Changelog

#	$Old: Changelog,v 1.118 1998/02/24 18:30:16 mkb Exp $

1.1 -> 1.2 1999/03/12
	o do not expect getsid to be around
	o fixed a small printf-missing-arg bug
	o faciliated build a little

1.0 -> 1.1 1999/02/23
	o do not suspend if no login shell underneath
	o patches by Vadim Kolontsov included:
	   * bind on specified interface (-h argument)
	   * ctcp ping reports whether user or channel was msgd
	   * "transparent" colour for use with xterm/rxvt
	o fix for hash-compare induced command name ambiguity
	o a couple of user invisible modifications have been done
	  to a semi-critical region in hope to get rid of certain
	  crashes;  however, without a proper crash analysis, I
	  cannot say where the problem is exactly.  1.0 hasn't
	  crashed on me so far but did so for others.
	o the manual page has been extended by the new ircd 2.10
	  channel mode descriptions.
	o resizing on SIGWINCH didn't span all pages, fixed
	o fixed a bug when /msg tab-history omitted last character
	  of a 9-char dcc msg nickname

0.54-alpha -> 1.0 1998/10/20
	o note: an intermediate version (0.54pl2) has been around most
	  of the time between 0.54 and 0.55, fixing two of the ugliest
	  errors in 0.54 (as following)
	o Fixed iw_addstr() which caused memory corruption under certain
	  conditions
	o Fixed two bugs in the editor line input (^K and p when line empty)
	o Added televideo option (fucked up terminal support)
	o SQUERY and SERVLIST have been added
	o Fixed a bug in check_conf()
	o Replaced some "9" with NICKSZ where use of the macro had slipped
	  through; should now be better adjustable to servers with nicksize
	  > 9 chars (when limit raised appropriately);
	  ** Note before you flame me: this kind of stuff will all go away
	     in tirc2; no static limits of any sort will be used there **
	o Fixed a couple of minor stuff on the way
	o The overly formal tircbug script has been removed from the
	  distribution.  Send ordinary e-mail with a stack trace if possible
	  to the mailing list.
	o National character input (8 bit) has been fixed
	o User idle time has been pushed up to 7 days
	o The -d option didn't work anymore; fixed.
	o Oops.. I deleted the RCS tree sometime back
	o Thomas Koehler provided a workaround to compile TIRC on Linux/glibc
	  systems with broken SysV-IPC headers
	o Christian Bauer wanted to have ^N work as "next window"
	o In pastemode, TAB is no longer treated specially; this fixes a
	  rather large annoyance, when pasting something with tabs in it
	o Control codes (except those for inline attributes) are stripped when
	  adding a line to the window's buffer, this prevents that for example
	  an embedded TAB messes up the screen a little
	o A character between 128 and 160 (I can't remember which exactly)
	  is on few terminals equivalent to ESC; it hadn't been stripped
	  before because I didn't know of it, thus allowing an attacker to 
	  issue control sequences to the user's terminal.  The linux console
	  and some Amiga terminal emulator for example parse this control code,
	  xterm doesn't.
	  I haven't got the mail anymore from the person who noticed me of
	  that, so I can't give credits either but at least it's fixed now.
	o The hide-mirc-colours function (HIDEMCOL) should work as expected now.
	o The xterm title is now updated (if enabled) also when quitting from
	  the options editor (thus if you enable this option, it takes almost
	  immediate effect).
	o Check for vsnprintf, not for snprintf in configure (somehow didn't
	  work on hp-ux)

