Description Carlos Alberto Lopez Perez 2014-05-14 14:37:16 PDT
On platform GTK the Layout Test http/tests/security/cross-origin-plugin-private-browsing-toggled.html is failing.

This test was removed from the expectations on http://trac.webkit.org/changeset/159744

However is failing again now.

Investigating the specific revision that made it start failing again is pending.

> Investigating the specific revision that made it start failing again is pending.

This is the summary of my investigation for this test on the GTK port (release build).

The following timeline was obtained with the help of https://github.com/clopez/webkit-testhunter

http://trac.webkit.org/changeset/156532 <-- Test stop failing on GTK (msanchez)
http://trac.webkit.org/changeset/159744 <-- Test get removed from GTK TestExpectations (msanchez)
http://trac.webkit.org/changeset/168668 <-- Test starts failing again on GTK (jhoneycutt)

Before r168668 the test only works if you run many tests in parallel (Fails otherwise)

For example:

Try to build r168667 and test to run all the http/* tests in parallel with:

Tools/Scripts/run-webkit-tests --no-show-results --no-new-test-results --no-sample-on-timeout --results-directory layout-test-results --debug-rwt-logging --release --webkit-test-runner --gtk --retry-failures http

You will see that http/tests/security/cross-origin-plugin-private-browsing-toggled.html passes.

Now, on r168667 run only the test http/tests/security/cross-origin-plugin-private-browsing-toggled.html alone:

Tools/Scripts/run-webkit-tests --no-show-results --no-new-test-results --no-sample-on-timeout --results-directory layout-test-results --debug-rwt-logging --release --webkit-test-runner --gtk --retry-failures http/tests/security/cross-origin-plugin-private-browsing-toggled.html

It will fail!.

Now, if you build r168668, and try the tests again, you will see that this test fails always. No matter if you run the test alone or in parallel with the other tests.

This drove me crazy because I was not able to reproduce the behaviour reported by the bot, until I tried to run all the test suite (like the bot does) instead of only running this test alone.


-> Before r168668: The test fails if you run it alone, but works if you run it in parallel with the other tests.

-> On r168668: The test fails always.

So maybe there is some race condition here?

I have updated the TestExpectations file for GTK for this test on r168865 <http://trac.webkit.org/r168865>


And I have just noticed that r168668 got reverted on 168843 <http://trac.webkit.org/168843>

Plugins are no longer supported.
