=============================================================================
TinyMUSH 3.1 Changes
=============================================================================
TinyMUSH 3.1 beta 1 was released on May 8th, 2002.

-----------------------------------------------------------------------------
PATCHES SINCE THE 3.1 RELEASE
3.1 Patchlevel 6 -- January 12th, 2009
- Enhancement: A "reply" command allows you to reply to a page, including
being able to reply to the whole group of people paged along with you.
- Enhancement: Property directories (propdirs) offer the ability to
inherit attributes from multiple objects. If an object's parent chain
does not contain an attribute, the object's @propdir list is searched
for that attribute.
- A new special @hook, internalgoto, has been added. This offers the
ability to execute a hook on any type of movement, regardless of the
reason, with the before-hook executed before leaving a location, and
the after-hook executed when entering a location.
- Enhancement: The new /private switch to @function makes the register
environment of the called function private, ala uprivate() -- i.e.,
no registers are passed in, and any changes made to registers by the
function are discarded.
- Enhancement: The new /private switch to @hook makes the register
environment of the called hook private.
- Enhancement: PennMUSH-style #lamba anonymous functions are supported,
allowing functions like map() to take a string to execute rather than
requiring it to reside on an attribute.
- Enhancement: The iter() family has been extended -- iter2(), list2(),
whentrue2(), whenfalse2(), itext2() -- to allow a second list to be
simultaneously processed via the #+ string-token substitution.
- Enhancement: New function ifzero(), the reverse of nonzero().
- Enhancement: New function lregs() lists non-empty registers.
- Enhancement: If speak()'s first argument (the speaker) contains an '&',
it's used to specify a speaker name.
- Enhancement: @adisconnect is now passed all the statistics of the
session info, via the stack.
- Bugfix: In the ifelse() family, trailing space is no longer
accidentally eaten.
- Maintenance: Updated copyright to 2009.
3.1 Patchlevel 5 -- January 27th, 2008
- Enhancement: The new conf parameter local_master_parents allows the
parents of objects in ZONE-set parent rooms to be scanned for $commands.
- Enhancement: New Trace attribute flag, allows tracing of just a single
function.
- Enhancement: IDLE psuedo-command for idle keepalive, ala PennMUSH.
- Enhancement: @colormap allows a player to remap what colors he sees.
- Enhancement: @end (@break / @assert) ala PennMUSH/MUX -- terminate
action list and execute default based on a condition.
- Enhancement: New functions private() and uprivate(), which sandbox the
global registers for an evaluation.
- Enhancement: New function lreplace(), a multi-element replace.
- Enhancement: New functions usetrue() and usefalse() use conditional
expression if true/false, and default otherwise.
- Enhancement: New functions iftrue() and iffalse() act like ifelse() and
its boolean inverse, but substitute the condition in the resulting
evaluations as #$ (the switch token).
- Enhancement: New function qvars() reads list elements into local
registers, like xvars() does with variables.
- Enhancement: New function isort() sorts a list and returns its indices.
- Enhancement: extract() can take an output delimiter.
- Enhancement: ports() can take an empty argument, returning all ports;
permissions made configurable rather than hardcoded.
- Enhancement: push() with an empty argument now pushes an empty string
onto the stack, rather than returning an error.
- Enhancement: lor(), etc. return 0 on an empty argument, rather than an
error.
- Enhancement: @@() can have embedded commas.
- Enhancement: %i0 through %i9 are equivalent to itext(sub(ilev(),<number>))
and are identical to their PennMUSH counterparts, enabling the common
case of wanting to get the substitution from N levels up. %i-0 through
%i-9 are equivalent to itext(<number>).
- Enhancement: PennMUSH-style %+ substitution (returns number of arguments
on the stack).
- Enhancement: New conf parameter mud_shortname is used in logging, rather
than mud_name, if it's set. Useful for shortening very long game names.
- Bugfix: lunion() etc. correctly detect sort type when first argument
is blank. [3.1a7]
- Bugfix: writable() works on attributes that didn't previously
exist. [3.1a8]
- Bugfix: Don't leak memory on speak(). [3.1b3]
- Bugfix: Don't match an empty string to an exit (i.e., no foo;;bar). [2.0]
- Bugfix: @femit/spoof gives output properly. [3.1p2]
- Bugfix: Players who are hidden (Dark) can now have their names
partial-matched for page, etc. by players who can see hidden. [MUX]
- Bugfix: All site flags must be kept and checked (so, for instance, you
can restrict both creates and guests). [3.0b8]
- Bugfix: Global registers must be cleared when doing notification. [2.0]
- Bugfix: Bad @cron syntax can no longer cause a loop. [3.0b8]
- Bugfix: Message to/use of an emptied comsys channel can no longer cause
a crash. [3.0b14]
- Bugfix: flag_access must have a permission. [2.0; Brazil]
- Maintenance: Updated GDBM's AutoConf to version 2.59.
