#4 0x000056004c7cf927 in pidgin_sound_play_event (event=PURPLE_SOUND_SEND)
at /build/pidgin-hiYwOJ/pidgin-2.10.11/./pidgin/gtksound.c:616
[Impact]
* Each sound played will leak a file descriptor.
* Crash (null pointer dereference) after playing sounds roughly 1000 times (depending on fd limit)
* Depending on the amount of activity, this can mean every few hours for some users (it's once for each received or sent message)
[Test Case]
1. Set the file descriptor limit low enough to be able to login, plus a few extra. "ulimit -Sn 20" works for me
2. Start pidgin
3. Tools menu -> preferences -> sounds tab
4. Click "preview" 10 times or so
5. Acquire crash
[Regression Potential]
* The fix consists in adding two lines, returning FALSE when a sound finishes playing or when an error happens, which tells gstreamer to free those file descriptors, so it's highly unlikely that this could make things worse.
* A user who reported this bug yesterday was given a .deb file with the fix, who also distributed that fixed .deb to other 50 users who also had the issue in ubuntu wily. Everyone is happy now.
[Other Info]
* This fix will be included in pidgin 2.10.12, set to release very soon.
* The bug originally happened because of the backported gstreamer 1.0 patch that was also introduced in post-2.10.11 development versions. |
