Currently the directories in ext/ and lib/ run in parallel but the test in each dir run in sequence. (Thanks to Nicholas of course) At the moment some tests in ext/ and lib/ are not parallel-safe, but some are... What would be a good way to mark the parallel-safe ones? This also to allow chaning the tests one by one instead of all at once which might not be possible. (since it would be best to keep everything in sync with CPAN (IMHO)) What I've been thinking about: - a .parallel file in the directories that are parallel safe - adding the list of safe modules in t/harness - creating another file that holds the list - ... (Currently the list of tests to run ext/ and lib/ is based on the MANIFEST file) Any ideas? Kind regards, BramThread Next
