This should get rid of some annoying untracable (and usually rare) crashbugs in the
old resolver. Besides that, it makes things look more clean and understandable.
This should be the fix for the following bugids (all the same issue): #2499, #2551, #2558,
#2559, #2603, #2642, #2502, #2501, #2618, #2616.
Feedback and testing is very much welcomed (syzop@unrealircd.com).
It also sends a numeric to the user saying the command has been processed, but a copy
has been sent to ircops. I feel this is a good idea for privacy reasons (anti-spy),
though I don't know how users will react to this. If you are using this on your network
and get users bothering you about it (or before that ;p), it's probably a good idea
to explain it somewhere on your site or FAQ :).
Example usage:
/spamfilter add p warn - Testing_mirc_decode_filter \$decode\(.*\)
[WARNING] The numeric text is likely to change in the next few weeks (early-cvs-commit).
- If a class block was removed and any other blocks would be referencing the class block
(such as: allow::class, oper::class, link::class), then this would cause a crash.

and 2000 lines total that can be hotfixed if needed ;). The effort involved in moving all
this sucks a lot though :/. This might need some more testing to make sure it doesn't break
anything.
- Updated support OS list in documentation.
- Build in some additional checks (especially for Chinese).
- Fixed a bug in chinese character range (affecting 3.2*)
- Relaxed nick character checking from remote servers (rely on NICKCHARS= PROTOCTL
to deal with problems). This is useful to prevent any kills in case we slightly
change the characters that are allowed in a language.
If 2 servers try to link and the allowed nick characters do not fully match, then
the link will be rejected. Note that this will not prevent you from 3.2.2<->3.2.3/CVS
charsets mistakes, but only with linking CVS/3.2.3+ servers. Suggested by Troco (#0002360)
This might need some additional testing, but initial results are positive :).
still cutoff if the nick is too long. Basically this is the same way as Hybrid does it
so it should work ok :).
- Added nick character system. This allows you to choose which (additional) characters
to allow in nicks via set::allowed-nickchars. See unreal32docs.html -> section 3.16
for a list of available languages and more info on how to use it.
Current list: dutch, french, german, italian, spanish, euro-west, chinese-trad,
chinese-simp, chinese-ja, chinese.

throttle the number of joins per-user to X in Y seconds. Idea from Angrywolf (who
wrote a module that did this before). This might need some more testing :).
It's enabled by default but can be #undef'ed in include/config.h (line 449).
(perhaps this should be a different function?). Anyway, this means less diskspace
is needed (~1.5mb or more), and it also makes it a bit easier for RBAC (#2300).
- Made a new function DoMD5() which is ssl/non-ssl independent. Also made the cloaking
module and the auth functions use it. Hopefully I didn't break anything ;). Suggested
by Bugz (#2298).
- Modulized a lot of commands and related subfunctions: NICK (750 lines), USER (200),
MODE (2300), WATCH (250), JOIN (600), PART (250), MOTD (100), OPERMOTD (100),
BOTMOTD (100), LUSERS (100). More will follow soon (probably including more subfunctions
related to existing commands).
- [Module coders] Added new function: do_cmd(cptr, sptr, cmd, parc, parv) which is an
uniform method to call any other commands. For more info, see description in src/parcket.c.
This will be used for any further modulization of commands that need to call other
commands, like NICK (will be done soon).
to send to normal users w/the snomask set.
- Fixed dcc filtering a bit more.
- Made usermode 'g' operonly since it didn't do much, reported by DukePyrolator (#0002024).
work just the same as the HOOKTYPE_LOCAL_* variants).
- Module coders: HOOKTYPE_REMOTE_CONNECT is now also called during net-merge. You can use
IsSynched(sptr->srvptr) to find out if it's called due to a net merge (0) or a connect (1).
- Added spamfiler 'user' (u) target. This regex is checked against nick!user@host:realname
when a user connects. This makes it easy to ban drones with simple patterns.
For example: '/spamfilter add u gzline 86400 Drone[0-9]+!.+@.+:Drone[0-9]'
would kill any drones that have both a nick and realname with 'Drone' followed by digits.
