are being stripped.

Just update a bug i forgot to mention i fixed.

Fix $logctl().

* Fix color bleeding with color changes in middle of long words that wrap.
-- This was reported by blackjac.  It's a bug that occurs if you do a color
change in a very long word that ends up wrapping to the next line.  If there
are no more attribute changes ni the next line that it wraps to, then the
line after *that* (the third line) will get the attributes at the end of the
1st line instead of the attributes at the end of the 2nd line.

* Fix compile warning for alloca on freebsd-current for blackjac. bleh.

Flush all of the small bug fixes i've been sitting on.

This should NOT have been commited.  Back it out.

Add /xecho -f for howl
Add a timer dump for "stuck in a polling loop!"

Fix many errors using realpath() and normalize_filename().

Fix my_realpath() for linux users.

THE LAST CHANGE -- I REALLY MEAN IT THIS TIME.

EPIC4-2.0 passes its vote of confidence!
* Fix a bug with /window channel frobnitz hide doing a null deref
* NSX asked for one more change under the wire.

The nick list in 353 is not mandatory.  IE:
	:server.name 353 mynick = #chan\r\n
is perfectly acceptable.

Fix bug with history expansion when there is a line with only /'s in it.
Reported and fixed by |Rain|.

Fix $-at-end-of-string null deref (/echo $($))

Try to fix %\\ and *\\ for zinx's official objection.
I hope i hope i hope i hope i didn't break anything else....

* Fix /WHO arg handling.  The old code was crap and wouldn't do /who -oper

New script, 'urlgrab' from wc.  Thanks!

Script changes from howl and nsx, as requested.

Fixes and new features as per KNOWNBUGS and UPDATES.

* Fix bug with nicks ending with \ in the 353 numeric which has trailing space
* Auto-close DCC's that can't send handshakes due to family mismatch.

Miscelaneous fixes and features as per UPDATES and KNOWNBUGS.

* Fixed $shuffle*() to respect extractw.
* Altered $rest() so that a negative first argument makes it a compliment to
  $right() in the same way that a positive arg makes it a compliment to
  $left().  This may conceivably cause problems for scripts.
* Spruced $joinstr() up a bit.  It now accepts any number of variables and
  respects extractw.
* Fixed an extractw bug in malloc_strcat_word_c while testing the above.

* Added $splicec() in functions script.
* Added /set dcc_dequote_filenames.  Perhaps this should default to off?

Allow semicolons in the middle of the switch command.

Change default of /SET AUTO_REJOIN to OFF.

Fix for meta-compat, from rain.

* Make inet_vhostsockaddr() extern so dcc can use it
* Make dcc_open() use inet_vhostsockaddr() to bind /hostname to dcc conns
* Don't allow -b and -q, or -b -and -s, as they cause deadlocks/panics
* Fix casting error that caused $urlencode() of high bit chars to segfault
* If swapping in a window that has no room for double status, recalculate all
* If double-on in a window that has no room for it, recalculate all

* Fixes to 'less' script from howl
* New 'help' script from howl
* Add /WINDOW SCROLLADJ.

Fix some more problems in the pf loader.

* Add /ON WINDOW_BEFOREKILL
* Another iteration of the 'notify' script, hooks the system's /ONs now! =)
* Put a space in place of a newline in the PF loader.
* Always ignore spaces after semicolons in parse_line (the {} parser).
* Some compiler warning fixes from rain.

* Do not increment arg_count when ignoring an empty argument in arglists.

* Make the output-window-searcher ignore from_server for LOG_DCC
* Make status_hold and status_hold_lines use scrollback numbers too.
* Make add_to_scrollback() redraw status bar if output while scrollbacking.

* Fix DCC events so that they occur in the context of "no server" (FROMSERV)
  rather than the "current server" (NOSERV).  This can fix or completely break
  certain intermittent scripting problems.
* Fixed {f,}q1cmd in commandqueues so that it works properly in the "no server"
  context.

Fix some issues with $numlines()

* The last argument to open_file_for_write() needs to be lowercase.
* Add $numlines() from fudd.
EPIC4-1.2.3!

* Fix /window kill so it doesn't swap in a window too early.
* Make NOTICEs from servers to channels (on ircnet) go to that channel's win.
EPIC4-1.2.2!

