https://bugzilla.mozilla.org/show_bug.cgi?id=1459200 is one step in that direction. And git-cinnabar version 0.5.0b4 and newer support cloning from a git reference repo[1]. There is even a mercurial extension[2] to make this more automated, but git-cinnabar won't try to use it by default for now. I want to add support for git bundles, or at least future-proofing for git bundles, first. The reference repo would also need to be updated frequently. Mike 1. For example, you can do: git -c cinnabar.clone=https://github.com/glandium/gecko clone hg::https://hg.mozilla.org/mozilla-unified 2. https://github.com/glandium/git-cinnabar/blob/master/mercurial/cinnabarclone.py _______________________________________________ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform
