• Component: WebCore Misc.
• Status: RESOLVED FIXED

[Steve Block]

See http://test-results.appspot.com/dashboards/flakiness_dashboard.html#tests=fast%2Ffilesystem%2Ffile-writer-abort-depth.html

Will add a CRASH expectation for now.

Also seeing a crash in fast/filesystem/file-writer-abort.html on all Chromium Linux bots, eg http://build.chromium.org/p/chromium.webkit/builders/Webkit%20Linux%20(dbg)/builds/440

Widening expectation to Mac DEBUG.

[Vsevolod Vlasov]

fast/filesystem/file-writer-abort-depth.html also crashes on win release, win7 release.
Updated expectations:
Committed r101989: <http://trac.webkit.org/changeset/101989>

[John Knottenbelt]

This is also crashing on Linux Debug and Linux. Same call stack as above:

http://build.chromium.org/p/chromium.webkit/builders/Webkit%20Linux%20(dbg)/builds/1966/steps/webkit_tests/logs/stdio

http://test-results.appspot.com/dashboards/flakiness_dashboard.html#tests=fast%2Ffilesystem%2Ffile-writer-abort.html

Will adjust expectations to match. Kinuko, can you take a look?

[Adam Klein]

More widening, file-writer-abort-depth.html also crashes on Mac debug.

Kinuko, have you had a chance to dig into this at all?

[Adam Klein]

Here's one of the asserts from a Snow Leopard debug run:

2012-02-24 17:27:08,272 1062 single_test_runner.py:202 DEBUG worker/6 Stacktrace for fast/filesystem/file-writer-abort-depth.html:

Assertion failed: (ptr_ != NULL), function operator->, file ../base/memory/ref_counted.h, line 249.

No stack, unfortunately.

Sorry these days I haven't taken a closer look at WebKit bugs-- just filed the corresponding chromium bug since the crash is likely coming from the chrome code.

http://code.google.com/p/chromium/issues/detail?id=116639

I will take a look at the quota related DCHECK error.  I hope Eric has a better idea FileWriter.abort related errors-- or we might have introduced a new error in the recent callback refactoring.  Anyway I'll take a look.

[Kinuko Yasuda]

After landing http://crrev.com/136513 it looks fine now.

Now it looks pretty stable in terms of CRASH, but it seems to be occasionally seeing timeouts.  I removed CRASH expectations from test_expectations.txt.  As for timeouts I'll keep an eye on it.

[Kinuko Yasuda]

Now all tests look green.  Closing!
