shrink-revlog: add "reverse postorder" and "postorder reverse" toposorts. Based on a patch by Benoit Boissinot, adapted to the pluggable sort algorithm design. toposort_reversepostorder() is a very good performer; it's designed to recreate what the revlog would have looked like if Mercurial had parent deltas now. toposort_postorderreverse() is unstable and very inconsistent, but perhaps with some work it could be made better.

shrink-revlog: add --sort option for user-selectable toposort algorithm.

shrink-revlog: rename some local variables for consistency.

shrink-revlog: instrument sort code to record statistics. Notably, count "suboptimal" nodes (predecessor is not first parent) and (with -v) report them at the end of the run.

convert: handle svn tree with empty roots (issue2079)

bundle: fix bundle generation for empty changegroup

patch/diff: move diff related code next to each other

remove header handling out of mdiff.bunidiff, rename it

remove contrib/hgdiff, it makes refactoring diff/patch harder it can always be revived if needed

demandimport: blacklist _ssl (issue1964)

patch/diff: move patch.export() to cmdutil.export() This API change will allow us to break a cycle between patch and cmdutil.

wix: pre-check the 'I approve this license' checkbox This is simply a convenience to the user, they can click next until the installer goes away. Optimally, the checkbox would be hidden or removed, but that requires rewriting the UI.

addremove: avoid fetching data again and again

addremove: add progress support for similarity search

addremove: atomically update the dirstate In case someone hits ^C during the similarity search, properly rollback

inotify: expose the same dirstate.status() interface as dirstate. The real dirstate.status() does not have any keyword args. For consistency, wrappers or subclasses should not have them either.

keyword: remove spurious locks, improve handling of wlock - kwcommitctx is inside the wlock of repo.commit: no lock - _kwfwrite only needs wlock wlock outside try block, so we don't need to import lock.release _kwfwrite should even be safer that way, as we moved the status call inside the try-except block. Thanks to Benoit Boissinot for help.

keyword: use status' names instead of index

hgweb/graph: edge should be same color as the destination

templatefilters: store the agescales in reverseorder directly

hgweb: separate generation of entries and sorting (cleanup)

Merge stable

demandimport: add __main__ to the blacklist (because of setuptools)

bookmarks: add invalidate() to bookmark_repo Cached bookmark information would not be reset when repo.invalidate() was called, meaning (for instanced) guis would be left with out-of-date bookmark info. This patch fixes that by overriding bookmark_repo.invalidate()

branch: help misuse of hg branch to switch branches Maybe beginners tend to use 'hg branch EXISTING_BRANCH' instead of 'hg update EXISTING_BRANCH' as me. If so, let's help them to use 'update'. Also removed '(use --force to override)' because it can mislead them.
