Lets suppose there is a central repository where commits from satellite ones are pushed some time. Developer A makes some commits on his repo while B makes some on his own too.
Now, A wants to incorporate one of B's commits into his repo (which he cannot access directly to pull).
One way is to have B create a patch and send it to A but in that case there are two problems: 1. The patch will appear as local modifications to A who have then to commit it (with its own name) 2. Once the central repo is updated the changes will conflict (being pushed by two different authors).
Is there a way to have the patch applied directly "as a commit" on local A repo so that it will appear to him as if it were pulled from the central repo (i.e. origin)?
PS: (this might not apply: see comments: is there a way to strike text until verified?) After some more investigation and testing looks like also git am < git-formatted-patch would make it so that the patch appears committed to the local master (then I hope it will be recognized as the same commit when B pushes it to the central repo). It looks like it is git apply that leaves the patch uncommitted...
回答1:
B could create and send a bundle rather than a patch. This allows sending commits when none of the transports available for push or fetch will work.
回答2:
git am is what you're looking for.
Ask him to commit locally and do git format-patch. This will create a patch. You can then use git am to add it to your repo.
