Hello Everyone, It seems given the decent amount of discussions it's time to make small announcement. So, official git mirrors are available for some subset of LLVM projects. They were used by some LLVM developers for couple of months already and seem to be stable enough. Right now there is a mirroring for LLVM itself and clang. More can be added per requests. The mirrors are made via running of git-svn on llvm.org inside post-commit hook, so they should be in theory as fresh as possible. Also, one can recreate git-svn metadata and enable such nice features like "git svn dcommit". The mirrors track only trunk mostly due to not so git'ish way of doing branches / tags in LLVM repository. The URLs for clone are: http://llvm.org/git/llvm.git http://llvm.org/git/clang.git It's not yet decided whether we'll run e.g. gitweb for mirrors, most probably - there won't be anything like this, viewvc should be enough for almost all purposes. PS: Patches to various sorts of documentation scattered here and there are welcome :) -- With best regards, Anton Korobeynikov Faculty of Mathematics and Mechanics, Saint Petersburg State University

Thanks Anton and everyone who worked on this! -Dave

This is how I use the Git mirror with git-svn: For the initial clone and setup: $ git clone http://llvm.org/git/llvm.git $ cd llvm $ git config --add remote.origin.fetch '+refs/remotes/git-svn:refs/remotes/git-svn' $ git fetch $ git svn init https://llvm.org/svn/llvm-project/llvm/trunk $ git svn rebase -l This will quickly build the git-svn metadata by using the magical remotes/git-svn branch fetched from the origin. To update I run: $ git fetch $ git svn rebase -l And to commit: $ git svn dcommit $ git fetch $ git svn rebase -l I have sometimes seen git-svn refusing to dcommit, claiming that I have uncommitted files in my tree. I think this happens when I forget to resynchronize the metadata after committing. Anyway, the solution is to wipe away all of .git/svn and rebuild it with "git svn rebase -l" /jakob

I notice that .gitignore in the root has tools/clang. This makes it necessary to use '--force' if using 'git submodule'. I do not know if there are any drawbacks to this - if someone knows, it would be interesting to know what those drawbacks are. One alternative would be for individuals who clone into tools/clone without using submodules to instead add tools/clang explicitly to .git/info/exclude.

To rebuild, it would be enough to remove .git/svn/refs/remotes/git-svn/.rev_map.* My usual way to resync; $ git fetch llvm.org (is remote name) $ git update-ref refs/remotes/git-svn llvm.org/master $ git svn fetch Partial-rebuilding .git/svn/refs/remotes/git-svn/.rev_map.91177308-0d34-0410-b5e6-96231b3b80d8 ...

I've been using Jakob's commands below, but it has stopped working for me. This happened roughly around the time when Anton added the other branches, but I'm not sure if that was the cause or not. The symptom is that the "git svn rebase -l" command does nothing except say that the master branch is already up to date, and "git svn dcommit" complains that files are out of date. In both cases, "git svn rebase" (without "-l") solves the problem, but without using the GIT mirror, so it's slow. I've tried re-creating my git repos from scratch but that did not fix the problem. Any ideas?
