Re: [platform-releng-dev] Stacktrace for DNFs in consolelog

[David M Williams <david_williams@xxxxxxxxxx>]

Hey Markus, do you have any code/scripts/techniques/pointers that others could use to "get stackdumps shortly before a plug-in test VM gets killed in automated tests". This is something I've always wanted to do in WTP, but never had the time ... so, if you have any time-saving tips, that'd be great! I'm sure for many.

Thanks,

As a side effect of the efforts to track down https://bugs.eclipse.org/342053 , you now get stackdumps shortly before a plug-in test VM gets killed in automated tests. 

E.g. for the failing org.eclipse.debug.tests_win32.win32.x86_6.0 in the N-build, the Console Output Log 
http://download.eclipse.org/eclipse/downloads/drops/N20110419-2000/testresults/consolelogs/win32-6.0_consolelog.txt 
now contains: 

     [echo] Running org.eclipse.debug.tests.AutomatedSuite. Result file: C:\buildtest\N20110419-2000\eclipse-testing/results/win32.win32.x86_6.0/org.eclipse.debug.tests.AutomatedSuite.xml.

While this doesn't explain why the tests hung up, it at least gives a hint at where to start investigating, and it lists the Focus Control (together with its ancestors) and the open Shells. The whole dump is repeated 2 seconds later. Since the code that prints the SWT infos uses "display.syncExec(..)", this may or may not influence a hung main thread. 

Note that the org.eclipse.test plug-in has not been tagged yet with this change, that's why you only see this in the N-build.

BTW: The jdt.ui.tests failures have been fixed in HEAD.
