each time it executes, how LONG it takes to execute. When a certain
threshold
is reached the IRCd will warn or even remove the spamfilter. This will
prevent
a spamfilter (regex) from slowing down the IRCd too much, though it's
still not
a guarantee that it will never go to a halt (eg: in case it takes several
minutes to execute a regex or loops forever).
Warning can be configured via set::spamfilter::slowdetect-warn (default:
250 milliseconds) and automatic deletion of spamfilters if it takes too
long is set through set::spamfilter::slowdetect-fatal (default: 500 ms).
NOTE: slow spamfilter detection is currently not available on Windows.
NOTE 2: to disable slow detection you can set the warn and fatal settings
to 0 (zero). OR to really disable all code, remove SPAMFILTER_DETECTSLOW
from include/config.h and recompile.
This new feature (away notify) is announced in 005 (ISUPPORT) as: WATCHOPTS=A
Format is: WATCH A +UserOne +UserTwo
New numerics to cope with away notification in WATCH are:
RPL_NOWISAWAY: to indicate the user is away _when adding_ it to WATCH list
RPL_GONEAWAY: user was not away, but is now
RPL_NOTAWAY: user was away, but is no longer away
RPL_NOWISAWAY: user was away, and still is, but the reason changed
Example:
WATCH A +Target
Request to add user 'Target' to the watch list with away notification
:maintest.test.net 609 MySelf Target ~blih test.testnet 1204309588 :not here atm
Reply to watch add: user is online and away, reason is provided
:maintest.test.net 599 MySelf Target ~blih test.testnet 1204309588 :is no longer away
User is back (no longer away)
:maintest.test.net 598 MySelf Target ~blih test.testnet 1204309722 :lunch
State change: user is now away, reason is provided
:maintest.test.net 597 MySelf Target ~blih test.testnet 1204309738 :shopping, bbl
User is still away, but reason changed.
The syntax for each numeric is:
<nickname> <username> <hostname> <awaysince> :<away reason>
In case of 599 (RPL_NOTAWAY) it is:
<nickname> <username> <hostname> <awaysince> :is no longer away
For the record, this is all based on a draft from codemastr from 2004, which was
implemented in Unreal3.3 (devel branch) in 2006. Today, in 2008 it was updated
with away reason support and backported to Unreal3.2. Because away notification
hasn't been used until now (due to it only being in Unreal3.3) we felt it was
safe to break some numerics.
properly (..again..), this was previously reported by pv2b.
- CGI:IRC + IPv6: Fixed issue where all cgiirc ipv4 clients were rejected with
the message 'Invalid IP address', reported by stskeeps (#0003311), nate
(#0003533) and others.
will be backwards compatible as well, SJOIN doesn't care (TM) and mode
doesn't either in case of a server sending it. So this will be just a
client protocol modification.
when trying to /connect to a server with wildcards (* and ?) in the link
block. We also raise an error if link::options::autoconnect is used
together with wildcards in hostname.
new commands SVSNOLAG/SVS2NOLAG (syntax: SVSNOLAG [+|-] NickName). Obviously, care
should be taken when giving such access to a user since he/she will be able to flood
at full speed and could possibly take down the entire IRCd (well, everyone on it).
Suggested by avb, coded by djGrrr.
error, reported by Bock (#0003114).
- Added information about extbans to help.conf (/HELPOP ?EXTBANS). Patch from Bock
(#0003113).
- Made SAPART work for mulitple channels, just like SAJOIN. Patch provided by Bock
(#0003064). This also fixes SAPART now being announced to all opers globally, just
like SAJOIN.
- Finally fixed /RESTART issue on windows for good, should now always restart correctly.
Patch provided by BuHHunyx and Bock (#0002734).
- Fixed set::dns::bind-ip directive seen as duplicate, reported by aegis (#0003074).
- set::dns::* block is now no longer mandatory. All info has always been read from
/etc/resolv.conf (*NIX) or the registry (Win32), and the set::dns block is ignored
(except for set::dns::bind-ip, but that's a special case). Suggested by many including
djGrrr to make things slightly more logical (#0003019).
- As a consequence of the above, set::dns blocks were removed from doc/example*conf.
- Added two more characters to Catalan charset, reported by rmh (#0002995).
- Added set::pingpong-warning [yes|no] which decides whether to send the "** If you are
having problems connecting due to ping timeouts, please type /quote pong .." message
to each client when NOSPOOF is enabled (usually on Win32). The default is NO.
Previously this message was always sent if NOSPOOF was on, which often caused
confusion among users. The message was intended for non-confirming clients, but these
should be fixed by now, and those that were not fixed (self-made bots/etc) did often
not understand the message anyway. Anyway, you can still turn it on ;). (#2680).
user target string (nick!user@host:info), insteaf of doing it at like 5 places.
- Spamfilter target 'u' (user): the host field (nick!user@HOST:realname) is now escaped
with brackets if it's an IPv6 address, eg: blah!blah@[1:2:3:4:5:6:7:8]:hello, reported
by aquanight and others (#0003010).
instead of letting it magically reappear whenever +x is set. This means services can
now properly "unvhost" a user by sending a "SVSMODE User -x+x" (then any existing vhost
will be removed and user will have a cloaked host). Reported by avenger and others
(#0002933).
