74078 2011-12-08 05:13:51 -0800 [Qt] Shared memory should use SHM instead of tmpdir 2011-12-15 04:38:29 -0800 1 1 1 Unclassified WebKit WebKit2 528+ (Nightly build) Unspecified Unspecified RESOLVED FIXED P2 Normal --- 0 allan.jensen webkit-unassigned hausmann ostap73 webkit.review.bot oldest_to_newest 517318 0 allan.jensen 2011-12-08 05:13:51 -0800 Originally seen as one of the causes of NB#240753 Shared memory uses tmpdir which causes a crash if the filesystem tmpdir resides in fills up. Switching the shared memory implementation from tmpdir to SHM provides a stability and performance improvement. 517329 1 118370 allan.jensen 2011-12-08 05:31:41 -0800 Created attachment 118370 Patch 517333 2 118370 kenneth 2011-12-08 05:38:22 -0800 Comment on attachment 118370 Patch Looks good 517353 3 118377 allan.jensen 2011-12-08 06:08:22 -0800 Created attachment 118377 Patch 518187 4 118377 webkit.review.bot 2011-12-09 01:51:40 -0800 Comment on attachment 118377 Patch Rejecting attachment 118377 from commit-queue. sandfeld@kde.org does not have committer permissions according to http://trac.webkit.org/browser/trunk/Tools/Scripts/webkitpy/common/config/committers.py. - If you do not have committer rights please read http://webkit.org/coding/contributing.html for instructions on how to use bugzilla flags. - If you have committer rights please correct the error in Tools/Scripts/webkitpy/common/config/committers.py by adding yourself to the file (no review needed).

We should simply be using shm_open/shm_unlink for SharedMemoryUnix.cpp. 521717 9 allan.jensen 2011-12-15 00:36:57 -0800 I agree. I only made it QT specific because I didn't have the setup to compile and test for GTK. It should be very easy for a GTK developer to remove the IFDEFs and join the code. 521831 10 hausmann 2011-12-15 04:38:29 -0800 (In reply to comment #9) > I agree. I only made it QT specific because I didn't have the setup to compile and test for GTK. It should be very easy for a GTK developer to remove the IFDEFs and join the code. I have filed bug #74602 for this.
