Perforce Api - 如何命令“获取修订 [更改列表编号]”

Question

我想使用 Perforce .NET API (C#) 实现 Perforce 命令“Get Revision [Changelist Number]”。我目前有“获取最新版本”的代码，但我需要对其进行修改以获取特定的更改列表。

要将数据与变更列表编号同步，我应该怎么做？

// --------Connenct----------------
Perforce.P4.Server server = new Perforce.P4.Server(
    new Perforce.P4.ServerAddress("127.0.0.1:9999"));
Perforce.P4.Repository rep = new Perforce.P4.Repository(server);
Perforce.P4.Connection con = rep.Connection;

con.UserName = m_P4ID;
string password = m_P4PASS;

Perforce.P4.Options opconnect = new Perforce.P4.Options();
opconnect.Add("-p", password);
con.Connect(opconnect);

if (con.Credential == null)
    con.Login(password);

//----------Download----------
string clientPath = @"C:\P4V\";
string ws_client = clientPath;
Perforce.P4.Client client = new Perforce.P4.Client();
client.Name = ws_client;
client.Initialize(con);

con.CommandTimeout = new TimeSpan(0);
IList<Perforce.P4.FileSpec> fileList = client.SyncFiles(new Perforce.P4.Options());

//----------Disconnect------------
con.Disconnect();
con.Dispose();

编辑：尝试 1

Perforce.P4.DepotPath depot = new Perforce.P4.DepotPath("//P4V//");
Perforce.P4.LocalPath local = new Perforce.P4.LocalPath(ws_client);
Perforce.P4.FileSpec fs = new Perforce.P4.FileSpec(depot, null, local,
    Perforce.P4.VersionSpec.Head);

IList<Perforce.P4.FileSpec> listFiles = new List<Perforce.P4.FileSpec>();
listFiles.Add(fs);
IList<Perforce.P4.FileSpec> foundFiles = rep.GetDepotFiles(listFiles,
    new Perforce.P4.Options(1234)); // 1234 = Changelist number

client.SyncFiles(foundFiles, null);

错误信息

用法：文件/打印 [-o localFile -q] 文件...无效选项：-c.

我不知道任何论点的问题。

或者不会有相关的参考来源？

我试图解决这个问题。但是，它还没有解决问题。

Perforce.P4.Changelist changelist = rep.GetChangelist(1234);
IList<Perforce.P4.FileMetaData> fileMeta = changelist.Files;

在这种情况下，我只能获取更改列表中的文件。我想在changelist 1234的那一刻同步客户端的所有文件。

Answer 1

SyncFiles 采用可选的 FileSpec 参数。您可以使用该 FileSpec arg 指定文件路径和修订说明符。以下是相关文档：

FileSpec object docs

SyncFiles method docs

您无需运行 GetDepotFiles() 即可获取 FileSpec 对象；您可以直接创建一个，如 FileSpec 对象文档中所示。 GetDepotFiles() 出现的错误是因为它希望将更改编号指定为 FileSpec 对象的一部分，作为 GetDepotFiles() 的第一个参数传入。

为了进一步扩展，GetDepotFiles() 在与 Perforce 对话时调用“p4 文件”命令。 new Perforce.P4.Options(1234) 生成一个“-c 1234”选项，“p4 文件”不接受该选项。这就是为什么错误消息是'Usage: files/print [-o localFile -q] files...Invalid option: -c.'

我也遇到了同样的问题。最后根据马特的回答，我得到了它的工作。请看下面的简单示例。

        using (Connection con = rep.Connection)
        {
            //setting up client object with viewmap
            Client client = new Client();
            client.Name = "p4apinet_solution_builder_sample_application_client";
            client.OwnerName = "p4username";
            client.Root = "c:\\clientRootPath";
            client.Options = ClientOption.AllWrite;
            client.LineEnd = LineEnd.Local;
            client.SubmitOptions = new ClientSubmitOptions(false, SubmitType.RevertUnchanged);
            client.ViewMap = new ViewMap();
            client.ViewMap.Add("//depotpath/to/your/file.txt", "//" + client.Name + "/clientpath/to/your/file.txt", MapType.Include);

            //connecting to p4 and creating client on p4 server
            Options options = new Options();
            options["Password"] = "p4password";
            con.UserName = "p4username";
            con.Client = new Client();
            con.Connect(options);
            con.Client = rep.CreateClient(client);

            //syncing all files (in this case 1) defined in client's viewmap to the changelist level of 12345
            Options syncFlags = new Options(SyncFilesCmdFlags.Force, 100);
            VersionSpec changeListLevel = new ChangelistIdVersion(12345);
            List<FileSpec> filesToBeSynced = con.Client.ViewMap.Select<MapEntry, FileSpec>(me => new FileSpec(me.Left, changeListLevel)).ToList();
            IList<FileSpec> results = con.Client.SyncFiles(filesToBeSynced, syncFlags);
        }

以下代码应允许您将软件仓库同步到特定修订版（更改列表编号）。

string uri = "...";
string user = "...";
string workspace = "...";
string pass = "..."; 
int id = 12345; // the actual changelist number
string depotPath = "//depot/foo/main/...";
int maxItemsToSync = 10000;

Server server = new Server(new ServerAddress(uri));
Repository rep = new Repository(server);

server = new Server(new ServerAddress(uri));
rep = new Repository(server);
Connection con = rep.Connection;
con.UserName = user;
con.Client = new Client();
con.Client.Name = workspace;

// connect
bool connected = con.Connect(null);
if (connected)
{
    try
    {
        // attempt a login
        Perforce.P4.Credential cred = con.Login(pass);
    }
    catch (Exception ex)
    {
        Console.WriteLine(ex.Message);
        con.Disconnect();
        connected = false;
    }

    if (connected)
    {
        // get p4 info and show successful connection
        ServerMetaData info = rep.GetServerMetaData(null);
        Console.WriteLine("CONNECTED TO " + info.Address.Uri);
        Console.WriteLine("");

        try
        {
            Options opts = new Options();

            // uncomment below lines to only get a preview of the sync w/o updating the workspace
            //SyncFilesCmdOptions syncOpts = new SyncFilesCmdOptions(SyncFilesCmdFlags.Preview, maxItemsToSync);
            SyncFilesCmdOptions syncOpts = new SyncFilesCmdOptions(SyncFilesCmdFlags.None, maxItemsToSync);

            VersionSpec version = new ChangelistIdVersion(id);
            PathSpec path = new DepotPath(depotPath);
            FileSpec depotFile = new FileSpec(path, version);

            IList<FileSpec> syncedFiles = rep.Connection.Client.SyncFiles(syncOpts, depotFile);
            //foreach (var file in syncedFiles)
            //{
            //    Console.WriteLine(file.ToString());
            //}
            Console.WriteLine($"{syncedFiles.Count} files got synced!");
        }
        catch (Exception ex)
        {
            Console.WriteLine("");
            Console.WriteLine(ex.Message);
            Console.WriteLine("");
        }
        finally
        {
            con.Disconnect();
        }
    }
}
