CHANGES.TINY20

This is the NOTES file for TinyMUX version 1.0, detailing the patches to
TinyMUSH 2.0 to the 2.0.10 patchlevel 6, on which TinyMUX is based.

TinyMUSH 2.0 patchlevel 1:

- Replaced the dynahash database layer with Marcus Ranum's untermud
  database layer.  This fixes the 'attribute-eating' bug (aka the 'nothing'
  bug.)
- New switches to commands:
    @clone: /inherit /preserve.
- New commands: SESSION @last.
- New functions: AFTER BEFORE ROOM REVERSE REVWORDS.
- Last successful connect displayed when you log in.
- Notice of any failed connects when you log in.
- Players with the BUILDER flag set are no longer sent home when their
  container teleports.
- Corrected a problem with wizards @destroying exits in another room.
- @dolist now runs the commands in the intuitive order.
- examine and @edit now support wildcard attribute names.
- @lock/unlock <obj>/<attr> only affects the locked flag of the attribute.
- @set <obj>/<attr> = [!]no_command now sets/clears the no_command flag on an
  attribute.
- You may overwrite/clear unlocked attributes owned by others on your objects.
- Locked attributes may not be changed at all.
- TinyMUD database files up to version 1.5.5 may be read in.

TinyMUSH 2.0 patchlevel 2a:

- Players and things may now have exits from them.
- @clone can now clone rooms and things.
- @decompile can decompile any object type.
- New locks (set by switches to @lock and @unlock commands):
    drop enter give leave page receive tport use
- Owned-by lock qualifier (matches anything owned by the owner of the object)
- Enter/leave aliases.
- You can get and drop exits.
- If the home or dropto of an object/room is destroyed, the home or dropto 
  is reset before the object is re-allocated.
- New functions: MAX MIN
- New switches to commands:
    @open: /inventory /location
    @clone: /inventory /location
- New attributes:
    @away @idle @reject: Page-return messages.
    @ealias @lalias: Enter aliases and leave aliases.
    @alias: An alternate name for a player (for paging, *-lookup, etc)
    @efail/@oefail/@aefail: for when you fail to ENTER somewhere.
    @lfail/@olfail/@alfail: for when you fail to LEAVE somewhere.
    @tport/@otport/@oxtport/@atport: for when you @teleport.
    Lastsite: the host from which you last logged in.
- You no longer get 'has left' and 'has arrived' when you drop or pick up
  hearing objects.  Others in the room (or in your inventory) still see them.
- You now always get the 'You get your xx penny deposit...' message when one
  of your objects is destroyed - even if it was automatically destroyed
  (say because it was an exit that was in a destroyed room).
- All objects that enter or look around in a location trigger the adesc and
  (if a room) asucc attributes.
- Whispering to faraway players (ala @pemitting to faraway players) is no
  longer allowed for nonnwizards.
- The HAVEN flag no longer blocks pages.  Use the new page lock for that.
- Fixed a couple of memory leaks.
- @decompile now takes a 'target name' and produces code to set attributes on
  the named target (if specified).

TinyMUSH 2.0 patchlevel 2b:

- New functions: SEARCH STATS.
- New flags: SAFE MONITOR.
- New switches to commands:
    @destroy: /override
- If you put a space after the colon in a colon-pose command (ie ': test'),
  then the space between your name and the message will be omitted.
  This makes ': test' equivalent to ';test'.
- Fixed a money leak in the @halt command.

TinyMUSH 2.0 patchlevel 2c:

- New functions: GET_EVAL ITER.
- Multiple @listens: Attributes of the form ^<pattern>:<commands> are checked

  matches, the commands are executed.

TinyMUSH 2.0 patchlevel 3:

- New functions: EDIT LOCATE SPACE SWITCH U.

- New attributes: @filter @infilter @inprefix @prefix.
- New locks: linklock teloutlock.
- Non-hearing objects no longer trigger adesc/asucc when they enter or look
  around in a location.  (Non-hearing objects looking is pointless).
- SESSION now displays user port number (really the internal file_id number)
- When invoked by wizards, WHO displays the player flags DARK, UNFINDABLE,
  and SUSPECT, and the site flags REGISTRATION, FORBIDDEN, and SUSPECT.
- When invoked by wizards, DOING displays the player flags DARK, UNFINDABLE,
  and SUSPECT.

  database version 7 may now be read.
- If a robot is @chowned as part of chowning all of a user's objects
  (via @destroy, @toad, or @chownall), the robot then owns itself and is
  not owned by the target player.