0.53-alpha -> 0.54-alpha 1998/02/18
	o Reviewed buffer sizes to use memory more efficiently on certain
	  malloc implementations
	o Rewrote iw_addstr() completely; clearer code now and might also
	  be a bit faster
	o rxvt is recognized as xterm-compatible when setting window title
	o Instead of unsafe sprintf/vsprintf, snprintf/vsnprintf together
	  with dynamic buffer expansion are used in vulnerable places to
	  prevent buffer overflows; on systems that do not have snprintf,
	  a bundled version is used.
	  This, together with the new iw_addstr() fixes a couple of
	  prospective and/or real bugs, like the "/help keys" bug in the last
	  version.
	o Moving the focus sideways in the option editor's colour lines
	  repainted the entire screen unnecessarily
	o Condition 3. of the previous usage and dist-license has been
	  removed
	o /abort has been removed (sending sigquit, usually with Ctrl-\ has
	  the same effect)
	o Some small fixes, modifications and optimizations
	o Fix: tty_getch() didn't check if characters read after Esc which
	  were (together with the Esc) not matched as a function key were
	  in fact a seperate function key string, typed before the Esc timeout
	  occurred
	o The editor line has been improved/fixed:
	  + The cursor is moved after the last character if changing to end
	    of line (C, c$, cw at end etc.) so that new characters get inserted
	    after the last character when typing
	  + X command didn't preserve line for undo, fixed
	  + Added cut buffer and pasting of cutted/yanked text with p/P
	    Text can be yanked with y/Y in the usual vi fashion
	  + named marks (m<a-z> `<a-z> '<a-z>) have been added; ' is the same
	    as ` here

0.52-alpha -> 0.53-alpha 1998/02/12
	o -lgen was missing from irix* LDFLAGS in configure.in, regcmp etc.
	  were not detected
	o Changed the tircbug utility so that it doesn't exit when it couldn't
	  run tirc to query the version (like if the build didn't work) but
	  queries the user to enter the relevant data
	o Added setlocale() call at startup which should fix some odd 8-bit
	  isprint() problems
	o Nickname completion adds a space character and colon if appropriate
	o Debugged the dynamic module code and made it work with the rest of
	  the client
	o DCC operations now check shared memory availability and cleanly
	  abort the pending operation (instead of exiting the program
	  in the generic chkmem()) if out of shared memory
	o The file ``Reference'' has been removed from the distribution.
	o Added nickname colourization based on approximate string matching
	o Moved some header files includes into tirc.h
	o Checks for presence of getrusage()
	o Recognizes generic svr4 in configure (for SINIX)
	o Enhanced security (checks length of server message etc.)
	o Added /set numerics, which when enabled displays a server message's
	  command numeric instead of "***", if it is tagged with one
	o Some outputs were not paginated (for example /set) and scrolled
	  past if the window was too small
	o Added the options & colour dialog ('o' in editor line command mode)
	o Minor fixes and modifications around the code
	o Fixed a bug with unitialized list links when only one element was
	  inserted in a tircrc-commands queue
	o Fix: client didn't grasp that server truncated an illegal nickname
	  (for example "foo.bar" to "foo")

0.51-alpha -> 0.52-alpha 1998/01/15
	o Merged in Rich's runtime-loadable module support
	o ':' in command mode enters insert mode and inserts the cmdch
	  at the beginning of the line
	o Added command line paste mode (^P)
	o The -d command line option didn't work anymore, fixed
	o STATS replies are now shown with the responding server name
	o ALIAS stuff doesn't show expansion when memorized and isn't
	  logged (safer against logs and curious bystanders)
	o Fixed small bug accessing previously freed block in iteration (in
	  delnamefromcache)
	o Regex storage now gets initialized with a dummy regex at startup
	  to avoid segv on certain buggy linux libc implementations
	o '`' (backtick) wasn't recognized as a valid nickname character
	o Fixed invalid memory reference in cmd_nonum(), when flregister()ing
	  a NICK message
	o A bug in listcucache() that overran a buffer in iw_printf() has
	  been fixed; this caused a hang on large /cnames output
	o Screen init has been moved further down in the startup sequence
	  again
	o Added the tircbug utility for problem reports

