How to push to upstream in Git?
提问by typos
I have a project with a few friends in GitLab, and there is of course the master branch, and there are some others too. When I cloned the repository, I created also an upstream with the command git remote add upstream ....
我和几个朋友在 GitLab 有一个项目，当然有 master 分支，还有一些其他的。当我克隆存储库时，我还使用命令创建了一个上游git remote add upstream ...。
Then, I issued the git fetch upstream. Followed by git checkout upstream/test1. Now, if I type git branch -a, I get an output like this:
然后，我发布了git fetch upstream. 紧随其后git checkout upstream/test1。现在，如果我输入git branch -a，我会得到这样的输出：
* (HEAD detached at upstream/test1)
master
remotes/origin/HEAD -> origin/master
remotes/origin/master
remotes/upstream/test1
remotes/upstream/master
This is all fine, but then I did some changes to the code in my upstream/test1branch. I don't want yet to push them to origin/test1, but I want to be able to push my changes to upstream/test1so that my other friend can see it. But, if I issue the following set of commands:
这一切都很好，但后来我对我的upstream/test1分支中的代码进行了一些更改。我还不想将它们推送到origin/test1，但我希望能够将我的更改推送到 ，upstream/test1以便我的其他朋友可以看到它。但是，如果我发出以下命令集：
git add .
git commit -m "Sample message"
After the commit I got the message:
提交后，我收到消息：
[detached HEAD 4f20e95] Sample message
5 files changed, 12 insertions(+), 1 deletions(-)
And the hash value changes to 4f20e95in my command prompt. Then if I do git push, I get the following error messages:
并且哈希值4f20e95在我的命令提示符中更改为。然后，如果我这样做git push，我会收到以下错误消息：
fatal: You are not currently on a branch.
To push the history leading to the current (detached HEAD)
state now, use
git push origin HEAD:<name-of-remote-branch>
How can I push to my upstream branch without actually pushing to origin.
如何在不实际推送到原点的情况下推送到我的上游分支。
回答by Scott Weldon
The branch upstream/test1is a remote tracking branch, which can't be updated manually. Such branches track branches on remote servers, and are only updated during git fetch/git push.
该分支upstream/test1是远程跟踪分支，无法手动更新。这样的分支跟踪远程服务器上的分支，并且只在git fetch/期间更新git push。
Instead, check out a new local branch first:
相反，首先检查一个新的本地分支：
git checkout -b test1 upstream/test1
And commit there as usual. Since you have already committed, instead do:
并像往常一样在那里提交。既然你已经提交了，那么做：
git checkout -b test1 4f20e95
When you are ready, push to upstream:
准备好后，请推至upstream：
git push upstream test1
When you do a plain git push, Git uses default values for the remote and branch to push based on certain config options. However, if you aren't on a branch (thus getting the detached HEADmessage), then Git doesn't know what branch to push, thus giving you the error you received.
当您执行普通 时git push，Git 使用远程和分支的默认值根据某些配置选项进行推送。但是，如果您不在分支上（因此会收到detached HEAD消息），则 Git 不知道要推送哪个分支，从而为您提供收到的错误。
