comparison tests/test-pathencode.py @ 18094:8ceabb34f1cb

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
test-pathencode: compare current pathencoding implementations We already have two implementations of the pathencoding (C and Python) and this test can perfectly well be used to probabilistically test them instead of just wasting CPU cycles and test time.
