On the Android 2.3 emulator, many of the tests in content/media/webaudio fail intermittently (sometimes frequently) and have been disabled for the initial run of these tests. https://tbpl.mozilla.org/php/getParsedLog.php?id=35086627&tree=Ash&full=1#error0 19:30:59 INFO - 1210 INFO TEST-INFO | MEMORY STAT heapAllocated after test: 30690144 19:30:59 INFO - 1211 INFO TEST-END | /tests/content/media/webaudio/test/test_bug866737.html | finished in 3389ms 19:30:59 INFO - 1212 INFO TEST-START | /tests/content/media/webaudio/test/test_bug867089.html 19:30:59 INFO - 1213 INFO TEST-INFO | MEMORY STAT vsize after test: 459980800 19:30:59 INFO - 1214 INFO TEST-INFO | MEMORY STAT residentFast after test: 160903168 19:30:59 INFO - 1215 INFO TEST-INFO | MEMORY STAT heapAllocated after test: 33608032 19:30:59 INFO - 1216 INFO TEST-END | /tests/content/media/webaudio/test/test_bug867089.html | finished in 3587ms 19:30:59 INFO - 1217 INFO TEST-START | /tests/content/media/webaudio/test/test_bug867104.html 19:30:59 INFO - 1218 ERROR TEST-UNEXPECTED-FAIL | /tests/content/media/webaudio/test/test_bug867104.html | Test timed out. 19:30:59 INFO - 1219 INFO TEST-INFO | MEMORY STAT vsize after test: 474988544 19:30:59 INFO - 1220 INFO TEST-INFO | MEMORY STAT residentFast after test: 194437120 19:30:59 INFO - 1221 INFO TEST-INFO | MEMORY STAT heapAllocated after test: 69712092 19:30:59 INFO - 1222 INFO TEST-END | /tests/content/media/webaudio/test/test_bug867104.html | finished in 320306ms 19:30:59 INFO - 1223 INFO TEST-START | /tests/content/media/webaudio/test/test_bug867174.html 19:30:59 WARNING - TEST-UNEXPECTED-FAIL | /tests/content/media/webaudio/test/test_bug867174.html | application timed out after 330 seconds with no output 19:30:59 INFO - INFO | automation.py | Application ran for: 0:43:58.681137 Logcat often has messages like: 19:31:00 INFO - 02-21 19:23:26.606 W/AudioFlinger( 37): write blocked for 72 msecs, 549 delayed writes, thread 0xc658 before these failures, although sometimes (as here) not immediately before the failure.

Most Android 2.3 mochitests are running fine now. The webaudio tests are disabled. I tried enabling them, but intermittent failures persist: https://tbpl.mozilla.org/php/getParsedLog.php?id=40285748&tree=Try&full=1

Hi JW -- I saw you were trying to fix the tests on bug 981898 for Android 2.3. Can you tell me (approximately) how much work it would be to fix the tests on this bug?

Hi Maire, Please see bug 981898 comment 6.

Following resolution of bug 1020227, I found these were running reliably: https://tbpl.mozilla.org/?tree=Try&rev=f0c43f76559e https://tbpl.mozilla.org/?tree=Try&rev=11b7993b83b7 except for test_audioBufferSourceNodeOffset.html, which failed frequently due to bug 906752. content/media/webaudio/test re-enabled on Android 2.3, and test_audioBufferSourceNodeOffset.html disabled on Android: https://hg.mozilla.org/integration/mozilla-inbound/rev/0f315a493129
