annotate roundup/test/memorydb.py @ 6361:58817c3bf471

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Fix roundup/test Move the test-detectors in tx_Source_detector.py to roundup/test for two reasons: It's used in the memorydb convenience functions and it may be useful in other tests. Make the prefix a paramter of the convenience functions to be usable in other tests.
