comparison mercurial/localrepo.py @ 5966:11af38a592ae

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Register data filters in a localrepo instead of util - Changing data filters implementation is easier, adddatafilter() can rewrap filter after inspecting their prototype - Custom data filters really belongs to localrepo, mixing them with generic wrapper like "pipefilter" or "tempfilter" looks wrong. - util.filtertable should not be accessed from extensions
