I'm unable to download, arc patch fails with "Base commit is not in local repository"

I am able to download raw diff... ...did I upload something wrong?

I can download the raw diff as well, but that one is lacking the commit message and the authorship. This I cannot push it.

Did you upload a patch or a git patch?

arc patch works fine for me. "Base commit is not in local repository" is just informational BTW, you also get this if it will work.

Are you sure you are in the correct repository, i.e. kwin? (Sorry for the dumb question ;)

For me it doesn't. It then tries to connect to github and asks for my github username and password. Which I don't have.

Sorry for intruding here Martin, but smoothing this out and understanding where we still have problems is important for T7116: Streamlined onboarding of new contributors ;)

Hovering over the timestamp, it says "Via Web". Until T5242 is solved, Phabricator will not take over any authorship information from patches uploaded via the web uploader. You can do one of two things now:

• Ask the author to use Arcanist.
• Ask the author to provide name and email, then issue git commit --amend --no-edit --author "name <name@domain>".

This can be debugged further with arc --trace patch. My working theory is that your working directory is not a checkout of origin/master, but instead a branch with the upstream tracking branch set to GitHub perhaps (or some .gitconfig issues?). Note that arc patch basically does a git fetch.

If Arcanist is not used to upload the patch, arc patch won't be able to attach the patch to the original base commit, it will always use HEAD of the current branch.

Further option to try: --skip-dependencies

All right, let's track that down.

I now removed the github remotes and afterwards it worked.

@nerdopolist As you've been around for a while, please make the effort to set up Arcanist. Then do arc patch D9567 and re-upload with arc diff. Otherwise Martin does not have your contact information for landing the patch.

@graesslin Thanks for debugging…

Seems like --all of git fetch is the reason. Thinking about it, that's probably wanted behaviour, because in general the review workflow allows the author to choose arbitrary branches to base his work on, so Arcanist has to fetch all of them.

More specifically, the root cause is that Roman deleted his kwin fork from GitHub, so trying to access that fails, and git falls back to asking for credentials. If I change subdiff to kde (which is accessible), it works. I wonder why you never ran into this with arc patch before, as this is not really specific to this patch, but any invocation of arc patch should trigger it.

Conclusion: Our current strategy of pushing new contributors to use Arcanist is likely still the way to go. Your issue is something to be aware of, but I'm hesitant to clutter the docs with this very special case (will reconsider if this comes up more often, of course).

Happy hacking.

I have an explanation for that: I have two systems I use for hacking and maybe the other one doesn't have that remote and by pure chance I always used that one.

I'll see what I can try with Arcanist... ...but I could not figure out how to do the patch series with it...

OH NO!

Let me know if I did this correctly. I might need help with the other ones.

From an Arcanist point of view, you did fine ;) However, the format of the author field in Git should normally be "Firstname Lastname <mail@domain>", please correct that.

Also, you could rebase your patch on latest master:

git checkout arcpatch-D9567
git fetch
git rebase origin/master
# Check if it still compiles
arc diff

For your other Diffs, I'll add instructions in a minute. After you followed them, Martin should be able to land all of those patches on your behalf.

Done, and sorry for all the notifications. Those dependent revisions are sometimes tricky, but with Arcanist there should be no problem now anymore. If you are quick, this will hopefully be reviewed and landed shortly, to avoid having to rebase again…

Good luck ;)

Is there something I need to run before

git checkout arcpatch-D9567

arcpatch-D9567 is unknown to git

Looking at Diff Detail → Branch, your local checkout is apparently called arcpatch-D9567_1.
