如何确定分支是否包含带有TFS WebAPI客户端库的提交?

没有对应于git branch--contains命令的任何WebAPI客户端库。

但是作为一种解决方法,您可以直接在C代码中运行git命令。

string gitCommand = "git";
string gitAddArgument = @"add -A" ;
string gitCommitArgument = @"commit ""explanations_of_changes"" "
string gitPushArgument = @"push our_remote"

Process.Start(gitCommand, gitAddArgument );
Process.Start(gitCommand, gitCommitArgument );
Process.Start(gitCommand, gitPushArgument );

您可以包含您的证书,更多详细信息请参阅 Run git commands from a C# function

另一种方法是使用PowerShell脚本运行git命令并调用tfs api。

有一种方法可以使用当前可访问的API来实现它——获取提交时间,然后检查在该时间间隔内此类提交是否在分支中,尽管它需要两个单独的调用,并且可能有一些 问题 用:

1. Committer date vs Author date -我使用的是提交日期,但没有花足够的时间来真正检查它。

用法是:

GitHttpClient git = ...;
var isInBranch = git.BranchContains(
    project: "project",
    repositoryId: "repository",
    branch: "master",
    commitId: "12345678910...")

代码是:

public static class GitHttpClientExt
{
    /// <summary>
    /// Gets a value indicating whether a branch with name <paramref name="branch"/> (like 'master', 'dev') contains the commit with specified <paramref name="commitId"/>.
    /// Just like the <code>git branch --contains</code> it doesn't take possible reversions into account.
    /// </summary>
    public static Boolean BranchContains(this GitHttpClient git, String project, String repositoryId, String branch, String commitId)
    {
        var commitToFind = git.TryGetCommit(project: project, repositoryId: repositoryId, commitId: commitId);
        if (commitToFind == null)
        {
            return false;
        }
        var committedDate = commitToFind.Committer.Date; // TODO: It will usually be the same as the author's, but I have failed to check what date TFS actually uses in date queries.
        var criteria = new GitQueryCommitsCriteria
        {
            ItemVersion = new GitVersionDescriptor
            {
                Version = branch,
                VersionType = GitVersionType.Branch
            },
            FromDate = DateToString(committedDate.AddSeconds(-1)), // Zero length interval seems to work, but just in case
            ToDate = DateToString(committedDate.AddSeconds(1)),
        };
        var commitIds = git
            .GetAllCommits(
                project: project, 
                repositoryId: repositoryId,
                searchCriteria: criteria)
            .Select(c => c.CommitId);
        return commitIds.Contains(commitId);
    }

    /// <summary>
    /// Gets the string representation of <paramref name="dateTime"/> usable in query objects for <see cref="GitHttpClient"/>.
    /// </summary>
    public static String DateToString(DateTimeOffset dateTime)
    {
        return dateTime.ToString(CultureInfo.InvariantCulture);
    }

    /// <summary>Tries to retrieve git commit with specified <paramref name="commitId"/> for a project.</summary>
    public static GitCommitRef TryGetCommit(this GitHttpClient git, String project, String repositoryId, String commitId)
    {
        return git
            .GetAllCommits(
                project: project,
                repositoryId: repositoryId,
                searchCriteria: new GitQueryCommitsCriteria
                {
                    Ids = new List<String>
                    {
                        commitId
                    }
                })
            .SingleOrDefault();
    }

    /// <summary>Retrieve all(up to <see cref="Int32.MaxValue"/>) git (unless <paramref name="top"/> is set) commits for a project</summary>
    public static List<GitCommitRef> GetAllCommits(
        this GitHttpClient git, 
        String project,
        String repositoryId, 
        GitQueryCommitsCriteria searchCriteria, 
        Int32? skip = null, 
        Int32? top = (Int32.MaxValue - 1)) // Current API somehow fails (silently!) on Int32.MaxValue;
    {
        return git
            .GetCommitsAsync(
                project: project,
                repositoryId: repositoryId,
                searchCriteria: searchCriteria,
                skip: skip,
                top: top)
            .GetAwaiter()
            .GetResult();
    }
}

附笔。: 还有一种方法可以做到这一点 GetBranchStatsBatchAsync 更可靠的是,在某些情况下,API在范围内找不到特定的提交,错误地声明提交不在分支中(然后,我们用getBranchStatsBatchAsync替换了逻辑,此后没有问题)。

附笔。: 代码当前是异步方法上的同步包装器,因为这是当前项目中不幸需要的。如果适合的话,把它重新编写成适当的异步版本。
