Let’s imagine that we have a master branch.
Then we create a newbranch
git checkout -b newbranch
and make two new commits to newbranch: commit1 and commit2
Then we switch to master and make cherry-pick
git checkout master
git cherry-pick hash_of_commit1
Looking into gitk we see that commit1 and its cherry-picked version have different hashes, so technically they are two different commits.
Finally we merge newbranch into master:
git merge newbranch
and see that these two commits with different hashes were merged without problems although they imply that the same changes should be applied twice, so one of them should fail.
Does git really do a smart analysis of commit’s content while merging and decide that changes shouldn’t be applied twice or these commits are marked internally as linked together?
