CHANGES,v 2.50 1997/08/30 07:21:29 dmoore Exp
Changes are now semi-sorted into the categories of player, wizard, admin,
and programmer. The player and wizard lists are things that might affect
those people. The admin and programmer sections have some overlap, and
my criterion for the division is that admin items are usually normal
header file settings. Programmer section contains information about
changes to more internal structures.
2.4:
----
PLAYER:
o New strftime formats %i and %J.
o Players are now notified when they are forced by a wizard.
o In the case of a remote kill, both the room of the killer and the
killee are notified of the kill.
WIZARD:
ADMIN:
o New script 'admin/scripts/findflag' which prints out dbrefs
having a given flag. Ex: findflag DARK in.foo.new
PROGRAMMER:
o Changed the muck_strftime to take an extra argument to
let you use GMT time instead of the default of local time.
o Added %i to muck_strftime which returns a value like the
idle time for the WHO list.
o Added %J to muck_strftime which is the same as %j, except it
uses leading spaces instead of leading 0s. This is used for
connect time in the WHO list.
o Changed the connect time/idle time for WHO list to use
Bufsprint with %T.
o Fixed typo in log.c in log_last_command.
o Added HAVE_STRERROR to disable setting of strerror macro,
instead of old checking for an already existing macro by that
name.
o Added HAVE_TZSET for people who have it. Now you could
change the timezone of the mud by just setting an environment
variable TZ (perhaps in your restart script).
o Added HAVE_TZNAME for places (sys5) which don't have the
time zone in the struct tm, but do have it in tzname.
o Fixed up a call to strcasecmp and 3 to strncasecmp which showed
up incorrectly. Changed to muck_stricmp, and muck_strnicmp.
Removed HAVE_STRCASECMP.
o Added ALIGN_BYTES to tell muck_malloc and debug_malloc about
alignment requirements.
o The tracing option for debugging malloc now checks the magic
numbers for the unfreed resources, to detect any overruns
they may have had.
o Fixed more getdtable size portability.
o Check more signals for existance on particular system before
using them.
o Fixed bug in compiler which would allow a tab to be placed in
a string.
o Fixed a bug with code structures where the refcount was decremented
inappropriately if a program had a ' construct and failed to
compile. Removed clear_inst and clear_inst_un. Now use
clear_inst_code if you are nuking an inst which is in a code
struct (ie clear_code or in compiler). Use clear_inst_interp
if you are nuking an inst that is on a muf stack or similar
(ie anything in the interp).
o Fixed a bug with failed forks preventing future forked dumps.
o A failed 'accept' call will no longer cause the server to exit,
seen in the logs as: 'PERROR: main_loop: new_connection'.
Now it will be logged, but the server continues running as before.
o Added log_sanity command, for use by sanity routines.
o On systems without 'random', use 3 calls to rand to hopefully get
31 bits of a random number.
o When doing batch input processing, kick out of the loop to allow
output at reasonable intervals to keep perceived interactivity
level higher.
o Added a send_except call to interface.c to allow for more
efficient implementation of notify_except.
o Fixed bug which gave people 1 penny for every unlinked exit they
owned, anytime anyone did a recycle.
o Added make2_shared_string to speed up prim_strcat.
o Sped up property hashtable comparision, to avoid a stricmp call.
o Changed con_info in interface.c to return the time of the last
player command, not the idle time, since calling time() can be
very slow. Now prim_conidle calls time() itself when needed.
o Added a match_everything call to match.c and made some routines
use it (more should be done). Improved ordering of operations in
match_everything provides significant speedups for .pmatch and
similar operations in rooms with many objects.
o The muf `exit' primitive has been replaced with INST_EXIT.
o A new instruction INST_PICK acts like pick+1 and is used for dup,
swap, and pick by the optimizer when the operation is guaranteed
to succeed.
o New instruction INST_WIZCHECK forces a check for the state of
the frame to have wizard permissions. It is emitted by the
optimizer in front of primitives which require wizperms.
o New file compile/optimize.c implements compile time stack depth
and argument type checking. Other small optimizations are done
including some dead code elimination and minor constant folding.
o Various changes to the interpreter to speed it up quite a bit.
o The split bytecode and bytedata has been unified again. The
space savings were insignificant.
o The muf flag? primitive now respects QUELL when checking for
the GOD flag (when GOD_FLAGS are enabled).
