There's several problems with how abrt interacts with GNOME and Wayland; I'm not sure to what extent these distort the figures. First problem: abrt considers *lots* of actually-unrelated crashes to be duplicates, because their tracebacks look similar - this happens because glib has a special 'logging' function which actually means (more or less) 'die intentionally, with this log message'. abrt tends to interpret many bugs that crash along that path as dupes of each other, even if the actual cause of the crash - whatever triggers that special log message call - is different in each case. I've filed a couple of variants of this at: https://bugzilla.redhat.com/show_bug.cgi?id=1509086 Second problem: I *think* there's a similar issue with the recently- introduced `dump_gjs_stack_on_signal_handler` path; I've found at least some cases of apparently-unrelated bugs being marked as dupes due to that path. Details: https://github.com/abrt/satyr/issues/272 Third problem: abrt doesn't do a very good job of reporting any crash that's caused by Xwayland dying. All you get is a backtrace that basically tells you "Xwayland crashed", but no useful information about why. Sometimes the system log extract that abrt captures happens to shed some light on the reason, but sometimes it doesn't. Details: https://github.com/abrt/satyr/issues/271 I did some cleanup on false dupes and things caused by these problems, but it's necessarily incomplete, and I know more dupes have been filed since I did the cleanup... -- Adam Williamson Fedora QA Community Monkey IRC: adamw | Twitter: AdamW_Fedora | identi.ca: adamwfedora http://www.happyassassin.net _______________________________________________ devel mailing list -- devel@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to devel-leave@xxxxxxxxxxxxxxxxxxxxxxx
