52873 2011-01-21 01:29:10 -0800 Chromium DRT should provide command-line option for specifying timeout to ease debugging 2011-02-15 22:48:23 -0800 1 1 1 Unclassified WebKit Tools / Tests 528+ (Nightly build) All All RESOLVED FIXED P2 Normal --- 0 wangxianzhu webkit-unassigned commit-queue dglazkov eric phnixwxz tkent tony oldest_to_newest 337933 0 wangxianzhu 2011-01-21 01:29:10 -0800 When debugging DRT, we need to specify a larger timeout so that DRT won't timeout during debugging. Though we can specify timeout in test-shell mode, sometimes the non-test-shell mode is more convenient to use in debugging. 338011 1 79724 wangxianzhu 2011-01-21 04:50:38 -0800 Created attachment 79724 patch 339303 2 eric 2011-01-24 15:29:46 -0800 We're tryign to be more like the other DRTs, not less. :) How do other DRT implementations handle this case? 339612 3 wangxianzhu 2011-01-25 05:47:43 -0800 (In reply to comment #2) > We're tryign to be more like the other DRTs, not less. :) How do other DRT implementations handle this case? Other implementations seem to also have the timeout issue. I just asked a colleague how he prevent timeout when debugging DRT, he answered he just modifies DRT to disable timeout. Wondering how others do. If you think the feature is useful, I'd be glad to add it into other ports. 339699 4 79724 tony 2011-01-25 09:45:30 -0800 Comment on attachment 79724 patch I think it's OK to add this, however I think it would be better if it were just a flag like --disable-time-out. I don't see the benefit in being able to specify a timeout. 340027 5 phnixwxz 2011-01-25 17:01:57 -0800 (In reply to comment #4) > (From update of attachment 79724 [details]) > I think it's OK to add this, however I think it would be better if it were just a flag like --disable-time-out. I don't see the benefit in being able to specify a timeout. For --disable-time-out, the implementation will be 'shell.setLayoutTestTimeout(INT_MAX)' instead of changing all of the TestShellXXX.cpp to actually disable timeout. Would this look good to you? 340029 6 tony 2011-01-25 17:11:24 -0800 (In reply to comment #5) > For --disable-time-out, the implementation will be 'shell.setLayoutTestTimeout(INT_MAX)' instead of changing all of the TestShellXXX.cpp to actually disable timeout.

Yes, I think that's ok. 340149 7 80169 wangxianzhu 2011-01-25 22:07:53 -0800 Created attachment 80169 Updated patch: --no-timeout I just investigated non-Chromium DRTs and found that they are different from Chromium DRTs about timeout. Chromium DRTs will call 'exit()' on timeout, while non-Chromium DRTs call notifyDone() which will cause exiting in the next message loop. So for the latter timeout is not a big issue for debugging. 340337 8 80169 tony 2011-01-26 10:30:25 -0800 Comment on attachment 80169 Updated patch: --no-timeout View in context: https://bugs.webkit.org/attachment.cgi?id=80169&action=review At some point, we should see if we can get Chromium DRT to do the same as Mac DRT and call notifyDone on timeout. > Tools/DumpRenderTree/chromium/DumpRenderTree.cpp:191 > + // 0x20000000ms is big enough for the purpose to avoid timeout in debugging. > + shell.setLayoutTestTimeout(0x20000000); Why did you decide against INT_MAX from climits? 340370 9 80169 commit-queue 2011-01-26 11:54:10 -0800 Comment on attachment 80169 Updated patch: --no-timeout Clearing flags on attachment: 80169 Committed r76704: <http://trac.webkit.org/changeset/76704> 340371 10 commit-queue 2011-01-26 11:54:14 -0800 All reviewed patches have been landed.

Sometimes NRWT must kill the DRT process if it wants a timeout shorter than 30s. For Chromium DRT, the script can specify timeout for each test in test-shell mode. 2. If the DRT process is busy in a loop, it can't quit by itself and can only be killed. > > Tools/DumpRenderTree/chromium/DumpRenderTree.cpp:191 > > + // 0x20000000ms is big enough for the purpose to avoid timeout in debugging. > > + shell.setLayoutTestTimeout(0x20000000); > > Why did you decide against INT_MAX from climits? I'm afraid if INT_MAX as a timeout was added to some value it would overflow, for example, some port might need 1 more second for timeout. 351877 13 wangxianzhu 2011-02-15 21:46:55 -0800 Sorry there is a small bug in the last patch. 351879 14 82588 wangxianzhu 2011-02-15 21:47:52 -0800 Created attachment 82588 Fix a small bug 351880 15 82588 tkent 2011-02-15 21:54:49 -0800 Comment on attachment 82588 Fix a small bug ok 351892 16 82588 commit-queue 2011-02-15 22:48:17 -0800 Comment on attachment 82588 Fix a small bug Clearing flags on attachment: 82588 Committed r78685: <http://trac.webkit.org/changeset/78685> 351893 17 commit-queue 2011-02-15 22:48:23 -0800 All reviewed patches have been landed.
