LAMBDA_VALUE_OFFSET).
- (doc/efun.de/call_other.de)
Rephrased misleading sentence about __LPC_ARRAY_CALLS__.
07-Sep-2008 (Zesstra)
- (closure.c, efuns.c)
Changed format specifiers for mp_int to PRI*MPINT and for p_int to
PRI*PINT and changed some specifiers to the native datatype of the
variable and removed the casts. Corrected some format specifiers which
were signed but the argument were unsigned.
- (efuns.c) Corrected typo in error message in v_sha1() which reported
itself as md5().
06-Sep-2008 (Zesstra)
- (lex.c, object.h, swap.c)
Changed format specifiers for mp_int to PRI*MPINT and for p_int to
PRI*PINT and removed some casts to long and used the correct format
specifiers for the actual datatype (e.g z for size_t).
- (sprintf.c)
changed argument num of num_add() to p_int.
inserted the correct length modifier for the p_int type into the format
string for the system sprintf() call. (#528)
10-Aug-2008 (Lars Duening) (3.3.717)
- Created snapshot.
10-Aug-2008 (Lars Duening) (3.3.716)
- Created snapshot.
10-Aug-2008 (Lars)
- The 3.3 branch is now considered stable.
08-Aug-2008 (Zesstra)
- (settings/morgengrauen) Updated file to include the settings currently
used in MorgenGrauen.
06-Aug-2008 (Gnomi)
- (files.c) Rewrote copy/move_file due to copyright issues.
26-Jul-2008 (Fuchur)
- (object.c)
remove tell_object_str(), and use tell_object() (#471)
use FMT_STRING in tell_object(), to support \0 characters (#472)
19-Jul-2008 (Zesstra)
- (array.c, backend.c, comm.c, dumpstat.c, interpret.c, mapping.c, lex.c)
Changed format specifiers for mp_int to PRI*MPINT and some for p_int to
PRI*PINT.
18-Jul-2008 (Zesstra)
- (autoconf/configure.in)
Removed check for values.h from configure.in and not used HAVE_VALUES from
port.h - obsoleted by limits+float.h (was TODO)
Removed self-written check for ANSI-C89 compliant compiler and used
AC_PROG_CC_STDC.
Removed self-written checks for uint32_t, ssize_t, size_t, off_t, long
long and added the corresponding autoconf macros
Removed obsolete AC_HEADER_STDC
Added checks for C99 datatypes: (u)int8_t, (u)int16_t, (u)int32_t,
(u)int64_t, (u)inptr_t, (u)intmax_t.
Added size checks for intptr_t, intmax_t, long long
Added some checks for compiler charactestics: stringenize operator in
preprocessor, typeof. (check for restrict due to problems with
mk_func.c still disabled)
Added header check for stdbool.h
Changed obsolete AC_CONFIG_HEADER to AC_CONFIG_HEADERS
- (port.h)
Fixed PHINT_MIN, PHINT_MAX and PHUINT_MAX in port.h. SIZEOF_CHAR_P ==
SIZEOF_SHORT * 2 they were defined to SHORT_MAX, SHORT_MIN, USHORT_MAX,
which should be SHRT_MIN, SHRT_MAX, USHRT_MAX.
Fixed selection of ph_int (short is not guaranteed to be 2 bytes)
Use inttypes.h and stdint.h if available.
Use stdbool.h and _Bool for our own Bool if available.
Removed own typedef for ssize_t as autoconf will provide is with a
suitable ssize_t if the standard headers don't have one, which is
anyway very unlikely.
Added defines for the right format specifiers for sprintf(), sscanf()
because we should discontinue to use hard-coded ones when working with
p_(u)int, mp_(u)int and ph_(u)int.
17-Jul-2008 (Gnomi)
- (comm, interpret, simulate.c) Added flag to set_noecho and secure_apply
to indicate external events (Bug #534).
- (interpret.c, string_spec) Removed the 'closures was bound to
destructed object' error message and clarified the F_UNDEF error
message (Bug #523).
16-Jul-2008 (Zesstra)
- (comm.c, autoconf/configure.in, config.h.in)
MAX_OUTCONN is now configurable with an configure switch
(--with-max_net_connects), closes Bug #486.
- (object.c) tell_room() sends message to the given environment itself as
well, if it is marked interactive. Closes Bug #505.
- (xptmalloc.c)
use clib_alloc_stat only if REPLACE_MALLOC is set and define
REPLACE_MALLOC if SBRK_OK is defined.
- (driver.h)
SBRK_OK is enforced if ptmalloc is used as memory allocator. ptmalloc has
no problem with pthreads and does not work without REPLACE_MALLOC right
now.
12-Jul-2008 (Zesstra)
- (interpret.h) removed duplicate and inconsistent prototype for
last_instructions and moved prototype for f_last_instructions() into the
#ifdef TRACE_CODE block.
11-Jul-2008 (Gnomi)
- (files.c) write_file doesn't raise an error if the flag is set
and the file doesn't exist (Bug #512).
10-Jul-2008 (Fuchur & Gnomi)
- (prolang.y) Incomplete variable clearance after an inner block
(Bug #537).
10-Jul-2008 (Gnomi)
- (pkg-sqlite.c, interpret.c, interpret.h) SQLite pragma statements
are now possible but privileged.
- (mstrings.c) mstr_n_str() now finds an empty string at the end
of an input string (Bug #536).
09-Jul-2008 (Fuchur)
- (object.c) Use xalloc instead of alloca for allocating the parse buffer
in f_restore_value(). (Bug #532)
07-Jul-2008 (Zesstra)
- (mregex.c, pkg-pcre.h, config.h.in, autoconf/configure.in)
Introduced the compile-time constant LD_PCRE_RECURSION_LIMIT and code
for limiting the amount of recursions in the PCRE package. The purpose
is to prevent crashes from stack overflows, as the PCRE package may
recurse heavily. Default is 3000 recursions for systems with about 8MB
stack size per process. (Bug #524)
04-Jul-2008 (Zesstra)
- (test/t-0000524.c) Added a test for Bug #524
03-Jul-2008 (Gnomi)
- (test/*) Added a testsuite and included existing test cases therein.
- (test/t-0000532.c) Added a simple test for Bug #532 (Zesstra)
01-Jul-2008 (Gnomi)
- (comm.c) input_to could leak its parameters when it failed (Bug #486).
- (comm.c) Corrected the argument number in input_to error messages.
- (driver.h) Corrected the check for SQLITE3_USES_PTHREADS when
disabling SBRK_OK.
- (ed.c) The 'r' command leaked the filename (Bug #488).
31-Jun-2008 (Zesstra)
- (configure.in) Fix configure.in to work with autoconf 2.61 and later.
(patch from Fuchur, fixes bugs #541, #542)
30-Jun-2008 (Zesstra)
- (efuns.c) Added actual array size to error message 'Illegal array size'
in f_regexplode().
- (hosts/GnuWin32/GnuWin32.h, hosts/GnuWin32/socket.h)
Fixed #defines HOST_DEPENDENT_INIT and socket_number.
(Bug #497, thanks to Zonk_FF)
05-Jan-2008 (Gnomi)
- (efuns.c) The target index in the final copy loop must be incremented
only for actually copied elements.
27-Dec-2007 (Lars Duening)
- (i-eval_cost.h, efuns.c, lots of files) Replaced the eval-cost
increment macro with an inline function which does more checks
to prevent an overflow. Also, to allow proper catch() handling,
the eval_cost is capped at max_eval_cost+1 (suggested by Gnomi).
- (efuns.c) Having md5()/sha1() cost 10 ticks per iteration makes too
long evaluations more unlikely (suggested by Gnomi).
11-Nov-2007 (Lars Duening)
- (mstrings.c) mstr_rn_str() now allows a starting position at the
end of the input string (Bug #509).
- (efuns.c) sha1() and md5() now cost 5 ticks per iteration (Bug #485).
- (interpret.h, efuns.c, regexp.c) Introduced a macro to increment
both eval_cost and total_evalcost with a single statement.
11-Nov-2007 (Gnomi)
- (actions.c) Improvements for the removal of actions added by shadows
(Bug #514).
- (prolang.y) After two consecutive inline closures within the same
function, the line number information was incorrect (Bug #510).
- (lex.c) Corrected an off-by-one error related to auto-includes
by moving the line number adjustment from the CHAR_EOF handling
to the add_auto_include() function (Bug #508).
14-Oct-2007 (Lars Duening) (3.3.716)
- Created snapshot.
14-Oct-2007 (Gnomi)
- (prolang.y, lex.c) UNKNOWN identifiers are kept around until the
end of the compilation, as some parser rules can look-ahead multiple
tokens pointing to the same UNKNOWN identifier, so an early free
will lead to references to invalid memory. Keeping them that
long is a bit of overkill, but more future-proof (Bug #494).
- (prolang.y) Struct names are searched only the global namespace
as that is where structs are defined. Searched in the local
namespace can get the driver confused with references to
undefined structs. (Bug #493)
- (simul_efun.c) If a simul_efun object appeared before being blessed
explicitely, it may be an old backup copy. This situation is
now rejected as the variable/function definitions may differ
subtly. (Bug #489)
13-Oct-2007 (Lars Duening)
- (interpret, simulate.c) Changed the apply cache counters to 'unsigned
long' to reduce the possibility of an overflow (Bug #520).
- (interpret.c) setup_new_frame() now updates the csp->funstart entry
by itself, instead of having the caller do it. This is not just
more convenient, but also avoids problems with possible errors
during its execution (as the error handling will try to create
a stack trace). (Bug #495)
07-Oct-2007 (Lars Duening)
- (comm.c) When in charmode, don't attempt to read in as much data
as the buffer has left space: otherwise the handling of such an
'overlong command' confuses the charmode engine and causes the socket
to close prematurely. Yes, this is more a workaround than a real fix
(Bug #442).
- (simulate, interpret) The value thrown in a catch is now held in
the catch context could be leaked if a second error happens and
is caught in the master::runtime_error() handler (Bug #513).
- (configure) When testing for libiconv, reference a real libiconv method.
This catches situations where libiconv exists, but is of the
wrong architecture.
06-Oct-2007 (Lars Duening)
- (configure) gentoo Linux requires the '-n' argument for 'tail +2' to
work correctly (thanks, Juanjo!).
- (comm.c) Removed a crasher when running with --check-refcounts: References
by snooping non-interactives weren't counted (Bug #492).
- (sprintf.c) Removed a 64-bit issue (comparison of two values with
differing value ranges) (Bug #490)
- (prolang.y) upd_long() and read_long() weren't 64-bit-safe (even though
ins_long() already was) (Bug 491).
- (prolang.y) With the corrections to the inheritance handling done some
time ago, the lfuns backing inline closure can be again made 'private
nomask' (Bug #511).
- (simulate.c) load_object(): The object filename to load must not be
empty (Bug #500).
- (mstrings, obtable.c) Made sure that otable uses the same hasher
as mstring (Bug #500).
- (object, simulate.c) clone_object(): When initializing a clone's variables
using #pragma share_variables, really use the variables from the
blueprint object being given, not relying on the program.
This allows the handling of inherited blueprint objects with replaced
programs. (Bug #483)
- (simulate.c) replace_program(): If the program of a blueprint is replaced,
the old program's blueprint pointer is NULLed out as it is no longer
accurate. (Bug #483)
- (mudlib/uni-crasher/crasher.c) 'New' version from Bug #91.
- (my-rusage.h, files.c) Removed obsolete macro PROT() (Bug #504).
- (interpret.c) foreach(int i : <negative number>) now throws an error
(Bug #503).
03-Oct-2007 (Lars Duening)
- (mapping.c, object.c) Removed C-99 features.
01-Oct-2007 (Gnomi)
- (mapping.c) resize_mapping() didn't check for destructed objects as keys,
which made operations like map-([0]) after an object destruction
potentially fatal (Bug #517).
30-Sep-2007 (Lars Duening) (3.3.715)
- Created snapshot.
04-Nov-2006 (Lars Duening, Philip Hancke)
- (pkg-tls, main.c) Added new options --tls-crlfile and --tls-crldirectory
to hold the Certificate Revocation information.
- (pkg-tls, func_spec) New efun tls_refresh_certs() to reload the
certificates and certificate revocations.
09-Jul-2006 (Lars Duening) (3.3.714)
- Created snapshot.
14-Jun-2006 (Lars Duening)
- (array.c) Removed a memory leak when array intersection or subtraction
failed.
- (mapping, array, interpret.c, prolang.y) Implemented the array/mapping
intersection.
12-Jun-2006 (Lars Duening)
- Oh dear, has it been that long?
- (make_func.y) Modified a case of undefined behaviour in the creation
of the character classification tables: only 'unsigned char' types have
a defined overflow behaviour (thanks, Erik!)
- (configure) -fno-force-mem is deprecated.
09-May-2006 (Lars Duening)
- (xalloc.c) If the driver runs low on memory, it also prints the
current object and program in the low-on-memory message.
06-May-2006 (Lars Duening)
- (pkg-tls) New efuns hash() and hmac() offer flexible hash and HMAC
calculation if the driver is compiled to use OpenSSL (provided by
Philipp).
- (pkg-tls.c) Removed a compilation error occuring with GnuTLS.
- (lex.c) New macros __OPENSSL__ and __GNUTLS__ are set depending on
which TLS package is being used.
06-May-2006 (Gnomi)
- (prolang.y) Corrected the linenumber counting for inline closures.
23-Apr-2006 (Lars Duening)
- (mstring) The max hash length used is now available as macro constant.
- (otable.c) Both mstrings and C-strings are hashed with the same max
length. This corrects a bug with extremely long object names (Bug #466).
- (structs.c) The calculation of the first part of a struct's hash
uses what the mstring code has already calculated.
30-Mar-2006 (Lars Duening)
- (prolang.y) Removed a dead branch.
- (pkg-tls.c) Removed a possible compiler warning (Bug #464).
- (prolang.y) Removed a bison warning when structs aren't used.
27-Mar-2006 (Lars Duening)
- (pkg-tls.c) Added support for GEN_EMAIL, GEN_URI and GEN_DNS
certificates. tls_verify_callback() now prints diagnostics
only if the '-d' option was given (thanks, Philipp).
18-Mar-2006 (Gnomi)
- (interpret.c) In apply cache entries for non-existing functions, the
garbage collector counted the reference to the string name twice,
causing the use of deallocated memory (Bug #463).
16-Mar-2006 (Lars Duening)
- (comm.c) Moved the declaration of a variable which was declared in the
middle of a block - gcc doesn't complain, but it's not ISO-C (Bug #462).
14-Mar-2006 (Gnomi)
- (closure, object.c, interpret, exec.h, gcollect.c) lfun closures now
keep track to which program they belong, to avoid ambiguities
in case of complex inheritance relationships. This also affects
the savefile format: lfun closures are saved with their inheritance
path (Bug #443, #444).
- (prolang.y) If a non-virtual baseclass was inherited multiple times
with a virtual class inside the inheritance tree, its members
were merged even though they shouldn't (Bug #422).
- (prolang.y) The LPC compiler used a global variable for typetracking,
which caused errors when types changed inside a variable
initialisation (Bug #394).
12-Mar-2006 (Lars Duening) (3.3.713)
- Created snapshot.
- (comm.c) Master function disconnect() receives the remaining input data is
passed as the second argument (suggested by Philipp).
08-Mar-2006 (Malcom Tester)
- (lp-245/obj/master.c) Made the move implementation more robust.
07-Mar-2006 (Lars Duening)
- (pkg-tls.c) Two modifications to increase reconnect stability (thanks,
Philipp!).
- (prolang.y) Extended a LPC compiler warning when function indices
are adjusted.
06-Mar-2006 (Lars Duening)
- (backend, comm.c, object) The logon(obj) function moved from
backend.c into object.c, and was renamed logon_object() - it's
more sensical this way.
- (comm.c) If the master::connect() initiates a secure connection
which gets stuck in the handshake, neither logon() is called nor
is the prompt printed. Also, if the tls_init_connection() didn't
set a callback, the driver will provide a callback to logon().
This way logon() won't be called unless the connection is up
and running.
- (mudlib/psyc-tls.c) Example for using the tls_check_certificate()
efun (thanks, Philipp).
03-Mar-2006 (Lars Duening)
- (pkg-tls.c) tls_check_certificate() does more interpretation of
the result and returns better data (provided by Philipp).
01-Mar-2006 (Lars Duening)
- (interpret.c) A missing return is noted at runtime only once per
function. This is achieved by runtime code modification, but we
do that for switch() as well (Bug #430).
28-Feb-2006 (Lars Duening)
- (pkg-idna) Added support for International Domain Names (provided
by Philipp - thanks!).
- (configure, Makefile) Added a target 'install-headers' to install
all driver LPC header files.
- (simulate.c) Virtual blueprint objects are guaranteed to have their
'clone' flag unset.
- (string_spec, simulate.c) Renamed COMP_OBJ to the more intuitive
COMPILE_OBJECT.
- (interpret.c) Removed the stipulation that CATCH_RESERVED_COST
must be twice as much as MASTER_RESERVED_COST, since the master
reserve is used automatically anyway (suggested by Gnomi).
- (efuns.c) sscanf(): The new modifier '+' requires the matching of
the characters after a field in order to consider the field
as matched.
20-Feb-2006 (Lars Duening)
- (Makefile.in) Added a dependency to create patchlevel.h, even if
the program is made with 'make ldmud'.
20-Feb-2006 (Gnomi)
- (comm.c) remove_interactive() clobbered the current_object, setting
it to NULL. It is now preserved (Bug #431).
- (interpret.c) When executing an efun closure, the tracedepth wasn't
incremented accordingly (Bug #441).
- (simulate.c) When executing a non-toplevel callback, the tracedepth
should not be zeroed out (Bug #441).
08-Jan-2006 (Lars Duening)
- (make_func.y) When parsing the func_spec file, the preprocessor
conditionals were handled in a buffer in a no-longer existing
stack frame. So far, we were lucky, but on a 64-bit machine
that space was needed by the Bison parser.
- (driver.h, smalloc.c, slaballoc.c) If the machine uses a 8-Byte
malloc alignment (e.g. all PowerPC machines), the allocator does
not replace the system malloc().
- (mud/lp-245/) Since the recent change to how simul_efuns are called
(see Bug #419), the LP-245 lib was broken. This has been corrected.
05-Dec-2005 (Lars Duening)
- (configure, machine.h.in, config.h.in) Added a configuration check
for SQLite3.
- (pkg-sqlite, many files) Added SQLite support (Bug #11).
04-Dec-2005 (Gnomi)
- (prolang.y) Private lfuns no longer hide simul-efuns.
- (prolang.y) Private lfuns can be hidden by public functions without
warning, ie. the former are now really invisible to inheritors. This
also corrects a crasher with multi-level virtual inherits.
- (prolang.y) Multiple virtual inheritance of the same program with
changing visibility is now handled with a better calculation of
the final visibilities. (Bug #362)
04-Dec-2005 (Lars Duening)
- (interpret.c) Calling an unbound lambda cleaned the control stack
twice, causing errors (Bug #374).
- (simul_efun.c) Only public simul-efuns can be called. This was always
valid for sefuns outside the 256-range, but now also applies to
normal sefuns as well (Bug #419)
- (simul_efun, prolang.y, closure.c, interpret.c) The number of direct
callable simul-efuns is now configurable in the simul_efun.h. I
also increased it to 65536 from 256.
- (closure.c) Simul-efuns were still called with call_other instead
of call_direct.
02-Dec-2005 (Lars Duening)
- (gcollect.c) Added a log output when all objects are data-cleaned, as
it might be the cause for some observed slowdowns.
- (closure.c, interpret.c) For completeness sake: removed the compilation
errors happening when disabling the new inline closures (Bug #423).
27-Nov-2005 (Lars Duening)
- (object.c) Efun present(): Modified the <n> search behaviour so that the
numbering is applied over both inventory and environment
together. Before, the numbering was individual in each
space, leading to situations where low-numbered objects in the
environment were hidden by those in the inventory (Bug #417).
- (object.c) Efun function_exists(): The 'FEXISTS_ALL' result also contains
information about the function's type, flags, and number of
arguments (Bug #410).
26-Nov-2005 (Lars Duening)
- (efuns.c) Efun sscanf(): Added test whether the constant characters after
a %-field also match - if not, the %-field is considered unmatched
(suggested by Largo).
- (efuns, func_spec) Efuns md5()/sha1(): Accept the number of iterations as
optional argument (Bug #418).
24-Nov-2005 (Lars Duening) (3.3.712)
- Created snapshot.
- (md5.c) The ROTATE_LEFT macro wasn't 64-bit clean (Bug #413).
- (interpret.c) Using foreach(), when looping over a mapping with no values,
or with only the index being extracted, the loop actually loops over the
mapping and not just the indices copied into an array (Bug #388).
- (object.c) Efun set_environment(): clear the RESET_STATE flag of
of the moved object's original environment, if any (Bug #387).
- (efuns.c) Efun md5()/sha1() can now hash arrays of numbers as well
(Bug #411).
- (xalloc.c) The string_copy() function checks if the requested
memory is actually allocated, throwing an error if not (Bug #397).
- (simulate.c) Errors during the processing of a fatal() will be
recognized and treated as double-fatal (Bug #408).
- (interpret.c) free_svalue() now recognizes the free of nested
structures and de-serializes them to avoid stack overflows (Bug #416).
- (Makefile.in, version.sh, patchlevel.h.in) Removed PRCS support.
24-Nov-2005 (Gnomi)
- (actions.c) When re-using a sentence structure for marker_sent,
the shadow_ob member wasn't cleared out, causing crashes
down the road (Bug #0000414).
- (closure.c) bind_lambda() doesn't ignore unbindable closures
when the second argument is missing (Bug #407).
09-Oct-2005 (Lars Duening)
- (closure.c) replace_program_lambda_adjust() forgot to clear the
object references from the auxiliary lambda it created (Bug #0000412).
08-Oct-2005 (Lars Duening)
- (closure.c) When freeing bound unbound_lambdas, the code forgot to
remove the reference to the creator object of the unbound_lambda.
- (closure.c) Efun symbol_function() leaked an object reference (Bug
#0000412).
- (closure.c, object.h) Made the object reference logs a bit more
expressive.
31-Oct-2005 (Philipp Hancke)
- (pkg-tls.c) When accepting a SSL connection, request a client
certificate. The driver itself won't check the correctness,
but the result will be available in the connection status.
30-Oct-2005 (Lars Duening) (3.3.711)
- Created snapshot.
29-Oct-2005 (Lars Duening)
- (backend.c) The backend call to cleanup_all_objects() is now
controlled with a low/high watermark logic, to prevent
repeated calls in consecutive backend cycles: if one cleanup
didn't remove enough destructed objects, it is unlikely
that immediately following ones will.
- (pkg-tls.c) The OpenSSL read/writes are now retried when necessary.
- (configure) When searching for the mysqlclient library in the
usual places, the configure script forgot to clear out the
cache flag.
- (smalloc.c) Removed a compilation error when SBRK_OK wasn't defined.
- (mstrings, many files) The find-in-table statistics were done
incompletely.
- (structs.c) The test for struct equivalence now recurses through
member structs; otherwise changes in an contained struct wouldn't
be reflected in the containing struct.
- (prolang.y) Clarified the 'Unknown type' error messages when
derefencing structs.
19-Oct-2005 (Lars Duening)
- (pkg-tls.c) tls_check_certificate() now returns the low-level API
values, and throws an error if the connection is not secure.
11-Oct-2005 (Lars Duening)
- (erq/erq.c, xerq/socket.c) Corrected compilation warnings.
- (lex.c) to_int() no longer accepts "x<num>" as valid sedecimal
notation (Bug #0000402).
10-Oct-2005 (Lars Duening)
- (backend.c) Added a clear_state() at the beginning of the
process_objects() loop, so that errors during the cleanup find
a consistent machine state (Bug #0000405).
09-Oct-2005 (Lars Duening)
- (simulate.c) If the catch() handling notices an out-of-memory
situation, the catch() is ignored. This also fixes an endless
recursion (Bug #0000406).
04-Oct-2005 (Lars Duening)
- (doc/concepts/overloading) New man page (thanks, Coogan!).
28-Sep-2005 (Lars Duening)
- (doc/efun/clone_object) Clarified the variable initialisation.
23-Aug-2005 (Lars Duening)
- (Makefile.in) The PRCS rules first check if PRCS is available.
20-Jun-2005 (Lars Duening) (3.3.710)
- (patchlevel.h.in, version.sh, mk-patchlevel.sh, Makefiles)
Modified the version numbering system to be compatible between
Subversion and PRCS.
20-Jun-2005 (Lars Duening) (3.3.709)
- (xalloc.c) xalloc used REPLACE_MALLOC before it was defined,
leading to compilation errors on systems supporting it (Bug #0000393).
19-Jun-2005 (Lars Duening) (3.3.708)
- (pkg-pgsql, func_spec) Added new efun pg_conv_string(), courtesy
of Philipp.
- (efuns.c) Added new flag setting '4' to get_type_info() for closures
(Bug #0000392).
- (parse.c) Possibly corrected a refcounting bug in handling prepositions
(Bug #0000391).
- (closure.c) Since the operators #'&, #'|, #'^ and #'! are now considered
efuns, the closure compiler skipped the special treatment of these.
As an added bonus of the correction, #'| and #'^ can now take
an arbitrary number of arguments, too. (Bug #0000389)
10-Jun-2005 (Lars Duening) (3.3.707)
- (gcollect, backend.c) If the number of destructed pending objects
exceeds the number of active objects, a cleanup of all objects
is triggered. Also, the incremental cleanup in each cycle
cleans at least the number of objects destructed in the cycle.
06-Jun-2005 (Lars Duening) (3.3.706)
- (object.c, sprintf.c, structs.c) Removed a couple compilation warnings
on x86-64.
15-May-2005 (Lars Duening) (3.3.705 = 3.4.0)
- (simulate.c) runtime_error(), runtime_warning() and heart_beat_error()
received a new argument 'caught' (Bug #0000385).
15-May-2005 (Lars Duening) (3.3.704)
- (object.c) Single-character operator closures like #'- couldn't
be restored in arrays due to some outdated hack in the parser
(Bug #0000384 and #0000386).
15-May-2005 (Lars Duening) (3.3.703)
- (sprintf) sprintf("%c", 0) returned an empty string instead of a
string with the 0 character, because the code used the system
sprintf() for this formatting internally (Bug #0000378).
14-May-2005 (Lars Duening) (3.3.702)
- (sprintf) Printing structures with "%O" or "%Q" in non-compact
mode also prints the names of the structure members (Bug #0000380).
13-May-2005 (Lars Duening) (3.3.701)
- (configure) Added a check to see if the system is using a broken iconv
(part of glibc 2.0-2.2) - this iconv can throw the driver into an
endless loop (Bug #0000377).
13-May-2005 (Lars Duening) (3.3.700)
- (lex.c) When adding strings in preprocessor conditionals, the lhs
string was freed twice, causing memory corruption (reported by Tobias).
24-Apr-2005 (Lars Duening) (3.3.699)
- (config.h.in, gcollect.c) Added a specific define LOG_NEW_CLEANUP
to enable the logging of the automatic cleanup activity. This
is useful if the cleanup is suspicious of hogging the CPU.
- (main.c, pkg-tls.c) Improved the documentation for the TLS commandline
options, removed a crasher when only one of the two cert locations
is specified (thanks, Coogan!).
- (xalloc.c) Added warning if ptmalloc is used under FreeBSD.
- (configure) New configuration parameter '--with-tls-path' allows
to specifiy a non-standard location for the TLS installation.
01-Apr-2005 (Lars Duening) (3.3.698)
- (pkg-tls.c) Added FreeBSD 5.4 compatibility (thanks, Ralph!).
- (simulate, many files) Renamed error() to errorf() due to a collision
with gnutls.h include files under newer compilers.
01-Apr-2005 (Lars Duening) (3.3.696, .697)
- (port.c) Corrected a C99 incompatibility (thanks, Ralph!).
- (simulate.c, backend) The commands/s and compiled lines/s statistics
are part of the 'status tables' output.
- (gcollect.c) Added a missing variable initialisation (thanks, Ralph!).
27-Mar-2005 (Lars Duening) (3.3.695)
- (patchlevel.h, main.c, lex.c) Simplified the version number handling
in anticipation of the 3.4 branch.
27-Mar-2005 (Lars Duening) (3.3.694)
- (backend.c) I reintroduced the numeric limit on the number of objects
to data-clean, as even with the random factor it could happen
that the driver tries to cleanup hundreds of objects in one cycle.
The numeric limit is calculated such that all listed objects can
be cleaned in half of the configured cleanup cycle.
27-Mar-2005 (Lars Duening) (3.3.693)
- (slaballoc.c) Corrected the free-steps statistics.
- (backend.c) The data-cleanup didn't pay attention to the backend
timing, occasionally causing the driver to clean up thousands
of objects in one cycle.
- (gcollect.c) The cleanup of the fixed datastructures (wizlist, driver
hooks) did not observe the overall cleanup timing - on muds with
lots of data in the default wizlist entry this lead to annoying
lags.
25-Mar-2005 (Lars Duening) (3.3.692)
- (simulate.c) Modified the callback setup so that efun callbacks
can take normal lvalues; and timed function/closure callbacks
take protected lvalues - but not vice versa.
24-Mar-2005 (Lars Duening) (3.3.691)
- (gcollect.c) Added a log output for the time it takes to data-clean
objects.
- (config.h.in, slaballoc.c) The sorting of the partial slab freelists
is now configurable by hand.
- (slaballoc.c) Added weighted-average statistics for number of steps
per freed block.
- (interpret, backend.c, call_out.c, efuns.c heart_beat.c, simulate.c)
Added a statistic (last and time-weighted average) about the total
execution ticks and time per LPC thread.
20-Mar-2005 (Lars Duening) (3.3.690)
- (backend, main, simulate.c) Updated the last-data-cleaned statistics
to be weighted over time; and generalized the statistics implementation
in general.
18-Mar-2005 (Lars Duening) (3.3.689)
- (backend.c) Improved the synch heartbeat condition expression.
- (heartbeat.c) I had forgotten to remove all remnants of an exploratory
change.
17-Mar-2005 (Lars Duening) (3.3.688)
- (backend.c) The synchronous heartbeat timing wasn't initialised properly.
13-Mar-2005 (Lars Duening) (3.3.687)
- (main, backend.c, heartbeat.c) The ALARM_TIME and HEART_BEAT_INTERVAL
time are now configurable at compile and start time (based on
a patch by Gnomi).
12-Mar-2005 (Lars Duening) (3.3.686)
- (func_spec, object.c) The efun tell_object() can now take an array,
mapping, struct or object as second argument, calling catch_msg() in
the target in that case (Bug #0000354).
- (func_spec, object.c) The efuns tell_room() and say() can now take a
mapping, object or struct instead of an array as second argument for
the catch_msg() mechanism.
09-Mar-2005 (Lars Duening) (3.3.685)
- (mapping.c) The hash/hybrid statistics were somewhat off.
- (gcollect, backend.c, simulate.c) The default time interval for
a data cleanup is now available as macro in gcollect.h . And
since we have that time interval, the number-to-process limit
in process_objects() didn't make much sense anymore.
06-Mar-2005 (Lars Duening) (3.3.684)
- (slaballoc.c) Tuned the allocator: the partially-used slab lists
are now lazily order for better usage.
- (interpret.c) For an uncallable closure, the code forgot to clean
out the CSP before throwing the error (Bug #0000374).
- (doc/efun/snoop) Corrected the description of the return value (Bug
#0000372).
26-Feb-2005 (Lars Duening) (3.3.683)
- (efuns.c) regreplace() didn't update the stack pointers properly,
causing crashes down the road (reported by Bardioc).
25-Feb-2005 (Lars Duening) (3.3.682)
- (mapping.c) Indexing a mapping with strings didn't quite work yet: the
hash computation didn't take into effect that strings are no longer
tabled just to use them as rvalue indices.
- (simulate.c) If a callback didn't have a valid object associated with
it (e.g. unbound_lambda()s), the code forgot to remove the arguments
from the stack (Bug #0000370).
- (simulate.c) Uncalleable closures given as callbacks are now detected
and cause a runtime error (Bug #0000370).
- (simulate.c) A runtime in a regreplace() substitution closure leaked
the regexp structure. I changed the whole thing to automatic
cleanup (Bug #0000370).
24-Feb-2005 (Lars Duening) (3.3.681)
- (mstrings) Re-integrated the stringtable structures into the strings:
on the whole, the majority of strings will be tabled so reducing
the overhead for this case is beneficial.
24-Feb-2005 (Lars Duening) (3.3.680)
- (mstrings, closure.c, interpret.c) Debugging 3.3.679: reallocating a
string 'under the hood' is no longer possible as the string data is now
an integral part of the string structure. This disables the
mstr_append() optimizations.
21-Feb-2005 (Lars Duening) (3.3.679)
- (mapping.c) get_map_lvalue() didn't correctly check the mapping size:
it checked against the current and not the future size (Bug #0000369).
- (mapping, simulate.c) Added a statistic for hash and hybrid mappings (for
now just the count).
- (mstrings, gcollect.c, array.c, closure.c, i-svalue_cmp.h, interpret.c,
simulate.c) Simplified the string implementation to reduce the overhead.
21-Feb-2005 (Lars Duening) (3.3.678)
- (slaballoc.c, smalloc.c) I hate crashers which don't happen on my machine:
the merging of the esbrk() result with adjacent free blocks crashed
the driver (Bug #0000368).
20-Feb-2005 (Lars Duening) (3.3.677)
- (configure, mapping.c, simulate) It is now possible to determine
the max number of mapping entries (keys) in addition to the total
mapping size (Bug #0000360).
- (main.c) New commandline option '--max-mapping-keys' to determine
separately the maximum number of entries in a mapping.
20-Feb-2005 (Lars Duening) (3.3.676)
- (smalloc.c) Corrected a crasher in realloc().
- (smalloc.c, slaballoc.c) New memory allocated with esbrk() is now
coagulated with existing free memory if possible (Bug #0000364).
20-Feb-2005 (Lars Duening) (3.3.675)
- (pkg-tls.c) Removed compilation errors when using GnuTLS.
- (comm.c) The charmode/noecho mode is changed in remove_input_to()
only if the first pending input_to() is removed. Hopefully this
fixes Bug #0000363.
20-Feb-2005 (Lars Duening) (3.3.674)
- (prolang, simulate.c) During the compilation of the master object, simul
efuns are disabled.
20-Feb-2005 (Lars Duening) (3.3.673)
- (smalloc.c, slaballoc.c) The memory block size computation failed
on large blocks, giving bad statistics.
13-Feb-2005 (Lars Duening) (3.3.672)
- (pkg-tls.c) Philip provided a tls_check_certificate() efun.
12-Feb-2005 (Lars Duening) (3.3.671)
- (pkg-tls.c) My change was premature.
- (mstrings.c) The printing of percent values was missing a conversion
to float in order to actually compute the percent values.
11-Feb-2005 (Lars Duening) (3.3.670)
- (mstrings.c) The extended string statistics didn't count the tabled
comparisons correctly.
- (lex.c) New macro __BOOT_TIME__ expands to the time() the driver
was booted.
- (comm, pkg-tls.c) New interactive_t flag 'outgoing_conn' is TRUE for
connections openened by net_connect(). This is used by TLS (OpenSSL)
to set the proper state for the session.
- (slaballoc.c, smalloc.c) When using brk() for core allocation, the
returned memory address was one word too low.
09-Feb-2005 (Lars Duening) (3.3.669)
- (object, simulate.c, backend.c) The list of destructed-but-referenced
objects is scanned for deallocatable objects only when a flag
signals that there actually are candidates. This should reduce
the CPU load when destructed objects accumulate.
- (mstrings, various files) Added statistics to check how much the
shared string table actually helps performance. They are printed
in the 'status tables' command.
07-Feb-2005 (Lars Duening) (3.3.668)
- (smalloc.c, slaballoc.c) The large block handler is now capable
of handling blocks up to 2**32 words. This is especially useful
on systems using malloc() instead of sbrk() for core memory
allocation (reported by Menaures).
- (efuns.c, smalloc.c, slaballoc.c) The extended malloc statistics
are now separate from 'status malloc' in 'status malloc extstats'
(Bug #0000358).
01-Feb-2005 (Lars Duening) (3.3.667)
- (pkg-mccp.c) In start_mccp_compress(), the interactive pointer
was used before being set. I moved the set&check forward
(Bug #0000361).
- (pkg-tls.c) The success code passed to the TLS-handshake callback
was incorrect: on success, it was passed as '1' instead of '0'
(reported by Philipp).
31-Jan-2005 (Lars Duening) (3.3.666)
- (xalloc.c) Forgot to remove a fatal() used to debug slaballoc (Bug
#0000359).
- (slaballoc.c) Removed compiler warnings (Bug #0000358).
- (mregex.c) Great - Kerberos has a function 'error_message()' in
a global include file (reported by Rajko).
- (comm.c) Do not print the prompt to interactives which are currently
negotiating a TLS handshake.
- (pkg-tls.c) During the execution of a tls-init callback, the callback
is protected against premature freeing.
- (interpret.c) The range foreach (i: __INT_MIN__ .. __INT_MAX__)
now works as well (I added an internal flag for this case to allow one
extra pass through the loop (Bug #0000355).
- (pkg-mccp.c) With the telnet machine disabled, it is now possible to
still use outgoing compression with start_mccp_compression(), assuming
a suitable client program is used on the other end (suggested by
Philipp).
30-Jan-2005 (Lars Duening) (3.3.665)
- (interpret.c) foreach(i: x..__INT_MAX__) never executed because
of internal overflow. By changing the meaning of the internal 'count'
from 'upper limit' to 'iterations left', this overflow was
avoided (Bug #0000355).
30-Jan-2005 (Lars Duening) (3.3.664)
- (xalloc, slaballoc, configure, efuns.c) Added new 'slaballocator'
which provides a better use of the free small block storage.
- (interpret.c) When using foreach() on references, the protector
structure was allocated too small - a stupid typo (Bug #0000353).
22-Jan-2005 (Lars Duening) (3.3.663)
- (actions, simulate, gcollect.c) Unused action and shadow sentences
are no longer held in a freelist, but instead returned directly
to the memory allocator.
22-Jan-2005 (Lars Duening) (3.3.662)
- (efuns.c) Deep-copying a mapping employing shared arrays as keys (e.g. ([
arr, ([ arr ]) ])) prematurely freed the copied array as the code
didn't keep track of the copied data itself, but of the svalues it was
stored in - and for mapping keys these svalues were local variables
(Bug #0000351).
- (comm.c) If telnet-negs were turned off in linemode, the driver started
treating lineends as if in charmode, which the higher routines
didn't expect (reported by Philip).
19-Jan-2005 (Lars Duening) (3.3.661)
- (gcollect.c) When a program was swapped out, the GC didn't clear the refs
of its name (Bug #0000348).
- (mregex.c) If a regexp function was asked to use both RE_TRADITIONAL
and RE_PCRE, and the regexp doesn't compile for both, the resulting
error leaked some structures (Bug #0000349).
17-Jan-2005 (Lars Duening) (3.3.660)
- (gcollect.c) The names of programs of destructed objects didn't
get their references cleared properly in a GC, leaking the
program names if the destructed object was held by
a self-reference (Bug #0000099).
- (closure.c) Determining the closure location leaked the
program's name (Bug #0000347).
16-Jan-2005 (Lars Duening) (3.3.659)
- (configure) Corrected the mySQL library check (Bug #0000346).
14-Jan-2005 (Lars Duening) (3.3.658)
- (interpret, array.c, mapping.c, parse.c, simulate.c, files.c)
The new function push_error_handler() simplifies the creation
of T_ERROR_HANDLER values.
- (object.c) Exceptions during a restore no longer leak values
(Bug #0000344).
- (smalloc.c) The extended large-free statistics was still off.
14-Jan-2005 (Lars Duening) (3.3.657)
- (array.c) Efun unique_array() no longer leaks memory if aborted
by an exception (Bug #0000345).
14-Jan-2005 (Lars Duening) (3.3.656)
- (gcollect.c, object.c) The GC forgot to clean out the refcounts
of the names of the destructed objects, which meant that if
the destructed object was held by a self-reference, the name
would receive an extra reference count and leak until the
next GC (Bug #0000343).
14-Jan-2005 (Lars Duening) (3.3.655)
- (backend.c) Tweak to the process_objects() loop: the loop now
really allows to have a given number of objects being cleant
per loop, not just checked for being cleanable.
14-Jan-2005 (Lars Duening) (3.3.654)
- (smalloc.c) Small block splits now make sure, that the remaining
block has a minimum size. This size is currently configured
to 3 words = 12 Bytes, as the driver doesn't need that many
of the even smaller blocks.
- (object, gcollect.c, backend.c) The data cleanup is now timed
independent of the time of the last reference: similar to
reset the cleanup takes place in random intervals based
on the configured cleanup-time (or one hour if the cleanup-time
is 0).
13-Jan-2005 (Lars Duening) (3.3.653)
- (util/xerq/erq.c) The erq didn't check if the calculated timeout
for the next select() had become negative. (Bug #0000342).
12-Jan-2005 (Lars Duening) (3.3.652)
- (mapping.c) Indexing a 0-width mapping returned pointers to memory outside
the mapping, causing weird crashes. The solution is to return pointers
to the global const1 (when found), or to a local svalue-0 instance
(when not found and a lvalue is requested) (Bug #0000341).
10-Jan-2005 (Lars Duening) (3.3.651)
- (configure) Added yet another path to the search for a mySQL installation.
09-Jan-2005 (Lars Duening) (3.3.650)
- (doc/efun/send_udp) Added a note about the blocking behaviour of
name lookups.
- (configure) The mySQL test was not quite correct.
09-Jan-2005 (Lars Duening) (3.3.649)
- (configure) Added another path to the search for a mySQL installation.
08-Jan-2005 (Lars Duening) (3.3.648)
- (settings/timewarp) New settings file.
- (mudlib/sys/files.h, files.c) Efun get_dir() can now return
access times and file modes (suggested by Mats).
08-Jan-2005 (Lars Duening) (3.3.647)
- (configure, pkg-mysql.c) Adjusted the search for the mySQL include
files to allow for local installations (Bug #0000338)
08-Jan-2005 (Lars Duening) (3.3.646)
- (func_spec, lex, prolang.y, interpret.c) New pragma 'range_check'
allows to check the validity of array ranges at runtime - these
are the range checks currently controlled by the warn_deprecated
pragma.
08-Jan-2005 (Lars Duening) (3.3.645)
- (smalloc.c) Corrected some bugs in the extended statistics.
- (comm, simulate.c, mudlib/sys/debug_info.h) Added statistics for
the incoming network traffic, and also display the total
amount of data sent/received in the 'status tables' command.
04-Jan-2005 (Lars Duening) (3.3.644)
- (main.c, doc/driver/invocation, INSTALL) Corrected the documentation
(Bugs #0000333 and #0000335).
31-Dec-2004 (Lars Duening) (3.3.643)
- (mapping.c) Corrected the hashing function so that for efun/sefun/operator
closures the object information is no longer part of the hash. Without
that, mappings treat closure keys differently than the '=='/'!='
operators, which is not a good thing.
31-Dec-2004 (Lars Duening) (3.3.642)
- (lex.c) Factored the handling of preprocessor statements and of
closures out of the yylex switch.
29-Dec-2004 (Lars Duening) (3.3.641)
- (closure, object.c) The driver internally now uses the closure creation
functions as well - there were more places where lambdas were
initialized by hand than I expected to be.
- (closure.c) The location determination for closures didn't check
carefully enough if the pc was correct or not.
28-Dec-2004 (Lars Duening) (3.3.640)
- (pkg-mysql.c) Most mySQL efuns are now privileged as ("mysql", "<efun
name>") (Bug #0000318).
- (pkg-pgsql.c) All Postgres efuns are now privileged as ("pgsql", "<efun
name>").
28-Dec-2004 (Lars Duening) (3.3.639)
- (interpret) inter_pc is now always visible, as it's needed by the
closure origination tracking.
- (closure) Added functions to create basic closure types, primarily
so that other closure creators (like FinalFrontier's stringcompiler)
don't have to do it by hand (and break with every change to the
closure structure).
27-Dec-2004 (Lars Duening) (3.3.638)
- (mudlib/sys/tls.h) Corrected (Bug #0000331)
- (doc/efun/m_values) Explained the lack of predictable order in the result
(Bug #0000329)
- (closure, gcollect.c, interpret.c) Non-operator/efun/sefun closures now
keep a reference to the program location where they are created, for
more informative printing (error messages and otherwise).
23-Dec-2004 (Lars Duening) (3.3.637)
- (comm.c, sys/input_to.h) The input_to() flag INPUT_APPEND allows
to queue input_to()s (suggested by Volker Behr).
23-Dec-2004 (Lars Duening) (3.3.636)
- (lex, efuns.c) Another small correction to the number parsing in to_int():
negative numbers exceeding the limits are properly mapped to INT_MIN,
not -INT_MAX. Unfortunately too large negative numbers seen by
the LPC compiler are still mapped to -INT_MAX due to the lack
of proper overflow handling in the compiler; however, the compiler
now emits a warning on these occasions.
- (comm.c, pkg-tls.c) More TLS bugfixes by Fippo and Peng (Bug #0000138 and
#0000140).
22-Dec-2004 (Lars Duening) (3.3.635)
- (pkg_tls, func_spec, configure) Incorporated the GNUTLS patches from Peng
and Gawain: use the new gnutls parameter generation if available;
properly handle threading; don't request a client certificate since we
don't need it; and the new fun tls_available() returns whether the
TLS package could be initialized or not (Bug #0000082).
22-Dec-2004 (Lars Duening) (3.3.634)
- (func_spec, efuns.c) New efun regexp_package() to determine the
currently active default regexp package.
22-Dec-2004 (Lars Duening) (3.3.633)
- (prolang.y) The no-warn-deprecated opcodes weren't included in the
size calculations for the lvalue indexing shuffling.
- (lex.c, efuns.c) The overflow checking in the number parsing routine
was overeager, causing Evermore to no longer boot. The checking
now really compares against the largest possible number, instead
of simply checking the sign (Bug #0000327).
21-Dec-2004 (Lars Duening) (3.3.632)
- (lex.c) The number parsing now recognizes overflows and forces these
numbers to be LONG_MAX (Bug #0000327).
- (mstrings.c) mstring_realloc_string() (used for example to append
to strings) didn't check if the string was indirectly tabled,
potentially freeing memory which was still in use otherwise
(reported by Bardioc).
- (settings/evermore) Updated to the latest version.
- (prolang.y, interpret.c) The array indexing warnings are now controlled
by the warn_deprecated pragma (Bug #0000325).
18-Dec-2004 (Lars Duening) (3.3.631)
- (interpret.c) Assignments to negative-sized ranges now throw
an error; indexing of ranges with out of bounds limits generate
warnings (Bug #0000325).
- (interpret.c) In DEBUG mode: when setting up an inherited call, check
that the given inherit index is sensible.
17-Dec-2004 (Lars Duening) (3.3.630)
- (xalloc) Added a new function prexalloc() to re-allocate permanent
memory.
- (pkg-tls.c) The allocator for the TLS package of course needs to
allocate permanent memory so that the GC won't deallocate
the library's memory (Bug #0000323).
11-Dec-2004 (Lars Duening) (3.3.629)
- (gcollect.c) Closures found to be bound to destructed objects are
replaced by 0s, not #'undef closures (Bug #0000322).
- (closure) The function store_undef_closure() is no longer needed.
09-Dec-2004 (Lars Duening) (3.3.628)
- (xalloc.c) Modified xalloc() to accept allocations of size 0 (again as the
C standard demands).
07-Dec-2004 (Lars Duening) (3.3.627)
- (pkg-tls.c) Added allocation wrapper so that gnutls allocations can
be traced using the driver's mechanisms (thanks, Peng!)
- (xalloc.c) Modified rexalloc() and xfree() to accept NULL pointers
as well (as the C standard demands) (Bug #0000132).
06-Dec-2004 (Lars Duening) (3.3.626)
- (erq/erq.c) The erq didn't quite use correct data lengths when sending UDP
packets, either (thanks, Tobias!)
03-Dec-2004 (Lars Duening) (3.3.624, .625)
- (erq/erq.c) The erq errorneously assumed a constant data length
when receiving UDP packets (thanks, Tobias!)
- (comm.c, object.c) The driver didn't check if the privilege_violation()
called for input_to() or rename_object() destructed the object
in question (Bug #0000316).
30-Nov-2004 (Lars Duening) (3.3.623)
- (comm.c) Fixed a memory leak when a no-bank input_to was denied (Bug
#0000143)
29-Nov-2004 (Lars Duening) (3.3.622)
- (interpret.c) When indexing a string for assignment, the driver failed
to duplicate the string, leading to interesting effects if the string
was used as mapping key (reported by Andre).
27-Nov-2004 (Lars Duening) (3.3.621)
- (interpret.c) When calling inherited functions in objects with virtual
parents, the function adjusting the offsets always returned NULL
instead of the pointer to the parent. This was a fallout from the
closure change.
26-Nov-2004 (Lars Duening) (3.3.620)
- (Makefile.in, doc/man/ldmud.1) Added the automatic generation of a manpage
from the drivers '--longhelp' output.
- (src/bugs, src/done, src/wk) Moved the data from these directories
into the bugtracker.
26-Nov-2004 (Lars Duening) (3.3.618, .619)
- (closure.c) Calls to explicitely inherited lfun closures weren't compiled
correctly in lambda()s (Bug #0000145).
25-Nov-2004 (Lars Duening) (3.3.617)
- (prolang.y) When the new inline closures were disabled, the LPC compiler
produced incomplete code for the inline closure constants, and
the interpreter didn't interpret it correctly either.
24-Nov-2004 (Lars Duening) (3.3.616)
- (closure, gcollect.c, interpret.c, object.c prolang) Implemented proper
closures explicitely referencing inherited functions.
22-Nov-2004 (Lars Duening) (3.3.615)
- (comm.c) Efun net_connect(): on multihomed machines the created
socket is bound to the hostname given with the --hostname option (Bug
#0000137).
15-Nov-2004 (Lars Duening) (3.3.614)
- (efuns.c) You learn a new thing every day: I never realized that
strtol() supports "+34" and similar - efun to_int() can now
interpret that again, too (reported by Bardioc).
13-Nov-2004 (Lars Duening) (3.3.613)
- (lex.c, efuns.c) Embarassing: the number parsing method assumed that the
string at least started with a digit - this broke to_int().
(Bug #0000141)
12-Nov-2004 (Lars Duening) (3.3.612)
- (pkg-alists.c) Efun insert_alist() no longer returned the insertion
position for keys not yet in a key array (reported by Bardioc).
11-Nov-2004 (Lars Duening) (3.3.611)
- (efuns.c, lex) Efun to_int() now supports the '0x', '0b', and '0o'
bases (suggested by Steve Goucher).
30-Oct-2004 (Lars Duening) (3.3.610)
- (func_spec, object.c) Introduced the (str, n) form for efun present()
(Bug #0000134).
26-Oct-2004 (Lars Duening) (3.3.609)
- (smalloc.c) Ok, ordering the small block freelists was a bad idea - I
removed that now. Ordering the large block freelists doesn't seem
to make a performance difference, so I keep it in for now.
24-Oct-2004 (Lars Duening) (3.3.608)
- (backend.c) Reduced the frequence of data-cleanup such that at least
time_to_clean_up seconds (or 3600 seconds) must have passed since
the last reference.
- (smalloc.c) smalloc now supports allocations of 0 byte length (needed
to replace malloc()).
14-Oct-2004 (Lars Duening) (3.3.607)
- (comm.c) The NOECHO hook call specified only two arguments when
three were required (reported by Bardio and Steve G.).
11-Oct-2004 (Lars Duening) (3.3.606)
- (mregex.c) Added a number of NULL pointer checks to the deallocation
of regular expressions (reported by Bardioc, #0000130, #0000135).