- Maintenance: Updated GDBM's LibTools to version 1.5.22.
- Maintenance: Removed unused variables related to @program. Per Brazil.
- Maintenance: Updated copyright to 2008.
- Compatibility: Enables TinyMUSH to read the escapes of cr/lf add to the
TinyMUX flatfile. Per Brazil.
3.1 Patchlevel 4 -- December 19th, 2006
- Fixed Always clear @prog data on logout
- Fixed tools (src/tools). Add an install tag to the tools makefile.
- Update LibTools to version 1.5.22.
- Update AutoConf to version 2.59.
- Fixed function logf() in udb_* conflict with build-in function logf(),
rename the function to warning().
- Remove unused port-concentrator code.
- Automated build of TinyGDBM within ./configure.
- Updated the build process a bit to keep in line with autoconf
standards.
3.1 Patchlevel 3
- Fixed Update script to work with Sourceforge's new web services.
- Bugfix for integer overflow in PCRE repeat counts.
- Removed stale code in add_player_name.
- Refactored the logged-out commands code, removing some unreachable
code in do_command, clarifying how logged-out commands are handled,
and fixing a reference to freed memory.
- Improved performance of scramble() and reverse() on strings with
less ANSI color.
- Avoided unnecessary attribute scans in Hearer().
- Removed duplicated code in handle_ears().
- Minor nitpicks in sweep_check() and fh_hear_bit().
- Renamed CLONE_PARENT to avoid conflict with Linux 2.4 sched.h.
Patch from Brazil. [2.0]
- Fixed potential null-dereference in player cache -- pcache_find()
no longer returns null and all callers must use Good_owner() first.
Reported by Brazil. [2.0]
- Fixed double-evaluation of arguments in columns(). [MUX; Brazil]
- Fixed lack of evaluation of delimiter arguments in list() and loop().
[3.0]
3.1 Patchlevel 2
- Startmush now accept start/stop/restart/reboot switches. You can
also pass the name of the config file you want to use instead of
the default 'mush.config' one.
- Removed hardcoded binaries path from the engine, a new command
line switch ( -b binpath ) new feed the engine with the correct
value. The engine can now run its binaries from any directory,
not just ./bin/. (slave path was hardcoded.)
- Removed hardcoded textfiles path from the engine, a new command
line switch ( -t textpath ) now feed the engine with the
correct value. This eliminate the need of adding every
textfile in the configfile if someone want to change the
game's text directory.
- The engine is now able to find the data directory and names of
the db/crash files from the command line. ( -d datapath,
-g gdbmfile and -k crashfile) The configuration parameters
'database_home', 'crash_database' and 'gdbm_database' are
still avalable for backward compatibility.
- A new helper (logwatch) replace the 'tail'/'awk' script
used to print the first lines of the log during statup.
this solve the problem of having a zombie tail command
left running when awk cut its pipe.
- Added EXIT, ROOMS and VEHICLE topics in qhelp.txt.
- Fixed a memory leak in sql_query function where result was stored but
never freed so whenever a query returns an empty result it leaks a
mysql result structure. [3.0; Dan Ryan]
- Added /spoof switch for @fsay/@fpose/@femit.
- Modified the documentation to properly reference @speechformat
instead of @speechmod [3.1b7; Jared Robertson]
- Changed the wizhelp topic text of LOGGING and INHERITANCE to
"This topic hasn't been written yet." [MUX; Jared Robertson]
- Added a REGISTRATION wizhelp topic (was referenced by @PCREATE and
REGISTER_SITE) [MUX; Jared Robertson]
3.1 Patchlevel 1 -- August 11th, 2004
- Fixed a bug in dbconvert where the cache wasn't flushed before
closing the database, creating an incomplete database. [3.1p0]
-----------------------------------------------------------------------------
CHANGES TO THE BASE SERVER
- The licensing scheme has been changed to the Artistic License.
- A new script, Update, automatically downloads and applies official patches
to TinyMUSH 3.