0.50.1-alpha -> 0.51-alpha 1997/12/12

	  0.50-alpha (should be practically leak-free again)
	o Added recognition of channel mode 'q'
	o Minor cleanups and modifications
	o Rewrote the editor line updating; it tracks the user's cursor
	  to provide enough context around what (s)he is typing
	o The prompt update handling now uses a better strategy aswell
	o The ``Porting'' file has been removed from the distribution
	o Fixed non-working alternate Unix name query at startup (if
	  config.guess couldn't determine a proper host type string)
	o Added help text for PARSE (debugging)
	o Fixed some wrong colourization

0.50-alpha -> 0.50.1-alpha 1997/12/06
	o Global rc file (/usr/local/share/tircrc)
	o Cosmetics: error msgs after screen init are printed as window
	  message, not to stderr
	o Bugfix: tty_rputs() buffer overflow with inline attributes
	o Bugfix: use of freed memory in iteration

0.49-alpha -> 0.50-alpha 1997/12/01
	o Bugfix in main.c, missing ',' causing K&R compiler to barf
	o Added checking for sig_atomic_t to configure.in
	o Added support for GNU regex (if no usable re functions and bundled
	  regex fails)
	o Fixed ellipsis syntax in some of the printf-style function
	  definitions' K&R part
	o Expanded macros using token concatenation (## or /**/) in source
	  since on SunOS 4, the preprocessor handled neither correctly
	o make lint works
	o lint run; fixed some bugs in K&R parts; removed unused variables
	  and some other glitches
	o editor line now isn't reset anymore (and history deleted) when
	  linking up to a server

	  or malloc); resized (smaller) some buffers (dcc buffer, screen
	  output buffer)
	o Added colour parsing and display
	o Fixed anomaly in tty_rputs(), concerning line wrap (attribute
	  control characters were not honored)
	o Fixed bug in dcc.c, causing use of freed memory if error on
	  control pipe caused entry to be removed
	o Removed nofmt global variable and handling (one side effect less)
	o Added UPTIME
	o Changed automatic aggregate initialization to static storage
	  class (since it is not supported by K&R)
	o Changed constant MAP_ANON to MAP_ANONYMOUS in mmap call
	o Tested on HP-UX 10.10 with bundled cc
	o Rewrote major parts of iw_addstr()
	o Removed some limits on statically allocated display format buffers,
	  (made them dynamically allocated), tested with 2000x1800 characters
	  terminal size (xterm)
	o Added '~' vi command (toggle case) to editor line
	o Bugfix: /query user wrongly said "No query in this window" (depended
	  on uninitialized data)
	o Slightly new face
	o Added bundled strtoul for systems where it does not exist
	o Bugfix: readrc() was executed before screeninit(), accessing
	  unitialized data on iw_printf()
	o Added immediate rc-commands and the "immediate" prefix
	o Added FAQ list
	o Cleaned irc layer initialization, removed small memory leak
	o Added aging of unaccepted DCC incoming requests
	o Added user selectable colour set (COLOUR command)
	o Bugfix: if $USER was not set but $HOME, it referenced invalid
	  memory
	o Added possibility of dumping backscroll to log when opening
	  logfile for window logging
	o Attribute control characters get stripped from log output
	o Fixed bug in dcc.c which sent "...request has been rejected" on
	  close even though it was us who initiated the request

0.48.1-alpha -> 0.49-alpha 1997/10/26
	o Refined checking behaviour of new mail check
	o Small error-print bug fixed in oodcmd()
	o Added quoting of cmdch ('/' by default) through // or /<space>
	o Bugfix shm.c: sysvipc segsize was initialized to 0 and remained 0
	o Bugfix cmd.c: $* expansion hung if no arguments were provided
	o Local in-address in dcc.c is now the same as used for the irc
	  connection, instead of trying to find one with the
	  gethostname/gethostbyname combination (this also works on systems
	  where gethostbyname() is lying)
	o ^_ (underscore) wasn't converted to digraph if attribs off
	o exptilde gets own home directory from $HOME if $USER is unset or
	  getpwnam() doesn't work as expected
	o Changed outfit a bit
	o Implemented DCC RESUME
	