* Fix /window next, /window prev (SWAP_NEXT_WINDOW/SWAP_PREV_WINDOW) to
  skip non-swappable windows.

* Add /SET STATUS_NOSWAP
* Fix #define DEBUG_EXTRACTW_DEBUG/LASTLOG
* Add -o and -O command line options to turn off IEXTEN termio() options
* Add /WINDOW SWAPPABLE (defaults to on)
* Add %{1}W status expando, expands to /SET STATUS_NOSWAP if SWAPPABLE OFF
* Don't allow windows to be swapped in or out if SWAPPABLE OFF
* Don't allow windows to be shown or hidden if SWAPPABLE OFF
* Do allow windows to be swapped in with WINDOW KILL even if SWAPPABLE OFF
* Add $windowctl(GET <refnum> SWAPPABLE)

More compiler nits fixed.  Nothing worth fretting over.

* Fix a couple of minor compiler nits
EPIC4-1.2.1!

* Fix a NULL deref if you do /window when there is no current window (!)
* Update notify script from nsx, add sping script from nsx.

* Fix the larneproofing in numeric_handler(), it was defective all over.
-- Reported by jb.

* Update tabkey.jm one last time
* Add 'notify' script, a replacement for the notify command.
* Fix $windowctl(GET <refnum> DOUBLE)
* Make /on window_command give two refnums, the before and after refnums.

* Add $windowctl(GET <refnum> DOUBLE)
* Support inbound double quoted filenames in dcc handshakes. bleh.
* Fix NULL deref when you kill hidden windows (ie, /window killswap)

* Fix raw listen DCCs not obey /SET DCC_TIMEOUT.
* Added outputting of long long ints to new math parser.

(*gulp*) Some changes for fudd.
* Add /ON WINDOW_COMMAND, hooked after every /window command, $* is refnum.
* Add concept of "fixed" or "frozen" windows when you SKIP ON FIXED ON
* Fix /window kill to not kill the last "non-fixed" window
* Fix /window hide to not hide the last "non-fixed" window
* Allow /window kill to kill a "fixed" window, but not the last window.
* (*gulp*) I hope all of the above works!
* Fix $windowctl(REFNUM ...) it was out of order with REFNUMS
* Make /xecho -l override the "who_from" target and always send to the level

Document $windowctl().

* Fix /lastlog <number> for kanan.

More complicated atoll() replacements.

Unconditionally do (long long) integer math in the new math parser if
your system supports (long long).  I suppose on some systems this will
make math slower, but that seems like a small price to pay for having
integers that will actually support IP addresses!

$info(o) will inclue the letter 'l' if the host client is working with
64 bit integers in the new math parser.

Please note that the old math parser has not changed, and still only
supports 32 bit integers, and that won't change for backwards compatability.
If you really really really need 64 bit integers, think about changing to
the new math parser.

Changes agreed to in principle by: ce
* Make /server <host> honor server groups if can't connect to <host>
* Make reconnects use the server group of NEW server not OLD server.

Fix typo that broke /notify on servers other than server refnum 0.
Broken in commit 403 (Dec 19, 2002).

Fix typo after i told nsx the bug couldn't possibly be becuase of a typo.
(nsx found the way to reproduce the bug so he did all the hard work here)

* Fix /window query, it was a victim of larneproofing.  Ooops! (Bugref 6)
* Hook in $windowctl(), just for fun for now.
* Enclose a few more dcc outputs in the target nick context.

* Fix a possible logic hole in ok_to_output()
* Fix memory leaks found by valgrind.

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

Implement infinite recursion detector and thwarter.  It requires a #define
in config.h, the future of which I have not decided yet.

EPIC4-1.1.15!

From previous commit...
* Fix urldecode
* /lastlog -msgs 3 is obliged to skip back 3 msgs, not just 3 lastlog entries.
* Fix warnings in gailib.h

From this commit...

* Fix uninitialized variable in ok_to_output() that caused panics.

See KNOWNBUGS

* Fix panic with $joinstr()
* Fix compiler warning comparing pointer against integer
* Fix word appender to NOT USE DOUBLE QUOTES if /xdebug extractw is off!
* Fix the word appender so it actually works right.

* 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)

Add /who -operspy for hybrid opers.

