Irssi 0.8.15 built from FreeBSD Ports segfaults at random times on both FreeBSD 9.0-RELEASE and 9.1-RC1 (arch is i386). The backtrace for each segfault is somewhat similar.

No scripts running (unless something is installed automatically from the default port), and all I've been doing is idling, really.

Irssi can crash if the term ysize is lowered during the irssi initialization. The proposed fix is attached. Original report:
http://bugzilla.redhat.com/show_bug.cgi?id=796457

According to OpenSSL library documentation[1], calling SSL_CTX_set_options with SSL_OP_NO_SSLv2 is sufficient to disable SSLv2. ORing that value with SSL_OP_ALL turns on a whole host of workarounds. These workarounds actually degrade the security of OpenSSL. A side-effect is that it breaks modern TLSv1.1.

With SSL_OP_ALL | SSL_OP_NO_SSLv2, connecting to a TLS v1.1 server using FIPS algorithms results in "unknown protocol" (Attached: irssi-r5136.patch)

With SSL_OP_NO_SSLv2, connecting to a TLSv1.1 server is successful (Attached: irssi-r5136-revised.patch)

[1] OpenSSL Documentation, SSL_CTX_set_options: http://www.openssl.org/docs/ssl/SSL_CTX_set_options.html

When there are no completions and the user types "/COMPLETION", the resultant message suffers from a slight bout of poor grammar.

00:12 Irssi: There's no completions

The proper phrasing should be "There are no completions", or if the contraction is really desirable, "There're no completions". The former is a bit awkward to look at, unfortunately.

When passing a reference that isn't an arrayref to register_theme in the Perl API,
the process segfaults. This is caused by insufficent validation of the passed
argument. The proposed patch verifies that "formats" is an array reference before
continuing.

I have occasion to use two different config files for irssi, which is currently a bit of a pain to do (renaming the file I want each time, keeping track of which file is currently the actual config...)
It would be much simpler to be able to start irssi with a command line option allowing me to name the config file I want it to use for that session.

Thanks, MildBill

It seems that logs are created with mode 0600 by default, at least on my Debian system. The documentation in docs/help/in/log.in should be updated to say "Default is 0600" instead of 0644.

This page says default is 0600: http://irssi.org/documentation/settings

When adding an IRC Bouncer as a server such as ZNC, with multiple connections with different chatnets, I get this error:
Disconnecting dupe IRC server

For instance, if I add 2 seperate /network entries "net1" and "net2" and add 2 /server entries on the same IP using each of the aforementioned networks, the server will disconnect from one of them.

REQUEST server aliasing for configuration file, EXAMPLE:


{
alias = "SOME_ALIAS"
address = "123.123.123.123";
chatnet = "net1";
port = "1234";
password = "name:pass";
use_ssl = "no";
ssl_verify = "no";
autoconnect = "yes";
},

If you connect with /connect -! , the network's autosendcmd is not sent. Having no auto join channels enabled should not prevent autosendcmd from being sent.
