不明白 gitignore 提示消息

Question

我正在尝试理解以下消息：

cap@MacPro-2 wiki-dir % git add -A -- /Users/cap/DOCKER/dante-wiki/volumes/full/content/wiki-dir/extensions/DanteBread/breadCrumbs.js
The following paths are ignored by one of your .gitignore files:
extensions
hint: Use -f if you really want to add them.
hint: Turn this message off by running
hint: "git config advice.addIgnoredFile false"

我觉得令人困惑的问题如下：

在我发出

git add

命令之前，我得到了

cap@MacPro-2 wiki-dir % git status
On branch master
Your branch is up to date with 'origin/master'.

Changes to be committed:
  (use "git restore --staged <file>..." to unstage)
    modified:   extensions/DanteBread/COPYING

Changes not staged for commit:
  (use "git add <file>..." to update what will be committed)
  (use "git restore <file>..." to discard changes in working directory)
    modified:   extensions/DanteBread/breadCrumbs.js

然后我得到了

cap@MacPro-2 wiki-dir % git status
On branch master
Your branch is up to date with 'origin/master'.

Changes to be committed:
  (use "git restore --staged <file>..." to unstage)
    modified:   extensions/DanteBread/COPYING
    modified:   extensions/DanteBread/breadCrumbs.js

所以Git事实上确实将添加的文件添加到了暂存区，虽然我没有使用

-force

。

此外，单独的

git check-ignore

表明该文件not 被忽略。

那么为什么我会收到此警告？为什么

git add

声称路径

extensions

被忽略，而

git check-ignore

却找不到这个路径？

Answer 1

我可以在我的 Linux 系统上重现同样的问题，使用 git 版本 2.42.0 :

设置：

mkdir repo
cd repo
git init
mkdir -p dir1
echo foobarfoobar > dir1/versioned.txt
git add dir1/versioned.txt && git commit -m "created dir1/versioned.txt"
echo dir1 > .gitignore
git add .gitignore && git commit -m "ignoring dir1"

现在：

• 运行

  git check-ignore dir1/versioned.txt

  将产生空输出，但运行

  git check-ignore dir1/ignored.txt

  甚至

  git check-ignore dir1/doesnt_exist.txt

  将向我显示某些内容被忽略：

# check-ignore does not mention versioned.txt:
$ git check-ignore dir1/versioned.txt
# it does catch ignored files, or even path that don't exist yet and are below dir1/:
$ touch dir1/ignored.txt
$ git check-ignore dir1/ignored.txt
dir1/ignored.txt
$ git check-ignore dir1/doesnt_exist.txt dir1/no_dir/no_file.txt
dir1/doesnt_exist.txt
dir1/no_dir/no_file.txt

• 修改版本化文件会产生与您的相同的行为：该文件（正确）在

  git status

  中列出，尽管它确实被添加，但我在运行时收到警告

  git add

  ：

$ echo "barfoobarfoo" >> dir1/versioned.txt

$ git status
On branch master
Changes not staged for commit:
  (use "git add <file>..." to update what will be committed)
  (use "git restore <file>..." to discard changes in working directory)
    modified:   dir1/versioned.txt

no changes added to commit (use "git add" and/or "git commit -a")


$ git add dir1/versioned.txt 
The following paths are ignored by one of your .gitignore files:
dir1
hint: Use -f if you really want to add them.
hint: Turn this message off by running
hint: "git config advice.addIgnoredFile false"

$ git status
On branch master
Changes to be committed:
  (use "git restore --staged <file>..." to unstage)
    modified:   dir1/versioned.txt
