Details

Various intermittent test failure bugs all appear to have one thing in common: Fennec crashes on startup. I believe this includes reftests, mochitests, robocop, and talos. Logcat often shows: E/GeckoLibLoad( 1536): Load nss done shortly before the crash. Stack traces are often not available, or show little more that libc and system library calls. Consider: Bug 722166 - Android tests intermittently just don't start Bug 796914 - Intermittent "talosError: 'stack found after process termination (org.mozilla.fennec: terminated by testAgent.killProcess, plugin-container: terminated by testAgent.killProcess, crashreporter: terminated by testAgent.killProcess)'" Bug 747787 - Intermittent Tegra crash in libdvm.so during tests Bug 686245 - Intermittent Android "talosError: 'browser non-zero return code (1) [browser_output.txt]'" and possibly also: Bug 810405 - Browser crashes not reported as test failures Bug 690176 - Intermittent Android "talosError: 'initialization timed out'" These bugs have thousands of tbpl failure logs. Many of these bugs contain logs that are not startup crashes, but I think startup crashes are a significant cause of the failures in most of these bugs. The absence of good stacks is a significant barrier to resolution.

E/GeckoConsole(15253): Could not read chrome manifest 'file:///data/data/org.mozilla.fennec/chrome.manifest'. is just as common, and occurs after "Load nss done".

We should make them INFOs rather than ERRORs and/or suppress them if that's the case.

The "Could not read chrome manifest" one is from the component manager, which sends it to the error console. You'll see similar messages on desktop builds, in the error console. There is no severity distinction for the component manager messages. For the others, there's a tendency to use ANDROID_LOG_ERROR for calls to __android_log_print in APKOpen.cpp which i'm not sure where they come from. The latter could be filed as a separate bug. The former would need to add severity to the component manager logging. File another bug for that if you want.

I know they are normal -- I just wanted to note that these are often the most-recent log messages before the crash. Since I cannot reproduce the crash with any regularity, I have been adding more logging to try runs. Preliminary results suggest -- but only suggest -- that the crash is in loadGeckoLibsNative.

(In reply to Geoff Brown [:gbrown] from comment #5) > Preliminary results suggest -- but only suggest -- that the crash is in > loadGeckoLibsNative. Logging shows that many of the crashes occur while loadGeckoLibsNative is executing...but sometimes the crash occurs after loadGeckoLibsNative completes, and occasionally before it starts. I'm thinking: - maybe the crash is on a different thread - maybe there are multiple causes - maybe the logging is not reliable

On a tip from glandium on an unrelated matter, I thought I would try re-creating the crash with additional logging enabled with: DEFINES += -DMOZ_DEBUG_LINKER in mozglue/linker/Makefile.in Here are 2 such crashes with the extra logging: https://tbpl.mozilla.org/php/getParsedLog.php?id=17566044&tree=Try&full=1 https://tbpl.mozilla.org/php/getParsedLog.php?id=17561794&tree=Try&full=1 Here's a

There is also bug 757405, which has a SIGSEGV blamed on libskia in reftests. In that bug, the crash happens later -- typically 5 to 10 seconds after libs are loaded.

And in bug 823535, we see the same symptoms on a pandaboard.

These unexplained crash-on-startup failures are now quite rare. Reviews of recent logs reported in bugs 796914, 722166, 686245, 816584, and 781107 show that the most frequent problems are: Bug 761987 - shutdown crashes in nsCertificate_Destroy Bug 829419 - crashes in nsDeleteDir::PostTimer Bug 830557 - java.lang.NullPointerException in IInputMethodManager There is a fairly high (temporary?) incidence of unexplained crashes on mozilla-beta: see https://bugzilla.mozilla.org/show_bug.cgi?id=686245#c1344. The remaining unexplained crash on startup logs that I can find from the last week are: https://bugzilla.mozilla.org/show_bug.cgi?id=796914#c623 (Jan 12) https://bugzilla.mozilla.org/show_bug.cgi?id=781107#c233 (Jan 10) https://bugzilla.mozilla.org/show_bug.cgi?id=816584#c49 (mozilla-aurora, Jan 7) https://bugzilla.mozilla.org/show_bug.cgi?id=816584#c50 (mozilla-aurora, Jan 7) https://bugzilla.mozilla.org/show_bug.cgi?id=816584#c51 (mozilla-aurora, Jan 7) (There are additional examples on Jan 6 and earlier; eg https://bugzilla.mozilla.org/show_bug.cgi?id=686245#c1291).
Bug 833766 contains a crash report with symbols that would look similar to our unexplained crash reports, if it did not have symbols. In that case, the top frame is /data/data/org.mozilla.fennec_morbo/lib/libmozglue.so (Java_org_mozilla_gecko_GeckoAppShell_reportJavaCrash) ... worth investigating.

Bug 837821 describes a possible cause for the remaining, unexplained startup crashes, and the test failures that initiated that bug look very similar to those we have been chasing in this bug.

We still see some crashes on test startup, but they occur much less frequently than when this bug was opened. Reporting uncaught java exceptions was particularly helpful. Dependent bugs 803158 and 824760 are still good ideas that we should pursue when priorities allow.
Assignee: gbrown → nobody
We did good work here. There are far fewer startup crashes now and this bug has outlived its usefulness.
