禁止删除git中的master分支 [英] Disallow deletion of master branch in git

问题描述

我正在尝试设置一个git钩子，该钩子将禁止任何人删除我们存储库中的master，alpha和beta分支.有人能帮忙吗?我从来没有做过git hook，所以我不想在没有一点帮助的情况下尝试自己开发自己的运气.

I’m trying to setup a git hook that will disallow anyone to delete the master, alpha, and beta branches of our repository. Can anyone help with this? I have never done a git hook, so I don’t want to try my luck in developing my own without a little help.

推荐答案

带有pre-receive钩子的简单明了.假设您使用的是裸露的中央存储库，请将以下代码放置在中，请不要忘记使用chmod +x your-repo.git/hooks/pre-receive.

Straightforward with a pre-receive hook. Assuming you're using a bare central repository, place the following code in your-repo.git/hooks/pre-receive, and don't forget to chmod +x your-repo.git/hooks/pre-receive.

#! /usr/bin/perl

# create: 00000... 51b8d... refs/heads/topic/gbacon
# delete: 51b8d... 00000... refs/heads/topic/gbacon
# update: 51b8d... d5e14... refs/heads/topic/gbacon

my $errors = 0;

while (<>) {
  chomp;

  next
    unless m[ ^
              ([0-9a-f]+)       # old SHA-1
              \s+
              ([0-9a-f]+)       # new SHA-1
              \s+
              refs/heads/(\S+)  # ref
              \s*
              $
            ]x;

  my($old,$new,$ref) = ($1,$2,$3);

  next unless $ref =~ /^(master|alpha|beta)$/;

  die "$0: deleting $ref not permitted!\n"
    if $new =~ /^0+$/;
}

exit $errors == 0 ? 0 : 1;