/connect or autoconnect) and was not present in the cache. Reported and traced by sh0
(#0001976).
- Fixed compile bug at *NIX caused by ModuleGetErrorStr fix.
multiple reference count bugs, one related to sptr->serv->conf, and another one related
to sptr->serv->class. Both caused problems when someone did a /rehash when a server
was in the process of connecting (so it might also happen when connfreq was hit and you
did a /rehash). Original bug was reported by sh0 (#0001872).
- Module coders: if CmdoverrideAdd() is called for an override that is already in place, it
now sets MODERR_EXISTS as errorcode and returns NULL (previously it added duplicates).
In the past module coders had many issues with PERM mods... you had to use weird tricks,
but now you can (and should!) just override on INIT and on HOOKTYPE_REHASH_COMPLETE.
- Moved register_user declaration to h.h, updated call in m_pingpong.c (due new 'ip' field).
- Usermode +v ('receive dcc send rejection notices') is oper-only now for privacy reasons.
- Added dcc allow { }, which allows one to make exceptions over deny dcc { }.
- Added deny dcc::soft and allow dcc::soft item, if set to 'yes' it allows someone
to explicitly override it per-person via /DCCALLOW (see next).
- Added DCCALLOW system, taken directly from bahamut.
With this system you can block certain (or all) DCC SENDs and then allow the user to
'override' this limit for every user he/she trusts via '/DCCALLOW +User'.
This is an attempt to stop (or at least limit) the spreading of viruses/etc.
See '/DCCALLOW HELP' for more info.
- Added example dccallow.conf which filters everything except some known
'safe types' (jpg, jpeg, png, gif, etc). Note that the purpose of this file
is NOT to get a complete list, rather to limit it to a few 'known safe' entries.
- Added set::maxdccallow: max number of entries of the DCCALLOW list (default: 10).
- Fixed a few wrong macro's (ircstrdup/ircfree) in s_conf.c causing
very weird behavior... This also fixes a bug where set::spamfilter::ban-reason
would have the value of ban-time.
- Improved spamfilter again.
- The new syntax is:
/spamfilter [what] [type] [action] [tkltime] [reason] [regex]
[tkltime] specifies the duration of any *lines placed by this rule.
[reason] specifies the *line, kill and/or block reason.. no spaces
allowed, but '_' will be escaped to a space.
In both cases you can simply use '-' to skip and use the default.
Ex: /spamfilter add p block - - Come watch me on my webcam
/spamfilter add p gline 3h Please_go_to_www.viruscan.xx/
nicepage/virus=blah Come watch me on my webcam
- A message is now shown if the msg/notice/dcc is blocked.
- There are 2 new spamfilter action types:
'dccblock' will mark the user so (s)he's unable to send any files by DCC.
'viruschan' will part the user from all channels and join
set::spamfilter::virus-help-channel (default: #help).
this action might be improved to do more later.
- Internal: added EXTTKL PROTOCTL, this determinates if 10 parameters
instead of 8 are supported for m_tkl (used by spamfilter add).
This new system needs some testing... :)
- Added snomasks 'S' (Spamfilter) which notifies you of any spamfilter matches.
- [internal] always return after spamfilter match, don't continue looping trough
targets list (eg in case of: /msg #a,#b,#c spamspam), otherwise you would get
duplicate notification msgs.
- Added SENDSNO server command, similar to SENDUMODE but for snomasks, this is
used by the spamfilter snomask (+S) so you get network-wide notifications.
- Added "compiled for.." versioning system, this way a beta17 module can't be loaded
on beta18, etc... People often forgot to recompile their modules or had old ones
somewhere by mistake, therefore crashing after upgrades... this should fix this
(in the future). Module coders don't have to do anything for making this work,
it's done automatically (via modules.h).
spamfilter::word to spamfilter::regex to make it even more clear (since we match
on the whole line and have nothing to do with words.. 'word' doesn't make sense).
- Updated docs with some better regex examples, reported by AngryWolf (#0001520).
