git钩防止合并特定分支

问题描述

我有两个分支，一个生产分支和一个主分支.我想防止合并到生产的任何新分支，这些分支从 master 和master 自身签出.

I have two branches, a production branch, and a master branch. I want to prevent merging into production any new branch that checked out from master and master itself.

有一个git pre钩子可以帮上忙吗?

There is a git pre hook that can help with that?

推荐答案

• 在.git/hooks/文件夹中创建prepare-commit-msg
• 设置chmod权限:chmod +x .git/hooks/prepare-commit-msg
• 禁用快进合并:git config branch.master.mergeoptions "--no-ff"
• create the prepare-commit-msg into your .git/hooks/ folder
• make chmod permissions: chmod +x .git/hooks/prepare-commit-msg
• disable fast-forward merges: git config branch.master.mergeoptions "--no-ff"

.git/hooks/prepare-commit-msg

#!/usr/bin/env ruby

# Only for exceptions. In your case is empty array
WHITELIST_BRANCH = ["hotfix"]

def merge?
  ARGV[1] == "merge"
end

def into_master?
  current_branch = `git branch | grep '*' | sed 's/* //'`.chop
  current_branch == "master"
end

def merge_msg
  @msg ||= `cat .git/MERGE_MSG`
end

def from_branch
  @from_branch = merge_msg.match(/Merge branch '(.*?)'/)[1]
end

def whitelist_branch?
  WHITELIST_BRANCH.include?(from_branch)
end

if merge? && into_master? && !whitelist_branch?
  out = `git reset --merge`
  puts
  puts " Fail #{from_branch} into the *master* branch "
  puts
  puts " run the following command now to discard your working tree changes:"
  puts
  puts " git reset --merge"
  puts
  exit 1
end

在此代码中，仅WHITELIST_BRANCH可用于合并

In this code only WHITELIST_BRANCH is available to merge
