如何使用 libgit2sharp 创建从本地到远程的新分支？

Question

我想使用 libgit2sharp 在 git 上创建和删除一个分支。我想出了这段代码，但它在repo.Network.Push(localBranch, pushOptions); 处引发错误

using (var repo = new Repository(GIT_PATH))
{
    var branch = repo.CreateBranch(branchName);

    var localBranch = repo.Branches[branchName];

    //repo.Index.Stage(GIT_PATH);
    repo.Checkout(localBranch);
    repo.Commit("Commiting at " + DateTime.Now);

    var pushOptions = new PushOptions() { Credentials = credentials };

    repo.Network.Push(localBranch, pushOptions); // error

    branch = repo.Branches["origin/master"];
    repo.Network.Push(branch, pushOptions);
}

错误信息是The branch 'buggy-3' ("refs/heads/buggy-3") that you are trying to push does not track an upstream branch.

我尝试在互联网上搜索此错误，但没有找到可以解决此问题的解决方案。是否可以使用 libgit2sharp 做到这一点？

Answer 1

您必须将本地分支与要推送的远程关联。

例如，给定一个已经存在的"origin" 远程：

Remote remote = repo.Network.Remotes["origin"];

// The local branch "buggy-3" will track a branch also named "buggy-3"
// in the repository pointed at by "origin"

repo.Branches.Update(localBranch,
    b => b.Remote = remote.Name,
    b => b.UpstreamBranch = localBranch.CanonicalName);

// Thus Push will know where to push this branch (eg. the remote)
// and which branch it should target in the target repository

repo.Network.Push(localBranch, pushOptions);

// Do some stuff
....

// One can call Push() again without having to configure the branch
// as everything has already been persisted in the repository config file
repo.Network.Push(localBranch, pushOptions);

注意： Push() 公开了其他 overloads，允许您动态提供此类信息，而无需将其存储在配置中。
