Ugh, thanks for letting me know, this was supposed to come from a merge from an immutable branch from the tip folks, but I did a rebase -i to fixup a typo in a commit message and that seems to have flattened the merge :| I'll redo the last 3 commits in pdx/for-next to re-add the merge and do a forced push.

I have attached the current version of my check scripts (I can't use git hooks since I want to do these checks when I fetch trees). They both take a range of commits (I usually pass "^origin/master ..." (only 2 dots if the branch is just fast forwarded).

I didn't find it after some searching. We should be catching errors like this before they hit next. First, there is no reason we can't catch them - unlike the integration failures only next can catch. Second, once they are in next, there is no "right" way to fix them.

After a short period, testing will move to for-next and fixes branches in preparation for pull-requests, just as before. Thanks, 1. We may eliminate the testing branch as it may not offer any value over for-next, but we'll work through at least one release cycle before doing so. -- Darren Hart VMware Open Source Technology Center
Re: linux-next: Signed-off-by missing for commit in the drivers-x86 tree
+Olof and Arnd, I am curious how you handle the situation below as a maintainer team. This problem arose from a new for-next test which triggers on the committer not having a SOB tag in the patch (which can happen when a shared branch is rebased to drop a patch). Do you have a branch that you both use for testing and automated testing which you occasionally need to drop patches from before moving them to a publication branch like "for-next" or "fixes"? I understand you tend to pull from sub-maintainers, so perhaps our contexts are fairly different. Andy and I have brainstormed various approaches to addressing this, and all of the cures appear worse than the disease from a scalability and/or chance of error perspective (outlined below). Linus has been clear he sees "rebase --signoff" to be the wrong thing to do for "publicized branches" (see my comment below on published vs. collaboration branches).

For the platform driver x86 subsystem, Andy I have defined our "testing" branch as mutable. It's the place where our CI pulls from, as well as the first place 0day pulls from, and where we stage things prior to going to the publication branches ("for-next" and then sometimes "fixes"). We find it valuable to let the robots have a chance to catch issues we may have missed before pushing patches to a publication branch, but to do that, we need the testing branch to be accessible to them. The usual case that would land us in the situation here is we discover a bug in a patch and revert it before going to a publication branch. Generally, this will involve one file (most patches here are isolated), which we drop via rebase, and the rest are entirely unaffected in terms of code, but as the tree changed under them, they get "re-committed". This seems like a reasonable way to handle a tree with more than one maintainer and take advantage of some automation. Andy and I do need a common tree to work from, and I prefer to sync with him as early in the process as possible, rather than have him and I work with two private testing branches and have to negotiate who takes which patches. It would slow us down and wouldn't improve quality in any measurable way. Even if we did this work in an access controlled repository, we would still have this problem. With more and more maintainer teams, I think we need to distinguish between "published" branches and "collaboration" branches. I suspect maintainer teams will expose this rebasing behavior, but I don't believe it is new or unique to us. To collaborate, we need a common branch, which a lone maintainer doesn't need, and the committer/sign-off delta makes this discoverable, whereas it was invisible with a lone maintainer. Note: A guiding principle behind our process is that of not introducing bugs into mainline. Rather than reverting bad patches in testing, we drop them, and replace them with a fixed version. The idea being we don't want to introduce git bisect breakage, and we don't want to open the window for stable/distro maintainers to pull a bad patch and forget the revert or the fixup. If we can correct it before it goes to Linus, we do. > So I would definitely suggest against the "git rebase --signoff" > model, even if git were to do the "right thing".

For the platform driver x86 subsystem, Andy I have defined our "testing" branch as mutable. It's the place where our CI pulls from, as well as the first place 0day pulls from, and where we stage things prior to going to the publication branches ("for-next" and then sometimes "fixes"). We find it valuable to let the robots have a chance to catch issues we may have missed before pushing patches to a publication branch, but to do that, we need the testing branch to be accessible to them. The usual case that would land us in the situation here is we discover a bug in a patch and revert it before going to a publication branch. Generally, this will involve one file (most patches here are isolated), which we drop via rebase, and the rest are entirely unaffected in terms of code, but as the tree changed under them, they get "re-committed". This seems like a reasonable way to handle a tree with more than one maintainer and take advantage of some automation. Andy and I do need a common tree to work from, and I prefer to sync with him as early in the process as possible, rather than have him and I work with two private testing branches and have to negotiate who takes which patches. It would slow us down and wouldn't improve quality in any measurable way. Even if we did this work in an access controlled repository, we would still have this problem. With more and more maintainer teams, I think we need to distinguish between "published" branches and "collaboration" branches. I suspect maintainer teams will expose this rebasing behavior, but I don't believe it is new or unique to us. To collaborate, we need a common branch, which a lone maintainer doesn't need, and the committer/sign-off delta makes this discoverable, whereas it was invisible with a lone maintainer. Note: A guiding principle behind our process is that of not introducing bugs into mainline. Rather than reverting bad patches in testing, we drop them, and replace them with a fixed version. The idea being we don't want to introduce git bisect breakage, and we don't want to open the window for stable/distro maintainers to pull a bad patch and forget the revert or the fixup. If we can correct it before it goes to Linus, we do. > So I would definitely suggest against the "git rebase --signoff" > model, even if git were to do the "right thing".

In Darren's response it became clear that even though you had initially commited the patches, he had rebased them so he is now the committer.

Yeah, I agree. Rebasing really is pretty much the exact same thing as applying a patch. > "git rebase" does have a "--signoff" option. I think you end up signing off twice using that. I don't think it's smart enough to say "oh, you already did it once". But I didn't check. Sometimes git is a lot smarter than I remember it being, simply because I don't worry about it. Junio does a good job. And in general, you simply should never rebase commits that have already been publicized. And the fact that you didn't commit them in the first place definitely means that they've been public somewhere. So I would definitely suggest against the "git rebase --signoff" model, even if git were to do the "right thing". It's simply fundamentally the wrong thing to do. Either you already committed them (and hopefully signed off correctly the first time), or you didn't (and you shouldn't be rebasing). So in neither case is "git rebase --signoff" sensible. Linus

I would say that if you rebase someone's commit(s), then you are on the "patch's delivery path" and so should add a Signed-off-by tag. (cc'ing Linus to see if he has an opinion.

So each of these was originally committed by Andy... but appear as committed by me. This must have occured as a rebase of our testing branch I suppose. Nothing has been out of the ordinary this development cycle, so I wonder that we haven't received such a report previously. Hrm. Is this a new check Stephen?
