# Insert new changes at beginning of the change list.
#
--------------------------- Released 2.10.10.pl11.(release)
* Fixed G-lined (reason), thanks to dfx -- Isomer
* Added reason to the "G-lined (reason)" quit messages. -- Isomer
* Removed 'for nick[1.2.3.4]' from quit messages, they're redundant
  and make hub hiding more reliable --Isomer
* ircd/s_user.c (hunt_server): add 'No such server' message back 
  --Isomer
* ircd/s_bsd.c: remove ALWAYSFLUSH - the problem wasn't ircu's fault 
  -- Isomer
* ircd/m_names.c (m_names): don't add a space if the user's a
  zombie; fixes an overrun where we generate a huge number of spaces
  in the names reply without length-checking them properly -- Kev
* added 'ALWAYSFLUSH', if you thought the furgeson flusher was bad...
  --Isomer
* Fixed /USERHOST again.  Horribly embarrased.  Thanks again Liandrin 
  --Isomer
* Added extra field to /stats Y showing how many people are in that class.
  Information was previously available via /trace, however tended to flood
  you off if you weren't on a good connection.  Requested by Mr_RIP
  -- Isomer
* Fixed 'BADCHAN' resetting itself to 'Y', reported by Gator --Isomer
--------------------------- Released 2.10.10.pl10
* Released 2.10.10.pl10
* Backported /names optimisation from 2.10.11.
  '/names 0' now returns verbose listing, '/names' simply returns
  ENDOFNAMES. Disallow harmfull /names usage. --Gte
* Fixed ERR_NOSUCHNICK bug in userhost, thanks to Liandrin --Isomer
* Conceal more bugs in IPcheck --Isomer
* Add 'POST' as a unregistered command to disconnect people abusing web
  proxies --Isomer.
* Conceal bugs in IPcheck --Isomer
* Fix for changing the wrong define --Isomer
* Fix for the easter buggy. --Isomer
* Fix for rpong --Run
* Fix for other IPcheck bug, thanks BLMet. --Bleep
* Fix for IPcheck bug, rewrite IPcheck from scratch (mostly),
  add changes for new code to s_user.c, ircd.c --Bleep
* Shorten connection timeout for auth queries to 60 seconds
  If connection is from localhost use the server alias for the
  client host. --Bleep
* Fix for ident bug --Isomer
* Fix for rping/rpong --Gte
* Add m_pong to parser handler --Bleep
* Fix for EXTENDED_NUMERICS bug doh!!! --Bleep
* Fix for Max Undernet Server bug --Bleep
* Fix for PRIVMSG<->NOTICE translation from hubs --Bleep
* Fix for Bogus protocol strings for P9 servers --Bleep
* Hookup UPING code again, cleanups --Bleep
* Convert numerics back to mask and shift extended numerics
  follow same mechanism --Bleep
* Fixed bogus errno return on Solaris --Bleep
* Fixed core on RPING bug, tokenized RPING --Bleep
* Remove add_local_domain entirely, unused --Bleep
* Merge u2_10_10_beta06 create branch u2_10_10_beta07 --Bleep
* Remove size_t from socket calls, audit usage of size_t
  values. --Bleep
* Fix for OSF1, RES_NOALIASES not defined there. --Bleep
* Don't bother doing hostname lookup or setting me.sockhost
  since we never want to display it there is really no reason
  to have the info. --Bleep
* Bugfix broken N:line check in chkconf --Maniac
* Bugfix, fix clients occasionally getting stuck in IPcheck
  code. Add note to members in client struct that aren't used
  for any remote client code, didn't want to actually move them
  this close to release (paranoia) --Bleep
* A few little cleanups in check_pings, removed yet another
  address display. --Bleep
* Bugfix, autoconnects displaying server IP address to opers.
  --Bleep
* Remove names from /stats p, since its always the server
