使用Pygit2实现拉
作者:互联网
我正在尝试使用pygit2实现一些“瓷器”命令.似乎在实施pull时遇到了一些障碍.特别是最容易拉的情况,就是快进.
设定:
我有两个git repos.一个“远程”和一个“本地”.我对远程仓库进行一次提交,然后使用pygit2的clone_repository()创建本地仓库.我在遥控器上进行了后续提交,然后尝试运行下面概述的pull()函数.
我的实现:
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')
在执行代码的快进位后,索引不再干净,我也不知道为什么.查看git-log,看起来很成功.我的头和master分支现在指向远程仓库中的最新提交.但是,为什么在运行set_target()的过程中修改了remote_repo_test.txt.
输出:
拉式打印语句:
abfe58ce5098e106a14263df725247bc1f4b22d2
{}
{'remote_repo_test.txt': 2}

有什么想法吗?
解决方法:
第一种解决方案(不推荐):
您不应该这样做.这样可能会丢失工作.但是,它可以作为一种骇人听闻的解决方案.
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)
第二种解决方案:
这似乎很有希望.经过反复尝试,我可能找到了解决方案.如果在更新引用之前签出要定位的树对象,它将起作用.索引很干净,就像您运行git pull或git merge所期望的一样
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)