TinyMUSH 2.0 patchlevel 4:

- Dark wizards no longer generate '...has connected.' and
  '...has disconnected.' to those in the same room as them when they connect
  and disconnect.  Messages to their inventory are unaffected.
- Dark wizards no longer trigger OSUCC/ODROP/ASUCC/ADROP when traversing exits.
- If you connect to an already-connected character, others in the same room
  (and in your inventory) see the message '...has reconnected.'.
- If you QUIT from one session of a multiply-connected character, others in the
  room see '...has partially disconnected.'.
- @clone now lets you specify a different name for the new object
  (@clone <what>=<newname>)
- New switches for commands:
  @clone: /cost
- New option for @list: process
- Bug fixes:

    instead of "#-1 UNKNOWN ATTRIBUTE"
  o @search now correctly handles object-type-specific flags.
- The value of %# (and %n, etc) is now the object producing the message, rather
  than the object that ran the command that produced the message.  (Best
  example: A does '@tel B=#C', %# was A but is now B)

TinyMUSH 2.0 patchlevel 6:

- The u() function can now look up attributes on other objects.
- The CONNECTED flag of dark wizards is no longer visible to nonwizards.

NOTE: The ZONE flag and the USER and CONTROL locks don't do anything
at the moment.

TinyMUSH 2.0 patchlevel 8:

- Signal handling: SIGHUP performs a database dump, SIGQUIT, SIGTERM, and
  SIGXCPU perform a graceful shutdown, SIGINT is logged but ignored.
  SIGILL, SIGTRAP, SIGEMT, SIGFPE, SIGBUS, SIGSEGV, SIGSYS, and SIGXFSZ

- exam/parent now works with wildcarded attributes or no attribute
  specification.
- Many bug fixes.

TinyMUSH 2.0.8 (10/08/92)

  E PI: Arithmetic constants
  SEARCH: Supports range limits ala @search.
- Changed functions:
  ABS ADD EQ GT GTE LT LTE MAX MIN MUL NEQ SIGN SUB: Floating point support
  LOC RLOC ROOM: Obey UNFINDABLE flag on rooms
  CONN IDLE: No longer crash the server when given a bad playername
- Changed commands:
  @quota: Now takes a playername, not an objectname.
  @entrances @find @search: Support range limits.
  @verb now works if you don't control the victim, but the victim doesn't
  run the AWHAT attribute and you only retrieve the WHAT and OWHAT attributes
  if you have permission to read them.
- New help screen 'help function classes' lists functions by class.
- When checking for $-commands or ^-listens, HALTed objects are skipped
  entirely.  _IN THIS CASE ONLY_ attributes present on HALTed objects do not
  block out attributes on the parent of the HALTed object.
  POSS OBJ SUBJ - now can return information about faraway players.

TinyMUSH 2.0.8 patchlevel 1 (10/12/92)

- @sweep no longer shows nothing when given no arguments.
- @dolist now works as it used to in 2.0.p8 (attempted bugfix removed).

TinyMUSH 2.0.8 patchlevel 2 (10/21/92)

- Fixed @dolist to do the 'right' thing with curly braces: curly braces are
  only removed if they completely surround an argument (ie:
  '@dolist foo={bar}', but not '@dolist foo={b;a}r'.  Fixed @apply_marked and
  @wait in the same manner.  Note that the command to be run may remove braces
  also.
- Changed curly brace handling for @edit, @switch, and @verb so that only
  curly braces that completely surround arguments are removed (ie:
  'xxx, {arg}, yyy' but not 'xxx, {a,r}g, yyy'.
- div() is now strictly integer division again.
- Cleaned up signal handling somewhat, particularly the 'panicking' code.
- Corrected code for determining whether or not a PennMUSH database uses
  the builtin chat system.
- ^-listens no longer check output from the object itself.
- Removed all references to XENIX code.
- The internal RWHO now uses a much bigger buffer for reading.
- Changed RWHO defaults so they point to an operating mudwho server.
- @listmotd for wizards now shows the motd and wizmotd files.
- Never auto@destroy sacrificed players.

