How can one dry run a git push to check whether one has write permissions to a remote?
提问by David
Is there a way to dry run a git pushto know whether the user has permissions to actually create a new remote branch? I'd like to be able to verify that all is good in regards to permissions for a bunch of repos where the user will attempt to create new branches before they are actually created so that I can dry run the full execution before actually doing it.
有没有办法试运行 agit push以了解用户是否有权实际创建新的远程分支？我希望能够验证在一堆 repos 的权限方面一切正常，用户将在实际创建新分支之前尝试创建新分支，以便我可以在实际执行之前先试运行完整执行。

Shawn Pierce wrotethe following about git push --dry-run:
肖恩·皮尔斯(Shawn Pierce)写了以下内容git push --dry-run：
A
--dry-rundoesn't send the commands the client would use from client to server, so the server can't tell the client if it would accept them or not. The entire--dry-runthing is client side only.
A
--dry-run不会将客户端将使用的命令从客户端发送到服务器，因此服务器无法告诉客户端它是否会接受它们。整个--dry-run事情只是客户端。
(my emphasis)
（我的重点）
So, if there is a way to check whether one has write permissions to a remote, git push --dry-runis definitely not it.
所以，如果有一种方法可以检查一个人是否对远程有写权限，git push --dry-run肯定不是。

Posting as an answer on the test I did where I don't think it works in my scenario. I'm creating a branch form another one without further changes
在我所做的测试中作为答案发布，我认为它在我的场景中不起作用。我正在从另一个分支创建一个分支，而无需进一步更改
git clone ....
git checkout master
git branch -f test master
git push --dry-run origin test
and it passed even though I have zero push permissions on this server/repo combo
即使我对此服务器/存储库组合的推送权限为零，它也通过了
To ssh://<server>/repo
* [new branch] test -> test
Pushing without dry-run hits the error condition I was expecting
在没有空运行的情况下推动达到了我期望的错误条件
git push origin test
Total 0 (delta 0), reused 0 (delta 0)
remote: Processing changes: refs: 1, done
To ssh://<server>/repo
! [remote rejected] test -> test (can not create new references)
error: failed to push some refs to 'ssh://<server>/repo'
