使用 QueryBuilds 从 TFS 查询构建的性能非常低

Question

我正在尝试访问具有“无限期保留”标志（BuildDetail.KeepForever 属性）的本地 TFS 2015 服务器中的每个构建，但 QueryBuilds() 函数需要太长时间才能获取所有构建。

TFS 2015 'Retain Indefinitely' Web GUI Menu Option

我真正需要的是KeepForever 和DropLocation 属性。

我发现使用IBuildDetailSpec 接口可以提高效率，但我找不到可以获取KeepForever 属性的选项。

我当前的代码sn-p：

public void BackupOnlyRetainedBuilds(string TeamProjectName, string DestinationPath)
{
    defs[...]

    Uri configurationServerUri = new Uri("http://builder:8080/tfs");
    TfsTeamProjectCollection server = new TfsTeamProjectCollection(configurationServerUri);

    //get builds server
    buildServer = (IBuildServer)server.GetService(typeof(IBuildServer));

    //set up an array of all build definition from a spcific team project.
    IBuildDefinition[] bda = buildServer.QueryBuildDefinitions(TeamProjectName);

    //check each build definition.
    foreach (var buildDefinition in bda)
    {
        //set an array of builds history.
        IBuildDetail[] bha = buildDefinition.QueryBuilds();

        //check each build from build history build details.
        foreach (var buildDetails in bha)
        {
            //check if build is retained.
            if (buildDetails.KeepForever == true)
            {
                string dropLocationPath = buildDetails.DropLocation;

                //check if drop folder exists.
                if (Directory.Exists(dropLocationPath))
                {
                    //create all of the directories.
                    foreach (string dirPath in Directory.GetDirectories(dropLocationPath, "*",
                        SearchOption.AllDirectories))
                        Directory.CreateDirectory(dirPath.Replace(dropLocationPath, DestinationPath));

                    //copy all the files & Replaces any files with the same name.
                    foreach (string newPath in Directory.GetFiles(dropLocationPath, "*.*",
                        SearchOption.AllDirectories))
                        File.Copy(newPath, newPath.Replace(dropLocationPath, DestinationPath), true);
                }
            }
        }
    }
}

你可以告诉QueryBuilds不要从我的tfsbuild.exe的补丁版本中获取所有构建细节，而只获取你感兴趣的那些：

buildDetailSpec = this.BuildServer.CreateBuildDetailSpec(...)
buildDetailSpec.QueryDeletedOption = !forDestroy ? QueryDeletedOption.IncludeDeleted : QueryDeletedOption.OnlyDeleted;
buildDetailSpec.InformationTypes = null;
IBuildQueryResult buildQueryResult = this.BuildServer.QueryBuilds(buildDetailSpec);

或者也可以使用QueryBuildsUri 并通过(string[]) null, QueryOptions.None：

IBuildDetail[] buildDetailArray = this.BuildServer.QueryBuildsByUri(list2.ToArray(), (string[]) null, QueryOptions.None, QueryDeletedOption.IncludeDeleted);

您可能需要将一组特定的InformationTypes 传递给它，具体取决于您作为备份工具的一部分所需的数据。