- The Backup, Restore, and Archive scripts can now look at a backups
directory (set in mush.config). The default compression program is
also now set in mush.config. Compression extensions are used
correctly, and the bzip2 format is supported.
- The Startmush script handles KILLED and CRASH databases more elegantly.
- The Restore script can handle the archives produced by Archive.
- Dynamically loadable modules. There is now an interface for writing your
own hardcode extensions to the server, and loading them at runtime.
The comsys and mailer are now loadable modules; the USE_COMSYS and
USE_MAIL #ifdef's and the have_comsys and have_mailer conf directives
are no longer needed.
- '@list memory' gives a breakdown of the memory used by various constructs.
- Many changes and improvements to caching.
- Instead of starting the cache at some fixed width and depth, and
growing the depth (but not the width) to whatever size is demanded by
the game, which can cause "cache bloat" if a very large number of
objects gets loaded into the cache as part of a single operation,
the total size of the cache is fixed -- the amount of memory that
the cached data takes cannot exceed a specified limit. This is
configurable via the cache_size parameter.
- Removal of elements from the cache is based on "least recently used"
rather than "not frequently used".
- Attribute caching is now used, with cache bypass in situations where
this is not efficient.
- @list cache shows an object-based summary of cache information.
@list cache_attrs shows the full cache.
- Various changes to the database structure:
- GDBM databases now contains meta-data that allow easier recovery of
databases that have been trashed (due to a host machine crash or
running out of disk space, for instance). A new script, Reconstruct,
calls the new recover binary to attempt to rebuild damaged databases.
- There are no longer separate structure and GDBM files ("numeric" and
"string" databases).
- GDBM's native free space management has been enabled. Optimized dumps
have been disabled by default. Our copy of gdbm includes a bugfix that
enables the free space management and other options, so we build it as
libtinygdbm.a to avoid linking netmush with an unmodified gdbm.
- File locking has been added for some circumstances, so dbconvert waits
for netmush to finish writing, before it starts reading, ensuring
consistency when backing up a running MUSH.
- dbconvert is now just a symlink to netmush; its functionality has been
merged into the main program.
- Making a flatfile now automatically cleans the attribute table of
dead attribute name references, so the @dbclean command is no longer
needed. (You can pass a -q option to dbconvert to prevent attribute
cleaning, if for some reason you want to avoid this.)
- Clean flatfiles are now produced by SIGUSR2. SIGQUIT causes a graceful
shutdown.
- Extensive work on improving autoconf and libtool use (thus improving
portability). Compile-time options are now specified as switches to
the configure script.
- Garbage is trimmed from the top of the database, if possible, reducing
bloat due to tail-end garbage.
- When an object name is ambiguously matched (i.e., potentially matches
several objects), the match is now truly chosen randomly; in the past,
the last match was heavily favored.
- Help entries can now have multiple index terms.
- A rewrite has begun on the help files.
-----------------------------------------------------------------------------
CHANGES TO CONFIGURATION PARAMETERS
- Conf parameters that are dbrefs (such as master_room) are now sanity
checked, both when they are set and when a @dbck is run. Also, a dbref
as well as a number can be used, i.e. the syntax 'master_room #2' is
now also valid (whereas 'master_room 2' was previously required).
- A new conf parameter, attr_type, allows attributes whose names match
certain wildcard patterns to be given certain default flags. Attribute
names can now start with '_'. (To implement a rule like, "All attributes
whose names start with '_' can only be set by wizards," you would add,
"attr_type _* wizard" to your conf file.)
- A new conf parameter, database_home, has been introduced. This is
the directory where all the database files are stored. This eliminates
the necessity to provide a directory path for input_database, etc.
- New conf parameters exit_proto, room_proto, etc. allow one object of
each type to be defined as the "prototype" for new objects of that
type. When an object of that type is created, it copies the flags,
parent, zone (if 'autozone' is off), and attributes of the prototype;
the effect is similar to cloning.
- New conf parameters exit_attr_defaults, room_attr_defaults, etc.
allow one object of each type to be defined as the repository for
"attribute defaults" for many built-in attributes, such as
attr/oattr pairs (@desc, @odesc, @succ, @osucc, etc.), @conformat,
and @exitformat, as well as user attributes that have a global attribute
flag of 'default'. These defaults override the attributes set on
objects of that type (the local value of the attribute is passed
to it as %0, for evaluation). This allows the global definition
of formats for those attributes, without requiring a global
parenting scheme or an unusual attribute naming scheme. Objects
with the FREE flag ignore attribute defaults.