Add sanity checking to avoid cross-family dcc problems, where we bind() a
listening socket in one family and send out a dcc handshake for another
family.  Oops!  Noticed by rain.

Add /on dcc_activity, a hook for scripters to create a %D-workalike.

* Add /set wserv_type, either "xterm" or "screen".
* Add malloc_strcat_word_c, add a single word to word list, with "" support
* Convert a bunch of stuff to use malloc_strcat_word_c to honor ""s right.
* GC a bunch of unused code.

Commit 610:
* Use the server's message in our default 330 output.
* Make $numwords() use count_words() as a test.  Looks ok so far...
* Make $indextoword() use count_words().
* Implement regression tests for $indextoword()
* Any further problems with $indextoword() should add regress tests!
* Make epic behave like ircII when doing /window create with screen and X.
* Make move_to_next_word() stop when it hits a trailing nul, duh!

* Work around "(brown paper bag release)" version in 004 in ratbox-1.2-3

the command.  Fix an off by one error.

* Allow $serverctl(SET <refnum> UMODES)

EPIC4-1.1.13!

Commit 600 -- Huzzah!
* New tabkey.jm script from nsx.
* Set the window's waiting channel before sending out the JOIN
* Let <pagedown> and <end> work on hold mode as well as scrollback.

Make sure message_from() gets called properly before a /dcc chat message.

Fix UNSTOP_ALL_WINDOWS keybinding, rb ce.

Implement "privleged yells" which allow syou to do /set debug 7 at the
same time as /set output_rewrite.  Yea~!

* Add $servernick(<global>) to return the client's global nickname
* Update tabkey.jm to latest version
* Add new ircII-compatable /window hold_mode thingee.
* Add /set hold_slider, /window hold_slider

* /XEVAL -- ends eval option processing, like how /xecho does it.

Fix $servernick()

Fix /set mangle_inbound

Add $servernick(<global>) which returns the client's global current nickname.

Fix the {...} expression parser operator to not infinite loop when it
can't find the $FUNCTION_RETURN local variable.  Umm, yea.

Fix panic caused by accidentally allowing the user to /server -delete all
their servers. (fix is to not allow them to delete the last server)

Fix it so /set mail 3 and /set mail 4 don't cause panics.

Nominally allow someone to do:
	/dcc rename <nick> <file> <absolute path>
for example:
	/dcc rename hop alias.c /usr/home/jnelson/foo/alias.c
which acts as a "per-dcc" store path.  Normally files are stored in your
/set dcc_store_path unless you /dcc rename them to another absolute path.

I do not know if I broke anything doing this.  Let me know if you see
anything odd.

Make ^ and ~ equivalent since all irc servers do already...

* Fix /on ctcp_reply so it hooks in the LOG_CTCP context. (rb nsx)

* Make /window swap update the current-window-priority thingee.

* 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!

Include <stdint.h> and <inttypes.h> if they exist.

Fix bug 5 -- panic when you do $push(:foo   ) [and $unshift() too]

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

Add nsx's 'tabkey.jm' script.

Fix a really stupid bug I made last night.  :/

* Fix $<num> to not have leading or trailing spaces, cause zinx said so. ;-)

Fix some bugs that can be attributed solely to a total lack of testing
on my part.  I'm rather embarrased about this.

Teach all the /set callbacks to take a (const void *).
This fixes a bad-c problem with /set!

* Add set_float_var() to set the 'number' field in a set.
* Teach set_variable() about FLOAT_TYPE_VAR sets.
* Teach save_variables() about FLOAT_TYPE_VAR sets.

* Modularize/reorganize mail checking, with mbox reference implementation.
* Automatically /set mail 0 if the user's mbox can't be found.

Maybe I fixed a bug, maybe I didn't.

