Bug 94512 – OffscreenTabKeyboardEvents failing in chromium.webkit Linux Tests - browser_tests

• Status: RESOLVED
• Resolution: WONTFIX
• Component: Tools / Tests

Starting with http://build.chromium.org/p/chromium.webkit/builders/Linux%20Tests/builds/23265 , browser_tests has been failing in http://build.chromium.org/p/chromium.webkit/waterfall?show=Linux%20Tests 
(specific test that is consistently failing: OffscreenTabKeyboardEvents )

OffscreenTabsApiTest.OffscreenTabKeyboardEvents: 
[6:7:3564619352:ERROR:ipc_sync_channel.cc(378)] Canceling pending sends
[10:10:3564698129:ERROR:request_sender.cc(132)] Could not find specified request id: 1

Killed (timed out).

Here are the revisions in the blamelist:
webkit rev 126025-126030
chromium rev 152318-152324

Here are the changes that seem potentially related:
http://trac.webkit.org/changeset/126026 ([e-mail])
http://trac.webkit.org/changeset/126030 ([e-mail])

I don't see corresponding failures in https://chromium-build.appspot.com/p/chromium/console , so I suspect the culprit is indeed a webkit change.

Allan/Carlos- please take a look and see if you think your CL might be responsible.

I'm one of the webkit gardeners today (kbr is the other).  I have to take off soon; if this is not resolved by tomorrow morning, perhaps I will update my local Chrome tree (building against ToT webkit) and see if disabling one of the changes fixes the problem.

In the meanwhile, kbr says he will probably disable the test on the chromium side.

It's almost certainly not 126030 as that should only affect the WebKit2 port of WebKitGTK+.

[Kenneth Russell]

Note: http://trac.webkit.org/changeset/126026 was rolled out because it was causing assertion failures in one of the layout tests. It isn't yet known whether that will clear up the browser_tests failure; the most recent Linux Tests build, http://build.chromium.org/p/chromium.webkit/builders/Linux%20Tests/builds/23270 , hasn't caught up to the rollout yet.

Chromium-side issue: http://code.google.com/p/chromium/issues/detail?id=142993

[Kenneth Russell]

Note: I reproduced the OffscreenTabsApiTest.OffscreenTabKeyboardEvents timeout locally with a build including my rollout of http://trac.webkit.org/changeset/126026 , so that isn't it. Unfortunately, the offscreen tabs code is currently unmaintained, so I am going to disable the test for the time being.

[Carlos Garcia Campos]

My commit only affects the WebKit2 GTK+ API, so it's very unlikely it can break any layout test.

Update: The test stopped failing as of http://build.chromium.org/p/chromium.webkit/builders/Linux%20Tests/builds/23272

I don't know what caused it to stop failing...

[Kenneth Russell]

I disabled the test in http://src.chromium.org/viewvc/chrome?view=rev&revision=152493 , but the build you point to was before that one. Don't know why it was failing fairly consistently.

Marked LayoutTest bugs, bugs with Chromium IDs, and some others as WontFix. Test failure bugs still are trackable via TestExpectations or disabled unit tests.
