This avoids undefined behavior in functions that call these split
functions and expect an array back instead of just a NULL pointer.

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.

SASL: handle fragmentation
|
|
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.

Closes #169
|
|
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.

Fail instead of crash, if irc_server_connect is called without object.
(#208)
|
|
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).

Just a string replacement (but i did check every one of them)

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).

Add line splitting logic to commands `/me' and `/action'.
|
|
ferret, the author of `splitlong-safe.pl' pointed out that `userhostlen'
should not only contain the maximum length of the hostname, but also the
maximum length of the username. Now 10 is used as the maximum username
length as a fallback. (`splitlong-safe.pl' uses the same limit.)
The username limit isn't defined in the standard, but 10 is common on
many networks. The odds that something goes wrong here is low, as
1) the fallback limit is only used when the user has not yet joined a
channel
2) the maximum hostname length (63) gives some error margin as the
hostname usually is shorter
|
|
`split_line_end' could force lines to be unnecessarily split. This
commit fixes the problem by making sure that the last line isn't shorter
than `split_line_end'.
|
|
Add settings `split_line_start' and `split_line_end' analogous to
`splitlong_line_start' and `splitlong_line_end' in `splitlong.pl'. The
prefixes and suffixes are concatenated with a wrapper function to keep
`recode_split' and `strsplit_len' simple.

This commit adds handling of long IRC messages to the core. In contrast
to the `splitlong.pl' plugin, multi-byte encoded and recoded messages
are properly split.
To allow for this, a new function has been added to the server struct:
`split_message'. `split_message' returns a string array with the message
splitted to substrings of a length that the server can handle. If a
protocol module doesn't have any limit, it can simply return a singleton
array with a copy of the message.
The `MSG' chat command now calls `split_message' before `send_message',
and emits `message own_public' / `message own_private' with each
substring, so that the string splitting will be visible in the UI.
`split_message' in the IRC module uses `recode_split' which in turn uses
iconv to properly split multi-byte encoded (and recoded) messages.

dancer and possibly others"
This is no longer relevant and most ircds now send a correct isupport
message.
This reverts commit b832f1f7b2c4a692786d5d52904a2bdf4d14354f.
