GIT CHERRY PICK A MERGE COMMIT FULL

An interactive rebase lets you drop commits, add commits, edit, reword, or fixup/squash commits. > Rebasing is constructing a set of operations. Otherwise, the new tree is simply a combination of the parents' trees. The tree of the merge commit may contain new blobs not present in any of the parents if conflict resolution was required. It is a completely normal commit, having multiple parents like any commit can. > A new commit containing merged content is created, as well as a merge commit with the second parent that documents that a merge happened and what was merged.Ī merge only produces one commit: The merge commit, pointing to the tree of the merged content. Good luck explaining an N-way merge with this approach, such as the 66-way 'cthulhu merge' that is 2cde51fbd0f3 in the linux tree.Īll parents are metadata, they do not contribute to the content of the commit other than their 'parent' line in the commit object after the merge finished.

The way a merge works is essentially to compute the commits you need to cherry-pick, then cherry-pick them without committing, resolving conflicts in pretty much the same way git cherry-pick does, THEN commit with two parents. I aver that it is easier to understand the above than to think of merging and rebasing and cherry-picking as fundamentally different operations. Squashing a commit is essentially doing `git cherry-pick -no-commit` of the to-be-squashed commit and then `git commit -amend` to replace the HEAD commit with a new commit that includes the changes staged by `git cherry-pick -no-commit`. construct a set of commits to pick as theĪnd the selected commit) and the selectedĪn interactive rebase lets you drop commits, add commits, edit, reword, or fixup/squash commits. Rebasing is constructing a set of operations: Rebases just run another git action for every commit in a sequence, e.g. > Squash is 'Remove all commits from C_newest to C_oldest, and create a new commit using C_newest tree'. Git merge does the same thing for automatic (and manual) conflict resolution as git cherry-pick. In this case, you have to make a new blob yourself (the 'resolution') for use in the merge commit's tree, instead of using one of the parent blobs. > A merge conflict is a case where both trees changed the same blob since their common ancestor.

GIT CHERRY PICK A MERGE COMMIT FULL

The full history of all activity is retained.Ī new commit containing merged content is created, as well as a merge commit with the second parent that documents that a merge happened and what was merged. > It does not modify any blobs, nor does it modify the parent commits. A merge is a commit with two parent commits, pointing to a new tree that contains the blobs from both parents.
