We emit a *lot* of runtime warnings when running debug tests. I inadvertently triggered a max log size failure during a landing this week which encouraged me to take a look at what all is being logged, and what I found was a ton of warnings (sometimes accompanied by stack traces). Most of these should probably be removed (of course if they're real issues they should be fixed, but judging by the frequency most are probably non-issues).
I'm currently cleaning up some of these, but if you happen to see something in the following list and are feeling proactive I would appreciate the help. There's even a meta bug for tracking these: https://bugzilla.mozilla.org/show_bug.cgi?id=765224 I generated this list by grabbing the logs for a recent m-c linux64 debug run, normalizing out PIDs and timestamps and then doing some sort/uniq-fu to get counts of unique lines. This is roughly the top 40 offenders: 65959 [NNNNN] WARNING: Overflowed nscoord_MAX in conversion to nscoord width: file ../../dist/include/nsRect.h, line 83 63460 [NNNNN] WARNING: NS_ENSURE_TRUE(piTarget) failed: file gdom/events/EventDispatcher.cpp, line 469 20039 [NNNNN] WARNING: 'NS_FAILED(rv)', file gdom/workers/ServiceWorkerManager.cpp, line 2529 20039 [NNNNN] WARNING: '!BasePrincipal::IsCodebasePrincipal(aPrincipal)', file gdom/workers/ServiceWorkerManager.cpp, line 2591 17784 [NNNNN] WARNING: Subdocument container has no frame: file glayout/base/nsDocumentViewer.cpp, line 2506 16322 JavaScript warning: file:///builds/slave/test/build/tests/jsreftest/tests/js1_8/extensions/regress-476427.js, line 1: JavaScript 1.6's for-each-in loops are deprecated; consider using ES6 for-of instead 14159 [NNNNN] WARNING: NS_ENSURE_TRUE(mMutable) failed: file gnetwerk/base/nsSimpleURI.cpp, line 264 14087 [NNNNN] WARNING: NS_ENSURE_SUCCESS(EnsureScriptEnvironment(), nullptr) failed with result 0x80040111: file gdocshell/base/nsDocShell.cpp, line 4592 11315 [NNNNN] WARNING: '!mMainThread', file gxpcom/threads/nsThreadManager.cpp, line 299 10574 [NNNNN] WARNING: No docshells for remote frames!: file gdom/base/nsFrameLoader.cpp, line 491 9201 [NNNNN] WARNING: have unconstrained width; this should only result from very large sizes, not attempts at intrinsic width calculation: 'psd->mIEnd != NS_UNCONSTRAINEDSIZE', file glayout/generic/nsLineLayout.cpp, line 884 9155 [NNNNN] WARNING: have unconstrained width; this should only result from very large sizes, not attempts at intrinsic width calculation: 'psd->mIEnd != NS_UNCONSTRAINEDSIZE', file glayout/generic/nsLineLayout.cpp, line 3058 9130 [NNNNN] WARNING: have unconstrained width; this should only result from very large sizes, not attempts at intrinsic width calculation: 'aISize != NS_UNCONSTRAINEDSIZE', file glayout/generic/nsLineLayout.cpp, line 160 8844 [NNNNN] WARNING: Someone passed native anonymous content directly into frame construction.
