So far I have: * bzr log needs to be much faster for single files[1] and for subsets of history. * bzr diff -r needs to take at most a couple of seconds * bzr st needs to be instantaneous. * Must be able to get the diff between the current branch and its parent very quickly. These are all performance related. I can't recall coming across any other blockers, but then I haven't been following every email on this & related threads. If I've missed anything, please let me know. If I've included anything that's not really necessary, let me know. If you want, file bugs on https://bugs.launchpad.net/bzr/+bugs and give them the tag 'emacs'. jml [1] Bazaar tends to assume you want to work with the whole tree for every operation. I think this might be the root cause of a lot of the disappointment in Bazaar's performance.