  name from the M:line anyhow, (redundant information)
  --Bleep
* Unborked throttling. --Bleep
* Fix two stupid bugs, related to IP mismatch kills. --Bleep
* Clean up configuration, make it a bit easier for admins to
  turn off asserts and heap checking code. Moved host name dns
  query for listener virtual host ports to dead code and use
  me.name for the listener name (no sense in looking up the name
  if we don't want to display it). Change direct bump of unknowns
  in s_bsd.c to Count_newunknowns(UserStats) for consistency.
  --Bleep
* Added option to kill any connecting client with a forward and
  reverse DNS mismatch. Fixed bug in s_auth that that caused
  incorrect counts for unknown clients. Replaced missing server
  notice for SNO_IPMISMATCH. --Bleep
* Added a few more little name tweaks, no sense in looking up
  the hostname in the conf if no one knows it. --Bleep
* Moved to beta archive, bumped patchlevel, fixed message for
  lost C:line in s_conf.c (I don't think I've ever seen this happen)
  --Bleep
* Finished host hiding changes, it should not be possible for any
  online user to discover the real hostname or IP address of any
  connected or unconnected server listed in the configuration. This
  applies to opers and regular users. The name in the M:line is the
  name used for connecting and all informational messages. --Bleep
* Removed code in dbuf.c that flushes the dbufs if the server runs out
  it looks like a fully loaded server may not be able to handle a net
  break without shedding a few clients. --Bleep
* Finish IP address cleanup, alpha should be clean for not displaying
  server hosts or IP addresses to users now. This needs to be verified.
  Changed version to u2.10.10 per Isomers suggestion. --Bleep
* Remove server IP address from info line for connecting servers.  
  This almost completes the IP address hiding changes for alpha, there
  are still a few stats commands available to users that will show the
  server addresses, but they can be easily disabled or only show '*'s
  to non-opers.  --Bleep
* Fix possible (but not likely) memory leak in debug allocator, couldn't
  find the "meg a minute" problem, using the debug allocator on the
  production network with more than 1000 clients on a server may cause
  problems if you don't have a lot of memory. (This does not seem to
  be a problem with non-debug builds) --Bleep
* Captialisation fixes, just to keep certain ppl quiet. --Isomer
* Removed +s channels from /list.  They were shown sometimes, but not
  others, and the information that was shown about them was inconsistant.
  list is not an effective way to gain information anyway. Reformatted
  and touched up readme.who as well.  --Isomer
* Added MAP to ISUPPORT, added doc/features.txt --Isomer
* Added suggestions made by scripters. more info for ISUPPORT, and
  added stuff to 'TODO' --Isomer
* More TODO items 'done'.  P:'s now ignore '*'s.  ping shouldn't do funky
  stuff with mirc anymore, needs discussion --Isomer
* Typo fixed. Now I'm annoyed.  --Isomer
* Right, Makefile's gonna work now or I'm going to get REALLY annoyed at it.
  --Isomer
* TODO, m_ping, ircd/Makefile.in: Added note to TODO, added info to
  m_ping, and fixed Makefile bug using bsdmake. --Isomer
* s_bsd.c, listener.c, s_user.c, s_serv.c, s_bsd.h:
  Set receive and send buffers in correct order to enable flow
  control for clients and support fat pipes better for servers.
  Finally got it right :)
  See Stevens "Unix Network Programming" v1 p 191-193
  --Bleep