0.48-alpha -> 0.48.1-alpha 1997/10/18
	o Fixed bug in done_urlfn()
	o Added URL to manpage

0.47.1-alpha -> 0.48-alpha 1997/10/18
	o help.h: ctcphelp wrongly said CTCP OOD instead of CTCP OP
	o manpage didn't mention Ctrl+X-O
	o moved basename()
	o Added the vi 'r' command to editor line
	o Notices to users on &channels (like &KILLS etc.) now get displayed
	  in the appropriate channel window
	o Fixed bug in irc_chrcmp() and some glitch in complete_from_ucache()
	  causing spurious sigsegvs
	o Replaced calls to strdup() with Strdup() since some systems don't
	  have strdup()
	o Next/previous page commands rotate now
	o SunOS 5 wasn't properly detected by configure and thus -lnsl and
	  -lsocket weren't added to the LDFLAGS
	o Added some more tests to configure.in
	o Wrote shared memory allocator
	o /dcc list now prints the peer in-address and how much data has
	  been transmitted (this uses the shared memory mechanism)
	o tty: added support for sgtty, tiocgsize
	o Ctrl+A, Ctrl+E behave now more like in real emacs
	o Fixed pagination bug in iw_addstr()
	o Tilde expansion is now done on all pathnames entered by the user
	  (dcc, logfiles)
	o '-' wasn't recognized as being a nickname character
	o Added wildcard support to op-on-demand uhost matching
	o Fixed a bug in ircx.c where iw_printf() was called wrongly
	o Added the URL catching mechanism
	o Bugfix: page update check indicator was nullified on screen refresh

0.47-alpha -> 0.47.1-alpha 1997/10/09
	o configure.in bugfix; ac_cv_prog_gcc was used before being defined
	o VOIDPTR macro, added test for void * in configure.in
	o Renamed TIRC internal function closelog() to ch_closelog() since
	  it collides with the syslog closelog() function
	o Made functions with variable number of arguments work with both
	  traditional and standard C
	o ctime() string contains a newline, this messed up the timestamp
	  display

0.46-alpha -> 0.47-alpha 1997/10/08
	o Linted
	o Bugfix: undernet, dalnet and even new efnet servers with a certain
	  patch send some server notices without a message prefix which tirc
	  couldn't deal with (eh, they should fix their lame server rather)
	o '^' and '_' were not recognized as nick characters in isnickch()
	o Added ChanOp-On-Demand facility (/OOD, /CTCP OP, /SET OOD)
	o Only first word in a ctcp privmsg gets converted to uppercase now
	o Minor cosmetics
	o '_' is now recognized as part of an alphanum word like in vi
	o Ctrl+T / Ctrl+X-O switch to previous window
	o $* in alias expansion denotes all arguments
	o Changed terminal attribute setting a bit; added tty_addbuff()
	  which adds a string to the output buffer without affecting the
	  cursor calculation
	o Added inline attributes like ^B == bold etc., converted source
	  to use them; when CONFIG_ATTRIBS is enabled, ircII character
	  attributes are not filtered out, resulting in the appropriate
	  terminal character attributes
	o Simplified v.h version string since NextStep cc (gcc 2.2.2)
	  choked on the composite defines
	o Changed channel mode display "+nt" to "+tn" because "nt" looks
	  a bit unpleasant to some of us
	o Server messages "End of blahblah" are not suppressed anymore
	  (although this is a compile time option)
	o Added 3rd alternative of hardcoded pgup/pgdn sequences, for use
	  with dec keyboard / xterm, DEC find key invokes search backwards
	o The NICKORPREFIX macro in irc.c uses the nickname if it's a valid
	  one or the server message prefix if the message doesn't originate
	  from an irc user
	o Notice to channels gets marked as such
	o Added /PARSE, to help in debugging server message handling
	o Using a Gnu Autoconf configure script for creating Makefile and
	  adapting source to the system environment; changed source to use
	  the results from configure
	o Bundled Henry Spencer's regular expression functions and provided
	  the possibility of using them
	o Added Spencer's and the University of California's copyright
	  statements to the COPYRIGHT file, since we bundle stuff from them
	o Converted everything to pre-STDC-like style (except some things
	  like enum, etc.) for better compatibility with older Unix systems

