Git如何检测整个文件夹被删除/移动

Kak*_*ait 9 git

Git基于内容而没有文件,因此我目前了解以下行为,但我想知道是否有特殊选项或黑客来检测这样的事情:

git init
mkdir -p foo/bar
echo "test" foo/a.txt
echo "test2" foo/bar/b.txt
git add -A
git commit -m "test"

rm -fr foo
git add -A
git commit -m "delete whole dir"
git log --name-status

当我检查记录,Git将无法说清楚我foo被删除,但所有的文件foo/a.txtfoo/bar/b.txt被删除

    delete whole dir

因此,如果我创建以下提交:

mkdir -p foo/bar
echo "test" > foo/a.txt
echo "test2" > foo/bar/b.txt
echo "test3" > foo/bar/c.txt
git add -A
git commit -m "test2"

rm -f foo/a.txt foo/bar/b.txt
git add -A
git commit -m "delete just 2 files"
git log --name-status

name-status提交delete whole dirdelete just 2 files类似之间

删除整个目录时有没有办法检测差异?

假设存储库中的示例树结构为:

Initial commit

Changes to be committed:
  (use "git rm --cached <file>..." to unstage)

    new file:   a/b/c/d/e/q.txt
    new file:   a/b/c/m.txt
    new file:   a/b/c/n.txt
    new file:   a/b/f/o.txt
    new file:   a/b/f/p.txt
    new file:   a/b/k.txt
    new file:   a/b/z.txt

Commit 3b53f16eb2fd7d3d605180ccabcfa71eb9e9225a 是看到文件夹“a/b/c”消失的文件夹,因为其中的最后一个文件被删除。

要在删除文件夹 a/b/c 时查找提交的 SHA#,您可以使用以下组合来查找涉及“a/b/c”文件夹的最后一次提交:

#> git log --name-status -- a/b/c 
Run Code Online (Sandbox Code Playgroud)

#> git ls-tree -r [commit] -- a/b/c
Run Code Online (Sandbox Code Playgroud)

就像是:

for cmt in $(git log --pretty=%H -- a/b/c); \
    do X=$(git ls-tree -r "${cmt}" -- a/b/c); \
    [[ -z "${X}" ]] && echo "The folder a/b/c has been deleted in commit: ${cmt}"; \
done

输出:

The folder a/b/c has been deleted in commit: 3b53f16eb2fd7d3d605180ccabcfa71eb9e9225a

以简单的BASH脚本的形式(我将其命名为deleted.sh,应该具有可执行权限):

#!/bin/bash

P="$1"
GIT=$(which git)

for cmt in $($GIT log --pretty=%H -- "${P}"); do
    X=$($GIT ls-tree -r "${cmt}" -- "${P}");
    [[ -z "${X}" ]] && echo "The folder a/b/c has been deleted in commit: ${cmt}";
done

它是如何工作的

历史上第一次提交,树中没有与文件夹路径匹配的文件,应该可以。

这就是 shell 脚本正在做的事情。

它在历史记录中向后迭代,检索与文件夹中任何文件相关的所有 SHA#,然后在这些提交中找到第一个,在 Git 树中没有任何与提供的路径匹配的文件。

事实上,该提交出现在要检查的列表中,确保其中存在涉及该文件夹的更改。

事实上,没有与树中的文件夹匹配的文件(过滤后的“ls-tree”返回空字符串),确保这是该文件夹中最后一个文件已被删除的提交。
