dirstate.invalidate: avoid rebuilding _map Since hasattr will call __getattr__, the call to hasattr(self, '_dirs') will end up reparsing the dirstate file.

add dirstate._dirtypl variable Theoretically, it's possible to forget modified dirstate parents by doing: dirstate.invalidate() dirstate.setparents(p1, p2) dirstate._map The final access to _map should call _read(), which will unconditionally overwrite dirstate._pl. This doesn't actually happen right now because invalidate accidentally ends up rebuilding dirstate._map.

archive: delay extraction of file revisions This allows us to look only at the filelogs we're interested in, providing a nice speedup if we're archiving only part of a repository.

convert/subversion: work around memory leak in svn's python bindings The svn.ra.get_log wrapper attaches the hash of changed paths for every log entry to a global memory pool, so memory consumption increases rapidly, with no way to free it. Our workaround is to call this function in a child process, and feed its results back over a pipe. The memory consumption of the child still grows huge (hundreds of megabytes), but at least it goes away once the reading-the-log phase is done.
