LDMud 3.3 (stable)

This is the stable version of LDMud.

Summary of Changes in 3.3.720

Fixed Crashes
xml_generate(), xml_parse() could crash the driver due to a wrong order during initialization of libxml2 (#671) and could lead to memory corruption, because the memory used by libxml2 was subject to the garbage collector and would be free'd by it while still in use.
xml_generate(), xml_parse() could also crash the driver due to a wrong order during cleaning up, where a buffer could be freed prematurely.
get_type_info() lost refcounts to the function name of a closure, causing it eventually being free'd prematurely (#712).
'dumpallobj' crashed if there are strings with 0 refcounts (#725).
fixed a crash during tracing caused by a wrong call to add_message() in do_trace(), when compiled with --enable-debug (#736).
Entering destructed objects as keys into a mapping could crash the driver later on.
Very long function names with symbol_function() could crash the driver due to a corrupted stack.
exec() when the player's socket buffer was full crashed.
Destroying objects during initialisation, process_string() or transfer() could crash the driver.
Changed Efuns:
- get_dir():prepend '/' in plain mode for entries in the root directory, if paths are requested by GETDIR_PATH.
- tail():marked as deprecated (#228)
- sort_array() will sort in-place instead of a copying the array first, if the array is passed as reference. (#224)
- to_struct() can convert a struct into another one if one of them is a (indirect) base of the other. (#646)
- clone_object() does not deactivate an active heart_beat in a blueprint. (#747)
- Fixed result of convert_charset():returns now the unchanged string if it gets an empty string for conversion. (#739)
- Runtime
- A base struct is recorded as base struct in a child struct even if the base struct has no members. (#695)
- Improved the determination of the drivers current_time which fixes issues with wrongly timed heart_beats or apparantly wrong timings. (e.g. #743)
- Migrated from signal() to sigaction() and alarm() to setitimer() to set the alarm and its handler, which seems to fix some issue with lost alarm signals. (#607)
- Host system time and mud-internal time are now better synchronized.
- Language
- A new modifier 'deprecated' can be used to mark lfuns, sefuns and global variable as deprecated. Using/Calling them will cause warnings. (#749)
- Networking
- UDP datagrams with lengths up to 65507 (including UDP and IPv4 headers: 65535) bytes are supported.
- SSLv2 connections are rejected, since they are insecure and long obsolete.
- Some reasons for SSL disconnects were removed. (#737)
- Configuration option tls_trustdirectory is deactivated by default.
- All unknown telnet options are now passed to the H_TELNET_NEG hook. (#670)

