The convenient way to cherry-pick a commit is to use
|
|
:py:meth:`.Repository.cherrypick()`. It is limited to cherry-picking with a
|
|
working copy and on-disk index.
|
|
|
|
.. code-block:: bash
|
|
|
|
$> cd /path/to/repo
|
|
$> git checkout basket
|
|
$> git cherry-pick 9e044d03c
|
|
|
|
.. code-block:: python
|
|
|
|
repo = pygit2.Repository('/path/to/repo')
|
|
repo.checkout('basket')
|
|
|
|
cherry_id = pygit2.Oid('9e044d03c')
|
|
repo.cherrypick(cherry_id)
|
|
|
|
if repo.index.conflicts is None:
|
|
tree_id = repo.index.write_tree()
|
|
|
|
cherry = repo.get(cherry_id)
|
|
committer = pygit2.Signature('Archimedes', 'archy@jpl-classics.org')
|
|
|
|
repo.create_commit(basket.name, cherry.author, committer,
|
|
cherry.message, tree_id, [basket.target])
|
|
del basket # outdated, prevent from accidentally using it
|
|
|
|
repo.state_cleanup()
|
|
|

Cherry-picking a commit without a working copy
|
|
----------------------------------------------------------------------
|
|
|
|
This way of cherry-picking gives you more control over the process and works
|
|
on bare repositories as well as repositories with a working copy.
|
|
:py:meth:`~.Repository.merge_trees()` can also be used for other tasks, for
|
|
example `three-argument rebases`_.

.. code-block:: python

repo = pygit2.Repository('/path/to/repo')
|
|
|
|
cherry = repo.revparse_single('9e044d03c')
|
|
basket = repo.branches.get('basket')
|
|
|
|
base = repo.merge_base(cherry.oid, basket.target)
|
|
base_tree = cherry.parents[0].tree
|
|
|
|
index = repo.merge_trees(base_tree, basket, cherry)
|
|
tree_id = index.write_tree(repo)
|
|
|
|
author = cherry.author
|
|
committer = pygit2.Signature('Archimedes', 'archy@jpl-classics.org')
|
|
|
|
repo.create_commit(basket.name, author, committer, cherry.message,
|
|
tree_id, [basket.target])
|
|
del None # outdated, prevent from accidentally using it
