Request diff between arbitrary revisions

* Add support for /ignore'ing a server (for undernet)
* Add --without-wserv flag to configure (see UPDATES)
* Add checks in configure for posix-like job control
* Add support so no job control -> no wserv support.

* Roll forward portability changes from epic4-2.10 (larne)
* This also includes term.h -> termx.h -- Make sure you rerun configure!

* Fixed q1cmd in command queues to address space mangling issues
  first noticed by Kraca.
* Fixed data_struct to work with dword.
* Fixed tabkey.ce to work better with args with spaces in them.
* Fixed tabkey.ce to not put / prefix on recursed commands (again).
* Fixed tabkey.ce to work with 005 CHANTYPES.
* Fixed $xdebug() to work with multiple arguments as it once did.
* Fixed what appears to be a typo in elf.c and I don't really know what
  it does.  I hope it doesn't break anything for anybody.  XXX
* Minor optimisation for notify.c.
* Added handling of the 340 numeric in numbers.c
* Handle extraneous spaces in server MODE messages.  Austhex adds these.
* Trigger waiting ISON's when we connect again.  I don't recall why
  I took this out in the first place.
* Added "/userhost -flush", which will flush the queue of messages waiting
  to be sent, NOT the queue awaiting replies.
* Extended "/ison -f" to also flush the queue of ISON's waiting to be sent.

* $info(o) now includes 'r' for libarchive, and 'x' for iconv support
* Unconditinally unset GREP_OPTIONS in configure (rb Pegasus)
* Fix /oper password being shown because term_echo() not called. (rb wjr)
* Properly handle multiple spaces between protocol tokens (rb Krisp)
* Fix crash with standard_warning_level() when you do /window level nonsense.
* Support /input "prompt" (args) {code}. See UPDATES. (rb kreca) (fusion)

* Add a server param to what_channel() so i can use it in send_text() later.
* Add length of 'meta' arg to ciphers so 'meta' doesn't have to be c string

Changes suggested by gcc-4.2.  No changes in behavior.

* Add arg to panic() controlling whether panic is sent via QUIT (rb black)

* Fix warnings found by gcc4 and run make depend.
* Add check for -Wno-pointer-sign to configure; makes using gcc4 less painful.

Various and sundry fixes, including allowing you to ignore operwalls.

* Fix valgrind bugs that nullie found (yay!)
* Fix bug with '' in the new math parser being NULL instead of empty string
* Add support for @#chan via notices to show up in #chan's window

Mental note: always compile with warnings turned on.

* Finish implementation of /stack push|pop set with symbol table, rb nullie.
* Preliminary work making @#chan public show up in #chan's window.

Attempt to fix the mode stripper.  I hope this doesn't bork.

* GC the fixed-alist support (last used by /quote and protocol handler)
* Reorg server SSL negotation stuff to be nonblocking. yay!
* Comment all sorts of stuff in ssl.c.

* Switch users of LEVEL_CRAP to LEVEL_OTHER. yay!

* Whack the 'highlight ignore' feature as per discussion on the list.

* Nix some func decls in windows.h that don't exist any more
* Add message_setall(), lets you save to_window on the message_from stack.
* Replace users of message_to() with message_setall().
* Replace direct users of to_window with message_setall(). yay!
* /XECHO got rewritten as part of this.  See UPDATES
* Fix various compiler warnings.

* Include <stddef.h> if we can, for no particular reason...
* Nix now unused mangle_line(). yay!
* Use (intptr_t) instead of (intmax_t) to treat pointers as integers...
* Try to handle failures from the dns helpers with more grace.

* Convert the other users of mangle_line() to new_normalize_string (*gulp!*)

Addendum to the previous commit.

The /ison changes were difficult to separate and aren't documented:

These are the -e, -end and -max flags, and the fact that -max and -len
are per-server variables now.

Reorganize how nickname changes are handled, refactoring coming soon!

GC a bunch of stuff no longer in use.

* Change /on leave to /on part.
* Only ever do one io event per call through select() or poll()
* Do put_echo() and not add_to_screen() in /window echo so it can be logged

* Round one of blackjac's 'builtins' script.
* Comment out a ton of now-scripted sets.  Will GC it later.

* Keep timestamps along with lastlog entries.
* Add $line(<num> -TIME), return the timestamp when <num> was added to lastlog.
* Remove some #define's from config.h that are not referenced any longer.
* Remove #define QUIT_ON_OPERATOR_KILL because 1 line of script defeats it.

