Add-ons

Stability

crash data from elasticsearch is unreliable at the moment - https://bugzilla.mozilla.org/show_bug.cgi?id=1276690

Aurora

overall rate: 1.64 (orange), browser: 1.16, content: 0.48

overall crash rate is on par with that of the last cycle at this time - though content crashes are significantly lower (~0.2) & shutdownhangs are higher (0.2)

• biggest issue in danger of moving to beta is shutdownhang in mozilla::layers::CompositorBridgeParent::ShutDown (regressing in 48) https://bugzilla.mozilla.org/show_bug.cgi?id=1268559
  • this is actively worked on

Beta

overall rate: 1.16 (orange), browser: 0.96, content: 0.19

crash rate (for the browser-process) is about 0.15 lower than in the 46 rc week

crash fixes that have gone into beta 9:

• shutdownhang in nsThread::Shutdown https://bugzilla.mozilla.org/show_bug.cgi?id=1258009 -> signature still present, not sure if it has reduced though (due to the ES data issue)
• crash in TppTimerpExecuteCallback https://bugzilla.mozilla.org/show_bug.cgi?id=1270686 -> signature gone (by disabling d3d11 dxva) \o/
• crash in _dwrite_draw_glyphs_to_gdi_surface_gdi https://bugzilla.mozilla.org/show_bug.cgi?id=726206 -> looks fixed as well

Release

overall rate: 0.96 (greenish orange) startup crashes: 0.13, shutdownhangs: 0.2

• no new concerns

Nightly

• https://bugzilla.mozilla.org/show_bug.cgi?id=1276295 was causing a crash on Mac, but was quickly backed out
• https://bugzilla.mozilla.org/show_bug.cgi?id=1229252 is still hanging around, but I have an update from the developer in Comment 72
• https://wiki.mozilla.org/Platform/Uptime/Logs has the Uptime team logging information

Mobile

• Beta stability looks good
• Nightly crash that is greatly affecting the crash rate https://bugzil.la/1271103 - crash in GL code with several signatures

Release Health report

We (relman, also sheriffs) should check for test permafails well before the merge. Track them or mark as blockers if they should block the next merge. (usually works to search on "permafail", sort by last changed, and skim: https://bugzilla.mozilla.org/buglist.cgi?quicksearch=permafail&list_id=13046716 )

nightly 49: 3 blockers, 30 new regressions aurora: 3 blockers, 103 new regressions beta: 0 blockers, 20 new regressions (true number is 14)

• These bugs should block release. Are these bugs moving?

release: 2 blockers, 11 new regressions (Blockers = potential ridealongs)
