About this release...

• the interpret has been commented (that alone took several weeks)
• the configuration system was updated to use autoconf 2
• I added the old LP-2.4.5 mudlib as example mudlib to the distribution.

All this work couldn't been done without all my testers and critics who beared with me through the 60+ interim releases since 3.2.6.

Thank You!

History

19-Aug-1998 (Lars Duening) -- Release 3.2.7

• Changed efuns:
  • command():
    • native-mode restriction to the current object is gone since there is no native mode anymore.
    • commands are now stacked, meaning that after a command finishes, the previous this_player(), verb, etc, are restored.
  • debug_info():
    • debug_info(DINFO_STATUS): now returns the status information instead of printing it. debug_info(DINFO_STATUS, "malloc") returns the malloc information usually connected with the 'malloc' command.
    • debug_info(DINFO_DUMP): allows to dump object information and (if compiled) opcode usage information into a file.
  • destruct(): accepts an already destructed object as argument.
  • get_type_info(): returns for strings whether they are shared or not.
  • inherit_list(), debug_info(), object_info(): duplicate virtual inherits are no longer listed.
  • notify_fail(): calls to notify_fail() only affect the current command. Also, NPCs can see 'their' notify_fail messages.
  • object_info(): OINFO_BASIC result OIB_APPROVED is gone.
  • replace_program(): no longer flags objects as 'clones', but instead uses the new flag O_REPLACED.
  • set_light(): is optional (though by default active)
  • sprintf(), printf(): if an error occurs, the filename and line are included in all error messages, not just the one printed to stderr.
  • symbol_function(): can't make closures from protected lfuns of other objects anymore.
  • trace(), traceprefix() are validated with the master-lfun valid_trace().
• Corrected efuns:
  • caller_stack(): is now declared to return object * as it indeed does.
  • query_mud_port(): now accepts int arguments as documented.
  • restore_object(): protected against negative ([:width]) specifications.
  • sprintf()/printf(): prints variable closures properly even if the variable vanished in a program replacement.
  • symbol_variable(): recognizes objects with pending program replacements.
  • terminal_colour(): when wrapping is active, keywords were replaced even when no %^ was present. Not any more.
  • to_object(): returns 0 for closures bound to a destructed object.
  • to_string(): converts variable closures properly even if the variable vanished in a program replacement.
  • to_string(): in compat mode, object names are no longer prepended with a slash.
  • unmkmapping(): now handles key-only mappings as it should.
• New efuns:
  • atan2(): alternative way to calculate the inverse tangens.
  • ceil(): rounds a float up to the nearest whole number.
  • floor(): rounds a float down to the nearest whole number.
  • pow(): raises a float to the power of another float.
  • and_bits(): binary-ands two bitstrings.
  • or_bits(): binary-ors two bitstrings.
  • xor_bits(): binary-xors two bitstrings.
  • invert_bits(): negates a bitstring.
  • next_bit(): finds the next set (cleared) bit in a bitstring.
  • last_bit(): returns the last set bit in a bitstring.
  • count_bits(): count the number of bits in a bitstring.
  • (preliminary) command_stack(): returns the current command stack.
  • command_stack_depth(): returns the depth of the command stack.
  • (preliminary) execute_command(): low-level access to the command parser.
  • query_command(): returns the full command seen by the parser.
  • query_notify_fail(): returns the current notify-fail setting.
  • object_time(): return the time an object was created.
  • (preliminary) present_clone(): find objects with a specific blueprint in a given environment.
  • trim(): trim a certain character from a string.
  • (preliminary) limited(): executes a closure with changed runtime limits
  • query_limits(): queries the current/default runtime limits
  • (preliminary) set_limits(): sets new default runtime limits.
• Master Object:
  • valid_write(): New call_funs "objdump" and "opcdump", passed when attempting to dump the object and opcode information into a file. This applies to the special commands dumpallobj and opcdump as well as for the debug_info() uses.
  • query_player_level(): obsolete and gone.
  • valid_trace(): New lfun to validate uses of trace() and traceprefix() (query_player_level() did this before).
• Fixed Crashers:
  • A heart_beat() removing all remaining objects on the hb list.
  • An error during a (s)efun bound to a swapped out object could crash the dump_trace.
  • An error during macro expansion crashed the driver if the error handling itself required macro expansion again.
  • to_string() on a lfun of a swapped program.