* Refactor window_check_servers() to work with server's current window only.
* Roll forward all the rest of changes from epic4 (i think)
* Add /ON NEW_NICKNAME, when epic needs a new nickname from you.
* Run 'make depend', fix compile errors, fix 'environment' script

* Numerous new and changed features as per UPDATES.
* Better handling of damaged /who x,y responses.

GC a bunch of useless cruft and stuff.

* Make sure that servers go through SERVER_EOF state on eof!
* Track waiting/pending channels using a nicklist per window.
* Nix $winbound() and all the other stuff relating to bound channels
* Fix bug with binding/initializing the 255 key
* Fix bug with TOGGLE_STOP_SCREEN keybinding.

Well, at least it compiles again, but I think i still need at least one
or two sweeps of the code to make sure I got everything proper.

*********** DONT RUN THIS -- IT'S WORK IN PROGRESS -- DONT RUN THIS ***********
* Import epic4 commits 674 through 692, inclusive.
* Import epic4 commits 693 through 710, inclusive (epic4-2.0 final)

* Add add_mode_to_str() which adds a channel or usermode to a string (sorted)
* Make usermodes use add_mode_to_str()
* Make channel modes use add_mode_to_str()
* Now modes are not stored in bitmasks, not hard-coded at compile time. HUZZAH!
* Nix "inactive" field in channels, channels are thrown away at disconnect
* Don't allow channels to move between servers, natch.
* Nix all the code to handle disconnected channels and such.

* Check /set auto_rejoin_connect at disconnect-time, instead of connect-time.
* Use a "is_server_active()" function instead of "did_server_rejoin_channels"
* Move the guts of got_initial_version_28() into server_is_registered()
* Call "server_is_registered()" from 001, which loads ircrc among other things.
* Reduce 004 so it only sets the server's version string id.
* Nix got_initial_version_28

Make 'empty_string' (const char []).  Now we're cooking with gas!

* Nix /set beep_when_away, a 1-line scriptable feature.
* Add new noise level %, (/ON %TYPE); like ^ but doesn't turn off display
and other stuff as well.

Make message_from() work off of a stack; use panics to guard against
unmatched message_from()s, and other wackiness.

* Hook in $windowctl(), just for fun for now.
* Enclose a few more dcc outputs in the target nick context.

* Valgrind is my hero -- fix buffer underruns with mangle_line().
* Make the "current input window" its server's current window on user input.

* Numerous updates/changes/fixes to DCC, functions, scripts, /EXEC, the
  new math parser, as per UPDATES and KNOWNBUGS.

One potential incompatibility is in the change to $open(). (as per UPDATES)

RFC1459 says that protocol commansd have 15 arguments *in addition to*
the command.  Fix an off by one error.

Fix /set mangle_inbound

Fix it so you can compile on systems without (intptr_t) again.

* Revert all uses of LOG_CURRENT to LOG_CRAP
* Change all uses of message_to(0) to message_to(-1)
* Fix show_help() to not change to_window, it doesn't need to care about that.
* Fix help_put_it() to not change message_from, doesn't need to care about it.
* Fix /lastlog to use message_to(0) to send all output to current window.
* Don't make output of /log go to current window -- no point to that.
* Teach add_to_screen() to honor from_server's current window for LOG_CURRENT
* And for /set current_window_level as well
* Fix message_from() not to save/restore lastlog level, doesn't need to care.
* All of this pretty much nukes LOG_CURRENT except for /window, HUZZAH!

* Fixed the ENCRYPTED_PRIVMSG/NOTICE hooks to append the decrypted data
  as before.
* Turned the umodes setting on again (set by the server in the 004(?)
  numeric and accessible in the client via $serverctl([gs]et umodes).
  I need to talk to people who have difficulties with this.

* Fix buffer overrun crash with CTCP UTC.

Make some compile warnings go away by using (intptr_t).  I hope this
doesn't bite me -- every system I checked has (intptr_t)..

Cut over m_sprintf() to malloc_sprintf().

* Misc bugfixes as per KNOWNBUGS.
* This patch involves renaming crypt.h to sedcrypt.h.

* Rename 'dcc()' to 'dcc_cmd()' so we can use dcc as variable
* Garbage collect unused 'irc_path' global variable.
* Add --with-warns to configure to do FreeBSD "WARNS" like compiler checks
* Many hundreds of changes to improve the "quality of code" in epic, including:
* - Treat all literal strings as (const char *) and fix const correctness.
* - Mopping up all remaining const-correctness issues
* - Do not "launder" a (const char *) to a (char *) in string searches, (ala
    strchr) but rather return a ssize_t offset value.
* - Particular, MatchingBracket() returns (ssize_t) and not (char *).
* - Eliminate all "shadow" variable names by changing them to something else.
* - Eliminate most function decls that do not include a prototype list.
* - Add prototypes for all extern functions that are missing them.
* - Ensure most function pointers include a prototype list.
* - In term.c, most of those (char *)'s are really (const char *)'s.
* - Explicitly specify 'static' functions as 'static'
* - Ensure every function is either 'static' or has a prototype.
* - Eliminate (unsigned) < (signed) type comparisons.
* Hopefully you should not notice any changes!

