Hi there,

The problem is:

Everything went fine until I tried to change my nickname.

Now my altered nickname is stuck in the cache and I can no longer connect to the server.

I get this error:

15:42 -!- Irssi: Looking up irc.deoxy.org

[(status)]

after these commands:
$ irssi

In application:
[(status)] /server irc.deoxy.org
[(status)] /connect irc.deoxy.org
[(status)] /join thomasdelbeke

Chatzilla works just fine in the mean time.

Note that the man page and --help instructions need to be updated. These instructions just do not work:

[tdflanders (thomasdelbeke)]

This is the very command (copied from irssi --help), that rendered the application inoperable:

thomas@thomas-laptop:~$ irssi -n --nick=thomasdelbeke

The rest does not work either though.

Inside the application, /help lists a whole lot of commands that DO work.

I attach gdb, valgrind and strace, but I seem to mis debug syms. Please tell me which ones, so I can do a backtrace. This is easily reproducible.

(strace just hangs)

[C. Cooke (ccooke)]

Hi, thanks for taking the time to open a bug report.

You said the help instructions didn't work - does that mean you tried 'irssi -n thomas' (or some other name that only uses alphanumerics)?

[C. Cooke (ccooke)]

Ah, I may see.

The options in the help are giving two possible ways to set the name: "-n <name>" or "--name=<name>". If you use both, it may not work correctly.

[tdflanders (thomasdelbeke)]

Correct,

this solved it:

irssi -n thomasdelbeke
/quit

Now it is out of the cache. I can again just run irssi. Also irssi --nick=thomasdelbeke and later irssi gives no problems. So we can close this one down.

It still should not stay in the cache I think. Also the alphanumeric warning is flawed. I just did irssi -n --nick=<name>. Wishlist?

BTW, both gdb and valgrind give a memory leak (see attachment) after installing some <package>-dbgsym's.

Cheers,

Thomas

[tdflanders (thomasdelbeke)]

Oops,

A little too soon here:

A watched in Chatzilla. My name got displayed as: thomasde1beke instead of thomasdelbeke. So that is a number one (1) instead of a letter "l", lima. I am sure it is not a typo.

I can reproduce it each way:
irssi
/server irc.deoxy.org
/join #thomasdelbeke
<OR>
irssi -n thomasdelbeke
/server irc.deoxy.org
/join #thomasdelbeke
<OR>
irssi --nick=thomasdelbeke
/server irc.deoxy.org
/join #thomasdelbeke
<OR>

However, when I open:
firefox > Tools > Chatzilla
and then enter:
/server irc.deoxy.org
/join #thomasdelbeke

I can log in correctly. Somehow there is an automated substitution of the letter l by a number 1. I can do another backtrace if you want, if this is hardware specific.

Again,

when doing irssi -n l I cannot trigger a crash, but in Chatzilla I see nickname L instead of l. When doing irssi -n thomasdelbeke, I do get a crash:

 Erm, that's a wrong usage, that would try to set the nickname to
--nick=<name> which is obviously not alphanumeric and not allowed by IRC
servers.

 Hope that helps. :)