Commit 556
* Change #define DEFAULT_CPU_SAVER_EVERY to 60, it needs not be 0.
* Create 'clock.c', to hold clock generation, system timers, cpu saver watchdog
* Create notion of "sys(tem)timers", callbacks for mail, notify, clock gen.
* Add 'system_timer', generalized callback for all of the system timers.
* Fix add_timer() so the 'command' argument does what the docs say it does.
* Extern 'timer_exists' so we don't try to remove_timer() and invalid timer
* Redo dependancies because clock.h exists.
* Add code to bootstrap mail systimer with /set mail

* Make remove_timer() an extern function so i can delete timers. ;-)
* Add /SET CLOCK_INTERVAL and /SET MAIL_INTERVAL

* Reorganize the clock generation stuff into "reset_*_clock" functions
* Generate the clock statically; only update it from the CLOCK timer
* Add reset_system_timers() which regenerates all four system timers.
* Don't set system timers in main, call reset_system_timers() instead.
* Don't enforce "notify interval" in do_notify(), handle that in NOTIFY timer.
* Comment stuff in words.c

Fix up /load to honor the /return command so you can abort early from
within a /load'ed file.  See 'pf-loader' for details on why you would
want to do this.

* Fix bug where $<num> (as the last word) would chop off the last character
* It is necessary to remove trailing spaces for $<num>, historical practice.

Commit 552

  ignore.  This was specifically asked for, but I don't know who asked for
  it (i don't have it written down here), so please forgive me for not
  crediting you with the idea. =)

    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!

Commit 512
* Add $levelwindow()
* Change default for /set new_server_lastlog_level to ALL,-DCC
  to prevent multiple servers having level dcc until i figure out why
  the code to handle this isn't working.  This value is more sensible anyways.

Add $outputinfo(), to help the scripter know what the output level/target is.
Garbage Collect some now unused code.

Commit 509:
* Move /DCC from commands.c to dcc.c
* Nix the "dcc deadlist" crap.  Handle deleted dcc's more sensibly now.

* Add "QWORDS" as new arglist type, for quoted-words with "s left in.
* Add "arglist" regression test.
* Fix strlcpy() in compat.c so it doesn't walk off end of string.
* Implement more sensible "locking" mechanism for dcc's
* Nix the nominally unimplemented "encrypt" feature for dcc
* Create "dcc_create" to create dcc entry
* Remove "creation" functionality from "dcc_searchlist"

* Add "get_dcc_by_filedesc" and "get_dcc_by_refnum" to look up dcc's
* Add "lock_dcc" and "unlock_dcc" to prevent dcc's from being GC'd.
* Double check that all output that occurs in dcc.c goes to LOG_DCC
* Use dcc_open in dcc_raw_listen() instead of doing the network stuff directly.
* Allow "booster ctcp" to be sent for dcc chat re-offerings.
* Reorganize register_dcc_offer() so it doesn't create dcc until all is well.
* Reorganize process_outgoing_file() into sub-functions.
* Don't call "dcc_dead" or "dcc_check" in main io() looper.
* Fix new_next_arg_count() to use real_move_to_abs_word() to emulate $1 usage

These are relatively minor changes except for the $prefix() fix.

* commandqueues as per UPDATES.
* $prefix() fix and regression test as per KNOWNBUGS.
* /exec and nick rolling as per KNOWN bugs.

* Don't call 'whobase' (userhost caching) if too many users on channel.

Add totaly-experiemental code for ipv6-based dcc.  In theory, this should
work if you do /dcc chat nick -6
But I haven't tested this and i haven't got any way *to* test it.  So if
someone tests this and it works, let me know.  Or if it doesn't work.

Fix various specious warnings from gcc, also, don't test for "sun_len"
in configure; use "sa_len" test for that.

* Add "loader" info to "load_level" data; It's $2 in $loadinfo().

normalize_filename() since it obviously can't normalize something that is not
an actual bona fide filename.

/set show_end_of_msgs ON and to be thrown when OFF.

Commit 437

* Fix /on invite so it takes 3 arguments, not 2.

Commit #430
Fix bug when you're connected to two servers in two windows, each with
channels, and you /server from one over to the other.  The bug was a
panic caused by me changing a -2 into NOSERV instead of into a -3.  Doh.

Commit #427

wasn't, which is bad.

Fix bug with doing SCROLL_FORWARD after SCROLL_HOME

Ach.  Here goes nothing.
Major commit which does many things, but the most prominent of which
is the final integration of the scrollback buffer with the hold buffer.
This fixes several annoying "features" and introduces a small truckload
of new features which have been requested recently.  Please see the
KNOWNBUGS or UPDATES file for more info, since I don't want this message
to be ridiculously long.

Fix /log not logging anything due to botched test.