* Nix checks for stpcpy() in configure -- regen configure.

* New /set, /SET SWITCH_CHANNELS_BETWEEN_WINDOWS
* C language issues (const correctness, integer size correctness)
* Revamp channel structure to hold window refnum and not window pointer
* Add "current channel counter" to channel structure.
* Determine "current channel" by election.

Yikes.  Merged to become consistent with HEAD.  Sorry for all the commits,
I'll be quiet again soon. :)

Commit 437

* Fix targets not being assigned correctly for privmsgs to user.
* Send output of who replies to LOG_CRAP as per previous behavior.

Commit 436
This commit is deceptive because it is huge in scope but can be explained
pretty simply.

* Const correctness improvements.
* Invert the meaning of 'new_check_flooding' to return TRUE if flooding.
* Revamp funny.c, /list, /names, /mode reply handling.
* Remove unused joined_nick, public_nick
* Change got_initial_version_28() arguments singly and not an array
* Change signature of protocol handling to take "command" as an argument
* The above change cascades to a lot of other changes.
* Allow the /msg'ing of @W<refnum> to msg a window's refnum.
* First round of larnification (Protection against unexpected server data)
* This involved substantial rewrites of parse.c, and numbers.c
* Now "fake" stuff goes through /on odd_server_stuff.
* Fix /on invite so it takes 3 arguments, not 2.

* Use server_list_size() and not number_of_servers outside of server.c
* Use NOSERV and not -1 for "no server"
* Use (Timeval) and not (struct timeval)
* Fix (get|set)_server_sent_*() et al to take server refnum.
* Use parse_server_index() and not my_atol() to parse server refnums
* re-indent quotecmd
* Rename is_server_connected() to is_server_registered
* Make /quote work as long as server is open (not registered)
* Use send_to_aserver() when it can avoid setting from_server unecessarily
* Change sent_to_server and clear_sent_to_server to (set|get)server_sent().
* Change doing_* to get_server_doing_*.
* Use (unsigned short) and not (u_short)
* Use (unsigned long) and not (u_long)
* Make output_reject_ctcp() take a refnum
* Lock a dcc while we are connecting it, just in case. ;-)
* Fix /dcc send -p <port>
* Store protocol enforcements as (get|set)_server_protocol_state().
* Use (Stat) and not (struct stat)
* Rewrite $timerctl() so it works like $logctl()
* Rename is_server_connected() to is_server_registered()
* Fix an off-by-one error with /FOR ... IN ...
* Keep track of both readable and writable fd's with newio stuff.
* Convert server_list to an array of pointers
* When user /server -delete's, leave a gap, don't change refnums around.
* Nix code that handles deleting server refnums.
* New function, new_open_for_writing(), for when we do nonblocking connects.
* Change new_open() to deregister fd as "writable"
* Renovate the notify stuff to take refnums and not just use from_server.
* Renovate /WHO, /ISON, /USERHOST to take refnums and not just use from_server.
* Make everything that uses server_list[] use get_server() instead.
* Make everything capable of dealing with "gaps" in server_list[].
* Use a bunch of macros, to handle with getting and setting server attrs.
* Make as much as possible use refnums as params and not from_server.
* And a lot of other stuff...

* Added functions $asciiq() $chrq() $exec() $timerctl() $tcl() $winline()
  and $floodinfo().
* Altered the two argument version of $read() to ctcp quote the strings it
  returns.
* Added sets FLOOD_RATE_PER and FLOOD_MASKUSER.
* Altered the "accept" mode of the dcc_raw and dcc_connect hooks to refer
  to the local port instead of the remote port.
* Added a "-closein %proc" switch to /exec.
* Altered the arg list mode of /alias to use extractw instead of next_arg.
* Added the documented "words" argument to the above.
* Tuned autoget, mudirc, tabkey.ce and commandqueues.
* Altered /pretend to not chop the string.
* Set about rewriting the flood detection and then decided that it's better
  off being a script.
* Moved the function macros to their own file (functions.h) and replaced
  all the copies that are strewn throughout the source with an #include.
  The exception is array.c which broke when I tried it.
* Moved the ctcp enquoting/dequoting functions to ircaux.c.
* Added some command/function ordering checks to funcs/regress, and a check
  for all the functions that are undocumented.
* Rewrote function chanmodetype() so that it doesn't have all those flakey
  buffering things.  Hopefully it's readable now.  The significant change
  is that if a mode character appears twice in CHANMODES, the first one is
  returned instead of the last.
* Added EPIC::call() in the perl routines and an equivalent under tcl.
  this is designed to call a $function() directly, but it isn't really that
  fast, so I might rip them out again.
* The /wait internals used to store a few other settings, which were taken
  out, so I put them back.
* Fixed a few problems with normalize_filename() around the place.
* Fixed a bug with /timer in which it would never show the timers after a
  callback.