29-Sep-2004 (Lars Duening) (3.3.605)
- (smalloc.c) Corrected a bug in the SMALLOC_ORDER_FREELIST code for
small blocks: the code forgot to store the block size into the
free blocks, which caused the defragment code to do wondrous things
(reported by Bardioc).
27-Sep-2004 (Lars Duening) (3.3.604)
- (pkg_tls.c) Corrected the callback handling for tls_init_connection()
(Bug #0000131).
- (driver.h) Added a macro MIN() for those systems which don't have it.
16-Sep-2004 (Lars Duening) (3.3.603)
- (config.h.in, smalloc.c, xalloc, main.c, sysmalloc.c, xptmalloc.c)
New manual config.h macro MALLOC_EXT_STATISTICS enables extended
block statistics in smalloc. The statistics can be retrieved
with debug_info(DINFO_DATA, DID_MEMORY), and are also printed as
part of the 'status malloc' command. This is an experiment to
see if we can get more information about the small heap
fragmentation this way.
15-Sep-2004 (Lars Duening) (3.3.602)
- (config.h.in, smalloc.c, main.c) New manual config.h macro
SMALLOC_ORDER_FREELISTS instructs smalloc to keep its freelists ordered
by block address. This is an experiment to see if the high heap
fragmentation can be reduced this way.
12-Sep-2004 (Lars Duening) (3.3.601)
- (prolang.y, lex) New pragma (no_)warn_function_inconsistent to control
the handling of redefined functions which differ in return or argument
types. This is intended to easen the adaptation of legacy mudlib
code (suggested by Wayne).
12-Sep-2004 (Lars Duening) (3.3.600)
- (prolang.y) When checking the redefinition of inherited variables, do
allow the redefinition of static inherited variables with other
static variables (it will generated warning, though). Also the
equivalency of nosave and static was applied too late (reported by
Willem).
- (func_spec, efuns.c, main) Added an 'exit code' argument to the shutdown()
efun (Bug #0000129).
- (func_spec, interpret.c, prolang.y) The pragma warn-deprecated is now
expressed through a prefix bytecode where appropriate (Bug #0000059,
#0000093).
09-Sep-2004 (Lars Duening) (3.3.599)
- (mregex.c) On a collision in the hash table, the regdata_t structure
was freed with a call to free_regexp() - not good (Bug #0000128).
07-Sep-2004 (Lars Duening) (3.3.598)
- (main, mregex.c, simulate.c) The H_REGEXP_PACKAGE hook can now accept
the value 0 to fall back onto the package defined by the commandline
arguments/configuration.
06-Sep-2004 (Lars Duening) (3.3.597)
- (ed.c, lex.c, mregex) Removed USE_PCRE remnants which among other things
disrupted compilation (Bug #0000126).
04-Sep-2004 (Lars Duening) (3.3.596)
- (mregex, simulate.c, efuns.c) Implemented the concurrent use of both
regexp packages.
04-Sep-2004 (Lars Duening) (3.3.595)
- (configure, main.c, simulate.c) Added the glue to select a default
regexp package via commandline option or driver hook. The regexp
logic itself is still unchanged.
04-Sep-2004 (Lars Duening) (3.3.594)
- (mregexp, ed.c) Changed the regexp implementation to use a pImpl
idiom - this will allow to use traditional regexps and PCRE
in parallel.
04-Sep-2004 (Lars Duening) (3.3.593)
- (comm.c, simulate.c) Added new input_to() flag 'INPUT_LOCAL' to switch
only the driver side input mode between LINE and CHAR (Bug #0000124).
03-Sep-2004 (Lars Duening) (3.3.592)
- (interpret.c, simulate.c) Removed memory leaks (thanks, Gnomi!)
(Bug #0000120).
- (sprintf.c) Too large fieldsizes or precisions are caught (Bug #0000119).
- (closure, object.c) Some operator closures were saved using the wrong
names, making the restoration impossible. Also, restoring closures
within arrays wasn't robust enough (Bug #0000118).
- (comm.c) Clarified the warnings for input_to modechanges for objects
with telnet disabled (Bug #0000124).
- (comm.c) When switching out of CHARMODE, the driver accidentally
discarded any pending input lines after the current one. (thanks,
Gnomi) (Bug #0000123)
01-Sep-2004 (Lars Duening)
- (pkg-tls.c) Added a bugfix to the session creation (thanks, Phillipp!)
31-Aug-2004 (Lars Duening) (3.3.591)
- (prolang.y) The real correction to the memory corruption problem: it
happened when an inline closure returned a struct, because the
compiler derefenced the returntype entry during the cleanup even
though it was an uncounted reference. The problem however showed
up only when the compilation failed and the struct involved was
a private struct, because in all other cases the struct had enough
references left to survive.
30-Aug-2004 (Lars Duening) (3.3.590)
- (prolang.y) The move of the PREPARE_INSERT() in the last patch caused
the driver to generate faulty bytecode.
- (prolang.y) Function definitions didn't count the reference for the
returntype, which lead to memory corruption/crashes when handling
struct returntypes. Unfortunately now we have a memory leak
when structs are used as returntypes - there is something to be said for
using C++... (reported by Bardioc).
23-Aug-2004 (Lars Duening) (3.3.589)
- (prolang.y) Removed a C99 construct which broke compilation on C90
compilers. I hope. (Bug #0000116).
23-Aug-2004 (Lars Duening) (3.3.588)
- (array.c, pkg-mccp.c) Removed compiler warnings (thanks, Andre).
22-Aug-2004 (Lars Duening) (3.3.587)
- (interpret.c) Calls from destructed objects to other objects
(including simul-efun calls) now elicit a warning (Bug #0000113).
- (configure, config.h, mregex, pkg-pcre, main.c) The driver now tries
to use the system's PCRE library if available, while offering an
override to use the builtin package regardless.
21-Aug-2004 (Lars Duening) (3.3.586)
- (interpret.c) If a lambda was executed inside a catch() and threw an
error, the error routines didn't clean up the protective reference
held in current_lambda (Bug #0000114).
- (efuns.c) to_string(closure) leaked the closure (Bug #0000114).
- (ed.c) The 'M' command leaked the regular expression (Bug #0000114).
19-Aug-2004 (Lars Duening) (3.3.585)
- (prolang.y, interpret.c, func_spec) Float variables without initializer
are now properly initialized to float-0 instead of number-0 (reported
by Bardioc).
- (pkg-mccp.c) When ending a MCCP connection failed due to an error, the
zlib datastructures weren't deallocated (Bug #0000111, fix by Alwin).
08-Aug-2004 (Lars Duening) (3.3.584)
- (simulate.c) When printing a load-object error with a long filename,
the message is limited to the length of the error message buffer (Bug
#0000109).
- (simulate, xalloc.c) The length of the error message and error format
buffer are now given by two macros, to facilitate easier adaptation
of depending program segments.
01-Aug-2004 (Lars Duening) (3.3.583)
- (backend.c) If the garbage_collection() couldn't open a passed file,
the filename was leaked (reported by xtian).
- (mstrings.c) Corrected the statistics display for itabled strings.
- (smalloc.c) The allocated small block statistics was confused by
the mem_increment() feature.
29-Jul-2004 (Lars Duening) (3.3.582)
- (lex.c) The macros __FLOAT_MIN__ and __FLOAT_MAX__ now reflect
the limits for 'double' floats (Bug #0000101).
28-Jul-2004 (Lars Duening) (3.3.581)
- (call_out.c) When printing the uid for an object with an error, make
sure that there is an uid to print (reported by Bardioc).
- (mudlib/crashleak.c) Donated by Menaures: a modification of the crasher
object, looking for memory leaks (Bug #0000102).
25-Jul-2004 (Lars Duening) (3.3.580)
- (interpret.c) If the struct lookup operator receives arguments of
the wrong type, it just throws an error instead of crashing the
driver, as this can happen with careless funcall(#'->)s (Bug #0000097).
- (efuns.c) to_array('symbol) crashed the driver because it tried to
free the symbol as a string (Bug #0000097).
- (interpret.c) The trace collection into an array now uses unlimited
arrays, otherwise a too-small limit would cause the driver
to enter an endless error loop (Bug #0000097).
- (object, gcollect.c) If a save_{object,value} failed and thus
left a pointer table behind, a following GC would free the table
without resetting the pointer. The next save_{object, value} would
then use the freed memory (Bug #0000097).
25-Jul-2004 (Lars Duening) (3.3.579)
- (xerq/erq.c) If select() in the main loop was interrupted by a signal,
the ERQ still proceeded to evaluate the fd-sets.
- (xerq/execute.c) The debug logging of the execute parameters didn't
work.
- (comm.c) If an ERQ callback function accepts an array, the numbers
are now all passed on positive (range 0..255).
24-Jul-2004 (Lars Duening) (3.3.578)
- (xerq/defs.h) ERQ_DEBUG level wasn't properly translated into
debug output.
- (xerq/socket.c) Added a few level 2 diagnostics.
- (interpret.c) Removed two left-over DEBUG diagnostics (reported
by Bardioc).
- (comm.c) input_to() didn't properly check its arguments (Bug #0000098).
- (call_out.c) If a call-out causes an error, all further call-outs for
the same user are re-scheduled to the next cycle. This is mainly
meant to stop run-away call-outs causing too-long-evaluations while
re-scheduling calls to themselves (Bug #0000095).
21-Jul-2004 (Lars Duening) (3.3.577)
- (array.c, interpret.c) Removed a number of memory leaks caused by
runtime errors during array operations which exceeded the max
array size (Bug #0000096).
- (comm.c) If input_to() wasn't given a valid prompt, it leaked
the memory for the internal input-to structure (Bug #0000096).
- (comm.c) If binary_message() was given an array of non-ints, it leaked
the memory for the internal message string (Bug #0000096).
- (bitstrings.c) The bitstring operators would leak the memory for
the result if encountering an invalid bitpattern (Bug #0000096).
- (files.c) If tail() couldnt' find the file, it didn't free the
string with the pathname (Bug #0000096).
16-Jul-2004 (Lars Duening) (3.3.576)
- (interpret.c) When printing a warning during the creation of in inline
closure, the global stack pointer was one too low (thanks, Gnomi)
(part of Bug #0000091)
14-Jul-2004 (Lars Duening) (3.3.575)
- (prolang.y) The 'missing return' warning is no longer triggered if
a function ends with raise_error() or throw().
- (comm.c) Efun input_to(): the check for a change in the CHARMODE mode
did not properly check if the command_giver was valid - this could
cause a segfault if input_to() was used without an interactive (Bug
#0000090).
- (smalloc.c) If the allocation exceeds the numerical limits and the
allocation is not in MALLOC_SYSTEM mode, a simple diagnostic is printed
and the allocation fails. This way, an " "*MAX_INT won't crash
the mud. (Bug #0000086)
- (array.c) The array allocation now checks if the size of the requested
array exceeds the numerical limits (part of Bug #0000091)
13-Jul-2004 (Lars Duening) (3.3.574)
- (prolang.y) The 'public foo() shadows private bar()' warning no longer
warns about the __INIT() function (Bug #0000085).
- (efuns.c) Removed a memory leak in ctime( <vector> ) (Bug #0000087).
- (simulate.c) In catch(), the check if there are enough evals left
was done before the reserve had been added to the eval cost. Since
the handling for this case was changed to a runtime error, this
caused the error handler to subtract a reserve which wasn't there,
in the process messing up eval cost handling (Bug #0000088).
- (simulate.c) The restoration of eval limits didn't handle the case
of a fixed eval cost (USE_EVAL_COST > 0) correctly if the process had
used more than the given amount: the total eval cost was set to the
given amount, instead of adding the amount to the previous eval cost
value (Bug #0000077).
12-Jul-2004 (Lars Duening) (3.3.573)
- (actions.c) Efun remove_action() didn't check if the sentence under
scrutiny is a true verb or a shadow sentence - this caused a crash
if a shadow object executed remove_action(1, shadowee) (Bug #0000080).
11-Jul-2004 (Lars Duening) (3.3.572)
- (comm.c, actions.c) On a too long message or command, print the
first 200 characters as debugging aid (Bug #0000078).
10-Jul-2004 (Lars Duening) (3.3.571)
- (interpret.c) The tracedepth was always increased, but only decreased
when traceing was active (#0000070)
10-Jul-2004 (Lars Duening) (3.3.570)
- (pcre/) PCRE no longer directly changes the EVAL_COST, instead the
MATCH_LIMIT option is used to limit the execution of backtracking
expressions. Updated the documentation. (Bug #0000075)
08-Jul-2004 (Lars Duening) (3.3.569)
- (pcre/) Upgraded PCRE to version 4.5; however, there is additional work
to be done as PCRE 4.5 offers additional features (Bug #0000075)
01-Jul-2004 (Lars Duening) (3.3.568)
- (doc/efun/previous_object) Corrected to reflect actual behaviour (Bug
#0000073).
- (lex.c) The symbol __MAX_MALLOC__ is set to what is actually set
in the global 'max_malloced' and not just the configuration
value MAX_MALLLOCED (Bug #0000069).
29-Jun-2004 (Lars Duening) (3.3.567)
- (comm.c) Improved the check for input_to() bitflags on an object with
telnet disabled so that only changes in the mode are warned about.
21-Jun-2004 (Lars Duening) (3.3.566)
- (xalloc) The memory reserves were allocated with xalloc(), but freed
with mem_free() - not good (reported by Heiko).
- (mstrings) Corrected a compiler error (thanks, Ralph!)
14-Jun-2004 (Lars Duening) (3.3.565)
- (doc/) Corrected a number of German manpages.
- (comm.c) net_connect() didn't compile with IPv6 (reported by Fini).
- (mstrings, object.c) Contradicting the documentation, save_object()
did not strip a trailing '.c' from the given filename (reported by
Niflheim@Unitopia) (Bug #00000067).
30-May-2004 (Lars Duening) (3.3.564)
- (interpret.c) Calling privilege_violation() with only three arguments
accidentally instructed the interpreter to pass four (reported
by Ralph).
- (simulate.c) limited() accidentally removed all arguments for the
closure to execute.
30-May-2004 (Lars Duening) (3.3.563)
- (smalloc.c) When using PThreads, don't request memory via sbrk() - on
Linux systems this leads to corrupted memory.
- (simulate) Added a new runtime limit LIMIT_COST (f-010320).
- (interpret, simulate) For limited() and set_limits() the limit
values are passed to the privilege_violation call (f-020131-0).
28-May-2004 (Lars Duening) (3.3.562)
- (interpret.c, port.h, util/indent/indent_globs.h) Adapted for gcc 3.4.0
(thanks, Ralph!).
- (mud/lp-245) Removed 'missing return value' warnings.
26-May-2004 (Lars Duening) (3.3.561)
- (prolang.y) The 'public shadows private' warning now checks only
for genuinely private functions, not merely hidden ones. This should
make the warning more accurate.
25-May-2004 (Lars Duening) (3.3.560)
- (prolang.y, interpret.c, simulate, string_spec, closure.c) Added
modifier 'reserve' to the catch() instruction in order to
specify the reserved amount of eval ticks at runtime (suggested
by Menaures).
24-May-2004 (Lars Duening) (3.3.559)
- (prolang.y) The compiler emits warnings if the functions defined by
two inherits collide in their visibility. If this produces too
much output, we will have to control this by a pragma. (suggested
by Bardioc).
- (simulate.c) If a catch() doesn't have enough eval time left
(less than CATCH_EVAL_COST), this is thrown as an error from inside
the catch instead of causing the catch to return 0. (suggested
by Menaures).
- (efuns.c) Removed compiler warnings (thanks, Guandalug!)
23-May-2004 (Lars Duening) (3.3.558)
- (object.c) When restoring structs and the saved data is longer than
the struct, make sure that the extra values are skipped in the
data.
23-May-2004 (Lars Duening) (3.3.557)
- (configure) Corrected a typo in the --with-udp-port option (thanks,
LynX).
- (object.c) When restoring structs, the sizes no longer need to match -
the driver restores as many members by position as possible.
23-May-2004 (Lars Duening) (3.3.556)
- (efuns, func_spec) The efuns member() and rmember() can take a
start position.
22-May-2004 (Lars Duening) (3.3.555)
- (smalloc.c) With USE_AVL_FREELIST, the AVL tree could develop cycles -
corrected that (reported by Ralph).
21-May-2004 (Lars Duening) (3.3.554)
- (func_spec, object, parse.c) The result of efun deep_inventory()
can be restricted to a certain depth (suggested by Urv).
20-May-2004 (Lars Duening) (3.3.553)
- (config.h.in) Oops, the AVL change to smalloc (3.3.534) was never activated.
- (smalloc.c) Small block allocated directly from a freelist didn't set
the GC_FREE flag. As this flag doubles as M_DEFRAG flag, many
blocks were accidentally considered 'permanent'.
- (object.c) When writing save files, only the names of structs
will use the shared-string notation. Other strings are given
literally for better readability (suggested by Coogan).
19-May-2004 (Lars Duening) (3.3.552)
- (comm.c) The H_NOECHO hook is now called only if the target object
is not destructed.
- (etc/savefile-parse.pl) Fini provided a Perl script (actually long time
ago) which can read a LPMud savefile and recreate the data as
Perl datastructures.
18-May-2004 (Lars Duening) (3.3.551)
- (simulate, backend.c, string_spec) Runtime errors are now also passed
to the master function runtime_warning().
18-May-2004 (Lars Duening) (3.3.550)
- (efuns.c) Bah, forgot the 'MTRACE_ARG' to the call of
mstring_cvt_progname(), so the file didn't compile when MALLOC_TRACE
was enabled (reported by Ralph).
17-May-2004 (Lars Duening) (3.3.549)
- (efuns.c, closure) Efun get_type_info() can now return the name
of the defining program for a lfun or context closure (Bug #0000010).
- (configure) Removed double checks for stdint.h and inttypes.h .
- (wiz_list.c) During a GC, the references for the error filename
and message weren't cleared.
- (gcollect) In general, string references weren't cleared during the
GC (a holdover from when all strings were tabled).
16-May-2004 (Lars Duening) (3.3.548)
- (my-stdint.h) I checked for a subtly wrong define here, causing the
compilation to break on Linux (reported by Ralph).
- (configure, my-stdint.h) FreeBSD doesn't have stdint.h, but it
has inttypes.h which serves mostly the same purpose (reported by
Joseph).
15-May-2004 (Lars Duening) (3.3.547)
- (configure, my-stdint.h, sha1.h) Added a test for and a replacement
of the C99 include file stdint.h, which is required by the sha1
code (reported by Joseph).
14-May-2004 (Lars Duening) (3.3.546)
- (comm.c, simul_efun.c) Corrected compilation errors (thanks, Ralph!)
13-May-2004 (Lars Duening) (3.3.545)
- (comm.c, pkg-mccp) A MCCP connection can now be terminated by force from
the driver.
- (comm.c, gcollect.c ) USE_PTHREADS: The memory allocations/deallocations
for the background thread are done using malloc()/free().
- (configure, smalloc.c) USE_PTHREADS: With threads, smalloc no longer
attempts to replace malloc() and friends. This way we can
use smalloc() for main-thread allocations, and fall back on system
malloc() for sub-thread allocations. In extension, smalloc is again
the default allocator even if pthreads are enabled.
- (configure) If pthreads are not requested, don't add the lib to
link (but still check if it's available).
- (simul_efun, main.c, interpret.c) Corrected the re-load of the simul
efun object so that returning 0 from master::get_simul_efun() again
signals working without such an object.
12-May-2004 (Lars Duening) (3.3.544)
- (array.c) My apologies to all involved: I messed up the callback
handling for unique_array() in 3.3.39 (reported by Ralph and Urv).
11-May-2004 (Lars Duening) (3.3.543)
- (main.c, simul_efun.c) If the simul-efun object can't be reloaded at
runtime, don't terminate the driver (reported by Bardioc).
- (mregex.c) Corrected a memory leak when using PCRE (reported by Alwin).
10-May-2004 (Lars Duening) (3.3.542)
- (mstrings.c) Since the purpose of mstring_unshare() and mstring_dup()
is to create modifiable string copies, the .hash value is set
to 0 in the new strings.
- (doc/efun.de) Updated (thanks, Menaures!)
09-May-2004 (Lars Duening) (3.3.541)
- (mstrings) mstr_get_hash() macro now first checks if the hash has
already been computed before calling the slower mstring_get_hash()
function.
- (pkg-tls, comm, func_spec, gcollect.c) tls_init_connection() is now
able to set up the TLS connection in the background, optionally
calling a callback function once the attempt fails or succeeds
finally.
08-May-2004 (Lars Duening) (3.3.540)
- (make_func.y) Worked around a bug in the codegeneration on AIX 5.2 for
both Visual Age C 6 and gcc 2.9.
- (mapping.c) When looking up string keys, the code only checked if the
string was tabled, not if it was directly tabled.
- (mstrings) The hash of a string is now stored with the string data
and computed on demand. Especially for lookups of strings in the
string table this should give some advantages.
- (mregex.c, otable.c) Make use of new mstring hash functions.
- (interpret.c) When multiplying an array, string elements are now
longer made tabled.
06-May-2004 (Lars Duening) (3.3.539)
- (array.c) Using name-based callbacks for unique_array() crashed
the driver (reported by Ralph).
- (mstrings.c) Modified mstring_make_tabled() and mstring_table_inplace()
so that the strings are always tabled in-place (using indirectly
tabled strings if necessary). This allows to table a string without
allocating any extra memory.
- (interpret.c) Assigning or transferring a string no longer makes
the string tabled (that's what we have refcounts in them for).
- (comm.c, efuns.c, gcollect.c, interpret.c, simulate.c) Adapted to the
no-failure versions of mstring_make_tabled().
- (doc/concepts/inheritance) Shiny new doc from Lynx (thanks!).
02-May-2004 (Lars Duening) (3.3.538)
- (pkg-tls.c) tls_query_connection() returns FALSE on non-interactive
objects instead of raising an error (suggested by Lynx).
30-Apr-2004 (Lars Duening) (3.3.537)
- (lex, prolang.y) The pragma '(no_)warn_missing_return' controls whether
the driver checks for missing return statements or not; by default
the check is enable.
- (prolang.y) If the driver can detect at compile time that a return
statement is missing, a compile time warning is emitted and the
code uses the normal F_RETURN0 as default return.
- (prolang.y) Corrected compilation errors when NEW_INLINES was not
defined (Bug #0000056)
28-Apr-2004 (Lars Duening) (3.3.536)
- (etc/patch-o-matic, settings/forgottendreams) Updated with the latest
version (thanks, Andre!)
- (pkg-tls.c) The TLS handshake() is retried when it failed with
an E_AGAIN or E_INTERRUPTED for GnuTLS, or WANT_READ/WANT_WRITE
for OpenSSL (thanks, Fippo!) (Bug #0000054)
27-Apr-2004 (Lars Duening) (3.3.535)
- (strfuns.c) Efun convert_charset() crashed when given an empty
input string (reported by Ralph).
- (configure) When checking for iconv, the script now first checks
if -liconv is actually needed before looking for the libraries
(reported by Philipp).
- (configure) Made the test for non-const in parameter to iconv()
more reliable ... I hope (reported by Ralph).
27-Apr-2004 (Lars Duening) (3.3.534)
- (smalloc.c, config.h, efuns.c) If multiple large blocks of the same
size are freed, an AVL node is created just for the first one of these
blocks. The other blocks are held in a double-linked list hanging
off the AVL node. For now, this feature is activated by
the macro USE_AVL_FREELIST in config.h. Practive will show if
the ratio of free blocks to AVL nodes is large enough to make
this useful. (Bug #0000053)
27-Apr-2004 (Lars Duening) (3.3.533)
- (strfuns.c) Efun convert_charset(): The parameters to iconv_open() were
reversed.
- (smalloc.c) If esbrk() can allocated more memory than asked, the
difference is now returned in a pointer-argument instead of
a global variable - much easier to understand this way.
26-Apr-2004 (Lars Duening) (3.3.532)
- (actions.c) Added missing include.
- (configure) Corrected bison recognition under AIX/Visual Age 6.
- (configure) Test if iconv() takes a non-const char** as input string.
- (random.c) Adapted for AIX/Visual Age 6.
- (interpret.c) <int> -= <float> subtracted a random number (reported by
Acius).
- (efuns.c, port.h) Efun reverse() can bit-reverse integers.
- (etc/lpc.xml) Menaures provided a new version.
24-Apr-2004 (Lars Duening) (3.3.531)
- (smalloc.c) Corrected the permanent block allocation statistics.
- (func_spec) Deprecated efun make_shared_string().
- (func_spec, strfuns) New efun convert_charset() (thanks, Philip).
24-Apr-2004 (Lars Duening) (3.3.530)
- (xalloc.c, smalloc.c) Changed the memory dump output format so that all the
important information is on one line. Also increased the size of
the initial small chunk so that all the driver's own tables fit
into it.
24-Apr-2004 (Lars Duening) (3.3.529)
- (comm.c) Integrated Uwe's patch to open IPv6 connections with
net_connect() (thanks!).
- (efun.de/) A few more manpage translations.
- (func_spec, efuns) New efun reverse() (provided by Ralph, thanks!)
(f-000113-1, f-990714-7, f-990203-15)
23-Apr-2004 (Lars Duening) (3.3.528)
- (main.c) The standard strings are initialized earlier in the startup
process so that a memory error doesn't cause a coredump.
22-Apr-2004 (Lars Duening) (3.3.527)
- (efuns.c) Forgot an '#include <fcntl.h>'.
22-Apr-2004 (Lars Duening) (3.3.526)
- (smalloc.c, xalloc.c, efuns.c) debug_info(DINFO_DUMP, "memory")
dumps a list of all allocated memory blocks into the file
<mudlib>/MEMORY_DUMP, if the allocator supports this.
22-Apr-2004 (Lars Duening) (3.3.525)
- (sha1) The files were still in DOS fileformat, which causes some
compilers to choke on the multi-line macro definitions.
- (backend.c) Active objects were never cleant up.
- (gcollect.c) During object cleanup, mappings with just one reference
left are not cleant up, as they will be freed immediately.
20-Apr-2004 (Lars Duening) (3.3.524)
- (configure) The MySQL libraries are now also search in
/usr/local/lib/mysql/lib (can happen on older installations on Mac
OS-X). Also, when the libraries were found in /usr/local/lib, the
script still added /usr/local/mysql/lib to the link command.
- (mudlib/sys/lpctypes.h) Corrected a typo.
18-Apr-2004 (Lars Duening) (3.3.523)
- (func_spec, sha1, efuns) New efun sha1() (provided by Fippo -
thanks!).
- (func_spec, files.c) Efun write_file() can now be instructed to
delete the file first (suggested by Pulami).
18-Apr-2004 (Lars Duening) (3.3.522)
- (interpret.c) F_RETURN now takes care to undo a pending SAVE_ARG_FRAME.
This situation can happen in a closure like ({#'sprintf, "%O",
({#'return, 1 }) }) (reported by Risky).
18-Apr-2004 (Lars Duening) (3.3.521)
- (prolang.y, func_spec, interpret.c) The default return inserted for
value returning functions (in case the programmer forgets about
it) now generates a runtime warning so that such code can be found
and corrected. This applies only for functions with specified return
type - old type functions don't generate a warning (suggested by
Heiko).
15-Apr-2004 (Lars Duening) (3.3.520)
- (func_spec, array, simulate) Efun unique_array() can now use
a closure as separator function, and also pass extra arguments
(suggested by Shinarae).
14-Apr-2004 (Lars Duening) (3.3.519)
- (prolang.y) I had to restrict '&(struct->member)' to a single level
of member lookup because the compiler generated invalid code.
13-Apr-2004 (Lars Duening) (3.3.518)
- (sprintf.c) Made the code portable to non-32-bit machines.
- (test/t-040413) Added a testcase for two struct lookup issues.
13-Apr-2004 (Lars Duening) (3.3.517)
- (sprintf.c) Format '%b' to print a number in binary notation (supplied
by Ralph - thanks!).
13-Apr-2004 (Lars Duening) (3.3.516)
- (func_spec, prolang.y, interpret.c) I had to back out the recent change
as it interfered with the use of bitflags. We need a proper unsigned
type for this kind of thing.
12-Apr-2004 (Lars Duening) (3.3.515)
- (mud/heaven7, settings/heaven7) Heaven7 v4 runs natively on LDMud 3.2 .
- (func_spec, prolang.y, interpret.c) Constant integer numbers exceeding the
allowed range cause runtime errors (reported by Ralph).
11-Apr-2004 (Lars Duening) (3.3.514)
- (svalue.h) Reserved CLOSURE typecode 1 (used to be CLOSURE_ALIEN_LFUN) for
future use, so that the other closure typecode have the same value as
in 3.2 (suggested by Sebastion).
- (mudlib/sys/lpctypes.h) Added symbolic defines for the closure typecodes.
10-Apr-2004 (Lars Duening) (3.3.513)
- (comm.c) Corrected a compilation error when TELNET_DEBUG is defined
(thanks, Tobias).
- (comm.c) Using input_to() without a command_giver crashed the
driver.
- (erq/erq.c, xerq/lookup.c) Well, TRY_AGAIN is a h_errno result,
not errno (thanks, Tobias).
- (xptmalloc.c) Under *BSD when using pthreads and GC support, malloc()
is used before the pthread structures are available. For this
reason, REPLACE_MALLOC is disabled under *BSD (for simplicity in
all cases).
09-Apr-2004 (Lars Duening) (3.3.512)
- (efuns.c) The cost calculation for efun clones() forgot to take the
number of checked objects into account.
- (configure, sprintf.c) trunc() is a C-99 library function; if not
available, the driver uses ceil()/floor() instead.
- (mudlib/dns_resolve.c) Example simul-efun for doing non-blocking
DNS lookups (thanks, Tobias & Arne!)
- (doc/efun.de) Added the german efun manpages from Unitopia (thanks,
Tiberian!)
- (util/erq/erq.c) Corrected the ERQ_LOOKUP so that the passed-in hostnames
are properly null-terminated (thanks, LynX).
- (util/erq/xerq.c) ERQ_LOOKUPs are tried again only if the DNS indicates
that it is useful.
06-Apr-2004 (Lars Duening) (3.3.511)
- (comm.c) With telnet disabled, an input_to() can still pretend to
switch from line- to charmode.
04-Apr-2004 (Lars Duening)
- (erq.c) Retry name-lookups only if the DNS subsystem said so (thanks,
Tobias!).
03-Apr-2004 (Lars Duening) (3.3.510)
- (func_spec, comm, string_spec) New efun enable_telnet() to disable/enable
telnet support.
03-Apr-2004 (Lars Duening) (3.3.509)
- (object.c) function_exists() and variable_exists() now check if the
object is destructed, instead of crashing (Bug #0000038).
- (files.c, backend.c, object.c) Added missing include for SunOS 4.1
(reported by Coogan).
- (configure, main.c) strtoul() is not available on the older machines,
this is now checked by configure (reported by Coogan).
- (object.c) If H_RESET/H_CREATE_* are defined by name, static functions
are found as well (suggested by Daniel).
03-Apr-2004 (Lars Duening) (3.3.508)
- (object.c) restore_value() now checks for and rejects extraneous
characters after the '\n' delimiting the value string (Bug #0000039).
- (prolang.y) Casts to type 'mixed' are exempted from generating
an "empty cast" warning (Bug #0000041).
- (configure) The configuration now checks for libnsl as standard
system library - it is needed for ERQ on Solaris (Bug #0000012).
01-Apr-2004 (Lars Duening) (3.3.507)
- (prolang.y, interpret.c) Implemented <mapping> &= <mapping>,
<mapping> &= <vector> (Bug #0000042).
- (interpret.c) get_line_number(): Program names in the traceback
can be arbitrarily long (Bug #0000040).
31-Mar-2004 (Lars Duening) (3.3.506)
- (prolang.y) Corrected range check regarding short integers (thanks,
Gnomi).
- (comm.c, pkg-mccp.c, mregex.c, structs.c) Removed warnings (thanks,
Andre!).
30-Mar-2004 (Lars Duening) (3.3.505)
- (func_spec) The result type of m_entry() was specified as 'mapping'
instead of the correct 'mixed *' (thanks, Heiko!).
- (random.c) Updated the Mersenne twister to the version with improved
initialization (thanks, Fini, for the link).
27-Mar-2004 (Lars Duening) (3.3.504)
- (mstrings, interpret.c) Extended the string-appending scheme
to addition of numbers to strings.
- (ed.c) The 'Q'/'q' commands no longer clear the buffer before
checking if the command was legal (Bug #0000046).
- (ed.c) Corrected the doprnt() function so that the current line
is never out of range (this could happen when giving 'Z' while
at the end of the file). (Bug #0000045)
27-Mar-2004 (Lars Duening) (3.3.503)
- (strfuns, simulate.c) Added a function to make a c-string copy
of a strbuf.
- (mempools.c) Reduced the ideal size of a pool block to 128 bytes -
hopefully this reduces some of the fragmentation issues.
- (mstrings, interpret.c) When adding strings (operators '+' and
'+='), the driver tries to extend the left-hand string when
possible, instead of allocating a new string. When creating
large strings, this hopefully improves the reduces the allocations
of new string buffers.
- (interpret.c) inl_transfer_svalue() no longer makes untabled
strings tabled. Originally the driver did this for volatile strings
at this point, which no longer exist.
23-Mar-2004 (Lars Duening) (3.3.502)
- (actions.c) If the H_COMMAND lfun is not found in an object, the
driver now throws an error instead of crashing (reported by Urv).
22-Mar-2004 (Lars Duening) (3.3.501)
- (prolang.y) Corrected a crasher when printing type of incomplete
structures (as they are used to store the efun type specifications)
(thanks, Alwin!) (Bug #0000043)
24-Feb-2004 (Lars Duening) (3.3.500)
- (xerq/socket.c) When sending data over a congested socket, the
queued data included the last successfully sent bytes
(thanks, Fantom!).
22-Feb-2004 (Lars Duening) (3.3.499)
- (comm) The net_connect() handling wasn't prepared for errors during the
LPC logon, occasionally re-trying the logon endlessly (reported
by Dafire).
19-Dec-2003 (Lars Duening) (3.3.498)
- (comm) When a connection can't be opened immediately with net_connect(),
the socket was closed prematurely (reported by LynX).
14-Dec-2003 (Lars Duening) (3.3.497)
- (comm) When opening a connection with net_connect(), printing of
the prompt clobbered the current_object, causing a crash.
21-Nov-2003 (Lars Duening) (3.3.496)
- (comm) Added new efun net_connect() (thanks, LynX!)
- (object.c, sys/functionlist.h) Efun variable_list() didn't properly
filter for static variables.
18-Nov-2003 (Lars Duening) (3.3.495)
- (mudlib/telnetneg.c, xerq/lpc/socketd.c) New versions from Fiona (thanks!)
- (sprintf.c) When printing floats with %O/%Q, they are always printed
with a decimal point (suggested by Fiona).
30-Oct-2003 (Lars Duening) (3.3.494)
- (prolang.y) When creating a foreach() instruction, don't get confused
by visibility flags in the variable type. Before, a 'varargs mixed *'
function parameter was errorneously recognized as reference
(reported by Alwin and Fiona).
- (prolang.y) When removing an unnecessary F_SAVE_ARG_FRAME from a
functioncall, also update the last_expression value. Before,
a F_CONST0 pushed in place of a void-functions return value
was never optimized out.
17-Oct-2003 (Lars Duening) (3.3.493)
- (comm.c) Efun query_ip_number(): the return of the full socket
address in a reference argument didn't work (thanks, Nostradamus).
- (configure) More corrections to the detection of -lcrypto and -lz
(reported by Jaroslaw).
15-Oct-2003 (Lars Duening) (3.3.492)
- (configure) Made sure that -lz always follows the -lmysqlclient,
as some system apparently can't resolve all backward references
(reported by Alwin).
02-Oct-2003 (Lars Duening)
- (comm.c, mempools.c, ptmalloc, xalloc.c) Removed signed/unsigned
compiler warnings (thanks, Ralph).
- (pkg-odbc, p-031002) Added, but not yet processed (thanks, Robert!).
30-Sep-2003 (Lars Duening) (3.3.491)
- (comm.c) The maxNumCmds setting was defaulted to 0 instead of -1
(reported by Bardioc).
- (comm.c, master_skeleton.c) Officially documented that a new
interactive connection is bound to the master at the time
of master::connect(), and adjusted the set_max_commands
manpage accordingly.
- (lex.c) The macros __RESET_TIME__ and __CLEANUP_TIME__ always used
the configured values, ignoring commandline overrides (reported
by Ralph).
- (interpret.c, func_spec) New efun master() to return the master object.
28-Sep-2003 (Lars Duening) (3.3.490)
- (comm.c) Removed a crasher from set_max_commands() (thanks, Ralph!).
27-Sep-2003 (Lars Duening) (3.3.489)
- (autoconf) Renamed the option enable-use-array-calls to
enable-lpc-array-calls, as it's a language option and not a package.
27-Sep-2003 (Lars Duening) (3.3.488)
- (efuns.c) Added a third argument to debug_info(DINFO_OBJLIST) to return
multiple objects.
- (comm, func_spec) New efuns set_max_commands(), get_max_commands()
to control the number of commands allowed per second on a
per-connection basis.
- (svalue.h) Added macro put_float() to store floats into a svalue.
- (lex, prolang.y) Pragma (no_)warn_empty_casts allows to turn off
the warnings about ineffective casts.
- (etc/lpc.vim) LPC syntax highlighting for vim (submitted by Coogan).
- (autoconf, interpret.c, main.c, lex.c) The call_other() on arrays of
objects is now configurable; if enabled, __LPC_ARRAY_CALLS__ is
defined.
- (mudlib/sys/commands.h) Added defines for the query_action() bitflags.
- (array.c, mapping.c, pkg-alists.c, sprintf.c, xalloc.c, prolang.y)
Removed a couple of signed/unsigned warnings (thanks, Ralph!).
- (efuns.c) to_array(string) now treats the string characters as unsigned
(reported by Fiona).
27-Sep-2003 (Lars Duening) (3.3.487)
- (prolang.y) Corrected some subtleties in the lfun/efun classification
of functions, revealed by the recent change.
- (simul_efun.c) The __INIT() function is no longer visible as simul-efun.
25-Sep-2003 (Lars Duening) (3.3.486)
- (prolang.y, lex) The driver crashed when a private lfun shadowing
a public sefun was virtually inherited twice in parallel, because
the public sefun inhibited a proper cross-definition of the second
lfun instance. The problem was in the either-or assignment of an
identifier to either be an lfun or a (s)efun/global var (t-030925).
- (mapping.c) When walking over a mapping of width 1, the hash part
was not protected; thus deletions from the mapping from within the
walk_mapping callback could cause walk_mapping() to pass invalid
pointers to the callback on later iterations (reported by Bardioc).
- (comm, func_spec) Passing 0 as argument to
set_{combine,connection}_charset() re-establishes the default charset.
- (comm, func_spec) New efuns get_combine_charset() and
get_connection_charset().
- (comm) Experimental: limited the number of commands accepted per
connection to 10 per second - this is meant as a safety limit for
muds making heavy use of charmode connections. If it works out,
the feature will be fully fleshed out with commandline arguments
and everything (Mantis #0000009).
12-Sep-2003 (Lars Duening) (3.3.485)
- (sprintf.c) Printing a 0-member struct with '%O' crashed the driver
(reported by Nostradamus).
02-Sep-2003 (Lars Duening) (3.3.484)
- (prolang.y) When creating a local lvalue, the compiler didn't properly
check if it's a real local or a context value, causing
'map( arr, (: mm[$1]; :) );' to resolve 'mm' as local value (reported
by Zonk).
24-Aug-2003 (Lars Duening) (3.3.483)
- (lex.c) Removed a crasher.
- (configure) Improved the mySQL/PostgreSQL recognition: on some machines,
/usr/local/include is not in the standard search path :-(
21-Aug-2003 (Lars Duening) (3.3.482)
- (configure) Improved the PostgreSQL recognition.
- (make_func.y, actions.c, array.c, backend.c, bitstrings.c, comm.c,
efuns.c, files.c, hash.c, interpret.c, lex.c, main.c, mapping.c,
mempools.c, mstrings.c, object.c, prolang.y, parse.c, pkg-pgsql.c,
simulate.c, sprintf.c, smalloc.c, xalloc.c) Removed signed/unsigned
compiler warnings.
20-Aug-2003 (Lars Duening) (3.3.481)
- (configure, pkg-mysql.h, pkg-pgsql.h) If mySQL/PostgreSQL are configured
but not existant, the compilation will fail with a suitable error
message. Also the configure script tries harder to not let this happen
(Mantis #0000013).
19-Aug-2003 (Lars Duening) (3.3.480)
- (lex, prolang.y, files.c, simulate.c, backend.c, closure.c) Redefinition
of LPC preprocessor macros now list the file and line of the original
definition (suggest by Bardioc).
14-Aug-2003 (Lars Duening) (3.3.479)
- (smalloc.c, debug_info.h) Added small block defragmentation
statistics.
14-Aug-2003 (Lars Duening) (3.3.478)
- (pkg-tls, comm, md5, configure) Added the OpenSSL support. It's probably
buggy as heck as I had to copy&paste from OpenSSL demo programs due
to lack of documentation.
13-Aug-2003 (Lars Duening) (3.3.477)
- (pkg-tls) Added the program initialisation/de-initialisation code for
OpenSSL.
09-Aug-2003 (Lars Duening) (3.3.476)
- (configure) The configuration script now looks for OpenSSL before
GnuTLS. However, TLS support using OpenSSL is not implemented yet.
09-Aug-2003 (Lars Duening) (3.3.475)
- (main.c, pkg-tls) The x509 key and certfile can now be specifed
on the commandline with '--tls-key' and '--tls-cert'.
08-Aug-2003 (Lars Duening) (3.3.474)
- (pkg-tls.c, comm.c) Corrected compilation errors in the TLS code
(I didn't have GnuTLS installed before, so I didn't notice).
08-Aug-2003 (Lars Duening) (3.3.473)
- (lex.c) Symbol __PTHREADS__ is defined if the driver is compiled
for pthreads (suggested by Gawain).
- (configure, pkg-tls) Added TLS support (using GnuTLS) - thanks,
Gawain!
07-Aug-2003 (Lars Duening) (3.3.472)
- (doc/) Corrected a number of typos (thanks, Casey!)
- (object.c) The efun variable_list() can now return variable values
as well (thanks, Casey!).
07-Aug-2003 (Lars Duening) (3.3.471)
- (configure, pkg-mysql, main.c) Improved the recognition of mySQL when
there's more than one mySQL installation. Additionally the pkg-mysql
checks that the mysqlclient library is consistent with the header
files (reported by Craig Venz).
05-Jul-2003 (Lars Duening) (3.3.470)
- (smalloc.c) Reduced the computational overhead of the small block
defragmentation: since only newly freed blocks offer opportunities
for defragmentation, only those are checked.
- (object.c) Saving an object in the old format ('0') still used the
shared value syntax for strings (reported by Bardioc).
31-Jul-2003 (Lars Duening) (3.3.469)
- (smalloc.c) Splitting of a block from a larger free list failed
to preserve the PREV_BLOCK flag in the returned block, causing
the defragmentation to malfunction on occasion (Mantis #0000007)
29-Jul-2003 (Lars Duening) (3.3.468)
- (smalloc.c) The small-block defragmentation clobbered an important
flag in some blocks, causing the driver to crash (reported by Bardioc).
- (smalloc.c) Reduced the amount of freelist-linking done for
non-defragmentable blocks.
28-Jul-2003 (Lars Duening) (3.3.467)
- (prolang.y) If a pragma requires a function return type, the error
message now names the active pragma in question instead of always
'strict_types' (Mantis #0000003)
- (comm.c) In charmode, CR and LF are treated as normal data
characters (Mantis #0000002).
26-Jul-2003 (Lars Duening) (3.3.466)
- (mapping.c) Taking a cue from 3.2.10-594, the number of times a mapping
is checked for destructed elements has been reduced. This was less of
a problem than in 3.2.10, but still occured far too often,
- (mapping.c) The mapping compaction criterium has been extended to
guarantee a compaction after 2 * TIME_TO_COMPACT seconds idle time.
25-Jul-2003 (Lars Duening) (3.3.465)
- (mudlib/dhrystone.c) The time measurement was off by factor 10.
- (smalloc.c) Implemented a lazy defragmentation scheme for the
free small blocks.
24-Jul-2003 (Lars Duening) (3.3.464)
- (configure) Improved the detection of libcrypt and libcrypto.
- (bytecode.h, hosts/crypt.c) Added a number of macros to deal with 64-bit
machines (untested).
23-Jul-2003 (Lars Duening) (3.3.463)
- (sysmalloc.c, ptmalloc/malloc.c) Corrected compilation errors (reported by
Tomba).
22-Jul-2003 (Lars Duening)
- (object.c) Cleaned up the code in restore_object() a wee bit.
21-Jul-2003 (Lars Duening) (3.3.462)
- (interpret.c) The -= operator didn't work when subtracting an int
from an int: a missing break caused it to flag a non-existant
argument error.
17-Jul-2003 (Lars Duening) (3.3.461)
- (prolang.y) Made the cast checks more informative.
17-Jul-2003 (Lars Duening) (3.3.460)
- (interpret.c) The operators -=, /= and *= can now operate on
<int> x <float> values, yielding a <float> result.
- (prolang.y) Casts with no effect generate a warning.
17-Jul-2003 (Lars Duening) (3.3.459)
- (i-svalue_cmp.h) When comparing closures for equality, the result was
reveresed (reported by Fantom).
- (array.c, interpret.c) Replaced uses of closure_cmp() with closure_eq()
where appropriate.
10-Jul-2003 (Lars Duening) (3.3.458)
- (interpret.c) When the value stack overflowed during a secure_apply(),
the secure_apply_error() routine failed to notice that the stack
elements had already been cleared out (reported by Bardioc).
27-Jun-2003 (Lars Duening) (3.3.457)
- (xptmalloc.c) Added a heap_start variable so that assert_stack_gap()
will compile (reported by Dafire).
- (ptmalloc) Added Gawain's latest changes - thanks!
26-Jun-2003 (Lars Duening)
- (interpret.c) Added compile-time check to make sure that MAX_USER_TRACE
is not larger than MAX_TRACE.
25-Jun-2003 (Lars Duening) (3.3.456)
- (xalloc.c) On HP-UX machines, the stack is above the heap and is also
growing upwards, which the heap/stack check didn't expect. I reworked
the code to be more generic (reported by Rainer).
- (lex.c, interpret.c) Characters with the 8th bit set are now uniformly
treated as positive by the lexer and indexing operations (reported by
Oskar).
- (lex.c) Added macro __MAX_MALLOC__ to reflect the MAX_MALLOCED
parameter (suggested by Coogan).
18-May-2003 (Lars Duening) (3.3.455)
- (sprintf.c) Removed a memory leak in efun printf() (reported by Dafire).
07-May-2003 (Lars Duening) (3.3.454)
- (simulate.c) The error() routine now takes care to zero out all
pointer variables after freeing the referenced data. This way, if
a recursive error occurs before the new reference is stored the
driver won't try to free the same references again (reported by
Freaky).
05-May-2003 (Lars Duening) (3.3.453)
- (lex.c) Ooops, I forgot that I had commented out the strong type
pragmas when I experimented with an older mudlib (thanks, Ralph).
- (ptmalloc/thread-m.h) The constraints for one asm statement operand
were wrong (reported by Bardioc).
- (object.c) Made restore_xxx() even more robust towards CRLFs (thanks,
Holger).
03-May-2003 (Lars Duening) (3.3.452)
- (simulate, interpret, func_spec, prolang.y) Added the new modifier
'publish' to the catch() directive to have it call
master::runtime_error() when an error occurs (suggested by
Menaures).
03-May-2003 (Lars Duening) (3.3.451)
- (comm.c) When a pthread was cancelled, the flushing of the pending
data happened after the socket was already shut down. Reason was that
the threads were 'detached' upon creation, disabling the ability
of the parent thread to wait for their completion (reported by Urv).
- (object.c) The restore_svalue() routine now accepts a CR preceeding
a LF as delimiter.
30-Apr-2003 (Lars Duening) (3.3.450)
- (ed.c) Only consecutive 'z'/'Z' commands do not re-print the current line;
a 'z'/'Z' after a different command does (suggested by Elric).
- (comm) When using PThreads, destructing an interactive object now
flushes all remaining pending data to the socket (suggested by Urv).
Additionally, the main thread waits properly for the writer thread to
terminate.
- (comm.c) When not using MCCP but PThreads, all outputs were doubled.
29-Apr-2003 (Lars Duening) (3.3.449)
- (sprintf.c) When printing arrays with '%O', the size was given
one too small.
- (mregex.c) PCRE: The string arguments passed to pcre_exec() were wrong,
making repeated replacements within on string dangerous (e.g. in ed
'749,$s!arg!strength!gp') (reported by Elric).
24-Apr-2003 (Lars Duening) (3.3.448)
- (interpret.c) If during a call of the type 'funcall(lfun-closure)' the
object holding the closure was destructed and the closure deallocated,
int_call_lambda() still read the now-invalid lambda structure after
the actual call. This could lead to an inconsistency in the
control stack, depending on the memory contents (reported by Bardioc).
22-Apr-2003 (Lars Duening) (3.3.447)
- (pkg-mccp, comm, gcollect.c, configure) Added MCCP support (thanks,
Dafire!) (p-011012, p-020810-1).
21-Apr-2003 (Lars Duening) (3.3.446)
- (pkg-pgsql.c) Corrected a crasher during a GC.
- (smalloc.c) Corrected the small-free-block statistics.
19-Apr-2003 (Lars Duening) (3.3.445)
- (pkg-pgsql, configure, other files) Added PostgreSQL implementation
based on the code donated by Ctx (thanks!) (f-011229-0).
13-Apr-2003 (Lars Duening) (3.3.444)
- (smalloc.c) Removed compilation warnings.
13-Apr-2003 (Lars Duening) (3.3.443)
- (func_spec, object) The efuns save_value() and save_object() can now
create savefiles in the old format as well.
12-Apr-2003 (Lars Duening) (3.3.442)
- (xalloc.c) Corrected a compilation error when MALLOC_TRACE was not
defined.
12-Apr-2003 (Lars Duening) (3.3.441)
- (smalloc.c) Adjacent free small blocks are now merged automatically
as soon as they are detected. This reduces the mem_consolidation()
call to detecting and freeing totally unused small chunks.
- (xalloc.c) The block dump of lost blocks now prints a proper hexdump
instead of just dumping the data as-is.
11-Apr-2003 (Lars Duening) (3.3.440)
- (smalloc.c) A bit of code cleanup; and in preparation for the planned
automatic small block defragmentation introduced 'free' flags for
small blocks and a minimum payload size.
09-Apr-2003 (Lars Duening) (3.3.439)
- (efuns.c, strfuns, func_spec) Efuns filter() and map() can be used on
strings.
09-Apr-2003 (Lars Duening) (3.3.438)
- (heartbeat.c) Removed the pooled allocation of heartbeat structures:
Muds have spikes of high callout usage, but a low usage over
the longterm average, so most of the pooled structures are not
used. This more than makes up for any malloc overhead saved
by the pooled allocation.
- (heartbeat.c) Errors in a heartbeat execution now longer aborts
the whole heartbeat cycle (suggested by Baba).
- (efuns.c, main, mudlib/sys/debug_info.h) The boot time is now
available through debug_info(DINFO_DATA, DID_STATUS).
- (wizlist) The wizlist now accounts the evalcost split into
ticks and gigaticks, to be able to handle long uptimes, and also
offer a non-decaying total sum of the evalcosts (suggested by
Baba).
07-Apr-2003 (Lars Duening) (3.3.437)
- (mud/lp-245) Adapted the set_this_object() usage in the master.
- (actions.c) Efun remove_action() can now remove all actions defined
by an object (suggested by Menaures).
