Git commit 70f0903142968ce950e7d05341fc3d9abbecddd4 by David Rosca. Committed on 19/06/2017 at 19:13. Pushed by drosca into branch 'Plasma/5.10'. Context: Return early from connectToDaemon when already connected connectToDaemon is called after 1 second delay when PulseAudio context becomes invalid, but it is also called when PulseAudio service registers on DBus. In case when PulseAudio crashes and immediately restarts, the delayed call to connectToDaemon will be called when already connected which will open second connection and leak the first one. It also leads to assert with debug build. Differential Revision: https://phabricator.kde.org/D6282 M +4 -7 src/context.cpp https://commits.kde.org/plasma-pa/70f0903142968ce950e7d05341fc3d9abbecddd4 |
