23.1; Emacs daemon gets killed by emacsclient -c

23.1; Emacs daemon gets killed by emacsclient -c

[Fabian Ezequiel Gallina]

Hi,

My Emacs daemon gets killed after using emacsclient -c for third
time.

I really don't know how to give a better traceback for this. Any
recommendations are appreciated.

Here is how I reproduce the bug:


[fgallina@cuca ~]$ emacs --daemon -Q
("emacs" "-Q")
Starting Emacs daemon.
[fgallina@cuca ~]$ emacsclient -t
[fgallina@cuca ~]$ emacsclient -t
[fgallina@cuca ~]$ emacsclient -t
[fgallina@cuca ~]$ emacsclient -t
[fgallina@cuca ~]$ emacsclient -t
[fgallina@cuca ~]$
[fgallina@cuca ~]$ emacsclient -c
Waiting for Emacs...
[fgallina@cuca ~]$ emacsclient -c
Waiting for Emacs...
[fgallina@cuca ~]$ emacsclient -c
Waiting for Emacs...
[fgallina@cuca ~]$ ps axu | grep -i emacs
fgallina  4236  0.0  0.0  91080   888 pts/1    S+   05:37   0:00 grep -i emacs


The third time I use emacsclient -c, after the "Waiting for Emacs
message" is displayed,
nothing happens. So I checked and the Emacs daemon process was
not running anymore.

The funny thing is that emacsclient -t works flawlessly. I'm only
having this problem when I run emacsclient -c.


I'm running Emacs 23.1 on Fedora 11.


Thanks,
Fabián E. Gallina.

FWIW, I was unable to reproduce this behavior. I tried opening a bunch
of Emacs clients, both with -t and -c, without anything strange
happening.

If I don't close the frames, then it works. The problem happens if I
actually do this:

[fgallina@cuca ~]$ emacsclient -c
Waiting for Emacs...

# Close the frame with C-x 5 0

[fgallina@cuca ~]$ emacsclient -c
Waiting for Emacs...

# Close the frame with C-x 5 0

[fgallina@cuca ~]$ emacsclient -c
Waiting for Emacs...

# The Frame does not opens because Emacs daemon was killed.

I can reproduce this every time, and always happens on the third attempt.

Still no luck reproducing it on my system.

  In these cases, strace can be useful to see what is the last thing that the process did before dying.
Try „strace ls“, „strace emacs --daemon“, „strace emacsclient“ etc. And „man strace“ for more information.
  gdb can also help to see what is Emacs doing, but it may be harder to extract the information.

I can't reproduce it on my Fedora 11 machine.
Can you recompile using:
configure --with-x-toolkit=lucid

and see if you get the problem in that configuration.

Do you use gtk-qt-engine, by chance?

Hi Dan,

Compiled with lucid worked perfect, however I would like to able to
track down why is failing with gtk.

No, I'm not.

I'm running Gnome 2.26.3 on Fedora 11 (x86_64).

I'm running Fedora 11 Gnome, and have reproduced this bug. Recompiling with
lucid does indeed fix the situation.

Also, this appears to be specific to Fedora 11 Gnome. I tried a gtk-compiled
Emacs 23.1 on KDE and xfce and both worked fine.

If it's the same bug as
http://lists.gnu.org/archive/html/emacs-devel/2009-03/msg00281.html,
you probably need update libcanberra.
