Question

如果满足某个条件，我就会中止git commit。

check if my commit has 'import pdb' in emacs/git?

#!/bin/sh

git diff --cached --no-renames --name-status --diff-filter=AM |
  while read st file; do
    case "$file" in
    *.py)
        if git show ":$file" |
          grep -E "^[^#]*\bimport[[:space:]]+pdb\b"; then
            echo "$file: has import pdb"
            exit 1
        fi;;
    esac
done

git diff --cached --name-status --diff-filter=ACM | while read st file; do
    if grep "#[[:space:]]*@test" "$file"; then
        echo "$file: has @test"
        exit 1
    fi
done

代码运行正常，我可以看到日志＆＃34; ...有导入pdb＆＃34; 但下一行exit 1不会中止git提交。

过去工作正常，但在某些时候停止了工作。我是关于git 1.9.1

输出

代码的第一部分读起来像

something | while ...; do ... exit 1; done

由于管道必然涉及两个进程，因此shell必须派一个子shell来执行while循环。因此，{em> subshell 中存在状态为1的exit 1，并返回到您的父shell，忽略返回代码。

您想在|| exit $?关键字之后添加done，如下所示：

something | while ...; do ... exit 1; done || exit $?

请注意，这实际上不是Git问题，而是shell问题。

预提交中的退出1不会中止git commit吗？
