如何从git镜像克隆中排除拉取请求

Question

我想镜像克隆一个Bitbucket存储库到另一个Bitbucket存储库。 我用shell脚本管理它，它执行以下操作：

git clone --mirror <sourceUrl>
git remote set-url --push origin <targetUrl>
git push --mirror

现在我在推送时遇到以下错误，因为Bitbucket不允许推送拉取请求（在源Bitbucket上创建）：

remote: You are attempting to update refs that are reserved for Bitbucket's pull
remote: request functionality. Bitbucket manages these refs automatically, and they may
remote: not be updated by users.
remote:
remote: Rejected refs:
remote:         refs/pull-requests/21/from
remote:         refs/pull-requests/23/from
remote:         refs/pull-requests/23/merge
remote:         refs/pull-requests/24/from
remote:         refs/pull-requests/24/merge
To ...
 ! [remote rejected] refs/pull-requests/21/from -> refs/pull-requests/21/from (pre-receive hook declined)
 ! [remote rejected] refs/pull-requests/23/from -> refs/pull-requests/23/from (pre-receive hook declined)
 ! [remote rejected] refs/pull-requests/23/merge -> refs/pull-requests/23/merge (pre-receive hook declined)
 ! [remote rejected] refs/pull-requests/24/from -> refs/pull-requests/24/from (pre-receive hook declined)
 ! [remote rejected] refs/pull-requests/24/merge -> refs/pull-requests/24/merge (pre-receive hook declined)
error: failed to push some refs to '...'

我通过使用以下解决方法调整fetch refs，从http://christoph.ruegg.name/blog/git-howto-mirror-a-github-repository-without-pull-refs.html解决了问题。

我创建了一个新的裸存储库，并按以下方式调整配置：

[core]
    repositoryformatversion = 0
    filemode = true
    bare = true
[remote "origin"]
    fetch = +refs/heads/*:refs/heads/*
    fetch = +refs/tags/*:refs/tags/*
    url = <sourceUrl>
    mirror = true
    pushurl = <targetUrl>

然后我执行Git Pull和Git Push，一切都很好。

然而，变通方法并不是一个漂亮的解决方案，因为创建一个空的裸存储库，然后覆盖它是很奇怪的，所以我想要一个替代方案。

问题：

• 我可以使用“git clone --config”添加所需的获取配置（在git clone执行初始获取之前）但是我可以使用“git clone”命令删除原始的fetch = +refs/*:refs/*配置吗？ 这将解决最初拉取拉请求的问题
• 拉动后是否可以从裸存储库中删除拉取请求？
• 是否可以从推送中排除拉取请求？

感谢伊万。

他的命令解决了我的问题。 我只需要将“-r”参数添加到xargs以对空greps做出反应：

git show-ref | cut -d' ' -f2 | grep 'pull-request' | xargs -r -L1 git update-ref -d
