我正在尝试使用pygit2实现一些'瓷器'命令。看来我在实施拉动时遇到了一些障碍。特别是最简单的拉动案例,快进。
设定:
我有两个git回购。一个'远程'和一个'本地'。我在远程仓库上进行一次提交,然后使用pygit2的clone_repository()
创建本地仓库。我在遥控器上进行后续提交,然后尝试运行下面列出的pull()
功能。
我的实施:
def pull(repo, remote_name='origin'):
for remote in repo.remotes:
if remote.name == remote_name:
remote.fetch()
remote_master_id = repo.lookup_reference('refs/remotes/origin/master').target
merge_result, _ = repo.merge_analysis(remote_master_id)
# Up to date, do nothing
if merge_result & pygit2.GIT_MERGE_ANALYSIS_UP_TO_DATE:
return
# We can just fastforward
elif merge_result & pygit2.GIT_MERGE_ANALYSIS_FASTFORWARD:
print repo.head.target
print repo.status()
master_ref = repo.lookup_reference('refs/heads/master')
master_ref.set_target(remote_master_id)
repo.head.set_target(master_ref)
repo.checkout_head()
print repo.status()
elif merge_result & pygit2.GIT_MERGE_ANALYSIS_NORMAL:
repo.merge(remote_master_id)
print repo.index.conflicts
assert repo.index.conflicts is None, 'Conflicts, ahhhh!'
user = repo.default_signature
tree = repo.index.write_tree()
commit = repo.create_commit('HEAD',
user,
user,
'Merge!',
tree,
[repo.head.target, remote_master_id])
repo.state_cleanup()
else:
raise AssertionError('Unknown merge analysis result')
在我的代码执行快进位后,我的索引不再干净,我不明白为什么。看一下git-log,它看起来很成功。我的头和主分支现在指向远程仓库上的最新提交。但是,为什么在运行remote_repo_test.txt
的过程中修改了set_target()
。

第一个解决方案(不推荐):
你应该不这样做。以这种方式失去工作是可能的。但是,它可以作为一个hacky解决方案。
master_ref = repo.lookup_reference('refs/heads/master')
master_ref.set_target(remote_master_id)
# Terrible hack to fix set_target() screwing with the index
repo.reset(master_ref.target, pygit2.GIT_RESET_HARD)
第二个解决方案:
这个似乎很有希望。经过多次试验和错误,我可能已经找到了解决方案。如果您签出要在之前 的树对象,则更新引用它可以正常工作。索引是干净的,就像您在运行git pull
或git merge
repo.checkout_tree(repo.get(remote_master_id))
master_ref = repo.lookup_reference('refs/heads/master')
master_ref.set_target(remote_master_id)
repo.head.set_target(remote_master_id)
