How to revert multiple commits as part of a single commit
This is not a major problem, just something I want to know whether or not is possible.
Let's say we have two commits, abcd123 and wxyz789, that occur at non-adjacent, separate places, far back in a repo's history. Now let's say we want to revert them. Doing
git revert abcd123 wxyz789
would result in two separate commits, one reverting abcd123 and the other reverting wxyz789.
This is all fine and well, but what if the mistakes we want to fix in the two commits are logically linked, and for the purposes of self-documentation we'd like to make one single commit containing one single "I broke something so now I'm reverting files x, y and z" comment? Is there a git command that does this?
(I am of course aware that it is possible to create a commit where I just manually fix all the changes and then push. This is painful for all the obbious reasons.)
Answer
You can do:
git revert abcd123
git revert --no-commit wxyz789
git commit --amend
... and then write an appropriate commit message describing the combined effect of reverting both commits.
