Comment 1

[Cosmin Sabou [:CosminS]]

This is perma-failing since this push landed https://treeherder.mozilla.org/#/jobs?repo=mozilla-inbound&filter-searchStr=9fcf78c3a312455760c74d8e9f133a3bad6997e4&fromchange=7fd86a767e08d8eb773bdce22766ded22d02692c&tochange=d3442210b7b8a8f60f1b89b27dcf925e560ecbe7&selectedJob=179300474&filter-resultStatus=success&filter-resultStatus=testfailed&filter-resultStatus=busted&filter-resultStatus=exception&filter-resultStatus=running&filter-resultStatus=pending&filter-resultStatus=runnable

Boris, could you please take a look at this? Thank you.

Comment 2

[Boris Zbarsky [:bzbarsky]]

So the real issue here is this bit, right?

[task 2018-05-19T04:40:23.233Z] 04:40:23     INFO - PID 6095 | Assertion failure: GetReadyStateEnum() == nsIDocument::READYSTATE_LOADING (Bad readyState), at /builds/worker/workspace/build/src/dom/html/MediaDocument.cpp:197

The image bridge asserts are presumably just because that process is dead, killed by this fatal assert.  This has nothing to do with graphics.

This is only failing on the tier2 webrender jobs?  :(

Presumably fallout from bug 894215, though why it would be webrender-specific is not clear to me.

Comment 4

[Boris Zbarsky [:bzbarsky]]

I guess I should have been clearer that comment 2 is a question about where this is observed to be failing and hence how I should go about trying to reproduce it...

Comment 5

[Sebastian Hengst [:aryx] (needinfo me if it's about an intermittent or backout)]

All failures except one are on Linux x64 QR - the other one is on OS X.

The failure
a) is intermittent
b) always occurs in /html/dom/dynamic-markup-insertion/document-write/contentType.window.html
c) can be observed before bug 894215 landed - first fail is https://treeherder.mozilla.org/#/jobs?repo=mozilla-inbound&revision=6c8bf287d25b8d1ebc0392812b9328d57744233c&filter-searchStr=9fcf78c3a312455760c74d8e9f133a3bad6997e4&filter-resultStatus=success&filter-resultStatus=testfailed&filter-resultStatus=busted&filter-resultStatus=exception&filter-resultStatus=running&filter-resultStatus=pending&filter-resultStatus=runnable

The test got added in bug 1449529. Anne, please take a look at this.

Comment 6

[Boris Zbarsky [:bzbarsky]]

> can be observed before bug 894215 landed

OK, good.  At the same frequency, or do we not know?

Anne isn't going to tell you anything useful here; he just wrote a test that does things you can expect a webpage to do.  The real issue is in the document/navigation code.

Anyway, this looks like a duplicate of bug 1462789, most likely.  And that bug has an rr capture in bug 1462789 comment 4!  I'll take a look at that soonish.

Comment 7

[Boris Zbarsky [:bzbarsky]]

Oh, and the point is bug 1462789 tracks the "GetReadyStateEnum() == nsIDocument::READYSTATE_LOADING" assert failure.  This bug is tracking the image bridge thing, but that's very likely to be a webrender-specific assert that just ends up firing any time the content process dies.  And it's dying because of the readystate assert.  So I expect fixing bug 1462789 will fix this specific manifestation of the image bridge assert, but there can in general be lots of causes of the image bridge thing: anything that kills the content process.

Comment 8

[Sebastian Hengst [:aryx] (needinfo me if it's about an intermittent or backout)]

Failure rate looks similar.

Comment 10

[Kartikaya Gupta (email:[e-mail])]

Moving this bug to WebRender component so that we robustify the WebRender code against a content process dying. We can use bug 1462789 to track the specific content process crash that's the root cause of this intermittent failure.

Comment 13

[Sebastian Hengst [:aryx] (needinfo me if it's about an intermittent or backout)]

There are several reports with this assertion spam and a (random?) test failing (e.g. bug 1522767, bug 1522769).

Jeff, can you check what has changed, please?

Comment 14

[Jeff Muizelaar [:jrmuizel]]

No idea what would cause this. Sotaro, do you have any idea?

Comment 15

[Sotaro Ikeda [:sotaro]]

I also do not have idea what cause this :(

default m-c caused a lot of intermittent failures on both Linux x64 QuantumRender debug and Linux x64 QuantumRender opt.
https://treeherder.mozilla.org/#/jobs?repo=try&revision=c9c42930de4e5663f0e2395bde9e331dd7c9a92c

In Linux x64 QuantumRender opt failures, there were "INFO - IOError on command, setting status to CRASH" message just before TEST-UNEXPECTED-CRASH.

https://treeherder.mozilla.org/#/jobs?repo=try&revision=c9c42930de4e5663f0e2395bde9e331dd7c9a92c

I added the log and tried tests. Same failure happened on both Linux x64 QuantumRender debug and Linux x64 QuantumRender opt. And
ImageBridgeParent::GetInstance() was called for already destroyed ImageBridgeParent.

Comment 17

[Sotaro Ikeda [:sotaro]]

By try tests log, ImageBridgeParent::GetInstance() was called from ImageBridgeParent::NotifyImageComposites(). The NotifyImageComposites() seems to have a problem when ImageBridgeParent::GetInstance() fails.

Yes

Has the fix been verified in Nightly?

Yes

Needs manual test from QE?

No

If yes, steps to reproduce

List of other uplifts needed

Avoids a hang, let's uplift for beta 5.
Should also be helpful for WebRender experiments in 66.

Comment 29

[Sotaro Ikeda [:sotaro]]

(In reply to Narcis Beleuzu [:NarcisB] from comment #27)

:sotaro , the fail reappeared on mozilla-beta as a Tier2 failure.
Could you please take a look?

The fix addresses the infinite loop in ImageBridgeParent::NotifyImageComposites(), but "Cannot find image bridge for process" could sometimes happen with WebRender because of its architecture. It seems better to change NS_ASSERTION to NS_WARNING.
