About this release...

I uploaded a "Release 3.2.6" on 31. March, but that was a premature action as later the same day I was informed that I managed to open a security hole. The fix was trivial, and so here it is: the real 3.2.6.

All this work couldn't been done without all my testers and critics who beared with me through the 30+ interim releases since 3.2.5.

Thank You!

History

01-Apr-1998 (Lars Duening) -- Release 3.2.6

• Changed efuns:
  • allocate_mapping() renamed to m_allocate().
  • clone_object() accepts objects as templates.
  • efun308() renamed to set_environment().
  • file_name() renamed to object_name().
  • filter_mapping() renamed to filter_indices().
  • mapping_contains() renamed to m_contains().
  • map_mapping() renamed to map_indices().
  • mapping_contains() renamed to m_contains().
  • m_values() can return any column of a mapping.
  • notify_fail() returns 0.
  • set_this_player() accepts 0 as argument.
  • to_int(), to_object() and to_float() accept their result type as argument.

  For all renamed efuns the old name is still available as alias.

• Corrected efuns:
  • call_out(): if the command_giver destructs before the callout is activated, this_player() is made sure to be 0.
  • map_array() stumbled when objects in the array in question were destructed during the operation.
  • sizeof(mapping) no longer counts destructed objects in the mapping to the size.
  • sprintf() of float values < 1.0 no longer causes a SING error.
  • terminal_colour() correctly wraps strings with a length one less than the wrap limit.
  • this_interactive(): during login it points to the login object.
• New efuns:
  • abs(): return the absolute value of the argument.
  • all_environment(): return all environments of an object.
  • caller_stack(): return the call stack.
  • clonep(): test if an object is a clone.
  • copy(): produce a shallow copy of the argument.
  • deep_copy(): produce a shallow copy of the argument.
  • filter(): filter an array or fill-width mapping.
  • load_name(): returns the filename of an objects blueprint.
  • load_object(): loads an object.
  • make_shared_string(): enters a string into the shared string table.
  • map(): map an array or full-width mapping.
  • m_reallocate(): changes the width of a mapping.
  • object_info(): returns internal information about an object.
  • program_name(): returns the name of an objects program.
  • set_next_reset(): set the time of the next reset.
  • unmkmapping(): deconstruct a mapping to arrays.
  • upper_case(): make a string all upper case.
  • widthof(): return the width of a mapping.
• Master Object:
  • All functions can be static.
  • Functions like privilege_violation() or heart_beat_error(), but also valid_read() and valid_write() no longer receive destructed objects as arguments.
  • Apply 'object_name()' renamed to 'printf_obj_name()'.
• Compiler:
  • New predefined macro __MAX_EVAL_COST__ expands to the evaluation cost limit.
  • Bugfix: __DOMAIN_NAME__ on some machines returned the NIS, not the DNS domain.
  • Bugfix: __MASTER_NAME__ could be set to a non-canonic name.
  • Bugfix: __FILE__ and __MASTER_NAME__ returned names with leading '/' in compat mode.
  • Bugfix: (virtual) inheritance of variable-only objects with variable initialisation doesn't crash the driver anymore.
  • Bugfix: #'++/#'-- in closures work.
• Fixed Crashers:
  • Errors in a callout to an efun closure.
  • Adding arrays up to and over the upper limit.
  • Destruction of non-interactive snoopers.
  • funcall()/apply() on a swapped variable.
• Other Changes:
  • The old behaviour of explode() and previous_object() is no longer available. Floats, transcendent functions, mappings and extended varargs are now permanent features of the driver.
  • Re-implemented the handling of heartbeats, resets, cleanups and swapping in order to avoid caused lags. This also makes the config parameter RESET_GRANULARITY unnecessary.
  • If used, the __INIT() function is protected instead of global, and can't be called from outside the objects anymore (it shouldn't be callable at all anyway).
  • When subtracting mappings from each other, the subtrahend may be of any width, but only its keys count.
  • The 'status tables' command has an additional entry 'Object status'.
  • Bugfix: fixed an eval cost leak in catch().
  • Bugfix: fixed memory leak in terminal_colour().
  • Bugfix: if a command disconnects, but not quits a player, the prompt is no longer printed (before it ended up on stdout, cluttering the logfiles).

