It is nice that we can achieve a large part of this feature with existing infrastructure. It would be nice if we ship such pre-rebase hook with git, so people can just enable it if they want to use this functionality, like the default pre-commit hook that checks for whitespace errors. > Unfortunately, the pre-rebase hook only affects 'git rebase', and in > order to do the same check on 'git commit --amend' you'd have to write > a similar pre-commit hook (don't know how easy it is to find the > amended commit from within the hook). Maybe we should add a > pre-rewrite hook that trigger in the same situations as the > post-rewrite hook. pre-rewrite hook would be a really nice to have, especially that it would (I hope) cover third party tools like various GUIs for git; and also git-filter-branch. Note however that the safety net, i.e. refusing or warning against attempted rewrite of published history is only part of issue. Another important part is querying and showing "phase" of a commit. What I'd like to see is ability to show among others in "git log" and "git show" output if commit was already published or not (and if it is marked 'secret'). > This should take care of the simplest 'public' use case in a > push-based workflow.

Well, addition of pre-push / pre-publish was resisted on the grounds that all it does is something that can be as easy done by hand before push. Perhaps this new use case would help bring it forward, don't you think?