- The new conf parameter, c_is_command, controls whether %c is last
command (default) or ANSI substitution.
- The new conf parameter forwardlist_limit allows you to set a limit
for the number of objects that can be listed in a single @forwardlist.
- The new conf parameter function_cpu_limit allows you to set a limit
for the number of seconds of CPU time that can be taken up by
function evaluations associated with a command.
- The new conf parameters guest_basename, guest_prefixes, guest_suffixes,
and guest_password allow flexible naming of guests. See the FAQ for
details. (The guest_prefix parameter is now obsolete, and has been
removed.)
- The new conf parameter huh_message lets you change the Huh? message
that is displayed when a command cannot be matched.
- The new conf parameter power_alias allows you to set aliases for
powers. The compat.conf file now contains aliases for mapping PennMUSH
and TinyMUX power names.
- The new conf parameter visible_wizards (disabled by default) results
in DARK wizards being hidden from WHO (and related things), but not
being invisible and silent. This prevents accidental or deliberate
spying by DARK wizards.
- The new conf parameter wildcard_match_limit restricts how extensive
of a recursive search is performed when attempting to match a pattern.
-----------------------------------------------------------------------------
CHANGES TO ATTRIBUTES
- @aconnect and @adisconnect attributes are triggered consistently on all
connections and disconnections, with a reason in %0 and the player's
resulting number of open connections in %1.
- Players can now specify multiple aliases for themselves (up to
the conf parameter player_aliases_limit), via @alias, separating
aliases with ';'. Players no longer inherit @alias from their
parent (this never made sense, or worked properly, anyway).
- @conformat and @exitformat get their visible contents/exits lists
passed as %0.
- A new attribute, LastIP, tracks the last IP address of a player.
When Lastsite is set, the identd user and hostname are no longer
truncated.
- The new attribute @nameformat controls the display of location's name
when someone looks at the location.
- The format and text of a say or pose can be arbitrarily altered, via the
@speechformat attribute and SPEECHMOD flag on the speaker, or the
speaker's location.
- General visibility of an attribute is now consistently controlled by the
'visual' attribute flag (previously it was controlled by 'private' on the
global attribute definition, and 'visual' on the specific attribute).
Attributes default to not visual; if you were previously defining global
attributes with '!private' (via @attribute/access, user_attr_access, etc.)
you should now define them as 'visual'. Databases are automatically
converted to have the appropriate attribute flags.
- Visibility restrictions on attributes have been sanitized, so they are
consistent across commands and functions.
- Attribute flags that have no meaning on a global basis can no longer
be set globally via @attribute and the like, thus reducing confusion.
- The global flags for attributes are now shown in parentheses, when
an object is examined.
- A new attribute flag, 'case', controls whether regular expression matching
is case-sensitive, for $-commands, ^-listens, @filter, @infilter, and
@listen.
- A new attribute flag, no_name, controls whether or not the actor's
name is prepended when an attribute is used as an @o-attr, such as
an @osucc or with @verb.
- @filter, @infilter, and @listen do regular expression matches if
set 'regexp'. They do not evaluate themselves before matching,
if set 'no_parse'.
- A new attribute flag, 'rmatch', assigns the results of a $-command's
wildcard-match, to named local registers, as well as to the stack.
Based on an idea from KiliaFae.
-----------------------------------------------------------------------------
CHANGES TO FLAGS AND POWERS
- An object with the new attr_read power is able to see attributes
with the 'hidden' attribute flag, just like Wizards and Royalty can.
- An object with the new attr_write power is able to set attributes
with the 'wizard' attribute flag, just like Wizards can.
- An object with the new link_any_home power can set the home of any
object (@link an object anywhere), just like Wizards can.
- If a wizard connects while DARK, they are reminded that they are
currently set DARK. Also, wizards are notified when they are set
DARK due to idle-wizards-being-set-dark. A player must have the
Hide power or equivalent in order to auto-dark.
- There is a new type of lock, the DarkLock, which controls whether or
not a player sees an object as DARK. Based loosely on a patch by
Malcolm Campbell (Calum).
- There is a new power, Cloak, which is God-settable. It enables an
object which can listen (such a player or puppet) to be dark in the
room contents and movement messages; previously, this was only true
for listening objects both Dark and Wizard. Note that since wizard
Dark is now affected by the visible_wizards config parameter, if that
parameter is enabled, wizards will need this power in order to
become invisible.
