The merge method

The method does a merge over the current working copy. It gets an Oid object as a parameter.

As its name says, it only does the merge, does not commit nor update the branch reference in the case of a fastforward.

For the moment, the merge does not support options, it will perform the merge with the default ones defined in GIT_MERGE_OPTS_INIT libgit2 constant.

Example:

>>> other_branch_tip = '5ebeeebb320790caf276b9fc8b24546d63316533'
>>> repo.merge(other_branch_tip)

You can now inspect the index file for conflicts and get back to the user to resolve if there are. Once there are no conflicts left, you can create a commit with these two parents.

>>> user = repo.default_signature
>>> tree = repo.index.write_tree()
>>> message = "Merging branches"
>>> new_commit = repo.create_commit('HEAD', user, user, message, tree,
                                    [repo.head.target, other_branch_tip])

Cherrypick

Note that after a successful cherrypick you have to run Repository.state_cleanup() in order to get the repository out of cherrypicking mode.

Lower-level methods

These methods allow more direct control over how to perform the merging. They do not modify the working directory and return an in-memory Index representing the result of the merge.

N-way merges

The following methods perform the calculation for a base to an n-way merge.

With this base at hand one can do repeated invokations of Repository.merge_commits() and Repository.merge_trees() to perform the actual merge into one tree (and deal with conflicts along the way).
