Subject: 23.3; rcirc: INVITE command handled incorrectly
Date: Tue, 06 Sep 2011 22:29:30 +0200

This bug report will be sent to the Free Software Foundation,
not to your local site managers!
Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your report will be posted to the bug-gnu-emacs <at> gnu.org mailing list
and the gnu.emacs.bug news group, and at http://debbugs.gnu.org.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug.  If you can, give
a recipe starting from `emacs -Q':

According to RFC 2812 the INVITE command has two parameters: the user
and the channel. If I connect to any server via M-x rcirc, join a
channel and type "/invite user #channel", RCIRC incorrectly
sends "INVITE :user #channel". It should instead send "INVITE user
#channel" (note the missing colon). This leads to the server rejecting
the incorrect invite.

If Emacs crashed, and you have the Emacs process in the gdb debugger,
please include the output from the following gdb commands:
    `bt full' and `xbacktrace'.
For information about debugging Emacs, please read the file
/usr/share/emacs/23.3/etc/DEBUG.

My reading of the code seems to suggest all commands that take more than
one params must be defined by defun-rcirc-command otherwise are
incorrectly handled.

Could you try the following patch (against emacs-23.3)?

Thank you, this is the same way I patched it myself yesterday. Could you
get this patch into the official emacs repositories? It works perfectly.

Thanks for the swift help!

Thanks for confirming. Fixed in 24.1.