04-Apr-2003 (Lars Duening) (3.3.436)
- (structs.c) When remove_unreferenced_struct() freed the structs, it
forgot to properly mark the memory blocks as 'allocated', so that
the final sweep phase of the GC tried to free them again (reported
by Nostradamus).
30-Mar-2003 (Lars Duening) (3.3.435)
- (comm.c) The driver now logs the pathname of the ERQ executable
it attempts to start.
29-Mar-2003 (Lars Duening) (3.3.434)
- (config.h.in) The options MALLOC_CHECK and MALLOC_SBRK got mixed up.
- (gcollect.c) The cleanup code didn't remove the program from the swap
when it zeroed out a reference to a destructed blueprint. Later GCs
then followed this invalid pointer.
27-Mar-2003 (Lars Duening) (3.3.433)
- (simulate.c, mapping) Since there is no longer a list of dirty mappings,
and since the GC can handle dirty mappings, it is no longer feasible
to keep an accurate count.
- (efuns.c) to_struct() can now convert mappings to structs.
- (mapping.c) mkmapping() can now convert structs to mappings.
26-Mar-2003 (Lars Duening) (3.3.432)
- (prolang.y) Constrained the switch() grammar to accept just blocks
as body, not statements (reported by Menaures).
- (comm.c) After removing a pending input_to, the proper noecho
state is restored (provided by Ctx).
25-Mar-2003 (Lars Duening) (3.3.431)
- (port, simulate.c) Since memmem() is a GNU/Linux extension and buggy
up to glibc 2.0, the driver now uses its own replacement all the
time. But I adjusted the argument order to the one used by the
correct Linux function (reported by Fiona).
- (interpret.c) Function calls by address and global variable accesses
now check if a set_this_object() is in effect.
24-Mar-2003 (Lars Duening) (3.3.430)
- (prolang.y) Assignment to struct members caused a fatal error if
the struct did not have the named member. The problem was that
in such a case an invalid type was recorded for the result (reported by
Dafire).
21-Mar-2003 (Lars Duening) (3.3.429)
- (object.c) Shared strings are now saved in the <n> notation as well;
this is mostly beneficial for saving endless repetitions of the
same struct name (suggested by Bardioc).
20-Mar-2003 (Lars Duening) (3.3.428)
- (object.c) Restoring the efun closure "#e:," confused the
savefile parser (thanks, Risky).
- (func_spec, efuns, mstrings) New efun strrstr().
- (mapping, prolang.y) Operator '&' can now intersect mappings with
other mappings and arrays.
- (func_spec, mapping) New efun m_entry() to return all values for
an entry at once.
19-Mar-2003 (Lars Duening) (3.3.427)
- (sprintf.c, closure) Modifier '#' used for '%O' and '%Q' produces
output in a compact format (suggested by Menaures).
- (func_spec, efuns) New efun rmember().
19-Mar-2003 (Lars Duening) (3.3.426)
- (structs.c, object.c) Saving and restoring struct now also saves
the defining program's name, so that external restore modules
can restore the values (reported by Bardioc).
17-Mar-2003 (Lars Duening) (3.3.425)
- (backend.c, gcollect.c) Corrections to the cleanup code: removed an
interaction between the cleanup code and the swapper, which caused an
incomplete cleanup; made sure that dirty mappings are compacted just
once; and made sure that the backend cleanup code actually cycles
through the object list.
- (call_out.c) Removed a memory leak in remove_call_out()/find_call_out().
17-Mar-2003 (Lars Duening) (3.3.424)
- (doc/master) Added missing manpages for the parse_command() support
(reported by Zonk).
- (main, simulate.c, configure) New commandline option '--filename-spaces'
to allow space characters in filenames (default is to disallow them).
- (object.c) Shared variable closures were saved without the '<num>=' header
(reported by Menaures and Fiona).
17-Mar-2003 (Lars Duening) (3.3.423)
- (mapping.c) Removed a memory leak.
15-Mar-2003 (Lars Duening) (3.3.422)
- (gcollect.c) The NEW_CLEANUP code treated the driver hooks like other
svalues, which was bad because it caused lambda-closure hooks bound
to destructed objects to disappear. Since these closures can be re-bound
on the fly, the cleanup code now does exactly that (reported by
Nostradamus and Bardioc).
14-Mar-2003 (Lars Duening) (3.3.421)
- (driver.h, smalloc.c) Removed a build problem when MALLOC_CHECK
was not defined, but MALLOC_TRACE was (reported by Nostradamus).
13-Mar-2003 (Lars Duening) (3.3.420)
- (xalloc.c, smalloc.c, configure) New configuration option
'--enable-malloc-sbrk' to selectively allow the memory allocator to use
sbrk() instead of malloc() where available (default is to allow sbrk()).
The idea is to circumvent limitations some system put on sbrk().
(suggested by Tomba)
12-Mar-2003 (Lars Duening) (3.3.419)
- (mapping.c, gcollect.c) The mapping GC forgot to mark the map-chain
blocks as referenced (reported by Bardioc).
11-Mar-2003 (Lars Duening) (3.3.418)
- (structs.c) Removed a crasher caused by two uninitialized variables.
- (mappings, gcollect.c) The GC can now collect mappings with hash
parts.
- (ptmalloc.c) More locking code - these should cover almost all
cases (thanks, Gawain).
10-Mar-2003 (Lars Duening) (3.3.417)
- (prolang.y) Corrected the error handling when a struct member was
duplicated and clashed with an inherited member (reported by
Guandalug).
- (prolang.y, structs, hash, efuns.c, interpret.c, sprintf.c)
When a struct-defining program is recompiled, the compiler
tries to reactivate the struct type objects if possible.
08-Mar-2003 (Lars Duening) (3.3.416)
- (swap.c, mapping) The swapper got out of sync when swapping mappings
with destructed objects as keys. So far it was not a problem because
mappings got compacted faster than they were swapped, and the swapper
already refused to swap mappings with objects/closures used as keys
in the condensed part. But with the new mapping compaction strategy
a more thorough test became necessary.
07-Mar-2003 (Lars Duening) (3.3.415)
- (configure) New configuration option '--with-optimize' to select
the optimization level in the generated Makefile: no, low,
med, or high.
- (call_out.c) Removed the pooled allocation of callout structures:
Muds have spikes of high callout usage, but a low usage over
the longterm average, so most of the pooled structures are not
used. This more than makes up for any malloc overhead saved
by the pooled allocation.
- (swap.c) Added sanity checks to the variable swapper.
06-Mar-2003 (Lars Duening) (3.3.414)
- (dumpstat.c) Corrected build warnings.
- (mempools, lex.c) Cosmetic changes.
- (mapping.c) Additional condition for mapping compaction: the number
of entries in the hash part is equal to or exceeds the number
of non-deleted condensed entries.
06-Mar-2003 (Lars Duening) (3.3.413)
- (mapping, gcollect, backend) The compaction of dirty mappings is now
part of the object cleanup process. This needs some careful handling,
but simplifies the mapping code.
05-Mar-2003 (Lars Duening) (3.3.412)
- (mempools, alloca.c, array.c, object.c, lex.c, ptrtable.c) The user
space of a mempool block is now restricted to 256 bytes, to reduce
fragmentation issues in the large block heap.
05-Mar-2003 (Lars Duening) (3.3.411)
- (gcollect.c, object.c) Inserted checks so that the driver doesn't try
to access the non-existing name of the default wizlist entry (in
particular the GC) (reported by Bardioc).
03-Mar-2003 (Lars Duening) (3.3.410)
- (mapping, backend.c, gcollect.c) Experimental: dirty mappings are
not compacted immediately, but only after a certain time (for now
10 minutes) since the last change has elapsed.
03-Mar-2003 (Lars Duening) (3.3.409)
- (dumpstat.c) Added the object load time to the OBJ_DUMP data (suggested by
Menaures).
- (dumpstat.c) Removed a memory leak in dumpstat() and dumpstat_dest().
- (closure.c) When converting a lfun closure which is bound to a different
object than it is defined in ('alien lfun closure'), to a string, the
bound object is printed as well as the defining object.
- (ed.c) Consecutive 'z' or 'Z' commands no longer repeat the previous
current line (suggested by Menaures).
02-Mar-2003 (Lars Duening) (3.3.408)
- (configure) It would be useful if I actually updated the configure
script.
02-Mar-2003 (Lars Duening) (3.3.407)
- (ptmalloc.c) Added some documentation and error checks (thanks, Gawain).
- (configure, smalloc) Removed the CHECK_SMALLOC_TOTAL debugging code -
the problem is fixed.
- (configure, smalloc) New diagnostic option MALLOC_SBRK_TRACE to enable
a log of all esbrk() calls and the stats of the allocation requests
causing it. This formalizes the 'DEBUG: MEM ' diagnostics added
in 3.3.399, though the particular string 'DEBUG: MEM ' has been
dropped from the output.
02-Mar-2003 (Lars Duening) (3.3.406)
- (gcollect.c) During the 'clear' phase of the GC, struct member elements
weren't marked as cleared, which prevented proper counting in the
'count' phase and caused the referenced memory blocks being deallocated
prematurely in the 'sweep' phase (reported by Bardioc).
- (mapping.c) Fixed a memory leak in efun m_add().
01-Mar-2003 (Lars Duening) (3.3.405)
- (func_spec, object) New efun variable_exists() and
variable_list().
27-Feb-2003 (Lars Duening) (3.3.404)
- (interpret.c) Improved the error message for when 'mapping[a,b]' is used
with incorrect types at runtime.
27-Feb-2003 (Lars Duening) (3.3.403)
- (gcollect.c, swap.c, mempools) During a the GC a new swap membuffer could
be allocated and then marked 'unreferenced' by the GC, subsequently
causing memory corruption as the swapper continued to use it. The
memory buffers are now held on to during the GC and only freed
afterwards.
24-Feb-2003 (Lars Duening) (3.3.402)
- (strfuns.c) Made the strbuf allocations resilient against out-of-memory
conditions.
- (xalloc) rexalloc() now accepts the MALLOC_TRACE information. The
normal implementation doesn't use it, but they are useful when
instrumenting the allocator code.
24-Feb-2003 (Lars Duening) (3.3.401)
- (interpret.c) With special reference indexing of struct members,
the struct refcount was decremented once too often.
23-Feb-2003 (Lars Duening) (3.3.400)
- (smalloc.c, xalloc.c) Corrected two fatal typos.
23-Feb-2003 (Lars Duening) (3.3.399)
- (smalloc.c, xalloc.c) All esbrk() requests are logged on stdout
as 'DEBUG: MEM ...' messages. This is to find out why certain
muds use so much memory lately.
21-Feb-2003 (Lars Duening) (3.3.398)
- (mempools.c) Corrected a compilation problem.
21-Feb-2003 (Lars Duening) (3.3.397)
- (lex.c) Macro __MSDOS_FS__ is defined on systems using the
MS-DOS filesystem conventions.
20-Feb-2003 (Lars Duening) (3.3.396)
- (mempools, efuns.c) Added the table sizes to the debug_info(DINFO_DATA,
DID_STATUS) result.
20-Feb-2003 (Lars Duening) (3.3.395)
- (mempools, files.c, swap.c, object.c) The file reading efuns (read_file(),
read_bytes(), restore_()) and the swapper now use a persistent buffer
to hold the variable data in memory. Goal is to avoid allocations and
deallocations of large memory blocks which worsen the memory
fragmentation.
18-Feb-2003 (Lars Duening) (3.3.394)
- (smalloc, efuns.c) Since smalloc can split up large small blocks and
handle oversized ones, having the special case of 'unused space' in the
current small chunk is no longer necessary. This also means that the
DID_MEM_UNUSED value from debug_info() no longer exists (b-020506).
16-Feb-2003 (Lars Duening) (3.3.393)
- (smalloc, backend.c, gcollect.c) The smalloc freelist consolidation
is now also called from the backend and does its job whenever
the number of free small blocks is twice the amount the last
consolidation left over.
- (smalloc.c) The maximum small block size has been reduced to 64 Bytes:
it turned out that the larger sizes aren't deallocated often enough
to make the free lists work, which caused unnecessary small chunk
allocations.
- (sprintf.c) Normal (top-level) sprintf() calls now use a static
instance of the fmt_state_t buffer, avoided repeated (de)allocations
of that 130KB structure.
16-Feb-2003 (Lars Duening) (3.3.392)
- (smalloc.c) Since parsing the min-small-malloc already requires
a small chunk allocation, the small chunk allocation using the new
chunk size is also forced to go directly to the system.
15-Feb-2003 (Lars Duening) (3.3.391)
- (ptmalloc) Gawain provided the first locking code for the GC.
- (interpret.c) On 'too deep recursion' errors, also print the depth
and recursion limits. This information is somewhat redundant, but
makes the error logs easier to read.
12-Feb-2003 (Lars Duening) (3.3.390)
- (prolang.y) The illegal switch-case ranges like '100..50' now generate
an error message (reported by Menaures).
08-Feb-2003 (Lars Duening) (3.3.389)
- (ptmalloc) Corrected a compilation problem on x86 gcc (reported
by Nostradamus).
07-Feb-2003 (Lars Duening) (3.3.388)
- (prolang.y) Corrected a fatal error in the 'break'/'continue'
handling.
- (configure) Corrected the check for pthread_atfork().
06-Feb-2003 (Lars Duening) (3.3.387)
- (prolang.y) With the increasing program sizes, using 16-Bit offsets
for the 'break' and 'continue' branches was no longer enough. They
might hold the final offsets, but during compilation they stored
the absolute address of the next 'break'/'continue', which could
exceed 2 Bytes (reported by Alwin).
- (prolang.y) Insertions of 2 byte values are now checked for range.
- (xptmalloc.c, mudlib/sys/debug_info.h) debug_info(DINFO_MEMORY) now
returns the ptmalloc statistics (thanks, Gawain).
- (ptmalloc) GC support is now alpha-functional, but not yet
threadsafe (thanks, Gawain).
- (configure) The check for pthread_atfork() was unreliable.
04-Feb-2003 (Lars Duening) (3.3.386)
- (smalloc.c) Small chunks (except for the first one) are now allocated
from the large blocks. Reason is that during a consolidation, unused
small chunks are returned to the large blocks. Without this change,
new small chunks were always allocated directly from the system
without re-using the space released to the large blocks, so that
over time the process memory usage grew but only a fraction of the
memory was in use (reported by Coogan and Dafire, reproduced by
Menaures).
02-Feb-2003 (Lars Duening) (3.3.385)
- (interpret.c) Assignments to multi-level struct references (a->b->c)
didn't work (reported by Dafire).
30-Jan-2003 (Lars Duening) (3.3.384)
- (simulate.c) Removed a memory leak in the warnf() routine (reported
by Dafire).
29-Jan-2003 (Lars Duening) (3.3.383)
- (structs.c, swap.c) Swapping struct values no longer changes the
refcounts of the referenced type objects. This avoids
a racing condition during the GC, and also prevents a typeobject
from being freed while swapped-out values still require it
(reported by Bardioc).
29-Jan-2003 (Lars Duening) (3.3.382)
- (smalloc.c) In mem_increment_size(), the internal size of the
memoryblock was most cases computed one word too small.
28-Jan-2003 (Lars Duening) (3.3.381)
- (prolang.y, interpret.c) Improved the error message when a given
struct doesn't match the expected struct type.
- (prolang.y) The compiler now checks in struct definitions if a
given base struct is complete. This also
catches 'struct Foo (Foo) { .. }'.
27-Jan-2003 (Lars Duening) (3.3.380)
- (object.c) Restoring a plain lfun-closure no longer worked (reported
by Bardioc).
26-Jan-2003 (Lars Duening) (3.3.379)
- (prolang.y) Corrected a small bug in the code generation for
operators &&= and ||=.
26-Jan-2003 (Lars Duening) (3.3.378)
- (main, lex, prolang, object, simulate.c, configure) Removed the
configuration option INITIALIZATION_BY___INIT and changed the driver
to always use __INIT(). However, the variable sharing between clone
and blueprint is now selectable on a per-program basis with the
pragmas 'share_variables' and 'init_variables'. The default
setting for the pragma can be set with the configuration option
--enable-share-variables and with the commandline arguments
--share-variables and --init-variables.
26-Jan-2003 (Lars Duening) (3.3.377)
- (prolang.y) Removed a compilation problem (reported by Markus).
- (xptmalloc.c) Removed compiler warnings regarding intentionally
unused variables.
26-Jan-2003 (Lars Duening) (3.3.376)
- (configure) The check for pthread_atfork() never succeeded (reported by
Nostradamus).
- (object.c) Removed a compiler warning (reported by Nostradamus).
- (prolang.y) Removed a compilation problem.
25-Jan-2003 (Lars Duening) (3.3.374+.375)
- (prolang.y, interpret.c, func_spec) Implemented short-circuit evaluation
for the operators '&&=' and '||='.
25-Jan-2003 (Lars Duening) (3.3.373)
- (bitstrings.c, mstrings, efuns.c, interpret.c, lex.c) Corrected a string
refcount error in and/or/xor_bits() (reported by Markus).
24-Jan-2003 (Lars Duening) (3.3.372)
- (lex.c) Included #pragma xxx_types settings are no longer restricted
to the include file's scope (reported by Gnomi).
24-Jan-2003 (Lars Duening) (3.3.371)
- (object.c) save/restore didn't look out for shared closures, which
could lead to endless recursions.
- (prolang.y) When compiling the context for inline closures, references
to local variables (for initialisation) were already redirected
into the closure.
23-Jan-2003 (Lars Duening) (3.3.370)
- (configure, ptmalloc.c) Not all systems provide pthread_atfork(),
so configure now checks for it and activates a dummy if
necessary.
23-Jan-2003 (Lars Duening) (3.3.369)
- (structs) Swapping structs during a GC triggered a sanity check
in error (reported by Bardioc).
23-Jan-2003 (Lars Duening) (3.3.368)
- (xalloc.c) I confused two function arguments in the implementation
of rexalloc() *blush*.
22-Jan-2003 (Lars Duening) (3.3.367)
- (prolang.y) The typetracking for assignments to a struct member
was faulty (reported by Markus).
22-Jan-2003 (Lars Duening) (3.3.366)
- (xalloc.c) rexalloc() and malloc_increment_size() didn't update the
xalloc_stat statistics, which could lead to a wrap-around of
that number. Also, rexalloc() is now first trying a
malloc_increment_size().
22-Jan-2003 (Lars Duening) (3.3.365)
- (efuns.c) Efun member() crashed when given a struct as second
argument (reported by Markus).
- (etc/lpc.xml) LPC syntax highlighting for KDE's kate (thanks, Menaures!)
- (prolang.y, interpret.c, closure.c) Implemented struct lookups
on 'mixed' expressions (suggested by Markus).
19-Jan-2003 (Lars Duening) (3.3.364)
- (configure) The '--with-malloc' option didn't quite work (reported
by Nostradamus).
19-Jan-2003 (Lars Duening) (3.3.363)
- (structs.c, gcollect) The GC crashed when encountering self-referential
structs (reported by Nostradamus).
19-Jan-2003 (Lars Duening) (3.3.362)
- (object.c) Changed the error thrown by replace_program() to
a mere warning.
19-Jan-2003 (Lars Duening) (3.3.361)
- (object.c) Restricted replace_program() on the first inherited
program if that program has virtually inherited variables.
See b-030119 for an explanation.
18-Jan-2003 (Lars Duening) (3.3.360)
- (ptmalloc) Gawain provided a bugfix and more work towards GC
support (yes, my previous enthusiasm was premature).
17-Jan-2003 (Lars Duening) (3.3.359)
- (prolang.h) Corrected a compilation problem when using ptmalloc.
17-Jan-2003 (Lars Duening) (3.3.358)
- (ptmalloc) Gawain added GC support to ptmalloc - yay!
- (configure) New with-malloc setting 'default' selects either smalloc
or ptmalloc depending on the support and selection of PThreads.
16-Jan-2003 (Lars Duening) (3.3.357)
- (interpret.c) The 'indexing one past' for strings didn't work
with the empty string (reported by Zonk).
- (prolang.y) When redefining a function, the redefinition can now
have more arguments than the original.
- (lex.c) Escaping newlines in #if conditions on Windows didn't
work (reported by Zonk)
11-Jan-2003 (Lars Duening) (3.3.356)
- (efuns.c) to_string(struct) didn't print the name of the struct,
and leaked memory (reported by Zonk).
- (object.c, prolang.y) Corrected another refcount error in struct
type instances (reported by Zonk).
08-Jan-2003 (Lars Duening) (3.3.355)
- (lex, prolang.y, simul_efun.c) Exported the initialisation of a global
identifier into a single function, to collect all the values in
one place.
07-Jan-2003 (Lars Duening) (3.3.354)
- (several files) Removed the 'no-blueprint' configuration option: there
code is stable.
07-Jan-2003 (Lars Duening) (3.3.353)
- (prolang.y) Corrected another error in non-__INIT initializations
(thanks, Guandalug).
- (prolang.y) Corrected another refcount error in the struct code
(reported by Bardioc).
06-Jan-2003 (Lars Duening) (3.3.352)
- (prolang.y) Removed compiler warnings.
- (prolang.y, simulate.c) Removed compiler errors when not using __INIT
(reported by Guandalug).
- (mudlib/sys/wizlist.h) The wizlist_info() result array was allocated
too small (reported by Dafire).
06-Jan-2003 (Lars Duening) (3.3.351)
- (ptmalloc.c) Using driver.h instead of config.h leads to compilation
errors on some systems (reported by Gawain).
- (smalloc.c, configuration) New configuration option --enable-malloc-check
to enable simple malloc checks like the magic words in smalloc (enabled
by default). The overhead for this is small, but especially in
a development driver this can catch many memory mis-uses.
05-Jan-2003 (Lars Duening) (3.3.350)
- (prolang.y) Corrected another struct related refcount error: function
return types were freed twice (reported by Dafire).
- (structs.c) Changed a call to struct_free() to free_struct() as the
refcount needs to be adjusted properly.
- (swap.c) When freeing an empty swapped-out struct, the refcount needed to
be adjusted before calling struct_free_empty() (reported by Bardioc).
- (make_func.y) When creating type/hookmaps in prolang.y, the linecounting
didn't count the map's continuation lines.
04-Jan-2003 (Lars Duening) (3.3.349)
- (interpret.c) Many mudlibs index strings happily one past the
end, which when used with assignments might lead to
data structure corruption. Since this faulty idiom is in wide
use, I re-allowed it, but now also generate a warning.
- (simulate.c) Generating warnings didn't quite work.
04-Jan-2003 (Lars Duening) (3.3.348)
- (prolang.y) When inheriting functions with struct arguments,
the refcount of the struct type instances wasn't incremented
(reported by Bardioc and Dafire).
03-Jan-2003 (Lars Duening) (3.3.347)
- (smalloc.c) Freeing a small chunk in mem_consolidate() passed the
wrong address to sfree() (reported by Nostradamus and Dafire).
03-Jan-2003 (Lars Duening) (3.3.346)
- (gcollect.c) The struct display code still used SMALLOC_OVERHEAD.
02-Jan-2003 (Lars Duening) (3.3.345)
- (xalloc.c) Freeing unreferenced memory didn't adjust the xalloc_stat
statistic.
02-Jan-2003 (Lars Duening) (3.3.344)
- (many files): Improved and rewrote the struct implementation.
30-Dec-2002 (Lars Duening) (3.3.343)
- (configure, ptmalloc/, xalloc.c) Gawain adapted the threadsafe
ptmalloc2 for use with the driver (GC not supported yet).
- (smalloc.c) Removed the code for the double-linked freelist handling
of large blocks - nobody was using it anymore.
28-Dec-2002 (Lars Duening) (3.3.342)
- (object.c) When saving lfun closures, the function name was looked
up in the wrong program (reported by Dafire).
24-Dec-2002 (Lars Duening) (3.3.341)
- (xalloc.c) Clarified the role of REPLACE_MALLOC (prompted by Gawain).
24-Dec-2002 (Lars Duening) (3.3.340)
- (mregex.c) Efun regreplace() didn't check if for a '\<int>' replacement
pattern the destinated subexpression match existed (reported by Zonk).
20-Dec-2002 (Lars Duening) (3.3.338, .339)
- (lex.c) Added a workaround for an optimizer bug in Cygwin (reported
by Zonk).
20-Dec-2002 (Lars Duening) (3.3.337)
- (actions.c) Throw an error if H_NOTIFY_FAIL hook is missing. This also
prevents the driver from crashing if the H_SEND_NOTIFY hook is
defined (reported by Zonk).
18-Dec-2002 (Lars Duening) (3.3.336)
- (xalloc.c) The max_malloced tracing forgot to count down the allocated
size on xfree()s (reported by Dafire).
18-Dec-2002 (Lars Duening) (3.3.335)
- (object.c) When calling privilege_violation() for restoring efuns,
the current object is passed as 'who' argument (suggested by Gnomi).
17-Dec-2002 (Lars Duening) (3.3.334)
- (lex, object.c) restore_svalue() did not check if a restored efun was
overriden by a nomask simul-efun (reported by Gnomi).
- (comm.c) With pthreads, the driver could crash in remove_interactive()
when the write_cond was destroyed while the thread was still
waiting on it (reported by Lee).
16-Dec-2002 (Lars Duening) (3.3.333)
- (object.c) restore_map_size() stumbled over closure entries (reported by
Jason).
16-Dec-2002 (Lars Duening) (3.3.332)
- (xalloc.c) Corrected a preprocessor conditional (thanks, Gawain!)
16-Dec-2002 (Lars Duening) (3.3.331)
- (xalloc.c) Corrected two small problems (thanks, Guandalug!)
16-Dec-2002 (Lars Duening) (3.3.330)
- (comm.c) If the login object destructed itself in the logon() call,
the driver crashed in the print_prompt() routine (reported by Jason).
15-Dec-2002 (Lars Duening) (3.3.329)
- (object.c) Corrected a compilation error (thanks, Dafire and Jason!).
15-Dec-2002 (Lars Duening) (3.3.328)
- (prolang.y) It is no longer possible to defined a variable to be
of type 'void' (reported by Gnomi).
14-Dec-2002 (Lars Duening) (3.3.327)
- (xalloc, smalloc, sysmalloc, gcollect, dependent files) Cleaned up the
allocator interface somewhat, so that the MALLOC_-tracing is now
handled by the xalloc layer, and that the GC no longer relies on
the internal structures of smalloc.
14-Dec-2002 (Lars Duening) (3.3.326)
- (object.c) Efuns save_() and restore_() can now handle non-lambda
closures, symbols and quoted arrays. This required a new savefile
format, though.
12-Dec-2002 (Lars Duening) (3.3.325)
- (mapping.c) Removed a memory leak: free_empty_mapping() did not
clear the refcount.
11-Dec-2002 (Lars Duening) (3.3.324)
- (doc/concepts/negotiation, src/wk/) Added some telnet protocol
related documentation.
- (func_spec, lex.c, prolang.y, interpret.c) New operators '&&=' and
'||=' (suggested by Croft).
09-Dec-2002 (Lars Duening) (3.3.323)
- (mudlib/telnetneg.c) Updated (thanks, Fiona!)
- (mudlib/test_master.c) Added testcode for using charmode (thanks, Fiona!)
- (comm) Fiona provided more patches: SAVE_NOECHO, which makes sure that
the client can switch to CHARMODE before also setting NOECHO; and
SIMULATE_CHARMODE which allows the mudlib to switch to charmode even
if the client can do only linemode.
- (files.c) Efuns copy_file() and rename() no longer throw errors
on failures, but just return a non-0 value (reported by Menaures).
05-Dec-2002 (Lars Duening) (3.3.322)
- (config.h, comm, gcollect.c, main.c) Replaced USE_PTHREAD by USE_PTHREADS.
- (comm.c) Before printing the prompt, current_object is set to NULL
so that the player's catch_tell() is sure to be able to see the
prompt (reported by mudder@Furtual.ORG).
04-Dec-2002 (Lars Duening) (3.3.321)
- (make_func.y, comm.c, main.c, prolang.y) Removed warnings (reported by
Coogan).
- (comm.c) When logging on a new player, the prompt wasn't printed - in
particular the prompt set by input_to(INPUT_PROMPT) (reported by
Nostradamus).
- (main.c) If the reserved areas can be reallocated, the out_of_memory
flag is reset.
- (simulate.c) catch() reports an 'out_of_memory' condition only
if it was raised during the execution of the guarded code.
- (smalloc.c) Changed OVERHEAD to M_OVERHEAD.
03-Dec-2002 (Lars Duening) (3.3.320)
- (patch-o-matic) Updated to new executable name.
- (prolang.y, object.c) The filenames returned by include_list()
now always start with a '/' to make their reuse in include statements
simpler (suggested by Coogan).
- (mudlib/telnet) Fiona donated the telnet negotiations module from
Wunderland, containing a complete implementation of the telnet protocol
(thanks!).
- (sprintf.c) The %O/%Q formatter stumbled over really large arrays
and mappings: the top-level function ignored if the conversion
routine reallocated the string buffer (reported by Bardioc).
03-Dec-2002 (Lars Duening)
- (sprintf.c, closure.c, pkg-mysql.c) Removed compiler warnings.
03-Dec-2002 (Lars Duening) (3.3.319)
- (Makefile.in) Corrected two typos.
03-Dec-2002 (Lars Duening) (3.3.318)
- (Makefile) Driver executable renamed from 'driver' to 'ldmud'.
- (configure, Makefile) The configure script now tries to figure out
on its own which warning options the compiler supports.
- (comm.c, erq.h) The erq callbacks can now take the returned
data as a string instead of an array (suggested by Dafire).
- (mud/lp-245) Edward S. Marshall found all uses of the new keyword
'function' in the old mudlib and replaced them by something
less offensive to the parser (thanks!).
30-Nov-2002 (Lars Duening) (3.3.317)
- (comm.c) Fiona provided a number of bugfixes for CHARMODE - thanks!
30-Nov-2002 (Lars Duening) (3.3.316)
- (prolang.y) Brainfart: the last patch created a problem, instead of
solving one. The bug was that "*"::fun() looked at _all_ inherited
programs, not just the directly inherited ones.
30-Nov-2002 (Lars Duening) (3.3.315)
- (prolang.y) When making wildcarded supercalls ("*"::fun()), the compiler
takes care that each function is called only once (reported by Gnomi).
29-Nov-2002 (Lars Duening) (3.3.314)
- (sysmalloc.c) This file is no longer needed (actually it has been
useless since 3.2.8-dev.188).
- (dumpstat.c) Didn't compile with MALLOC_sysmalloc.
- (lex.c) pragma_combine_strings was never initialised with a default.
- (lex.c) Changed the FLOAT_MIN/FLOAT_MAX predefined to reflect
the C-float limits, not the C-double limits, as the gamedriver's
floats are somewhere inbetween the two.
27-Nov-2002 (Lars Duening) (3.3.313)
- (patchlevel.h, hosts/be/Makefile, hosts/be/set-version) The version
flags of the BeOS executable are now read from patchlevel.h and not set
directly in the BeOS Makefile.
27-Nov-2002 (Lars Duening) (3.3.312)
- (object.c) Efun transfer() was still incorrect. Funny though that
nobody noticed it before :-) (reported by Nostradamus).
27-Nov-2002 (Lars Duening) (3.3.311)
- (comm.c) The correction of the threads racing condition unfortunately
introduced a deadlock - Gawain found and fixed it (thanks!).
27-Nov-2002 (Lars Duening) (3.3.310)
- (object.c) Corrected the deprecated efun transfer(): the check
for dest->can_put_and_get() was implemented wrong (reported by
Nostradamus).
27-Nov-2002 (Lars Duening) (3.3.309)
- (comm.c) The thread-cleanup function now locks the structure before
performing the cleanup (suggested by Gawain).
26-Nov-2002 (Lars Duening)
- (object.c) restore_object("#0:0") caught the driver in an endless loop
(thanks, Ctx!).
21-Nov-2002 (Lars Duening)
- (etc/patch-o-matic) Contributed by Guandalug - thanks!
21-Nov-2002 (Lars Duening) (3.3.308)
- (closure, interpret.c, gcollect.c, mapping.c, dumpstat.c, efuns.c,
call_out.c, comm.c) Merged lfuns with alien-lfuns - the space advantage
of lfuns over alien-lfuns is no longer that big, and the merger
simplifies the handling.
20-Nov-2002 (Lars Duening) (3.3.307)
- (closure.c) Corrected refcount errors in the handling
of soon-to-be dangling alien-lfun closures.
- (smalloc.c) Made sure that before each call to fatal() the thread-check
is reset.
- (closure, gcollect.c, interpret.c) Moved the context variables back to the
closure_t toplevel - the alien-lfuns needed them as well, and the inner
location was reason for strange crashes.
19-Nov-2002 (Lars Duening) (3.3.306)
- (closure.c, interpret.c) In order to convert a dangling lfun closure
during a replace_program() into a dangling alien-lfun closure, the
closure needs to be created as alien-lfun in the first place (reported
by Pulami).
18-Nov-2002 (Lars Duening)
- (closure, interpret.c, gcollect.c) Moved the context[] array from the top
level of the closure_t into closure_t.function.lfun, where it belongs.
17-Nov-2002 (Lars Duening) (3.3.305)
- (gcollect.c) When cleaning up an untabled string, a string was
freed twice.
- (svalue.h) Corrected the macro arguments to the put_object() family
(reported by Ctx).
- (many files) Removed trailing spaces from lineends.
16-Nov-2002 (Lars Duening) (3.3.304)
- (smalloc.c) If the allocator ran out of memory, the exit handling
triggered the 'Multiple threads' safety check. Not really a problem,
as the driver would exit anyway, but it obscures what is happening.
- (prolang.y) Inline closures spanning include files were flagged
as faulty, still the driver generated code.
16-Nov-2002 (Lars Duening) (3.3.303)
- (gcollect.c) The cleanup code could forget to free a destructed object.
15-Nov-2002 (Lars Duening) (3.3.302)
- (comm.c) The call to remove_flush_entry() could clobber the list
of players to flush if it was called for a player not in the
flush list.
15-Nov-2002 (Lars Duening) (3.3.301)
- (prolang.y) After removing the linenumber information for an inline
closure from the LINENUMBER memory block, the compiler forgot to
adjust the size of the block accordingly (reported by Zonk and
Guandalug).
15-Nov-2002 (Lars Duening) (3.3.300)
- (gcollect.c) He - the new cleanup was permanently disable due to
a typo on the #ifdef expression. Ah, the joys of using the
C preprocessor...
14-Nov-2002 (Lars Duening) (3.3.299)
- (swap.c) Swapping strings during a GC could crash the driver.
13-Nov-2002 (Lars Duening) (3.3.298)
- (sprintf.c) Corrected an off-by-one error which sometimes clobbered
the result of sprintf().
- (efuns.c) get_type_info(,2) on an unbound-lambda crashed the driver
because an uninitialized variable was used (thanks, Ctx!)
- (simulate.c) If the H_NOECHO hook is set, the telnet negotiations
are redirected only after the hook setting is verified (thanks,
Fiona!)
- (comm.c) Corrected a potential problem when an interactive object
with pending data is forcefully made non-interactive: from my
reading of the code it seems that the object remained in the
list of players-to-flush, even though it no longer had a valid
interactive_t attribute.
13-Nov-2002 (Lars Duening) (3.3.297)
- (backend.c) Reset and swapped objects are data-cleaned only
every time_to_clean_up seconds (or 3600 seconds if no cleanup
time is set); active objects are data-cleaned every time
the processing gets to them.
- (swap.c) When swapping strings, the length is now explicitely stored
in the swap file. The old format added a \0 character as terminator,
and consequently malfunctioned or crashed on strings using \0 as
data character.
- (backend.c, sprintf.c) The efuns debug_message(), sprintf() and printf()
can now handle strings with \0 characters better.
- (config.h) Moved the NEW_CLEANUP define into the config.h file and made
it active again; but it still has to be modified by hand if so
desired.
13-Nov-2002 (Lars Duening) (3.3.296)
- (gcollect.c) The cleanup code did not check for the NO_BLUEPRINT
define (reported by Bardioc).
- (gcollect.c, main.c) The new cleanup code seems to interfere with
the swapper, therefore I deactivated it for the moment using
the #define NEW_CLEANUP. If you want the new cleanup code, add
this define in the Makefile to the compiler flags.
12-Nov-2002 (Lars Duening) (3.3.295)
- (port.h) The 'malloc' attribute is now used only with gcc 3 or newer.
- (lex.c) Corrected the line counting with auto-includes (reported by
Coogan).
- (gcollect, backend.c) Added a method to the garbage collector which
cleans up an object, ie. removes all references to destructed
objects from its variables and changes all untabled strings
into tabled ones. This cleanup is performed by the backend as part
of the normal object processing, and by the GC for all objects before
the actual collection begins.
This change solves the problem that destructed objects in the
condensed part of a mapping go unnoticed if the mapping is only
added to/removed from. In Evermore, where objects served as keys
in a particular mapping, this led to an enormous mapping with
stale entries, which the regular GC flagged as 'leaks'.
11-Nov-2002 (Lars Duening) (3.3.294)
- (comm.c) When calling H_NOECHO, the code did not check if the
argument objects were still alive (reported by Fiona).
- (port.h, comm.c, xalloc.h, smalloc.h) Activated GCC attributes for
OS-X compilations, added GCC attribute 'malloc' to the allocator
functions, removed some warnings.
07-Nov-2002 (Lars Duening) (3.3.293)
- (configure.in) The tests regarding which libraries are needed suffered
from a disabling typo (reported by Nostradamus).
- (ed.c) Added a safety checks to uses of P_FNAME - in case it's NULL
(reported by Dafire).
07-Nov-2002 (Lars Duening) (3.3.292)
- (closure.c) If a lfun-closure is left danging by a replace_program(),
it is now converted into an alien-lfun closure pointing to
master::dangling_lfun_closure(). This way the error handler has
a chance to determine the originating object (suggested by Gnomi).
- (closure.c) The handling of dangling alien-lfun closures actually
destroyed the alien.ob entry.
- (interpret, array.c) allocate() used with an array or mapping initialisation
value now creates shallow copies of the initialisation value for each
initialised element (suggested by Oskar).
- (interpret.c) The out-of-bounds condition [<0] was not caught (reported by
Dafire).
- (prolang.y, make_func.y) Removed warnings (reported by Freaky).
04-Nov-2002 (Lars Duening) (3.3.291)
- (smalloc.c) The thread-check in xfree() also triggered when the
memory reserves were released (reported by Bardioc).
03-Nov-2002 (Lars Duening)
- (configure.in) Made the check for -lpthread more robust (reported by
Markus Peter).
01-Nov-2002 (Lars Duening) (3.3.290)
- (comm.c) *blush* Deleted TELOPT_EOR handling by act of stupidity..
31-Oct-2002 (Lars Duening) (3.3.289)
- (comm.c) Added TELOPT_BINARY to the telnet negotiations forwarded
to H_TELNET_NEG (suggested by Fiona).
- (comm.c) Made sure that telnet negotiations are sent out as quasi-
binary messages (before, the default handling of TELOPT_BINARY failed
because that option is character 0; reported by Fiona).
30-Oct-2002 (Lars Duening) (3.3.288)
- (lex.c) When starting a new compile, the order of initialisations
was wrong (in particular: auto-include was handled before the
lexer was set up) (reported by Freaky).
- (configure, (x)erq/Makefile.in) Only link in libraries actually
needed by the erq (suggested by Freaky).
- (configure) Modified the configure so that only required libraries
are added to the compile (suggested by Freaky).
29-Oct-2002 (Lars Duening) (3.3.287)
- (comm, func_spec) find_input_to() and remove_input_to() can now
match on both object and string name.
- (comm.c) Improved the 'already bound' error messages to list
the port number.
- (util/xerq) If the xerq couldn't send all data from a ERQ_SEND request
immediately and thus returned a ERQ_E_INCOMPLETE, it will follow it
up with a ERQ_OK message to the same handle later once all the pending
data has been send (provided by Fiona, thanks!)
- (util/xerq/lpc) Replaced the socketd with the Wunderland daemon
(thanks!).
- (lex.c, prolang, simulate.c) auto-includes are now handled like
normal includes (instead of just placing the text into the textbuffer
and fudging the current_line variable), correcting a source of false
linenumber informations.
- (efuns.c) regmatch( "a", "b*", RE_MATCH_SUBS ) crashed the driver because
the code tried to determine the length of the non-existing first match
(reported by Zonk).
27-Oct-2002 (Lars Duening) (3.3.286)
- (smalloc.c) Added a very primitive safeguard against interleaving
calls to the allocator - I suspect that this is the root cause
for the problems with pthreads.
- (object.c) When resetting an object, the previous_object() was
some random object (reported by Gnomi).
- (comm, func_spec) New efuns find_input_to() and input_to_info()
(suggested by Fiona).
16-Oct-2002 (Lars Duening) (3.3.285)
- (configure) Some systems need libresolv in order to provide
herror() (reported by Coogan).
- (comm.c) Removed a compile warning (thanks, Fiona!).
15-Oct-2002 (Lars Duening)
- (mkfunc.y, Makefile.in, prolang.y) We now assume that on principle
the yacc can't use default actions with anonymous yystack values.
The difference in code is too small to justify all the testing
effort.
- (prolang.y) bison 1.5 helped finding some small flaws.
14-Oct-2002 (Lars Duening)
- (configure) If a requested option (like use-mysql) can't be used
because the system lacks the necessary support, the configure
script issues a warning and exits with return code 1 (suggested
by Freaky).
13-Oct-2002 (Lars Duening) (3.3.284)
- (configure.in) The test for 'long long' was run twice. And if pthreads
are not found, USE_PTHREADS is now deactivated (reported by Freaky).
10-Oct-2002 (Lars Duening) (3.3.282, .283)
- (object.c) Restoring structs in mappings didn't work (reported by Tomba).
- (efuns.c, svalue.h, interpret.c) Evaluation cost of deep_copy() is
now proportional to size and nesting depth of copied arrays
and mappings, if DYNAMIC_COST is defined (suggested by Gnomi).
- (main, configure) Removed the last remnants of debug options CHECK_STRINGS
and KEEP_STRINGS.
09-Oct-2002 (Lars Duening) (3.3.281)
- (actions.c, interpret) The OPC dump function still used char* strings
instead of the new strings (reported by Nostradamus).
- (prolang.y) Removed compilation warnings.
09-Oct-2002 (Lars Duening) (3.3.280)
- (prolang.y) When processing inherited structs, the code overwrote
random memory - especially when there weren't any structs to
process (reported by Bardioc).
- (port.h) No longer includes <values.h> which has been obsoleted
by <limits.h> and <float.h>.
- (config.h, driver.h) Removed the compilation warning when YYDEBUG
was not defined.
08-Oct-2002 (Lars Duening)
- (sprintf.c) Printing a quoted array accidentally used the struct-printing
code (reported by Dafire).
- (interpret.c) structs are not flattened in apply() or with '...'
(suggested by Zonk).
08-Oct-2002 (Lars Duening) (3.3.279)
- (prolang.y) Gah, forgot to remove a debug output.
08-Oct-2002 (Lars Duening) (3.3.278)
- (configure) Forgot to regenerate it.
- (lex.c, prolang) Implemented #'inh::fun lfun closures (b-010801-0).
07-Oct-2002 (Lars Duening) (3.3.277)
- (comm.c, main.c, efuns.c) Removed compilation problems with BeOS.
- (prolang.y) In struct literals, a trailing ',' is now allowed
(suggested by Zonk).
- (prolang.y) Oh My Ghod. The range index [..<expr0>] created faulty
bytecode, maybe even clobbered random memory, if the expression
was anything complicated, like 'm++' or 'm = 4'. This bug
was caused by uninitialized the LPC parser not initializing
the internal return value from parsing <expr0>, so the bug
didn't manifest itself every time (reported by Zonk).
06-Oct-2002 (Lars Duening) (3.3.276)
- (prolang.y, interpret.c, efuns.c, sprintf.c, gcollect.c, exec.h)
structs now carry an identification string internally, which is
displayed in sprintf() and can be retrieved using get_type_info().
06-Oct-2002 (Lars Duening) (3.3.275)
- (prolang.y) New inlines: found a way to implement the old (: expr; :)
form, and corrected an error where the type of context variables
wasn't copied properly, but instead a random value was used.
- (interpret.c) The sanity check for proper stack usage was still
incompatible with the new multibyte efun instructions (reported
by Dafire).
- (prolang.y) Structure IDs are now counted up from 1 instead of 0,
so that efun argument type errors can print id #0 as "just struct"
(reported by Dafire).
- (prolang.y) Straightened out the functions for function generation to
reduce duplicated code.
06-Oct-2002 (Lars Duening) (3.3.274)
- (prolang.y) New inlines: Improved the error handling for the (::) form:
the parser now recovers gracefully if statements are used instead
of expressions (reported by Dafire and Nostradamus).
05-Oct-2002 (Lars Duening) (3.3.273)
- (prolang.y) Inline closures without returntype specification are now
typed to return 'mixed' instead of 'unknown'. This makes them
play better with #pragma strict_types (reported by Dafire).
- (func_spec, interpret.c) Completely forgot to implement the structp()
predicated.
05-Oct-2002 (Lars Duening) (3.3.272)
- (gcollect.c) Oops, MALLOC_TRACE and USE_NEW_INLINES caused a compilation
error.
04-Oct-2002 (Lars Duening) (3.3.271)
- (lex.c, prolang.y) Debugged the new inline closure code - it all seems
to work now. I therefore turned it on by default. (f-020528, f-991104-1)
- (prolang.y) Removed the already inactive code for hybrid struct literals,
as nobody wanted them.
- (autoconf/configure.in) Corrected the problem with newer autoconfs.
03-Oct-2002 (Lars Duening) (3.3.270)
- (prolang.y) The new inline closures is alpha-complete: I think I have
implemented everything, but I haven't tested it yet.
- (lex.c, prolang.y) Some internal changes to make implementation of
new inline closures simpler.
02-Oct-2002 (Lars Duening) (3.3.269)
- (prolang.y) Added the basic infrastructure to compile an inline closure.
Still missing: context recognition, translation of local variable
uses, extended context (': ..' syntax), mandatory local scopes,
and line numbers.
01-Oct-2002 (Lars Duening) (3.3.268)
- (comm.c) Forgot a parameter in an error message (thanks, Freaky!)
- (main.c, comm) The hostname was initialized to late, so the debug.log
file was opened with the wrong name (reported by Dafire).
30-Sep-2002 (Lars Duening) (3.3.267)
- (comm.c) Changed the fprintf() in the thread cleanup routine into a
malloc-friendlier dprintf1().
- (main.c) Added a check into debug_message() if the name of the
debug log file has already been set (reported by Dafire).
- (simulate.c) The driver now checks if an object to be loaded appears
out of nowhere while it is being compiled (this can happen if the mudlib
warning handler is careless with rename_object()) and throws an error
(reported by Gnomi).
- (main.c, comm) New commandline options --hostname and --hostaddr
to override the values returned by the system. In particular,
--hostaddr will be used as the address to open to the driver
ports.
27-Sep-2002 (Lars Duening) (3.3.266)
- (comm, main.c, configure) Based on a patch by Gawain, PTHREADS and
PCRE (requires Fiona's patch) can now be configured like other
options. New commandline option --max-thread-pending to set
the limit for pending data to write.
26-Sep-2002 (Lars Duening)
- (interpret.c) struct can now be compared for equality and
inequality; they can be used as values in foreach() statements
and with the '...' operator resp. apply().
25-Sep-2002 (Lars Duening)
- (comm.c) If a connection is marked for removal (.do_close != 0),
telnet commands can still be sent. This is to allow the input_to()
handling to properly reset the connection to linemode even if
the input_to() handler has called remove_interactive().
- (backend, smalloc.c) Made the GC request log output nicer.
25-Sep-2002 (Lars Duening) (3.3.265)
- (comm, gcollect.c) Removed compiler warnings, and a crash
in pthreads thread cleanup (reported by Dafire)
25-Sep-2002 (Lars Duening) (3.3.264)
- (interpret.c) The LPC tracing code crashed when used with lambda
closures or with call_resolved() (reported by Nostradamus).
24-Sep-2002 (Lars Duening) (3.3.263)
- (comm, backend.c, gcollect.c) smalloc is not threadsafe, which
caused the implementation of USE_PTHREAD code to trash the
memory structures. To solve the problem, all memory allocations
and deallocations are done by the main thread.
- (gcollect.c) Program strings were counted twice, causing
a creeping memory leak.
Patches from Guandalug:
- (efuns.c) Efun deep_copy() couldn't be used with structs.
- (object.c) Efun function_exists(): corrected an error message.
- (closure.c) Converting a sefun-closure to a string looked up the
name in the efun table instead of the sefun table.
23-Sep-2002 (Lars Duening)
- (prolang.y) Using a range foreach() with an empty loop body crashed
the driver (reported by Nuutti).
- (comm.c) USE_PTHREAD: Restructured the writer_thread() code a bit.
19-Sep-2002 (Lars Duening) (3.3.262)
- (etc/lpc-mode.el) LPC mode for EMACS, by Vivek Dasmohapatra.
- (func_spec) The spec for set_modify_command() excluded that the
efun could take '0' as argment (reported by Kent!)
- (object.c) Efun inherit_list(): the tagging of virtual inherits
didn't work (reported by Dafire).
- (prolang.y) The test for duplicate toplevel inherits got confused
when virtual inherits occured (reported by Zonk via Dafire).
18-Sep-2002 (Lars Duening) (3.3.261)
- (func_spec, interpret, simulate) Added the infrastructure to create
context closures, and to access the context variables. Now we
'just' need the support in the compiler.
18-Sep-2002 (Lars Duening) (3.3.260)
- (gcollect.c) Oops, didn't compile with MALLOC_TRACE enabled.
18-Sep-2002 (Lars Duening) (3.3.259)
- (doc/obsolete/) New directory to hold obsolete manpages - useful
when reworking old code (suggested by Coogan).
- (func_spec, object, string_spec) Efun transfer() is now officially
deprecated.
- (doc/hook/) New directory to document the driver hooks
one-per-file.
- (func_spec, parse, other files) Removed the compat-mode version
of parse_command(); the efun itself is now configured over
the config option use-parse-command.
- (func_spec, configure, other files) Efuns set_is_wizard(),
set_light(), and process_string() can now be configured.
- (closure, efuns.c, sprintf.c) Streamlined the conversion of closures
to strings.
- (bytecode.h) New include to reduce dependencies on exec.h .
- (func_spec, actions) New efun match_command().
17-Sep-2002 (Lars Duening) (3.3.258)
- (bitstrings.c, swap.c, simulate.h) Removed warnings (reported by Dafire).
- (comm.c) ECONNREFUSED is recognized as error (suggested by Coogan).
- (prolang.y) Assignments to a struct member caused the LPC compiler to
dereference uninitialized memory when the member lookup failed
(reported by Bardioc).
16-Sep-2002 (Lars Duening) (3.3.257)
- (comm.c) With PThreads: forgot to detach new threads after creation
(thanks, Gawain!)
- (configure) The object statistic seems to be correct now, so the
OSTAT diagnostics are disabled by default.
- (closure.c) The argument checking when compiling sefuns in a lambda
closure didn't work properly (reported by Coogan).
- (exec.h) The mask SEC_TYPE_INFO was defined improperly.
- (prolang.y) If an explicite call to an inherited function couldn't
be compiled, the argument type stack got popped too often - eventually
causing memory corruption.
15-Sep-2002 (Lars Duening) (3.3.256)
- (bitstrings.c, closure, efuns.c, interpret, gcollect.c, object.c,
simul_efun.c, swap.c)
Reduced coupling to instrs.h .
- (closure, ed.c, lex, parse.c, parse_old.c) Reduced coupling to lang.h .
- (func_spec, lex.c, object) Config option COMPAT_MODE now just defines
the default run mode.
15-Sep-2002 (Lars Duening) (3.3.255)
- (mstrings.c) Corrected the search statistics.
- (prolang.y, lex, interpret.c, simulate, func_spec) New pragma
'warn_deprecated' causes the compiler to print warnings when
a deprecated efun is used (suggested by Dafire).
