Thanks for the hint, this was indeed the solution. And there is actually no need to patch the source because, considering the way git-filter-branch.sh is written, the user-specified parameters come after the hard-coded --topo-order and it seems that --date-order overrides it if it comes after it. So I just had to use git filter-branch --msg-filter svnmsg2git --tag-name-filter cat -- --date-order --all instead of my original command. The only remaining question I have is why isn't --date-order the default? At least when using message filter, it seems to me that we always want to rewrite commits in chronological order to deal with possible back references (even when not migrating from svn, commit messages can still refer to previous commits, like e.g. the ones created by "git revert" do and they need to be updated when rewriting history). So why not use it in git-filter-branch.sh? BTW, the explanation for the new errors I was getting with --date-order was that I had some artificial commits generated by cvs2svn in the history of this repository which had _exactly_ the same date as the previous commit and --date-order sorted them in the wrong order for some reason. I got round this by simply checking for the specific form of the message (which is "This commit was generated by cvs2svn to compensate for changes in rNNNNN, which included commits to RCS files with non-trunk default branches.") and replacing "rNNNNN" with "the previous commit" in this particular case in order to avoid the problem. Thanks again for your help!
