I was doing this after working on gitweb a bit. In order to test gitweb, I need some local adaptations. I commited these to one branch and put all improvements to another branch. Then I merged both branches to one production path which is then used by the webserver. > While I think that is _one_ valid workflow, I am not convinced > that is _the_ best workflow. Me neigther.

He suggested to create a new branch (based on current HEAD) for the new commit.

Of course you can do this also while you are still on the test branch. While looking at code I often see unrelated stuff which can be cleaned up. With something like commit --branch it would be possible to stuff these changes to a "trivial" branch without having to change branches explicitly. > Johannes's workflow feels more natural > to me from this aspect -- I take the fix I discovered while > on the testing branch to the relevant topic to fix it.

I do not necessarily want that > extra merge immediately in the test branch. But if your commit to the topic is really different to previous commit on the test branch then you may have merge problems later. If you merge immediately, you even get the merged tree for free ;-). The testing branch is more like a throwaway-branch for me. I can recreate it anytime if I want and I don't care about extra merge commits here. > - A topic branch should be testable alone; That would be best, yes. Unfortunately it didn't work for me. Well I guess I could have put more effort on changing gitweb to be more general so that I don't need local adaptations. But I guess there are situations where this is not possible, too. Of course, now we have to answer the question whether GIT should support these situations. I don't know. -- Martin Waitz
