hgweb: initialize permhooks at definition time This is simpler than creating it empty and then appending the default checkauthz hook 50 lines below.

revset: fix undefined name ParseError

branchcache: improve speed relative to the amount of heads Updating the branch cache is quadratic to the amount of heads in the repository. One consequence of this was that cloning a pathological repository with 10,000 heads (and nothing else) took hours of CPU time. This patch makes one of the inner loop much faster, by removing a changectx instantiation, and removes another entirely in cases where there are no candidate branch heads which descend from other branch heads.

drop {short,hex}(ctx.node()) calls in favor of ctx methods

mq: add '.' and '..' to list of forbidden patch names When an empty string is being passed to normname it would return '.' causing checkfile() to always return that a patch with that name exists.

subrepo: handle svn tracked/unknown directory collisions This happens more often than expected. Say you have an svn subrepository with python code. Python would have generated unknown .pyc files. Now, you rebase this setup on a revision where a directory containing python code does not exist. Subversion is first asked to remove this directory when updating, but will not because it contains untracked items. Then it will have to bring back the directory after the merge but will fail because it now collides with an untracked directory. Using --force is not very elegant and only works with svn >= 1.5 but the only alternative I can think of is to write our own purge command for subversion.