  • call_lambda() on not-inherited variable closures.
  • replace_program() on a program of which one variable is referenced by a symbol_variable().
  • Swap in of a closure variable which was invalidated during a garbage collection.
  • Failure to swap in an object during a garbage collection.
  • Binding an unbound lambda to two objects and destructing the originating object freed the lambda.
• Language:
  • += now allows to add an int onto a float (before only floats were allowed). Similar for -=, *= and /=.
  • * and *= may multiply strings or arrays with positive numbers. The result is the string/array numbertimes repeated.
  • Scope of variables defined in nested local blocks ends with the defining local block. The limit MAX_LOCAL applies only to the variables which are in scope at the same time. Variables in inner scopes can hide variables in outer scopes. Unchanged is that local variables are initialised to 0 when their scope is (re)entered.
  • The pragmas no_local_scopes and local_scopes turn the local scoping of variables off resp. back on.
  • in for(init, init, ..., init; ...) each init can either be a normal expression, or a definition of a local variable with assignment, e.g. int i = expr. The scope of such variables is the whole for() statement.
  • added inline closures as alternative to lfun closures: instead of
     int foo(int arg ) { return arg * 2; }
 map_array(arr, #'foo);
    you can write
     map_array(arr, (: return $1 * 2; :) );
    or just
     map_array(arr, (: $1 * 2 :) );
    The syntax is modelled after MudOS functionals.
  • Support for alien-lfun closures was incomplete.
  • New pragma no_clone: disallows clones of a program.
  • New pragma no_inherit: disallows inheriting a program.
  • Bugfix: Variables in closures may start with '_'.
  • Bugfix: *::f() did not call all inherited functions (and others multiple times).
  • Bugfix: '#[<] indexing corrected.
• Runtime:
  • If hook H_RESET is a closure, and the closure returns a negative value, the object will not be reset again, as if set_next_reset(-1) had been used.
  • New optional driver hook H_COMMAND allows to replace the driver command parsing with your own. When used, the H_MODIFY_COMMAND and H_NOTIFY_FAIL hooks are ignored.
  • The H_MODIFY_COMMAND hooks may now change the commandgiver. The change remains active during the execution of the command, and the original commandgiver is passed to the NOTIFY_FAIL hook.
  • Mappings have an upper limit of MAX_MAPPING_SIZE keys (default is 5000).
  • Special commands dumpallobj and opcdump are verified through master->valid_write().
  • Driver can be compiled for DYNAMIC_COSTS, causing increased eval-costs for computationally expensive operations. For now, this applies only to string additions with an additional cost of strlen(result)/1000 .
• Other Changes:
  • Tweaks to the timing of swapping, cleanup() and reset() to achieve a smoother operation.
  • On loading errors, the name of the affected object is printed in the error message.
  • The multiport feature is no longer optional.
  • Corrections to the manpages of clone_object, clonep, filter_mapping, filter_indices.
  • Added the include files mudlib/sys/{trace.h,input_to.h,files.h, debug_info.h} with definitions for the efuns trace(), input_to(), file_size(), get_dir(), and debug_info().
  • NATIVE_MODE is gone.
  • Euids are now a standard feature (the LPC macro __EUIDS__ stays defined, though).
  • Use of euids (loading or cloning other objects requires a non-zero euid) can be enforced with the commandline option --strict-euids. If defined, the LPC macro __STRICT_EUIDS__ is defined. If your mud ran in NATIVE_MODE, this is the option you'll want to use.
  • The commandline options --reset-time and --cleanup-time specify the cleanup and reset times. The old config.h symbols TIME_TO_RESET and TIME_TO_CLEAN_UP just give the default values.
  • The commandline options --max-array and --max-mapping can set the max limits for arrays and mappings. For both, a setting of 0 disables the limit checks.
  • The commandline options --max-bytes and --max-file can set the max IO limits for file reads and writes.
  • Efun closures are printed with full name in error tracebacks.
  • The ACCESS.ALLOW file can specify portnumbers.
  • Special command status malloc is now identical to malloc.
  • Special commands debugmalloc and showsmallnewmalloced are deactivated.
  • Bugfix: Reset of swapped objects did not work properly.
  • Bugfix: Errors during the execution of closures no longer leak memory.
  • Bugfix: Switching driver hooks from within themselves no longer leaks memory.
  • Bugfix: New callouts added from within a callout with odd delay resulted in the new callouts called at the wrong time. If the new callout had a MAX_INT delay, the existing callout list was effectively disabled.
