Subject: lightdm-gtk-greeter: leaking memory

Date: Tue, 07 Jan 2014 21:49:48 +0100

Package: lightdm-gtk-greeter
Version: 1.6.1-4
Severity: normal

USER       PID %CPU %MEM    VSZ   RSS TTY      STAT START   TIME COMMAND
root     27352  0.2  0.8 143040 36104 tty7     Ss+  17:25   0:22 /usr/bin/X :0 -auth /var/run/lightdm/root/:0 -nolisten tcp vt7 -novtswitch
lightdm  27370  0.4  0.6 401064 26404 ?        Ssl  17:25   0:45 /usr/sbin/lightdm-gtk-greeter

An hour later...

root     27352  0.2  0.9 145452 38476 tty7     Ss+  17:25   0:30 /usr/bin/X :0 -auth /var/run/lightdm/root/:0 -nolisten tcp vt7 -novtswitch
lightdm  27370  0.4  0.6 402252 27460 ?        Ssl  17:25   1:01 /usr/sbin/lightdm-gtk-greeter

That's about +1MB RSS per hour for lightdm-gtk-greeter, and about +2MB RSS per
hour for X. Last time I went on a 2 week vacation, when I returned greeter had
half a gig RSS. Forgot to screenshot it.

To make matters worse, X is not releasing allocated memory after login. It
persists until the end of the session, when it is finally restarted.

I tried reverting to the default theme (Adwaita), but it doesn't change a
thing (still leaks).

Finally, CPU usage is also a bit problematic. I suspect it is somehow connected
to the memory leak. Eventhough 0.2 - 0.4% CPU is not much, it's still unexpected
for a display manager. Not to mention that it doesn't allow CPU on an otherwise
dormant machine to go to deep sleep and probably wastes a lot of power.

Can you provide a valgrind log? See
http://valgrind.org/docs/manual/quick-start.html

I replaced `start-stop-daemon --start --quiet --pidfile 
/var/run/lightdm.pid --name lightdm --exec $DAEMON -b|| echo -n " 
already running"' in /etc/init.d/lightdm with `valgrind --leak-check=yes 
$DAEMON', fired up screen and run `/etc/init.d/lightdm start >out 2>err' 
in it. Will send you the files in about an hour, after I ctrl-C it.

I hope that's what you need? Never run valgrind before. :P

Log attached. Though, I'm not sure this will be helpful. This is 
valgrind log of lightdm daemon, but it's not daemon that is leaking, but 
gtk-greeter! I don't know how to run valgrind on gtk-greeter, which is 
started internally by lightdm. Please instruct.

Actually, I know! I replaced lightdm-gtk-greeter binary with a shell 
script wrapper which will invoke real binary under valgrind. Another hour...

Thanks, I'll take a look with upstream and see if we can find something.

It seems that some leaks were fixed in 1.7.0. Can you try the one in
experimental?

Sure thing. Wasn't even aware there was an experimental version. Will 
test it later today and report my findings.

Valgrind log from 2 hour run of 1.7.0 with stock configuration for the 
sake of testing. Leaks still there, I'm afraid.

Hi,

Please install debug symbols for glib and gdk and then rerun valgrind with:
--leak-check=full --show-leak-kinds=all

Also please note lightdm-gtk-greeter is expected to leak exactly one
X11 pixmap which contains the user's wallpaper and sticks around after
the greeter exits.

In order to do that on Debian, you'll need libglib2.0-0-dbg and
libgtk-3-0-dbg.

Packages with symbols installed, new valgrind log attached. Still 
default config, run greeter for about 7-8 hours.

This is the background pixmap. 1920*1080*4 = 8,294,400. This is
intentionally "leaked".

Thank you Alistair, you're quick! Yves-Alexis, let me know when you have 
uploaded version with this fix included, whenever it is (no hurry), so I 
can retest and report.

You can close this bug, now. I don't see any memory leaks in the latest 
sid versions of lightdm-gtk-greater. Thanks!