  [ Note: This new functionality is considered experimental and is not
    documented in the help file.  Please test it out and report bugs,
    omissions, and inconsistencies to mushbugs@caisr2.caisr.cwru.edu ]

- Absolute possesive substitution (%a, [v(a)]), returns its/hers/his/theirs.
- Partial support for plural gender: %s/%p/%o/%a return they/their/them/theirs
  when the Sex attribute starts with a p.  _NO_ other changes have been made
  (as in ... has/have arrived/connected/etc) so as to not break @listen/@ahear
  matching.
- New functions:
  APOSS(<obj>) - Absolute possesive, just like SUBJ/OBJ/POSS.
- Changes to functions:
  OWNER() - <obj>/<attr> syntax retrieves the owner of an attribute.
  LOCK() - <obj>/<lock> syntax retrieves the named lock from <obj>.
  ELOCK() - <obj>/<lock> syntax tests the named lock on <obj>.  If <lock> is
    not the default lock you must control <obj> or it must be set VISIBLE.
  LATTR() - <obj>/<wild-attr> returns attrs whose name matches <wild-attr>
- Evaluation locks:  @lock <what> = <attr>/<value>
  The contents of the <attr> attribute on <what> are evaluated substituting
  %#/%N/etc for the player or thing that is attempting to pass the lock.
  If the result of evaluating is equal to <value> (no wildcarding done, case
  does not matter), then the player passes the lock.

TinyMUSH 2.0.8 patchlevel 3 (10/23/92)

- Connect and disconnect messages are no longer broadcast to nearby audible
  rooms that are not linked via audible exits.
- Poses inside an audible object now deliver the PREFIX message to those
  outside the object.
- Non-$command attributes now block out $command attributes on parent objects.

  indirect lock check.
- Players may delete their aliases.
- Players are notified when they log in if their page lock is set.
- Wizards are notified when they log in if logins are disabled.
- Removed the getrusage() call from vattr_find() and vattr_nfind().

  Wizard-Visible Changes:

- New attribute: QueueMax

  Performance/Maintainability Changes:

- TinyMUSH 2.0.10 uses a slightly different flatfile and struct database
  format than 2.0.9.p2.  MUSH will transparently convert your database to the
  new format when it is read for the first time.  It is recommended that you
  back up your database before running TinyMUSH 2.0.10.
- There is now a second word of flags in the database.
- Money is now stored on a (hidden) attribute.  Money for active players
  is cached.
- Changes to players' Timeout attributes now take effect immediately.
- Players' pending queue sizes are no longer stored on an attribute, but are
  cached for active players.
- Attribute number lookups are now performed directly, instead of via a hash
  table.
- There are now separate MUSH-maintained flags for the presence of the
  LISTEN, FORWARDLIST, and STARTUP attributes.

TinyMUSH 2.0.10 patchlevel 1 (08/20/93)

- replace() now works correctly on a one-element list.
- The privilege requirement for the 'goto' command now also applies to using
  exits.
- extract() now works properly when using an alternate delimiter.

- The alias config directive no longer crashes the game if given only
  one argument.

  via a config directive.
- Setting or clearing the LISTEN or FORWARDLIST attributes no longer affects
  the DARK or JUMP_OK flags.
- db_unload now writes all attributes to the flatfile.
- elock() now works if you either control or are near both objects.
- has_flag() now correctly reports flags that reside in the extended flags
  word.
- iter() now returns a space-separated list instead of a delimter-separated
  list.

  '.. gave you ..' and 'You give ..' messages.
- The following functions now work correctly with multiple spaces between
  words (treated as one separator) and null words in non-space-delimited lists:
  extract() filter() first() insert() iter() ldelete() map() match() member()
  parse() remove() replace() rest() revwords() setdiff() setinter() setunion()
  splice() wordpos() words()

TinyMUSH 2.0.10 patchlevel 4 (10/26/93)

- New config directive: trace_output_limit.
- The default object matching code now checks for literal and quick-to-resolve
  matches ('me', 'here', #dbref, *player, etc) before checking nearby objects
  and exits.  If a literal match succeeds, the check for nearby objects and
  exits is not performed.
- Player names are now truncated to 16 characters in the WHO display.
- Original (Classic) TinyMUD databases may now be read in again.
- The following functions now trim their input lists if using a space as the
  delimiter: after() before() extract() filter() first() insert() iter()
  ldelete() map() match() member() parse() replace() rest() setdiff()
  setinter() setunion() sort() words()
- A memory allocation error in extending the user-defined attribute table
  has been corrected.
- @pcreate no longer crashes the game.

  values and empty strings, not a numeric sort.  (The empty strings are no
  longer considered numeric)

  object in the location containing the exits are now prefixed by the @prefix
  strings of both the object and the exit.
- @lock/tport now works correctly.
- When you try to teleport an object you control and the teleport fails, the
  failure messages are now displayed from the point of view of the victim
  object, not you.  You are still notified that the teleport failed.
- lexits() no longer returns dark exits in locations you don't control.