- (regexp, mregex.c) Removed name clashes with system libraries.
15-Sep-2002 (Lars Duening) (3.3.254)
- (mapping.c) Accidentally broke the mapping functionality with the
new svalue_cmp()/svalue_eq() functions.
- (prolang.y) If a wildcarded super call couldn't be resolved, a
spurious arg-frame was left on the stack (reported by Dafire).
- (prolang.y) The LPC compiler didn't check addition was attempted
on known structs. Vice versa, the type checking on assignment
was too strict (reported by Bardioc).
13-Sep-2002 (Lars Duening) (3.3.253)
- (interpret.c, prolang.y) Removed compiler warnings.
- (array, mapping.c, pkg-alists.c, i-svalue_cmp.h) Exported the
svalue comparison inline functions into their own include file.
- (closure, gcollect.c, other files) With USE_NEW_INLINES: lfun closures
can now carry a bunch of context values with them.
12-Sep-2002 (Lars Duening) (3.3.252)
- (interpret.c) DYNAMIC_COSTS now also covers array additions.
- (prolang.y) When inheriting variables, the function to
adjust the struct-id inadvertendly stripped away the
inheritance flags. This caused virtual variables to
go uninitialized or worse.
11-Sep-2002 (Lars Duening)
- (prolang.y) Oops, typos in the constant-struct code when __INIT
is not used (thanks, Guandalug).
11-Sep-2002 (Lars Duening) (3.3.251)
- (main.c) Redesigned the argument definition array to combine all
information (short version, long version, short and long help
text) in one place. Also got rid of the COMPAT arguments.
10-Sep-2002 (Lars Duening) (3.3.250)
- (func_spec, efuns) The efuns to_array() and to_string() can now
handle structs; new efun to_struct().
- (prolang.y) Removed the ability to create struct literals
with named and unnamed initializers - it's borderline
featuritis.
09-Sep-2002 (Lars Duening) (3.3.249)
- (exec.h) The NAME_HIDDEN flag interfered with the struct id in
full variable types.
- (config.h.in) Oops, USE_STRUCTS was controlled by the PCRE
configuration option.
- (configure, config.h.in, prolang.y, lex.c) Just for fun I added
the necessary rules for a new inline function syntax. This
change is controlled by configuration option use-new-inlines,
and since it is incompatible with existing code, it is by
default OFF.
08-Sep-2002 (Lars Duening) (3.3.248)
- (dumpstat.c) The status dump (also accessed by debug_info(2))
couldn't handle structs (thanks, Markus).
- (efuns.c) The argument checks for debug_info(DINFO_STATUS)
accepted objects instead strings (thanks, Markus).
- (prolang.y) Assignments of mixed/mixed* to struct don't need
a cast (suggested by Markus).
06-Sep-2002 (Lars Duening) (3.3.247)
- (object.c) Restoring arrays or structs confused the two types
(thanks, Markus!).
06-Sep-2002 (Lars Duening) (3.3.246)
- (prolang.y, func_spec, interpret.c, closure.c, object.c, swap.c,
efuns.c) structs are now fully implemented (at least as far as I
can see); internally they are used and accessed like arrays
(f-981229-05).
05-Sep-2002 (Lars Duening) (3.3.245)
- (prolang.y) The function header for __INIT() was generated incorrectly
(reported by Markus).
- (exec.h, prolang.y, svalue.h, gcollect.c, interpret.c) Implemented
constant struct initializations (!INITIALIZATION_BY___INIT).
04-Sep-2002 (Lars Duening) (3.3.244)
- (gcollect.c, prolang.y, exec.h, object) Implemented the parsing
and inheritance of struct definitions (the latter untested).
- (mstrings.c) The string statistics seem to be correct, so I removed
the 'SSTAT' diagnostics altogether.
04-Sep-2002 (Lars Duening) (3.3.243)
- (exec.h, prolang.y, make_func.y, closure.c, main.c) Added a compile-time
type 'TYPE_STRUCT' and provided space in the function header to
store it. A side effect is that ALIGN_FUNCTIONS is now mandatory; it
was the default anyway and nobody I know ever disabled it. Another
side effect is that I found another magic constant which I hadn't
given a macro name before.
04-Sep-2002 (Lars Duening) (3.3.242)
- (mstrings.c) I found one place where the string statistics were
computed wrongly.
03-Sep-2002 (Lars Duening)
- (interpret, lex.c, comm.c) Lambda-callbacks now clear the evaluation
costs before processing an error as well.
- (swap.c) The object statistics get messed up when the GC swaps objects.
Let's see if this change corrects all of the discrepancies. In
general the reason for the discrepancies was that variables
were counted more often as 'swapped in' than they had been
swapped out.
02-Sep-2002 (Lars Duening) (3.3.241)
- (mstrings.c) The SSTAT diagnostic produced far too much output; but
since the test run in OSB gave me a first clue, I can now search
with less brute force.
02-Sep-2002 (Lars Duening) (3.3.240)
- (prolang.y) Added a missing %endif (thanks, Guandalug!)
01-Sep-2002 (Lars Duening) (3.3.239)
- (mstrings.c) The string statistics are off - added 'DEBUG: SSTAT'
diagnostics when that happens.
30-Aug-2002 (Lars Duening) (3.3.238)
- (efuns.c, lex.c, make_func.y) Support for international characters
was broken (thanks, Oskar!).
29-Aug-2002 (Lars Duening) (3.3.237)
- (prolang.y, lex.c, main.c, configure) Added syntax support for structs
- no code yet to actually use them.
28-Aug-2002 (Lars Duening) (3.3.236)
- (prolang.y) When removing the arg-frame instruction from a call_other,
the compiler looked up the wrong program offset.
28-Aug-2002 (Lars Duening) (3.3.235)
- (mud/lp-245) Provided all object lfuns with proper argument and return
types.
27-Aug-2002 (Lars Duening) (3.3.234)
- (prolang.y) Fixed two typos in messages.
26-Aug-2002 (Lars Duening)
- (swap.c) The OSTAT diagnostic for swap-in subtracted instead of added
to compute the expected new tot_alloc_object_size value (reported
by Coogan).
25-Aug-2002 (Lars Duening)
- (comm.c) The pthreads code didn't compile (reported by Markus).
24-Aug-2002 (Lars Duening) (3.3.233)
- (efuns.c) Efun terminal_colour(): some random characters were appended
to the result string (reported by Markus).
- (object.c) If restoring from a file fails, the error message lists
the line number concerned.
23-Aug-2002 (Lars Duening) (3.3.232)
- (efuns.c) Efun terminal_colour(): the bugfix to handle single '%'
was incomplete (reported by Markus).
21-Aug-2002 (Lars Duening) (3.3.231)
- (comm.c, object.c, simulate.c, swap.c) Corrected some warnings
(reported by Dafire).
- (interpret, and some more files) Master applies caused by external events
(like ERQ messages) are now distinguished from internal calls
(like valid_write()) so that the error handling for external calls
receive the full eval cost benefits (suggested by Fiona).
- (Makefile.in s): Added missing @EXEEXT@ tags.
20-Aug-2002 (Lars Duening) (3.3.230)
- (main.c) Needed to #include <netdb.h> on Solaris to get the
MAXHOSTNAMELEN macro (thanks, Coogan).
- (util/erq/erq.c, util/xerq/erq.c) Forgot the timestamp in the
initial startup message.
- (port, files.c, comm.c, hosts/unix.h) Cygwin corrections.
- (config.h, configure, driver.h, erqs) New configuration option
with-erq-debug sets the new config.h macro ERQ_DEBUG which
defines the ERQ debug level. No more '-DDEBUG' to enable
the debugging code in the ERQs (suggested by Bill).
19-Aug-2002 (Lars Duening) (3.3.229)
- (lex.c) An error in a permanent define given on the command line
would crash the driver because the lexer called error() before
the VM had been set up.
- (main.c) If the driver uses the default debug.log file, its (mudlib)
name is available in the predefined macro __DEBUG_LOG__ (suggested
by Mandragon).
- (driver.h, config.h) Made the config.h macro DEBUG invisible to the
ERQs as their debugging mode is controlled by their Makefiles.
- (util/erq/erq.c, util/xerq/erq.c) The ERQs now print their name
and compilation date to stderr on startup.
- (closure.c) Efun symbol_efun() freed symbol-svalues as strings
(reported by Dafire).
- (regexp.c) regexec() returned a RE_MATCH for a failed match,
causing all kinds of neat failures (thanks, Guandalug!)
18-Aug-2002 (Lars Duening) (3.3.228)
- (lex.c) Added predefined macros __RESET_TIME__ and __CLEANUP_TIME__
(suggested by Elric).
18-Aug-2002 (Lars Duening) (3.3.227)
- (interpret.c) vefun argument error messages printed the wrong
instruction name since they still expected a 'num_args'
bytecode (reported by Markus).
- (efuns.c) Efun terminal_colour(): when checking for the existance
of a '%^' marker in the text, a single '%' caused the code
to search random memory (reported by Markus) (b-020228-1).
17-Aug-2002 (Lars Duening) (3.3.226)
- (array.c) In the array-array operations, the optimized handling
for handling short arrays didn't clean out destructed
object references (reported by Markus).
16-Aug-2002 (Lars Duening) (3.3.225)
- (array.c) In the array-array operations, the algorithm didn't
handle multiple occurances of the same value well (reported
by Markus).
15-Aug-2002 (Lars Duening) (3.3.224)
- (array.c) In the array-array operations, a comparison was made
using unallocated memory (reported by Markus).
14-Aug-2002 (Lars Duening) (3.3.223)
- (configure) Optimization option -funroll-all-loops seems to
create buggy code, so I removed it from the configure.
- (object.c) Efun tell_room() leaked memory.
- (simulate.c) check_valid_path() leaked the pathname when
an error occured.
14-Aug-2002 (Lars Duening) (3.3.222)
- (comm.c) Compilation broke under BeOS.
- (object.c, swap.c, simulate.c) Removed warnings.
- (object.c) An error message printed memory garbage.
- (array) Forgot to export array_cmp() and shrink_array() when
using alists (reported by Markus).
14-Aug-2002 (Lars Duening) (3.3.221)
- (array, interpret.c, prolang.y) Added the symmetric difference
operators '^' and '^=' for arrays; complemented '|' for arrays
with '|='.
- (array.c) Modified the sorting routine get_array_order() so that
for small arrays linear-exchange is used instead of heapsort.
This trades less overhead for worse complexity.
13-Aug-2002 (Lars Duening) (3.3.220)
- (configure) The VERBOSE_OPCPROF define in config.h got clobbered.
- (interpret.c) I removed the copy-on-write for mappings again -
it broke more than it fixed.
13-Aug-2002 (Lars Duening) (3.3.219)
- (regexp, mregex) Changed the original RE package to return
error codes instead of calling regerror(). This puts it more
in line with the PCRE implementation.
- (configure, setting files) PCRE is now compilation default; however
I disabled it explicitedly in the setting files.
- (regexp, pcre) Whenever the RE engine has to backtrack, the eval
cost is incremented and checked. This will catch pathological
matches like regexp(({"=XX==================="}), "X(.+)+X")
(regexp mod provided by Fiona).
This completes the addition of PCRE to LDMud (f-010406-0).
12-Aug-2002 (Lars Duening) (3.3.218)
- (lex.c) New predefined macros __CATCH_EVAL_COST__ and
__MASTER_EVAL_COST__ to carry the corresponding
configuration options over to LPC (suggested by Menaures).
- (Makefiles, configure, config.h) Moved the debugging options into
config.h to ensure clean recompilations, and made them
configurable through the normal configure mechanism.
- (make_func.y, lotsa files) Efuns with more than four fixed
arguments are implemented as vararg efuns. In addition,
because the vararg efun functions have a different signature
than the fixed efun functions, the former now use 'v_xxx()'
as standard name.
11-Aug-2002 (Lars Duening)
- (driver.h, object.c, simulate.c, swap.c) Defining debug macro
CHECK_OBJECT_STAT allows tracing of all changes to the
tot_alloc_object(_size) statistics. Aim is to find the
discrepancy in the 'status' command. To activate the
tracing, the commandline option '--check-object-stat' must
be given.
- (interpret.c) The operations <map> += <map> and <map> -= <map>
now implement the copy-on-write semantic to mirror the
behaviour of the related array operations (suggested by Dafire).
- (interpret.c) get_type_info(<closure>,2) did not return the
bound object for efun, simul-efun and operator closures
(reported by Gnomi).
- (interpret.c) Attempting to replace a program in an object
which already has closures bound no longer raises an error,
but issues a debug_message() (suggested by Pulami).
- (make_func.y) Removed two warnings by bison (reported by Gawain).
10-Aug-2002 (Lars Duening) (3.3.217)
- (closure.c) In efun symbol_function(), symbols were freed as
strings (reported by Freaky).
- (main, backend.c) Signal USR2 forces the driver to reopen the
host.debug.log file (thanks, Gawain!).
- (comm, gcollect.c) Experimental: Defining USE_PTHREAD (if your
system has pthread support) activates code which uses threads
to write the socket data to the network in the background.
Intention is to avoid EWOULDBLOCK errors on slow connections
(thanks, Gawain!)
08-Aug-2002 (Lars Duening)
- (comm.c) When using IPv6, get_host_ip_number() used a too small
buffer (thanks, Fiona!)
- (backend.c) Improved the 'doing a GC' messages somewhat.
05-Aug-2002 (Lars Duening) (3.3.216)
- (mapping.c) Embarassing: the bugfix broke map() and filter()
for all non-multi-value mappings (reported by Casey).
05-Aug-2002 (Lars Duening) (3.3.215)
- (prolang.y) Inheriting the same program twice at the top level
now raises a warning, resp. an error in pedantic mode.
- (simulate.c) If a closure is called from limited() and self-destructs,
the driver would try to free the now-invalid closure argument
and crash (this happened a lot in EotL) (thanks, Casey!).
- (interpret.c) In DEBUG mode, the functions free_object_svalue() and
free_string_svalue() check that they really get the proper data type.
- (efuns.c) Efuns filter() and map(): when used with multi-value
mappings, the driver checks if the called function kept a reference
to the passed array with the values. If yes, a new array is
created for the next iteration to avoid overwriting the old
one (reported by Fiona).
- (interpret.c) When collecting the traceback in a catch(), the
file and line information was used, but not initialized, occasionally
crashing the driver. In addition, in a couple of cases when the
file and line information can't be determined, the file was
left undefined (thanks, Gnomi!)
16-Jul-2002 (Lars Duening) (3.3.214)
- (efuns.c) regmatch() returns 0 instead of the empty string for
non-matches (suggested by Fiona).
- (efuns.c) regmatch() takes and returns a start index for repeated
matches over the same string (suggested by Fiona).
15-Jul-2002 (Lars Duening) (3.3.213)
- (mud/lp-245) The wizlist() simul-efun didn't print proper failure
notices (reported by Vandergnome).
- (gcollect.c) In a GC the list of destructed objects was handled
last, by which time the list might already have been clobbered.
Moving the handling first should plug a memory leak (reported by
Dafire).
- (prolang.y) If a variable was inherited multiple times, the driver
generated a senseless warning (reported by Zora).
- (efuns.c, main.c) Added some support for locales; in
particular the driver now uses the locale defined in the LANG
environment variable for character conversions (thanks, Oskar!).
- (simulate.c) Efun callbacks misparsed the arguments when only the
function name and extra arguments, but no object was provided.
- (efuns.c) Corrected a bug in regreplace() was caused by matches
on null-string patterns (reported by Dafire, fixed by Fiona -
thanks!).
14-Jul-2002 (Lars Duening) (3.3.212)
- (etc/memusage) Fiona updated the script to make it more robust and
work with the new OBJ_DUMP format. Furthermore the constants
for $DOMAINS and so on do work now.
- (files.c) When GETDIR_PATH was used with get_dir(), the resulting
strings had trailing NUL characters (thanks, Guandalug!)
- (mstrings.c) Under some circumstances, strstr() returned positions
after the end of the string. Found by Acius and fixed by Guandalug
(thanks!).
05-Jun-2002 (Lars Duening) (3.3.211)
- (prolang.y) Oops, yesterday's bugfix was not quite corrected.
04-Jun-2002 (Lars Duening) (3.3.210)
- (prolang.y) If a method in a virtual inherit is rendered invisible,
but also made available again through a parallel inherit of the same
program, the compiler resolved the visible function to the
wrong inheritance, causing the driver to crash (b-020530).
17-May-2002 (Lars Duening)
- (backend.c) The new arguments to garbage_collection() are ignored
when the memory allocator doesn support a GC.
13-May-2002 (Lars Duening) (3.3.209)
- (hash.c) The hash functions were still incorrect for 0-length
strings, causing FinalFrontier to crash on boot (reported
by Dafire).
- (config.h.in, Makefile.in, autoconf/configure.in) TRACE_CODE
is now configurable through the configure script, and thus
is located in config.h and no longer in Makefile.
- (gcollect, interpret.c, func_spec) Optional filename argument
to efun garbage_collection() can specify a new GC log file
for the next GC. The filename is validated through
master::valid_write() (f-020312).
07-May-2002 (Lars Duening) (3.3.208)
- (mapping.c) 'mapping += mapping' now throws an error when the
mappings are of differing width (reported by Alfe and Coogan).
- (prolang.y) New notation '([:<expr>])' as shortcut for
m_allocate(0, <expr>) (suggested by Alfe).
06-May-2002 (Lars Duening) (3.3.207)
- (smalloc.c) With CHECK_OBJECT_GC_REF, small chunks could lead to
misleading diagnostics during the GC.
03-May-2002 (Lars Duening) (3.3.206)
- (interpret) The H_DEFAULT_METHOD can now be specified with varargs
arguments and still receive by-reference variables, similar to
the call_other() sefun (reported by Bardioc).
- (prolang.y) Reworked the program block reallocations to make sure
that their bounds won't be overwritten. This could have been
the reasons for the crashers on corrupted memory (reported by Coogan).
01-May-2002 (Lars Duening)
- (settings/dt2) Updated the DeeperTrouble settings file; and also
removed the mud/dt2 directory since it's no longer necessary
(thanks, Lasse!).
26-Apr-2002 (Lars Duening) (3.3.205)
- (prolang.y) Hiding an inherited private nosave variable with an
inherited non-private variable didn't work (reported by Gnomi).
- (prolang.y, lex.c, simulate.c) Compiler error and warning messages
all have the format '<file> line <line>: <text>' now.
- (prolang.y, swap.c) Oops, the linenumber structure was allocated too
small on creation, and read in incorrectly from swap.
- (driver.h) Deactivated the debug defines CHECK_MAPPING_TOTAL
and CHECK_OBJECT_REF since these bugs seem to be fixed.
25-Apr-2002 (Lars Duening) (3.3.204)
- (comm.c) Using unbound lambdas for prompts crashed the driver
(reported by Gnomi).
- (driver.h, gcollect, smalloc) When macro CHECK_OBJECT_GC_REF is
activated, every supposedly non-object memory reference in a GC is
checked if it points to an object. If yes, a diagnostic is printed
to gcollect out. Requires MALLOC_TRACE to work.
21-Apr-2002 (Lars Duening) (3.3.203)
- (exec.h, prolang.y, interpret.c, object.c, swap.c) Linenumbers are
now kept in a separate memory block, which makes swapping them
out and back in simpler.
20-Apr-2002 (Lars Duening) (3.3.202)
- (prolang.y, lex.c) Calls to the master during a compilation now check
the available evaluation costs. If the limit is exceeded, a
compilation error is generated.
- (swap.c) Removing a program block from the swap no longer crashes
if the program doesn't have line numbers (reported by Pixie).
- (prolang.y) Calls to undefined functions now generate a warning
when detected in functions without typechecking if #pragma
pedantic is in effect (before the compiler silently inserted
a prototype).
19-Apr-2002 (Lars Duening)
- (prolang.y) Removed a few bison warnings (reported by Menaures).
18-Apr-2002 (Lars Duening) (3.3.201)
- (prolang.y) When passing a wrong argument to a varargs function, the
error message gave the wrong argument number (reported by Gnomi).
- (func_spec, mapping) New efun m_add().
09-Apr-2002 (Lars Duening) (3.3.200)
- (prolang.y) The improved type checking on <op>= accidentally
broke the type checking on the plain assignment (reported by Dafire).
- (mregex.c) Substituting patterns copied garbage characters, too
(reported by Markus).
- (hash.c) Made the hash functions resistant against 0-length
strings.
08-Apr-2002 (Lars Duening) (3.3.199)
- (efuns.c) The length computation for the result of regreplace()
was wrong when using closure-substitutions (reported by Markus Peter
and Dafire).
- (prolang.y) Improved the type checking on the <op>= operators
to match what the VM actually implements (reported by Menaures).
05-Apr-2002 (Lars Duening) (3.3.198)
- (efuns, rxcache, ed.c) Implemented regexp substitution and
made ed and regreplace() work with PCRE.
- (efuns, rxcache, func_spec) New efun regmatch().
- (main.c, rxcache.c) PCRE-related bugfixes.
- (pkg-pcre.c, pcre/internal.h) New unified wrapper for all PCRE
modules. For this to work, the PCRE internal.h had to be
protected against multiple inclusion.
- (mregex) The files formerly known as rxcache.[ch].
04-Apr-2002 (Lars Duening) (3.3.197)
- (mapping.c) During a GC, the .hash member in a mapping does not
point to a mapping-hash structure - the statistics code
ignored that (b-011015-0).
- (gcollect, swap.c) Made the GC status variable less reliant
on magic numbers.
- (swap, gcollect.c, object.c, simulate.c) When removing the swap
entry for a modified program, the code now also makes sure
that the linenumbers are loaded back into memory.
03-Apr-2002 (Lars Duening) (3.3.196)
- (efuns.c, rxcache.c) The old regexp code is usable again.
- (prolang.y) '<string> *= <int>' didn't compile (reported by Dafire and
Menaures).
- (swap, gcollect.c, object.c, simulate.c) A hunch: when a program is
swapped for the first time, the driver writes the struct as it
is to the disk. On later swap-ins, this data is read directly
into memory, but never written again. If in the meantime
the prog->blueprint pointer changed, this change will be lost
after the next swap in. It would require a rare sequence of
activities to make this a problem, but it's possible. The change
is therefore to remove the swap block whenever prog->blueprint
changes; let's see if this helps (b-020228-0).
02-Apr-2002 (Lars Duening) (3.3.195)
- (efuns.c) Efun regexplode() did not remove all its arguments
(maybe b-020331).
- (efuns.c) Efun regexplode() misinterpreted how to extract
substrings from a string.
- (interpret.c) When calling the default method, the code to
massage the stack in fact clobbered memory (b-020324, b-020328-0).
31-Mar-2002 (Lars Duening) (3.3.194)
- (simulate.c) Load errors during the initial master load crashed
the driver in the error handling.
31-Mar-2002 (Lars Duening) (3.3.193)
- (rxcache, efuns.c, ed.c, mstrings.c) The driver again compiles
when PCRE is activated, but substituting strings is not
implemented yet; and matching strings hasn't been tested.
30-Mar-2002 (Lars Duening) (3.3.192)
- (driver.h) The blueprint code helped some people (but not all), so I
re-activated it as a counter-check.
- (bugs/) Updated the files.
28-Mar-2002 (Lars Duening) (3.3.191)
- (efuns.c) Passing 0 as second argument to md5_crypt() caused
to the driver to write over array bounds (reported by Markus Peter).
- (interpret.c) The fatal() message in free_svalue() printed
the wrong value.
28-Mar-2002 (Lars Duening) (3.3.190)
- (rxcache, efuns.c, ed.c, func_spec, mudlib/sys/regexp.h)
Streamlined the regexp compilation options and made them
accessible from LPC. The actual RE matching is still not
supported for PCRE.
27-Mar-2002 (Lars Duening) (3.3.189)
- (rxcache) Added the basic code to compile and free PCREs. The
matching is still not supported, so at the moment the driver
won't even compile with PCRE activated :-)
27-Mar-2002 (Lars Duening) (3.3.188)
- (wiz_list.c) Don't call master::get_wiz_name() when there is no
master. Otherwise a simple warning during the initial master
load would abort the driver (reported by Frank Syse).
- (driver.h, lots of files) If debug macro NO_BLUEPRINT is defined,
the driver no longer tracks the blueprint for a program structure.
This somewhat disables the blueprint() efun, but if it solves
the object refcount problem, I know at least where to look.
- (func_spec, actions.c) Efun query_verb() now takes an optional
flag to return the verb as specified in the add_action() instead
of the verb given by the user (suggested by Dafire).
26-Mar-2002 (Lars Duening) (3.3.187)
- (array.c, mapping.c) Made sure that the callback structures are
properly released on errors.
25-Mar-2002 (Lars Duening)
- (lex.c) *sigh* 'ifstate_t' is also a system type (reported by Alwin).
- (comm.c) Removing the last pending input_to() did not reset the
'input_to pending' flag in the interactive structure (reported
by Gnomi).
21-Mar-2002 (Lars Duening) (3.3.186)
- (lex.c) The lexer's 'struct ifstate' clashes with an 'enum ifstate'
defined on some systems for the networking stack (reported by Alwin).
- (interpret.c) Removed the negative indexing on control_stack
and value stack by introducing dummy entries at the bottom of
each.
19-Mar-2002 (Lars Duening) (3.3.185)
- (interpret.c) CHECK_OBJECT_REF: The destructed objects are now
checked on F_RETURNs and after all efuns, in order to use
fewer cycles.
16-Mar-2002 (Lars Duening) (3.3.184)
- (array.c) And this should be the last piece of code which made
assumptions about free_svalue().
- (func_spec, efuns) New efun blueprint().
12-Mar-2002 (Lars Duening)
- (Makefiles) Changed default optimization level from High (-O4)
to Medium (-O2), since compilers get notoriously unreliable
at high optimization.
11-Mar-2002 (Lars Duening) (3.3.183)
- (simulate.c) The CHECK_OBJECT_REF check was still overzealous;
unfortunately not with the FF mudlib I tested it with. Hmpf.
- (xalloc.c) The heap/stack gap check didn't expect the stack to
be located under the heap, as Cygwin does it.
10-Mar-2002 (Lars Duening) (3.3.182)
- (actions.c, simulate.c) The CHECK_OBJECT_REF check was overzealous
and didn't track properly the changes in object sentences. Sorry.
- (func_spec, object.c) Efun all_environment() did not accept destructed
objects as argument as documented (reported by Pulami and Gnomi).
09-Mar-2002 (Lars Duening) (3.3.181)
- (xalloc) The implementation of the heap/stack check didn't work
on architectures with really big address spaces - corrected that.
- (mapping.c, interpret.c, object.c, efuns.c) When adding new values
to mapping, the code didn't check if the memory could be allocated
(reported by Menaures).
- (doc/efun) More german translations from Pulami.
07-Mar-2002 (Lars Duening) (3.3.180)
- (xalloc, smalloc.c interpret.c, efuns.c, object.c) Added check
to prevent the stack from growing into the heap.
- (smalloc.c) Some expected/found magic word logs were reversed.
- (doc/efun) Pulami provided a whole bunch of german translations.
- (efuns.c) to_int() on closures didn't work as advertised
(reported by Pulami)
06-Mar-2002 (Lars Duening) (3.3.179)
- (simulate, interpret.c, gcollect.c) With CHECK_OBJECT_REF, the
driver continually checks the consistency of the list of
destructed objects.
- (doc/efun/get_dir) Updated the manpage and added the german
version (both provided by Pulami).
05-Mar-2002 (Lars Duening) (3.3.178)
- (efuns.c) deep_copy() didn't handle quoted arrays properly (reported
by Gnomi).
- (efuns, func_spec) New efun unquote() (suggested by Gnomi).
- (object, gcollect.c, driver.h) Debug macro CHECK_OBJECT_REF activates
a trace of blueprint allocations/deallocations, to be used to debug
the strange refcount bugs recently encountered (b-020228-0).
04-Mar-2002 (Lars Duening) (3.3.177)
- (prolang.y) Publically inheriting functions which had been inherited
protected before now overrides the earlier inherit (b-020303-1).
- (ptrtable.c) When allocating a new ptable, the .table[] member is
cleared.
- (files.c) New get_dir() flag GETDIR_PATH adds the full absolute
pathname to the returned filenames (suggested by Pulami).
03-Mar-2002 (Lars Duening) (3.3.176)
- (simulate.c) When the driver runs on a fatal error, it calls
the master lfun notify_shutdown() with "Fatal Error" as argument
before it dumps core.
- (configure) Added a check for 'bison -y' when looking for YACC.
- (driver.h, mapping, smalloc) If debug macro CHECK_MAPPING_TOTAL
is defined, ever change in the registered mapping size statistics
is accompanied with a sanity check. If the check fails, a
DEBUG message is generated on stderr. Also added diagnostic
statements to count_mapping_size() in order to find the place where
the mappings statistics is screwed up.
01-Mar-2002 (Lars Duening) (3.3.175)
- (rxcache, ed.c, efuns.c, regexp) Extended the rxcache module
into a wrapper around the regexp structure to hide the actual
regexp implementation behind a simple API (some regexp efuns
still use internal knowledge, though).
28-Feb-2002 (Lars Duening) (3.3.174)
- (simulate, efuns.c, gcollect.c, interpret.c) In addition to the
last uncaught-error trace, debug_info() can now also return
the last error trace in general.
- (mapping, interpret.c, object.c, setting files) The MAX_MAPPING
configuration parameter now determines the total number of
elements (keys + values) a mapping can hold, not just the maximum
number of keys. The current max-mapping settings have been tripled
to account for this change (f-020223).
27-Feb-2002 (Lars Duening)
- (wizlist.c) Efun wizlist_info() now returns the total number
of mappings per user, too.
- (smalloc.c) Corrected the statistics adjustment during the freelist
consolidation.
- (backend.c) The check_alarm() method did not recognize the '--no-heart'
option, eventually turning the alarm() back on (reported by Dafire).
26-Feb-2002 (Lars Duening) (3.3.173)
- (efuns.c) Adjusted the terminal_colour() sanity check to acknowledge
a certain boundary condition; added a test to make sure that
the indentation is smaller than the wrapping width (reported
by Menaures).
- (actions.c) An error in add_action() could cause the driver to free
memory twice (reported by Menaures).
- (mapping.c) An allocation in walk_mapping() didn't check for success.
22-Feb-2002 (Lars Duening) (3.3.172)
- (simulate.c) Made the load_object_error() method resistant
against object names with printf format specifications (reported by
Gnomi).
- (mudlib/uni-crasher) Added Menaures' test object to the archive.
21-Feb-2002 (Lars Duening)
- (array.c) Array-joins didn't work properly because the code
was comparing the wrong values (reported by Dafire).
- (simulate.c) Setting a string driver hook leaked the string.
- (gcollect.c) The refcounts for object and programs names weren't
counted correctly.
- (main, gcollect.c, xalloc.c, smalloc.c) Added a new low-level writes()
function to replace all the macros floating around.
20-Feb-2002 (Lars Duening) (3.3.171)
- (prolang.y) Variable definitions are now normal statements and
as such no longer restricted to the beginning of a block (f-000430-1).
18-Feb-2002 (Lars Duening) (3.3.170)
- (gcollect.c) Oops, forgot to close a comment. Strange though that
my test compile didn't pick this one up (thanks, Dafire!).
17-Feb-2002 (Lars Duening) (3.3.169)
- (prolang.y) In a for() loop, variables may now be declared without
initialisation (e.g. 'for (int i; ...)') (suggested by Pulami).
- (gcollect.c) Since the GC seems to crash when trying to print the
name for destructed leaked objects, I temporarily disabled the
printing of these names so that we can figure out why the object
was leaked in the first place.
- (interpret.c) Corrected a crasher in efun referencep() (reported by
Menaures).
- (call_out.c) Looking up call_outs by closure didn't fully handle
all closure types, causing the driver to fatal (reported by Menaures).
- (efuns.c) Efun clones() didn't check its arguments well enough
(reported by Menaures).
- (random.c) Tentatively modified the scaling of the raw random number
to the desired range so as to avoid overflow problems (investigated
by Collin Baillie for an Alpha machine).
15-Feb-2002 (Lars Duening)
- (simul_efun.c) simul-efuns shadowing real efuns were not properly
discarded, making it impossible to reactivate them (which in a
way was lucky as it made it possible to find the call_other bug).
- (interpret.c) The error handling for a secure call did not
properly roll back the control stack, leaking any closure
referenced from it (b-990505-0).
13-Feb-2002 (Lars Duening) (3.3.168)
- (bitstrings.c) Efun copy_bits(): I accidentally had deleted the lines
handling negative deststart values. The efun was also
prone to numerical overflow effects (reported by Menaures).
- (gcollect.c) Hmm, clear_object_ref() unconditionally cleared
the blueprint reference - this should happen only for
destructed blueprints. Dunno if this was responsible for
the recent crashes in FinalFrontier.
- (sprintf.c) sprintf("%-=10s", "a\nb\n") printed two extra
newlines at the end instead of just one (reported by Gnomi).
11-Feb-2002 (Lars Duening) (3.3.167)
- (Makefiles) Corrected the compilation and call to dftables (reported
by Menaures).
- (comm.c) If on shutdown players were already destructed in
notify_shutdown(), the following remove_player() was passed
destructed objects (reported by Dafire).
- (bitstrings.c) Corrected a crasher in the new efun copy_bits().
- (bitstrings.c) copy_bits() malfunctioned if src range to copy ended
in unset bits (reported by Menaures).
- (efuns.c) In efun terminal_colour(), the wrapping analysis had
to be separated from the initial length gathering since the
analysis requires all lengths to be available. Without the
separation, the driver ran into a fatal sanity error on some
input values (reported by Dafire).
- (actions.c) Argument errors in add_action() would leak the
action sentence.
10-Feb-2002 (Lars Duening) (3.3.166)
- (config.h, autoconf, lex.c) New configuration parameter --use-pcre
(disabled by default) to enable the use of PCRE instead of
traditional regexps. If enable, the LPC macro __PCRE__ is defined.
This is just the basic configuration framework, the PCRE code has not
yet been integrated.
- (pcre/, Makefiles) Included the PCRE code into the driver distribution,
and it is even compiled and linked, but not yet used by the driver.
- (bitstrings, func_spec) New efun copy_bits() to copy ranges of
bitstrings (based on code provided by Menaures).
- (bitstrings.c) And nobody noticed that set_bit() was broken :-)
- (efuns.c) Efun terminal_colour(): In wrapped formatting, when a
word is too long to fit on a line by itself and there are at least
two characters space left on the current line, the long word is begun
immediately. Previously, such long words were always printed on a
line of their own (suggested by Fiona).
07-Feb-2002 (Lars Duening) (3.3.165)
- (ed, comm, efuns) Modified the print_prompt() routine so that
the editor prompt is take directly from the editor buffer.
This allows to get rid of the swapping of editor and normal command
prompts, which may also have been responsible for the memory
leaks reported in b-020205-0 (though I can't prove that). As an
aside, the f_set_prompt() function moved from efuns.c to comm.c .
- (actions.c) If notify_fail() was not used from an undestructed
command giver, the given failure notice value leaked (b-020205-1).
07-Feb-2002 (Lars Duening) (3.3.164)
- (bugs/) Cleaned up the bug reports.
06-Feb-2002 (Lars Duening) (3.3.163)
- (prolang.y, make_func.y, comm.c) New optional driver hook
H_DEFAULT_PROMPT to specify a prompt different from the
usual one.
- (prolang.y, make_func.y, comm.c) New optional driver hook
H_PRINT_PROMPT to do special magic when printing a prompt
(suggested by Markus Peter).
- (sprintf.c) In justified column formatting, when a word is too
to fit on a line by itself and there are at least two characters
space left on the current line, the long word is begun immediately.
Previously, such long words were always printed on a line of
their own (suggested by Fiona).
06-Feb-2002 (Lars Duening) (3.3.162)
- (bugs) Added more information about memory leaks.
05-Feb-2002 (Lars Duening) (3.3.161)
- (prolang.y) Inherited public but undefined function were hidden
by (simul-)efuns of the same name, making a resolution by
crossdefinition through another inherited module impossible
(reported by Fiona).
03-Feb-2002 (Lars Duening) (3.3.160)
- (simulate, prolang.y, lex.c) Added a limit safety check to
limit_error_format(), and increased the buffer sizes for the
error messages (reported by Gnomi).
01-Feb-2002 (Lars Duening)
- (efuns.c) Removed the undocumented 'feature' that a process_string()
function call specification could be terminated with a space.
- (array, prolang.y, interpret.c) The '|' operator can now join
arrays.
31-Jan-2002 (Lars Duening) (3.3.159)
- (interpret.c) If input_to() was used without command giver,
a NULL pointer string was pushed onto the interpreter stack
due to a missing check in the privilege_violation4()
function (reported by Menaures).
30-Jan-2002 (Lars Duening) (3.3.158)
- (gcollect.c) The GC forgot to clear the refcounts in the known
destructed objects, thus sometimes causing a 'First reference
to program, but refcount != 0' fatal error (reported by Coogan,
reproduced by Menaures).
- (object.c) replace_program() without argument can now skip
the extra inherits added by the compiler to accomodate
virtual variables (reported by Nathan).
26-Jan-2002 (Lars Duening) (3.3.157)
- (prolang.y) The wildcarded supercall "*":: no longer throws an
error if none of the inherited objects defines the called function.
It fits into the semantics of the '*' wildcard ("any or none"), and
it is practical for supercalls like "*"::reset() (suggested by
Zonk@Finalfrontier via Dafire).
25-Jan-2002 (Lars Duening) (3.3.156)
- (object.c) Made an error message more informative.
24-Jan-2002 (Lars Duening)
- (interpret.c) If a value of the wrong type is passed to a switch,
the driver no longer throws a runtime error but instead
jumps to the 'default' case (suggested by Pulami).
23-Jan-2002 (Lars Duening) (3.3.155)
- (prolang.y) The '::' operator did not recognize the separate
namespaces of local variables and functions (reported by
Imp via Gnomi).
- (func_spec, prolang.y, interpret.c) Added new bytecode instruction
nconst1 and create negative number constant right at compile
time instead of using negate() - especially useful for __INT_MIN__
(reported by Menaures).
- (efuns.c, interpret.c, mapping.c) check_map_for_destr() wasn't
called before copying or subtracting mappings (reported by Coogan).
- (simulate.c) Improved the loadtime error messages: they now print
the inheritance chain (suggested by Gnomi).
- (etc/memusage) Provided by Fiona - thanks!
17-Jan-2002 (Lars Duening) (3.3.154)
- (simul_efun, simulate.c) Destructing the simul-efun object
immediately invalidates all simul-efuns; this should reduce
the number of 'undefined function' errors when doing manual
reloads of the simul-efun object.
- (smalloc.c, prolang.y, closure.c) Modified some memory accesses
in order to keep Memory Check tools like ZeroFault happy.
- (regexp.c) The .from_ed member in a newly compiled regexp
wasn't set.
- (object.c) One variable wasn't set.
16-Jan-2002 (Lars Duening)
- (simul_efun) When reloading the simul-efun objects, all previous
sefuns are discarded and removed from the symbol table. Otherwise
if the simul-efun object used cross-defined sefuns itself, the
recompiled object would not recognize the cross-defined calls
and instead pick up the older inactive entry from the symbol
table. This problem may still occur when reloading a simul-efun
object by hand (reported by Coogan and some other people).
- (lex) Inferior identifier entries now have their own string
reference.
- (lex.h, prolang.y) The magic values for ident_t.u.global now
have symbolic names.
15-Jan-2002 (Lars Duening)
- (configure) Fiona did more analysis on the rxcache hash and found
out that using a prime table size doesn't help. I set the size back
to 8192; let's see how bad the collisions are at this small table
size.
14-Jan-2002 (Lars Duening)
- (interpret.c) The overflow error messages for float divisions
named the wrong values (thanks, Guandalug!).
12-Jan-2002 (Lars Duening) (3.3.153)
- (configure.in) Fiona pointed out that just halving the rxcache
size doesn't seem to increase the fill ratio. As an experiment
I now set the default size to prime 8191.
- (efuns.c, interpret.c) The float range checks stupidly compared against
DBL_MIN for the low limit instead of -DBL_MAX (reported by Ben).
- (mstrings.c, efuns.c) Added string table related statistics.
10-Jan-2002 (Lars Duening) (3.3.152)
- (lex.c) Added new predefined macros __FLOAT_MIN__ and __FLOAT_MAX__
for the float value limits.
- (interpret.c, efuns.c) Added checks for numeric overflows to float
operations. Btw, <int> / <float> returned a wrong result.
- (configure.in) Reduced the default size of the RXCACHE table to 8192
instead of 16384 entries.
08-Jan-2002 (Lars Duening) (3..3.151)
- (efuns.c) Efun terminal_colour() removed a crasher which happened
when too many control sequences appeared in a line (reported by Peng).
- (autoconf/configure.in) Added icc compiler option '-ipo' to highest
optimisation tests.
- (make_func.y, bitfuns.c, comm.c, lex.c, interpret.c) Removed a couple
(but not all) warnings generated by the Intel Compiler (reported by
Dafire).
03-Jan-2002 (Lars Duening) (3.3.150)
- (gcollect.c) Forgot to clear the refcounts in the list of
destructed objects. Oops.
- (object.c) free_prog() now also frees its blueprint reference, which
should remove at least one major refcount leak.
- (lp-245/obj/master.c, lp-245/obj/player.c) Small corrections.
02-Jan-2002 (Lars Duening) (3.3.149)
- (simulate, comm.c) Corrected a potential crasher when bad arguments
are passed to efun input_to(): the embedded callback structure
wasn't initialized properly, so that the free_input_to() got
garbage data instead of pointers (reported by Menaures).
- (util/xerq/erq.c) Reduced the amount of crap printed in DEBUG
configuration.
- (gcollect.c) There seems to be a problem with leaking object refcounts,
so that destructed objects are tagged as 'referenced' even if they
aren't. The GC will eventually free the memory itself, but inavoidably
mess up the object statistics. As a first measure the GC after
the mark phase checks the list of destructed objects if any
of the objects on it haven't been referenced yet. If so, the
objects concerned are logged and then explicitely included into
the list of objects to free. This way at least the object statistics
will be kept in sync for the time being.
02-Jan-2002 (Lars Duening) (3.3.148)
- (gcollect.c, simulate, comm) The GC now removes all stale objects
referenced from the interactive structures during the cleanup phase.
As a side effect, callbacks may no longer reference destructed
objects during the clearing/counting phase of a GC.
- (actions, main.c, backend.c, efuns.c, gcollect.c, interpret.c,
simulate, dumpstat, string_spec, mudlib/sys/debug_info) Destructed
objects are now kept in a separate list in order to aid mudadmins in
analysing the memory usage of their muds. debug_info(DINFO_STATUS)
returns the statistics in the new fields DID_ST_OBJECTS_NEWLY_DEST
and _DEST; debug_info(DINFO_DUMP, "destructed") dumps the lists to a
file; and the builtin commands 'status tables' and 'dumpallobj' have
been updated accordingly.
31-Dec-2001 (Lars Duening) (3.3.147)
- (efuns.c) to_string() can now handle operator closures (suggested
by Gnomi).
30-Dec-2001 (Lars Duening) (3.3.146)
- (interpret.c) abs(INT_MIN) now generates an overflow error (reported
by Menaures).
- (sprintf.c) When adding columns, a one-line column ending with a
newline inserted the newline on-the spot instead of delaying
it until the end of the line as it was done with multiline
columns (reported by Gnomi).
29-Dec-2001 (Lars Duening)
- (driver/dumpallobj, efun/debug_info) Explained the format of
the OBJDUMP file.
- (settings/tubmud) Updated (thanks, Coogan!)
28-Dec-2001 (Lars Duening) (3.3.145)
- (interpret.c) When calling a simul_efun in a vanished object, the
local stackpointer of eval_instruction() was not synchronized
with inter_sp after the call (reported by Gnomi).
- (simul_efun.c) When reloading a simul_efun object, the check for
old sefuns to reactivate ignored changes in the TYPE_MOD_XVARARGS
flag. Since the exact format of the F_SIMUL_EFUN instruction depends
on this flag, this could trip the bytecode interpreter (reported by
Gnomi).
- (mudlib/astar.c) An implementation of the A* pathfinding algorithm,
donated by Acius (thanks!).
21-Dec-2001 (Lars Duening) (3.3.144)
- (simulate.c) When checking the refcounts, the extra_refs in objects
named in callbacks weren't counted corrected (reported by Tomba).
- (gcollect, call_out.c, simulate.c) Removed knowledge about the
GC internals from call_outs and callbacks.
20-Dec-2001 (Lars Duening) (3.3.143)
- (mapping.c) The handling of protected deleted entries did create
some dead links (reported by Tomba).
19-Dec-2001 (Lars Duening) (3.3.142)
- (object.c) Efun say(): one variable was initialized wrongly,
occasionally causing the driver to crash (reported by Nostradamus).
14-Dec-2001 (Lars Duening) (3.3.141)
- (interpret.c) Efun set_this_object() queried the master and
simul-efun object without checking if they actually exist.
- (autoconf, main, comm.c, backend.c) The input escape character
can now be configured to something else than '!' (suggested
by Tomba).
- (settings/bat) New settings for BatMUD.
12-Dec-2001 (Lars Duening) (3.3.140)
- (call_out.c) Efun call_out_info() did not return the target object
if the call_out is a closure (reported by Menaures).
- (interpret.c) The increment and decrement operators were missing the
overflow checks (reported by Freaky).
- (lex.c) New LPC defines __INT_MAX__ and __INT_MIN__ for the numeric
integer limits.
- (interpret.c) Another overflow check, this time for __INT_MIN__ / -1
(reported by Menaures).
- (object.c) Corrected the bugfix to the say() refcount problem
(thanks, Tomba!)
11-Dec-2001 (Lars Duening)
- (comm.c) TELOPT_TM can now be negotiated from the mudlib as well
(reported by Peng).
11-Dec-2001 (Lars Duening) (3.3.139)
- (interpret.c) Additions, subtractions and multiplications now
check for numeric overflows.
11-Dec-2001 (Lars Duening) (3.3.138)
- (interpret.c, mapping.c) Oops, the new checks also introduced
divisions by 0 (reported by Menaures).
- (sprintf.c) Runtime fieldsize specification by '%*' didn't check
if the size was given as MIN_INT: it would try to negate it
to get the positive number, but fail and cause the formatting
routines to crash under circumstances (reported by Menaures).
10-Dec-2001 (Lars Duening) (3.3.137)
- (interpret.c) gcc 2.91 on Linux/x86 generates buggy code for
MIN_INT % -1, so this case is now explicitely check for
(reported by Menaures).
- (interpret.c) Multiplication of a string with a number was
not checked for numeric overflows in the computation of
the result length (reported by Menaures).
- (smalloc.c) Added a check against numeric overflows in the
computation of the final memory block size.
- (mapping.c) When allocating/resizing mappings, a check against
numeric overflows in the size computations has been added
(reported Menaures).
05-Dec-2001 (Lars Duening) (3.3.136)
- (backend.c) Before calling reset() or clean_up() from the backend,
the previous_object is cleared (reported by Gnomi).
- (main.c) New commandline option:
--random-seed <num>
Seed value for the random number generator. If not given, the
driver chooses a seed value on its own.
This option is for debugging.
- (interpret.c) The mysterious code in calling alien lfun closures to
create a second control frame, deactivated in 3.3.83, revealed
its purpose: when for such a closure the bound object l->ob
differs from the code object l->function.alien.ob, this fact
needs to be recorded in order to prevent security holes. So the
code fragment has been activated again with a small change: the
second control frame will be created only if the two objects
differ (unknowingly suggested by Menaures).
04-Dec-2001 (Lars Duening) (3.3.135)
- (interpret.c) When doing a call_other on an array, inter_sp
was incorrect while getting the object. An error there
then could clobber memory.
- (backend) Added in internal flag 'mud_is_up' for debugging.
- (main.c) The initial random seed is printed for debugging
purposes.
29-Nov-2001 (Lars Duening) (3.3.134)
- (prolang, lex.c) Storing the line number info for the end of an
include file used the wrong line for rollbacks (reported by
Guandalug).
28-Nov-2001 (Lars Duening) (3.3.133)
- (prolang.y) Another correction to the bugfix of Gimli's problem
(reported by Freaky).
27-Nov-2001 (Lars Duening) (3.3.132)
- (prolang.y) The bugfix to Gimlis problem unfortunately broke a couple
of muds. This version works better (reported by many people).
- (object.c) Removed memory leaks in the error handling of include_list()
and inherit_list().
25-Nov-2001 (Lars Duening) (3.3.131)
- (mudlib/sys/functionlist.h) Changed the <> include of lpctypes.h
into a "" include (suggested by Heiko).
- (prolang.y) Inheriting two private functions of the same caused the
compiler to crossdefine the second one to the first. Not directly
visible to the user, this messed up any use of these functions
by INITIALIZATION_BY___INIT (reported by Gimli).
- (object.c) Efun replace_program() can omit the argument if the
object has only one inherit (suggested by Pulami).
24-Nov-2001 (Lars Duening) (3.3.130)
- (lex.c) The auto-include strings needed to be prefixed with a newline
internally - yet, the newline was added after the string (reported
by Heiko).
23-Nov-2001 (Lars Duening)
- (object.c) Efun say() could leak object references (reported by Tomba).
- (mudlib/sys/functionlist.h) Changed the absolute include of lpctypes.h
into a <> include (suggested by Heiko).
21-Nov-2001 (Lars Duening)
- (pkg-mysql.c) Using the mysql->thread_id as handle proved to be
unreliable as the thread_id may change. Instead an explicit
handle is now used (thanks, Fuchur!).
- (ed.c) Added command 'T' to perform Tab <-> Whitespace conversion
(thanks, Menaures!).
20-Nov-2001 (Lars Duening) (3.3.129)
- (sprintf.c) Printing a table modified the internal precision information
without making a backup. If now the table was applied to an array
of data ("%#99999999999@s" format string), formatting the second
line would cause a crash (reported by Menaures).
- (doc/efun/snoop) Corrected the manpage: snooping an already snooped
player terminates the previous snoop (reported by Zordiac).
20-Nov-2001 (Lars Duening) (3.3.128)
- (exec.h, lex.c, prolang, object, gcollect.c, typedefs.h) Added
complete include file information to compiled programs.
- (object.c) Implemented efun include_list() properly.
19-Nov-2001 (Lars Duening) (3.3.127)
- (sprintf.c) It was possible to instruct sprintf to format a string
as both columns and as a table. sprintf() then formatted it as
columns, but any error (like buffer overflow) would crash the
driver. The error recovery is now more robust, and such an invalid
format string is rejected (reported by Menaures).
- (sprintf.c) Max size of the result is now 128 KByte.
- (lex.c) A H_AUTO_INCLUDE closure also receives a flag telling if
it was a <>-type include or not (suggested by Freaky).
- (bitstrings.c) Efuns and_bits(), or_bits(), xor_bits() mishandled
the bits 5, 11, 17, ... (thanks, Fuchur!)
- (prolang.y) The bugfix yesterday was not quite correct: a pair
of missing parentheses completely changed the meaning of the
check for private inherited functions, causing the driver to crash
(reported by Freaky).
18-Nov-2001 (Lars Duening) (3.3.126)
- (object.c) Efun inherit_list: the tagging of virtual inherits
returned a random value for the main program (reported by Freaky).
- (prolang.y) Inherited private functions could hide simul-efuns
or efuns (reported by Gnomi).
- (lex.c) If H_AUTO_INCLUDE is set to a closure, it will be called
for all files opened by the lexer. A second argument passed to
the closure determines whether the call is for the object file
itself or for an included file (suggested by Freaky).
- (func_spec, array, exec.h, prolang.y) New efun include_list()
to return the filenames read when compiling a program.
- (efuns.c) Added the number of included files to the result
of object_info(OINFO_MEMORY).