* Change do_input_timeouts() to a timer callback.
* Nuke the now unused global /wait stuff
* Revamp timer.c so you can add/change/delete/update timers during a timer
* Change add_timer() so it takes a winref not a window pointer.
* Make the "key timeout" thing happen on demand instead of a recurring timer
* Remove the recurring "key timeout" timer.
* Remove the 'key timeout' thing from io(), also 'first time' stuff.
* Call get_time() after select() in io().
* Fix two compile bugs found by larne.
* Fix bug when you did /flush on a /clear window.

Added a fix for $: and $; (last joined and last public message).

Note:  I didn't take out the code for the old method of generating these
       variables.

Another round of epic5 changes...
* Make $B, $., $,, $:, $;, $I, /WAIT stuff server specific, from epic5
* Make tracking of doing_(privmsg|notice|ctcp) server specific, from epic5
* Fixes for Const Correctness.

Cleaned up a few -Wall warnings.

* /exec leak fix for -line, -part, etc.
* /for var from x to y step z will work for negative z now, but for bug
  compatibility, you must use a negative step to actually make this work.
* Local variable tweaks.
* Fixed $word() to not discard words after a "".
* /userip now uses the internal queue, if the server supports it via the
  USERIP 005.  Otherwise, it will send the command directly to the server.
  The problem with this is that to avoid the internal cache returning the
  users address, you must use -direct.  This needs to be fixed.
* Karll Array overhaul.  Removed certain performance traps for very large
  arrays, which have very large numbers of like items, and made it such
  that arrays can be in an unsorted internaly until the time that they
  need to be sorted, when a quicksort is called on them.
   * Added two new functions to deal with this:  $usetitem() and
     $delitems().  These work like their similarly named counterparts, but
     leave the array unsorted, and generally perform better.
   * Any function which uses indexes or performs a binary search on an
     array will cause the array to be sorted.
   * For the most part, extended functions to allow for additional
     item/index args.  $getitem(array $getmatches(array *cat*)) will
     return the contents of all items that have the character sequence
     "cat" in them.  $getitem(array2 $getmatches(array1 *cat*)) will
     act much like $copattern().

Fix $ischannel() (actually, is_channel()) to return 0 if a NULL or
empty_string is passed.  Also fixed a typo inre serverctl comments.
-wd

* Added support for CHANMODES, PREFIX and CHANTYPES in the processing of
  modes.  If the server doesn't support these, then hopefuly sane default
  strings are chosen, and these _don't_ include the wacky extensions that
  have been added over the years, so conceivably, this could break things
  like halfops and ban/invite exemptions.
* Stored the UMODES field from the 004 numeric in the server data.  Can be
  retrieved with $serverctl(get x umodes).
* Altered "/msg @$fd" so that $fd must be a number, otherwise, it will be
  treated as a privmsg.
* Added $xdebug() which returns all single bit flags with + or - added as
  appropriate.  /xdebug $xdebug() is a no-op.
* Fixed an /xdebug bug in which - would cause all subsequent flags to be
  switched off.  For bug compatibility, it still works this way, but you
  can specify + to turn all subsequent values on.
* Altered m_sc3cat_s() to call m_sc3cat rather than m_c3cat, which results
  in a cleaner string.  Examination of the uses of this function showed
  that they all dealt with this bug in some way.
* Altered $which() to call path_search() directly, rather than uzfopen().
  It may be useful to add a flag to path_search indicating which attributes
  we are searching for.  This could cause problems since the old method
  would skip over a file if it wasn't readable.
* Added clue variables for $unsplit().

Update copyright notices and copyright dates.

* Applied a patch from NSX which fixes a problem with the last commit that
  prevents the inital server connection working.

Other things also commited:
* Fix for ODD_SERVER_STUFF so that it will never have a blank server field.
* fixed $chr() to not have input size limits, however it still cores on
  random data.  I'll fix this later.
* Fix for get_time() in the case of HAVE_GETTIMEOFDAY being undefined.  I
  forget who this was from.
* Minor method addition to tabkey.ce.

