Description mitz 2007-04-17 03:40:03 PDT
run-webkit-tests hangs in http/tests/plugins/npapi-response-headers.html. Seen on the build slave many times (see URL) and locally on a G5.

You can reproduce this, Mitz?  Have you sampled it (Sharked it) yet during the hang?

It apparently started with this commit, although I'm not sure how this change would have caused that test to hang.

Yes, 'run-webkit-tests http/tests/plugins'.

It's just spinning in DRT's main runloop, presumably waiting for the notifyDone().

Sample of DumpRenderTree

Sample taken while DumpRenderTree was hanging.   There appears to be a lot of activity in CFNetwork.

That's bizarre!  There are 1001 invocations of dumpRenderTree() and 995 invocations of runTest()?!  Why would dumpRenderTree() be called that many times if the test was really "hung"?

What are the arguments to run-webkit-tests on the buildbot (or for this sample)?

I've disabled the test for now.