Summary of Changes in 3.3.719

Fixed Crashes:
- gmtime(), localtime(), ctime() and strftime() could crash the driver on platforms where time_t is 64 bits long and users supply huge values as time stamp (>2^55) due to unchecked results from libc functions (Bug #587).
- 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)
New Efuns:
- configure_interactive():To set options for interactives.
- configure_driver():To set settings/options for the driver itself.
Changed Efuns:
- idna_stringprep():fixed the evaluation of the arguments and removed a memory leak (#498).
- map():it's now possible to specify a mapping column when mapping through mappings (#367)
- tls_check_certificate(), tls_refresh_certs():Now available if GnuTLS is supported.
- hash() and hmac() is now always available und is able to use OpenSSL, libgcrypt or internal MD5 and SHA1 routines (builtin routines for hash() only). hash() costs 10 ticks per iteration.
- md5() and sha1() are obsoleted by hash().
- lambda() now supports bound and unbound lambdas as the first element in an array of a lambda expression.
- xml_generate(), xml_parse():Also available using libxml2.
- cat():marked as deprecated (#637)
- Runtime
- The --max-malloced memory limit was renamed to --hard-malloc-limit.
- Introduced new --soft-malloc-limit in addition to the hard one.
- When exceeding the soft memory limit, the function low_memory() is called in the mudlib master with details about the kind of low memory situation. This check is done during the backend cycle and not at 'real-time'.
- Made the maximum length of commands configurable at compile-time (MAX_COMMAND_LENGTH, --max-command-length)
- The driver hook H_MSG_DISCARDED can be used to specify the messages given to players when their messages were discarded.
- The soft and hard memory limits can now be configured at runtime (configure_driver()).
- Language
- Added a permanent define __MAX_COMMAND_LENGTH__ for the maximum length of command.
- Added a permanent define __GCRYPT__ when libgcrypt support is available.
- Portability
- 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.)
- Fixed a major bug on 64 bit platforms, where floats with negative exponents were saved incorrectly leading to data corruption (#627).
- 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 checks and special code 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
- Removed checks and special code for Ultrix.
- Removed MSDOS filesystem semantics (Checks for MSDOS_FS and special behaviour (e.g. \\ as path separator).
- Support for using mmap() to get memory from the system (slaballoc), because brk()/sbrk() are more or less deprecated and not supported by some systems (e.g. Darwin/MacOS). (#640)
- Support for using mmap() to get memory from the system (smalloc). (#640)
- Other
- Generalized the write buffer for non-threaded use and renamed the configuration option '--with-pthreads-write-max-size' to '--with-write-buffer-max-size'.
- Removed background threads that sent the data to the network and with it the '--enable-use-pthreads' configuration option.
- The commandline options '--access-file' and '--access-log' specify the access permissions and log file, activating or deactivating access control and log. The old configure options '--enable-access-control', '--with-access-file', '--with-access-log' and their config.h symbols ACCESS_FILE and ACCESS_LOG just give the default values.
- The default path of TLS certificates are now configurable during compile time (--with-tls-keyfile, --with-tls-certfile, --with-tls-trustfile, --with-tls-trustdirectory, --with-tls-crlfile, --with-tls-crldirectory), these TLS features can also be deactivated by giving "no" during compile time or "none" as a runtime parameter.
- Ed sessions are removed when an object becomes non-interactive.
- Multiple ed sessions per interactive are allowed.
- Check the compiler for support of -fwrapv and enable if supported. Enables a fully defined overflow/wrap behaviour of signed integers (#635)).

Summary of Changes in 3.3.718

Changed Efuns:
- md5():The efuns costs 10 eval ticks per iteration (Bug #485).
- sha1():The efuns costs 10 eval ticks per iteration (Bug #485).
- strrstr():A starting position of the input string's length led to the target string never being found (Bug #509).
Compiler:
- After two consecutive inline closures within the same function, the line number information was incorrect (Bug #510).
- Corrected an off-by-one linenumber error related to auto-include strings (Bug #508)
Other:
- Improved the removal of actions added by shadows (Bug #514).

Summary of Changes in 3.3.717

Changed Efuns:
- md5():The efuns costs 10 eval ticks per iteration (Bug #485).
- sha1():The efuns costs 10 eval ticks per iteration (Bug #485).
- strrstr():A starting position of the input string's length led to the target string never being found (Bug #509).
Compiler:
- After two consecutive inline closures within the same function, the line number information was incorrect (Bug #510).
- Corrected an off-by-one linenumber error related to auto-include strings (Bug #508)
Other:
- Improved the removal of actions added by shadows (Bug #514).

Summary of Changes in 3.3.716

Changed Efuns:
- load_object():The object name must not be empty (Bug #500).
Fixed Crashers:
- Size-changing mapping operations didn't fully check for destructed objects as keys, sometimes derefencing invalid pointers in the process (Bug #517).
- Removed a crasher when running with --check-refcounts: References by snooping non-interactives weren't counted (Bug #492).
- Loading an object with an empty name twice could crash the driver (Bug #500).
- clone_object():When initializing a clone's variables using #pragma share_variables, really use the variables from the blueprint object being given. This allows the handling of inherited blueprint objects with replaced programs. (Bug #483)
- An argument mismatch error during a lfun-closure call could crash the driver. (Bug #495).
- The definition 'struct abc abc;' could crash the driver. (Bug #494)
- The use of local undefined structs as struct abc abc = (<abc>) could crash the driver. (Bug #493)
Compiler:
- The lfuns backing the inline closures are again 'private nomask'.
Runtime:
- foreach(int i: num) recognizes if num is negative and throws an error. (Bug #503)
- The handling of charmode with combine-charset could lead to premature socket closing if present with longer data than the input buffer could at one time. (Bug #442)
- The Apply-Cache statistics counters should overflow less often (Bug #520).
- If a simul_efun object appears before being 'blessed', that object is rejected to avoid variable/function inconsistency bugs. (Bug #489).
Other:
- The autoconfiguration of YACC was incompatible with gentoo Linux.
- Removed a few (partly fatal) 64-bit issues (Bug #490, #491).
- Removed a memory leak when catching errors inside master::runtime_error() (Bug #513).

