httprepo: quote the path part of the URL This should fix a 'hg clone "http://hg.example.org/path with spaces/"' The code tries to do the right thing when the user passes a path that's already escaped in part (e.g. "http://hg.example.org/path%20with spaces/"). If we're redirected, urllib2 will happily follow the URL it's given without escaping anything. I'm not sure what we would have to hook to work around that.

dirstate: fix rebuild; add a test If rebuild calls invalidate, it will just queue a (re)read of the dirstate file, while what we really want is to empty the current state.

hgweb: don't use os.path.join to build URL parts

hgwebdir: change os.sep in the name of repos to "/"

convert: svn: remove debugging message

convert: look up copies in getchanges instead of getcommit svn: defer path expansion until getchanges to reduce latency, as well as memory usage when converting incrementally.

convert: svn: pull up path to file expansion code into separate function. This is part of the process for deferring path expansion until getchanges. Copy detection also needs to be moved out of the commit object.

convert: svn: hoist up branch creation check

convert: svn: remove dead code

convert: svn: add helper function for optrevs