17-Nov-2001 (Lars Duening) (3.3.125)
- (func_spec, prolang.y, make_func, lex, simulate) Replaced the efun
set_auto_include_string() with the driver hook H_AUTO_INCLUDE.
Additionally, a closure can be used to generate the auto include
data (f-000505, f-011026-2, f-990316-1).
- (simulate.c) Removed a small memory leak in set_driver_hook():
replacing hooks leaked the old hook data.
- (comm) Efun input_to() now accepts a prompt parameter, specifying
the prompt to print.
- (object.c, exec.h, mudlib/sys/inherit_list.h) New flag for efun
inherit_list() allows to tag virtual inherits in the result
(rest of f-991020-0).
- (doc/concepts/hooks) Corrected the docs for the MODIFY_COMMAND hooks.
16-Nov-2001 (Lars Duening) (3.3.124)
- (sys/debug_info.h, smalloc.c) Efun debug_info(): macro DID_SBRK_SIZE was
typoed as DID_SBKR_SIZE.
- (sys/debug_info.h, smalloc.c) Efun debug_info(): added the derived
statistics DID_MEM_ALLOCATED, _USED and _TOTAL_UNUSED to the
DINFO_DATA:DID_MEMORY data.
- (interpret.c) The stack overflow error handling forgot to update
the stack pointer after cleaning up the stack, causing some
svalues to be freed twice (reported by Coogan).
- (efuns.c) Efun terminal_colour(): Temporary values are no longer
held directly on the stack, but instead in an array on the stack,
thus greatly reducing the stack usage for strings with lots of
colour codes.
15-Nov-2001 (Lars Duening) (3.3.123)
- (svalue.h) The definition of macros push_object() and
push_valid_object() lacked the 'from' argument (reported by Nathan).
- (lex.c) If H_INCLUDE_DIRS is set to an array of directory names,
the names can now have leading '/' (reported by Nathan).
- (interpret.c) Improved the stack overflow checking a bit, and for
some function calls the local variables were allocated twice.
- (efuns.c) member() used with closures didn't always find them
(reported by Gnomi).
14-Nov-2001 (Lars Duening) (3.3.122)
- (gcollect.c) Tweaks to the information dumped on fatals.
- (driver.h, gcollect) New debug macro DUMP_GC_REFS (in driver.h)
instructs the GC to list all found references on the gcollect_outfd.
Off by default, this macro should be defined only by people
getting fatal()s like 'First reference to destructed object, but
ref count != 0'.
- (main) New function dprintf4().
- (mapping.c) compact_mappings() did not remove destructed elements
from the mappings (reported by Menaures).
- (efuns.c, interpret.c) Put back in some of the check_map_for_destr()
calls, as they are required in order to get an accurate count
of the number of entries.
13-Nov-2001 (Lars Duening) (3.3.121)
- (gcollect.c, smalloc.c) Removed a compilation problem when
MALLOC_LPC_TRACE is not defined (reported by Menaures).
- (efuns.c, interpret.c, sprintf.c) Removed unnecessary calls
to check_map_for_destr().
- (smalloc.c) The computation of a 'magic' word in the freelist
consolidation was wrong, causing bus errors in Tubmud.
- (files.c) Added missing newlines to some error messages
(thanks, Freaky!)
- (object.c) Efun transfer() miscalculated the weights when the
target wasn't a living (reported by Zordiac).
- (interpret.c) When calling a #'efun which takes another efun as
default argument, call_lambda() generated incorrect bytecode
in the trampoline stub by assuming that instruction code
equalled bytecode. Example: funcall(#'ctime) (reported by Dan).
12-Nov-2001 (Lars Duening) (3.3.120)
- (make_func.y) Lexer now understands lines terminated with CRLFs
instead of just LFs (reported by Holger).
- (mapping.c) Adjusted the computation of num_dirty_mappings in
remove_empty_mappings(). This should the fix the inconsistency
in this counter (thanks, Andre and Carsten!)
- (gcollect.c, xalloc) When a 'First ref to' with unmatching refcount
is encountered, the memory allocation information is dumped, too.
24-Oct-2001 (Lars Duening) (3.3.119)
- (efuns.c) If a closure is used with regreplace(), it will be
passed the position of the found substring, too (suggested
by Alfe).
- (comm.c) New efun remove_input_to() (part of f-000530).
23-Oct-2001 (Lars Duening)
- (doc/efun/terminal_colour) Improved the explanation of the key
recognition strategy, and added a MudOS simulation function
courtesy of Fiona.
22-Oct-2001 (Lars Duening)
- (md5.c) Changed two function calls from the generic to the MD5
versions (thanks, Gawain!)
21-Oct-2001 (Lars Duening) (3.3.118)
- (actions.c) Removed a crasher when add_action() was performed between
two objects with no environment (thanks, Fuchur!).
18-Oct-2001 (Lars Duening) (3.3.117)
- (doc/LPC/arrays, doc/efun/sprintf) Improved examples by
Coogan (thanks!).
- (sprintf.c) Removed a crasher in justified formatting when the string
to format contained only one word (reported by Slava and Coogan).
17-Oct-2001 (Lars Duening) (3.3.116)
- (interpret.c) I had to deactivate the tests against assignments
to negative ranges - this feature is in fact in use (thanks,
Coogan and Alfe - and sorry for breaking TubMud!).
15-Oct-2001 (Lars Duening) (3.3.115)
- (interpret.c) Another error in call_other() on arrays of objects.
(reported by Dafire)
- (call_out.c) The minimum delay can now be 0 (suggested by Tomba).
14-Oct-2001 (Lars Duening) (3.3.114)
- (efuns.c) Removed a free-memory access in efun strstr() (thanks,
Tomba!)
- (Makefiles) Updated my MkDepend tool, so that it no longer adds
non-existing include files to the dependencies.
- (interpret.c) Oops, call_other()/call_direct() on array of objects
always used default functions even if they shouldn't. This also
caused the double freeing of svalues. (reported by Dafire)
- (interpret.c, swap.c, xalloc) Didn't compile when using sysmalloc
as allocator (reported by Tomba).
12-Oct-2001 (Lars Duening) (3.3.113)
- (sprintf.c) Improved the flushing algorithm: spaces are more
evenly distributed, newlines in columns didn't work properly
(reported by Slava).
- (make_func, func_spec, interpret, simulate, lex) Implemented
the optional H_DEFAULT_METHOD driver hook to implement
default methods for unresolved calls.
- (lots of files) Renamed closure_hook[] to the more sensical
driver_hook[]. And got rid of USE_FREE_CLOSURE_HOOK.
- (erq, xerq) Erq now accepts an '--execdir' argument to override
the default ERQ_DIR setting (suggested by Freaky).
- (main, comm.c) It is now possible to pass simple arguments to the
erq with the --erq commandline option (suggested by Freaky).
11-Oct-2001 (Lars Duening) (3.3.112)
- (sprintf.c) New formatting modifier '$' allows flush formatting
of strings and columns of strings (f-010717).
- (interpret.c) Added the apply framework for default methods.
10-Oct-2001 (Lars Duening) (3.3.111)
- (object.c) Efun inherit_list() can now return the inheritance
structure as a tree (part of f-991020-0).
- (interpret.c) Simul-efuns with an varargs argument as weren't able
to receive no extra arguments (reported by Tomba).
09-Oct-2001 (Lars Duening) (3.3.110)
- (gcollect.c) Increased the refcount of an destructed referenced
object before recursing into the substructures - I have the
feeling that there was a possible race condition, but I can't
prove it.
- (object) Efun function_exists() can now also return the filename
and linenumber where a function was defined (based on a patch
p-010928-0 by Andre).
- (object.c) Removed the fixed table in inherit_list() and replaced
it by a pooled list. It also already gathering the information
about the shape of the inheritance tree.
08-Oct-2001 (Lars Duening) (3.3.109)
- (prolang.y) Function definition errors and warnings now all print
the name of the function involved (suggested by Freaky).
- (simulate.c) Shadowing a nomask function now prints the names of
objects involved as well (suggested by Freaky).
06-Oct-2001 (Lars Duening) (3.3.108)
- (prolang.y) Warnings about redefinition of visibility apply
to prototype/functions only, but no longer to redefinitions
of inherited functions.
05-Oct-2001 (Lars Duening)
- (lex.c) Termination of a macro definition in an include file
with End-of-file confused the lexer (reported by Tomi).
- (comm) If a message had to be discarded due to contention (EWOULDBLOCK),
the user will receive a information message at the next possible
opportunity.
- (comm.c) Efun binary_message() wrote random data (thanks, Andre!).
04-Oct-2001 (Lars Duening) (3.3.107)
- (efuns, md5) Renamed efun md5_encrypt() to md5(), and added a new,
Apache compatible password encryption efun md5_crypt (provided by
Dafire).
03-Oct-2001 (Lars Duening) (3.3.106)
- (prolang.y) Prototypes no longer modify the definition of inherited
functions in strange ways (reported by Fiona).
01-Oct-2001 (Lars Duening) (3.3.105)
- (prolang.y) The check for redefinition of 'nomask' functions no longer
worked (reported by Gimli).
30-Sep-2001 (Lars Duening) (3.3.104)
- (lex.c) Added a warning about empty #pragmas (reported by Slava).
- (interpret.c) Tracing no longer crashes when the command_giver
turns non-interactive (reported by Dafire).
28-Sep-2001 (Lars Duening) (3.3.103)
- (lex.c) Spaces before the lineend caused the lexer to complain about
an unrecognized pragma, even though the pragma had been recognized
(reported by Dafire and Slava).
- (efuns.c) Efun terminal_colour(): The escape sequence '%%^^' is
now recognized and replaced by '%^' as is '%^%^' already. This is
for compatibility with MudOS drivers (suggested by Fiona).
- (telnet.h, comm.c) Added support for mudlib negotiation of MCP, MSP
and MXP through the normal H_TELNET_NEG hook (suggested by Markus
Peter).
- (interpret.c, lex.c, smalloc.c) Made it work on Linux s/390 (a machine
where char's are by default unsigned) (provided by Freaky).
27-Sep-2001 (Lars Duening) (3.3.102)
- (lex.c) Pragma recognition no longer stumbles over CRs at the line
end (reported by Freaky and Slava).
- (interpret.c) The idiom of assigning to a range [i..i-1] in order to
insert elements is legal again - a lot of mudlibs already use it
(reported by Andre).
26-Sep-2001 (Lars Duening) (3.3.101)
- (interpret.c) Assignments to negative length ranges (eg. [3..2]) are
caught and throw an error (reported by Gimli).
- (gcollect.c) Printing memory information during a GC is more robust
against string NULL pointers (reported by Freaky).
- (lex.c) It is possible to specify multiple pragmas in one #pragma
statement, separated by commas (suggested by Largo).
08-Sep-2001 (Lars Duening) (3.3.100)
- (interpret.c) The test if a function call should be trace or not
was done against the command_giver, not against the
current_interactive as documented (reported by Gnomi).
- (simulate.c) When entering a fatal(), the given format string is
printed as is to stderr (just a precaution).
- (smalloc.c) The 'magic match' failed messages now give the expected
block address and sizes, too.
- (lex.c) Added warning when an unknown pragma is encountered (suggested
by Robert).
05-Sep-2001 (Lars Duening) (3.3.99)
- (prolang.y) The driver couldn't handle (multiple?) second-level inherits
of a 'private nomask' function, which inline closure now are (reported
by Bardioc).
03-Sep-2001 (Lars Duening) (3.3.98)
- (xalloc, smalloc) New helper function dump_malloc_trace() to, well, dump
the malloc trace if there is one.
31-Aug-2001 (Lars Duening) (3.3.97)
- (lex.c) The lfuns implementing inline closures are now 'private nomask',
which is the real solution unlike the one implemented in
3.2.9-dev.260/3.3.39 (suggested by Freaky).
- (efuns.c) If terminal_colour() was used with a closure returning a
computed string, the ever call (but the first) within the same
formatting clobbered the result from the previous one (reported by Ben
and Elric).
- (swap.c) Oops, when adjusting the allocation statistics after
swapping out variables, the driver occasionally tried to dereference
a non-existing pointer (reported by Ben and Nostradamus).
- (mudlib/sys/lpcytpes.h) The values to be returned by functionlist() were
out of sync with what functionlist() really returned (reported by
Freaky).
29-Aug-2001 (Lars Duening) (3.3.96)
- (smalloc.c) Corrected a small statistics problem in the
freelist consolidation: some unusable space was counted
twice (b-010713-0, b-000830).
- (swap.c) When swapping variables, the object allocation size
statistics wasn't updated.
- (lex.c) Multi-dimensional array indices in macro calls are no longer
confused with multiple macro arguments (reported by Freaky).
- (files.c) Trying to read 0 bytes with read_bytes() caused a
fatal error.
- (mapping.c) Corrected errors in the statistics.
28-Aug-2001 (Lars Duening) (3.3.95)
- (interpret.c) Oops, one string argument was passed in the
wrong way.
28-Aug-2001 (Lars Duening) (3.3.94)
- (interpret.c) More corrections to the refcount checking code.
Furthermore, an failure no longer crashes the driver (but
generates lots of debugging output)
(reported by Tomba).
- (pkg-mysql.c) Removed a memory leak caused by the result set
not begin freed after all the data has been fetched.
- (backend.c) Added safeguard so that slow_shut_down() is not
called repeated while a previous one is still pending (suggested by
Dafire).
28-Aug-2001 (Lars Duening) (3.3.93)
- (interpret.c) The reference loop check was too strict and also
flagged legal assignments (thanks, Dan).
27-Aug-2001 (Lars Duening) (3.3.92)
- (interpret.c) Improved the check for reference loop creation on
assignment (suggested by Menaures).
- (many files) When reloading the master object, the driver freed
through the driver hooks some object references it shouldn't free.
If a lambda driver hook is bound to an object, this reference is
now counted. This makes rebinding the hook closure a bit more
laborsome, but overall the handling is safer since consistent
(reported by Tomba).
26-Aug-2001 (Lars Duening) (3.3.91)
- (interpret.c) Efun sscanf() didn't check its arguments (reported by
Tomba).
- (simulate.c) Running the driver with '-d -d' crashed it when loading
objects.
- (interpret.c) The refcount check for got to count the blueprint
reference in programs (reported by Tomba).
- (smalloc.c) The check against MAX_MALLOCED was incomplete and
could lead to use of foreign memory (reported by Menaures).
25-Aug-2001 (Lars Duening)
- (prolang.y) The range checks for the new [>] indexing were not complete
(reported by Tomba).
23-Aug-2001 (Lars Duening) (3.3.90)
- (array.c) ERQ callbacks for a destructed object don't have a
current_object at the time the error occurs. The error handling code
allocates an array, but the array code was still assuming that
current_object is always valid (reported by Fiona).
- (prolang.y) Redefining an inherited private function with a non-private
one, and then inheriting the redefinition didn't work (reported by
Menaures).
22-Aug-2001 (Lars Duening) (3.3.89)
- (interpret.c) The lambda protection had a bug: when a non-lambda closure
was called from within an executed lambda, the lambda closure was
accidentally freed (reported by Fiona).
- (sprintf.c) *blush* I completely forgot to add the terminator 0 after
creating the quoted representation of a string (thanks, Menaures!).
21-Aug-2001 (Lars Duening) (3.3.88)
- (prolang.y) The 'private' correction caused the driver to crash
under obscure circumstances. I implemented the correction now
in a different way, and it seems to work now (reported by Bardioc and
many others).
- (prolang.y) If an efun was called with too many arguments, the
extraneous args were popped twice from the argument stack, so that
subsequent function calls clobbered memory (reported by Dafire).
- (simulate.c) Added an error when the time left for a catch() is less
than the reserved cost.
19-Aug-2001 (Lars Duening) (3.3.87)
- (prolang.y) Defining a function which is also a private function in an
inherited object no longer redefines the inherited one (reported by
Bardioc and Menaures).
- (sprintf.c) Closures on inherited lfuns are printed with the defining
program for the %O format.
- (sprintf.c) New format specifier 'Q' acts like 'O', except that special
characters in strings are quoted (suggested by Menaures).
15-Aug-2001 (Lars Duening) (3.3.86)
- (interpret.c) Holding a reference on a lambda works much better
if the code actually increment the correct refcount.
14-Aug-2001 (Lars Duening) (3.3.85)
- (interpret) The VM now holds a reference on a lambda while it is
executed, preventing premature destructions (reported by Dan
and Fiona).
- (simulate, actions.c, backend.c, comm.c, gcollect.c) Since the VM
now protects lambdas during their execution, the free_closure_hooks()
hack is no longer needed. For now, the code has been just
deactivated.
- (efuns.c) Corrected late-night errors in efuns ceil() and floor()
(reported by Niels).
13-Aug-2001 (Lars Duening)
- (mapping.c) Adding a mapping to itself via 'm += m' freed svalues
first, then used them as data for assignment (reported by Patryn).
12-Aug-2001 (Lars Duening)
- (func_spec) Somehow the change for sizeof() didn't make it into
the distribution (reported by Menaures).
07-Aug-2001 (Lars Duening) (3.3.84)
- (lex.c) The recognition of numeric character constants was slightly
wrong (thanks, Fiona).
06-Aug-2001 (Lars Duening)
- (object.c) Efun program_name() now accepts 0 as
argument and pass it through (suggested by Niels).
- (func_spec, efuns.c) Efuns floor() and ceil() also accept integers
values (suggested by Niels).
05-Aug-2001 (Lars Duening) (3.3.83)
- (mstrings.h, interpret.c) The duplication of shared strings before
a modification did not catch shared untabled strings. And the memory
usage was calculated off-by-one, too (reported by Niels).
- (simulate.c) Destructing an object with a single shadow crashed the
driver (reported by Craig).
- (object.c) Efuns load_name() and object_name() now accept 0 as
argument and pass it through (suggested by Niels).
- (interpret.c) Calling an alien-lfun created two control frames instead
of just one, with no obvious purpose. I removed one of the frames
but commenting out the code, so if it is needed nonetheless, it
will be easy to reactivate (reported by Niels).
- (interpret.c) For the first 255 simul-efuns it is now permissible to
receive references in a varargs parameter, e.g. to implement
a simulated call_other(). Handle with care! (reported by Coogan)
- (configure) Improved the search for mySQL libraries - it is amazing in
how many different ways this package is installed.
01-Aug-2001 (Lars Duening) (3.3.82)
- (prolang.y) The error message for the case that a wildcarded super
call tried to pass arguments was confusing (reported by Gimli).
- (interpret.c) Efun sizeof() can be used on strings (suggested by Niels).
31-Jul-2001 (Lars Duening) (3.3.81)
- (pkg-mysql.c) Fixed a syntax error. It sucks that I can't compile
this file at home, doesn't it?
- (lex.c) A preprocessor statement following a macro redefinition
wasn't recognized because the macro parsing code clobbered
the newline character (thanks, Fuchur!).
26-Jul-2001 (Lars Duening) (3.3.80)
- (lex.c) The redefinition of a macro messed up the list of defines,
eventually crashing the driver (reported by Freaky).
- (efuns.c) Using terminal_colour() with a closure as lookup method
an a non-tabled keyword crashed the driver (reported by Elric).
- (simulate.c) Clones no longer inherit the current O_WILL_CLEAN_UP
flag from their blueprint - it didn't make sense (thanks, Niels!).
25-Jul-2001 (Lars Duening) (3.3.79)
- (sprintf.c) Printing numbers with leading zeroes and a sign character
printed the sign in the wrong place (reported by Dafire).
- (backend.c) The check_alarm() function did not quite work right
(thanks, Coogan!).
- (efuns.c) Efun regreplace(): Pattern which could match on the
empty string matched once too often at string end.
E.g. regreplace("blah fasel", ".*", "ERSATZ", 1) returned
"ERSATZERSATZ" instead of just "ERSATZ" (thanks, Fiona!).
- (lex.c) Redefinition of a macro yields a warning even if the
definition doesn't change (suggested by Gnomi).
- (backend.c, simulate.c) The initial setting of the O_WILL_CLEAN_UP flag
checked for the hardcoded "clean_up" lfun instead for what the
H_CLEAN_UP hook said. Also, the documentation was slightly out
of sync with the reality (thanks, Niels).
- (mysql.c) db_error() used a non-existing argument (thanks, Dafire!).
17-Jul-2001 (Lars Duening) (3.3.78)
- (array, gcollect.c, mapping) The GC now recounts the number of arrays
and mappings in the game (reported by Niels).
- (prolang.y) If the compiler detects a function call with too many
arguments, the subsequent argument type checks were wrong
(reported by Fiona).
- (sprintf.c) Instead of using the new modifier '$', the efun now
uses the existence of an explicite pad string specification
as flag whether to remove pad space before new lines or not.
This is actually more logical to use than a modifier (suggested
by Largo).
- (actions.c) The special command 'malloc' now follows the
'is_wizard' handling of the other special commands (thanks,
Niels).
16-Jul-2001 (Lars Duening) (3.3.77)
- (mapping.c) Removed an extraneous increment in the mapping statistics:
the hash part of a new mapping was counted twice.
- (lp-245/) Removed the uses order_alist() from the simul_efun objects.
- (func_spec, lex.c, prolang.y, interpret.c, closure.c) Added [>]
indexing method (both single and ranges) to fully replace the
gone extract() efun.
- (make_func.y, lex.c, func_spec) Closure operators can now be declared
directly in the func_spec; no need for manual patching by lex.c .
- (gcollect.c) Oops. Freeing a circular array reference with
MALLOC_LPC_TRACE enabled crashed the driver in the dump
of the array contents.
15-Jul-2001 (Lars Duening) (3.3.76)
- (actions, simulate) Removing or destructing a shadow now properly
removes all associated actions (reported by Nathan).
- (actions.c) New add_action() flag AA_IMM_ARGS implements the sane
NOSPACE argument handling.
15-Jul-2001 (Lars Duening) (3.3.75)
- (configure) When testing for mySQL, the driver automatically checks
in /usr/local/include as well (some systems don't have it the
default include path).
- (configure) Added a check for 'minimal optimization' options.
- (configure) When compiling on Windows, link in a couple of more
libraries. This might not be fully correct yet.
- (make_func.y) Removed a couple of warnings under gcc 3.0 (thanks,
Largo!).
- (comm.c) On a regular shutdown, stop the erq demon explicitely.
- (main.c) When compiling for MSDOS_FS, the erq pathname wasn't built
correctly (reported by Coogan).
- (sprintf.c) Simul-efun closures printed with %O are marked as such.
- (closure.c) Comparison of operator, efun, and simul-efun closures
was instable (reported by Nathan).
13-Jul-2001 (Lars Duening) (3.3.74)
- (comm.c, parse.c, parse_old.c) Removed a couple of
undefined behaviours, detected by gcc 3.0 (thanks, Largo!)
- (sprintf.c) Format modifier '$' instructs (s)printf() to not remove
padding white space before a lineend.
- (efuns) New efuns gmtime() and localtime() to return the time broken
up into its constituents (suggested by Markus Peter).
- (lex.c) Escaped character constants are now only parsed up to a
maximum length. If no valid digits are found, the whole item
is simply treated as escaped character (thanks, Fiona!).
05-Jul-2001 (Lars Duening) (3.3.73)
- (prolang.y) It is now possible again to redefine a non-static inherited
variable with a static one (or vice versa), but it also generates
a warning.
- (doc/concepts/intermud*) Intermud-2 documentation added (thanks, Fiona!)
03-Jul-2001 (Lars Duening) (3.3.72)
- (prolang.y) How embarrassing! The code for !INITIALIZATION_BY_INIT
had a bad syntax error - and I didn't notice it (thanks, Bardioc!)
01-Jul-2001 (Lars Duening) (3.3.71)
- (configure) 'with_wizlist_file=no' didn't work from settings files
(reported by Freaky).
- (lex.c) '//' comments didn't like to be terminated by the end of
file (reported by Matthew).
30-Jun-2001 (Lars Duening) (3.3.70)
- (hosts/os2) Updated the OS/2 port (provided by Bart).
30-Jun-2001 (Lars Duening) (3.3.69)
- (prolang.y) Relaxed type checking somewhat so that a non-mixed
function argument can be redefined to mixed, and vice versa
(suggested by Gnomi)
- (lex.c) Escaped character constants in inline closures weren't
recognized (reported by Freaky and Gnomi)
- (doc/LPC/comments) New.
- (configure.in) When using mySQL, also check for libnsl.
- (configure.in) The mySQL path is now used for both include
and library searches.
29-Jun-2001 (Lars Duening) (3.3.68)
- (prolang.y) Accidentally it was no longer possible to redefine
privately inherited variables (reported by Gnomi).
- (actions.c, simulate.c) New hook H_SEND_NOTIFY_FAIL to deliver
the notify fail message. It is meant for those muds who want
control over the command flow without having to implement everything
themselves via the H_COMMAND hook. This hook is still experimental
and may change in details (suggested by Gnomi).
- (prolang.y) It is now possible to define a default visibility
for functions and variables (see doc/LPC/modifiers) (suggested
by Freaky).
29-Jun-2001 (Lars Duening) (3.3.67)
- (main.c) Commandline arguments can now be read from a textfile, using
new commandline option '--args'. These argument files can be nested.
(suggested by Elric)
28-Jun-2001 (Lars Duening) (3.3.66)
- (configure) The evaluation of the '--with-wizlist-file' configuration
option was less than flawless.
- (main.c) Instead of scanning the arguments twice, all encountered
-f options are stored in a temporary list and evaluated when
it's time (f-010603-1).
- (main.c) Laid the groundwork for nested sources for the command
arguments.
27-Jun-2001 (Lars Duening) (3.3.65)
- (simulate.c) When parsing callback arguments, the pattern 'function,
object, extra' was parsed such that 'object' became part of the
'extra' arguments (reported by Marthin).
- (lex.c) It is now possible to use symbols in inline closures, ie.
"(: 'a :)" (reported by Menaures).
- (main.c, lex.c, wiz_list, configure) The name of the WIZLIST file
can now be configured at compile time and with commandline option
'--wizlist-file'. The LPC macro __WIZLIST__ expands to the selected
name. The WIZLIST file can also be disabled completely
('--no-wizlist-file'), in which case __WIZLIST__ is not defined
at all (based on a patch from Elric).
- (call_out.c) Corrected a fatal refcount bug in the garbage collection
of call_outs with destructed command givers (reported by Gnomi).
22-Jun-2001 (Lars Duening)
- (sprintf.c) Column-formatting a string with one newline
printed one newline too few if the formatstring didn't end
immediately (reported by Gnomi).
21-Jun-2001 (Lars Duening)
- (make_func.y, lex.c) Identifier names can use the extended alpha
characters from the ISO 8859-1 alphabet (suggested by Elric).
17-Jun-2001 (Lars Duening) (3.3.64)
- (backend.c) cleanup_stuff() also executes a clear_state() to
avoid dangling object references (reported by Gnomi).
- (pkg-mysql.c) Added efun db_error() to return the most recent
error string (thanks to Casey and Dafire).
- (efuns.c) If the driver is compiled with DYNAMIC_COSTS, the cost
of efun clones() is proportional to the number of objects
in the game.
13-Jun-2001 (Lars Duening) (3.3.63)
- (prolang.y) Global variables can no longer be redefined (reported
by Coogan).
- (doc/efun/operators) Clarified the behaviour of (<type>) casts.
- (simulate.c, interpret.c) Normal runtime errors (and their traceback)
are no longer reported on stdout at all (reported by Tomi).
- (etc/startmud.pl) Added a simple start/keep-alive script - feel
free to improve on it (thanks, Krystal-Anne!)
11-Jun-2001 (Lars Duening) (3.3.62)
- (interpret) Nifty little crasher: if the object holding the closure
currently execute is destructed, the interpreter happily tried
to free the closure after execution without noticing
that it already has been freed (as part of the object destruction
process) (reported by Freaky).
09-Jun-2001 (Lars Duening) (3.3.61)
- (mstrings.c) strstr("text", "") erroneously returned 'not found'
instead of 0 (reported by Bardioc).
- (mapping) Corrected the SIZEOF_ macros (most of them gave a too
big number, but SIZEOF_MC undercalculated for wide mappings);
and corrected one calculation in the total statistic (instigated
by Bardioc).
- (configure, lex.c) 'nosave' is now a permanent feature in LPC; the
configuration option 'use-nosave' no longer exists (suggested
by Coogan).
- (main.c) Improved the formatting of the language options in the
'--options' output.
- (pkg-mysql.c) In the call to mysql_real_connect(), the arguments
for database and user/password were given in the wrong order
(thanks, Malcom!).
07-Jun-2001 (Lars Duening)
- (comm.c) The driver forgot that it is in noecho/charmode mode after
the second consecutive input_to call, sending out unnecessary
telnet negotiations.
- (interpret.c) When an object is destructed, all references to it
are removed from the stack - including references through
closures. Before, only direct T_OBJECT references were removed
(reported by Gnomi).
04-Jun-2001 (Lars Duening) (3.3.60)
- (prolang.y) The type on function return is too strict (or the
type tracking in general too lacking) unfortunately,
so I took it out again.
03-Jun-2001 (Lars Duening) (3.3.59)
- (prolang.y) A cast of a type to itself is now a no-op as it should
be (reported by Gnomi).
- (interpret.c, prolang.y) Integers and float can now be compared
against each other (suggested by Gnomi).
- (gcollect.c) The GC forgot to trace the program->blueprint pointer
which was introduced 3.3.40 (reported by Coogan).
02-Jun-2001 (Lars Duening)
- (lex.c, mstrings) The lexer can now create literal strings with
embedded \0 characters.
- (backend.c) The check_alarm() function also restores the alarm
signal handler.
- (prolang.y) It is now possible to cast to '(mixed)'.
- (prolang.y) Improved the type tracking of '?:': it now accepts
operands of different types and evaluates to 'mixed' in that
case (reported by Dennis VanHoey)
- (prolang.y) Improved the type checking at function return under
strict_types.
25-May-2001 (Lars Duening)
- (configure) Comments may now appear at the end of the lines in
a settings file (thanks, Bertram!).
24-May-2001 (Lars Duening) (3.3.58)
- (efuns) Efun terminal_colour() can now use closures to translate
colour keys (suggested by Elric).
- (prolang.y, pkg-alists) When using alists, the compiler needs the
order_alists() function for constant expressions.
- (object.c) Efun say() freed an array once too often (reported by
Nostradamus).
- (backend.c) Removing destructed objects in the process-objects
loop clobbered the list of programs to replace (reported by
Gnomi).
22-May-2001 (Lars Duening)
- (efuns.c) Efun regreplace() can now take a closure to produce
a replacement string (suggested by Fiona) (f-010516-2).
16-May-2001 (Lars Duening) (3.3.57)
- (mapping.c) Missing parentheses around a ?: construct could crash
the driver (thanks, Bardioc).
- (prolang.y) The non-__INIT code referenced F_ORDER_ALIST even when
alists are disabled (thanks, Bardioc).
- (backend.c) The call to clean_up() erroreously counted the internal
blueprint-program reference to the reference count passed to the
clean_up() apply. Additionally, before the call all pending
destructed objects are removed (suggested by Elric).
- (rxcache.c) The regexp cache forgot to compare the excompat flag,
occasionally selecting the wrong regexp (thanks, Fiona).
15-May-2001 (Lars Duening) (3.3.56)
- (sscanf) Clarified the documentation regarding the matching of
'%s' (reported by Pulami and Gnomi)
- (closure.c) Compiling a simul_efun with extended varargs in a
lambda closure created faulty bytecode (reported by Gnomi).
13-May-2001 (Lars Duening) (3.3.55)
- (prolang.y) Undid the casting change, as it broke the idiom
's = (string)foo->bar();' where bar() may signal a failure
by returning integer 0. It's the old 0/nil dichotomy again.
- (efuns.c) Efun sscanf(): the format '%s%d' failed to parse 'ab1cd'
correctly (reported by Pulami).
09-May-2001 (Lars Duening) (3.3.54)
- (prolang.y) Casting an unknown or mixed type now always inserts
a proper conversion (reported by Tomi).
- (heartbeat.c) The result for DID_ST_HBEAT_AVG_PROC was computed
as int instead of float (reported by Freaky).
- (mud/morgengrauen) Added basic support for the MorgenGrauen 3.2.6
mudlib.
08-May-2001 (Lars Duening)
- (prolang.y) The expression 'a & b' failed to track the types if one
of the operands was of TYPE_ANY (reported by Gnomi).
06-May-2001 (Lars Duening)
- (interpret.c) Added a protection against simple reference loops
as created by 'b = 0 || &a; b = 0 || &a;' (reported by Gnomi).
29-Apr-2001 (Lars Duening) (3.3.53)
- (mapping.c) m_values() failed to properly check the mapping width,
especially on empty mappings.
- (array.c) Looking up a key in an array failed on some arrays (reported
by Freaky).
- (prolang.y) Nested definitions of inline closure no longer generates
warnings about the arguments shadowing previous declarations
(reported by Freaky).
28-Apr-2001 (Lars Duening) (3.3.52)
- (several files) Removed the support for Atari and OS/2, restricted
the Amiga support to gcc/ixemul.
- (pkg-alists.c) Removed compiler warnings.
27-Apr-2001 (Lars Duening) (3.3.51)
- (sprintf.c) Duh. A typo caused '%^' to eat the next character
from the format string (reported by Robert).
- (sprintf.c) A leading '0' used to pad the whole field with 0s.
Now, only leading 0s are printed and this setting and the
explicite pad string are independent of each other (suggested
by Fiona).
- (call_out.c) Removing call_outs, or call_outs going stale, messed
up the 'number of callouts' statistics (provided by Gnomi).
- (autoconf) Oops, the USE_ALISTS option lacked a crucial substitution.
- (mapping.c) Freeing mappings clobbered memory.
25-Apr-2001 (Lars Duening) (3.3.49 and 3.3.50)
- (efuns.c, array, parse.c, parse_old.c, interpret.c)
Removed the last uses of old_explode_string().
- (array, pkg-alists, object.c, swap.c, configuration) Alists are
now an optional package. By default alists are not supported,
however, I edited all settings/ files to include support.
(suggested by Freaky)
- (prolang.y) Pre-increment or -decrement failed to terminate
the parser reduction, causing an internal fatal error when the
result was used somewhere (reported by Dafire).
24-Apr-2001 (Lars Duening) (3.3.48)
- (efuns.c) Efun sgn() used on negative integers still returned +1 -
a simple typo (thanks, Fiona!).
- (mapping,dump_stat.c, func_spec, interpret.c, swap.c) I re-implemented
the mappings. Originally I tried to devise a better way of
storing mappings in memory, but in the end I ended with the scheme
Amylaar used already. Just that now both layout and code are
a bit simpler and easier to maintain. Oh, and the obsolete
efun copy_mapping() is gone, too.
22-Apr-2001 (Lars Duening) (3.3.47)
- (array.c) When using a multi-dimensional allocate(), specifying
0-sized dimensions could crash the driver (reported by Menaures).
- (Makefile.in) When doing 'make install', the driver is now installed
as 'driver', not 'parse' (reported by Eivind).
- (docs) Some corrections, provided by Fiona.
- (closure.c) The generation of sparse lookup ranges failed to properly
generate default-jumps for the values between two consecutive
ranges (e.g. 'case -2..-1:, case 1..2:' was smudged into 'case -2..1:
case 0..2:') (reported by Menaures).
20-Apr-2001 (Lars Duening) (3.3.46)
- (mapping.c) Removed a couple of fatal bugs in the key deletion
(reported by Freaky).
19-Apr-2001 (Lars Duening) (3.3.45)
- (configure, main.c, simulate, call_out.c) Runtime for the total
number of callouts, settable with commandline option
'--max-callouts'.
18-Apr-2001 (Lars Duening) (3.3.44)
- (interpret.c) Corrected a crasher when freeing protected char lvalues.
- (func_spec, prolang.y, interpret.c) foreach() can now iterate over
references to arrays/mappings/strings, allowing the loop to change
them (f-010406-1).
- (prolang.y, interpret.c) foreach() can now iterate over integers
and integer ranges (f-000221).
- (object.c) Fixed another compilation problem for COMPAT mode
(reported by Ralph).
17-Apr-2001 (Lars Duening) (3.3.43)
- (prolang.y) Redefining an inherited private heart_beat() didn't work:
the new heart_beat() wasn't called (reported by Gnomi).
- (rxcache.c) The status functions were far too slow, because they
counted the number of entries on each call (reported by Sissi).
- (prolang.y) Function calls can distinguish between variables and
functions of the same name (suggested by Gnomi).
- (prolang.y) Warnings while loading the master caused the load to
fail.
16-Apr-2001 (Lars Duening) (3.3.42)
- (object.c) Ooops, didn't compile in COMPAT mode (reported by Ralph).
13-Apr-2001 (Lars Duening) (3.3.41)
- (simulate.c) Made the 'illegal object to load' error message
more informative (suggested by Freaky).
- (mapping.c) Modified to mapping code to be able to use closures
as proper keys.
12-Apr-2001 (Lars Duening)
- (pkg-mysql.c) Forgot to include mstrings.h here (reported by
Gawain and Bardioc)
- (sprintf.c) The formatter "%^" will print "%^" for compatibility
with terminal_colour().
- (closure.c, array.c) Introduced a total order on closure svalues
which allows their use in alists and array operations like
intersection. The same will have to be done later for their use in
mappings (reported by Gnomi).
11-Apr-2001 (Lars Duening) (3.3.40)
- (prolang.y, interpret.c, func_spec) Wildcarded calls to inherited
functions confused arguments with results and messed up the stack.
Introduced a dedicated bytecode for this situation.
- (prolang.y) Additions of floats to constant 0 yielded TYPE_ANY
instead of TYPE_FLOAT.
- (interpret.c) Arguments passed to runtime_error() were wrong
if the error happened in a master apply (reported by Gnomi).
10-Apr-2001 (Lars Duening)
- (exec.h, prolang.y, simulate.c) The program structure received
a pointer pointing to the blueprint object. Main purpose is to
allow the cheap deep update of the master object, but other uses will
probably show up as well.
- (simulate.c) Added function deep_destruct() to destruct an
object and the blueprints of all inherited programs.
- (backend.c, interpret.c) The signal SIGUSR1 now destructs the
master object and all its inherits, to allow a clean reload.
07-Apr-2001 (Lars Duening) (3.3.39)
- (smalloc.c) The multiple-of allocation was not quite correct.
- (Makefile.in) The pkg-mysql file was missing from the build
rules (reported by Dafire).
06-Apr-2001 (Lars Duening) (3.3.38)
- (md5.c) Removed a compiler warning.
- (closure.c, interpret.c, prolang.y) Bugfixes in the '...' code
generation.
- (interpret.c) Indexing beyond the bounds of a rvalue string
returns -1 as 'character' value.
- (smalloc.c) On Darwin, we get the memory from the system only
in multiples of 64 Bytes, which caused the creation of too-small
large blocks. Fixed that.
05-Apr-2001 (Lars Duening) (3.3.37)
- (object.c) Removed an occasional crasher from restore_object()
(reported by Freaky).
- (func_spec, prolang.y, interpret.c) Reworked and completed the
support for the '...' argument operator (f-990417-9).
- (object.c) The error messages for save_object() and restore_object()
also print the filename in question.
04-Apr-2001 (Lars Duening)
- (func_spec, prolang.y, interpret.c) Added experimental support
for the '...' argument operator (flatten argument). It works
for lfuns and probably simul_efuns and doesn't break existing
code, but I have to rework it to handle efuns efficiently.
One of the problems is the one pass nature of the LPC compiler,
which allows to nest function calls into function call arguments.
04-Apr-2001 (Lars Duening) (3.3.36)
- (Makefiles) Corrected.
- (efuns, md5) New efun md5_encrypt() (thanks, Gawain!)
- (lex.c) An attempt to '(: ;} fun() {... :)' is now detected and
rejected (reported by Daniel Fischer).
03-Apr-2001 (Lars Duening) (3.3.35)
- (lex) Corrected a bug in yesterday's change.
- (doc/) Cleaned up the files a bit.
- (erq, xerq) Fixed (hopefully) a type mismatch under Darwin.
- (make_func, parser) Wrapped the parsers into a file defining 'lint'
to avoid spurious warnings, and under Darwin to enable to compile
them in the first place. As a result, make_func is now called
'mkfunc', and the lpc parser is 'parser.[co]'.
02-Apr-2001 (Lars Duening) (3.3.34)
- (lex) When generating names for inline closures, the compiler
makes sure that the name hasn't been used yet (reported by Dan).
30-Mar-2001 (Lars Duening)
- (lex.c) The include path and filenames returned by the master the
and H_INCLUDE_DIRS closure can now start with leading slashes
(suggested by DaFire).
- (xerq) The incoming data buffer is cleared before each new command,
in order to detect errors more easily (suggested by Gawain).
- (comm.c) When using charmode against non-charmode clients (TinyFugue),
the line end wasn't handled properly. The solution is to receive
the data in charmode, but to pass it on to the user as if in
linemode.
- (comm.c) Newline sequences received in charmode are passed to the
mudlib as-is. Older drivers used to pass empty strings in their
place, which made handling clients which refused to go into charmode
difficult.
27-Mar-2001 (Lars Duening)
- (interpret.c) All <op>= assignment operators can now operate on
indexed strings on the left hand side.
22-Mar-2001 (Lars Duening)
- (closure.c) Default arguments were not properly stored by
prefix/bytecode (reported by Zwirch).
- (efuns.c) The optional argument to get_type_info() was no longer
optional (reported by Zwirch).
21-Mar-2001 (Lars Duening) (3.3.33)
- (stralloc-away) Deleted these files.
- (mstrings.c) Repeating a string 0 times left clobbered memory.
20-Mar-2001 (Lars Duening) (3.3.32)
- (erq, xerq/execute.c) Quoted arguments are recognized and not split into
words (provided by Christian W., thanks!)
- (backend.c) The no-var-swapping time before a reset() is limited to
5 minutes max, otherwise a lot of muds will never swap variables.
- (object.c) A correction to the correction to functionlist() (thanks,
Fiona!).
- (func_spec, array.c) Efun allocate() now accepts an initialisation
value (f-981229-09a).
- (configure.in) When using mySQL, the script also checks for and links
in the libz (reported by Bardioc).
19-Mar-2001 (Lars Duening)
- (func_spec, closure.c) The definition of bind_lambda() didn't work.
- (mapping.c) Keyvalues for strings were still computed incorrectly.
16-Mar-2001 (Lars Duening) (3.3.31)
- (pkg-mysql.c) Dafire provided to new mySQL efuns: db_insert_id()
and db_coldefs() - thanks!.
- (object.c) The list control for functionlist() was documented
incorrectly, and also functioned incorrectly (thanks, Fiona!).
15-Mar-2001 (Lars Duening) (3.3.30)
- (settings/unitopia) Updated (thanks, Freaky!).
- (comm.c) The pathlength safety check in the start-erq-demon routine
was too cautious (thanks, Freaky).
- (mudlib/dhrystone.c) Added a missing assignment.
- (mstrings.c) String comparisons of equal length failed to detect
equality (reported by Nostradamus).
- (xerq/Makefile.in) Accidentally left the XDEBUG option enabled.
- (make_func.y) The LPC runtime argument types for all but the first
efun arguments were corrupt. Also made this table a wee bit more
compact.
- (comm.c) A prompt closure bound to a destructed object is detected
and restored to the default prompt. An error is still thrown, to
give the mudlib hackers something to do.
- (pkg-mysql.c) The version check did not really work (thanks, Dafire).
14-Mar-2001 (Lars Duening) (3.3.29)
- (interpret.c) collect_trace() freed a filename information which
was still needed.
- (prolang.y, closure.c) Sorting and searching of aligned functions
must be done by comparing the name pointers downcasted to (char*).
If not, the differences reported don't allow for reliable searching.
- (efuns.c) regreplace() didn't work well with empty strings.
- (files.c) Reading an invalid file caused a fatal() error.
- (rxcache.c) The condition to check for a match was reversed.
- (main.c, comm.c) The command option '--erq' can now be used to
specify the full pathname of the erq executable (suggested
by Freaky).
- (comm.c) Before printing a prompt via a closure, the current object
is set to the command giver. This avoids a crash under (admittedly
rare) circumstances of closure destruction.
13-Mar-2001 (Lars Duening) (3.3.28)
- (backend.c) When calling the master apply slow_shut_down(), it is
made sure that previous_object(), this_player(), and
this_interactive() are all 0 (reported by Freaky).
- (comm.c, ed.c, interpret.c, simulate.c) Removed spurious checks
for out-of-memory condition. While the intention is noble, it hasn't
been implemented consequently enough to be of any use.
- (mstrings.c) cvt_progname() got the meaning of compat_mode reversed.
- (object.c) restore_object() tried to restore from the wrong filename.
- (comm.c) If a CRLF as expansion of a NL character was to be inserted,
but only one character was left in the buffer, the code errorneously
detected a 'message shorter than minimum, needs not be send'
condition, thus swallowing all following characters after the NL.
- (main.c) The lexer, and with it the permanent defines, was initialized
before the master name had been determined.
- (interpret.c) Reverse-indexing before the start of a string is allowed
and returns 0.
- (interpret.c) Argl. Letting the ==/!= comparison for floats fall through
to the all new and improved closure comparison was not a good idea
(reported by Gnomi and Freaky).
12-Mar-2001 (Lars Duening)
- (pkg-mysql.c) db_connect() optionally takes a username and a password
(thanks, Andre!)
- (mapping.c) Keyvalues for strings were computed incorrectly.
- (efuns.c) The result for terminal_colour() and to_string(array)
was alloced one too long.
09-Mar-2001 (Lars Duening) (3.3.27)
- (array.c, rxcache.c, interpret.c, mstrings, simulate.c, mud/lp-245)
Bugfixes.
- (configure) Another define for 'void' signal return types - this one
can be tested directly, as a comparison of the values of RETSIGTYPE
is not portable.
The driver is now able to run lp-245, and boot into Evermore-native.
08-Mar-2001 (Lars Duening)
- (mstrings.c) Removed a couple of bugs.
07-Mar-2001 (Lars Duening) (3.3.26)
- (gcollect.c, string_spec) Corrected compilation errors.
- (interpret.c) Freeing a T_FLOAT svalue is allowed, too. And not
defining TRACE_CODE accidentally removed a handful of
efuns.
- (comm.c) Writing a string to stdout via add_message() didn't work.
06-Mar-2001 (Lars Duening) (3.3.25)
- (mstrings.c, array.c) xalloc_pass() was called with too many arguments,
clobbering the size of the allocate memory block.
- (gcollect.c) The global master name as tabled name was freed by
accident.
- (comm.c) add_message() didn't recognize the flush message.
- (interpret.c) Freeing an T_INVALID svalue is allowed.
Implemented changes up to 3.2.9-dev.263:
- (smalloc.c) Corrected a statistics error (reported by Freaky).
- (simulate, interpret, efuns.c) Added the last error trace as
possible return from debug_info(DINFO_TRACE) (suggested by Gnomi).
- (interpret.c) Removed a VM stack leak in ++/-- on floats (reported
by Dafire).
- (object.c) The previous object for object resets is this_object()
(reported by Gnomi).
- (Makefiles) Added 'lint' to the compiler defines to ensure a smooth
compilation of prolang.y.
- (backend.c) Simplified the error message output in write_file().
- (simulate.c) The master apply runtime_error() receives an extra
argument describing if the error is a normal error, or occured
during a heartbeat (suggested by Freaky).
- (gcollect.c) Added a dump function for closure literals.
- (lex.c, gcollect.c) Cosmetics.
- (smalloc.c, main.c) xfree() now accepts NULL pointers. Allocation of
MIN_(SMALL_)MALLOCED blocks actually check if the memory is
allocated (reported by Freaky).
- (main.c, backend.c, interpret.c) Swapping is no longer an optional
feature, though it still can be disabled by specifying swapping
times of 0.
- (configure.in, main.c, xalloc) New commandline options '--min-malloced'
and '--min-small-malloced' to complement the configuration options
(suggested by Freaky).
- (hosts/win32) Updated the various files with those provided by
Coogan (thanks!)
- (smalloc) Renamed the constant MASK to M_MASK, as MASK seems to clash
with one of Darwin's symbols.
- (func_spec, efuns) The efuns debug_info() and object_info() can now
return single values instead of whole arrays.
- (backend, comm.c) Added a check method which restarts the alarm
after some time of activity. This is required at least for
Cygwin on Windows, where the alarm often gets lost (thanks, Holger!).
- (interpret.c) The master apply valid_trace() now receives as second
argument the argument passed to the efun (suggested by Coogan).
- (lex.c, prolang) Inline closure 'inherit' the visibility modifiers
of their defining function (suggested by Coogan).
- (smalloc.c) Corrected an accounting error in consolidate_freelists().
- (autoconf/configure.in) Some more small fixes.
- (prolang.y) Recognize an inherited heart_beat() only if it is visible
(adopted from Morgengrauen).
- (efuns.c) debug_info(DINFO_DATA, DID_STATUS) now returns the number
of executed heartbeats as well as the total number of heartbeats.
- (settings/morgengrauen) New configuration file.
- (autoconf/configure.in) Corrected some replacement directives.
- (func_spec) Removed two duplicate efun definitions which caused
Cygwin compiles to hang.
- (make_func.y, lex.c) Added diagnostics to detect duplicate efun
and string definitions.
- (autoconf/configure.in) The option --enable-use-mysql now also
accepts a directory path under which the libmysqlclient can be
found (f-000918).
- (main.c) Added code to unblock SIGALRM on program start - on systems
it is blocked randomly for no obvious reason (thanks, Fini!)
(maybe fixes b-000308)
- (efuns, func_spec) New efun sgn() to retrieve the sign of a numeric
argument (suggested by Croft).
- (lots of files) New configuration option 'use-deprecated' allows
to disable obsolete and deprecated efuns. If enabled, the macro
__DEPRECATED__ is defined (suggested by Coogan).
- (lots of files) The UDP port is now a standard feature. The
option has been renamed from 'catch_udp_port' to just 'udp_port'.
- (lots of files) The UDP efuns have been renamed from send_imp()
and query_imp_port() to send_udp() and query_udp_port(); as were
the associated privilege violation string and the master apply.
11-Feb-2001 (Lars Duening) (3.2.24)
Included changes up to 3.2.9-dev.255:
- (smalloc.c) Removed a compilation error (reported by Coogan).
- (strfuns.c) When (re)allocating the strbuf buffer, the length was
accidentally casted down to unsigned short, causing the program
to write outside the allocated memory (reported by Sebastian).
- (smalloc.c) Using the time_stamp() from within the allocation routines
was really stupid.
- (smalloc.c) The large block allocator had an off-by-one error which
left free large blocks of 'small' size behind. These blocks could
never be allocated, just merged again.
- (smalloc.c) The routine to split largish free small blocks was faulty,
causing coredumps.
- (parse_old.c) Expanded the list of hard coded prepositions.
- (lex.c) Added new standard predefine __LDMUD__, expanding to an empty
string.
- (settings/heaven7, mud/heaven7/) Added basic support for Heaven7: you can
boot the mud and log in. There are probably still errors in the
areas.
- (func_spec) The result of set_prompt() can be a string or a closure,
yet it was declared to return only string (reported by Gnomi).
- (prolang.y) The type tracking for multiplication returned an 'int'
result even for 'mixed' operands (reported by Gnomi).
- (interpret.c) The relations '==' and '!=' can now compare lfun-
and variable closures (suggested by Gnomi).
- (func_spec, efuns) New efuns min() and max().
- (configuration, smalloc.c) Added a new config parameter
MIN_SMALL_MALLOCED which defines the size of the first small chunk
allocated by the system.
- (xerq) With ERQ_FORK started subprocesses are now as well handled
with a child_t structure. While not exactly necessary, it allows
for useful diagnostics in the sig_child() handler (reported by
Freaky).
- (dumpstat, efuns.c) The internal data measuring routines now return
both the total data size, as well as the data size scaled down
according to the extend of data sharing. The results are also
returned by object_info(OI_MEMORY) (suggested by Freaky).