Summary of Changes in 3.3.715

New efuns:
- tls_refresh_certs(): Reload the certificates and certificate revocation information.
Other Changes:
- New commandline options to handle certification revocations: --tls-crlfile and --tls-crldirectory.

Changelog

22-Feb-2011 (LDMud Team) 3.3.720

Created snapshot. 2011-02-22 (Gnomi)
Added checks for destroyed objects in clone_object(), process_string() and transfer(). (fixes #772) (simulate.c, efuns.c, object.c) 2011-02-19 (Zesstra)
Check 'deprecated' modifier for global variables. In addition to functions the compiler and symbol_variable() check if a global variable is deprecated and issue a warning. Local variables are not checked. (closure.c, prolang.y, interpret.c, prolang.y) 2011-02-19 (Zesstra)
Added check for 'deprecated' for lfun closures. Added a check for deprecated lfuns upon creation of closures by #'fun or #'::fun (compile-time). (lex.c, prolang.c) 2011-02-19 (Zesstra)
New modifier 'deprecated' for lfuns. Functions can be marked with 'deprecated', which causes a warning when they are called. Intra-object calls will cause compile-time warnings, inter-objects calls (callother, lfun closure calls) compile-time warnings. (prolang.y, lex.c, interpret.c, closure.c) 2011-02-19 (Zesstra)
Added testcases for some basic operators dealing with ints. Added some testcases for bitwise AND, OR, XOR, left shift, right shift, logical right shift, modulus and their respective assignment operators. 2011-02-19 (Zesstra)
pkg-gnutls: added some attributes for nonnull pointer arguments. Some functions should never get NULL pointers as args. Marked these args as 'nonnull'. (pkg-gnutls.c) 2011-02-19 (Zesstra)
pkg-gnutls:tls_write(): added comment about retries. GnuTLS and OpenSSL require a specific behaviour in case of interupted or blocking sockets. This adds a comment about the specifics of GnuTLS. (pkg-gnutls.c) 2011-02-19 (Zesstra)
pkg-gnutls:tls_read(): let caller retry reading later. If the internal retry counter in tls_read() is not sufficient and the error is still GNUTLS_E_INTERRUPTED or GNUTLS_E_AGAIN return EINTR or EWOULDBLOCK to get_message() which will try again later. (bug #737) (pkg-gnutls.c) 2011-02-19 (Zesstra)
comm_send_buf(): Removed dead code. Removed code that was never executed. Additionally, don't increment the inet_packets counter if nothing was sent. (comm.c) 2011-02-19 (Zesstra)
Added some function attributes and assert(). Some functions should never get NULL pointers as args. Lengths of 0 in SSL_write() lead to undefined behaviour. Should never happen and will be asserted now. (pkg-openssl.c) 2011-02-19 (Zesstra)
Simplified error handling in tls_read/tls_write(). Combined cases for err==0 and err<0 into one if block. (bug #737) (pkg-openssl.c) 2011-02-19 (Zesstra)
Dump error stack to debug logs on disconnects. If compiled with DEBUG, the OpenSSL error stack will be dumped into the debug log on disconnects in tls_read()/tls_write(). May help finding the reasons for disconnects. (bug #737) (pkg-openssl.c) 2011-02-19 (Zesstra)
Simplified error handling in get_message(). Converted a bunch of if() into a switch and use strerror() to ouput meaningful error messages in the default case (bug #737). (comm.c) 2011-02-19 (Zesstra)
Removed some disconnects in case of recoverable errors. Sockets reads might be interupted by signals and return EINTR. In this case it will just be retried later again. tls_read() may stumble upon SSL_ERROR_WANT_READ/_WRITE. In these cases it now sets errno to EAGAIN instead of disconnecting the user. It also keeps the connection in case of SSL_ERROR_SYSCALL if errno is EAGAIN or EINTR (bug #737) (comm.c, pkg-openssl.c) 2011-02-19 (Zesstra)
Set SSL_MODE_RELEASE_BUFFERS in SSL context. The flag configures OpenSSL to release unused buffers in idle SSL connections. (pkg-openssl.c) 2011-02-19 (Zesstra)
Disallow SSLv2 connections. SSLv2 is long deprecated and should not be used anymore. (pkg-openssl.c) 2011-01-25 (Gnomi)
