如何從git鏡像克隆中排除拉取請求

Question

我想鏡像克隆一個Bitbucket存儲庫到另一個Bitbucket存儲庫。 我用shell腳本管理它，它執行以下操作：

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

現在我在推送時遇到以下錯誤，因為Bitbucket不允許推送拉取請求（在源Bitbucket上創建）：

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 '...'

我通過使用以下解決方法調整fetch refs，從http://christoph.ruegg.name/blog/git-howto-mirror-a-github-repository-without-pull-refs.html解決了問題。

我創建了一個新的裸存儲庫，並按以下方式調整配置：

[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>

然后我執行Git Pull和Git Push，一切都很好。

然而，變通方法並不是一個漂亮的解決方案，因為創建一個空的裸存儲庫，然后覆蓋它是很奇怪的，所以我想要一個替代方案。

問題：

• 我可以使用“git clone --config”添加所需的獲取配置（在git clone執行初始獲取之前）但是我可以使用“git clone”命令刪除原始的fetch = +refs/*:refs/*配置嗎？ 這將解決最初拉取拉請求的問題
• 拉動后是否可以從裸存儲庫中刪除拉取請求？
• 是否可以從推送中排除拉取請求？

感謝伊萬。

他的命令解決了我的問題。 我只需要將“-r”參數添加到xargs以對空greps做出反應：

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