Due to the way the new attribute parser works, mangle_line needs a destination
buffer that is at least eleven times as large as the original string.  Change
all uses of mangle_line to pass in 11 times as much as necessary.  This avoids
uneccesary truncation of input lines with excessive attribute changes in them.

No functional changes, just removal of unecessary whitespace at the end
of lines.  From adm.

Add some larneproofing.

* Fixed two compiler warnings that apparently occur under macos X.
* Altered "/ignore #channel crap" to work for quit messages.  The rationale
  behind this is that "/ignore #channel nick" works, and the code for both
  are very similar.  This may conceivably alter the exact behaviour of
  channel_signoff, but I have made efforts to keep it working as is.

* Enhanced flood checking to keep records based on userhost rather than
  nick.  Not designed to catch clones but to make it harder to avoid.
* Flood checking keeps its time in microseconds now, which _may_ make it
  a little hyperactive on occasions.
* Small re-arrangement to find_array_item() to make it slightly faster.
* Terminology fix in /alias /s.
* Added $regmatches() which works exactly like $regexec, but returns pairs
  of numbers which can be applied to $mid() to extract the matched strings
  and substrings from the original string.  It also takes a new second
  argument indicating the maximum number of subexpressions to return.
* New -file option to /lastlog.  If given, all output will be written to
  the file rather than the screen.  file_put_it() may be questionable.
* $channel() will return "h" in the op field if the user is a half-op.

* Bug fix:  *shoot me*  $encryptparm() wouldn't check if the program field
  was empty before sprinting it.
* Failed received SED messages make their way through encrypted_privmsg and
  encrypted_notice now just like the successful ones, only without the
  "[encrypted message]" message.  The reasoning is that first of all, it
  should be possible to block these messages and secondly it makes it a lot
  easier to script a secure key exchange.  The failure hooks are called with
  only two arguments (no message).  This may be a bad idea.  On the one hand
  it makes it easier for a script to catch, on the other, the hook looses
  certain critical information.

Reset the "sed" global to 0 at the beginning of every PRIVMSG/NOTICE.  This
may be slightly inconsistant with design in that it seems to be only reset
at the end, however, there are also a few exit points that break with
consistancy, and this just seems to make more sense.

Ok.  ESR asked us to change our manpage.  Some of his changes worked,
some of them did not.  I took the ones that did work.

Add /on general_notice and /on general_privmsg.  These will be documented
in UPDATES -- they are generalized versions of /on (msg*|public*) and
/on (notice|server_notice).

Break backwards compatability on /on ctcp_reply by changing $*
	$0	Sender
	$1	Target		[new]
	$2	CTCP command	[Was $1]
	$3-	CTCP Arguments	[Was $2-]
Everyone i asked wanted this change, so i claim immunity.

Add channel mode +M support, for dalnet.
This also includes the actual use of the previous commit, which
implements /set auto_rejoin_connect.

Use "safe_new_next_arg" isntead of "next_arg" in any argument that you
pass to a printf function, d'uh!

It would be better if publics didn't go to LOG_MSG, mkay?

Commit #34 -- in /on error, include the server name as $0.

Commit #29:
* Add /on error, to handle ERROR protocol messages.
* Fix /window * toggle, to actually toggle.
* Add /defer command, per email on epic list.
* New hybrid6 script from is-.
* Fix a bug with strlcat() from openbsd via freebsd.
* Axe long broken "1 second cursor in window" delay thing.
* Repeal the "deferred free" stuff in 0.9.15-10 that wasn't too good.
That's it!

Stage 2 -- what am i getting into?  This is the second stage of the server
connection closed coping mechanism.  This will be tested, bugs may ensue!

Add a "reconnect_to" feature to the servers.  The idea is that instead of
closing the server when we recieve a 465 or 010 numeric, instead we should
stash the refnum of the server we want to connect to in the server's data,
and then when we recieve the EOF from the server, at that point do the
reconnect.  This saves users pain and suffering when there is important data
after those numerics.  Thus, we only ever drop our connection to the server
when the user does /server + or /server -.

Commit #11 -- support efnext's 010 numeric (Please use another server)
Support dalnet's +O (elite bastard only) channel mode.

Ok.  So i'm a doofus.  Replace && with ||.

Support Unreal ircd's unreal gratuitous breakage that results in them
sending a void mode change to the user upon connect.  This violates the
protocol twicewise and whoever came up with this deserves to be drawn and
quartered and then burned at the stake.