- The Expanded_Who power no longer grants the ability to see Dark
players in WHO. (Previously those with the power could, but weren't
able to see them in functions. Use the See_Hidden power to grant
the ability to see Dark players.)
- The new ORPHAN flag, when set on an object, prevents the object from
inheriting $-commands from its parents (just like objects in the master
room do not inherit $-commands from their parents). This allows you to
@parent a command object to a data object, without worrying about the
overhead of scanning the data object for $-commands.
- The new PRESENCE flag, in conjunction with six new locks (HeardLock,
HearsLock, KnownLock, KnowsLock, MovedLock, MovesLock) supports "altered
reality" realm states such as invisibility.
-----------------------------------------------------------------------------
CHANGES TO COMMANDS
- Some commands that would normally be queued can now be executed
immediately, using the /now switch: @dolist/now (@iter), @force/now,
@switch/now (@branch), @trigger/now (@call), @verb/now
force() and trigger() now behave like @force/now and @trigger/now.
The new conf parameters command_invocation_limit and
command_recursion_limit are used to limit this behavior.
- A user-defined $-command is executed immediately if the attribute has
the new Now attribute flag.
- Commands added via @addcommand are now run immediately. Also, these
commands now respect an escaped-out ':', as well as the regexp and
case attribute flags.
- A new switch, @addcommand/preserve, causes the text of an added
command to be executed by the player, not by the specified object,
unless the player is God (for security reasons).
- Custom comsys headers can now be specified for channels, via
@channel/header. These headers can be listed via @clist/header.
Also, the @channel command now interprets its arguments, and channel
descriptions are passed through a sanity check.
- The new Spoof comsys flag, when set on a channel, replaces player names
with their comtitles, instead of prepending the comtitle to the player
name.
- @cpattr can copy multiple attributes at a time.
- Exits can now @destroy themselves.
- @doing (including @doing/header) now takes a /quiet switch.
- A new command, @floaters, shows floating rooms. Floating rooms are no
longer reported by @dbck, and thus the FLOATING flag has been eliminated
(since it's no longer needed to suppress @dbck spam).
- The new /permit switch to @hook allows the permissions for a built-in
command to be defined via a user-defined function.
- Functions defined via @function can be listed via @function/list.
- Function permissions can be listed via '@list func_permissions'.
- Lock syntax is now always sanity-checked. Unbalanced parentheses within
a lock are no longer permitted.
- The new @log command can be used to log arbitrary messages to the
logfile(s).
- When you log in, you are warned if you are currently in the midst
of writing a @mail message.
- A @mail recipient now receives only a single copy of a @mail message,
even if he appears multiple times in the list of players the message
is to.
- @mail now has real carbon-copy and blind-carbon-copy. Patch from
Simon Bland.
- @pemit/list now obeys the same permission checks as @pemit, including
obeying pemit_any as well as restricting use of the /contents switch.
- The @emit, @oemit, @femit, @fpose, @fsay, page, pose, and say commands
now take a /noeval switch. (Analogous to the /noeval switch for @pemit.)
- The @pemit and @oemit commands now take a /speech switch, which makes
the message subject to Presence checks.
- The new @redirect command can be used to redirect Trace, Puppet, and
Verbose output from an object, to a player other than the object's
owner. The REDIR_OK flag allows an object's output to be redirected
by someone who does not control it, thus allowing non-Wizards to
participate in mutual debugging sessions. Based on an idea from
AlloyMUSH.
- The new @reference command creates named references ("nrefs"), which
behave like aliases for dbrefs, in the form of '#_<name>'.
- When speech is formatted, with the exception of say and @fsay,
there is now a grammatically-correct comma before "says". The
new conf parameter say_uses_comma will insert the comma for
say and @fsay, as well.
- If the new conf parameter say_uses_you is turned off, the say and
@fsay commands will always show '<name> says' rather than 'You say'
to the speaker. This is more convenient for environments where
activity is often logged and shared.
- A @dbck is automatically done before a @restart or normal @shutdown,
so recycling cleanup is done first, thus avoiding inconsistencies
upon startup.
- The @teleport command can now be used on exits. Players with the
Open_Anywhere power can now drop or @teleport exits to any location.
- Specifying an object to @trigger is now optional; if no object is
specified, the object defaults to 'me'.
- @verb now takes a no_name switch, which prevents the actor's name from
being prepended to the default o-message.