Document the /LOG command.

Fix /alias /s to use %lu for unsigned longs in say().

Truncate these files.

New keybindings system coming through.  Details can be found in doc/keys
and in a few other places. :)
-wd

Document the rest of the changes...

Add request by larne.

Check for getaddrinfo() and getnameinfo() in configure
otherwise we can't do ipv6 lookups. doh!

Update documentation prior to epic4-1.1.6 release
Add "HAVE_GETSERVBYNAME" check to configure stuff.
Remove /SET RANDOM_LOCAL_PORTS which has gone away.
Fix some layout issues with gailib.c and change two function names.
Fix comment issue with ircsig.c
Fix uninitialized variable issue with keys.c
Remove mention of /SET RANDOM_LOCAL_PORTS in network.c

Add GAILIB, a bsd licensed getaddrinfo/getnameinfo implementation for
ipv4 only systems.  This was lifted from ruby, who lifted it from WIDE.
Add #ifdef's as necessary to compile on non-ipv6 systems.

Add a request i thought of.

Added /STACK ... BIND (per discussion w/ hop)
-wd

Moderate code layout cleanup in dcc.c
Don't arbitrarily restrict DCC handshakes to IPv4.  Getting closer to
supporting DCC-over-IPv6!

Fixed NULL deref if you do /FE without any arguments.

Add nominal support for generating IPV6 dcc handshakes in the handshake
generator.  Please note that we still don't have any way to actually create
an IPv6 DCC connection with which to generate a handshake, so this doesn't
mean as much as it might appear.

* Add Getnameinfo(), front end to getnameinfo() takes GNI_INTEGER for DCC use
* Fix inet_ntostr() to use Getnameinfo() instead of getnameinfo() directly.
* Fix inet_ntostr() to return int for success/failure, not hostname.
* Fix the DCC handshake generator to use inet_ntostr().
* Fix callers of inet_ntostr() to handle integer return values.

Document recent changes.

* Allow $listen() to take a family argument, like $connect().
* Add some V6 macros in ircaux.h, modeled after V4 macros.
* Add a "family" member to the dcc structure.  Default to AF_INET for now.
* Start fetching ports by calling inet_ntostr() instead of peeking directly
  -- into the sockaddr.  This yields protocol independance.
* Fix bug where $listen() or /dcc send w/o a virtual host caused NULL deref.

Remove the (now) obsolete decl of inet_aton() in ircaux.h. Reported by genok.

Oh, nothing important, just make $connect() support ipv6.

;-)

Lots more work on the ipv6 front.  Remove the last of the vestiges of the
old historical address handlers (inet_ntop/inet_pton/inet_aton/inet_ntoa).
Now everything, and I mean EVERYTHING goes through inet_strton and inet_ntostr
which are just fancy front ends to getaddrinfo() and getnameinfo().  Quite a
bit of EPIC is already family-independent, but there is still some left to be
clubbed into submission.  The project to add support for IPv6 is now about
75% complete!

Perversely enough, the only thing stopping DCC from being essentially 100%
IPv6 capable is the inability to send an IPv6 hostname through a handshake
without breaking the standard...

* Fix parse_server_info() to properly handle ipv6 p-addrs
* Add support for [<ipv6 p-addr>] to parse_server_info().
* Fix an off-by-one error in Getaddrinfo.  Bleh.
* Fix a malloc() size mistake in Getaddrinfo.

In connectory(), we were guessing what the address family was by "peeking"
into the hostname.  We did this so we could get the proper virtual host
family.  But getaddrinfo() can convert AF_UNSPEC into eg, AF_INET, so
instead of guessing at the family and getting the virtual host first,
get the remote host first, allowing getaddrinfo() to tell us what the
socket family is, and then use that to get our virtual host.

At this point, i believe that network.c actually supports ipv6 connections
by way of AF_UNSPEC (if you give it an ipv6 p-addr).  There's no support for
it in /dcc or /server yet though, but that's coming up!

Fix some function names that I didn't like after sleeping on them.
Add extra argument to inet_ntostr() which is passed to getaddrinfo().

OK.  So i had some inspiration and decided not to go to bed.  Vastly
simplify the conversions between sockaddr/host/p-addr to sockaddr/host/p-addr.
More simplifications yet to come.  IPv6 support is roughly about 50% done now.