10-Dec-1998 (Lars Duening) -- Release 3.2.5

• Collapsing of '/' in object names also used for inherits.
• Default limit for bitstrings is 6144 bits.
• The efuns break_point() and swap() are disabled by default.
• Pre-release versions have an extended version number of the form '3.2.5-dev.16'.
• 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__.
• New defines __ERQ_MAX_SEND__ and __ERQ_MAX_REPLY__ when the driver supports the ERQ. The values are the max sizes of the send and receive buffers (taken from x-erq by Brian Gerst).
• MSDOS support removed (the MSDOS filesystem however is still supported).
• It is now possible to use '..' in filenames as long as it doesn't has the 'parent directory' meaning (that means, 'foo..bar' is ok, bug 'foo/../bar' is not).
• When a connection is closed, the driver no longer sends 'Closing down' as last text.
• Bugfix: branches in bigger lambda() closures use the correct branch offsets. I am not completely sure if the bugfix is correct, so I left in two 'DEBUG:' diagnostics with information needed to debug the code further if necessary.
• Bugfix: the commandline parser printed a faulty error message if a required value was missing.
• Bugfix: mapping_contains() freed the wrong values, clobbering passed mapping literals.
• Bugfix: After an UDP packet was processed, the evaluation costs are restored (provided by Tucita).
• Bugfix: The LPC compiler now accepts only regular files for includes.
• Bugfix: If a npc was destructed between to command() calls, and the H_MODIFY_COMMAND hook was set to a string, the driver called the named modify-command function on the destructed npc.
• Bugfix: During the execution of a closure, an extra refcount is added to protect it from destruction while it is executed. This is primarily a safety measure for the driver hooks which only have 1 refcount and are thus very sensitive against master object updates.
• Bugfix: Under some OS like Linux, the normal SIG_IGN handler is just one-shot. To reliably ignore signals (ie SIGPIPE), a homemade handler is used.
• Bugfix: regreplace("acc", "a*", "yy",1) trashed memory.
• Bugfix: runtime errors in an alien-lfun-closure (as created by symbol_function() calls) no longer crash the driver during the error handling.
• Bugfix: sprintf() on big floats or in long fields no longer causes a buffer overrun (and should it happen nevertheless, a proper fatal() is generated).

24-Sep-1998 (Lars Duening) -- Release 3.2.4

• Bugfix for the collapsing of '/' in object names.

21-Sep-1998 (Lars Duening) -- Release 3.2.3

• Bugfix: mapping_contains() no longer returns destructed objects. (found by Zora).
• New special command 'status files' to append file usage statistics from within the mud to the file /FILESTAT.
• New commandline option: --swap-compact: reuse free space in the swapfile immediately. Giving this option results in smaller, but also more fragmented swapfiles, and the swap performance may degrade.

14-Sep-1998 (Lars Duening) -- Release 3.2.2

• Version number pattern changed from 03.02.1@<patchlevel> to 3.2.<patchlevel>. This affects all uses of the __VERSION__ lpc predefine.
• Objects may be loaded/inherited with filenames containing two or more consecutive '/'es, these are collapsed into just one. However, it is not possible to find objects using the wrong names. (suggested by Zora)
• The dreaded __INIT() bug is fixed (provided by mubo).
• New commandline options: --options : prints all options used in compiling the driver --version : prints the game driver version --help : prints a short help of the commandline options --longhelp: prints an elaborate description of the commandline options
• The commandline option handling was renovated, most options now exist in a short and long form. This caused slight changes in name and syntax for well-known options (.e.g '--gcollect_out_fd<file>' is now '--gcollect-out-fd <file>'). Please see doc/driver/invocation for further information.

10-Jul-1998 (Lars Duening) -- Release 3.2.1@141-osb.16

• Bugfix for the "*":: problem (provided by Daniel von Dincklage).
• Added a minimal master for simple driver tests.

17-May-1998 (Lars Duening) -- Release 3.2.1@141-osb.14 and before

• Small speedup for regexps through usage of a cache. Also increased the complexity limit for regexps.
• Added support for BeOS.
• Automatic garbage collections are kept at least 5 minutes apart. Every garbage collection is logged on stdout.
• Variables are swapped independantly from program code.
• 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.
• MudOS-efun terminal_colour() added by Mica.
• this_object() in destructed objects does not print a diagnostic anymore.
• 'status tables' prints the number of cache hits both absolute and as percentage.
