c++ - git 和 libgit : unable to create file (No such file or directory)

Question

我正在使用 libgit2(在 C++ 中)创建一个 git 存储库和一个提交。 它工作正常，但是， checkout 会破坏所有本地文件。

但是它们似乎仍然存在于 repo 中。这就是我尝试查看存储库时得到的结果。

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by performing another checkout.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -b with the checkout command again. Example:

  git checkout -b new_branch_name

现在，“奇怪”的是，如果我事先手动创建 db\xx 目录，checkout -f 会起作用。

更奇怪的是，整个事情在 MacOSx 下按原样运行，但在 Windows 下却不行......

知道这里发生了什么吗？

Answer 1

$ git checkout a63cd37ef7d7228053b875e396531d367e2ea745
D       "db\\32\\879a83081b8d0b4ef41a37b9e28138"

看到报价了吗？ git 将使用 C 字符串文字约定来显示其中包含不寻常字符的文件名。您的存储库记录了一个以该 C 字符串作为名称的文件——包括反斜杠。

:、\ 和/ 并不是到处都是无效的，

$ touch "db\\32\\879a83081b8d0b4ef41a37b9e28138"
$ ls
db\32\879a83081b8d0b4ef41a37b9e28138
$ git add .
$ git ls-files
"db\\32\\879a83081b8d0b4ef41a37b9e28138"
$ 

但它们不可移植。

大致来说，Windows文件系统保留\和:，Mac，:，Unix，/。可能仍有系统保留;。