Huge major commit #1 in the great IPv6 support addition...
Rather than include all of the changes here, read KNOWNBUGS changes.

Really fix wserv this time.  Really.

Add $killpid() for Liandrin.  I have no idea if this works or not.
Want to test this for me? ;-)

Update docs for EPIC4-1.1.4

Make $connect() protocol independant.  This requires changing dcc->offer
to a (struct sockaddr_storage) and requires changing dcc_open and even
register_dcc_offer.  Much progress being made on the protocol-independance
of DCC.  Somehow I doubt IPv6 will ever come to DCC, but it's nice to at
least say that we'll be prepared when it comes...

* Convert more (last?) inet_ntoa to inet_ntop, and inet_aton to inet_pton.
* Fix bug with $convert() (one_to_another)
* Try to make /window create only bind to 127.0.0.1.

Nuke "local_addr" in server struct in favor of "local_sockname"
Convert server to use "connectory"
Convert wserv to use "connectory"
Nuke connect_by_number()
Reorder functions in network.c

Fix those three annoying functions in network.c that use static local
variables, making them non-reentrant and fraught with peril.  Now they
require you pass in space to put the results.

This is a huge monster commit -- I put the particulars of the commit in
KNOWNBUGS.  I will only say here that this fixes a lot of issues with
DCC and introduces a lot of protocol independance into the networking API
that epic works with.  Good things will continue to come in the future!

Check (struct sockaddr) for sa_len, and use this as a hint as to whether
sockaddrs have a "length" field in them.  I will phase out the (now obsolete)
check for HAVE_SUN_LEN in configure, once i'm comfortable that checking for
HAVE_SA_LEN is sufficient.  Whack up the (struct sockaddr_storage) to honor
the HAVE_SA_LEN value probed by configure, as requested by Q (Kurt R.).

Regen configure.  This brings the ssl stuff into play from CE's last commit.

Fix bug with kb/s not showing up in /DCC LIST for /DCC GETs.

Fix two bugs regarding the output handler:
1) (Reported by |rain|) -- If an attribute change is found in the MIDDLE of
   a word, and that word is wrapped from one line to the next (ie, it is the
   word that is wrapped), then previously, epic was thinking that the
   attribute was already turned on at the end of the previous line and not
   in the next line.  Anyhow, every time we mark the "word break" position,
   save the current attribute set -- THAT is what we want to "bleed" into
   the start of the next line.
2) Speaking of "bleeding", output_with_count() wasn't doing a term_all_off()
   at the end of the physical line, which permitted attributes to "bleed"
   onto the next line's /set continued_line value, which is DEFINITELY the
   wrong thing to do.  Fix output_with_count() to turn off all attributes
   at the end of every line to prevent this "bleeding".

Reset the log for 1.1.4.

Remove a // comment in ssl.c -- C90 (which we target) doesn't have that.
Document the rest of the stuff that's changed in KNOWNBUGS.

This is my first go at supporting embedded colons in server specs.
You can use double-quoted words now in your server spec.  Man, I Hope
this doesn't break anything (famous last words).  Here's an example:
	/server /tmp/.ircd/6667::"tmp:pass":hop:groovy

Would add "/tmp/.ircd/6667" as a server, with the group "groovy" using
the nickname "hop" and the password "tmp:pass", all without the double
quotes, of course.  Using double-quotes to surround arguments like this
will protect colons inside from being mistaken.  I would like to support
backslashed colons at some point, but since backslshes are perfectly legal
nickname characters, I can't see a way to do this without hackery. :/

I added a "findchar" function in ircaux.c to find the next instance of
a character that isn't backslashed.

More documentation changes -- getting close!

Document yesterday's changes.

Bulk commit:
1) Fix typos in KNOWNBUGS
2) Flesh out the things in UPDATES that need documenting
3) Add target_file_write() to files.[ch] for send_text()'s use.
4) Create "reg.h", to hold protos for reg.c
5) Add some missing protos.
6) If /redirect'ing to 0 or to @<fd>, don't output to the screen.
7) Messages sent to target 0 are dropped (/redirect 0 now actually sends
   to target 0, and epic drops it.)  You can /query 0 now if you want.
8) Messages sent to @NUMBER get sent to the NUMBER file, where NUMBER is
   returned by $open().  For example, to paste stuff to log but not to screen:
        @fd = open(FILE w)
        query @$fd
        <paste some stuff>
        query
        @close($fd)
   or
        @fd = open(FILE w)
        redirect @$fd lastlog foo
        @close($fd)
9) Add a function to reg.c to compile a pattern into a regex -- experimental.
10) Fix some compile warnings regarding ssl.