- Attributes containing a $command or ^monitor can now be @trigger'd
directly, as well as used as @a-actions; everything before the first
un-escaped ':' is ignored. Based on an idea from PennMUSH.
-----------------------------------------------------------------------------
CHANGES TO FUNCTIONS
- Multi-character input and output delimiters are now supported for
most functions.
- There are additional global registers, %qa-%qz (based on an idea from
PennMUSH). Furthermore, arbitrarily-named global registers can be defined
on the fly (up to the conf parameter register_limit, per action list).
setq() can now take multiple name-value pairs.
- The caller of a function can now be tracked via %@; it's normally equal
to the enactor, except where u()-type functions, including objeval()
and @functions, are called. This provides better security-checking
capabilities. Based on an idea from PennMUSH.
- The %m substitution can now be used for last command (MUX2 compatibility;
%c is the usual substitution).
- Brackets are no longer required around eval-locks, hooks, or @exitto code.
- The *<player> syntax is supported in many more places.
- There is a more informative error message when a function is given the
wrong number of arguments. Idea from Philip Mak.
- Extended regular expression syntax from Perl 5 is now supported.
This is based on the PCRE library, as modified by the PennMUSH team.
- New regular expression functions: regedit(), regediti(), regeditall(),
regeditalli(), regrab(), regrabi(), regraball(), regraballi(),
regrep(), regrepi(), regmatchi(), regparsei().
- Added a variety of comsys-related functions: cemit(), comalias(),
comdesc(), comheader(), cominfo(), comlist(), comowner(), comtitle(),
cwhoall().
- cwho() now only returns what's listening.
- Added fcount(), fdepth(), ccount(), cdepth(), for getting function and
command invocation and recursion counters. Based on a concept from
Shadowrun Denver MUSH.
- The filter(), filterbool(), map(), and while() functions pass the
position of the element in the list as %1. fold() passes the position
of the element in the list as %2. foreach() passes the position of
the character in the string (starting from position 0). Based on
an idea from PennMUSH.
- The idle(), conn(), and doing() functions can now take a port number.
- The escape(), secure(), capstr(), lcstr(), and ucstr() functions now
handle ANSI properly.
- Added border(), rborder(), and cborder(). These are word-wrap functions
which can left/right/center-justify text within the field, and add
left and right-margin borders.
- Added cand(), cor(), candbool(), and corbool(), similar to and() etc.,
except these functions stop evaluating their arguments once a terminating
conclusion is reached. Based on an idea from PennMUSH.
- chomp() can now handle a lone CR or LF.
- Added choose(), weighted-random-choice pick of an element from a list.
Idea from FiranMUX.
- Added connrecord(), connected player record (as in WHO).
- Added elockstr(), which evaluates a target against a lock string.
Idea from Joel Ricketts.
- Added entrances() function, similar to @entrances command. Based on an
idea from PennMUSH.
- You can now get attribute flags with flags(<obj>/<attr>). Based on an
idea from PennMUSH.
- Added graball(), which is to grab() what matchall() is to match().
- Added group(), for splitting/sorting a list into groups.
- hasflag() can now detect object types.
- Added hasflags(), which can operate on multiple lists of flags and
types, returning true if all elements in any of the lists are true.
- Added hears(), moves(), and knows() functions for checking Presence
permissions.
- Added helptext(), which retrieves an enetry from an indexed textfile
(i.e., help, news, or anything else added via the helpfile or
raw_helpfile conf directives).
- The third argument to ifelse() -- the 'false' result -- is now optional.
- Added istrue() and isfalse(), which are basically iter()-style filterbool()
and its reverse.
- Added ilev(), itext(), and inum() functions, for retrieving data
from multiple levels of nested iter()-type functions. Based on
an idea from PennMUSH.
- Added itemize() function, which formats a list of items. Typically used
to turn a list of words into something like "a, b, and c". Based on an
idea from PennMUSH.
- Last-accessed and last-modified timestamps are now tracked for all
objects. The timestamps are visible on an 'examine', and the seconds-value
can be retrieved via the new functions lastaccess() and lastmod().
- Added ledit() function, a mass find-and-replace on a list which can
replace many instances of nested edit() calls.
- lpos() can now check multiple characters at one time. Based on a
suggestion from Joel Ricketts.
- lpos(), lattr(), lexits(), lcon(), xcon(), children(), lparent(), and
the grep() family now take an output delimiter.
- The ljust(), rjust(), and center() functions can take multi-character
fills.
