当您在 Git 存储库中运行“git add .git”时会发生什么？

虽然它似乎什么也没做，但它没有给出警告或错误消息。有什么想法吗？

来自 Git 源代码的评论：

/*
 * Read a directory tree. We currently ignore anything but
 * directories, regular files and symlinks. That's because git
 * doesn't handle them at all yet. Maybe that will change some
 * day.
 *
 * Also, we ignore the name ".git" (even if it is not a directory).
 * That likely will not change.
 */

实验看看如果我创建一个文件 .git 并尝试添加它会发生什么：
（在 Windows 上，当已经存在 .git 文件夹时，我无法创建文件 .git。我也可以在其他位置创建 .git一个子目录，但想尝试一下我之前没有使用过的 --git-dir 和 --work-tree 。允许我展示我可以添加 git 元数据文件夹，如下所示）

git --git-dir="c:/test" init
touch blah
git --git-dir="c:/test" --work-tree="." add .
git --git-dir="c:/test" --work-tree="." status ( shows blah added)
touch .git
git --git-dir="c:/test" --work-tree="." add .git ( no output as usual)
git --git-dir="c:/test" --work-tree="." status ( only blah shown)

所以是的， .git - 无论是目录还是文件，都会被 git 忽略。

如果我执行如下操作：

git --git-dir="c:/test" --work-tree="c:/test" add c:/test

所有元文件都会被添加。

因此，据我所知，只有 .git 被忽略，而不是 git 元数据文件夹（您通过 --git-dir 设置）。

Comment from Git source:

Experiment to see what happend if I create a file .git and try to add it:
(on Windows I cannot create a file .git when there is already a .git folder. I also could have created a .git elsewhere in a sub directory, but wanted to try out --git-dir and --work-tree which I haven't used before. After all I am experimenting. This also allows me to show that I can add the git metadata folder as seen below)

git --git-dir="c:/test" init
touch blah
git --git-dir="c:/test" --work-tree="." add .
git --git-dir="c:/test" --work-tree="." status ( shows blah added)
touch .git
git --git-dir="c:/test" --work-tree="." add .git ( no output as usual)
git --git-dir="c:/test" --work-tree="." status ( only blah shown)

So yeah, .git - be it directory or file, is ignored by git.

And if I do something like below:

git --git-dir="c:/test" --work-tree="c:/test" add c:/test

all the meta files get added.

So again, it is only .git that is ignored not the git metadata folder (that you set via --git-dir) as far as I can see.

简短的回答：没什么。

长答案：

laptop:Projects ctcherry$ mkdir test
laptop:Projects ctcherry$ cd test
laptop:test ctcherry$ git init .
Initialized empty Git repository in /Users/ctcherry/Projects/test/.git/
laptop:test ctcherry$ git add .git
laptop:test ctcherry$ git status
# On branch master
#
# Initial commit
#
nothing to commit (create/copy files and use "git add" to track)
laptop:test ctcherry$

Short answer: Nothing.

Long answer:

laptop:Projects ctcherry$ mkdir test
laptop:Projects ctcherry$ cd test
laptop:test ctcherry$ git init .
Initialized empty Git repository in /Users/ctcherry/Projects/test/.git/
laptop:test ctcherry$ git add .git
laptop:test ctcherry$ git status
# On branch master
#
# Initial commit
#
nothing to commit (create/copy files and use "git add" to track)
laptop:test ctcherry$