Explicit context variables overwrote the types of the closure's arguments. (fixes #711) (prolang.y) 2011-01-25 (Gnomi)
optpat() shouldn't read over the end of the given ed command. (fixes #722) (ed.c) 2011-01-11 (Zesstra)
Add some fresh entropy to the PRNG from time to time. Everytime a new TLS connection is initialized, the current time (gettimeofday) is added to the entropy pool of OpenSSL. Additionally, for the next new connection after PRNG_RESEED_PERIOD/2 + random(PRNG_RESEED_PERIOD) seconds RAND_poll() from OpenSSL is called to add fresh entropy from a stronger source of entropy. (pkg-openssl.c) 2011-01-11 (Zesstra)
Do not seed the OpenSSL PRNG with little entropy (#678) We used to seed OpenSSL's PRNG by using very weak sources of entropy. On system without a strong source of entropy (/dev/urandom, EGD etc.) this could lead to false sense of security. By not seeding ourselves, we force TLS to fail completely, if OpenSSL can't get enough entropy automagically. 2011-01-09 (Zesstra)
Removed an error from varargs manpage (fixes #767). 2011-01-08 (Zesstra)
_expand_define(): skip only leading/trailing whitespace. Commit 05202ac2b5789057de7f6d24e43fb59e969b4c12 skipped also the whitespace within the arguments, which has to be preserved. This commit changes the behaviour to only skip leading and trailing whitespace in the macro arguments. (fixes #729) (lex.c) 2011-01-06 (Zesstra)
Fixed manpage of call_out. The manpage incorrectly stated a minimum delay of 1 second and mentioned rounding up to the next multiple of __ALARM_TIME__. Additionally added a comment about the real delay being between delay and delay+__ALARM_TIME__. 2011-01-06 (Zesstra)
Rename IncCmdGiver to DecreaseCmdGiver. This define suggests to increment something, but it decrements. (comm.c) 2011-01-06 (Zesstra)
_expand_define(): skip whitelist in argument list (fixes #729) _expand_define() skipped whitespace only at the start of the argument list, but not in between or trailing whitespace which lead to unexpected behaviour in case of #define quote(X) "X". (lex.c) 2011-01-05 (Zesstra)
Set SSL_MODE_ACCEPT_MOVING_WRITE_BUFFER in SSL context. SSL_write() of OpenSSL requires to be called with the same arguments for a retry after SSL_WANT_READ/SSL_WANT_WRITE. With this flag, it also accepts a different buffer as long as its content is the same. Should solve some SSL/TLS disconnects (bug #737) (pkg-openssl.c) 2010-11-17 (Zesstra)
Typo fix in m_contains manpage (fixes #761). 2010-11-17 (Zesstra)
Corrected example for regreplace usage (fixes #760). 2010-07-15 (Zesstra)
Check refcounter before division in svalue_size(). Reference counters are all checked to be != 0 before divisions, because the counters might overflow to 0 and might be constantly 0 from then on because reference counting is disabled for that entity. (dumpstat.c) 2010-07-14 (Zesstra)
Changed signal handling in comm to sigaction(). Use sigaction() in comm.c as well. Removed the signal handler for SIGPIPE and ignore the signal (our old handler ignored it as well). (comm.c) 2010-07-14 (Zesstra)
Synchronize the alarm timer to full seconds. As the mud internal time is only updated each alarm time this resulted in up to (alarm_time+1) seconds delay between the two. When the first timer is set up, we now take care to expire it on a full second to improve synchronicity (to a max. difference of (alarm_time)s). (backend.c) 2010-07-14 (Zesstra)
Changed from alarm() to setitimer(ITIMER_REAL,) The alarm had to be (re-)set every time after an alarm occurred and if an alarm was missed somehow, this could lead to switched off alarms (main reason for check_alarm). We now use setitimer(ITIMER_REAL,...) to set a recurring realtime alarm, which simplifies matters and should make the check_alarm() obsolete. (backend.c) 2010-07-14 (Zesstra)
Use sigaction for installing signal handlers. Because signal() can not be used in portable way to install signal handlers but sigaction() can, the driver installs the handlers now with sigaction(). Another advantage is, that the handler don't have to re-install themselves. (main.c, backend.c) 2010-06-03 (Zesstra)