07-Feb-2001 (Lars Duening)
- (Many files) Bugfixes. The driver is now able to boot the test_master.c
and call simple functions, but dies in a garbage_collection or when
printing the 'status' on login. This however could be caused by
the pending bug in smalloc and strbuf (fixed in 3.2.9-dev.255).
06-Feb-2001 (Lars Duening)
- (sprintf, swap, wiz_list, xalloc) Adapted to new string implementation.
This completes the basic string adaption - it compiles, it links, it
can display its options, it probably crashes and burns when you try
to boot a mud with it.
05-Feb-2001 (Lars Duening)
- (simulate, simul_efun, strfuns) Adapted to new string implementation.
02-Feb-2001 (Lars Duening)
- (object, otable, parse, parse_old, rxcache) Adapted to new string
implementation.
31-Jan-2001 (Lars Duening)
- (prolang, main, pkg-mysql, mapping) Adapted to the new string
implementation.
- (array, mstrings, xalloc.h) Removed compilation errors.
26-Jan-2001 (Lars Duening) (3.3.23)
Included changes up to 3.2.9-dev.254:
- (smalloc.c) Introduced a free list for 'oversized' small blocks which
is used much like the unused space in a small chunk. This list
allows the consolidation function to keep large free blocks
together even if they exceed the legal maximum size for small
blocks.
- (smalloc, gcollect.c) New function consolidate_freelists() to
rebuild the small block free lists, merging adjacent free small
blocks where possible. Additionally, when a small chunk is exhausted
the small block allocator first tries to split one of the larger
free blocks before getting a new small chunk.
- (xerq/execute.c) Corrected some small bugs (thanks, Freaky!)
- (port.c) The time_stamp routines recompute the string result only
if the time has changed since the last call.
- (efuns.c, smalloc.c) smalloc now keeps a statistic about the number
and size of permanent and clib allocations; and debug_info()
returns this statistics as part of (DINFO_DATA, DID_MEMORY).
- (smalloc.c) Defining the macro DEBUG_SMALLOC_ALLOCS causes smalloc
to log all new allocations which can't be satisfied directly
from the free lists. The output is written to the same stream
as the GC log (default is stderr).
23-Jan-2001 (Lars Duening)
- (mstrings) Made the reference behaviour of mstring_dup() and
mstring_resize() more intuitive.
- (lex) Adapted to new string implementation.
22-Jan-2001 (Lars Duening)
- (interpret.c, mstrings, string_spec) Completed adaption of interpret.c
to new string implementation.
19-Jan-2001 (Lars Duening) (3.3.22)
- (interpret.c, mstrings) Continued adaptation.
Included changes up to 3.2.9-dev.251:
- (main.c) Change to the default MUD_LIB directory early, so that the
debug.log file is opened in the right place (reported by Elric).
- (xerq) The parent now synchronizes with the child by sending a specific
byte of data.
- (pkg-mysql.c) Markus Peter provided a patch for backwards compatibility
with mySQL before 3.22.24.
- (main, comm.c) The name of the erq executable can now be given on the
commandline with the option '--erq <filename>' (suggested by Freaky).
- (comm.c) In efun exec(), if this_interactive() points to one of the
the involved objects, it is switched over as well, like this_player()
already is (reported by Elric).
- (xerq) Freaky found and corrected a couple race conditions in the
clean-up loops of socket and children.
- (backend.c) Efun debug_message() now allows to preprend the message
with a timestamp for the current date and time, controlled by
a new bitflag (suggested by Freaky).
- (xerq) Added additional diagnostic output, activated with compiler
option XDEBUG. Also, removed two uninitialized variables (the stdout/
stderr sockets in the child_t structure) in the handling of child
processes, and added measures against buffer overflows.
- (erq.c, xerq/socket.c) When closing the connection to a child
process, the erq makes sure to read all still remaining data
from the connection (reported by Freaky).
21-Dec-2000 (Lars Duening) (3.3.21)
Included changes up to 3.2.9-dev.250:
- (comm.c, interpret.c) More small corrections to the new telnet
error reporting.
- (func_spec, backend.c) Extended the efun debug_message() to take
a parameter telling where to log the message (suggested by Freaky).
- (comm.c) If the driver received only a NL in charmode, the first
following character was ignored.
- (comm.c) Found and corrected a problem concerning the use
of CHARMODE with Windows' telnet: the charmode negotiation were
considere a failure too early, and moreover the CHARMODE_REQ flag was
reset without adjusting the input buffer variables. Unfortunately
this re-opens b-000818. (b-001214)
- (comm.c) Clients sending CRLF in Charmode instead of just CR
are now handled properly: the LF is ignored like the NUL in CR NUL
already is. This also re-fixes b-000818.
- (comm.c) When receiving DONT ECHO or WONT SGA, the check for if
the option has already been granted was wrong.
- (comm.c) After a charmode input_to() has been received, the driver
did not properly reset the text pointers, causing !-escaped
commands to go unrecognized.
19-Dec-2000 (Lars Duening) (3.3.20)
- (interpret.c) Continued adaptation.
Included the changes up to 3.2.9-dev.249:
- (mudlib/floattest.c) Unfortunately this code was a derivate of
a copyrighted program from Numerical Recipes, and therefore can't be
distributed legally.
- (lex.c) On solaris, strtod() does not clear errno after a successful
conversion, causion spurious warnings (reported by Coogan).
- (main.c) The driver version is now also printed in the .debug.log
file on startup.
- (comm.c) A bug in the comm_fatal() routine caused the driver to
abort on the second call to it. Oops. (reported by Gnomi and
Freaky)
15-Dec-2000 (Lars Duening) (3.3.19)
- (interpret.c) Continued adaptation.
Included the changes up to 3.2.9-dev.248:
- (comm, simulate.c) When the telnet machine for a player gets into
an inconsistent state, the driver no longer aborts. Instead, the
player's interactive structure is dumped to stderr, and then
removed the hard way.
- (regexp.c) Added the metacharacter '+' (match at least once'
to the regexp code (provided by Terry Penn, thanks!).
- (mudlib/floattest) This LPC program computes the floating point
characteristics; it can be called from the test_master (provided
by Croft, thanks!)
- (lex.c) Octal numbers are now prefixed by '0o' - it's cleaner
and avoids compatibility problems with existing code.
- (interpret.c) Omitting a check_map_for_destr() in a mapping addition
caused data in a wiz_info mapping to mysteriously disappear (thanks,
Coogan) (b-001204).
- (prolang.y) The result type for '++map[mixed]' was computed
incorrectly (reported by Freaky).
- (comm.c) If an error occurs on accept(), the driver no longer abort()s
but prints a better error message.
06-Dec-2000 (Lars Duening) (3.3.18)
Included the changes up to 3.2.9-dev.244:
- (lots of files) Closures bound to destructed objects are now treated
like destructed objects and zeroed out where possible.
- (wiz_list) Destructed objects and closures is now removed from the
'extra' wizinfo in regular intervals. Note that this doesn't
extend to subarrays and -mappings held by the 'extra' info.
- (autoconf/configure.in, configure) If MySQL or IPv6 are not requested,
the configure script won't check for the libraries; consequently
they won't linked in unless needed (suggested by Coogan).
- (interpret.c, prolang.y) The operators '++' and '--' can now be
used on floats, too (suggested by Croft).
- (interpret.c) sqrt(0.0) caused a 'bad argument' error - corrected
that (thanks, Andre!).
- (interpret, efuns.c) debug_info(DINFO_TRACE) returns the current
call stack as either string or array. (f-000716)
- (interpret.c) The efuns sin(), cos(), tan(), atan(), atan2(),
log(), exp(), sqrt() and pow(), when given an integer argument,
returned a float result typed as integer. (reported by Slava)
- (lex.c) Oops, a last minute change to remove a warning broke the
recognition of escaped characters in strings (thanks, Slava!).
- (interpret.c) Efun pow() did not properly check its arguments.
27-Nov-2000 (Lars Duening) (3.3.17)
Included the changes up to 3.2.9-dev.240:
- (lex.c) Numbers can be specified in binary using the '0b' prefix.
- (lex.c) Moved the parsing of escaped character sequences into a
separate function, and implemented the specification of characters
through their numeric code (expressed in decimal, octal, sedecimal
and binary). (f-990203-04)
- (closure.c) Implemented catch-nolog as '({#'catch, <body>, 'nolog })'.
- (prolang) Folded catch() and catch_nolog() back into one catch(),
distinguished by the keyword 'nolog'.
- (func_spec, efuns.c) The efuns sin(), cos(), tan(), atan(), atan2(),
log(), exp(), sqrt() and pow() now accept integers as arguments, too.
The results remain float. (suggested by Croft).
- (interpret.c, mapping.c) When testing for a 'mapping too large' condition
on mapping addition or element assignment, it is made sure that all
invalid keys have been removed. (reported by Fiona)
- (func_spec, lex.c, interpret.c, simulate, prolang.y) New language
construct catch_nolog() as alternative to catch(): the new statement
doesn't log the error in the driver logfiles (thanks, Michael!)
(p-990901).
- (lots of files) The mode of the driver (plain or compat) can now be
selected with the commandline options '--no-compat' resp. '--compat'.
The default is still selected during configuration. (f-981229-00)
- (mudlib/sys, doc/) Small corrections (thanks, Coogan!).
- (mudlib/telnet_neg.txt) Added Slava's example on telnet negotiation,
which includes a means of measuring lag using TMs (thanks!).
15-Nov-2000 (Lars Duening) (3.3.16)
Included the changes up to 3.2.9-dev.238:
- (efuns.c) The OIB_NAME returned by object_info(OINFO_BASIC) did
not start with a '/' in plain mode. (reported by Fiona)
- (mud/lp-245) Added secure/master.c as a wrapper for obj/master.c for
use with plain drivers.
- (func_spec, efuns, port) Added new efun utime() (provided by
Slavis) and adapted ctime() to accepts its output.
- (settings/unitopia) Updated with new version provided by Freaky.
- (settings/default) Clean up.
14-Nov-2000 (Lars Duening)
- (strfuns, actions.c, ed.c, efuns.c, interpret.c, object.c, swap.c,
wiz_list.c) New function xstrncpy() to copy a string up to a certain
length, but without adding extra 0 padding if the string is shorter
than the given length.
07-Nov-2000 (Lars Duening) (3.3.15)
Included the remaining changes from 3.2.9-dev.237:
- (efuns.c) object_info(OINFO_MEMORY) also returns the program flags
NO_SHADOW, NO_CLONE and NO_INHERIT.
- (pkg-mysql.c) Small bugfix (thanks, Michael!)
- (settings/forgottendreams) Updated according to Michael.
- (util/[x]erq/erq.h) Around dev.220 I accidentally broke
compatibility with older erq binaries by renumbering the KEEP_HANDLE
constant - fixed that now. (reported by Coogan)
05-Nov-2000 (Lars Duening) (3.3.14)
Included the changes from upcoming 3.2.9-dev.237:
- (interpret.c) call_resolved() now accepts a destructed object as
second argument and returns 0 instead of throwing an error.
(reported by Coogan)
- (settings/tubmud) 'nosave' is now on by default.
Included the changes from 3.2.9-dev.236:
- (interpret.c) When setting up the frame for a function, resolve a
possible cross-definition first. (b-000616, b-001004)
- (interpret.c, prolang.y) Right shifts of 32 or more are now properly
defined.
- (mapping.c) Adding two mappings of different width throws an error
(reported by Holger and Fiona). (b-001010)
- (regexp.c) Added a patch by Marcus Meissner to make regexp more
compatible with 8-bit characters (thanks!).
- (simulate, interpret) Moved the catch_instruction() function into
simulate to keep aggressive optimizers from over-optimizing this
function. I hope this finally cures the catch() related crashes.
(thanks, Coogan!) (b-001010-1)
- (simulate, array.c, call_out.c, comm.c, mapping.c) Callbacks now accept
protected lvalues as arguments only if they are called just once.
Reason is that the protectors don't count references: at the first
return from a callback the lvalue would be freed even though it
is still needed.
(b-001002)
- (main.c) New driver option '--pidfile <filename>' to write the
pid of the driver into a file (suggested by Freaky).
- (backend.c) The IGNORE_BANG option to efun input_to() didn't
work (provided by Casey, thanks!).
- (pkg-mysql.c) Changed some xalloc()s into pxalloc()s to protect them
against the GC (provided by Michael Fedrowitz, thanks!).
- (interpret.c) Cosmetics to the traceback output (thanks, Coogan).
- (simulate.c) A semicolon was missing (thanks, Christian B.).
13-Sep-2000 (Lars Duening) (3.3.13)
- (func_spec, lex.c, closure.c, interpret.c, prolang.y) Added the
operators '>>>' and its cousin '>>>=' for logical right shifts.
- (interpret.c) Continued adaption.
11-Sep-2000 (Lars Duening)
- (configure) Removed no longer used option 'max-log-size' (reported
by Malcom).
09-Sep-2000 (Lars Duening) (3.3.12)
- (simulate.c) Callbacks in efuns like filter() can now take references,
too (reported by Freaky).
08-Sep-2000 (Lars Duening)
- (gcollect, heartbeat) Adapted to new string handling.
- (files.c) Corrected a control flow bug in read_file().
- (interpret) Began adaptation.
07-Sep-2000 (Lars Duening) (3.3.11)
- (simulate, call_out) Due to a flag inversion, call_out() was unable
to take lvalues as arguments. It also gave the error message
with an off argument count (reported by Thorsten).
- (files) Adapted to new string handling.
06-Sep-2000 (Lars Duening)
- (interpret) The setjmp() for a catch() instruction has been moved into
its own stack frame and eval_instruction() is called recursively
on the guarded code. This seems to prevent failures and cores
when using gcc as compiler, and doesn't hurt on other platforms
either (reported by Parsec).
05-Sep-2000 (Lars Duening)
- (xerq/socket.c) A faulty comparison caused the xerq to ignore
SOCKET_STDERR and send everything on stdout (thanks, Fiona!).
04-Sep-2000 (Lars Duening) (3.3.10)
- (mstrings) Added allocation tracing.
- (func_spec, efuns) Removed obsolete efun extract().
- (efuns) Adapted to new string handling.
03-Sep-2000 (Lars Duening)
- (ed.c) Adapted.
01-Sep-2000 (Lars Duening) (3.3.9)
- (comm, dumpstat) Adapted to new string handling.
- (mstrings) Some new functions; strings are now internally terminated
with '\0' to simply interfacing with normal C library functions.
31-Aug-2000 (Lars Duening) (3.3.8)
- (array.c) Completed adaption, also removed obsolete efun member_array().
- (backend, bitstrings, call_out, closure) Adapted to new string handling.
30-Aug-2000 (Lars Duening) (3.3.7)
- (comm.c) The driver did not fully recover from a failed INPUT_CHARMODE
notification - treating the input as in charmode even after the
failure. (b-000818)
- (array.c) Continued adaptation.
29-Aug-2000 (Lars Duening)
- (interpret.c) When reactivating a destructed master, the function
applies failed to find static functions, even though all other
master applies do (thanks, Daniel!)
29-Aug-2000 (Lars Duening) (3.3.6)
- (interpret.c, object.c) The applies to valid_seteuid() and valid_trace()
clobbered the stackpointer (reported by Freaky).
- (func_spec) The argument definitions for apply() and input_to()
were incomplete (reported by Freaky).
- (actions, sent.h) Adapted the actions to use mstrings.
- (actions, func_spec) Removed the efuns add_verb(), add_xverb(),
and the historic add_actions(fun) mode.
28-Aug-2000 (Lars Duening) (3.3.5)
- (make_func.y) Adapted the creation of stdstrings.[ch].
- (Makefiles) Adapted.
- (svalue.h) Modified the definition of svalue_t to use string_t
instead of char* for strings. Also, the string_type is gone.
- (hash) Added whashmem() which hashes a memory block of a given
length.
- (gcollect.c) Adapted the basic functions to the new stringhandler,
but not all the places where at the moment normal strings are
referenced.
- (efuns.c) Adapted debug_info() to the new string handler.
- (other files) All uses of T_STRING changed to T_OLD_STRING (which
of course doesn't exist). This way it's easier to find all
the places which have to be changed.
28-Aug-2000 (Lars Duening) (3.3.4)
- (pkg-mysql.c, configure, Makefile.in) Made the mySQL code work again.
Additionally the mysqlclient library is now part of the @PKGLIBS@
template in Makefile.in, so that utils like xerq don't have to
link it in. (thanks, Michael!)
25-Aug-2000 (Lars Duening) (3.3.3)
- (xerq/lookup.c) In the IPv6 lookup, a buffer was freed twice.
(found by Uwe and Fiona).
- (pkg-mysql, doc/..., INSTALL) Integrated the mySQL efuns into the
driver proper. They are activated on suitable hosts with the
configuration switch 'use-mysql' and, when activated, define
the macro '__MYSQL__' in LPC programs.
- (lex.c) Added new LPC defines __VERSION_MAJOR__, ..._MINOR__,
..._MICRO__ and ..._PATCH__ do exactly what you expect.
- (various files) Removed obsolete efuns: file_name(), filter_array(),
m_sizeof() and map_array(). Removed deprecated efuns:
allocate_mapping(), efun308(), filter_mapping(), map_mapping()
and mapping_contains(). They were all just aliases of other efuns
anyway.
23-Aug-2000 (Lars Duening) (3.3.2)
- Forked 3.3 off the 3.2 branch at 3.2.9-dev.227.
- (bitstrings, files) New files holding the efuns for bitstrings
and files.
- (almost all files) Rewrote the codegeneration and -interpretation,
which has these effects:
- In func_spec, non-int arguments may be given the type
'null' if the number 0 is accepted at runtime.
- The relation between instruction code and prefix byte
is now defined via a table lookup and not a shift operation.
- The old prefixes 'escape', 'tefun' and 'vefun' are gone,
instead we have 'efun0'..'efun4' for efuns with fixed
argumens, and 'efunv' for vararg efuns.
- All LPC-related and machine internal instructions are
encoded without a prefix byte.
- Almost all efuns are now tabled, drastically reducing
the size of the switch() in the interpreter.
- The types of the tabled efuns are checked at runtime
by the interpreter against the specs in func_spec
_before_ the tabled efun itself is called. This means
that the efuns only have to check against illegal
type combinations and invalid values.
- New functions to handle argument-type errors were
introduced, which print the expected and the actual
type as part of their message.
- (hosts/msdos) Dropped from the release.
- (INSTALL) Added compilation notes provided by Bruce (thanks!)
- (xerq/erq.c) The DEBUG part was missing the data to generate proper
error messages for RLOOKUPV6 requests (reported by Fiona).
- And of course I forgot for 3.3.1 to remake all the dependencies *sigh*.
23-Aug-2000 (Lars Duening) (3.2.9-dev.227)
- (util/indent/, autoconf/configure.in) The Makefile is now under
configure control, and I removed a couple of warnings.
- (util/erq/erq.c) Oops, the check for HAVE_SYS_TIME came before
machine.h was included, so it couldn't work (reported by Betram
and Fiona).
22-Aug-2000 (Lars Duening) (3.2.9-dev.226)
- (hash, stralloc) Changed a few parameters from 'char*' to 'const char*'.
- (comm.c, erq, xerq) The IPv6 lookup was totally broken - fixed it.
(reported by Holger)
20-Aug-2000 (Lars Duening) (3.2.8-dev.225 == 3.2.8)
- RELEASE 3.2.8
- (func_spec, prolang.y) Efun clonep() now accepts 'mixed' arguments.
(suggested by Fiona)
- (interpret.c) The salt-handling of efun crypt() is now compatible
with the md5 passwords of FreeBSDs libscrypt. (thanks, Gerhard!)
15-Aug-2000 (Lars Duening) (3.2.8-dev.224)
- (prolang.y) All ranges '[..<op><expr>]' caused the compiler to overwrite
memory (most of the time the compiled program) because the attributes
of <expr> weren't promoted up by the <ob>.
- (lex.c) '//' comments in the argument list of a function macro at the
point of use were not ignored and caused syntax errors. It even was
already a 'TODO' in the lexer... (reported by Croft and Parsec).
14-Aug-2000 (Lars Duening) (3.2.8-dev.223)
- (prolang.y) The range '[..-<expr>]' caused the compiler to overwrite
memory (most of the time the compiled program) because the attributes
of <expr> weren't promoted up by the '-' (reported by Mammi).
- (prolang.y) In the expression '++<ident>' the opcode for '++' was
overwritten if the <ident> required a 2-Byte index. (b-000803,
b-000810)
- (comm.c) Looking up hostname first enters the IP address as string
into the lookup table, to be replaced later by the ERQ. This neatly
handles unresolved hostnames as well (provided by LynX).
11-Aug-2000 (Lars Duening) (3.2.8-dev.222)
- (mstrings) Completed the implementation of the string module itself.
10-Aug-2000 (Lars Duening)
- (func_spec, interpret.c, efuns.c) Efun terminal_colour() can now be used
with no keyword mapping at all: it then acts as a simple wrapping
efun.
08-Aug-2000 (Lars Duening)
- (smalloc.c) Attempts to free a memory block twice are now explicitely
flagged (when compiling with MALLOC_TRACE).
- (lex.c) #else and #endif followed by uncommented text raise an error
only in pedantic mode; otherwise just a warning is generated.
- (array.c, regexp.c, backend.c) Made the handling of a regexp's memory
more resistant to errors. Especially an error during a match or the
first pass of a regexp compilation caused the memory for the last
regexp compiled being freed unconditionally, even when that last
regexp was still in use or had been freed already.
04-Aug-2000 (Lars Duening)
- (lex.c) After an include, the driver did not refill its lex buffer.
This had bad or even catastrophic results if the include failed
and the include statement was the last in the lex buffer.
(reported by Freaky)
- (lex.c) The preprocessor statements #else, #endif and #define now
check if they are followed by uncommented text. If yes, the
former two raise an error (like real C does), if no, the latter
one raises an error. (reported by Freaky)
01-Aug-2000 (Lars Duening) (3.2.8-dev.221)
- (hosts/be/Makefile, .../beyacc) The driver can now be crosscompiled
on x86 for PPC.
- (mud/lp-245) Corrected a few simul_efun definitions.
- (lex.c) '#else' was not recognized if followed by whitespace.
(reported by Bardioc and Dafire)
30-Jul-2000 (Lars Duening) (3.2.8-dev.220)
- (prolang.y) Redefinition of an inherited function with differing
arguments was not properly differentiated from a normal redefinition,
causing the redefined argument information to be lost even with
#pragma save_types in effect. (reported by Bardioc)
- (mstrings) First code for an improved string handler.
26-Jul-2000 (Lars Duening) (3.2.8-dev.219)
- (lex.c) Preprocessor keywords weren't recognized if they were
followed by a non-space character (e.g. '# if('). (reported
by Fiona).
- (object.c) Saving a mapping to a file wrote unsaveable keys like
objects as '0' into the savefile, possibly creating multiple
entries with the same key. As restore_object() didn't expect
this, svalue were simply overwritten instead of properly freed.
This lead to memory leaks. Now, non-saveable keys and their
data are completely excluded from a saved mapping, and the
restore function is more robust. (part of: b-990429, b-991123-1,
b-000104)
25-Jul-2000 (Lars Duening)
- (interpret.c, smalloc.c) Removed two warnings (thanks, Freaky!).
23-Jul-2000 (Lars Duening) (3.2.8-dev.218)
- (main.c) The removal of MAX_SMALL_MALLOCED somehow didn't make
it into the diff.
20-Jul-2000 (Lars Duening) (3.2.8-dev.217)
- (regexp.c) Errors in the regular expression leaked the memory
from temporary buffers (found by Freaky).
18-Jul-2000 (Lars Duening)
- (smalloc.c, xalloc, main.c, settings/*, configure.in)
When the system run out of memory in a small block allocation
during a GC, it tended to crash
because the interaction of the 'force_more' allocation and the
'max_small_malloced' parameter caused the allocator to free the
reserves, but to never check the freelists. Removing the
max_small_malloced parameter and slightly simplifying the
force_more logic solved the problem. As a side effect, the
commandline argument '--max-small-malloc' and the corresponding
configuration parameter are gone.
17-Jul-2000 (Lars Duening)
- (closure.c, gcollect.c, dumpstat.c, interpret.c, object.c)
Revisited the places where a NULL object->variables might
be used. Especially replace_program was suspectible to this.
- (interpret.c) Efun to_string() now accepts lambda closures
as well. sprintf() was modified to print the same information
as to_string() returns. (suggested by Fiona)
06-Jul-2000 (Lars Duening) (3.2.8-dev.216)
- (smalloc.c) Removed two warnings (thanks, Freaky!)
- (lex.c) Improved the display of the error context at line ends
or end of files.
- (configure, port, machine.h.in) Ultrix (VAX) doesn't provide
the strdup() function, so I added a check and a replacement
function. Ironically, make_func.y already has its own strdup()
for exactly this reason... (reported by Bruce).
04-Jul-2000 (Lars Duening) (3.2.8-dev.215)
- (smalloc.c) Oops, the file didn't compile.
03-Jul-2000 (Lars Duening) (3.2.8-dev.214)
- (comm.c) A DEBUG_TELNET statement was at the wrong place, dereferencing
an uninitialized variable (b-000620).
- (object.c) Forgot to delete the old ixopen() statement when making
the change in 3.2.8-dev.210, causing the driver to run out of
fds because every savefile was opened twice. (b-000630)
- (smalloc.c) Added more magic words to accomodate the increased
SMALL_BLOCK_MAX value. In addition, the magic word arrays are
indexed modulo their size in case SMALL_BLOCK_MAX is increased
over the size of the arrays again.
- (interpret.c) Made the VM Stack error messages more informative.
- (prolang.y) Provided by UNItopia: return type mismatches are by
default warnings, and in pedantic mode real errors.
- (Makefile.in) The generated Makefile ended the OBJ definition
on sane systems with a line ending in a backslash, which the
Ultrix make doesn't like. (thanks, Bruce!)
01-Jul-2000 (Lars Duening) (3.2.8-dev.213)
- (main.c) DEBUG options are printed with --options, too.
- (object.c) If a savefile can't be opened, the strerror() message
is included into the error message.
- (backend.c) If the driver runs out of fds in efun write_file(),
lex_close() is called only when there is a compilation going
on (before, it was called on every out-of-fds, which crashed
the driver if it happend outside of a compile). (reported by
Freaky)
- (comm.c) h_telnet_neg() always removed two values from the
stack, regardless of many actually were there. (b-000625)
- (interpret.c) The handling of a caught error in catch() has
been exported in a separate, non-inlineable function to
thwart overzealous optimizers. (b-000606)
- (doc/LPC/closure_guide) Clarified the creation of mappings
using #'([. (b-000217-1)
- (lex.c) lex_error_context() pays more attention to the end
of the line buffer and EOF characters - before it blindly
copied 14 characters after *outp. (b-000518)
29-Jun-2000 (Lars Duening) (3.2.8-dev.212)
- (settings/unitopia, doc/efun/count_bits) Small changes.
- (backend.c) The 'inconsistency in main loop' message is now
printed onto stdout, too.
- (main, backend.c) The state check (available when compiled with
DEBUG) can now be controlled via the commandline option
'--check-state <lvl>'.
28-Jun-2000 (Lars Duening) (3.2.8-dev.211)
- (prolang.y) Removed the shift/reduce conflict in the rules for
argument definitions: token L_VOID was ambiguous.
- (prolang.y) The argument type check stumbled over additional
arguments in a function redefinition. (reported by Bardioc)
- (interpret.c) Operator += allows to add strings and floats to ints,
as operator + already does. (reported by Croft)
27-Jun-2000 (Lars Duening) (3.2.8-dev.210)
- (closure.c) The lambda block ({ #'return }) was compiled incorrectly:
a F_RETURN0 was generated, but for the closure compiler the block
returned void, necessiting the insertion of a default value by
the surrounding block. The result was a 'Bad stack at F_RETURN' at
the final F_RETURN[0] of the lambda closure latest,
e.g. for funcall(lambda(0, ({ #'?, 1, 1, ({ #'return }) }) )).
(reported by Mat@Maethos)
- (object.c) Under Cygwin and other MSDOS filesystem systems, the
savefiles are opened in binary mode. (thanks, Bastian!) (b-000528)
16-Jun-2000 (Lars Duening)
- (pkg/mysql) Integrated the update to dev.207 (thanks, Malcom!)
14-Jun-2000 (Lars Duening) (3.2.8-dev.209)
- (settings/hyperborea) added.
- (comm.c) The default routine for answering telnet negotiation requests
forgot to clean up the LPC stack when no hook was defined, thus
eventually overwriting memory. Since this happened only with
clients which actually did negotiate options, this bug remained
undetected for quite some time. (b-000508)
- (backend.c) Since b-000508 would have been found earlier if the
LPC stackpointer had been checked for consistency, I reactivated
the check_state() mechanism in DEBUG mode.
- (lex.c, prolang.y, interpret.c) Corrected the linecounting in
combination with inline closures (found by Zora).
12-Jun-2000 (Lars Duening) (3.2.8-dev.208)
- (efuns.c) present(object) returned the environment of the object
found, not the object itself. While traditional, this behaviour
is rather illogical. (thanks, Freaky!)
- (several files) Clarified some casts.
04-Jun-2000 (Lars Duening) (3.2.8-dev.207)
- (mapping.c) Added a fatal() if the mapping size rises over 0x10000000.
This is to track down b-000218.
02-Jun-2000 (Lars Duening)
- (comm.c) Added a number of debug prints to debug the telnet machine.
The are inactive unless DEBUG_TELNET is defined.
30-May-2000 (Lars Duening)
- (doc/efun/send_imp) Added a note regarding the handling of errors
on some machines. (thanks, lynX!)
- (interpret.c) The driver now prints the last 200 instructions when
fatal()ing in DEBUG mode. In addition, the trace also lists the
absolute stack usage together with the already known relative
usage.
29-May-2000 (Lars Duening) (3.2.8-dev.206)
- (stralloc) Small improvements to the CHECK_STRING mechanism. Added
several diagnostics regarding possible refcount over/underflows.
- (stralloc) New define 'KEEP_STRINGS' prohibits shared strings
from being deallocated. While memory intensive, this is a debugging
measure to locate the 'free string not found' error.
28-May-2000 (Lars Duening) (3.2.8-dev.205)
- (configure) Remade with autoconf 2.13
28-May-2000 (Lars Duening) (3.2.8-dev.204)
- (prolang.y) Warnings are generated if the redefinition of a function
loses the 'varargs' attribute (pedantic only), or if the redefinition
makes an incompatible change to the return type. Assignment type error
messages are more informative. And the argument type warnings/errors
are now printed for the correct source line, not the one following the
function.
- (ed.c) New command 'M' to strip ^Ms from lineends (thanks, Dafire!)
- (hosts/be/Makefile) The cross-compiled executable is provided with
proper resources and file attributes (icons!).
- (doc/LPC/if) Added.
27-May-2000 (Lars Duening)
- (prolang.y) Misplaced prototypes are now a warning, not just a debug
message.
23-May-2000 (Lars Duening) (3.2.8-dev.203)
- (comm.c, util/xerq/erq.c) Corrected a type error which caused the
erq to misinterpret message lengths, resulting in overwriting
its global variables: Due to a missing sign, the driver did not
handle a blocking write() operation properly, causing the resend of
the pending data to start off at the wrong offset. In turn, the
xerq did not protect itself against invalid message lengths.
This bug only triggered when the mud tried to sent more data
to the erq at once than the connection could handle. (Thanks,
Elric!) (b-000404)
22-May-2000 (Lars Duening)
- (various files) Cleaned up a couple of documentary files.
22-May-2000 (Lars Duening) (3.2.8-dev.202)
- (prolang.y) Whenever a function is redefined, the argument types
are checked for consistency. If they differ, a warning
(error in pedantic mode) is issued. The same mechanism compares
the prototype for a function with its definition.
21-May-2000 (Lars Duening)
- (smalloc.c) Added a diagnostic to the 'Temporary out of mem'
situation, because the driver run totally out of mem before
the usual diagnostic in the allocating code is reached.
20-May-2000 (Lars Duening)
- (interpret.c) foreach() makes sure that destructed objects are
removed from arrays. Also, assign_svalue_no_free() assigns 0
to the destination if the source is a destructed object.
18-May-2000 (Lars Duening) (3.2.8-dev.201)
- (lex, prolang.y) Pragma 'pedantic' causes the compiler to treat
certain warnings as errors. Pragma 'sloppy' (the default
setting) turns the pedantic behaviour off.
- (prolang.y, simulate) parse_error(), and with it the master
lfun log_error() received a flag argument 'warn', which is
set if the passed message is a warning, not an error.
16-May-2000 (Lars Duening) (3.2.8-dev.200)
- (prolang.y) Added functions yywarn() and yywarnf() to print
warnings during the compile. They act like yyerror() except
that they don't count up parse errors.
- (prolang.y) Failure to pass enough arguments to a non-varargs
simul_efun generates a warning. I'd like to make it an error,
but then a lot of mudlibs would be unhappy.
14-May-2000 (Lars Duening) (3.2.8-dev.199)
- (ed.c) Removed an endless loop in ed_buffer_size().
08-May-2000 (Lars Duening)
- (func_spec) Efun apply() was still listed with two arguments
where only one is actually required.
- (comm.c) Removed a warning.
07-May-2000 (Lars Duening) (3.2.8-dev.198)
- (util/xerq/socket.c) In flush_queue(), the loop pointers weren't
advanced after removing a queue element.
- (doc/efun/symbol_variable) Clarified the functionality.
- (interpret.c) Efun apply(), like efun funcall(), just returns
the first argument if it is not a closure.
- (func_spec) Efun typeof() can now accepts literal references.
- (array.c) Efun transpose_array() handles mixed size subarrays
better.
- (lex.c, interpret.c, simulate.c, object.c, prolang.y) More tweaks
to the memory statistic.
- (stralloc.c) Corrected the memory statistics.
07-May-2000 (Lars Duening) (3.2.8-dev.197)
- (smalloc.c, comm.c, simulate.c) Added a few more memory statistics.
Some memory uses are still unaccounted for, including the memory
used for mallocated strings.
05-May-2000 (Lars Duening)
- (smalloc.c, efuns.c) Corrected the smalloc memory stat to count
and list the wasted memory fragments. Adapted the efun debug_info()
to return this information. Also safeguarded the dump_malloc_data()
function against allocations during this function (this lead to
confusing data).
- (lex, simulate.c) Added an output of the lexer structures to 'status'.
30-Apr-2000 (Lars Duening) (3.2.8-dev.196)
- (actions.c) Corrected the cleanup code in execute_command() to
handle the situation if the command giver is destructed during
the command. (b-000207-3)
- (lex.c) By Matthew Julius: added the preprocessor macros __DIR__
and __PATH__(). (f-990203-08)
- (main.c) Corrected a few typos in the help texts.
- (prolang.y) Corrected the type tracking when compiling the
'+' operator.
- (prolang.y) '(void)' is now accepted as empty function argument
list.
27-Apr-2000 (Lars Duening)
- (hosts/be) Adapted the BeOS port to R5.
21-Apr-2000 (Lars Duening) (3.2.8-dev.195)
- (prolang.y) Added the change required by bison.
20-Apr-2000 (Lars Duening) (3.2.9-dev.194)
- (prolang.y) Local variables can now be initialized in the
definition.
- (random.c) Another small tweak.
19-Apr-2000 (Lars Duening) (3.2.8-dev.193)
- (configure.in, configure) Oops #2, the '--with-malloc' was
applied wrongly to the config.h
- (random.c) Improved the handling of large ranges.
- (gcollect.c) Multiple references to a memblock no longer fatal()
the driver, but instead print a diagnostic.
18-Apr-2000 (Lars Duening) (3.2.8-dev.192)
- (configure.in, configure) Oops, the '--with-malloc' was not
really applied to the config.h
- (util/xerq) Added a missing variable initialisation, and corrected
the num_fd computation for select(). (thanks, Michael!)
- (settings/forgottendreams) The name of the settings file should
be used by the file itself, hm?
17-Apr-2000 (Lars Duening) (3.2.8-dev.191)
- (random.c) Improved the fitting of the raw random number into
the given range. The key is not to use the '%' operator, as
the low-order bits are distressingly non-random. (b-990217-3)
- (settings/unitopia) Updated.
- (settings/forgottendreams) Added.
- (smalloc.c) Increased the max size of a small block to 128 Bytes.
This value used to crash Unitopia, but probably only because
the tables weren't fully initialised. This has been corrected,
and with Unitopia's new system the crash vanished anyway.
- (array.c, backend.c, closure.c, comm.c, efuns.c, prolang.y, object.c,
ptrtable.c, simulate.c stralloc.c, strfuns.c, sprintf.c, xalloc.h)
Removed a number of warnings. (thanks, Freaky!)
- (util/(x)erq/erq.c) Correct the time_stamp() function.
- (util/xerq/socket.c) Corrected a type which clobbered the TCP
functionality. (thanks, Michael!)
- (pkg/mysql/sql.diff) Updated. (thanks, Michael!)
- (object.c) Got rid of the fragile 'old_format' variable; instead
format parse decisions use the read version value directly.
- (interpret.c) <mapping1> -= <mapping2> now works for <mapping2>
of any width, like the normal subtraction already does.
16-Apr-2000 (Lars Duening) (3.2.8-dev.190)
- (lotsa files) Improved to 'out of memory' error messages to state
how much memory was needed for what.
16-Apr-2000 (Lars Duening) (3.2.8-dev.189)
- (array.ch, interpret.c) Array sizes are listed verbatim in the
array structure.
- (smalloc.c) Small improvements to the aligned allocations.
15-Apr-2000 (Lars Duening) (3.2.8-dev.188)
- (doc/driver/codestyle) First version.
- (xalloc.ch) New 'standardised' memory allocator module: it simply
includes the source for whatever allocator was selected.
As a side effect, the makefile no longer needs to know
which allocator to use - the define moved into config.h .
- (smalloc.ch, driver.h) Simplified the compilation of smalloc:
the functions are now compiled as they are, and stubs are
provided for the emulation of the clib functions if
possible.
- (other files) Adapted to the new memory allocator compilation,
reducing the number of dependencies on MALLOC_smalloc.
Especially: the GC support is now tied to the macro GC_SUPPORT,
SMALLOC_(LPC_)TRACE has been renamed to MALLOC_(LPC_)TRACE,
and array always store their size with the vector structure.
- (configuration) The selection of the memory allocator can now
be done with the '--with-malloc=<value>' option of configure.
15-Apr-2000 (Lars Duening) (3.2.8-dev.187)
- (prolang.y, exec.h) Extended the bugfix from yesterday so that
inherited functions are lookup up using a proper breadth search.
14-Apr-2000 (Lars Duening) (3.2.8-dev.186)
- (prolang.y, exec.h) The compiler now keeps track which inherits
happened at the top level. When looking for a ::function() to
call, it searches until it either finds the function defined
in a first level inherit, or it takes the first definition
found on any other level. (b-000207-4, b-000411-1)
- (lex.c) Added new pragma 'weak_types' to counter the effects
of a pragma 'strict_types'. (b-000208-1)
13-Apr-2000 (Lars Duening) (3.2.8-dev.185)
- (actions.c) If the notify_fail() is a closure, it is made sure
that it won't be freed while it is executing (thanks, Gnomi!)
- (erq, xerq) The time_stamp() tried to use the driver's
get_current_time() instead of the proper time().
- (configure.in) Improved the recognition of unsupported
compiler options.
11-Apr-2000 (Lars Duening) (3.2.8-dev.184)
- (comm.c) Corrected an endless loop in lookup_ip_entry()
(thanks, Freaky!)
- (hosts/unix.h) When compiling with gcc on Amiga, the
symbol AMIGA is made undefined.
07-Apr-2000 (Lars Duening) (3.2.8-dev.183)
- (gcollect.c) Found another void-function casted to a value, this
time it's writed().
- (smalloc.c) Increasing the SMALL_BLOCK_SIZE to 32 caused
crashes in UNItopia, manifesting themselves in garbage
stack data. Reduced it back to 8.
- (settings/eotl) Updated.
- (object.c) Corrected the versoin detection in restore_object() -
the logic was reversed, but happened to work for the
current generation of savefiles. (Thanks, Casey!)
06-Apr-2000 (Lars Duening) (3.2.8-dev.182)
- (gcollect.c) Casting a the void returning function fatal()
to a value returning function caused the AIX-xlc code
generator to crash on high optimization levels.
- (lots of files) Adapted for compilation on AIX 3.4 using xlc.
Some of these changes may break the adaption previously done
by Uwe, but now at least I have a base to work from on.
06-Apr-2000 (Lars Duening) (3.2.8-dev.181)
- (lex.c, prolang.y, main.c, settings/*, configure)
The keyword 'nosave' is now optional, controlled by the setting
parameter 'enable-lpc-nosave'.
05-Apr-2000 (Lars Duening)
- (closure.c) Forgot to remove two leftover DEBUG printfs
(thanks, Coogan!).
- (object.c) Corrected one error message. (thanks, Casey!)
- (comm.c) Added Lynx' optimization for the iptable[] IP
address lookup. Main advantage is that it scales better
to large numbers of users. (thanks!)
04-Apr-2000 (Lars Duening) (3.2.8-dev.180)
- (pkg/mysql) Coogan provided the updated source files - thanks!
- (INSTALL) BeOS: Added a paragraph about the etc/hosts file.
- (settings/eotl) Added the settings for End of the Line (thanks,
Casey!).
- (util/erq, util/xerq) Added timestamps plus nametag to the
diagnostics of the erq demons.
03-Apr-2000 (Lars Duening) (3.2.8-dev.179)
- (array.c) Freaky was correct: sort_array() no longer made a copy
of the incoming array *Mateese blushes deeply*. (b-000106-3)
- (sprintf.c) Trailing pad space is not added if a newline
follows directly afterwards.
02-Apr-2000 (Lars Duening) (3.2.8-dev.178)
- (stralloc.c) Increased the hashed length from 20 chars to 100.
- (smalloc.c) Increased the number of small block sizes from 8
to 32, that is: the max small block size from 32 to 128 Bytes.
- (*.h) Removed the leading '_' from the include guards as these
are reserved for system defines.
- (interpret.c, prolang.y, swap.c) Removed pointer-mismatches
(for example char* vs. unsigned char*).
- (port.c) Implemented time_stamp() using strftime().
30-Mar-2000 (Lars Duening) (3.2.8-dev.177)
- (func_spec, prolang.y, lex.c, interpret.c, closure.c, sprintf.c)
Two new bytecodes F_NX_RANGE/F_RX_RANGE (and their lvalue
counterparts) implement the constructs [x..] and [<x..]. The
former solution of abusing other bytecodes when these constructs
were used in a closure was too unstable. (b-000106-1)
29-Mar-2000 (Lars Duening)
- (sprintf.c) Change the implementation so that the efun (s)printf()
are now re-entrant.
27-Mar-2000 (Lars Duening) (3.2.8-dev.176)
- (prolang.y) If the declaration of a new local variable in an
lvalue context (foreach()) shadowed a global identifier, the
lvalue was computed for the global identifier. And that
meant random memory accesses! (b-000221-3, b-000105-2)
- (simulate.c) execute_callback(): if an apply() fails, the
apply_return_value is now properly set to 0. (b-000113-1)
- (interpret.c, prolang.c) It is now made sure that no function
is passed more than 255 arguments (the maximum which can
be encoded in just one byte). (b-991220)
- (simulate, smalloc.c) Removed the MALLOC_STAT statistic.
26-Mar-2000 (Lars Duening) (3.2.8-dev.175)
- (actions.c) remove_action_sent(): Removed a segfault in the
DEBUG code (of all things). Thanks, Casey!
- (sprintf.c) (s)printf() didn't add padding if no
data was following the format field. This is probably a space-
saving feature, but seriously hinders some formatting tasks.
(b-000228, b-000306-5)
- (closure.c) symbol_efun(), and with it efun symbol_function(),
didn't know about #'foreach. Oops. (b-000228-3)
- (closure.c) compile_value(): #'++ was accidentally compiled
as #'--. (b-000228-4)
- (lex.c) The variable pragma_no_shadow wasn't initialized
before a new compile. (b-000103)
25-Mar-2000 (Lars Duening)
- (prolang.y) Added two %type statements which allow the use of
bison instead of byacc. (p-000205)
- (efuns.c) Efun terminal_colour() didn't handle well the combination
of indentation and forced wrapping in the middle of a word.
(b-000217-2)
- (main.c, simulate.c) Added a 'vdebug_message()' as companion to
'debug_message()', taking a va_list argument instead of the
printf() style varargs. It's needed for a proper implementation
of fatal() (I'm amazed that it didn't crash earlier).
23-Mar-2000 (Lars Duening) (3.2.8-dev.174)
- (object.c) restore_value()/restore_object() modify the value
string, which is desastrous if it's a volatile or shared
string. (b-000212-1)
- (doc/efun/strstr) Documented the negative start indices. (b-000106-2)
- (doc/efun/sort_array) Made clear that the argument array
is sorted in-place. (b-000106-3)
22-Mar-2000 (Lars Duening) (3.2.8-dev.173)
- (interpret.c) call_others on arrays crashed with empty arrays,
and failed to handle 0s gracefully. The crasher was caused
by a premature optimization of the algorithm... (b-000221).
- (closure.c) Compiling a #'foreach, <sym-array> construct didn't
check if the sym-array is non-empty (b-000228-2).
21-Mar-2000 (Lars Duening) (3.2.8-dev.172)
- (actions.c) When execute_command() called privilege_violation4(),
it passed sp+1 instead of sp as the stackpointer to use. This
lead inter_sp pointing to an uninitialized stack entry if the
privilege was denied, causing a fandango on the core. (b-000110-2)
- (interpret.c) set_bit(), clear_bit(), test_bit() did not check
if the given bit number might be negative. (b-000112)
20-Mar-2000 (Lars Duening) (3.2.8-dev.171)
- (actions.c) Revisited the 64-Bit issue and removed all casts.
- (actions.c, mudlib/sys/commands.h, doc/efun/add_action)
Corrected the behaviour of add_action() so that it is backwards
compatible again. Added symbolic defines for the flags accepted
by add_action(). Improved the manpage to include examples of how
the flags affect the command parsing. (thanks, Freaky!) (b-991230)
10-Mar-2000 (Lars Duening) (3.2.8-dev.170)
- (actions.c) Corrected a possible 64-Bit issue: a cast from (p_int)
down to (int) might have lost bits while handling an address.
- (prolang.y, lex.c) The modifier 'nosave' for variables takes
over the meaning of 'static' - the latter is still recognized
for variables, but its use is deprecated. Similar, 'nosave'
should be used instead of 'static' as inheritance
modifier.
09-Mar-2000 (Lars Duening) (3.2.8-dev.169)
- (lex.c) Added the name of the macro to certain error messages
issued during expansion. This also required a new function
lexerrorf() with obvious purpose.
06-Mar-2000 (Lars Duening) (3.2.8-dev.168)
- (doc/efun/closure_guide) Removed Tubmud'isms.
- (bugs/...) New bug reports, and the EotL patches.
04-Mar-2000 (Lars Duening) (3.2.8-dev.167)
- (interpret.c, doc/efun/tell_room) Doc corrections.
- (interpret.c) f_traceprefix called master::valid_trace() with
"trace" instead of "traceprefix".
- (doc/efun/call_out) Corrections.
- (bugs/...) Added all the bug reports since .164.
01-Mar-2000 (Lars Duening) (3.2.8-dev.166)
- (make_func.y, exec.h, backend.c, parse.c) Removed warnings.
01-Mar-2000 (Lars Duening) (3.2.8-dev.165)
- All the prvious changes since .141 are back under PRCS control.
- (hosts/be/Makefile) The dependencies on generated files
like stdstrings.h are now generated automatically as well
(requires MkDepend 1.6).
17-Dec-1999 (Lars Duening) (3.2.8-dev.164)
- (mapping.c) The callbacks for map(mapping) and filter(mapping)
were told about more arguments than actually existing on
the stack. Very stupid, but it took the Evermore lib to
find this one. (thanks, Bardioc!)
16-Dec-1999 (Lars Duening) (3.2.8-dev.163)
- (simulate.c) And of course the difference between toplevel and
normal callbacks also includes the current_object :-(
- (prolang.y) Typechecking for pre-increment/decrement on indexed
values stumbled over mixed arrays. (thanks, DiEHARD).
15-Dec-1999 (Lars Duening)
- (comm.c) Recognition of a quoted IAC in the input forgot to
change the state back to TS_DATA.
- (simulate.c) Freeing callbacks with just one arg used the wrong
pointer and crashed. (thanks, Freaky!)
- (simulate, array.c, comm.c, call_out.c, mapping.c) Argh - I
have to distinguish if a callback is called from the toplevel
(current_prog is invalid) or from a program (current_prog is
valid). (thanks, Freaky!)
14-Dec-1999 (Lars Duening) (3.2.8-dev.162)
- (pkg/mysql) Corrected a number of crashers (thanks, Bastian!)
and added the HOWTO by Karm.
- (actions.c) The recent changes activated a bit of legacy code,
which started passing the verb as part of the argument string
to NO_SPACE commands. *sigh* (thanks, Daryth!)
- (simulate, call_out.c, comm.c) The callbacks can now accept
lvalues as arguments.
Also the index returned for faulty arguments was one too
high. (thanks, Zwirch!)
- (array.c) If setting up an efun callback generates an argument
error, the proper, lower stack pointer is returned. (thanks,
Zwirch)
- (interpret.c) apply() on efun-, sefun- and operator-closures
didn't properly check the number of arguments. This wasn't
detected earlier because the related code has hardly ever
been executed. (thanks, Zwirch!)
- (comm.c) The driver telnet negotiations understands quoted
IACs now. (thanks, Amylaar!)
13-Dec-1999 (Lars Duening)
- (func_spec, array.c) Efun map() can now map an array through
a mapping; similar to how filter() works.
- (prolang.y) Indexing [..x] and [..<x] are allowed as short form
of [0..x] and [0..<x]. (f-990419)
- (prolang.y) Moved the parsing and compilation of the various indexing
forms into two dedicated rules - this greatly simplified all
the other rules which involve indexing (yes: for once a file
became shorter :-).
- (func_spec, prolang.y, interpret.c, closure.c, sprintf.c) The
ranges [x..] and [<x..] are now mapped onto [x..<1] resp. [<x..<1];
this removes the need for F_EXTRACT2 for everything but the
efun extract(). F_(PROTECTED_)EXTRACT_LVALUE are gone, too.
- (sprintf.c) Made '%O' a bit more knowledgable about the various
lvalues, but without the interpret.c-internal datastructures
the printed data is just an approximation.
12-Dec-1999 (Lars Duening) (3.2.8-dev.161)
- (array, interpret) Removed a few compilation problems.
- (ed.c) If a file can't be read on editor start, the full
message is printed.
12-Dec-1999 (Lars Duening) (3.2.8-dev.160)
- (array, simulate, mapping, interpret.c) Modified the map_() and
filter_() efuns, also sort_array() and walk_mapping(), to use
the recently introduced callback_t for their implementation.
This not only simplified the code (especially in array.c), but
also introduces a standard way how callbacks are specified in
such efuns.
11-Dec-1999 (Lars Duening)
- (actions.c, sent.h) Implemented the "short verb" usage of
efun add_action().
- (sent.h, ed) Completed the documentation of sentences.
- (sent.h, comm, simulate, other files) The interactive_t is no longer
a subclass of shadow_t; instead the latter now acts as generic
"attribute" sentence for an object, linking to an independent
interactive_t for interactive users. This makes handling interactive
connections somewhat simpler.
10-Dec-1999 (Lars Duening)
- (actions, gcollect.c) The garbage collector did not trace the
globals of actions.c under the faulty impression that they are
valid only during a command execution. However, e.g. notify_fail()
can be used outside of a command, which led to used memory being
deallocated in the GC. From there, the damage continued to spread.
(at least part of b-991123-1)
- (doc/LPC/functions) Rewritten to cover all the new features introduced
since LPmud 2.4.5.
