Description Warren Togami 2004-02-04 00:21:57 UTC

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.5)
Gecko/20031110 Firebird/0.7

Description of problem:
kinput2 can get stuck in a loop using 100% CPU, and you need kill -9
SIGKILL to kill it.  It prints "Warning: Select failed; error code 9"
to the terminal during this loop.

http://togami.com/~warren/archive/2004/kinput.strace.txt
strace from execve to 100% loop

This procedure below can reproduce it 100% when used from an english
US GNOME session.

[warren@ibmlaptop bin]$ set |grep LANG
LANG=en_US.UTF-8

[warren@ibmlaptop bin]$ cat ja
#!/bin/bash
kinput2 -canna &
LANG=ja_JP.UTF-8 XMODIFIERS="@im=kinput2" $@

### You can get strace output by doing this instead 
[warren@ibmlaptop bin]$ cat ja-strace
#!/bin/bash
strace -o ~/strace/kinput kinput2 -canna &
LANG=ja_JP.UTF-8 XMODIFIERS="@im=kinput2" $@
 
### Sometimes it works...
[warren@ibmlaptop bin]$ ja oowriter

[root@ibmlaptop root]# service canna restart

Comment 1 Warren Togami 2004-02-04 00:35:11 UTC

One more odd thing...
It does not fail and start looping if I launch it manually from the
terminal in that sequence rather than launch it from a shell script. 
Triggering it could be a timing issue too...

Comment 2 Akira TAGOH 2004-02-05 10:28:46 UTC

Hmm, even if I tried your step on my test machine, I couldn't
reproduce this problem... so what version of Canna are you using? I
saw similar bug on ia64 and not sure if it's the real fix, but Canna
works again by that fix.

Comment 3 Jens Petersen 2004-02-13 11:23:48 UTC

I see pretty much this behaviour every time after a clean ja install
of FC1 Test1/recent trees when running a GNOME session.

Comment 4 Nakai 2004-02-18 06:43:31 UTC

I never see this failure on my machine either. FC2 test1 or all earlier.
Works very comfortable here, and no warning.

> Warning: Select failed; error code 9

Network issue? My setting is firewall off in the office.

Comment 5 Nakai 2004-02-18 07:03:23 UTC

Yesterday I translated gnumeric ja.po for several hours on my FC2 test1,
gnome-terminal, vi and kinput2. And it didn't reproduce...

Comment 6 Nakai 2004-02-18 07:09:31 UTC

I need to add to say this prob. is reported so many times on Fedora JP
list too, but just doesn't happen for me...

Comment 7 Akira TAGOH 2004-02-19 13:31:35 UTC

Ok, I can reproduce this problem now. and hopefully this problem would
be fixed in the next release.

Comment 8 Akira TAGOH 2004-02-20 04:21:51 UTC

This problem shouldn't appears on 3.7p1-4. please test it.

Comment 9 Jens Petersen 2004-03-29 22:56:05 UTC

Thanks, I haven't seen any more hanging of kinput2 recently. :-)
