annotate tests/test_data_iterators.py @ 147:ab6e7e0e9d44

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Pass date information to routing when building URLs. This is so that URLs with dates in them can be built even when the date information is not coming from the source metadata, but from the page's config.