- (interpret.c) Added check for stack overflow in the eval loop - code
like funcall(lambda(0, ({ #'({ })+({1})*10000)) could otherwise
easily crash the driver. (thanks, Zwirch!)
09-Dec-1999 (Lars Duening)
- (Makefile.in, hosts/*/Makefiles) The manual dependencies for instrs.h
were out of date. (reported by Freaky and Anders - thanks!)
- (port.c) The current time_stamp() implementation omitted leading
zeroes in the day field. (thanks, Freaky!)
08-Dec-1999 (Lars Duening) (3.2.8-dev.159)
- (closure, gcollect.c, interpret.c) The closure compile did not
handle lambdas with more than 254 constants properly: the
number of values was consistently stored in the wrong place.
A classic off-by-one, caused by the indexing from the end.
(thanks, Zora!)
07-Dec-1999 (Lars Duening)
- (pkg/mysql/) Small corrections.
06-Dec-1999 (Lars Duening)
- (mud/lp-245/obj/master.c, .../simul_efun.c) valid_write() and
valid_snoop() didn't work well with plain drivers due to the
reliance on file_name(). The master now has its own file_name().
(thanks, Andy!)
- (string_spec, make_func.y, Makefiles, sources) Tired of updated
stralloc.* in three places for every change in the common
strings table, I now define all these strings in string_spec
and modified make_func to generate stdstrings.[ch] from these.
- (interpret.c) Efun get_type_info(cl, 2) did not return the
object for closure <cl> if <cl> was a lambda or bound lambda.
(thanks, Freaky!)
05-Dec-1999 (Lars Duening)
- (interpret.c, comm.c, simulate.c, object.c) Cosmetics.
- (settings/dt2, mud/dt2/...) Created the Deeper Trouble II adaption
from the old 3.2.1@141 diffs. It compiles and seems to work,
but without the mudlib I can't tell for sure.
03-Dec-1999 (Lars Duening) (3.2.8-dev.158)
- (interpret.c) Efun query_input_pending() deref'd the wrong object,
causing a nice crash. (thanks, Michael!)
01-Dec-1999 (Lars Duening)
- (doc/efun/inherit_file) Corrected typos (thanks, Freaky!).
- (doc/efun/[]) Accidentally got lost in the last snapshot.
- (interpret.c) Removed a sneaky memory leak in transfer_pointer_range().
(thanks, Michael!)
- (func_spec) Efun functionlist() was specified to return "string*"
instead of the correct "mixed*". (thanks, Freaky!)
- (interpret.c) Improved the error messages of F_MAP_INDEX.
29-Nov-1999 (Lars Duening)
- (func_spec, comm) New efun "set_combine_charset()" to combine
characters received in charmode into strings. (f-991126-0)
- (func_spec, comm.c) Efun "set_connection_charset()" now also
accepts a string as charset specificator.
27-Nov-1999 (Lars Duening) (3.2.8-dev.157)
- (port.h) A tentative change of VAR_PROT() and VARPROT() for AIX.
- (prolang.h, prolang.y) struct s_lrvalue is now defined twice in
prolang.y, to be able to cope with a wider variety of yaccs
(especially the AIX yacc).
- (util/xerq/(erq.c, socket.c)) Forgot to change two "struct queue_s"
to "struct equeue_s".
- (stralloc.c) string_dinfo_data() used an uninitialized variable.
26-Nov-1999 (Lars Duening)
- (stralloc, gcollect.c, main, backend.c, Makefiles) When compiling
with DEBUG and CHECK_STRINGS: The structures of the shared
string table are shadows in a second table, and every string
access checks the consistency of the structures. Additionally,
with the commandline option "--check-strings" the whole string
table is checked with every backend cycle.
25-Nov-1999 (Lars Duening)
The following three changes should correct b-990430, which might have
caused b-991123-0 and b-991123-1 in turn.
- (comm.c) When accepting a line of non-negotiation text in charmode,
interactive_t.tn_start became negative after the second char.
Similar if an error occured during a very long line - here
set_noecho() used wrong indices.
- (comm.c) Charmode: when a client sent single CRs and there were no
negotiations on the same line, the CR was re-read (almost)
endlessly.
- (comm.c) Should the telnet machine receive too much data, the program
now makes sure that .command_end won't fall under .tn_start resp.
.command_start.
24-Nov-1999 (Lars Duening)
- (main.c) Commandline option "--check-refcounts" was mistakenly
marked to accept a value.
23-Nov-1999 (Lars Duening)
- (actions.c, backend.c, call_out.c, comm.c, ed.c, gcollect.c,
interpret.c, lex.c, main.c, mapping.c, object.c, prolang.y,
simul_efun.c, simulate.c, stralloc.c, swap.c, wiz_list.c)
Added the timestamp to the diagnostics. error() and fatal()
calls automatically log the timestamp. The whole situation
of what is logged where when is still a mess :-(
- (comm.c) Ups, call_function_interactive() forgot to remove
its (stack located) error recovery context from the context
stack. And it hid the leading "!" when falling through to
IGNORE_BANG handlers. (thanks, Freaky!)
- (prolang.y, stralloc) New master-apply "inherit_file()" to check
and generated the full filename from an inherit statement.
(suggested by Freaky) (f-990323-0)
- (interpret.c) free_interpreter_temporaries() now also removes
all destructed objects from the code trace (obviously only
when compiled with TRACE_CODE). Since this function is called
only from the GC, it has no further sideeffects.
22-Nov-1999 (Lars Duening)
- (sprintf.c) sprintf("%O", object) in plain mode prints the object
name with a leading "/". (thanks, Freaky!)
- (lex.c) Master apply include_file() now receives the object filename
in !compat with a leading slash; of the result, leading slashes
are ignored. Also removed a typo. (thanks, Freaky!)
- (simulate.c) Efun limited() did not give the closure the full
amount of eval ticks are requested in the call. (thanks, Freaky!)
- (mapping.c) Corrected the error handling in filter_mapping() and
map_mapping(), which are used for the filter()/filter_indices()
efuns and their map_() counterparts. (thanks, Robert!)
- (port) New function time_stamp() for use in the creation of
error and driver log messages.
21-Nov-1999 (Lars Duening)
- (simulate, gcollect.c, comm, call_out.c) Introduced the "callback"
structure, to be used for input_to()s and call_out()s. call_out.c
became really simple :-)
20-Nov-1999 (Lars Duening)
- (autoconf/configure.in, configure, port.h) Small tweaks.
- (interpret.c) Correction to sort_array(): the GET_NUM_ARG occured
too late.
19-Nov-1999 (Lars Duening) (3.2.8-dev.156)
- (efuns.c, simulate.c, swap) Added new debug_info() request DINFO_DATA:
DID_SWAP to retrieve the data usually printed as "status swap".
- (efuns.c, smalloc) Added new debug_info() request DINFO_DATA:
DID_MEMORY to retrieve the data usually printed as "status malloc".
- (typedefs.h) Just a definition of strbuf_t was missing.
18-Nov-1999 (Lars Duening)
- (comm.c, autoconf/configure.in, autoconf/acconfig.h, machine.h.in)
Added tests if F_SETOWN and SO_OOBINLINE are actually supported
by the operating system.
- (port.c, autoconf/configure.in, config.h.in, settings/{default,osb})
Added the configuration option USE_SYSTEM_CRYPT. This solves
the problem for OSB that the existing password files which have
been created with IRIX' crypt() are invalid under HP-UX's crypt().
- (efuns.c, simulate, otable, call_out, heartbeat, stralloc, rxcache)
Added new debug_info() requests DINFO_DATA, and implemented
the first sub-request DID_STATUS.
17-Nov-1999 (Lars Duening)
- (make_func.y, lex.c, efuns.c, util/xerq) Removed a few warnings when
compiling under Solaris (some remain and are caused by the
system headers); also changed the queue_t type in xerq to equeue_t
because of a clash with the Solaris queue_t type.
- (port.h, autoconf/configure.in, autoconf/acconfig.h, machine.h.in)
Added a test for ssize_t.
- (erq.c, xerq/lookup.c) Added two fixes provided by Uwe (thanks!).
16-Nov-1999 (Lars Duening)
- (comm.c, settings/osb) Removed a few warnings when compiling under
HP-UX; and the normal erq still doesn't compile there (but xerq
does).
- (func_spec, array, interpret.c) The efun sort_array() now accepts
extra arguments to be passed to the comparison function.
(suggested by Robert from Unholy Lands).
15-Nov-1999 (Lars Duening)
- (strfuns.h) Changed "ulong" to "u_long", which should be the
standard.
- (mempools) Added an include of <sys/types.h> for ssize_t.
- (settings/tubmud) Corrected some settings from "<foo>=<value>"
to the correct "with_<foo>=<value>". (thanks, Coogan!)
- (interpret.c) When apply() expanded an array, it didn't check
the elements for destructed objects. (thanks, Coogan!)
- (interpret.c) Before calling a vefun, inter_sp and inter_pc
are updated. (thanks, Michael!)
- (lex.c) Corrected an off-by-one error in the linenumbers
of an inline closure. (thanks, Michael!)
- (array.c, efuns.c, exec.h, interpret.c, prolang.y) The various
inherit types are now distinguished by a proper "inherit_type"
field in the inherit_t structure; as opposed to the former
"is_extra" flag. (provided by Michael)
14-Nov-1999 (Lars Duening)
- (smalloc.c) Added first hooks for use of madvise().
- (mud/anders) Added the diffs and extra files for the patched
3.2.1@141 driver of Deeper Trouble 2.
- (interpret.c) A return from within a foreach() crashed because
foreach's hidden "variables" messed up the stack check
in F_RETURN. (thanks, Bardioc!)
11-Nov-1999 (Lars Duening) (3.2.8-dev.155)
- (prolang.y, interpret.c, strfuns, make_func.y) The operators "&"
and "-" (and their assignment variants "&=" and "-=") may now
be applied on strings.
- (comm.c) Arguments passed to an input_to() haven't been checked
for destructed objects. (thanks, Anders!)
- (lex.c, stralloc) News master apply include_file() to generate
the full pathnames of files specified in #include directives.
10-Nov-1999 (Lars Duening)
- (mud/sticklib/) Updated the diff files.
09-Nov-1999 (Lars Duening)
- (bugs/p-990901) Updated the catch_no_log() patch. (thanks, Michael!)
- (array.c) unique_array() on an empty array crashed. (thanks, Ralph!)
08-Nov-1999 (Lars Duening)
- (simulate.c) Oops, "rename_to" has been written "rename_tp".
(thanks, Elric!)
- (gcollect.c) Added some DEBUG: printfs to check if the objects
are counted properly.
- (prolang.y) "*"::foo() now succeeds if at least one inherited
object contains this function.
- (prolang.y) The name table in get_type_name() was still incorrect.
(thanks, Michael!)
07-Nov-1999 (Lars Duening)
- (settings/default, unitopia) Updated the unitopia settings, and
commented the max. hashtable values.
- (object.c, closure.c, parse.c, sprintf.c) Removed a couple of compiler
warnings.
- (prolang.y, closure.c, switch.h) Removed a memory leak in the
compilation of top-level switch() statements.
05-Nov-1999 (Lars Duening) (3.2.8-dev.154)
- (regexp.c) In one place, FALSE was returned instead of TRUE,
making regexp()/regreplace() unfunctional (thanks, Zwirch!).
- (main, gcollect.c) writex() renamed to write_x() to avoid
a clash with AIX' writex().
- (prolang) Some more AIX adaptions: struct s_lrvalue has to
be defined after the rules (to be precise: after %union),
and yyerrorf() has to use VAR_PROT() in the prototype.
- (pkg/mysql) Added new efun db_handles() (provided by Karm).
- (strfuns.h, smalloc.c) Added the necessary changes to compile
under FreeBSD (thanks, Elric!).
- (configure.in, configure) Took out the test for "-xO2" and "-xO4".
It gave wrong results under FreeBSD, and doesn't seem to be useful
anyway.
04-Nov-1999 (Lars Duening)
- (configure) Updated it with the script created on Solaris
from the configure.in.
- (mudlib/dhrystone.c) Added Hyp's Dhrystone implementation for
test purposes (486/33MHz/Cygwin: 6.7 Dhry/s).
- (port, main.c) Cygwin's rusage() only returns 0s, so I replaced
it with the simulation also used for Amiga - this way we
at least get some time information.
- (prolang.y) "#'f == string" crashed on printing an error message
due to a lacking typename for the #'symbol.
- (closure.c) Numbers bigger than 255 in closures weren't compiled.
03-Nov-1999 (Lars Duening)
- (doc/LPC/foreach) Improved the documentation a bit.
- (make_func.y) Since Solaris doesn't know stricmp() either, and
since on Cygwin it is just a define to strcasecmp(), I just
changed my two uses of stricmp() to strcasecmp().
02-Nov-1999 (Lars Duening)
- (prolang.y) Added "foreach(x in y)" as alternative to
"foreach(x : y)" - without making "in" a reserved word.
- (interpret.c) When confronted with negative starting offsets,
strstr() returned invalid results.
01-Nov-1999 (Lars Duening) (3.2.8-dev.153)
- (efuns.c) terminal_colour() stumbled over strings starting with
a keyword.
- (closure.c) The branch-rewriting was broken in @142 - using an
invalidated variable, and rewriting only two of three branch
types weren't good ideas at all.
- (lex.c, prolang.y) Replaced the 'in' keyword in foreach()
by ':' - mudlibs already use 'in' as variable name :-(
31-Oct-1999 (Lars Duening)
- (erq.c) Small fix in the IPv6 rlookup, provided by Uwe.
- (prolang.y) Cleaned up the lvalue rules for variables a bit, and
also removed the "dangling else" shift/reduce conflict.
- (func_spec, lex.c, prolang.y, interpret.c, closure.c) Implemented
the foreach() loop construct. (f-981229-18)
29-Oct-1999 (Lars Duening)
- (closure.c) An include of stddef.h was missing here, too.
- (backend.c) In non-DEBUG mode, the interactive player wasn't set
in the backend loop. (thanks, Heiko!)
- (lex, prolang.y, simulate.c, exec.h) New program flag P_NO_SHADOW,
set by the new #pragma no_shadow, disables shadowing for a
program (suggested by Holger).
- (efuns.c) Efuns debug_info()/object_info(), xINFO_MEMORY: also print
resp. return the datasize of the object. (suggested by Freaky)
- (sprintf.c) Multiples of 10 were printed without the leading digit.
- (simulate.c) Efun rename(): the two valid_write() calls are now passed
the operation codes "rename_from" and "rename_to" instead of
"do_rename" twice. (suggested by Freaky)
- (interpret.c, func_spec) call_other() now accepts arrays of objects
and returns the call results in another array.
28-Oct-1999 (Lars Duening)
- (settings/evermore) Added.
- (make_func.y) Linux doesn't know stricmp(), but strcasecmp(). Added
ad-hoc define for that.
- (swap.c) Added missing include stddef.h.
- (Makefile.in) The high WARN setting for gcc defined -Wno-parentheses
instead of -Wparentheses.
- (doc/LPC/pragma) The pragmas no_clone and no_inherit weren't
documented.
- (smalloc.h, interpret.c) Added braces around ambigouous if-elses.
- (exec.h, prolang.y, lex.c, interpret.c) Runtime errors within inline
closures were reported with wrong line numbers. Reason is that
the normal store_line_number_info() expects line numbers to
increase and therefore ignore the #line directives used with
inline closures. Solution was to add a new LI_BACK linenumber
code plus creation function to decrement the current line counter.
(thanks, Zwirch!)
27-Oct-1999 (Lars Duening) (3.2.8-dev.152)
- (xerq/erq.c) The global variable "sockets" was not initialized.
26-Oct-1999 (Lars Duening)
- (interpret.c) In call_lambda(): moved the checks for destructed
objects to the beginning.
- (comm.c) If after an ERQ call back the object is found to be
destructed, the callback is removed even if the ERQ sent
a KEEP_HANDLE reply.
- (regexp, rxcache, array.c, backend.c, ed) Regular expressions
used from outside ed() throw errors instead of printing
error messages. (b-990523)
- (actions, func_spec) Efuns query_notify_fail(), command_stack():
the information, which object did the last notify_fail(), is
now stored and accessible. (f-990217-2)
- (access_check.c, lex.c, smalloc.c, wiz_list.c, hosts/amiga/dice30.diff)
Just for fun, and because most of the changes had been done already:
applied the remaining Amiga-diffs to the main sources.
25-Oct-1999 (Lars Duening)
- (lex.c) Newlines in strings in (: :) closures are recognized
and rejected. (thanks, Zwirch!)
24-Oct-1999 (Lars Duening)
Only two months until Christmas!
- (pkg/mysql) Added the mySQL support provided by Karm (thanks!).
22-Oct-1999 (Lars Duening)
- (lex.c) Includes caused an offset-by-one for the linenumbers.
- (comm, gcollect.c, interpret.c) input_to()s now accept closures
for functions. (f-981229-21)
- (prolang.y) Improved the ->() operator: the function name may be
the same as a local variable, may be a string given as "ident"
or a string expression given as (<expr>). (b-991019-0, f-990510,
f-990605)
- (prolang.y, stralloc) ->() again: a call_other() simul-efun is
recognized.
- (exec.h) Removed TYPE_SPACE and TYPE_TERM - nothing used them.
21-Oct-1999 (Lars Duening) (3.2.8-dev.151)
- (prolang.y) If an object is inherited virtually multiple times,
a wildcarded super call ("*::") calls it only once. (b-990217-0)
20-Oct-1999 (Lars Duening)
- (prolang.y) In virtual inherits, the check for duplicate virtual
functions forgot the take the virtuality of the duplicate into
account. (part of b-981208-3)
- (prolang.y) A virtual inherit is ignored if the program in question
has been inherited virtually before. (part of b-981208-3)
- (prolang.y, interpret.c) Simulefun may now take "varargs" type
arguments (e.g. 'x (varargs mixed arg)'). (b-990113-0)
19-Oct-1999 (Lars Duening)
Worked through a handfull of reports submitted by Rodney.
- (doc/efun/say) Clarified the exclusion rules.
- (interpret.c) Efun printf(): prints to NPCs are now sent to
catch_tell().
- (efuns.c) Prompt-closures are protected against premature
deletion when replaced while they are executing.
- (svalue.h, interpret.c, prolang.y) New macro addref_closure() to easily
increment the refcount of a closure-svalue.
13-Oct-1999 (Lars Duening)
- (efuns.c) Efun terminal_colour(): when, during a wrap, spaces were
removed from a string, this fact was not considered in the
memory-access sanity checks. (b-991012-1)
12-Oct-1999 (Lars Duening)
- (comm.c) Added another IPv6 patch. (thanks, Uwe!)
- (erq, xerq) Added the ERQ_RLOOKUPV6 request supplied by Uwe (thanks!).
07-Oct-1999 (Lars Duening)
- (comm, backend.c, gcollect.c) input_to() are now be nested when
a command is executed from within an input_to(). This is not
a real stacked input system as outlined in f-990721-0.
06-Oct-1999 (Lars Duening)
- (swap.c) Corrected a small, but fatal omission of a cast.
05-Oct-1999 (Lars Duening) (3.2.8-dev.150)
- (efuns.c) Straightened the key recognition in efun terminal_colour().
- (object) Added member object_t.load_id to be able to distinguish between
objects created at the same time.
- (func_spec, efuns) New efun clones() to find the clones of an object.
(f-990203-00, f-990203-26)
04-Oct-1999 (Lars Duening)
- (make_func.y) %tefuns specified with 'void' parameters are
now recognized as vefuns. (b-990320-0)
- (make_func.y, comm.c, ed.c, lex.c, main.c, simulate.c, swap.c)
Use of MAXPATHLEN verified.
- (prolang.y) Implemented '++<map>[<x>,<y>]'. (b-990204-1)
- (func_spec, object) New efuns save_value() and restore_value()
to encode/decode values in strings. (f-981229-19)
- (func_spec, object) Extended the efuns save_object() and
restore_object() to save and restore directly to and from
a string. Maybe this should be put into separate efuns?
(f-990203-25)
03-Oct-1999 (Lars Duening) (3.2.8-dev.149)
- (util/xerq) Commented and beautified - now that was a nice
program to work on. I left the docs/ and lpc/ files alone,
for the moment, though.
- (prolang.y) The dummy code created for undefined functions was
not aligned even with ALIGN_FUNCTIONS - the other reason
for the crash in functionlist(). (b-990819-0, see
26-Sep-99 as well)
02-Oct-1999 (Lars Duening)
- (doc/util/erq, util/erq) Commented and beautified the erq a bit.
There could be done more, but I really know better things
to do. But note that somebody (probably the folks at TubMud)
has added the socket requests to the erq. (b-981212)
01-Oct-1999 (Lars Duening)
- (simulate, smalloc) Added a malloc statistic, which is dumped
into the file MALLOCSTAT with the special command "status mstat".
- (util/overhead.c) Commented.
- (util/fundesc.c, util/make_docs/) Removed - these were programs
for the original LPmud environment.
30-Sep-1999 (Lars Duening) (3.2.8-dev.148)
- (func_spec, simulate) New efun copy_file().
- (smalloc) Commented and beautified.
29-Sep-1999 (Lars Duening)
- (simulate, efuns, other files) Commented and beautified simulate.c;
moved and removed several pieces of code which didn't belong
there.
- (prolang.y) The compiler thought, "int * string" yields int - a
really silly typo (thanks, Michael!).
28-Sep-1999 (Lars Duening)
- (exec.h, closure.c, interpret.c, object.c, simul_efun.c, prolang.y)
Changed FUNCTION_NAME into FUNCTION_NAMEP to make sure
people (like me) don't use it directly (alignment!).
- (array.c) Corrected a mis-use of FUNCTION_NAME() which could lead
to Bus Errors due to misaligned data accesses (thanks, Sunblood!)
(b-990819-0, but see 03-Oct-99 as well)
- (sprintf) Commented, beautified, and two changes: formatting erros
now throw an error(), and recursive arrays/mappings are recognized.
27-Sep-1999 (Lars Duening)
- (swap) Commented and beautified.
- (stralloc) Commented and beautified.
26-Sep-1999 (Lars Duening) (3.2.8-dev.147)
- (simul_efun) Commented and beautified.
- (wiz_list) Commented and beautified.
25-Sep-1999 (Lars Duening)
- (interpret.c) Corrected a nasty crasher in the multiplication of
arrays of malloced strings (thanks, Michael!).
- (regexp) Beautified it, but didn't add many comments.
24-Sep-1999 (Lars Duening) (3.2.8-dev.146)
- (prolang.y, lex.c, closure.c) Added #'parse_command.
- (prolang.y) Corrected a rare problem with the code generated
for '&(expr[x])' and '&(expr[<x])'.
- (prolang.y, lex, make_func, lotsa files) Finally: the lexer/compiler
tokens no longer double as machine instructions. Not only this
simplifies include dependencies, it also gets rid of that
dreadful F_OFFSET (and '%instrs' is gone again, too).
*Lars bounces happily*.
- (make_func.y, Makefile) make_func now takes arguments determining
what to create. This greatly reduces compile times after changes
to the LPC compiler. See the source of make_func.y for more details.
23-Sep-1999 (Lars Duening)
- (prolang.y, exec.h, svalue.h) Commented and beautified the compiler.
21-Sep-1999 (Lars Duening)
- (array.c, doc/efun/functionlist) Clarified that efun functionlist() does
not load objects from a name, and improved the error message
for this case.
20-Sep-1999 (Lars Duening)
- (make_func.y) Added the numeric bytecodes to the created efun_defs.c
and intrs.h - helps with debugging sometimes.
- (make_func.y, func_spec, prolang.h, closure.c, dumpstat.c efuns.c,
gcollect.c, lex.c, array.c, interpret.c, swap.c, simul_efun.c,
sprintf.c)
Added a new func_spec-type '%instrs' to distinguish the instructions
used as tokens from those which aren't. This allows less files
to depend on lang.h .
19-Sep-1999 (Lars Duening) (3.2.8-dev.145)
- (parse.c, doc/efun/parse_command) Commented and ansified.
- (parse_old.c) Beautified, but only sparsely commented.
18-Sep-1999 (Lars Duening) (3.2.8-dev.144)
- (mudlib/lp-245/obj/simul_efunc.c) Adapted to the new definition
of inherit_list().
- (stralloc) Added the parse_command() lfuns as predefined
shared strings.
17-Sep-1999 (Lars Duening) (3.2.8-dev.144)
- (mudlib/sticklib) Adapted the interpret.c.diff.
- (prolang.y) Incorrect initialisation of local blocks in inline
closures sometimes generated illegal code (thanks, Michael!).
(also b-991026-1)
- (array.c, interpret, doc/efun/inherit_list) Efun inherit_list()
now prepends the returned program names with '/'es in non-compat
mode. (thanks, Michael!)
- (configure.in, configure) Corrected (I hope!) the tests for
inet_ntoa() and ipv6 support.
- (func_spec, interpret.c, doc/efun/) Efun load_name() also accepts
strings, following a suggestion by Coogan.
16-Sep-1999 (Lars Duening) (3.2.8-dev.143)
- (efuns.c) Documented process_string().
- (closure.c, mud/lp-245/obj/master.c) Corrected small errors.
15-Sep-1999 (Lars Duening)
- (efuns, parse, func_spec, interpret.c) Moved process_string()
into efuns.c and made it a tabled efun.
14-Sep-1999 (Lars Duening) (3.2.8-dev.142)
- (closure, doc/LPC/closures, svalue.h) Ansified and documented.
- (switch.h, prolang.y, typedefs.h) Beautified and documented the
data structures used for the switch().
- (exec.h) Added macros to generate code.
- (Makefile.in) The rule running make_func did not delete instrs.h
first.
- (configure.in, configure) Corrected the probing for optimization
options.
- (hosts/unix.h) Added an additional check for the newer Cygwin
packages (the old 'gethostname' problem).
- (strfuns.h) *sigh* ulong is not a standard type - we have to
clean that up later.
19-Aug-1999 (Lars Duening) (3.2.8-dev.141)
- (prolang.y) Forgot to change one 'struct lambda' into 'lambda_t'.
- (comm.c) Corrected a wrong if() condition in efun exec().
16-Aug-1999 (Lars Duening) (3.2.8-dev.140)
- (actions.c) Oops, the marker_sentence was not given a valid type.
15-Aug-1999 (Lars Duening)
- (gcollect.c, parse_old.c, parse.h) The {clear,count}_parse_refs()
functions exist in both new and old parse_command() *duh*.
- (Makefiles) Updated all dependencies.
14-Aug-1999 (Lars Duening) (3.2.8-dev.139)
- (my-alloca.h) Removed a declaration conflict on BeOS/PPC.
- (settings/avalon) Updated.
- (comm.c) Removed a compilation warning.
- (prolang.y) Redeclaration of local scopes inside of for() statements
did not recover gracefully.
- (lex.c) If the driver is compiled for IPv6, the macro __IPV6__ is
defined.
- (autoconf/configure.in, configure) Improved tests for IPv6.
13-Aug-1999 (Lars Duening) (3.2.8-dev.138)
- (sent.h, actions, simulate, other files) Beautified the sentence
handling.
- (mud/lp-245) Added mudwho-code and explanations for non-compat masters
to the obj/master.c
- (mudlib/) Removed the old master.c, simul_efun.c and room.h.
- (comm, port.h, autoconf/*) Integrated the AIX and experimental IPv6
support provided by Uwe (thanks!).
- (object.h) Forgot to include instrs.h even though part of the
struct object depends on F_SET_LIGHT *duh*.
12-Aug-1999 (Lars Duening) (3.2.8-dev.137)
- (svalue.h) Created from old datatypes.h.
- (typedefs.h) File holding the opaque definition of several globally
used types <foo>_t (which are shortcuts for the old 'struct <foo>'s);
mainly used to decouple the header files.
- (other files) Adapted to use the <foo>_t types.
12-Aug-1999 (Lars Duening) (3.2.8-dev.136)
- (strfuns) Increased the possible size of a strbuf from 2**16 to 2**32.
- (mempools, alloca.c, Makefiles) Added mempools: specialised allocators.
- (array.c, lex.c, ptrtable) Added uses of mempools where useful.
11-Aug-1999 (Lars Duening) (3.2.7-dev.135 == 3.2.7-pre.1)
- (lpmud.prj, patchlevel.h, hosts/be/Makefile) Introduced new source
branch '<v>-<r>-<p>.*' to hold the pre-releases during the shakedown
period before the 'official' release. Features and such in these
pre's are fixed, only fixes for final bugs take place.
09-Aug-1999 (Lars Duening)
- (mapping.c) Efun m_reallocate() returned the old (freed) mapping,
not the new one.
- (interpret.c) Before every bytecode evaluation, inter_sp and inter_cp
are updated.
- (pkg/ip6-aix) AIX/IPv6 package added.
04-Aug-1999 (Lars Duening) (3.2.7-dev.134)
- (util/xerq/) Corrected a couple of typos (I hate not being able
to compile this!) (thanks, Freaky!).
- (simulate.c) Cosmetic for 'status tables': the apply-cache stat
lacked a divider.
31-Jul-1999 (Lars Duening) (3.2.7-dev.133)
- (interpret.c) '*', '*=': inter_sp wasn't set properly before error()
was called. (thanks, Michael!)
- (array, swap.c) Swapping in an array ignores the current size limit.
(thanks, Michael!)
- (efuns.c) Efun terminal_colour(): the temporary buffer for the current
line is now potentially unlimited.
- (util/xerq/) Integrated patches from UNItopia, which remove a couple
of warnings and works around the repeated closing of sockets.
(thanks, Freaky!)
30-Jul-1999 (Lars Duening)
- (efuns.c) Efun trim(): forgot a check for the string end when trimming
left. This caused trim("") to core. (thanks, Freaky!)
30-Jul-1999 (Lars Duening) (3.2.7-dev.132)
- (gcollect.c) Oops, forgot to change two calls to free_vector() into
free_array(). (thanks, Freaky!)
- (interpret.c) Efun mkmapping() could have problem with oversized
arrays.
29-Jul-1999 (Lars Duening) (3.2.7-dev.131)
- (simulate.c) I am surprised nobody complained about this one: when
an error occured, the runtime stack was unrolled too early and
left the runtime_error() apply with no valid commandgiver.
- (func_spec, simulate) New efuns set_limits(), query_limits() and
limited() to handle runtime limits. (f-981229-11)
- (backend, main, simulate): array, mapping, and file transfer limits
are all settable from commandline and through the limit efuns.
- (interpret.c, efuns.c) Code for efuns like object_info()
now use the mudlib/sys/ includes to generated their results.
- (interpret.c, prolang.y) The '*' and '*=' operators now allow
to multiply strings/arrays with numbers.
28-Jul-1999 (Lars Duening)
- (lots of files) Removed trailing spaces.
- (main, backend, lex, interpret, simulate) eval_costs are now counting
up from 0 and are tested against a positive limit. The limit can
be 0, in which case the eval costs are still counted but can grow
without limit. This is just a preparation for the oncoming code,
and might even work.
27-Jul-1999 (Lars Duening) (3.2.7-dev.130)
- (efuns.c) Efun trim() also accepts a string of characters to trim.
- (array.h, datatypes.h, closure.h, mapping.h) Moved the definitions
of non-svalues back into their associated module header files.
- (datatypes.h, stralloc.h) Wrapped setting of svalues into nice
put_<type>() macros. For once, the sources shrank a few lines
instead of growing :-)
26-Jul-1999 (Lars Duening) (3.2.7-dev.129)
- (array.h, mapping.h, object.h, and dependees) Streamline the refcount
handling in macros ref_<type>(), deref_<type>() and free_<type>().
Not necessary in terms of typesafety, they make the source a bit
more readable, and less likely that a ref++ is forgotten.
23-Jul-1999 (Lars Duening) (3.2.7-dev.128)
- (lex.c, prolang.y) The inline function variables weren't initialized
properly nor checked, leading to interesting crashes when the driver
tried to freed non-existing memory.
- (lex.c, strfuns) Rewrote the inline closure scanner to cope with
linefills.
22-Jul-1999 (Lars Duening)
- (access_check.c) A null-message could cause a random memory
write.
- (strfuns.c) Corrected a write beyond boundary.
- (lex.c) Inline function scanning: newlines didn't trigger a
buffer refill in time.
22-Jul-1999 (Lars Duening) (3.2.7-dev.127)
- (actions, func_spec) New efun 'execute_command()' implements
a low-level access to the command parser.
- (prolang.y, exec.h) New optional driver hook H_COMMAND, which
replaces the driver based command handling with its own.
(obsoletes f-990204-1 and f-990203-09)
- (make_func.y) Lookup failures yield an error message, not just
an exit(1).
- (func_spec, efuns) New efun 'trim()' to trim characters from
a string. (f-981229-24)
- (settings/) Small corrections to 'default', added 'wunderland'.
- (pkg/ip6/) Added the experimental IPv6 patch from Uwe (thanks!).
21-Jul-1999 (Lars Duening) (3.2.7-dev.126)
- (settings/) Updated the tubmud settings file, added the sticklib
file. All scripts now use 'exec' to start the configure script,
allowing more meaningful exit codes.
- (simulate.c) Caught errors now produce a tracedump on stdout/stderr
(thanks, Sunblood!).
- (mud/sticklib/) Added the StickLib changes (thanks, Doomdark!)
- (lex.c) 'check last char before :)' stumbled over Newline characters.
- (prolang.y) Inline closures: removed an interaction between typed
inline closures in untyped functions.
- (actions.c, comm) Notify-fail handling is now in actions.c, this
also means that notify-fail messages are saved over nested
commands.
- (actions.c) notify_fail is available for NPCs, too: the text
will be told to the NPC. (f-990204-5)
- (func_spec, actions) New efun 'query_notify_fail()' returns the
current notify-fail setting. (f-990217-2)
- (func_spec, actions) New efuns 'command_stack()' and
'command_stack_depth()' to query the command stack.
20-Jul-1999 (Lars Duening) (3.2.7-dev.125)
- (simulate, interpret.c, backend.c) Player command execution is now
stacked, meaning that after a command() the previous command giver,
verb, etc are restored. This does not yet extend to notify-fails
though.
- (actions.ch) New source files holds the functions related to
command parsing and action management.
19-Jul-1999 (Lars Duening) (3.2.7-dev.124)
- (prolang.y) Removed a spurious debug printf().
- (backend, call_out.c, closure.c, interpret.c, simulate.c, main.c)
Generalized the error_recovery_info stack into a runtime context stack.
18-Jul-1999 (Lars Duening) (3.2.7-dev.123)
- (settings) Updated the tubmud settings file.
- (autoconf/configure.in, configure) Unfortunately it's not just
gcc 2.8.1 on Solaris which stumble over the float/branch test.
- (prolang.y) Removed a nasty interaction between disabled local
scopes and for() statements (which unfortunately didn't manifest
itself in earlier tests). Also, the local_scopes pragmas are
check only when entering a function.
- (otable.c) The table status threatened to print some stack garbage.
- (main, config.h.in, interpret.c, array.c, mapping.c, object.c,
simulate.c) Array and mapping size limits are now commandline
options; and a setting of 0 disables the limit checks.
16-Jul-1999 (Lars Duening)
- (autoconf/configure.in, configure) Oops, a typo in configure.in
really messed up the script.
- (backend.c) Following a notice from Stefan Lichtenhagen, I removed
the safety factor '*2' from f_regreplace() - the error it avoided
was fixed in dev.28. However, if this efun should cause crashes
again, this factor is one thing to try out.
- (simulate.c) Stupid bug, the second: clone_object() checked the
P_NO_CLONE flag before swapping in the program. (thanks, Manu!)
- (lex, prolang.y) New pragma 'no_local_scopes' turns off local
scoping to cater for legacy code; the second pragma 'local_scopes'
turns it back on.
- (settings/) Added settings file for Avalon (thanks, Thorsten!)
16-Jul-1999 (Lars Duening) (3.2.7-dev.122)
- (lex, prolang.y) Added inline closures ("functionals") using the
'(: <code/expression> :)' syntax MudOS invented. As a sideeffect,
the lexer now knows the '#line <num>' directive, and identifier
names may start with '$'. (thanks, Righ!) (p-990326)
- (func_spec, interpret.c, simulate) New efun query_command() returns
the full command given by the player (thanks, Ugh!).
15-Jul-1999 (Lars Duening) (3.2.7-dev.121)
- (prolang.y) The first expression in a for() may define local variables
which scope is the whole for() statement.
- (func_spec, interpret.c) More new bitstring efuns: count_bits(),
invert_bits().
14-Jul-1999 (Lars Duening) (3.2.7-dev.120)
- (func_spec, interpret.c) New bitstring efuns last_bit() and next_bit().
(thanks, Matthew!) (f-990203-14)
- (access_allow, comm, mudlib/ACCESS.ALLOW) Access rules can take
portnumbers into account. (idea from Gokhan, f-981211)
13-Jul-1999 (Lars Duening)
- (bugs/) Cleaned up the directory a big; created summary files b-summary
and f-summary.
- (func_spec, interpret, object, doc/efun/) New efun object_time()
returns the creation time of the object. (idea from Daniel,
f-990324-2)
- (lex, prolang.y, simulate.c, exec.h) New pragmes 'no_clone' to disallow
clones of an object, and 'no_inherit' to disallow inheriting a
program. (thanks, Daniel!) (f-990324-0, p-990417-0)
- (comm.c) Error ESHUTDOWN on read yields a proper message and removes
the interactive player.
- (func_spec, interpret.c) New bitstring efuns and_bits(), or_bits(),
xor_bits(). (idea from Matthew, f-990203-14)
12-Jul-1999 (Lars Duening)
- (func_spec, interpret.c) New efuns pow(), floor(), ceil() and atan2().
- (config.h.in, configure, interpret.c) If configuration option
DYNAMIC_COSTS is enabled (default is off), string additions are more
expensive for long strings (this is handy against the killer-loop
for (s=""; s += "a"; ) ).
12-Jul-1999 (Lars Duening) (3.2.7-dev.118, 119)
- (autoconf/configure.in, configure) gcc/cc1 2.8.1 on SunOS 5.7 falls into
catatonia when compiling the float/branch-incompatibility test.
Inserted a workaround.
- (prolang.y, lex, func_spec) Scope of variables in nested local blocks
ends with the defining block as it should. The space of such variables
is reused for other local blocks. (f-990203-05)
- dev.119: Small correction: function local variables (depth 2) can't
hide function arguments (depth 1);
11-Jul-1999 (Lars Duening) (3.2.7-dev.117)
- (machine.h.in) Oops, forgot to update this.
- (Makefile.in, port.h) Compile-time define NO_INLINES turns off inlining.
- (interpret, stralloc, strfuns.c, smalloc) Straightened out the
INLINE uses.
10-Jul-1999 (Lars Duening) (3.2.7-dev.116)
- (closure.c) Removed an erroneous errormessage when creating sefun
closures with large indices (thanks, Daniel!).
- (configuration, several files) Mappings have now an upper size limit
of MAX_MAPPING_SIZE keys (defaults to 5000). (f-990708-1)
09-Jul-1999 (Lars Duening) (3.2.7-dev.115)
- (config.h.in, autoconf/configure.in, settings/default) All of
of config.h is now configurable (and is it just me, or was
the original value parsing really broken?).
- (settings/) Added files for all Muds I had a config.h of. Oh, and
the files are now scripts in themselves :-)
08-Jul-1999 (Lars Duening) (3.2.7-dev.114)
- (machine.h.in, port.h) port.h now knows about the supported
(working) architectures and how to find the host-specific include
files. HOST_INCLUDE is still recognized, but optional.
- (machine.h.in, array.h, driver.h, port.h, interpret, simulate, random):
Use SIZEOF_CHAR_P instead of SIZEOF_P_INT.
- (Makefile.in) Target 'distclean' also deletes the
config.cache/status/log files.
- (other files) Added some documentation to the new autoconfig system.
08-Jul-1999 (Lars Duening) (3.2.7-dev.113)
Checked in the changes provided by Reinhard (thanks!):
- (machine.h.in, config.h.in, configure, autoconf/) Autoconfiguration
is now based on autoconf 2. The old configuration code is in the
subdirectory config-old/ held as backup. Special features are:
- rxcache and UDP port can be enabled/disabled explicitely.
- Enabling ERQ defines a symbol ERQ_INCLUDE pointing to the
correct include file (util/erq/erq.h resp util/xerq/erq.h).
- All config.h options can be set using parameters to configure.
configure --help will print the (long) list of available options.
- (func_spec) Fixed a rare case of an erroneus inclusion of send_imp()
UDP is disabled and thus the function f_send_imp() won't be compiled.
- (comm.c) erq.h is included only when the driver is compiled for
using the erq demon.
07-Jul-1999 (Lars Duening) (3.2.7-dev.112)
- (strfuns.c) Corrected off-by-one mistakes, and the length of the
final string.
- (datatypes.h, other files) Straightened the use of STRING_VOLATILE
(purely cosmetic).
07-Jul-1999 (Lars Duening) (3.2.7-dev.111)
- (strfuns, efuns, simulate): Modified efun debug_info() to return
the status information instead of printing it. Added "malloc" as
additional second argument to the DINFO_STATUS command.
- (interpret) Efun get_type_info() returns whether a string is shared
or not.
- (simulate, smalloc): Deactivated 'debugmalloc' and
'showsmallnewmalloced' and the associated code.
- (simulate, efuns, dumpstat, interpret): Added option DINFO_DUMP to
debug_info() to implement the 'dumpallobj' and 'opcprof' command.
- (interpret.c) Efuns trace() and traceprefix() are now validated
with the master-lfun 'valid_trace()'; the master-lfun
'query_player_level()' is thus no longer needed.
- (efuns, simulate, object): Efun set_is_wizard() is now optional,
and with it the object flag O_WIZARD.
- (object, simulate, prolang, efun): Object flag O_APPROVED is gone.
06-Jul-1999 (Lars Duening)
- (comm, simulate.c) Undid the last change. Now it is legal again for
the modify_command-hook to change the command_giver; this change
stays active for the execution of the command, and the original
commandgiver is passed to the NOTIFY_FAIL hook.
- (simulate.c) The MODIFY_COMMAND hook is now called first, even
before special commands like 'status' are parsed. This allows
the hook to filter out uses of these commands.
- (strfuns) New file holding string functions (for now).
- (simulate, otable, rxcache, stralloc, efuns, call_out, heartbeat):
Rewrote the status functions to use strbufs, in anticipation to
make these special commands into real efuns.
05-Jul-1999 (Lars Duening) (3.2.7-dev.110)
- (comm.c) include of <stddef.h> was missing.
- (simulate.c) After the modify-command hook was called, the commandgiver
and current object are restored their previous setting in case the
hook changed them. (thanks, Daniel!)
04-Jul-1999 (Lars Duening)
- (closure.c) Corrected a nasty mistyping in compile_lvalue(). (thanks,
Freaky!).
- (lex.c, interpret.c) Removed two warnings.
- (doc/efun) Removed the manpage for the long-gone efun query_host_name.
03-Jul-1999 (Lars Duening) (3.2.7-dev.109)
- The driver compiles again with egcs.
- (efuns.c) Bugfix for efun terminal_colour(): terminal_colour("bla", ([
"bla":"blu"]), 1) returned "blu" instead of "bla". (thanks, Michael!)
- (efuns.c) The efun sscanf() used the wrong function to report argument
errors. (thanks, Freaky!)
02-Jul-1999 (Lars Duening)
- (hosts/be/be.h, .../Makefile, .../machine.h, other files): Adapted for
BeOS 4.5. This involved adding numerous casts to make the now pickier
compiler happy. But now egcs starts crashing...
- (efuns.c) Found another shortcoming of present_clone() (and the reason
why I didn't see errors before *blush*).
01-Jul-1999 (Lars Duening)
- (efuns.c) Fixed two nasty bugs in efun present_clone(): make_name_sane()
could return NULL, and the comparison was done against the wrong name.
- (interpret.h) To be safe, macro put_number() takes the sp as argument.
- (call_out.c) When setting current_prog for efun closures, the code
now makes sure that the program is swapped in.
30-Jun-1999 (Lars Duening) (3.2.7-dev.108)
- (mud/lp-245/obj/simul_efun.c) Duh, had a complete brainfart yesterday
when adapting present_clone() to compat mode.
29-Jun-1999 (Lars Duening) (3.2.7-dev.107)
- (doc/efun) Removed the files for the long-gone efuns find_living(),
find_player(), set_living_name(), add_worth() and wizlist().
- (doc/efun/all_environment) Corrected a typo.
- (efuns.c) Corrected a misformed condition in efun terminal_colour().
- (gcollect.c) If a swap-in fails, the GC raises a fatal error (instead
of just crashing).
- (mud/lp-245/) Added the old LP-245 mudlib, of course adapted to
this driver.
- (func_spec, efuns) New efun present_clone() to find objects with
a specific blueprint (suggested by Coogan).
29-Jun-1999 (Lars Duening) (3.2.7-dev.106)
- (exec.h, interpret.c, call_out.c) Efun-closures are now properly
identified, and call_outs to efun-closures set current_prog to the
prog of the bound object. This sources still hold some DEBUG-printfs.
28-Jun-1999 (Lars Duening) (3.2.7-dev.105)
- (interpret.c) Added some argument checks to efun terminal_colour().
- (func_spec, doc/efun/environment) Documented that efun environment()
can also take a string as argument.
- (interpret.c) 'Indexing on illegal type' no longer dumps trace (what
for did that do that any way?).
- (main, backend.c, object.c) TIME_TO_RESET and TIME_TO_CLEAN_UP are now
defaults for the runtime options '--reset-time' and '--cleanup-time'.
- (interpret.c) Reactivating a destructed didn't update the number
of listed objects.
26-Jun-1999 (Lars Duening)
- (main.c, interpret.c, smalloc.c) Cosmetics.
25-Jun-1999 (Lars Duening) (3.2.7-dev.104)
- (lotsa files) NATIVE_MODE is gone - the only real difference it made
was the restriction of command() to the current object only, and
that can be handled by a simul-efun.
- (interpret.c) Oops, privilege_violation() slightly misinterpreted
the result from the master apply.
25-Jun-1999 (Lars Duening) (3.2.7-dev.103)
- (lotsa files) EUIDS mode is now automatic since most of the code
was there in any case.
New runtime option '--[no-]strict-euids'
which enables/disables the enforcement of euids known from the native
mode. When enabled, the LPC macro "__STRICT_EUIDS__" is defined.
The default setting is defined in config.h by STRICT_EUIDS; use
of an old config.h with NATIVE_MODE defined has (for now) the
same effect.
24-Jun-1999 (Lars Duening) (3.2.7-dev.102)
- (backend, efuns.c, heartbeat, interpret.c, object, simulate,
all config.h) OLD_RESET is gone.
24-Jun-1999 (Lars Duening) (3.2.7-dev.101)
- (mudlib/sys/{trace.h,input_to.h,files.h,debug_info.h}: Added these
includes with definitions for the efuns trace(), input_to(),
file_size(), get_dir(), and debug_info().
- (interpret, efuns, func_spec, exec.h) Finished commenting the
interpreter.
20-Jun-1999 (Lars Duening) (3.2.7-dev.100)
- (interpret) to_string(object) in compat mode added a leading
slash. program_time() freed its argument before querying it.
And recombine_free_lists() is gone for good.
- (interpret, func_spec, exec.h) After a long day: more comments
added (17155 lines done, 3150 to go). In particular,
eval_instruction() is commented *phew* (but it's still big
and ugly).
18-Jun-1999 (Lars Duening) (3.2.7-dev.99)
- (interpret, func_spec, exec.h) Something new: more comments.
(12558 lines done, 5800 to go).
16-Jun-1999 (Lars Duening)
- (interpret.c) The operators +=, -=, *=, /= now accept a float left
and an int right.
- (interpret, efuns) Efun terminal_colour() moved out from the interpreter
into efuns.c. And it received comments during this move.
15-Jun-1999 (Lars Duening)
- (interpret.c) Binding an unbound lambda to two objects and destructing
the originating object freed the lambda. (thanks, Kirnan & Michael)
14-Jun-1999 (Lars Duening)
- (driver.h, port.h, all files commented so far) New type 'Bool' and its
smaller sibling 'CBool' introduced.
- (autoconf/configure.in, configure, port.h, regexp, ptrtable) Replaced
CHARBITS by CHAR_BIT, adapted the generation of CHARBIT_MASK.
- (datatypes.h, func_spec, exec.h, interpret) Something new: more
comments (8700 lines done, 9000 to go). Actually I started wrapping
the bytecode interpretation into its own types and macros, which
may increase portability, and at least make the critical places
easier to find.
13-Jun-1999 (Lars Duening)
- (array.c) Efun inherit_list() just copies the program names, but
doesn't make them shared. Since they aren't shared anyway, this
makes the function much faster. (thanks, Michael!)
- (object.c) If the H_RESET hook is a closure, a result < 0 will disable
reset for this object. (thanks, Michael!)
12-Jun-1999 (Lars Duening)
- (interpret.c, mapping.c) Both m_indices() and map()/map_mapping()
called check_map_for_destr() twice, wasting time. (thanks, Michael!)
12-Jun-1999 (Lars Duening) (3.2.7-dev.98)
- (datatypes.h, func_spec, exec.h, interpret) Oh boy: more comments
(6700 lines done, 10000 to go).
10-Jun-1999 (Lars Duening)
- (call_out.c) Adding callouts from within a callout resulted
in the new callouts inserted in the wrong place when the active
callout had an odd delay (and thus a negative 'time left' entry).
If the new call_out had a MAX_INT delay, the current callout list
was effectively disabled. (b-990214-0)
- (backend.c) Added Michaels improvement to the swapping algorithm
(thanks!).
05-Jun-1999 (Lars Duening)
- (smalloc.c) As I feared: trying to print more information about
gc'ed objects may crash the driver *sigh*.
Patches provided by Michael (thanks!):
- (backend, interpret, simulate) Improved the handling of closure hooks:
now setting a driver hook from within the hook works well, too.
- (closure.c) symbol_variable() properly recognizes objects with
pending program replacement.
- (interpret.c) dump_trace() recognizes alien lfuns properly.
- (interpret.c) Calls to alien lfun closures didn't set extern_call.
- (interpret.c) Calls to F_UNDEF closures (closures whose object
was destructed) generate a proper error message.
- (swap.c) If a closure variable was changed to F_UNDEF by the garbage
collector, the swapper now duly writes this new info into the swap file.
- (mapping.c) During a GC, mappings didn't check for changed alien lfuns.
Some more suggestions by Michael:
- (interpret.c) to_object() on F_UNDEF closures returns 0.
- (object.c) free_object() miscounted the amount of memory used by
objects.
- (simulate.c) Memory display in 'status' for objects and programs
now both display '<total> (<swapped>)' (before, only the objects
status displayed that, programs displayed '<resident> (<swapped>)' ).
- (swap.c) If variables could not be unswapped, the swapper didn't clear
them properly.
24-May-1999 (Lars Duening) (3.2.7-dev.97)
- (interpret, exec.h, heartbeat.c, comm.c, make_func.y) More comments,
really.
22-May-1999 (Lars Duening) (3.2.7-dev.96)
- (config.h, interpret.c, closure.c) Corrected some typos.
22-May-1999 (Lars Duening) (3.2.7-dev.95)
- (interpret.c) Guess what: more comments.
- (interpret.c, sprintf.c) to_string() and sprintf() stumbled over
variable closures left dangling after a replace_program(). (thanks,
Michael!)
- (prolang.y) insert_inherited: the loop for the case '*::f' tended to
clobber its own control variable 'ip', causing the omission of
function calls. (thanks, Michael!)
18-May-1999 (Lars Duening) (3.2.7-dev.94)
- (config.h, hosts/be/config.h) Increased the default for MAX_LOCAL
to 50.
- (interpret.c) Even more comments.
17-May-1999 (Lars Duening) (3.2.7-dev.93)
- (doc/efun/filter_{mapping,indices}) Corrected a wrong phrase.
(thanks, Zwirch!)
- (interpret.c) Some more comments.
