Sorry for the delay testing this, just got my dev pc back. Both test cases from the description are passing with the wily-proposed packages, version 1.6.3-1ubuntu1

There were several important leak fixes in 1.6.1, some of which also meant holding references to file descriptors around, which can result in crashes once the fd limit is hit. Upstream bugs: https://bugzilla.gnome.org/show_bug.cgi?id=755867 https://bugzilla.gnome.org/show_bug.cgi?id=756552 https://bugzilla.gnome.org/show_bug.cgi?id=756611 All of these were fixed in 1.6.1 What motivated me to investigate this bug is a 'random' crash in pidgin after several hours of leaking file descriptors, which looks exactly like bug #1479715 but happened even after applying that patch. Turns out that it wasn't pidgin holding the references that kept those file descriptors open, but it was gstreamer itself. I'd fill the whole SRU template here but i'm afraid there are too many patches that need to be applied to fix these bugs properly (some of them in gst-plugins-base, some of them in libgstreamer, and I don't know exactly which ones are needed) and anything less than updating to 1.6.1 or 1.6.2 would be wrong, IMO. The whole 1.6.x branch is bugfixes only. [Test Case] * Download https://bugzilla.gnome.org/attachment.cgi?id=313241 to playbin-leak.c * Optionally change the "a.ogg" uri to a valid path to a sound in the local system (maybe "file:///usr/share/sounds/alsa/Noise.wav"). Some leaks and warnings appear anyway even without changing this. * Build with: gcc -Wall $(pkg-config --cflags gstreamer-1.0 gtk+-3.0 glib-2.0) playbin-leak.c $(pkg-config --libs gstreamer-1.0 gtk+-3.0 glib-2.0) * Run as: GOBJECT_DEBUG=instance-count GTK_DEBUG=interactive ./a.out * Let it run, see warnings after some iterations, watch it leak. Alternatively, how i've been testing this so far, which roughly imitates the pidgin crash (but probably only applies to a subset of the leaks) * Get a ubuntu 15.10 VM without sound card (so that pulseaudio fails to play sounds) * Do this: cd /usr/share/sounds/alsa valgrind --track-fds=yes gst-play-1.0 --audiosink=pulsesink Noise.wav Noise.wav Noise.wav * File descriptors open at exit should be 4, not 10 (it leaks two for each time it plays) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gst-plugins-base1.0/+bug/1529445/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
