annotate: abort early if no file is specified This change is intended to move the getdate function near the opmap table.

purge: avoid full walks when directories aren't purged If match.traversedir is not None, we're forced to do full walks. However when we aren't purging directories we don't need to set match.traversedir to anything. This speeds up non-full walks such as the one hgwatchman makes possible. For mozilla-central with hgwatchman enabled, 'hg purge --files' goes from 0.88 seconds to 0.22.

clone: for local clones, copy over filtered branchcaches as well (issue4286) Local clones copy/hardlink over files directly, so the branchcaches should all be valid. There's a slight chance that a read operation would update one of the branchcaches, but we hold a lock over the source repo so they shouldn't cause an invalid branchcache to be copied over, just a different, valid one.

clone: for local clones, copy branchcache from the right location (issue4286) The unfiltered branchcache is in .hg/cache/branch2, not .hg/store/cache/branch2.

obsolete: avoid 2-argument form of enumerate, which was new in Python 2.6

repoview: use util.sha1() instead of hashlib.sha1() 45b5cd948a4d accidentally broke Python 2.4 compatibility, this fixes it.

debugobsolete: display parents information from markers Now that we have a new field, we need a way to visualize it.

obsmarkers: add a `parentnodes` method to retrieve parent information

obsstore: also store the 'parents' field on disk We now store the `parents` field on disk. We use the same strategy as for `date`: We stick it into the metadata. This is slow and dirty, but this is also the only way we currently have. At some point we'll have a new obsstore format to store this properly.

obsstore: drop 'date' from the metadata dictionary We are extracting the `date` information from the metadata at read time. However, we failed to remove it from the metadata returned in the markers. This is now fixed.