Added note about host system dependency for convert_charset(). The capabilities of convert_charset() depend on the libiconv of the host system. The manpage now has a hint about this. 2010-05-12 (Gnomi)
Corrected the call to mysql_options. Use the generic error message when mysql returned an empty one. (pkg-mysql.c) 2010-05-04 (Fuchur)
Enable automatic reconnects on MySQL database handles. (#750) 2010-05-01 (Zesstra)
Updated settings for Avalon. 2010-04-26 (Zesstra)
Fixed result of convert_charset(). If convert_charset() got an empty string for conversion, it returned its 3rd argument (to-charset). It now returns the unchanged string. (#739) (strfuns.c) 2010-04-26 (Zesstra)
Don't deactivate a blueprints heartbeart upon cloning. The blueprints HB were supposedly deactivated upon cloning to prevent copying the active HB state to the new object. But since this anyway does not happen and clone_object() should not deactivate the blueprints HB permanently, this deactivation was removed (#747). (simulate.c) 2010-04-21 (Zesstra)
Changed mk-patchlevel to create correct revision data. mk-patchlevel uses information from version.sh to add version and revision information to patchlevel.h. Unfortunately, version.sh seems to be updated by some unknown release script and contains horribly outdated information. mk-patchlevel tries now to extract the current revision from either SVN or git first and then tries version.sh. 2010-04-21 (Zesstra)
Fixed manpages of load_name concerning VC objects. load_name() returns the original loadname of the object created by the VC. 2010-03-16 (Zesstra)
Removed indefinite retries in tls_write(). tls_write() had no retry counter and retried for as long as the error was SSL_ERROR_WANT_READ/_WRITE. Similar to pkg-gnutls.c we just set errno to EWOULDBLOCK and let the caller handle the retries. (pkg-openssl.c) 2010-03-16 (Zesstra)
Fixed return value of tls_read/tls_write(). A wrong usage of the variable ret could in some error conditions lead to a wrong return value and return a positive number of bytes read/written where nothing was read/written. (pkg-openssl.c) 2010-03-11 (Zesstra)
Fixed add_message() call in do_trace(). do_trace() called add_message("%s",message_flush), which should be add_message(message_flush); Otherwise add_message() calls strlen() with the NULL pointer, leading to crashes (#736). (interpret.c) 2010-02-13 (Zesstra)
Fixed Div-by-Zero in svalue_size(). svalue_size() divides the memory used for a string by its refcount, but 0 refs are valid for strings. This leads to a crash in then wiz command 'dumpallobj', unless the refcount is checked before division. (#725). (dumpstat.c) 2010-01-31 (Zesstra)
Increased UDP receive buffer, because UDP datagrams can be much larger than 1024 bytes and the rest of the datagram would be discarded upon recvfrom(). Datagram lengths up to 65507 bytes (including UDP and IPv4 headers: 65535) are supported now. (comm.c)
Removed dirty BeOS hack. (comm.c) 2010-01-24 (Zesstra)
get_type_info() failed to reference the function name it returns, causing the string to loose refcounts and being eventually free'd erronenously. (#712) (efuns.c)
Removed a potential double free in struct_new_anonymous(). (structs.c)
Record a base struct as base struct in a child struct even if the base struct has no members. (#695) (prolang.y)
to_struct() converts a given struct into a struct with the same type as the template struct given as optional second argument. (#646) This conversion is only done if the template struct is a base of the given struct or vice versa. Otherwise an error is raised. (efuns.c)
Renamed baseof() to struct_baseof(). (structs.c, interpret.c, efuns.c)
Use shrink_array() only for alists. Intersecting empty arrays or mappings references the null_vector instead of creating a new empty array with shrink_array(vec,0). shrink_array is only used in intersect_ordered_arr(). (array.c, mapping.c)

