git fatal：对象错误：浅<SHA-1>

问题描述

我正试图解开存储库：

% /bin/git clone --shallow-since='3 years' 'https://github.com/RobertAudi/zsh-hooks'
Cloning into 'zsh-hooks'...

% git fetch --unshallow origin
fatal: error in object: unshallow 9301f4e3a16df8e7cf8f37b5b93a7b925d8c8bee
fatal: the remote end hung up unexpectedly

我还尝试将原点的https更改为git和ssh，但没有任何乐趣。

设置：

git config http.postBuffer 524288000

没有效果。

我在本地仓库中只有5次提交，并且尝试增加深度也失败了：

% git fetch --depth=10
fatal: error in object: unshallow 9301f4e3a16df8e7cf8f37b5b93a7b925d8c8bee

进一步的调试信息：

我正在使用：

% /bin/git --version
git version 2.28.0

解决方法

FWIW：克隆该存储库时，我可以重现您的问题。

我在克隆服务器上运行过一次git repack -aldf（在您链接的问题中提到），这使我的下一个git fetch --unshallow工作正常。

仔细研究一下：git repack -d足以解决问题。

我没有得到我运行的git repack命令背后的所有含义；我认为您可以将这个确切的问题提交到git的邮件列表中。
