[Ben Turner (not reading bugmail, use the needinfo flag!)]

Wait, correct me if I'm wrong here, but this test crashed once for running out of memory and so the decision was to disable the entire indexedDB OOP test suite on android?

Comment 5

[Ed Morley [:emorley]]

As a followup to the 60 reported failures (bearing in mind only 10% on android failures get starred precisely, the rest generically so, due to the quantity and poor parsing of failures) in bug 775053, yes.

Um, that's a totally different test:

dom/devicestorage/ipc/test_ipc.html vs. indexedDB/ipc/test_ipc.html

Comment 7

[Ed Morley [:emorley]]

Bug 775053 caused the suite to halt before we reached this test, which is why there is only one occurrence in this bug (I believe there were others that ended up being starred generically and not posted here); trying to remember back to what was discussed on IRC, I believe we thought this test was exhibiting the same behaviour & so should be disabled as well. I guess we could re-enable for a day and see how frequent it is. 

Though I'm pretty much at the point of hiding native Android M3 as it is anyway, for its 70%+ failure rate, at which point whether this test is enabled or not will be academic, since no one will be paying attention to the suite anyway.

Welcome to the sorry state of tests on Android... :-(

[Chris Jones [:cjones] inactive; ni?/f?/r? if you need me]

Joel, Ed, please disable these tests ifdef MOZ_WIDGET_ANDROID if they're only to be disabled for the fennec-android products.  We're trying to keep running and passing for b2g.

Comment 9

[Ed Morley [:emorley]]

Does B2G use testing/mochitest/android.json, I thought not?

Comment 10

[Chris Jones [:cjones] inactive; ni?/f?/r? if you need me]

I believe so, but that's a bug we're fixing.

Comment 11

[Ben Turner (not reading bugmail, use the needinfo flag!)]

Just to explain why this is a big deal: test_ipc.html is not a simple test but rather an entire OOP test suite. Disabling it means that we're entirely blind to breakage that could hose B2G. In fact, since the devicestorage test is also disabled, I'm not sure if we have *any* tests that run OOP on B2G now. Of course, if this test runs out of memory frequently and obscures other failures then we need to come up with something else, but we won't know unless it's re-enabled.

Comment 12

[Ed Morley [:emorley]]

I've backed out the test disabling; sorry for the misunderstanding as to platforms affected & for us thinking it was more closely related to bug 775053 than it actually was.

Thanks! Now I just hope it doesn't go orange frequently :)

Comment 16

[Ed Morley [:emorley]]

(Native Android mochitest-3 is hidden at the moment due to high overall rate of failure, hence the lack of TBPLBot posts here)

Comment 18

[Geoff Brown [:gbrown]]

indexedDB/ipc/test_ipc.html continues to fail on Native Android M3:

https://tbpl.mozilla.org/php/getParsedLog.php?id=13964532&tree=Firefox&full=1
https://tbpl.mozilla.org/php/getParsedLog.php?id=14003427&tree=Mozilla-Inbound&full=1

In many other Native Android M3 runs, test_ipc does not run at all, because of failures in dom/imptests (which I hope to disable soon).