22-Dec-2009 (Gnomi)

When removing unnecessary F_SAVE_ARG_FRAMEs the compiler didn't adjust last_expression correctly in same cases leading to false program optimizations. (#683, #708, #709) (prolang.y)

10-Nov-2009 (Gnomi)

Check for references to destructed objects before entering them as keys into a mapping. (#689) (mapping.c)
Pass all unknown telnet options to the mudlib. (#670) (comm.c)
Let the player_for_flush list point to interactive_t* directly. This avoids inconsistencies between objects and their interactive structure caused when exec()ing. (Bug #683) (comm.c)

22-Oct-2009 (Zesstra)

sort_array(): sort in-place if array is given as reference. (#224) (array.c, func_spec)

21-Oct-2009 (Zesstra)

Applied a bunch of small fixes for manpages by Coogan. (#692)
Marked tail as deprecated, added sefun tail(), updated documentation of tail(). (#228)

18-Oct-2009 (Gnomi)

Free the xml buffer after xml reader and writer, because they might use it when cleaning up. (maybe #683) (pkg-xml2.c)
Don't call xmlCleanupParser, as it should be called when there's no more xml processing. Don't call xmlInitParser, as it is already done on startup. (pkg-xml2.c)

13-Oct-2009 (Gnomi)

Deactivate tls_trustdirectory per default as /etc/ssl/certs may contain a large number of certificates on usual installations (which are not related to client certificates) and GnuTLS clients have a problem with that (too large handshake data). Whoever wants to use client certificates shall set it up explicitely. (configure)
Updated Avalon settings file. (settings/avalon)

05-Oct-2009 (Zesstra)

prepend '/' in get_dir() in plain mode for entries in the root directory, if paths are requested by GETDIR_PATH. They were omitted until now. (#501) (files.c)

04-Oct-2009 (Zesstra)

Use CRYPTO_set_mem_functions() to register function pointers to our own allocator functions in openssl. (pkg-openssl.c)

16-Sep-2009 (Zesstra)

'status/malloc' commands include now the allocator in use (Patch from Xtian, #672) (slaballoc.c, xptmalloc.c, smalloc.c) 12-Sep 2009 (Fuchur)
fix some refcounting issues (interpret.c) 08-Sep 2009 (Zesstra)
Get permanently allocated memory in xml_pkg_strdup(), which is not subject to the GC to prevent some nasty problems. (pkg-xml2.c)

04-Sep-2009 (Zesstra)

Fixed initialization of libxml2 (#671). LIBXML_TEST_VERSION already allocates memory, so xmlMemSetup() has to be called before that macro. Otherwise crashes may occur. (pkg-xml2.c)
Use the 'permanent' variants of our allocation function, because the memory used by libxml2 should not be subject to the garbage collector. (pkg-xml2.c, pkg-iksemel.c)

01-Sep-2009 (Gnomi)

Fixed a crash in symbol_function with very long function names by removing the necessity of an alloca and giving make_shared_identifier the length of the identifier as an additional parameter. (lex.c, prolang.y)

03-Aug-2009 (Gnomi)

Memory corruption when using protected string ranges. (interpret.c)

20-Jul-2009 (Gnomi)

Set a maximum number of retries for reading data (in case the underlying functions go crazy and cause an endless loop). (pkg-gnutls.c, pkg-openssl.c)

23-Jun-2009 (Gnomi)

Corrected a memory leak in send_udp. (comm.c)
String corruption by present_clone. (efuns.c)

15-Jun-2009 (Fuchur)

(parse.c) Fix off-by-one error in find_string(). It returned a wrong index.

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().

(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

Fixed german manpage for unique_array() which contained german and english.

30-Jan-2009 (Fuchur)

(main.c) Fix bug building erq_args, which could cause memory corruption. (#604)

29-Jan-2009 (Gnomi)

(access_check.c, comm.c, main.c) Made access control a runtime option.

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)

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)

(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.

(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.

16-Jan-2009 (Zesstra)

(config.h.in, lex.c) Enforce the possible value range for ITABLE_SIZE (256

12-Jan-2009 (Lars Duening) 3.3.718

Created snapshot.

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 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.

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.