2.3 beta patchlevel 3:
----------------------
PLAYER:
o @stat, @find, @owned are now free for players.
o Server page costs PAGE_COST not LOOKUP_COST now. PAGE_COST
defaults to 0. If a player has negative pennies, they can't page.
o Object matching via '*player' is always free.
o Made @stat return global mud information for all players, and allow
any player to @stat themselves.
o Whispering to an object now yields an error rather than just
saying that the object is not connected.
o Added a magic cookie for '#' -> 'poundsign'.
o Programs no longer have that default 'scroll' message for a desc.
o Run programs on #0 and player on connect and disconnect. Look
in properties named _connect and _disconnect. Acts like @desc,
in that you'd do 'message' or '@545 arguments', etc. If you use
MUF_CONNECT_HOOKS.
WIZARD:
ADMIN:
o No more config.h in distribution. Copy include/config.h-dist
to include/config.h and edit that. The files config.h-temp
and config.h-druid contain samples of a different way
of handling config.h.
o Portability change: added HAVE_UNISTD_H in config.h.
If HAVE_UNISTD_H is true, then sysconf is used to determine the
maximum number of file descriptors instead of getdtablesize.
This will also hopefully cut down on a lot of warnings for
compiling the interface/* files on certain machines.
o Portability change: Defaults to now using waitpid (posix)
instead of wait3 (bsd) to collect child processes. Can force
wait3 in config.h.
o Added NEED_TIME_ZONE to config.h, for those systems which don't
have tm_zone field in their struct tm.
o Renamed LOG_STATUS, LOG_MUF, LOG_GRIPE to *_LOG and moved into
params.h
o The locations of the various files *_FILE in config.h have been
moved to params.h.
o Added DEFAULT_<type>_FLAGS, where <type> is ROOM, PLAYER, THING,
EXIT, or PROGRAM. Set in config.h.
o If you want god flags, set GOD_FLAGS in config.h.
o Put in code to dump the various statistics tracked by the
hashtable routines at shutdown time into a file named by INFO_LOG.
o Got rid of COMPILE_ON_LOAD and INLINE_BUFFER. The new
defaults are as off the former was false and the latter was true.
o Fix for broken tolower in ansify.h. Missing NSIG guess in
ansify.h (you may find it in /usr/include/sys/signal.h).
If you don't have random/srandom check ansify.h.
o Have the logging of restricted flags use the full real name of the
flag instead of just whatever string the person used to set it.
PROGRAMMER:
name changes:
o Renamed MFLAGS to MKFLAGS in makefiles to make gnu make happier.
o Split src/db/db.c in src/db/db.c and src/db/dump_db.c. db.c now
only has the in memory normal operation code. And dump_db.c has
the code for reading and writing disk versions of the db.
o GOD no longer exists. It's a variable named head_player which
defaults to #1, but will read from the db dump header.
GOD_PRIV has been removed, and is always on. This means that
you can't mess with head_player, basically. New macro
TrueGod makes God act more like Wizard wrt quell.
pure bug fixes & misc:
o Fixed large possibly fatal and dangerous bug in recycling code.
Also made it slightly easier to read.
o Fixed 'put' muf primitive to prevent writing one too far down
the stack.
o Fixed a bug with macros which don't have bodies.
o Changed a couple lines to allow source to compile under AIX again.
Pay the price of about 10 extra useless warnings under gcc.
o Removed a duplicated call to match_home inside of prim_match.
o Made string comparison routines in stringutils.c treat NULL as "".
o Fix problem with a '%' appearing at the end of a string in
pronoun_substitute.
o Fixed a typo in boolexp.c from '%1' to '%i' in an error message.
o Added a check for properties without names when loading a db.
o Removed all calls to perror.
o Changed all references to DOWNCASE to tolower and got rid of case.c.
o When a new object is created, it removes any program text for
that object number in the muf directory. This is normally
caused by a crash or such.
o Fixed some old code in LOG_FAILED_COMMANDS which used an old name
for a routine, preventing compiling. I guess no one uses this.
internal db structure changes:
o No more minimal_object structures. All objects use the same
general_object struct now.