0.45-alpha -> 0.46-alpha 1997/09/11
	o Fixed error in help text
	o Handling of non-EOF server connection errors in doirc()
	o Bugfix: channelname was appended if privmsg arrived at topchannel
	  but in other page
	o Bugfix: empty lines got stored in editor line history
	o Bugfix: lastnick() was a bit inaccurate
	o More-prompts now scroll a whole page, not just one line
	o Bugfix in update_eline (signed interpretation of characters)
	o Bugfix: tab-reply to last privmsg was not cmdch-aware
	o Modified terminal scrolling with delete-line/insert-line
	  method, obviously didn't work properly before
	o Changed: DCC connection don't get closed automatically when
	  closing server connection
	o Ported to IRIX (5.3)
	o Changed to include <term.h> when configured with BSDCURSES,
	  since that file contains valid prototypes for tputs and tparm
	o dcc.c: changed some oddities with error handling in parent process
	o Bugfix: SIGWINCH only affected the first page
	o Removed small memory leak in backscroll regex matching
	o Fixed security botch with /tmp/lastlog (superuser could read
	  messages) by unlinking directly after opening
	o Fixed tty error handling in tstp handler
	o NICK/QUIT messages now favour the current page
	o Timestamps now contain date+time, as defined for the current
	  locale
	o User idle limit excession (client side) says so when exiting the
	  client
	o Changed quit behaviour (waits for server connection close)
	o If enabled, the status line shows a list of pages that have
	  received traffic since last visit
	o Added message logging, independent of lastlog
	o Added regular file checking in logging functions
	o Made movement in editor line more vi-like, revamped word movements

0.44-alpha -> 0.45-alpha 1997/08/12
	o The command line parser now accepts multiple commands, seperated
	  by a semicolon (`;') and quoted by "", except for message commands,
	  topic etc.
	o Implemented ALIAS
	o Added patchlevel indicator for beta releases in v.h
	o Fixed major memory leaks in regaddln() and iw_addstr().
	  According to the third degree atom tool, this dropped leakage
	  in an extensive testing session from 1.2MB to 500 bytes.
	o added free_history() to get rid of a fake memory leak at program
	  exit
	o added SAY, mainly for use in aliases
	o removed previously marked possible buffer overflow in screen.c
	  (strcat -> strncat)
	o Added emacs-like ^X semantics:
	  ^X-o switches to other window (like [ESC-]^W)
	  ^X-2 creates new window (/WIN NEW)
	  ^X-0 deletes current window (/WIN DEL)
	  And later ^X shortcuts for /PAGE handling
	o Added /LOG (channel logging)
	o Fixed clobbering of typed filename in logging functions if user
	  is asked for overwriting (same buffer), fixed sigsegv bug related
	  to this
	o All channels are now deleted when quitting irc, this ensures that
	  channel logfiles are closed and gets rid off a fake memory leak
	o Fixed small bug in iw_addstr() which caused lines to be wrapped
	  a bit too early
	o Bugfix: editor line messed up when typing if channel name in prompt
	  was truncated (longer than 20 chars)
	o Adapted to OpenBSD (2.1)
	o /SYSTEM -MSG routing output to target on irc
	o Fixed some /SYSTEM synchronization stuff
	o (xterm-)Window resizing (reformatting backscroll buffers according
	  to the new window width) is now fully operational 
	o Added nickname completion
	o Fixed bug creating stupid banmask in buildban()
	o Added /PAGE multiple irc pages
	o Revised nickchange oddities
	o Linted
	o Checked for memory leaks
	o Added xterm title change
	o Updated manpage

