仅在添加新标签后才在接收后触发某些内容 [英] Trigger something in post-receive only when new tag is added

问题描述

当仅将新标签推入存储库时，我想在GIT的post-receive钩子中执行一些操作.如何做到这一点?

I want to do some action in GIT's post-receive hook when only new tag is pushed to the repository. How to accomplish this?

谢谢

解决方案(JanKrüger的回答)

新标签的$oldrev等于零.删除的标记的$newrev等于零.对于这两个$ref，值均以refs/tags/开头.

New tag has $oldrev equalled zeroes. Removed tag has $newrev equalled zeroes. For both $ref value starts with refs/tags/.

#!/bin/sh
#

read oldrev newrev ref

if [[ "0000000000000000000000000000000000000000" == $oldrev ]] && [[ $ref == refs\/tags\/* ]];
then
    echo "New tag added"
fi

推荐答案

post-receive挂钩接收stdin上有关在该操作中更新的所有ref(分支，标签等)的信息.每行具有以下格式，摘自 githooks联机帮助页:

The post-receive hook receives information on stdin about all the refs (branches, tags, ...) that were updated in that operation. Each line has the following format, taken from the githooks manpage:

<old-value> SP <new-value> SP <ref-name> LF

这将是创建新标签的示例:

So this would be an example of a new tag being created:

0000000000000000000000000000000000000000 0123456789abcdef0123456789abcdef01234567 refs/tags/mytag

您只需要阅读stdin并检查行是否与此格式匹配.基本上，第一个单词"全为零，第三个单词以refs/tags/开头.

You simply need to read from stdin and check whether a line matches this format. Basically the first "word" is all zeroes and the third word starts with refs/tags/.
