CVS log for epic4/acconfig.h

Request diff between arbitrary revisions

* Right about now Kev is wondering what is going on, that I'm making
  all these changes to epic4 after so many years of just bug fixes.
* Resolve build conflicts between x/open curses and ncurses. ugh.

* Add a missing cast for printf when sending a dcc handshake.
* Support isfinite() for hpux/c99 alongside finite() for bsd.
* Fix bug where SIGCHLD can be blocked and never unblocked.

More complicated atoll() replacements.

Wrapper for atoll() for freebsd-stable and stuff.

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.

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

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

Add support for clock_gettime() which is the posix version of gettimeofday().

Another merge.

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

Fix compile errors in configure.in.  These were my fault.

* Add checks/workaround for linux's broken realpath(). Bleh.
* Add arc4random stuff to compat.c -- will be used later!
* Fix $realpath() to use normalize_filename() so it gets realpath() fix.
* Add $serverctl(SET <refnum> PRIMARY) to set primary server.  User beware!

* #include <unistd.h> for configure check for sys_siglist[] for netbsd.

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.

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

Fixes inspired by first wave of testers
1) Fix casts to inet_anytop()
2) Fix configure to check for socklen_t, default to 'int'.

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.

Drums...
Drums...
Drums...
Drums in the deep...

Have 'configure' check for the worthiness of SNDLOWAT setsockopt option
so that the linux users stop griping to me that they don't like to see the
error message that linux's braindamage causes.

Rebuilt the configure script after applying SSL patch.

Applied the SSL patch from ay-ar.

Details are in README.SSL.  This works well at this point, but there may
be teething problems.

Add compat functions for setenv() and unsetenv().  Unfortunately,
if your system lacks these functions, setting environment variables
causes a memory leak, and you just plain flat out can't unset environment
variables.  These are defects in the API (or in the OS, whichever one you
prefer to blame) and do not represent bugs in EPIC.

More complete support for random local ports; /set random_local_ports now
cooperates with /setenv EPIC_USE_HIGHPORTS=1, and it works on freebsd,
openbsd, and linux, such as it is.

Re-run through autoconf to pick up -g -O instead of -g -O2.

Two patches applied, aka, the string and perl patches.

The perl patch adds perl support via three perl functions.

The string patch:
  * Rewrites new_realloc to more closely resemble new_realloc in its
    interface, and in that it calls realloc directly.
  * Adds an argument to the 3cat functions that permits it to seek
    directly to the end of the string.  Designed to improve performance.
  * Alters a few things to use the above.
  * Tunes a few other string functions in ircaux.c.
  * Rewrites $uniq() for performance reasons.
  * Removes the part of $jot() that preallocates the string.  I feel a
    little guilty about this somehow though it seems to have absolutely
    no effect on performance anymore.
