如何迁移不再被识别为 git 存储库的旧 git 存储库？

Question

我刚刚发现我有几个旧的 Git 存储库在过去十年中没有进行过修改 - 并且这些不再被识别为 Git 存储库。

其中一个无法识别的存储库包含以下文件：

.git/config

文件的内容是：

[core]
    repositoryformatversion = 0
    filemode = true
    bare = false
    logallrefupdates = true
    ignorecase = true
    precomposeunicode = true

运行

git status

产量：

$ git status
fatal: not a git repository (or any of the parent directories): .git
$

另一个仍被识别为存储库的目录包含文件：

.git/config

文件包含：

    filemode = true
    bare = false
    logallrefupdates = true
    ignorecase = true
    precomposeunicode = true
[remote "origin"]
    url = [email protected]:jleffler/scc-snapshots
    fetch = +refs/heads/*:refs/remotes/origin/*
[branch "master"]
    remote = origin
    merge = refs/heads/master

git status

的输出是：

$ git status
On branch master
Your branch is up to date with 'origin/master'.

nothing to commit, working tree clean

我不确定显着差异是什么。

• 你能确定问题出在哪里吗？
• 除了下载旧版本的 Git、构建并运行它之外，有没有办法解决这个问题？
• 这是否可以解决问题——或者我只需要一次重建一个签入历史记录，在使用旧 Git 的旧存储库和使用当前系统提供的 Git 构建的新存储库之间进行复制？

我不知道这是否重要，但我现在在配备 Apple M2 Pro 芯片的 MacBook Pro 上运行，运行 macOS Sonoma 14.5。 创建存储库时，我使用的是配备 Intel 芯片的 MacBook Pro 机器。 我怀疑这是否重要，但我现在使用

zsh

作为我之前使用

bash

的 shell。

Git 的当前版本是

/usr/bin/git

，它报告版本“git version 2.39.3 (Apple Git-146)”。

Answer 1

我将建议一个非常简单的解决方案。假设您正在查看的是一个 bare 存储库，已删除其

refs

目录。然后你可以像这样解决问题：

• 手动为麻烦的

  .git

  目录提供一个

  refs

  子目录。
• 手动为该

  refs

  子目录提供一个

  heads

  子目录和一个

  tags

  子目录。

这些目录将为空。尽管如此，这应该足以让 Git 将其视为 Git 存储库；你可以很容易地检验这个假设。

如果that有效，则在其他地方创建一个新的空文件夹，

cd

放入其中，然后说

git clone /path/to/that/.git

结果将是一个可用的工作树。
