运行git commit -a时，git pre-commit hook未运行

问题描述

我有一个本地预执行钩子执行，并在运行
git commit

时按预期停止提交

另外，如我所料，当我运行 git commit -n ...

$ b时，我可以绕过钩子$ b

但是，运行 git commit -am我的消息或者确实只是 git commit -a 似乎绕过了钩子，并允许处理提交。

任何想法可能会发生这种情况？

编辑：Hook below。

  PROJECT_ROOT =`git rev-parse --show-toplevel` 
 CHANGED =`git diff --stat  -  $ PROJECT_ROOT / myProj / myfile.ext | wc -l` 
 if [$ CHANGED -gt 0]; 
然后
 echomyfile.ext文件已更改，您确定要提交
 echo使用-n参数来处理此提交。 
 exit 1 
 fi 
  

解决方案

所以，这是用户错误。

钩子在两个实例中都运行，但是当我使用逻辑来检测文件中的更改时，一个命令被提供。

检查远程回购是否有用。

CHANGED =`git diff origin / master --stat - $ PROJECT_ROOT / myProj / myfile.ext | wc -l`


编辑：感谢@torek，更合适的检查方式对于一个变化是：

  CHANGED =`git diff --cached --stat  -  $ PROJECT_ROOT / myProj / myfile.ext | wc -l` 
  

I have a local pre-commit hook which executes, and stops the commit as expected when I rungit commit

Also, as expected, I can bypass the hook when I run git commit -n ...

However, running git commit -am "My message" or indeed, just git commit -a seems to bypass the hook and allow the commit to be processed.

Any idea why this may be happening?

Edit: Hook below.

PROJECT_ROOT=`git rev-parse --show-toplevel`
CHANGED=`git diff --stat -- $PROJECT_ROOT/myProj/myfile.ext | wc -l`
if [ $CHANGED -gt 0 ];
then
    echo "myfile.ext file has changed, are you sure you want to commit"
    echo "Use the -n parameter to process this commit."
    exit 1
fi

解决方案

So, it was user error..

The hook was running in both instances, however the logic I used to detect a change in my file didn't work when the -a command was supplied.

Checking against the remote repo did the trick.

CHANGED=`git diff origin/master --stat -- $PROJECT_ROOT/myProj/myfile.ext | wc -l`

edit: thanks to @torek, a more appropriate way to check for a change is:

CHANGED=`git diff --cached --stat -- $PROJECT_ROOT/myProj/myfile.ext | wc -l`
