Add a new signal, server destroyed, that is supposed to run the clean up
tasks of server disconnected. This is so that some structures will stay
around longer.
This patch changes the internal name of SSL to TLS. We also add -tls_*
options to /CONNECT and /SERVER, but make sure that the -ssl_* versions
of the commands continue to work like before.
The IRCv3 SASL extension says that AUTHENTICATION payloads of exactly
400 bytes in length indicate that the message is fragmented and will
continue in a subsequent message. Handle the reassembly and splitting of
these messages so that we are compliant with the specification.
This fixes two issues:
- IRCNet doesn't have STATUSMSG, but it supports +channels, and
including + in the default value meant processing those incorrectly
- The "bahamut hack", for old servers that support but don't advertise
STATUSMSG, didn't work since ischannel_func doesn't use the default.
The choice of @ intentionally leaves out support for other STATUSMSG
(for example, AzzurraNet's bahamut 1.4 fork seemed to support + and % in
any order, contradicting the comment in the code).
I think this is a decent tradeoff, given how those servers are uncommon
and relying on +# or %# is even less common than @#.
Fixes#531
If the server didn't send it then just skip the check, the old value it
defaulted to was possibly overlapping with the CHANTYPES leading to an
incorrect behaviour. Fixes#435.
Turns out event_names_list() in irc-nicklist.c already handles this.
event_who() just ignores it, which is probably a good idea since some of
the irc servers I tested this with have a bug that results in sending
multiple prefixes in the NAMES reply but not in the WHO one (they were
forks of ircd-hybrid before 7.3.0)
And NAMES always happens, anyway. WHO is omitted sometimes for huge
channels.
The only supported methods are PLAIN and EXTERNAL, the latter is untested as of
now.
The code gets the values from the keys named sasl_{mechanism,username,password}
specified for each chatnet.
The function now skips all the leading characters that are in the STATUSMSG. If
the server didn't send the STATUSMSG option then it's assumed to be "@+" for
compatibility with bahamut 2.4 (sic).
Try to split long lines on spaces to avoid words being splitted. This
can be turned off with the option `split_line_on_space'. The code
assumes that the terminal encoding has ASCII spaces.
The userhost Irssi uses for line splitting can in some cases be wrong,
for instance when a proxy is used or when a server cloaks the hostname
without telling the client. Now Irssi always assumes the userhost is of
maximum length. 10 for username (common value) and 63 for hostname (in
RFC 2812).
