Advance warning of likley interruption of test results

Advance warning of likley interruption of test results

[Kris Van Hees]

In view of bugzilla tickets 5115, 5117, 5118, 5119 (and Mark's independently
filed ticket (5114), it is likely that no test results will be available for
builds starting today until sometime Monday.  The bugs relate to test  cases
that causes hangs, and the automated build-and-test system will run in  full
unattended mode for the Columbus Day holiday weekend.

Unfortunately, testsuite hangs are a problem that cannot be  handled  in  an
automated fashion (other than killing the testsuite which  will  give  bogus
results).

Cheers,
Kris

Part of these are because the kernel version strings are all over the
place with newer fedora kernels which means we don't properly detect
when utrace is installed and unresolvedOnUtrace() doesn't trigger. The
only constant seems to be that it ends with .fc<release>[xen|debug] so I
changed the fedora release matcher to look for that (we loose the major
and minor number of the distro version, but we weren't using that
anyway). That resolves 2 of them, the other two I added to
unresolvedOnUtrace(5144) and added more info to the bug tracker about
the kernel versions when this occurs (full investigation needed, but I
don't have time for that right now).

frysk-sys/frysk/junit/ChangeLog
2007-10-05  Mark Wielaard  <mwielaard@redhat.com>

    * KernelVersion.java (fedoraMajor, fedoraMinor): Removed.
    (KernelVersion): Adjust fedoraPattern to only check for fc ending.
    (newer): Don't check fedoraMajor or fedoraMinor.

frysk-core/frysk/proc/ChangeLog
2007-10-05  Mark Wielaard  <mwielaard@redhat.com>

    * TestProcStopped.java (testStoppedAckDaemon): Mark
    unresolvedOnUtrace(5114).
    (testStoppedDetached): Likewise.

Tested on 2.6.22.7-57.fc6 (x86_64) and 2.6.23-0.217.rc9.git1.fc8 (x86).

Cheers,

Mark