o Removed the struct frame * and struct code * on the player_object
structure and program_object (respectively) making them identical
to the general_object structure. To keep track of the frames
for players a new file interp/frames.c was added. Similarly
interp/code.c tracks code segments for programs.
o Added support for placing boolexp's into properties. Placed
dbref locks into an internal property named 'Key', and removed
the old storage space on the general_object structure.
o Placed the struct prop_list directly in the general_object
structure instead of having it be a pointer.
ownership lists:
o Added ownership lists which are only used internally. You
probably don't want to use SetOwner anywhere now. Look at
chown_object.
o @stat, @find, @owned all now use ownership lists, and therefore
avoid full db scans.
o @entrances uses ownership lists partially, so it only does
one full db scan instead of 2. Still costs LOOKUP_COST.
disk db changes:
o New database header for the number of hash entries at
dump time.
o Changed database header reading to allow for missing fields
by using defaults, and to have it log any new headers.
o Sanity checker now checks player_start, global_environment, and
head_player.
cpu & memory changes:
o Fixed a major inefficiency in boolexp parsing.
o Slight change to the compression code to not do a separate
check for being compressed/uncompressed. This should provide
a very slight speedup.
o Fixed up timeout to select to be more intelligent. Now rather
than defaulting to 15 (which could waste cpu) it now picks
the minimum to next dump or rwho update.
o Hash table struct hash_entry's are now malloced in hunks
which saves a fairly decent amount of memory.
o Finally have small strings (<=63 bytes) be allocated in hunks,
much as other small structures have been for eons. This saves
on malloc overheads.
o Changed calls to FREE to FREE_STRING if the item was created
by one of the ALLOC_*_STRING routines.
o Removed the hash value and length fields on interned strings. Their
usage wasn't enough to waste the memory.
o Changed the compiler and interpreter to emit code in a manner
that is much more like real bytecode as opposed to '8 byte code'.
Reduces size of compiled programs to 5/8 of original size.
2.3 beta patchlevel 2:
----------------------
o Added a README file which might help those who get ahold of
the code not already knowing about it.
o Changed lockout.c so that the dbref field can now contain *.
This allows you to easily lockout everyone except for specific
people (such as wizards). An example of this was added to
minimal-db/data/lockout.sites.
o Added '-s' option to sanity which enabled the security check
option. Basically this will spit out what objects in your
database have flags set which might be security problems.
You might wish to save the output of this, and run it on your
db every week and checkout new objects that appear in the list.
o Changed @link so that objects can be homed to people in addition
to rooms.
o Updated the forth.ref and help.txt files in minimal-db/data
to be the same as the newer ones in docs.
o Added chown_macros command to compile/macro.c and changed
builtins/toad.c to call this to chown all player macros
upon toading.
o Added code to compile/macro.c to detect bad macro owners when
the display macros command is run.
o Fixed bug in interp/primitives file related to the number of
arguments returned by 'over' and 'depth' primitives.
o Fixed it so that non-wizards can't set or clear BUILDER or
MUCKER bits if RESTRICTED_BUILDING isn't defined or MUCKER_ALL
is defined.
o Added '+' (plussign) and '-' (minussign) cookies. Renamed
'amperstand' to 'ampersand' for '&' cookie.
2.3 beta patchlevel 1:
----------------------
o Fixed @open and @dig bugs which were introduced 10 minutes
before 2.3b release.
o Fixed muf property security hole allowing players to replace
other player's passwords with known strings. (Noticed by Adam
Wozniak).
o Changed Makefiles to notice when sub files were edited and to
rebuild everything properly.
o Added some items to Makefile and ansify.h for helping to port
to some additional platforms.
o Stuck more system specific signal ifdefs in interface/main.c.
o Cleaned up the restart script provided.
o Fixed up a few errant settings in config.h.
o Added edit_quit_external and interp_quit_external to make it
easier for servers to kick players out of the editor on
disconnect.
o Converter modified to work with daemonmuck and shadow dbs.
(Modifications by Ian McCloghrie).
o Added command line options to convert and sanity. (Added by
Ian McCloghrie).
o Added a sample lockout.sites to minimal-db/data.
2.3 beta release:
-----------------
The ''vanilla'' TinyMUCK 2.2 release is taken as the standard base for
the changes described here. The file old/CHANGES provides a historical
perspective on the development of 2.2 from TinyMUD.
