--- Comment #5 from Worker Ant <bugzilla-bot at gluster.org> ---
COMMIT: https://review.gluster.org/20740 committed in master by "Atin
Mukherjee" <amukherj at redhat.com> with a commit message- tests: Preserve tarball
of tests when they timeout

When tests timeout, the timeout command sends TERM
signal to the command being executed. In the case of run-tests.sh
it invokes prove, which further invokes perl and finally the test
is run using bash. The TERM signal does not seem to be reachnig
the end bash that is actually executing the tests, and hence
when any test is terminated due to a timeout, the cleanup routine
in include.rc does not get a chance to run and preserve the
tarball.

Further, cleanup invokes tarball generation, but is invoked at
the beginning and end of every test, and at times in beteween
as well. This caused way too many tarballs in case we decide to
preserve the same whenever generated by cleanup.

This patch hence moves the tarball generation to run-tests.sh
instead, and further stores them named <test>-iteration-<n>.tar
and also prints tarball name generated and stored per iteration.

This should help relate failed runs to the tarball iteration #
and to look at relevant logs.

Further the patch also provides a -p option to run-tests.sh for
unit testing purposes, where running a test in a loop without the
option will generate as many tarballs, and using the option will
reduce this to preserving the last tarball, saving space in
smaller unit test setups.
