This patch fixes the following two warnings of GCC 4.2.4:
irc-channel.c: In function "IRC_JOIN":
irc-channel.c:185:
warning: "lastkey" may be used uninitialized in this function
irc-channel.c:185:
warning: "lastchan" may be used uninitialized in this function
Up to now ngIRCd accepted CR+LF as well as a single CR or LF in "non RFC
compliant" mode (the default). But ngIRCd became confused when it received
data containing mixed line endings (e. g. "111\r222\n333\r\n").
This patch enables ngIRCd (in "non RFC compliant" mode) to detect CR+LF,
CR, and LF as equally good line termination sequences and to always end the
command after the first one detected.
Some clients (for exmaple Trilian) are that ... broken to send such mixed
line terminations ...
First patch proposed by Scott Perry <scperry@ucsd.edu>,
Thanks to Ali Shemiran <ashemira@ucsd.edu> for testing!
If ngircd receives an input line like "COMMAND arg\nIRRELEVANT\r\n",
"arg\nIRRELEVANT" is passed as an argument to COMMAND. This can lead
to output like:
:ngircd.test.server 322 nick #chan 1 :
topicwithprecedingnewline
:ngircd.test.server 322 nick #nxtchan 1 :
[..]
Worse, this allows clients to piggyback irc commands, e.g.
"TOPIC #a :test\n:fake!~a@nonexistant JOIN :#a\r\n", which
causes the client to receive a JOIN command during /LIST output.
Bug reported by Scott Perry, first patch by Florian Westphal.
In addition, the "timeout" variable has been removed because it is
unnecessary today: Handle_Buffer() handles all the data it can handle,
and io_dispatch() returns immediately when new data is available. So
we don't have to double-check but better sleep. Pointed out by Florian.
This patch does significant cleanup on the join code by using strtok_r
instead of mangling strchr to parse channel names and keys in parallel when
a JOIN command contains a list of channels and keys.
Also adds an strtok_r implementation to libportab.
this also obsoletes ListenIPv4 and ListenIPv6 options.
If Listen is unset, it is treated as Listen="::,0.0.0.0".
Note: ListenIPv4 and ListenIPv6 options are still recognized,
but ngircd will print a warning if they are used in the config file.
Also, some plattforms require that ai_socktype
is set in the getaddrinfo() hints structure.
This patch adds -h and -V short options (to complement the usage).
It is based on a patch attached to Debian bug #466063, see
<http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=466063>.
Idea by Jari Aalto <jari.aalto@cante.net>,
patch adapted by Alexander Barton <alex@barton.de>.
It is hard to test this in the test suite because we 1) shouldn't rely on
previous tests populating WHOWAS and 2) don't connect a user for more than 30
seconds.
Also makes WHOWAS return ERR_NONICKNAMEGIVEN_MSG as implied by RFC.
SERVICE, SERVLIST, and SQUERY are required by RFC 2812 (it states in
section 3 that "all commands described in this section MUST be implemented
by any server for this protocol." -- So we implement them without (much)
actual functionality ...
Code cleanup and fix for Bug #83, "ngIRCd chokes on 1-character messages" in
function Handle_Buffer(): the buffer is now correctly cleared when ngIRCd
receives 1-character messages terminated with either CR or LF (in violation
to RFC 2812, section 2.3 "Messages", 5th paragraph).
Modeless channels (+channels) are described in RFC 2811;
so my modifications to
530112b114
('Add support for modeless channels')
to disable +channels for --strict-rfc configurations
were wrong. This reverts those changes.
Add support for modeless channels (+channels).
[fw@strlen.de:
- integrate test cases
- don't support +channels when compiled with --strict-rfc
- do not set +o mode for channel creator
- force +nt mode when channel is created ]
When trying to part a channel ("PART #channel") the client is not member of
the daemon now correctly reports the numeric ERR_NOTONCHANNEL (442) insted
of ERR_NOSUCHCHANNEL (403).
client.c:72:6: warning: symbol 'Max_Users' was not declared. Should it be static?
client.c:72:21: warning: symbol 'My_Max_Users' was not declared. Should it be static?
ngircd will exit if the config file cannot be opened. While
thats okay if ngircd starts up for the first time, it isn't
when we are re-reading the config file after a /REHASH or SIGHUP.