- The lunion(), linter(), and ldiff() functions are similar to setunion(),
etc., but an attempt is made to autodetect the list type and sort
accordingly, or you can specify a sort type, as you can with sort().
- The modify() function now takes lists, enabling multiple variables
to be modified at once.
- The behavior of remainders in division with negative numbers is
now consistent (rather than being compiler-dependent), including
new modulo(), remainder(), and floordiv() functions. The mod()
function is now an alias for remainder(), which is closest to
the old mod() on most platforms; if you want it to be an alias
for modulo() instead, change it in alias.conf
- munge() now passes its input delimiter to the u-function, as %1.
Idea from PennMUSH.
- Added nattr(), which counts the number of attributes on an object.
- Added objcall(), which evalutes the text of an attribute from another
object's perspective, like a combination of u() and objeval(). Idea
from Joel Ricketts.
- Added oemit(), which is the function equivalent of @oemit.
- pos() strips ANSI out of the string to search for, in addition to the
string to search within.
- rloc() now returns the destination of an exit.
- New search classes -- ueval, uthing, uplayer, uroom, uexit -- have
been added, allowing a u-function to be called for evaluation. This
makes it unnecessary to deal with brackets-escaping issues.
- sees() can now evaluate the visibility of exits as well as things.
Also, a small bug has been fixed: the see_owned_dark calculation in
sees() now uses the object doing the looking, not the player invoking
the function.
- Added session(), which returns command count, bytes of input, and
bytes of output associated with a port.
- Added speak(), which formats speech strings and can parse and transform
them.
- Added store(), which is basically to setx() what setr() is to setq().
- The new structure functions read() and write() allow the use of an
"invisible" delimiter, which permits data to be stored in delimited
lists without worrying about user-provided data containing the
delimiter character. The delimit() function processes a stored
list, substituting a separator string for a delimiter.
- Added table(), tables(), rtables(), and ctables() functions. table()
is based on an idea from PennMUSH, formatting text within a table of
equally wide columns. The other three functions format text within
a table of variably-wide columns (left/right/center-justified), with
left and right-margin borders.
- Added timefmt() function. This is essentially an interface to the C
library function strftime(), allowing the time to be formatted in
psuedo-arbitrary ways. Based on an idea from PennMUSH.
- translate() now handles tabs.
- trim() now handles multi-character trim strings.
- Added sind(), cosd(), tand(), asind(), acosd(), atand() degree-based
trigonometry functions.
- Added until() function, which is similar to while(), except it operates
on multiple lists and terminates on a regular expression condition.
- valid() can now detect valid attribute names and player names, for
PennMUSH compatibility.
- Added whentrue() and whenfalse() functions, which go through a list
iter()-style until a terminating boolean condition is reached.
- Added wildgrep(), wildmatch(), and wildparse(), which are similar to
regrep(), regmatch() and regparse(), but work against wildcard patterns
rather than regexps.
- Added writable() function, which returns 1 if object X can set an
attribute A on object Y.
- Added @@() function, which is like null(), but does not evaluate
its argument.
- elock(), hasflag(), haspower(), and type() now all return #-1 NO MATCH
when they can't find the object they're checking. Previously they
returned #-1 NOT FOUND; for consistency's sake, they now behave like
everything else.
-----------------------------------------------------------------------------
OTHER CHANGES
- Improvement in logging facilities.
- Dynamic allocation of string conf parameters.
- Break-out of functions into many files, sorted by function type.
Break-out of the command tables into a separate file, for ease of
maintenance.
- ANSI, particularly in functions, is handled more consistently and more
sanely. Some string and list functions have also been optimized. These
changes are known to be incomplete as of TinyMUSH 3.1 beta 1.
- Similar functions may use the same handler internally, called with
different flags specified in the function table, so adding families
of similar functions does not imply code bloat. Several groups of
functions (trigonometry, logic, etc.) have been condensed into common
handlers.
- Better handling of the slave for DNS and identd lookups.
- Replaced the random number generator with Mersenne Twister. Use
derived from PennMUSH, which derives it from MUX2.
- Other cleanup in many parts of the code, including performance
enhancements and significant reductions in memory used.
- Fatal signals now produce cleaner coredumps, but two signals are
required to generate a core file. Based on a patch from Amos
Wetherbee.
- Many portability improvements, including support of UWIN, so TinyMUSH 3
can be run under Windows.
