Didn't verify by changing the relevant prefs, but this should be since cache2 is not enable - bug 1021843. 6:40:10 INFO - NS_ERROR_NOT_IMPLEMENTED: Component returned failure code: 0x80004001 (NS_ERROR_NOT_IMPLEMENTED) [nsICacheStorageService.pinningCacheStorage] 06:40:10 INFO - getCacheStorage@C:/slave/test/build/tests/xpcshell/tests/netwerk/test/unit/head_cache.js:53:1 06:40:10 INFO - asyncOpenCacheEntry/CacheListener.prototype.run@C:/slave/test/build/tests/xpcshell/tests/netwerk/test/unit/head_cache.js:90:21 06:40:10 INFO - asyncOpenCacheEntry@C:/slave/test/build/tests/xpcshell/tests/netwerk/test/unit/head_cache.js:95:4 06:40:10 INFO - run_test@C:/slave/test/build/tests/xpcshell/tests/netwerk/test/unit/test_cache2-30c-pinning-deferred-doom.js:60:1 06:40:10 INFO - _execute_test@C:\slave\test\build\tests\xpcshell\head.js:514:7 06:40:10 INFO - @-e:1:1 06:40:10 INFO - PROCESS | 6384 | [6384] WARNING: TimelineConsumers could not be initialized.: file c:/builds/moz2_slave/tb-c-cen-w32-d-000000000000000/build/mozilla/docshell/base/timeline/TimelineConsumers.cpp, line 63 06:40:10 INFO - PROCESS | 6384 | [6384] WARNING: OOPDeinit() without successful OOPInit(): file c:/builds/moz2_slave/tb-c-cen-w32-d-000000000000000/build/mozilla/toolkit/crashreporter/nsExceptionHandler.cpp, line 2792 06:40:10 INFO - PROCESS | 6384 | [6384] WARNING: XPCOM objects created/destroyed from static ctor/dtor: file c:/builds/moz2_slave/tb-c-cen-w32-d-000000000000000/build/mozilla/xpcom/base/nsTraceRefcnt.cpp, line 167 06:40:10 INFO - PROCESS | 6384 | [6384] WARNING: XPCOM objects created/destroyed from static ctor/dtor: file c:/builds/moz2_slave/tb-c-cen-w32-d-000000000000000/build/mozilla/xpcom/base/nsTraceRefcnt.cpp, line 167 06:40:10 INFO - PROCESS | 6384 | nsStringStats 06:40:10 INFO - PROCESS | 6384 | => mAllocCount: 4652 06:40:10 INFO - PROCESS | 6384 | => mReallocCount: 255 06:40:10 INFO - PROCESS | 6384 | => mFreeCount: 4652 06:40:10 INFO - PROCESS | 6384 | => mShareCount: 4695 06:40:10 INFO - PROCESS | 6384 | => mAdoptCount: 261 06:40:10 INFO - PROCESS | 6384 | => mAdoptFreeCount: 261 06:40:10 INFO - PROCESS | 6384 | => Process ID: 6384, Thread ID: 732 06:40:10 INFO - <<<<<<< 06:40:10 INFO - TEST-START | netwerk/test/unit/test_cache2-30b-pinning-storage-clear.js

Set the prefs to actually use cache2 before testing these. cache2 isn't in use in Thunderbird yet so therefore we get errors here

Michal: ping on the review

Comment on attachment 8684606 [details] [diff] [review] bug1221758_cache2_tb_testfailures.patch Review of attachment 8684606 [details] [diff] [review]: ----------------------------------------------------------------- Instead of forcing the test to use cache2, the test simply shouldn't run with the old cache. I.e. there should be a check like in a lot of other cache2 specific tests: if (!newCacheBackEndUsed()) { do_check_true(true, "This test checks only cache2 specific behavior."); return; }

Updated, thx!

Hello, this has caused xpcshell bustage.

https://hg.mozilla.org/integration/mozilla-inbound/rev/fc9023a0d7619127c607db4e06986c8979c949ad Backed out changeset 80a79987da8b (bug 1221758) for xpcshell bustage on CLOSED TREE

Ah sorry about that. TEST-UNEXPECTED-FAIL | netwerk/test/unit_ipc/test_cache_jar_wrap.js | xpcshell return code: 0 ReferenceError: newCacheBackEndUsed is not defined at /builds/slave/test/build/tests/xpcshell/tests/netwerk/test/unit/test_cache_jar.js:92 Return code: 1

Make the head_cache2.js functions accessible for netwerk/test/unit_ipc/test_cache_jar_wrap.js