  is sane. --Bleep

  if a dbuf allocation fails, attempt to flush all send buffers except
  for the one we are trying to build (we're twiddling with the list etc..)

  256th clone, Add more ipcheck forgiveness to s_user.c (needs work).
  Changed IPcheck_local_connect and IPcheck_connect_fail interfaces to
  use struct in_addrs instead of client structs to allow delaying the

  Added can_send function to send.c (should be called before work is done

* channel.c: Added Isomers netride2.patch, still needs a config option
  to turn it on (NO_INVITE_NETRIDE) --Bleep
* parse.c, msg.h: Added silent ignores for notices so connect progress
  messages do not cause connecting server to spew ERR_REGISTER_FIRST

* s_user.c (m_nick): IP differ patch, use IP address instead of host
  name to determine different user@host for nick collides. --Isomer

  to be left in client hash table after a name change. Discovered by
  Quant and Isomer. --Bleep
* hash.c (hSeekClient): fixed bug I introduced when reversing my hash
  table code changes, thanks Quant and Isomer --Bleep
* opercmds.c (m_lusers): send limited luser info to remote
  clients --Isomer
* numeric.h, channel.c, s_err.c: Changed invite list numerics

* config-sh.in, gline.h, numeric.h, gline.c, opercmds.c, s_debug.c, s_err.c:
  Add badchan patch by WildThang --Bleep
* config-sh.in, channel.h, numeric.h, channel.c, s_debug.c, s_err.c:
  Add lchanmode patch by David M --Bleep
* channel.c (cancel_mode): removed incorrect assert --Bleep
* *.c: removed P9 support, not everything is completely gone but most
  of it is, the server builds and connects to other servers, but thats
  as far as it's been tested so far. --Bleep
* ircd.h, ircd.c, s_bsd.c:
  removed BOOT_INETD/BOOT_CONSOLE code, unused non-functional --Bleep
* struct.h, ircd.h, ircd.c, s_user.c, s_bsd.c:
  removed BOOT_OPER/STAT_MASTER code, original patch by Isomer --Bleep
* s_user.c (m_nick): removed redundant check for acptr
* hash.c (hSeekClient, hSeekChannel): roll back some of hash.c changes
* hash.c (hSeekClient, hSeekChannel): removed unused variable from previous
   changes.
* hash.c (hSeekClient, hSeekChannel): fix compile error from status changes,
   fix logic bug that caused the first client that matched the mask to be
   returned regardless of whether or not it's name matched, this can result
   in wierd problems where the wrong server/client could be returned from the
   hash table lookup. Removed code that moved client to head of hash table
   chain for it's bucket when it's looked up, if the hash table is working
   reasonably well this just wastes cpu.
* hash.c, list.c: added code to zero out cptr->hnext when client removed
   from hash table, added assert for hnext == 0 in list.c to make sure that
   client was actually removed from the hash table before freeing it's memory.
* various: misc cleanups
* support.c: removed dead code
* configure.in: remove unneeded checks for minix, aix, ansi/posix headers
   these things are handled by porting layer code.
* res.c: remove calls to add_local_domain, these were causing incorrect
   behavior
* opercmds.c: cleanups in gline code
* s_bsd.c: increase socket buffers to 65535 for server connections
* crypt/mkpasswd.c: mutter correct runes to get file to compile without warnings
* gline.c, gline.h: add new files to attempt to encapsulate glines a bit,
   some code from opercmds.c needs to be moved here still
* opercmds.c (m_gline): fix local gline bug
* s_conf.c (initconf): add password change on rehash fix
* s_conf.c (rehash): fix rehash freeing and reloading the motd/rmotd files for
   every client connected.
* ircd_log.c: use 2K fixed buffer instead of vsnprintf, nothing we write to
   the log should ever exceed 512 bytes, but it doesn't hurt to be paranoid.
* res.c: change resolver timeouts to 5 seconds, per RFC1123
* channel.c: more little cleanups, no code changes
* channel.c: a) stops iterating over /invite list
    b) adds /invite to list the channels you're currently invited to.
    c) adds lotsa new numerics --Isomer
* ircd_signal.c, ircd.c: fix bug in signals
* channel.c (can_send) add Isomer's changes
* channel.c: add send_ban_list, cleanup a few names, reformat some parts to make
    more readable, fix bug introduced by name changes
* ircd_chattr.[ch]: add new macro for checking K:line time chars vs comments
* listener.c (show_ports): add code to show client/server and hidden status
* s_conf.c: bug fixes, cleanups, add code to set server port and hidden
    status for listeners (P:lines)
* s_conf.c (initconf): add interface selection code to P:lines so ports can
    be set on a single interface or multiple interfaces (multi-homed hosts)
* s_conf.c: rewrote C/N line code, removed N:lines entirely, clean up server
    conf line code.
* s_conf.c (check_server): move ip checks out of resolved or not so they can
    be checked for worse case situations on server connects
* res.c (resolver_read): add Isomer's debug info for failed resolver queries
* opercmds.c (m_stats): remove call to time(0) for each local client in 
    stats l command, use CurrentTime instead
* s_conf.c (initconf): only do lookups on C:lines instead of both C/N lines
* res.c: fix resolver hang bugs
* s_conf.c (rehash): remove extra semicolin that was causing c/n lines to
    accumulate
* s_conf.c (rehash): add portnum back to the listener list so we don't loose
    the server port on a rehash
* s_auth.c, listener.c: remove warnings for normal errors
* s_auth.c, listener.c: use osdep non-blocking calls instead of locals
* s_auth.c, listener.c: add code for non-blocking recovery for listeners and
    auth queries
* s_auth.c (auth_error): call IPcheck_connect_fail if the client socket dies
    during the auth check so the reference count doesn't get borked in the
