Question

我想保护我的git存储库，因此只能覆盖非主分支。有没有办法只保护选定的分支？

Answer 1

这是我为自己编写的更新钩子（复制到钩子/更新）。默认情况下，此脚本拒绝所有非快进更新，但允许它们用于显式配置的分支。它应该很容易被反转，以便除了主分支以外的所有允许非快进更新。

#!/bin/sh
#
# A hook script to block non-fast-forward updates for branches that haven't
# been explicitly configured to allow it. Based on update.sample.
# Called by "git receive-pack" with arguments: refname sha1-old sha1-new
#
# Config
# ------
# hooks.branch.<name>.allownonfastforward
#   This boolean sets whether non-fast-forward updates will be allowed for
#   branch <name>. By default they won't be.

# --- Command line
refname="$1"
oldrev="$2"
newrev="$3"

# --- Safety check
if [ -z "$GIT_DIR" ]; then
        echo "Don't run this script from the command line." >&2
        echo " (if you want, you could supply GIT_DIR then run" >&2
        echo "  $0 <ref> <oldrev> <newrev>)" >&2
        exit 1
fi

if [ -z "$refname" -o -z "$oldrev" -o -z "$newrev" ]; then
        echo "Usage: $0 <ref> <oldrev> <newrev>" >&2
        exit 1
fi

# --- Check types
# if $newrev is 0000...0000, it's a commit to delete a ref.
zero="0000000000000000000000000000000000000000"
if [ "$newrev" = "$zero" ]; then
        newrev_type=delete
else
        newrev_type=$(git cat-file -t $newrev)
fi

case "$refname","$newrev_type" in
        refs/tags/*,commit)
                # un-annotated tag
                ;;
        refs/tags/*,delete)
                # delete tag
                ;;
        refs/tags/*,tag)
                # annotated tag
                ;;
        refs/heads/*,commit)
                # branch
                # git rev-list doesn't print anything on fast-forward updates
                if test $(git rev-list "$newrev".."$oldrev"); then
                        branch=${refname##refs/heads/}
                        nonfastforwardallowed=$(git config --bool hooks.branch."$branch".allownonfastforward)

                        if [ "$nonfastforwardallowed" != "true" ]; then
                                echo "hooks/update: Non-fast-forward updates are not allowed for branch $branch"
                                exit 1
                        fi
                fi
                ;;
        refs/heads/*,delete)
                # delete branch
                ;;
        refs/remotes/*,commit)
                # tracking branch
                ;;
        refs/remotes/*,delete)
                # delete tracking branch
                ;;
        *)
                # Anything else (is there anything else?)
                echo "hooks/update: Unknown type of update to ref $refname of type $newrev_type" >&2
                exit 1
                ;;
esac

Answer 2

您可以使用GitEnterprise设置每个分支的权限（admin），以使用细粒度的访问权限阻止非快速推送。

如果您需要阻止所有分支的历史记录更改，git config --system receive.denyNonFastForwards true将完成此任务。

Answer 3

This SO answer会为您提供所需的信息。只需编辑它以应用于主分支：

#!/bin/sh
# lock the master branch for pushing
refname="$1"

if [ "$refname" = "refs/heads/master" ]
then
    echo "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX"
    echo "You cannot push to the master branch."
    echo "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX"
    exit 1
fi
exit 0

<强>更新
这将阻止所有推送到主分支，包括快进。

Answer 4

您可以通过配置denyNonFastForwards

来阻止非快进更新

git config --system receive.denyNonFastForwards true

但它适用于所有分支机构。有关详细信息，请参阅ProGit

Answer 5

我认为这取决于您在服务器端使用什么来访问您的存储库。有一些服务器应用程序支持每个分支的权限，如Gerrit或Gitlab（但是，我不确定Gitlab是否支持您的用例）。 Gerrit支持它，因为我在公司使用类似的工作流程。

也许Gitolite也支持它（这就是Gitlab在幕后使用的），它更容易设置，但没有像Gerrit或Gitlab这样的网络界面。

补充评论：GitEnterprise，正如所建议的，也是一个很好的解决方案，但是我的建议是合适的，如果你有自己的服务器（这在许多公司很常见）。

Answer 6

如果允许您修改服务器，则可以在服务器上启用快速转发。

ssh ip 'echo $"[receive]
    denyDeletes = false
    denyNonFastForwards = false" >> /path/to/repo/config'
#then git push -f origin master

这里是Tanu Kaskinen脚本的修改，允许对分支名称进行通配符处理。我们使用名称以“ d /”开头的分支来指定“开发”分支。我想要一种允许对这些d /分支进行非快速更新的方法：

   refs/heads/*,commit)
            # branch
            # git rev-list doesn't print anything on fast-forward updates

            if [[ $(git rev-list "$newrev".."$oldrev") ]]; then
                    branch=${refname##refs/heads/}
                    if [[ "$branch" =~ ^d/ ]] ; then
                      echo "Non-fast-forward update allowed on d/ branch"
                      nonfastforwardallowed="true";
                    else
                      #look for a specific config setting
                      nonfastforwardallowed=$(git config --bool  hooks.branch."$branch".allownonfastforward)
                    fi


                    if [ "$nonfastforwardallowed" != "true" ]; then
                            echo "hooks/update: Non-fast-forward updates are not allowed for branch $branch"
                            exit 1
                    fi
            fi

如何在git中阻止非快速推送到选定的分支？
