What would be the consequences of reverting the original commit while the same had been cherry-picked to the target branch?
There is a branch (say feature) with some changes (commit: A), while this change was expected to be in another branch (say integration).
So, I cherry-picked this change (commit: A) from feature branch to integration branch (resulting into a new commit: AC, in integration branch).
However, due to testing needs, the feature branch is not expected to contain this change (commit: A) at all.
Hence, I had to revert A from the feature branch (resulting in a revert commit AR, in the feature branch).
Now, if later I merge this feature branch into the integration branch, would there be any issues or conflicts in the changes that had been cherry-picked initially.
[After this merge, integration will have all the 3 commits, viz. A, AR, AC]
The commit AR will nullify the commit A, won't it nullify the commit AC too?
No, it should be fine. AR will only revert A's changes then AC will reinstall them.
Also to note : you could have considered resetting to the commit just before A (git reset --hard A^) instead of reverting it, but I guess it's heavily depending on the specifics of your situation, and maybe a bit on workflow style choices.