    IPcheck code.
* numnicks.c: yet another extended numerics bug fix... sheesh
* s_bsd.c, s_conf.c: move conf line code from s_bsd.c to s_conf.c, cleanup
    cleanup check_server, check_client (still not completely tested, may be
    a bit buggy yet).
* parse.h, parse.c, s_debug.c: remove privmsg logging code
* numnicks.c (FindXNServer): fix off by one bug
* common.h, common.c: removed unused files
* s_bsd.c (net_connect_completed): new function, called after connection
    establishment for servers and clients, release reference count for
    the dns reply and set the socket buffer size to IRCD_READBUF_SIZE 
    for servers and 2K for clients.
* channel.c, crule.c: cleanup bogus casts
* listener.h (add_listener): fix bug that caused server a server port listener
    to think it was a client port listener.
* s_user.c, s_serv.c: release reference to dns_reply when connection is
    established.
* s_bsd.c (completed_connection): removed call to start_auth for connects
    the auth module expects connections not to be linked anywhere and owns
    the client struct until it's done.
* listener.c (release_listener): fix inverted assert client exit bug
* ircd_chattr.c: fix signed/unsigned warnings with Sun Workshop (+w)
* ircd_chattr.c, ircd_chattr.h: new files for character attributes and case
    translation, hopefully they will be a bit easier to maintain.
* s_conf.c (rehash): fixed logic bug that caused and infinite loop, 
    fix port update bug (needed to call mark_listeners_closing before initconf)
* *.c, runmalloc.[ch]: change the way the server deals with out of memory
    conditions. On server startup a no-memory handler is installed which
    calls server_restart if an allocation fails. Allocations are now checked
    in the memory allocation functions. Added asserts after every allocation
    to verify for debug.
* *.c *.h: move authentication and dns to authentication module rename a few
    globals, const correctness fixes, add ircd_string code, rework network
    code, use dns callbacks, removed a lot of redundant code 
* s_bsd.c: finish this stage of net code work
* *.c, *.h: rewrite select and poll code, add listener.[ch] net.code overhaul
    in progress, prepare for adding auth module
* s_bsd.h, struct.h: moved client struct macros back into struct.h for now,
    the last place they belonged was in the network code... feh
* ircd.c (open_debugfile): removed client for debug file
* ircd_string.h, ircd_string.c: new files for string processing, add
    ircd_strncpy function
* *.c, *.h: rename ircstp to ServerStats
* *.c, *.h: rename now to CurrentTime
* listener.h, listener.c: new files for listener ports
* include/ircd_defs.h: new file for global definitions (HOSTLEN, USERLEN)
* struct.h: add local_flag to client struct, to make local/remote detection simpler
* s_bsd.c (read_message): split out separate versions for select and poll
* s_bsd.h, various source files: remove the rest of the unix domain socket 
    support this removes a number of comparisons that were unneeded in 
    code that should run reasonably fast.
* os_*.c, res.c, ircd_osdep.h: add os_recvfrom_nonb for resolver
* os_*.c, s_bsd.c, s_auth.c, ircd_osdep.h: add os_get_sockname, os_get_peername
* bsd.h, bsd.c: merge into s_bsd
* ircd_osdep.h, os_generic.c, os_linux.c, ircd_osdep.h: move os variable stuff
    to separate compilation units, os generic contains the original code
    (start here). 
* s_bsd.c, send.c, struct.h: remove pyr (pyramid) finally
* res.h, res.c, s_misc.c: cleanup headers/dependencies in res.h
* match.h: include sys/types.h before netinet/in.h, broken BSD system headers
* ircd/Makefile.in: remove CFLAGS from link line, use LDFLAGS instead
* ircd.c: add missing include for sys/socket.h
* common.h (strChattr, strCasediff): remove pointless non-portable inline
    decls. The functions are complex enough that inlining just bloats the code
* ircd_xopen.h, ircd_xopen.c, s_user.c, s_serv.c: porting layer for crypt and
    other xopen library calls, moved crypt to ircd_xopen.
* s_uping.c, s_uping.h, s_bsd.c, s_misc.c, s_bsd.h, ircd.c, s_debug.c:
    Removed s_ping. There are much better tools available that actually work
    correctly. The s_ping code was a waste of resources, and has historically
    given incorrect results (it never worked correctly).
* ircd/s_bsd.c, res.c, s_user.c, s_serv.c: little fixups to allow code to
    build on Solaris, still have some warnings there.
    TODO: wrap crypt and things that depend on _XOPEN_SOURCE in their own
    file so it doesn't bother the network code.
* ircd/s_bsd.c: cast option arg to const char* for setsockopt (solaris)
* ircd/Makefile.in: removed hard coded dependencies for hash.o chkconfig.o,
    let the automatic stuff take care of it, it does it better than humans.
* *.c *.h: remove register keywords, attribute macro junk, cleanup
    dependencies, rename MIN and MAX to IRCD_MIN IRCD_MAX all headers in
    C files are sorted, removed as many duplicate includes as I could find
    (dozens) general cleanups. Mutter the correct runes to get the protoype
    for crypt included where it was needed.
* *.c *.h: dependency cleanups up to querycmds.c
* ircd.c, bsd.c, s_bsd.c: move signal handling code to ircd_signal.c
* ircd_signal.c, ircd_signal.h: new files, use only POSIX signals remove
    support for unreliable signals.
* *.h *.c: include guards, dependency cleanups
* Configure.in, setup-sh.in: include guards, config.h includes setup.h
    add config dir to include path
* sys.h: include guards, remove hard coded path to config.h
* s_user.c (hunt_server): fix logic bug
* numnicks.c (SetServerYXX): fix off by one error
* multiple files (n2k patch): add code to handle extended numerics