I think KNOWNBUGS is up to date now.  Please double check before the
next release!

The whole ROM_CHAR thing was an accident waiting to happen.  Removed.
Add /SET ALLOW_C1_CHARS to protect from the ascii char 128-159 attacks
upon XTerm and GNU Screen users.  Defaults to OFF.

Thanks go to crazyeddy and zinx for working on this in my absence.
Add /set rom_char (defaults to off) which determines whether ^R rom_char
sequences will be honored or dishonored by epic.  Dishonored sequences
are not removed; they are just mangled.  This will help you detect those
who might try to use this feature for less than noble purposes.

Re-set the ^R character to "mode 5" processing; it had been set to "mode 6"
as a stop-gap measure.

Updates and credits.

"Doctor, it hurts when I do this!"
"Then don't do that!"

Yes, we should be doing the expansion at runtime
What we should not be doing is the expansion at registration time.
Revert the last change, and continue doing expansions at runtime.
"Fix" /queue so it does not call expand_alias() up front.

prepare_display() was appending an ALL_OFF to the end of the last line,
but that's not the right thing to do any more since ALL_OFFs have been
converted to Attributes before calling prepare_display().  Anyhow, append
a zero-valued Attribute at the end of the last line in place of the
ALL_OFF -- reported by fudd.

Document some of the changes that have happened recently.

* Fix $printlen() -- must call normalize_string() before output_with_count()!
* Make 'add_to_window' and 'window_disp' static to screen.c again.
* "Fix" /WINDOW ECHO to not call add_to_window() but rather use "to_window".
Commit #150

Fix bug that showed all timers as having 0 seconds remaining. Founds by ce.

Do not hook /on general_notice if the user hooks /on kill or /on oper_notice
to prevent multiple hookings of the same notice.

Start exposing the commit_id to the user in debugging messages and other
various places.  Since this will appear along side the version id in things
like panic messages, this will greatly help aid in tracking down specific
issues.

Fix register_dcc_offer so that when trying to determine if a file exists
or not, it honors the /set dcc_store_path setting.  This prevents otherwise
spurious warnings, and does help the user avoid clobbering a file.

~/.epicrc support!  kb should like this.

Honor attribute markups in /set continued_line
Save the attributes at the line-break point and reset them after we
have pressed the /set continued_line in the next line.  This means that
having color/bold/whatever in your continued_line won't "cancel out"
any color/bold/whatever you had going on in the text.  The continued_line
markups end at the end of the continued line text.

This is the new highlight/attribute renderer.  It is a "true renderer"
because it actually renders things to look like what you say.  No longer
does turning on some attributes (color) turn others off, nor does turning
some off (bold) turn others off.  Some things may break with this, please
let me know, or feel free to pitch in and fix them.

Zinx will be happy to know that i did NOT use the epic5 "prepare_display"
routine because he was right, i did totaly break it.  I used the epic4
prepare_display function but just made it aware of the new attribute stuff.

Implement the "redirect sink", which instead of sending all output to another
irc server, drops the output entirely.  This is used by /flush (which is now
safe to use again) and can be used by the user via /redirect 0 to execute
a server query but suppress it's output.

Extend /pause <seconds> to support fractional seconds, ie, /pause 1.5

The beginning of the migration away from 'time_t's towards 'struct timeval's.
This first round of support is very rough and may have some issues, which
I will be happy to fix (or you can fix them yourself if you want), but it is
more proof-of-concept work for now.  I don't expect that I will migrate
*everything* to struct timeval, just the important stuff.  I have not made
any serious attempt to optimize this yet and please don't jump the gun and
start optimizing this until I've got the bugs settled out.  Thanks. =)

Oh yes, I almost forgot the good part -- /timer now has highly accurate
sub-second timer resolution.  This means you can do /timer 0.82 echo test
and it will go off in exactly 0.82 seconds.  No more "approximate" timers!

