Package: tumbler
Version: 0.1.30-1+b1
Severity: normal
Hello, I'm copying the contents of
https://bugzilla.xfce.org/show_bug.cgi?id=11244 here,
in the hope that is a debian-specific bug, or that the maintainer could help
fixing it.
I've been told on #xfce on IRC that some people are unable to reproduce this
bug.
Hi, this is along standing problem with tumbler. The tumblerd process to uses
huge amounts of RAM (more than 800 Mb) when thumbailing some files, like the
attached animated GIF file (only 458kb). This also consumes a large percentage
of IO (70% is common), and increases CPU load (about 60% on my Centrino
@1.66GHz)
Bugs that look related:
* https://bugzilla.xfce.org/show_bug.cgi?id=9954
* https://bugzilla.xfce.org/show_bug.cgi?id=9231
* https://bugzilla.xfce.org/show_bug.cgi?id=10876
* https://bugzilla.xfce.org/show_bug.cgi?id=4955
* https://bugzilla.xfce.org/show_bug.cgi?id=7494
This is rather serious as it
* makes the system unresponsive (hard to even move the mouse cursor) due to
intense swapping and IO.
* is triggered by merely browsing a directory with such a file in it.
* can be used to DoS a machine (simply send them that file).
Tested on several machines, i386 and amd64 architectures, up to tumbler
0.1.30-1+b1 (Debian testing/unstable) Hope there's something to be done. Maybe
put an arbitrary limit on the memory tumblerd is allowed to use
Thanks

Still no reply on this?
I've hit this bug a lot during the past month, I now always have a terminal
windows open with 'killall -9 tumblerd' ready to hit enter when I browse a
directory containing gif files.
Please have a look at this. Disabling thumbnailing for gifs would be
acceptable. Or use another thumbnailer that doesn't have this bug.
Bumping importance so hopefully this gets noticed.
Thanks in advance.

Attaching the strace output of the operation: http://pastebin.com/jAk1H1Tz
Steps to reproduce:
* Download the example gif in a ~/test/ directory with 'wget
https://bugzilla.xfce.org/attachment.cgi?id=5699 -O crash.gif'
* Prepare a terminal window with 'killall -9 tumblerd'
* find tumberd's pid, attach strace to it with 'strace -p $pid' (prints up to
line 3 in the output)
* run 'thunar ~/test/', strace prints lines starting from 4
* try to refocus the terminal window with the killall command despite furious
lag, hit enter.
I had an htop window displayed that showed tumblerd spiking to 63%+ of RAM
usage. Unreliable as it was not refreshing.

(By the way, I've tried disabling GIF thumbnailing as a workaround, by editing
/etc/xdg/tumbler/tumbler.rc, but disabling the relevant thumbnailer
[PixbufThumbnailer]
also disables thubnailing for other image formats, which works fine and is
useful)
Hope this can be fixed.
Thanks again
