Git 预推钩

**** git push 在检查远程状态后,但在推送任何内容之前调用 pre-push 脚本。如果此脚本以非零状态退出,则不会推送任何内容。

使用以下参数调用此挂钩:

 $1 -- Name of the remote to which the push is being done (Ex: origin)
 $2 -- URL to which the push is being done (Ex: https://<host>:<port>/<username>/<project_name>.git)

有关正在推送的提交的信息作为行提供给表单中的标准输入:

<local_ref> <local_sha1> <remote_ref> <remote_sha1>

样本值:

local_ref = refs/heads/master
local_sha1 = 68a07ee4f6af8271dc40caae6cc23f283122ed11
remote_ref = refs/heads/master
remote_sha1 = efd4d512f34b11e3cf5c12433bbedd4b1532716f

下面的示例预推脚本是从默认的 pre-push.sample 中获取的,当使用 git init 初始化新的存储库时会自动创建

# This sample shows how to prevent push of commits where the log message starts
# with "WIP" (work in progress).

remote="$1"
url="$2"

    if [ "$local_sha" = $z40 ]
    then
        # Handle delete

    else
        if [ "$remote_sha" = $z40 ]
        then
            # New branch, examine all commits
            range="$local_sha"
        else

        then
            echo >&2 "Found WIP commit in $local_ref, not pushing"
            exit 1