The traditional restrictions about timer execution (timers do not go off
while another timer is executing, and while you are /wait'ing) still apply.

Update the docs, fix the sorting in the functions list (oops).

Let the work on 1.1.2 commence!

This is a bulk commit -- it includes $unsplit(), a new built in function,
as well as documentation updates.

This is the last of the work before epic4-1.1.1.  If any of you want to
make any more changes, please make them right away.  Please feel free to
test this over the weekend, because EPIC4-1.1.1 will be released as an
alpha release next monday.

I forgot to give proper credit for where i got the +M stuff from.
It came from adm.

Add /set auto_rejoin_connect -- this controls whether epic will try to
rejoin your channels when you are disconnected from a server *AND EPIC
WOULD ORDINARILY TRY TO REJOIN YOUR CHANNELS*.  This has *ABSOLUTELY NO
EFFECT AT ALL* in those cases where epic has thrown away your channels
and has no intentions of rejoining them.  This is only a way for you to
reduce current functionality, there are no bugs fixed with this.

Document the fix i just made.

Commit the latest and greatest KNOWNBUGS file.

Document changes in KNOWNBUGS.

* Add /window rebind, which moves a channel binding forcibly to a new window
* Add /window rejoin, which joins a channel in the window you want it to go.
* Make /join use /window rejoin, you can use it in an /on now! Huzzah!
* Fix move_channel_to_window to revoke /window bind when a chan moves away.
Commit 92

Add $halfop(), channel half-op status (+h) -- returns 1, 0, or -1.
Written by ay-ar.

* Fix server assignment in /exec so it works in /on's again.
* Fix failsafe declaration for MAXPATHLEN for hurd in irc_std.h and glob.c.
* Fixes to make dcc-over-ctcp-over-dcc work again (|Rain|)
* Fix $querywin() so it can take a second argument, a server ref (for scromp)

Permit double quotes in the target of /msg, Reformat some of the
stuff that ce commited, and fix an issue with word breaking.

Fixes for multiple timers with the same refnum and channels getting confused after being klined

The "Can't join channels" numerics were not having their /on's thrown
because i moved them from zone 3 to zone 1 but forgot to add the call
to do_hook for them.

* Move the "can't join channel" numerics into section #1, suppress them if you
  are actually on the channel already!  Add "cant_join_channel" function in
  names.c to wipe out window->waiting_channel(), and use it in the "cant join
  channel" numerics.

Fix a bug with /disconnect sending QUIT to the server rather than
	calling close_server(), which causes all sorts of mayhem.
	This was reported by Robohak, by way of felony (i believe)
Fix a bug with fudge_nickname() not calling nick_command_is_pending(0)
	when a 433 numeric (Nick is in use) happens, which causes any
	further 433 numerics to fail to fudge the nickname!  D'oh!
	This was reported by Q.

Use FD_CLR to prevent multiple hits on a file descriptor between select
calls.  Discovered by Q when he was testing the 010 redirect handler.

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

Commit #51 -- save channels when server drops our connection.
I guess this got overlooked.  Q is responsible for pestering me
into fixing this. ;-)

Commit #50 -- EPIC4-0.9.17!

EPIC4-0.9.16-11 -- support 477 numeric on dalnet.

Add the /for <var> in (<list>) {<commands>} command
Add the /for <var> from <min> to <max> {<commands>} command
Implement "break_args" that breaks argument lists to commands to an array.
Implement "skip_spaces" which skips leading spaces in a string.
This is commit #46, isn't it?

Commit #42 -- Add $ssl() function, which always returns 0.
This is for lateral compatability with EPIC-ssl.

Commit #35 -- Update the KNOWNBUGS file since 0.9.15
Update the UDPATES file since last september (sheesh)

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!

Roll get_connected() into reconnect() and abolish all uses of get_connected().
Things are starting to look good here!

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!

Fix up the rest of the change log.
This is an amendment of commit #16.

Commit #16 --
* Update the FTP mirror list
* Clean house on the KNOWNBUGS list
* Make 'remove_window_from_screen' a static function
* Fix bug where /on switch_windows * {window $3 double}
  combined with /window hide in a window with channels induced a panic.
* This is commit #16.