16-May-1999 (Lars Duening) (3.2.7-dev.92)
- (object, backend.c, dumpstat.c, efuns.c, interpret.c, simulate.c,
sprintf.c, ../mudlib/sys/objectinfo.h, doc/efun/object_info):
New object flag O_REPLACED for objects with replaced programs,
so that clonep() stops flagging such blueprints as clones.
(suggested by Michael)
- (datatypes.h, interpret) More comments.
- (simulate.c) Streamlined the namehandling in clone_object().
14-May-1999 (Lars Duening) (3.2.7-dev.91)
- (backend.c) Removed one 'var might be clobbered' warning.
- (datatypes.h, interpret) More comments.
- (object.c) When restoring a mapping of form '([:<width>])', the <width>
is made sure to be positive. (thanks, Michael!)
13-May-1999 (Lars Duening) (3.2.7-dev.90)
- (datatypes.h, interpret) More comments.
12-May-1999 (Lars Duening) (3.2.7-dev.89)
- (interpret.c, doc/efun/...) Efun symbol_function() won't create
closures from protected lfuns of other objects. (thanks, Michael!)
- (func_spec, comm, interpret.c, config.h, driver.h, main)
query_mud_port() did not accept int arguments as documented; also,
the multiport feature is no longer optional.
- (smalloc.c) write_lpc_trace() tries to write as much information about
an object as possible, not just 'Doesn't exist anymore'.
- (interpret.c) destruct() now accepts destructed objects as arguments.
(thanks, Largo!).
11-May-1999 (Lars Duening) (3.2.7-dev.88)
- (object.c) Fixed some memory leaks on errors during a restore. (thanks,
Michael!)
- (interpret.c) Some more comments.
10-May-1999 (Lars Duening) (3.2.7-dev.87)
- (interpret.c) Removed a crasher in call_lambda() on closures of
not-inherited variables. (thanks, Michael!)
- (closure.c) Creating a symbol_variable() now protects it against
replace_program()s. (thanks, Michael!)
- (array.c, efuns.c, exec.h, interpret.c, prolang.y) Duplicate virtual
inherits are no longer listed in the result of inheritlist() and
the various statistical functions. (thanks, Michael!)
09-May-1999 (Lars Duening) (3.2.7-dev.86)
More patches from Michael:
- (backend.c, interpret, gcollect.c) interpret:call_lambda() no longer
protects closure with an extra refcount; instead old, replaced driver
hooks are stored in an array and freed by the backend (or the
garbage collector).
- (backend.c) When computing a 'real soon' swapping time for objects
with no reset, the new swap time became negative, effectively
disabling swapping for this object.
- (interpret.c) Improvement of efun terminal_colour(), reducing the number
of created shared strings.
- (simulate.c) If the loading of objects fails, the name of the object
is printed with the error message.
- (swap.c) If an object WILL_CLEAN_UP on swap in, the swapper doesn't
bother to check for the function 'clean_up'.
- (interpret.c, prolang.y) Added a couple of missing updates of
time_of_ref.
- (interpret.c) Fixed a crasher when using to_string() on an lfun
closure for a swapped program.
- (simulate.c) lookfor_object() no longer swaps in the object, instead
the caller does it when needed. As this is rather rare, the effect
should be reduced disk activity.
- (ed.c, heartbeat.c) Removed two compilation warnings for printf()
args.
04-May-1999 (Lars Duening)
- (smalloc.c) _large_malloc() didn't compile in SMALLOC_LPC_TRACE due to
a missing 'const' specifier. (thanks, Freaky!)
02-May-1999 (Lars Duening) (3.2.7-dev.85)
- (backend.c) time_of_ref is fudged only after a reset of a swapped
object, not after a cleanup. Also, if the cleanup hook is a closure,
the time_of_ref is updated manually to make sure that the cleanup
won't occur in every backend loop.
- (simulate.c) lookfor_object() sets the time_of_ref of an object if
it had to swap it in. This is useful for blueprints for inheritance
and cloning, which would thrash otherwise. (thanks, Michael!)
- (lex.c) The test against recursive calls in _expand_define() crashed
the driver if an error occured during the macro expansion and the
error handling itself called macro expansion (e.g. through the
_expand_define_() efun). For now, non-reentrant recursive calls
are allowed again.
30-Apr-1999 (Lars Duening) (3.2.7-dev.84)
- (backend.c) If reset or cleanup cause an object to be swapped in,
the time_of_ref is fudged so that the object will swap out again
pretty soon, but not immediately.
- (hosts/be/Makefile) Re-introduced cross-compiling support for x86
on PowerPC.
29-Apr-1999 (Lars Duening)
- (doc/efun/caller_stack_depth, HISTORY) Corrected two typos (thanks,
Zora!).
28-Apr-1999 (Lars Duening) (3.2.7-dev.83)
- (backend.h, closure.c, interpret.h, efuns.c) Move error_recover_info
definition into backend.h, adapting the other files, and added
a missing include to efuns.c
- (interpret, exec.h, datatypes.h) Began commenting.
27-Apr-1999 (Lars Duening) (3.2.7-dev.82)
- (heartbeat.c) 'status tables' could cause a division by 0.
Integrated a patch from Michael:
- (backend.c) process_objects() now checks if a swap was successful
before setting did_swap (since some objects won't swap).
- (interpret.c) Added some ASSIGN_EVAL_COST in critical efuns.
- (interpret.c) call_lambda() did not update time_of_ref/O_RESET_STATE
on calls. Furthermore, objects bound to (s)efun closures were not
swapped in, which caused segfaults in dump_trace().
25-Apr-1999 (Lars Duening) (3.2.7-dev.81)
- (backend.c, swap.c) Swapped-out objects are again swapped in for
reset. Skipping the call and just setting a due-time in the
swapper resulted in too few calls to reset(), especially with
small swap times. (thanks, Michael!)
- (backend.c) Removed the RESET_DEBUG code sequences.
- (interpret.c) Calls to tefuns and vefuns assign the eval costs
first.
- (sprintf.c) If possible, file:line of an offending sprintf() statement
are appended to all error messages, not just to the one printed
on stderr.
- (etc/icon-*.ppm) The Icon for the Gamedriver.
- (hosts/be/{Makefile, icon-*.raw, driver.r, driver.rscr) Added the
icon to the compiled resources.
- (heartbeat.c) Fixed a crasher which occured when a heart_beat()
function managed to remove all remaining objects from the hb list.
19-Apr-1999 (Lars Duening)
- (mapping.c) When adding mappings, the second summand was freed before
the actual addition (thanks, Daniel!).
- (doc/LPC/modifiers) added from TubMud (thanks, Fiona!).
17-Apr-1999 (Lars Duening) (3.2.7-dev.80)
- (doc/) Small changes, improved the docs to switch, references
and alists (thanks, Freaky!).
- (lex.c) Bugfix from Daniel: Variables in closure may start with '_'.
- (closure.c) Bugfix from Daniel: #'[<] indexing corrected.
- (interpret.c) unmkmapping() also accepts key-only mappings (thanks,
Holger!).
- (func_spec) Efun caller_stack() was defined to return 'int' instead
of the correct 'object *'. (thanks, Robb!).
- (driver.h, smalloc, main) Added some 'const' to 'char *' where
useful.
- (main.c, lex.c) The list of predefs copied from the commandline is
now deallocated after the defines have been entered into the
table. This removes a spurious 'small block freed' warning on
garbage collections.
04-Apr-1999 (Lars Duening) (3.2.7-dev.78-79)
- Small changes, just cosmetics.
01-Apr-1999 (Lars Duening) (3.2.7-dev.77)
- Manually copied all changes since dev.76 into the Re-Release of 3.2.6.
- (call_out.c) Undid the change that callout can call protected
functions: this inability was intentional for security reasons.
- (backend.c) The consistency check of the object list was still
active. Now the code is still there, but deactivated.
- (doc/LPC/functions, doc/efun/call_out, doc/efun/call_other) Added
a bit documentation regarding protected functions (thanks, Macbeth!).
- (interpret.c, doc/LPC/operators) Subtraction allows any width of
the subtrahend.
31-Mar-1999 (Lars Duening)
- (HISTORY, hosts/be/Makefile) Small corrections.
31-Mar-1999 (Lars Duening) -- Release 3.2.6
- Froze 3.2.6-dev.76 for release.
31-Mar-1999 (Lars Duening) (3.2.6-dev.75)
- Changed the directory structure so that the sources are no longer
in the top directory. But there's still a long way to go before
a simple 'build' in the top directory does everything.
- (doc/...) Integrated the 'driverdocs', previously maintained
by Stefan Petri (thanks!).
31-Mar-1999 (Lars Duening) (3.2.6-dev.74)
- (doc/efun/...) Typo corrections (thanks, Coogan and Freaky!)
- (array.c) map_array() did not check if objects in the array were
destructed during the execution (thanks, Righ!). (b-990329-0)
- (util/make_docs/make_docs.c) Linux-adaption was not complete
enough.
30-Mar-1999 (Lars Duening) (3.2.6-dev.73)
- (lex.c) *duh* the last change tested for COMPAT, not the correct
COMPAT_MODE define.
29-Mar-1999 (Lars Duening) (3.2.6-dev.72)
- (lex.c) __FILE__ and __MASTER_OBJECT__ return names without leading
slash in compat mode.
- (backend.c, interpret.c) Fixed some warnings.
- (doc/efun/{sizeof, widthof, load_name}) Cosmetics.
- (comm) Undefining ERQ_DEMON did not compile (thanks, Bardioc!).
- (prolang.y, object.c) The __INIT function is now protected instead
of global (thanks, Freaky!).
- (call_out.c) Efun call_out(string,...) can now call protected functions
as well (thanks, Freaky!).
28-Mar-1999 (Lars Duening) (3.2.6-dev.71)
- (object, simulate, backend.c, interpret.c, efun_defs.c, dumpstat.c
smalloc.c) Changed the object list to a double-linked list, allowing
destructed objects to be removed immediately. In itself not a big
deal, but it allows future, more sorted incarnations of the object
list.
- (heartbeat.c,h) New module holding the heartbeat related code.
- (backend, interpret, simulate) Adapted for using the new heartbeat
code. Especially the backend loop now gives preference to the
heartbeats over resets/swaps - the latter are slowed down to
one reset/swap per cycle if there is not enough time.
26-Mar-1999 (Lars Duening) (3.2.6-dev.70)
- (object, simulate, backend.c, interpret.c, efun_defs.c, dumpstat.c
smalloc.c) Changed the object list to a double-linked list, allowing
destructed objects to be removed immediately. In itself not a big
deal, but it allows future, more sorted incarnations of the object
list.
26-Mar-1999 (Lars Duening) (3.2.6-dev.69)
- (backend.c) The logic in the computation of the average heartbeat
stats was wired backwards.
- (call_out.c, closure.c, comm.c, interpret.c, lex.c, regexp.c, simulate.c)
Removed a couple of warnings when compiling under BeOS/Intel.
- (port.c) get_current_time(): 'noted_alarms' is kept up to speed with
'total_alarms'. (thanks, Michael!)
- (backend, main, lex.c, interpret.c, simulate.c, func_spec, doc/...)
After the current implementation of the free-running alarm, which
is needed by the MAX_TIME mechanism, proved unstable on some
platforms, the axe fell on this feature altogether. What started
out as a nice idea was on the best way to grow into a maze of
special cases, all ugly. Sorry, folks.
25-Mar-1999 (Lars Duening) (3.2.6-dev.68)
- (backend.c) Corrected a possible division-by-0 in the heart
beat status output (thanks, Freaky!)
- (efuns.c) Efuns copy() and deep_copy() did copy quoted arrays.
(thanks, Michael!).
- (simulate.c, otable.c) Warnings in printf again...
- (doc/efun/previous_object) Clarified the difference between
previous_object() and previous_object(0).
24-Mar-1999 (Lars Duening) (3.2.6-dev.67)
- (efuns.c) Efun deep_copy() leaked memory, and also has to copy
arrays/mappings with just one ref (thanks, Michael!)
- (backend.c) Oops, major fault in the changed efun heart_beat_info(),
writing over array limits.
- (func_spec, interpret.c, backend.c, config.h, doc/...) The
hard time limit is now by default turned off (but can be
activated on the command line). The efun get_eval_time()
was renamed to remaining_eval_time() to avoid a clash with
some mud's driver patches. See f-981229-11 and f-990324-3
for further discussion.
- (main.c, simulate.c, port.h) Fixes related to MSDOS_FS:
Compiling with Cygwin under/for Windows didn't set the define.
legal_path() was a bit too restrictive. Added the define
to the list of options printed with '--options'.
24-Mar-1999 (Lars Duening) (3.2.6-dev.66)
- (backend) Moved the heartbeat handling into process_objects()
as well, which also got rid of the clumsy heartbeat table
handling. Only the efun heart_beat_info() is slow now.
24-Mar-1999 (Lars Duening) (3.2.6-dev.65)
- (backend, gcollect.c, interpret.c, object, otable, simulate.c)
Modified the list of objects so that the head and the end are
accessible through pointers. This allowed a better handling of
resets/cleanups/swapping such that the processing can be
aborted after ALARM_TIME and continued in a later cycle. This
should get rid of reset/...-induced lags.
As a result, the reset table introduced in dev.62 is no longer
necessary, nor is the config.h constant RESET_GRANULARITY.
backend.c still contains a sanity check in the main loop,
just in case. (f-990323-1)
- (otable.c) Removed another printf-related warning.
- (main.c, simulate) The name of the master object is assured to
be sensible (no leading '/' etc) (thanks, Freaky!).
23-Mar-1999 (Lars Duening) (3.2.6-dev.64)
- (comm.c, efuns.c, interpret.c, otable.c) Removed a couple of possible
mismatches between format-strings and passed arguments.
- (hosts/unix.h, util/*) Several small tweaks for compilation under
Solaris 2. Still, the util/Makefiles need manual changes
in order to build correctly *sigh*
- (otable.c) It is now legal to call rtable_remove() with an object
which is not in the reset table - it happens when an object
is destructed during its own reset (thanks, Zwirch!).
- (interpret.c) If m_allocate() runs out of memory, a NULL 'mapping'
svalue was left on the stack -> BOOM.
- (prolang.y, simul_efun.c) Replaced bzero() by memset().
- (main.c) The memory-reserve options had one extra 'd' in the long
form (thanks, Freaky!).
- (backend.c, object.c, otable.c) Made the reset handling resistant
against errors during the evaluation of reset().
22-Mar-1999 (Lars Duening) (3.2.6-dev.63)
- (backend.c, otable.c) Small bugfixes. Deactivated, but not deleted
the DEBUG printfs.
22-Mar-1999 (Lars Duening) (3.2.6-dev.62)
- (config.h, backend.c, otable, interpret.c, simulate.c, swap.c)
Implemented new, hopefully less disruptive version of the reset
handling. To get the old handling, define OLD_RESET in config.h .
Under the new implementation, the objects are sorted by their
reset times (but grouped according to RESET_GRANULARITY) which
allows easy retrieval of the due objects. Additionally, every
backend cycle checks for due objects, but limits the number of
calls to whatever can be done in two seconds. After all, resets
are not supposed to be exact.
For now, there are a number of DEBUG printfs in the modules.
(f-990318-0)
21-Mar-1999 (Lars Duening) (3.2.6-dev.61)
- (ptrtable.c,h) New module holding a generalized version of the pointer
table formerly located in object.c
- (dumpstat.c, interpret.c, simul_efun.c, object.c) Modified to use
the new pointer table.
- (func_spec, efuns, doc/efun/...) New efun copy() for shallow copies,
and deep_copy() for deep copies. (f-981229-12)
20-Mar-1999 (Lars Duening) (3.2.6-dev.60)
- (func_spec, interpret.c) Efun clonep() now also accepts strings.
- (port.h, main.c, comm.c, ed.c, simulate.c) Made sure that MAXPATHLEN
is defined and used on all hosts for file name buffers
(thanks, Freaky!).
- (parse_old.c, prolang.y) Removed a couple of 'unwanted assignment?'
warnings.
- (lex.c) Reallocations of the defbuf are traced only when '-c' was
given on the commandline.
- (hosts/be/Makefile) Corrected a small problem in the dependency
generation which would lead to incomplete builds.
- (pkg/diff) Added the diff code from Ugh and Alfe.
- (func_spec, efuns, doc/efun/...) New efun object_info().
- (interpret.c, doc/efun/...) Efun set_next_reset() just returns
the time until the next reset when passed 0 as argument.
19-Mar-1999 (Lars Duening)
- (alloca.c) Corrected some ugly formatting.
- (func_spec, interpret.c, doc/efun/...) Nobody was really fond of
'nameof()', so it's back to 'object_name()'. Well, it was worth
a try.
- (stralloc, sprintf.c, mudlib/master_skeleton.c doc/master/...)
Renamed master apply 'object_name()' to 'printf_obj_name()' due
to the clash with the new efun object_name().
18-Mar-1999 (Lars Duening) (3.2.6-dev.59)
- (comm.c, hosts/unix.h) Fixed the broken alarm() and UDP socket handling
for Cygwin.
- (func_spec, backend, interpret.c, lex.c, config.h, simulate.c,
doc/efun/...)
Added a time-based watchdog to the interpreter: its default setting
is given by MAX_TIME in config.h, it can be specified on the cmdline
with '--max-time', the actual value is available through the
macro __MAX_EVAL_TIME__, the remaining time can be queried with
the efun get_eval_time().
- (func_spec, interpret.c) Efun notify_fail() returns 0, not void.
(f-990203-18)
- (backend.c) look_for_objects_to_swap(): The call granularity was
computed from the config.h macros, not from values set on the
command line.
- (func_spec, simulate.c, doc/efun/...) Efun set_this_player() also
accepts 0 as argument (and then simply clears this_player()).
17-Mar-1999 (Lars Duening) (3.2.6-dev.58)
- (mapping.c, otable.c, efuns.c, comm.c) Fixed a couple of warnings
sent in by Freaky.
- (func_spec, doc/efun/...) clonep() and blueprint() take this_object()
as default argument (suggested by Freaky).
- (doc/efun/{clonep, assoc, insert_alist}) Small corrections, sent
in by Freaky.
- (lex.c) Added __MAX_EVAL_COST__ as predefined macro (suggested
by Chameloid).
- (interpret.c, simulate.c) Added the file to the 'Failed to load'
error messages (suggested by Nathan).
- (mapping.c, doc/efun/...) Modified map() and filter() so that for
0-width mappings the value 0 is passed as 'data' value.
- (func_spec, interpret.c, doc/efun/...) Renamed efuns
{filter,map}_mapping() to {filter,map}_indices(). The old names
are still available as aliases.
- (func_spec, interpret.c) Renamed blueprint() to load_name(),
renamed file_name() to nameof() (the old name is still
available as alias) and introduced program_name().
16-Mar-1999 (Lars Duening) (3.2.6-dev.57)
- (mudlib/master.c, wk/diff.{c,man}) Wrong lineends. Ooops.
16-Mar-1999 (Lars Duening) (3.2.6-dev.56)
- (mapping) Improved the implementation of efun m_rewidth().
- (func_spec, interpret.c, mapping, doc/efun/filter) New
efun filter() to filter mappings and arrays. (sort of f-981229-16)
- (func_spec, mapping, doc/efun/...) Renamed m_rewidth() to
m_reallocate() - this name comes closest.
- (func_spec, interpret.c, doc/efun/...) Renamed mapping_contains()
to m_contains(). The old name is available as alias.
- (util/xerq/socket.c) Changed a wrong datasize in erq_accept(),
this should improve handling of TCP sockets (thanks, Sieni!).
- (array.c) Added an improvement to the handling of special
cases in subtract_array() (thanks, Sunblood!). (p-990316)
15-Mar-1999 (Lars Duening)
- (func_spec, mapping, doc/efun/m_rewidth) New efun m_rewidth()
to change the width of a mapping. (f-981229-08)
- (func_spec, mapping, interpret.c, doc/efun/map) New efun map()
to map arrays and full-width mappings. (sort of f-981229-16)
15-Mar-1999 (Lars Duening) (3.2.6-dev.55)
- (func_spec, interpret.c, doc/efun/m_values) Changed efun m_values()
to return any column of a mapping. (f-981229-07)
- (func_spec, interpret.c, doc/efun/widthof) New efun widthof() to
return the width of a mapping. (mentioned in f-981228-08)
- (func_spec, interpret.c, doc/efun/m_allocate) Renamed efun
allocate_mapping() to m_allocate().
- (func_spec, interpret.c, doc/efun/unmkmapping) New efun unmkmapping()
to deconstruct a mapping.
14-Mar-1999 (Lars Duening) (3.2.6-dev.54)
- (interpret.c, efuns.c) Efuns lower_case(), upper_case(), and
capitalize() try to reuse the passed string if possible
(suggested by Sunblood).
- (interpret.c, func_spec, doc/efun/caller_stack)
New efun caller_stack() (suggested by TubMud).
12-Mar-1999 (Lars Duening)
- (otable) Commented and ansified.
- (port.h, comm.c, simulate.c) __CYGWIN32__ replaced by __CYGWIN__.
(b-990204-4)
12-Mar-1999 (Lars Duening) (3.2.6-dev.53)
- (object, interpret.c) Finished commenting this module.
- (func_spec, interpret.c, efuns) New efuns abs() (thanks, Holger!),
upper_case(), all_environment(). (f-990203-20, f-990217-1)
11-Mar-1999 (Lars Duening) (3.2.6-dev.52)
- (comm, lex.c) Increased the size of the buffer for the hostname in
gethostname() from 20 to MAXHOSTNAMELEN+1 chars. The domainname
is now determined once at startup from the hostname, removing
the need for getdomainname() (which on some machines returned
the NIS domain instead of the DNS domain anyway) (thanks, Freaky!).
(p-990309-1,2).
- (configure, autoconf/configure.in, all machine.h) Added test and
define for <sys/param.h>. In return, the test for getdomainname
is gone.
- (interpret.c) F_CATCH/F_END_CATCH added the reserve to the eval_cost,
but not the assigned_eval_cost. This could lead to amazingly
high assigned_eval_cost afterwards. (thanks, Sunblood!)
- (func_spec, interpret.c) efun clonep() returns just an int. The
name of the blueprint can now be retrieved with the
efun blueprint().
- (HISTORY) Change the format a bit.
- (efuns.{c,h}) Preliminary file holding all the new efuns.
- (func_spec, efuns) New efun make_shared_string() (adapted from
TubMud).
10-Mar-1999 (Lars Duening) (3.2.6-dev.51)
- (object, dumpstat.c, interpret.c, port.h, simulate.c, exec.h)
Started commenting the object module, and adapted the other files.
- (doc/efun/*) Improved the formatting of some files.
- (prolang.y) Better error message if a local variable is declared
again.
- (mudlib/master.c) Forgot to change efun308() into set_environment().
- (config.h) SUPPLY_PARSE_COMMAND is on again by default.
07-Mar-1999 (Lars Duening) (3.2.6-dev.50)
- (filestat.h) Oops, some compiler really don't like spurious ' even
in inactive parts of the source.
07-Mar-1999 (Lars Duening) (3.2.6-dev.49)
- (backend.c, swap.c) Added missing #include "random.h" statements.
- (parse.c) old_explode_string() was missing when only F_PROCESS_STRING,
but not SUPPLY_PARSE_COMMAND was defined. Oops.
- (filestat.h) Added #error statement in case somebody defines FILE_STAT.
- (config.h) SUPPLY_PARSE_COMMAND is off by default.
- (CHANGELOG) Corrected the entry for dev.46.
- (interpret.c) m_indices() was found to lack the code for checking the
mapping for destructed objects. Somehow it vanished from 3.2-dev.46.
- (prolang.y) Cleared a variable-shadowing warning.
- (closure.c, comm.c, gcollect.c, interpret, lex.c, make_func.y,
mapping.c, object.c, prolang.y, simulate.c, swap.c)
Added pragmas for Metrowerks compiler to handle unused
variables and intentional assignments in conditions.
- (hosts/be/Makefile) Now compiles on highest warning level.
- (interpret.h, instrs.h, exec.h, make_func.y) Broke a recursive
include loop.
06-Mar-1999 (Lars Duening) (3.2.6-dev.48)
- (func_spec, interpret.c, doc/efun/load_object)
New efun load_object() to load blueprints.
- (func_spec, interpret.c simulate, doc/efun/clone_object)
Modified efun clone_object() to accept objects. (f-990305-1)
06-Mar-1999 (Lars Duening) (3.2.6-dev.47)
- (simulate.c) With logging of compilations activated, if the
compilation of an object is aborted because an inherit is missing,
the driver logs 'needs inherit' instead of 'done' on stderr.
- (main.c, object, simulate) Extended the object structure with the
field 'load_name' which gives (in !compat with leading slash)
the filename from which the object resp. a clone's blueprint was
compiled. This field is used by the clonep() efun.
- (func_spec, interpret.c, doc/efun/clonep) New efun clonep() added.
I just don't know how to handle virtual object clones with it.
(f-990203-27, sort of)
- (main.c, hosts/be/Makefile) Added comments regarding OPCPROF.
- (array, interpret.c, parse.c) Since the old explode_string() is now
static in parse.c, it was renamed to old_explode_string(). This
allows to rename new_explode_string() in array.c to explode_string().
05-Mar-1999 (Lars Duening) (3.2.6-dev.46)
- (mapping, datatyps.h, interpret, array.c) Finished commenting the
mappings module.
- (parse, interpret.c) F_DESCRIBE was never implemented, so the stubs
are gone now, too.
- (func_spec, simulate, doc/set_environment) Renamed efun308()
to set_environment(). The old name is still available for now
(and I think Hyp was the first to propose the new name). (f-981229)
- (func_spec, interpret.c, doc/set_next_reset)
New efun set_next_reset(). (adapted from Morgengrauen)
03-Mar-1999 (Lars Duening) (3.2.6-dev.45)
- (mapping, datatypes.h, array.c, main.c, interpret.c, object.c, swap.c)
More comments and cleanup of the the mapping code.
- (backend.c) No prompt is printed to interactive users if they are
already closing down. This can happen if the current command caused
the disconnection, but not destruction of the player object.
- (array, interpret.c) Applied Sunbloods optimisation of
subtract_array(), which improves the cases 'array - ({})' and
'array - ({ x })' by avoiding copies and alist operations. (p-990303)
- (util/Makefile, util/xerq/Makefile) Cosmetics.
- (util/erq.c) Applied patches from TubMud, which also introduces two
new service types 'ERQ_ACCEPT' and 'ERQ_LOOKUP'.
02-Mar-1999 (Lars Duening) (3.2.6-dev.44)
- (mapping, datatypes.h) More comments.
- (util/xerq) Added Brian Gersts 'x-erq' demon (formerly 'tw-erq') as
an alternative to Amylaar's original erq. So far it's a quick
and dirty adaption. Thanks, Brian!
- (main.c, simulate.c, gcollect.c) Removed the last FILE_STAT extra
code.
- (lotsa files): The following features are no longer optional resp.
available: (f-981229-01)
OLD_PREVIOUS_OBJECT_BEHAVIOUR: gone
OLD_EXPLODE_BEHAVIOUR: gone
FLOATS: always available
TRANSCENDENT_FUNCTIONS: always available
NO_XVARARGS: gone
MAPPINGS: always available
SUPPLY_PARSE_COMMAND is still there... for now.
01-Mar-1999 (Lars Duening)
- (prolang.y) Undid most of the patch applied yesterday, because, as
Sunblood and Chameloid pointed out, removing duplicate virtual
inherits collides with p-990217 and results in sporadic losses
of inherited functions *sigh*. However, the bugfix itself
is ok and does stay.
28-Feb-1999 (Lars Duening) (3.2.6-dev.43)
- (prolang.y) Implemented the patch for the initialisation of
virtually inherited variables (thanks, Sunblade!). (p-990227)
28-Feb-1999 (Lars Duening) (3.2.6-dev.42)
- (main.c) '--options' didn't print absolute swap paths correctly.
- (dumpstat.c, object.h, interpret.c, simulate.c) The evalcosts are
now also counted per object (in the variables ticks and gigaticks),
and of course listed in the OBJ_DUMP and the debug_info(). (adapted
from Morgengrauen)
- (filestat.c, all config.h and Makefiles) Deactived the FILE_STAT
accounting, but left the filestat.h in place for now - it might
come in handy later.
- (prolang.y) Variables in variable-only objects are now properly
initialized by __INIT() (thanks, Sunblade!).
24-Feb-1999 (Lars Duening) (3.2.6-dev.40)
- (random) New implementation using the Mersenne Twister.
22-Feb-1999 (Lars Duening) (3.2.6-dev.39)
- (sprintf.c) Increased the size of the buffer for the string to be
created from 10KBytes to 64KBytes (suggested by Woody).
- (backend.c, swap.c) reset() is not called in objects which are swapped
out or which haven't been touched since the last reset(). Also, if
an object is swapped in after its due reset time, a new reset time
is set. (adapted from Morgengrauen)
- (prolang.y) Too big mapping aggregates generate a compile time error.
(adapted from Morgengrauen)
- (interpret.c) Illegal offsets in get_line_number() no longer crash
the driver during a tracedump, but 'just' generate a diagnostic.
(adapted from Morgengrauen)
- (comm.c, telnet.h) Added telnet options for X Display location and
authentification. (adapted from Morgengrauen)
18-Feb-1999 (Lars Duening)
- (interpret.c) Bad types to [x..] ranges produce a meaningful error
message.
17-Feb-1999 (Lars Duening) (3.2.6-dev.38)
- (interpret.c, prolang.y) Applied p-990217 from Sunblood (thanks!),
which fixes b-981201 (calls to virtually inherited function lose
track where the parents variables are) and b-981208-4 (redefinitions
of virtually inherited functions). As a sideeffect, "*":: may now
call the same function repeatedly if it is virtually inherited through
different parent lines. I don't like this behaviour, but right now
I don't grok the compiler well enough to change this. Consider it
a bug!
- (interpret.c) sizeof(mapping) checks the mapping for destructed
objects first (thanks, Holger!) (b-990217-2)
16-Feb-1999 (Lars Duening) (3.2.6-dev.37)
- (be/Makefile) the generated executable is tagged with the proper
version number (using setversion).
- (interpret) sapply_int() and apply_low() take a flag argument,
allowing to override any protection by static/protected keywords.
This is used in apply_master_ob() to allow the master applies
to be static; the earlier solution of setting current_object
messed up the previous_object() relation (*doh*!), causing
security systems to malfunction. sapply() itself is now a mere
#define for sapply_int(). (b-981110-0)
15-Feb-1999 (Lars Duening) (3.2.6-dev.36)
- (INSTALL) A few small changes (thanks, Patrick!).
- (my-rusage.h) Added an extra check for HPUX; I hope it uses the
correct definition of timeval now for RUSAGE_TIME (thanks, Gum!).
(b-990203-3)
- (prolang.y) Corrected wrap-around problem when programs larger
than 64K are compiled (thanks, Daniel!).
- (call_out.c, interpret.c) Whenever a callout on an efun closure occurs,
current_prog is set to NULL. Should an error occur, the dump_trace()
will recognize this value and not try to derefence it (what caused
the bugs p-990203-1 and b-990207 in the first place). The previous
fix to this problem didn't quite work because it ignored that
ob->prog might have been swapped out. However, should more places
crop up where current_prog has to be tested for NULL, introducing
a fake struct program for efun closures might be the better solution
in the long run (as suggested by p-990203-1, second patch).
- (interpret.c) Added new function push_valid_ob(object) which pushes
the given object onto the vm stack, unless the object is destructed
in which case the number 0 is put onto the stack. This function is
used in various places to protect apply_master_ob() against destructed
objects (esp. calls to privilege_violation(), heart_beat_error(),
valid_read() and valid_write()) (thanks, Sunblood!) (b-981226-0).
- (interpret.c) apply_master_ob() temporarily sets current_object to
the master object, allowing the master functions to be static.
10-Feb-1999 (Lars Duening) (3.2.6-dev.35)
- (call_out.c) Callouts did not set up current_prog, this caused
the tracedump to crash should an error occur in a callout to
an efun closure (thanks, Sunblood and Logic!) (p-990203-1,
b-990207).
- (call_out.c) Callouts no longer confuse 'command_giver destructed
meanwhile' with 'no command_giver to begin with' (thanks, Sissi
and Tmm!) (b-990106-0, b-990204-0)
- (closure.c) Made #'++/#'-- work (thanks, Zwirch!) (b-990204-3).
- (comm.c) During logon, current_interactive is set to the
object itself (thanks, Daniel!) (p-990203-3).
- (comm.c) When doing I/O, no output is sent to destructed snoopers
(thanks, Zwirch!) (b-990204-2).
- (Makefile) Updated dependency generation for mkdepend 1.5.
- (interpret.c) terminal_colour: Fixed a memory leak of the stack
arguments and auxiliary strings - on Tubmud the leak was severe
enough to make the GC last several hours (thanks, Sunblood!)
(p-990203-0, b-990203-1)
- (interpret.c) If adding to an array caused it to hit the upper limit,
its memory was freed nevertheless. Subsequent accesses caused all
sorts of interesting effects (thanks, Daniel and Zora!) (p-990203-2,
b-990203-5).
- (interpret.c) terminal_colour() correctly wraps strings of one less
the wrap limit (thanks, Chameloid!) (b-990210).
- (interpret.c) A call_lambda() on a CLOSURE_IDENTIFIER makes sure
that the variable is swapped in (thanks, Sunblood and Matthew!)
(b-990203-0, b-990203-6).
- (func_spec, interpret.c) to_int(), to_object() and to_float() accept
their target data type as argument (thanks, Zora and Zwirch!)
(b-980922-0, f-980928-0).
- (prolang.y) Applied a patch fixing a potential crasher (thanks, Daniel!)
(p-990203-5).
- (sprintf.c) Added guards against values < 1.0 to the use of log10
when estimating the number of digits to print (thanks, Chameloid!)
12-Dec-1998 (Lars Duening) (3.2.6-dev.34)
- (make_func.y, Makefiles) The file efun_defs.c is written directly
my make_func, not just dumped to stdout. The generated lang.y
now bears a notice that the file is generated automatically.
- (mapping) First comments added.
10-Dec-1998 (Lars Duening) -- Release 3.2.5
- Froze 3.2.5-dev.33 for release.
09-Dec-1998 (Lars Duening) (3.2.5-dev.32)
- (make_func.y, func_spec) Commented and ansified.
08-Dec-1998 (Lars Duening)
- (lex.*) Commented and ansified.
- (comm.c) At the end of a session the driver does no longer
send 'Closing down' to the socket.
07-Dec-1998 (Lars Duening)
- (simulate) New function check_no_parentdirs() checks a pathname
for parent dir specifications (e.g. '/../').
- (sprintf) This is actually an old change, but I forgot to log
it at that time: increased the size of an internal buffer
used to print float numbers to prevent crashes with big floats.
Additionally the code tries to estimate and adjust the size of
the output before it prints the float, and tests for a buffer
overrun and aborts the driver with a fatal() if it happens
(b-980420).
06-Dec-1998 (Lars Duening) (3.2.5-dev.29)
- (port.h) When compiling with the GNU compiler, _GNU_SOURCE is
defined.
- (swap.c) A seek error when trying to write a (new) block to
the swap file is no longer a fatal() error.
- (Makefile.in, util/Makefile) A normal make in util/ no longer
attempts to install the binaries. To do that, use the target
'install' in util/ or 'install-utils' in the main directory.
04-Dec-1998 (Lars Duening)
- (ed.c) Oops, had an embedded \0 character in a help text.
- (main.c) The version number printed on --version and --options
now distinguishes real releases and development versions.
- (simulate.c) legal_path() uses a refined test for '..'-directory
specifications, now being able to tell these apart from harmless
uses like '..file' or '...' (thanks, Fiona!).
03-Dec-1998 (Lars Duening) (3.2.5-dev.28)
- (backend.c) f_regreplace(): reallocation-condition was 'space < 0',
instead of 'space <= 0' which could cause memory writes just one
byte beyond the allocated block (b-981202-2).
- (interpret.c) dump_trace() and get_line_number() lacked the handling
of ALIEN_LFUN_CLOSURE calls, signified by a 0-valued pc on the
control stack. This caused runtime errors in funcalls to
symbol_function()s to crash in the error handling.
02-Dec-1998 (Lars Duening) (3.2.5-dev.27)
- (lotsa files) Replaced tab characters with spaces.
- (comm.c) Under Linux, a special handler is used to ignore SIGPIPEs,
since the provided SIG_IGN is just a one-shot handler (thanks,
Blackcat!).
01-Dec-1998 (Lars Duening) (3.2.5-dev.26)
- (main.c, ed.c, port.h) Cosmetics.
- (simulate.c) Efun command() now returns 0 when the target object
or the current object are destructed.
Similar, the handling for a string H_MODIFY_COMMAND hook did
not check if the command_giver is destructed. If the gamedriver
was compiled with -DDEBUG, this caused a fatal error 'apply()
on destructed object'.
- (interpret.c) call_lambda() increments the refcount of lambda
closures while executing their code. This is important
for driver hook closures which may first destruct and then
reload the master. Without the refcounting, this would delete
the bytecode while it is executed (thanks, Sunblade!).
- (patchlevel.h)
Correcte the automatic generation of release dates.
30-Nov-1998 (Lars Duening)
- (closure.c) Compensated a (propable) optimizer error for Linux/gcc.
See C_COMPILER_BUGS for details.
- (port.h) The replacement define for strrchr() was faulty.
27-Nov-1998 (Lars Duening) (3.2.5-dev.25)
- (simulate.c) One line was lost in error(), messing up the
command_giver in a heart_beat error.
- (interpret.c) Experimented with the TubMud patch to mark
efun closures by clearing csp->prog. However, the driver
interprets this value as 'bottom of cs stack' and thus
gets confused in F_RETURN and propably other places, too.
25-Nov-1998 (Lars Duening) (3.2.5-dev.24)
- (comm.*) Commented and converted to standard C. Also removed
the portal fragments - they didn't work anyway.
- (call_out.*, dumpstat.*, ed.*, gcollect.*) Commented and converted
to standard C. Also improved a few of the helpfiles of the
editor.
- (my-rusage.h, port.*, comm.*, hosts/be/be.h) Resolved some minor
issues under BeOS/x86.
- (main.c) Fixed a small problem in the option parsing.
- (object) The program renumber moved in here from gcollect.
21-Nov-1998 (Lars Duening)
- (hosts/fcrypt) Removed.
- (comm.c) Renamed from comm1.c
20-Nov-1998 (Lars Duening)
- (lotsa files) MSDOS support removed. Parts of the driver wouldn't
compile under MSDOS anyway. However, the support for the MSDOS
filesystem is still there.
19-Nov-1998 (Lars Duening)
- (comm1.c, config.h) The ERQ send buffer size is now configurable
in config.h, too. Also, the default size is now 1KByte for
better throughput.
- (lex.c, main.c) New defines __ERQ_MAX_SEND__ and __ERQ_MAX_REPLY__ if
if compiler is defined for ERQ support.
Both changes are taken from the x-erq distribution of Brian Gerst.
- (driver.h) If CATCH_UDP_PORT is not defined, UDP_SEND is made
undefined, too.
18-Nov-1998 (Lars Duening)
- (lex.c) Compat mode drivers define __COMPAT_MODE__ (meant to
replace COMPAT_FLAG eventually); native mode drivers define
__NATIVE_MODE__. Similar, a driver using euids defines __EUIDS__.
- (access_check.c) Sometimes the "Can't stat ACCESS_FILE" message
was generated for no reason.
- (mudlib/test_master.c) Extended the master to use normal
add_actions().
15-Nov-1998 (Lars Duening)
- (comm1, sent.h, simulate) Began ansification of comm1.c .
Moved the definition of the input_to structure from sent.h
to comm1.c
- (Copyright, CREDITS) Some cleanup.
11-Nov-1998 (Lars Duening)
- (smalloc.c) Ups, srealloc() must not be static when compiling
with SBRK_OK, as it implements the realloc() function then.
- (interpret.c, simulate.c) Added some #ifdef DEBUG...#endif
statements where appropriate.
- (gcollect) Variable time_last_gc was not visible when compiling
with MALLOC_sysmalloc.
10-Nov-1998 (Lars Duening)
- (interpret.c, my-rusage.h, port.h) A few changes to accomodate
SunOS4.
- (lex.c) Only regular files can be used as include files; before
it was possible to include directories.
09-Nov-1998 (Lars Duening)
- (lex.c) Replace the alloca()d buffers in _expand_define() with
once-xalloc()ed ones. In DEBUG mode, recursive calls to
_expand_define() are caught.
- (lex.c, patchlevel.h) Non-release versions have a version number
of the form '3.2.5-dev.16'.
- (interpret.c) Corrected an off-by-one error in the stack handling
of mapping_contains() (b-980922-1).
08-Nov-1998 (Lars Duening)
- (my-alloca.h) If alloca.c is used, the system alloca files
are not included - in most cases they define alloca() to
something which is not covered by alloca.c, kind of spoiling
the desired effect.
- (lex.c) If alloca.c is used, a call to alloca(0) is made after
each use of _expand_define(), to keep the memory usage low.
- (hosts/be/machine.h, .../Makefile)
alloca.c is no longer used.
04-Nov-1998 (Lars Duening)
- (access_check.c) If the ACCESS_FILE can't be read, an error
message is printed to stderr.
- (comm1.c) Sorted out the BeOS blocking socket problem.
03-Nov-1998 (Lars Duening)
- (func_spec, interpret.c, prolang.y) F_SWAP and F_BREAK_POINT
are compiled in only when the efuns are actually defined.
By default, they aren't.
- (simulate.c) Removed the remaining debug outputs.
- (closure.c) The branch rewriting code, responsible for changing
BRANCHes into LBRANCHes when a closure grows big in size, did
not correct 16-Bit offsets for the new target addresses of new
code. The applied fix solves the problem for UNItopia (using <>
as #include specifier), but might not be sufficient for all
cases. Therefore, two DEBUG: messages remain to warn if this
feature is used.
- (hosts/be/*) Adapted for R4/x86.
- (*.c) Removed most of the 'Possibly unwanted assigment' warnings.
02-Nov-1998 (Lars Duening)
- (simulate) Corrected bugs in make_name_sane() and load_object().
The debug outputs are still in place for now (b-981029-0).
01-Nov-1998 (Lars Duening)
- (hosts/be/Makefile) Adapted to BeOS R4.
- (simulate) The functions find_object() and find_object2() are
merged into one function lookfor_object(). For the old calls
the macros get_object() and find_object() are available
(note the subtle shift in naming!). This reduces the number
of calls to make_name_sane().
The function load_object() is no longer exported.
- (simulate) Rewrote the load_object() to use a loop for the
iterative compilation process instead of tail recursion.
- (patchlevel.h) Automatized the versioning to use PRCS keywords.
- (comm1.c) After processing a received UDP packet, the evalution
costs are cleared (thanks, Tucita!) (p-981027-0).
- (main.c) The argument parser printed the wrong option in
one error message (b-980925-1).
- (config.h, hosts/*/config.h) Increased the limit for bit strings
to 6144 Bits (using 1KB memory).
- (interpret.c) Out-of-bounds error message for the bit efuns printed
garbage instead of the faulty bitnumber (b-980925-0).
09-Oct-1998 (Lars Duening)
- (array.c, backend.c) Added some checks if memory allocations
actually succeed.
23-Sep-1998 (Lars Duening) -- Release 3.2.4
- (simulate.c) load_object() The code cleaning up the filename did
not check if an object with the 'sane' filename already exists.
This lead to duplicate entries in the object table and thus
fatal driver aborts. Furthermore, the code carelessly modified
the string passed, causing disruptions in the shared string
table.
- (doc/efun/terminal_colour, doc/efun/query_mud_port) added.
22-Sep-1998 (Lars Duening)
- (filestat.*) Oops, the one statistic necessary to detect multiple
uses of a file in one command was missing. Corrected that.
21-Sep-1998 (Lars Duening) -- Release 3.2.3
- (array.c) Changed order_alist() to use standard conformant pointer
arithmetics.
- (backend) Added the statistic 'total_player_commands'.
- (filestat.*) Statistics module counting the number and type of
file usages (read, write, delete, read for compilation, read
for inclusion, read for restore_object, write for save_object).
The statistic is enabled by defining FILE_STAT in config.h.
The statistic is appended to the file /FILESTAT when the
special command 'status files' is given.
- (access_check.c, backend.c, comm1.c, dumpstat.c, main.c, gcollect.c,
lex.c, main.c, object.c, simulate.c, various Makefiles)
Adapted for filestat.
- (main.c) Beautified the --options output.
- (swap.*, main.c) New commandline option '--swap-compact' to put
the swapper in the "compact mode". In this mode, free space in
the swapfile is reused immediately; in contrast to the default
mode in which the reuse is determined by low/high watermarks.
20-Sep-1998 (Lars Duening)
- (interpret.c) F_MAPPING_CONTAINS returned destructed objects since
it didn't check the results of get_map_lvalue() properly (thanks,
Fiona and Zora!).
- (backend.c) Reallocation of the heartbeat array now conforms more
to the standard.
14-Sep-1998 (Lars Duening) -- Release 3.2.2
- (array.c) One statement was at the wrong place in order_alist(),
causing a malfunction in explode().
- (closure.c) store_case_labels(): another crasher removed, this
time two loops assumed that the variables local to their body
keep their values between two iterations.
- (interpret.c) As in closure.c, loop body variables are moved
outside their loops if they are meant to be persistant.
- (interpret.c) A misplaced cast broke sscanf().
- (backend.*, hash.*) Beautified and commented.
- (main.*) Marked the boolean commandline parameters as such.
The gamedriver announces itself as 'LDMud'.
- (patchlevel.h) Changed version number from 03.02.1@<patchlevel>
to 3.2.<patchlevel> (note the missing leading zeroes!).
- (CHANGELOG) renamed from CHANGELOG.OSB.
- (HISTORY) new file for a user-oriented summary of the changes.
10-Sep-1998 (Lars Duening)
- (alloca.c) Beautified.
- (simulate.c) load_object: Extended the sanity checks for filenames
a bit: multiple '/' are collapsed into just one (thanks for the
idea, Zora!).
05-Sep-1998 (Lars Duening)
- (main.c) Oops, small typo in options() (thanks, Woody!).
And the short command options are now case sensitive as they
should be.
- (closure.c) Omission of a seemlingly harmless cast caused
the driver to core when compiling a switch. Unfortunately, my
simple test_master.c didn't catch this. *sigh* We need a proper
testsuite...
- (ed.c, interpret.c, lex.c, mapping.c, parse.c, prolang.y, sprintf.c)
Checked for and corrected similar casts.
- (swap.c) Re-added Macbeth's watermark handling for the reusage
of free-space, though for now it's deactivated .
- (*.c, *.y) Added some parentheses as suggested by gcc to make the
code clearer.
- (comm.*, interpret.c) Replace the define MESSAGE_FLUSH by the
variable message_flush, keeping gcc happier.
- (prolang.y) Bugfix from mubo@silicondream: If a program defined
__INIT() but didn't implement it, later inheriting of this
program crashed the driver.
- (port.h, interpret.*, prolang.*, stralloc.*) New macro LOCAL_INLINE
for compilers which can inline a function locally while at the
same time offering it for external linkage.
02-Sep-1998 (Lars Duening)
- (array.*) Commented and converted function defs to STD-C style.
- (array.c) Small improvements to unique_array() (boy, that code
is really old!).
- (main.c) Some warnings about unused variables prevented.
18-Aug-1998 (Lars Duening)
- (datatypes.h) New include file declaring all commonly used
datatypes of the virtual machine (svalue, vector, etc).
interpret.h keeps the interpreter related declarations only.
This also unclutters the struct svalue/smalloc.h relationship
a bit.
17-Aug-1998 (Lars Duening)
- (main.c) --options prints all the compilation options, --version
just the version. --help shortened to just list all commandline
options, --longhelp prints an elaborate description of these.
16-Aug-1998 (Lars Duening)
- (access_check.*) Commented, converted function defs to ansi style.
- The old access control using the ACCESS.DENY file is gone.
- (patchlevel.h) The GAME_VERSION define moved from config.h into here.
- (main.*) Commented, converted function defs to ansi style.
Rewrote the commandline argument parser. Most options are now
available in a short and long version; --version prints all
sorts of compilation options as well. New option --help.
- (driver/invocation) New documentation: driver invocation.
13-Aug-1998 (Lars Duening)
- Updated the hosts/*/config.h files.
- (hosts/be/be.h) The host dependent init makes sure that the erq
is not started automatically, even if the option to do so is
set in config.h
- (my-rusage.h) new, a wrapper for the rusage related stuff.
- (hosts/unix.h) received all the Unix specific portability
definitions from driver.h (this includes the cygnus win32
environment).
(port.h) received the remaining host dependent definitions, so that
(driver.h) can be dedicated to provide global definitions.
- (port.*, random.*) Commented, converted function defs to ansi style.
12-Aug-1998 (Lars Duening)
- (driver.h) Created from the old lint.h, it defines some macros and
includes config.h, machine.h and port.h. The system-dependent stuff
will move into port.h eventually. All sources changed to use
driver.h instead of lint.h.
- (my-alloca.h) new, a wrapper for <alloca.h>.
- (cruft/) New directory for code snippets which are no longer
useful, but interesting enough to keep around.
- (hosts/be/Makefile) New target 'dependall' updates the
dependencies in Makefile, Makefile.in, and the Makefiles
for Be, Amiga and OS/2.
11-Aug-1998 (Lars Duening)
- Compiled the sources with gcc on a high warning level and
removed as many warnings as possible. Added some patches
for compiling under Win32 with Cygwin32.
09-Aug-1998 (Lars Duening)
- 'Modularized' the sources: the exports of every .c file are
listed in an associated .h file, and only there. The liberal
sprinkling of 'extern' statements is gone.
10-Jul-1998 (Lars Duening)
- Release 3.2.1@141-osb.16
- (prolang.y) Fixed a pointer mixup which caused '"*"::' to end
in an endless loop. Bugfix provided by Daniel von Dincklage
(<vonDincklage@ozet.de> aka Sunblade@sd.mud.de)
- Updated the BeOS support: small tweaks to machine.h, the Makefile
now supports cross-compilation, a small hack in comm1.c.
04-Jul-1998 (Lars Duening)
- (prolang.y) In case of a 'Program too large' compilation error,
random memory was freed due to an uninitalized variable.
- (mudlib/test_master.c) Added this minimal master for simple
driver tests.
17-May-1998 (Lars Duening)
- Release 3.2.1@141-osb.14
- (interpret.c) The apply cache is initialized on driver startup, not
statically at compilation time. This allows compilers with less
capable preprocessors (line length limitations) to use big caches
as well.
16-May-1998 and before (Lars Duening)
- added rxcache.[ch]: cache for compiled regular expression patterns.
- added support for BeOS.
- (backend.c) Automatic garbage collections are kept at least 5 minutes
apart. Every garbage collection is logged on stdout.
- (backend.c) Variables are swapped independantly from program code.
- (comm1.c, main.c) Multiple login ports may be used in parallel. The
port numbers are given on the commandline, efun query_mud_port()
was extended to return the appropriate port number.
- (interpret.c) MudOS-efun terminal_colour() added by Mica.
- (interpret.c) this_object() in destructed objects does not print a
diagnostic anymore.
- (lex.c) more informative diagnostics about defbuf allocations. Too
big defbufs are deallocated again to conserve memory.
- (main.c) reallocation of system reserves prints diagnostics.
- (regexp.ch) NSUBEXP may take values different from 10 (OSB uses 50).
- (swap.c) Free space is reused immediately.
- (stralloc.ch, interpret.c) All the names of the lfuns applied by
the driver are stored in the shared string table on startup.
Together with some modifications to the apply cache for faster
processing of applys on shared strings, this should make a mud
a wee bit faster. Also added some comments in these areas (with
no guarantee for correctness!).
- (simulate.c) 'status tables' prints the number of cache hits both
absolute and as percentage.
