117063 2013-05-31 01:29:30 -0700 [GTK] Weird behaviour and no clues to the user when the shared memory file can't be opened 2013-06-07 09:37:35 -0700 1 1 1 Unclassified WebKit WebKit2 528+ (Nightly build) Unspecified Unspecified RESOLVED FIXED P2 Normal --- 0 eocanha webkit-unassigned andersca benjamin cgarcia commit-queue eocanha oldest_to_newest 895809 0 eocanha 2013-05-31 01:29:30 -0700 When running a non-debug build of Gtk MiniBrowser, I can only see a big grey rectangle in the place where the web content should be. If I press right click at some place in the grey area, I can see different context menus depending on the contents that should be there if the browser worked properly. No clue about what's causing the behaviour. After some investigation, gathered some important facts: - I was running MiniBrowser in a chroot environment - That chroot environment didn't have /dev/shm or /run/shm mounted - The actual problem was in this piece of code from SharedMemory::create(), in Source/WebKit2/Platform/unix/SharedMemoryUnix.cpp: fileDescriptor = shm_open(tempName.data(), O_CREAT | O_CLOEXEC | O_RDWR, S_IRUSR | S_IWUSR); ... if (fileDescriptor == -1) { return 0; } The real issue is that the user using a normal build has no clue at all about what's causing the problem. 895812 1 203422 eocanha 2013-05-31 01:38:25 -0700 Created attachment 203422 Patch 895824 2 203422 cgarcia 2013-05-31 01:53:25 -0700 Comment on attachment 203422 Patch LGTM 898208 3 203422 commit-queue 2013-06-07 09:37:33 -0700 Comment on attachment 203422 Patch Clearing flags on attachment: 203422 Committed r151324: <http://trac.webkit.org/changeset/151324> 898209 4 commit-queue 2013-06-07 09:37:35 -0700 All reviewed patches have been landed.
