Git - generate patch for all commits in a branch

问题

How can I generate patch for all commits in a given branch by knowing only the branch name?

This step is part of a complex workflow all of which is being automated. Hence requiring someone to manually determine the first commit in the branch is not an option.

Note that anything relying on reflog is not an option either because changes in the branch are not made locally.

回答1:

If you know from which branch your "given branch" has been created, then making a patch is easy:

git diff master Branch1 > ../patchfile
git checkout Branch2    
git apply ../patchfile

(and you can generate a patch applicable without git too)

But finding the right "creation commit" of a branch can be complex: see "Finding a branch point with Git?"

The OP akirekadu used:

git format-patch $(git merge-base --fork-point master)..branchB 

You can see it used in "git diff between working copy and branch base"
