Ever since they were turned on this morning, every WinXP debug mochitest-1 has been orange like http://tinderbox.mozilla.org/showlog.cgi?log=Firefox/1299774166.1299776765.2061.gz Rev3 WINNT 5.1 mozilla-central debug test mochitests-1/5 on 2011/03/10 08:22:46 s: talos-r3-xp-015 36154 ERROR TEST-UNEXPECTED-FAIL | /tests/content/canvas/test/webgl/test_webgl_conformance_test_suite.html | Test expected to fail, but passed: conformance/canvas-test.html So, I pushed http://hg.mozilla.org/try/rev/58bba9e5bb04 to try, to only expect it to fail in WinXP opt, and for my trouble got http://tinderbox.mozilla.org/showlog.cgi?log=MozillaTry/1299822320.1299824852.17505.gz Rev3 WINNT 5.1 tryserver debug test mochitests-1/5 on 2011/03/10 21:45:20 s: talos-r3-xp-045 36059 ERROR TEST-UNEXPECTED-FAIL | /tests/content/canvas/test/webgl/test_webgl_conformance_test_suite.html | Test failed, "pixels are 0,255,255,159 expected 0,0,0,0" (URL: conformance/canvas-test.html) No idea whether that's just awful coincidence, and it's really random whether it fails or not, or a sign that there's a bug in the harness' ability to tell whether something that was supposed to fail did fail.
Random. Ran my patch three more times, got one more failure with "Test failed, "pixels are 253,251,253,156 expected 0,0,0,0" (URL: conformance/canvas-test.html)" and two successes, so we either need to give the harness understanding of random-if, or just skip running it completely.
But just being frequently orange isn't enough to let this hold an entire test suite hostage, I'm unhiding the WinXP Md1.

Whiteboard: [perma-orange] → [orange]
This is totally unacceptable. Benoit, can you please investigate? I'm afraid that I'm going to have to submit a patch to disable WebGL on XP if this test keeps failing this way, since I bet money that this is a code problem.

Well, this <http://mxr.mozilla.org/mozilla-central/source/content/canvas/test/webgl/test_webgl_conformance_test_suite.html?force=1#360> tells me that we're kind of working around an intermittent failure by pretending that the test always fails, and that's apparently the wrong assumption. This looks like a very bad practice to me. :(

Unfortunately this won't be fixed by updating ANGLE; it just seemed like it would.

Since the canvas test can't be relied upon on Windows XP, let's just ignore the results of that test. On try: http://tbpl.mozilla.org/?tree=MozillaTry&rev=cda3bc3bbaa6

Comment on attachment 524935 [details] [diff] [review] ignore canvas-test on XP OK, having a list of ignored tests is a good idea anyway.

I'd appreciate if you guys can debug this when you're back in the office. I really want to see what's the cause of the failure here. Thanks!

(In reply to comment #95) > Test disabled in http://hg.mozilla.org/mozilla-central/rev/7a0acca5854b FWIW, comment 96, 97 and 98 happened on revisions before this one.
No longer depends on: 646229
I think we should disable this particular test on 2.0
The intermittent orange has been fixed by disabling the test. Please file a new bug for investigating why it happens if needed.
