Comment 1 Stepan Kasal 2006-08-09 19:43:27 UTC
Oh, as of now, there are about 40 ``failures'' and about 10 ``errors''

A typical ``failure'' looks like this:

38)
testTerminatedKillHUP(frysk.proc.TestTaskTerminateObserver)junit.framework.AssertionFailedError:
event loop run explictly stopped (startChild (Sig_USR1))
   at frysk.proc.TestLib.assertRunUntilStop(TestRunner)

   at frysk.proc.TestTaskTerminateObserver.terminated(TestRunner)
   at frysk.proc.TestTaskTerminateObserver.testTerminatedKillHUP(TestRunner)
   at frysk.junit.Runner.<init>(TestRunner)

A typical ``error'' looks like this:

11)
testBlockingWhileTerminating(frysk.proc.TestTaskTerminateObserver)java.lang.NullPointerException
   at frysk.proc.TestTaskTerminateObserver.testBlockingWhileTerminating(TestRunner)
   at frysk.junit.Runner.<init>(TestRunner)

Comment 2 Stepan Kasal 2006-08-15 17:41:48 UTC
OK, so the mass break from comment #1 is fixed now.

The problems described in the original submission are still not solved on i386,
I'll mark them with brokenXXX(3005) in the CVS.
(The same tests pass on x86_64.)
Comment 3 Stepan Kasal 2006-08-18 18:56:03 UTC
No, they should not be marked by brokenXXX, because that would exclude them from
junit runs, too.
Comment 4 Mark Wielaard 2006-08-21 14:34:49 UTC
Could you add some more info about the environment and versions you are using?

./TestRunner frysk.proc.TestProcGet passes for me on both:
2.6.17-1.2174_FC5 x86_64 GNU/Linux
2.6.17-1.2573.fc6 i686 i386 GNU/Linux

./TestRunner frysk.proc.TestTaskSyscallObserver passes on:
2.6.17-1.2174_FC5 x86_64 GNU/Linux
But fails (1 in 3) when run on:
2.6.17-1.2573.fc6 i686 i386 GNU/Linux
1)

Comment 5 Stepan Kasal 2006-08-21 15:01:02 UTC
I'm runnig the tests as part of the build on a build server.
IIRC, they usually have RHEL4, which should mean RHEL 4U4 these days.
(Details in another comment later/below.)

So yes, if the problem can be blamed on an obsolete kernel, then the fix is to
switch this check off in the spec file.  But I'm not able to judge this.
Comment 6 Stepan Kasal 2006-08-21 15:43:22 UTC
The build system uses:
Linux 2.6.9-34.ELsmp #1 SMP Fri Feb 24 16:56:28 EST 2006 i686 i686 i386 GNU/Linux

If the problems can be blamed on this kernel, then the right solution is to
switch off the checks (at the build time only).