0.43-alpha -> 0.44-alpha 1997/07/09
	o Spooling outgoing dcc chat messages if writing to DCC socket
	  would block, this solves occasional blocking of the master
	  client if the remote side closed connection
	o Makefile changes: ``make third'' for ``third degree atom tool''
	  (memory leak & sanity checking on DEC Unix)
	o Implemented /query
	o ^W now only switches windows when in command mode.  This is
	  necessary since ^W is vi word-erase backward in input mode.
	o Fixed bug which kept dcc chat slaves running in busy loop
	o Fixed message/dcc chat history mechanism

0.42-alpha -> 0.43-alpha 1997/06/24
	o SIGPIPE is now ignored
	o Added handling for ERR_NICKCOLLISION and ERR_ERRONEUSNICKNAME
	o Implemented DCC CHAT functionality
	o DCC child processes usually don't exit on themselves anymore
	  but pause for the parent to kill them
	o DCC child processes terminate immediately if IPC to parent is
	  dysfunctional
	o buildban respects domain names with only a single dot and doesn't
	  try to ignore the entire toplevel-domain

0.41-alpha -> 0.42-alpha 1997/06/09
	o biff functionality (checks mailbox every minute) if enabled
	o DCC (direct client connection) file transfer is operational
	o Moved actual away/here toggling from cmd.c (user toggled) to
	  irc.c (server-reply toggled)

0.40-alpha -> 0.41-alpha 1997/05/22
	o Fixed silly thing in /nick (user couldn't change nickname
	  while not connected)
	o Fixed some non-critical bugs in update_cucache()
	o Backscroll buffers are now searchable with regular expressions
	  similar to vi(1)

0.39-alpha -> 0.40-alpha 1997/05/20:
	o Cleaned buffer-overrun on possible overlong user input
	  in getfromucache() 
	o Added ',' as a terminator for nicks for /op
	o Added clname support in the USER registration (though most
	  servers ignore this)
	o Cursor update behaves a bit differently (doesn't stick to the
	  editor line if it doesn't have to)
	o Wrote a manpage
	o Fixed a bug in 437 reaction (couldn't tell channel from nick)
	o Optimized editor line update to work better over slow network
	  connections or prehistoric terminals
	o ^U in insert/overwrite mode now deletes from cursor to start
	  of line, not the whole line as before

0.38-alpha -> 0.39-alpha 1997/05/14:
	o Fixed a bug in iw_addchan() which prevented deletion of
	  free()d channels from the channel list in certain situations,
	  corrupting the heap
	o Lint session, cleaned some minor glitches
	o Added keybindings quick overview help

0.37-alpha -> 0.38-alpha 1997/05/12:
	o Fixed a serious bug in getfromucache() which caused an
	  infinite loop if a nickchange resulted in the same nick
	  (character case change)
	o Minor cosmetics

0.36-alpha -> 0.37-alpha 1997/05/09:
	o Reacting on 437 if nick (ircd 2.9, nick/channel delay)
	o Fixed a bug concerning channel user cache and channel
	  deletion, added delchan()
	o Fixed display code reentrance in display_clock(),
	  which possibly caused occasional hangs
	o Added in-line buffer to prevent ping-timeout during
	  more prompts and in askpass()

0.35-alpha -> 0.36-alpha (inital change log) 1997/05/07:
	o TAB-reply history
	o ircd2.9-JOIN with modes (^G seperator) bug fixed
	o /umode command
	o /ign command
	o /desc command
	o /msg to channel displays like implicit privmsg to channel
	o CTCP TIME reply
	o USERHOST (/uhost) updates the channel-user cache