=============================================================================
TinyMUSH 3.0 Changes
=============================================================================
This change list details user-visible or otherwise highly significant
changes in TinyMUSH 3.0. The bugfixes and general code reworking done
in the course of merging TinyMUSH 2.2 and TinyMUX line-by-line, as
well as throughout an extensive cleanup, bugfix, and
performance-enhancement effort, is too extensive and complex to
readily be listed here.
Note that these are only changes that are completely new to both
TinyMUSH 2.2 and TinyMUX; enhancements that were in one server but not
the other have been listed in the conversion notes for both servers.
TinyMUSH 3.0 beta 1 was released on September 27th, 1999.
The "full", gamma release of TinyMUSH 3.0 is dated December 1st, 2000.
-----------------------------------------------------------------------------
CHANGES TO THE BASE SERVER AND SERVER CONFIGURATION
- Build script allows "single-step" configuration, build, and installation.
- Backup and Restore scripts simplify backup maintenance. Archive script
allows the archival of all the important files.
- Index script detects help-style files (help, news, etc.) and indexes
them. This is now called by Startmush.
- Bug reporting is easier, via the ReportCrash script, which analyzes
core files and emails the results to the bug reporting address.
- GNU dbm 1.8.0 is required. Database code has been rewritten to take
advantage of its features. Dumps are now automatically optimized (though
you can turn this off using the new conf parameter opt_frequency), and
you may safely back up the MUSH while it is running, either internally
(through @dump/flatfile) or externally (through the Backup script).
- An interface to an external SQL database is now supported, through
the SQL() function and supporting administrative commands. Currently,
modules for mSQL and MySQL are available.
- There is now a generic indexed-textfile facility, allowing 'news'-like
commands and their associated files to be specified via the 'helpfile'
and 'raw_helpfile' parameters in the conf file.
- The readability of a configuration parameter can be set via the
config_read_access param, and can be listed with @list config_read_perms.
A config() function allows players to obtain the value of a configuration
parameter that they have permission to read.
- The new game_log and divert_log parameters allow the logs for different
types of events to be sent to different files. The new @logrotate
command allows these logfiles to be rotated while the game is running.
Logfiles are also rotated when a @restart is done. Old log are marked
with a timestamp in seconds. The new Logclean script simplifies
cleanup of old logfiles.
- Command-table additions (@addcommand and family) are supported (a
cleaned-up version of the MUX implementation). Three new conf parameters:
- addcommands_match_blindly (defaults to 'yes', controls whether or not
a 'Huh?' is produced when a match on an @addcommand'd command doesn't
actually match a $command)
- addcommands_obey_stop (defaults to 'no') controls whether or not an
object with the Stop flag actually enforces a stop of match attempts
when a match is found on an @addcomand for that object.
- addcommands_obey_uselocks (defaults to 'no') controls whether or not
the uselock is checked when an added command is matched.
(The defaults are MUX behavior; we suggest that the reverse of the
defaults is more desirable, though.)
- There are now command "hooks", implemented via the @hook command. Hooks
are functions which execute before and/or after a built-in command;
using side-effect functions, it is thus possible to customize a
command without needing to write a full-blown @addcommand for it,
or to execute things before/after every move through an exit.
- The term "zone" is now used for two things: MUX-style control-oriented
zones, and 2.2-style local-master-rooms. Both types of zones default
to on (local_master_rooms and have_zones conf parameters). MUX-style
zones now use ControlLock rather than EnterLock, and only objects
set CONTROL_OK may be controlled by a ZMO; this provides slightly
better security. A new config parameter, 'autozone', controls
whether or not objects are automatically zoned to their creator's
ZMO at the time of their creation.
- The comsystem has been rewritten, resulting in a variety of minor
syntax changes and alterations and enhancements to functionality.
Default channel aliases can now be set with the public_calias and
guests_calias config parameters.
- Variable destination exits are implemented, via the "variable" keyword
and the ExitTo attribute; the destination of the exit is determined when
it is used. The link_variable power has been added in support of this.
(This works in a way similar to PennMUSH's variable destination exits,
but ExitTo was used instead of Destination, to reduce likelihood of
previous attribute conflicts.)
- Optional uselock checking for global aconnects has been implemented.
(2.2 had this by default; MUX did not have this.)
- The disconnect reason is passed for master-room disconnects, too.
- When the new conf parameter dark_actions is enabled, objects set Dark
still trigger @a-actions when moving, unless the /quiet switch is
specified.
