Question

我在build.gradle文件中使用P4Java库来同步驻留在远程Perforce存储库中的大型zip文件（> 200MB），但是我遇到了“java.net.SocketTimeoutException：Read timed out”错误同步过程或（主要）在删除为同步操作创建的临时客户端期间。我指的是http://razgulyaev.blogspot.in/2011/08/p4-java-api-how-to-work-with-temporary.html使用P4Java API处理临时客户端。

我尝试按照http://answers.perforce.com/articles/KB/8044中的建议从默认的30秒增加套接字读取超时，并且还引入了睡眠，但这两种方法都没有解决问题。在执行同步或删除操作之前，探测服务器使用getServerInfo（）验证连接会导致连接检查成功。有人可以指点我应该在哪里寻找答案吗？

谢谢。

提供代码段：

void perforceSync(String srcPath, String destPath, String server) {

    // Generating the file(s) to sync-up
    String[] pathUnderDepot = [
            srcPath + "*"
        ]

    // Increasing timeout from default 30 sec to 60 sec
    Properties defaultProps = new Properties()
    defaultProps.put(PropertyDefs.PROG_NAME_KEY, "CustomBuildApp")
    defaultProps.put(PropertyDefs.PROG_VERSION_KEY, "tv_1.0")
    defaultProps.put(RpcPropertyDefs.RPC_SOCKET_SO_TIMEOUT_NICK, "60000")

    // Instantiating the server
    IOptionsServer p4Server = ServerFactory.getOptionsServer("p4java://" + server, defaultProps)
    p4Server.connect()

    // Authorizing
    p4Server.setUserName("perforceUserName")
    p4Server.login("perforcePassword")

    // Just check if connected successfully
    IServerInfo serverInfo = p4Server.getServerInfo()
    println 'Server info: ' + serverInfo.getServerLicense()

    // Creating new client
    IClient tempClient = new Client()

    // Setting up the name and the root folder
    tempClient.setName("tempClient" + UUID.randomUUID().toString().replace("-", ""))
    tempClient.setRoot(destPath)
    tempClient.setServer(p4Server)

    // Setting the client as the current one for the server
    p4Server.setCurrentClient(tempClient)

    // Creating Client View entry
    ClientViewMapping tempMappingEntry = new ClientViewMapping()

    // Setting up the mapping properties
    tempMappingEntry.setLeft(srcPath + "...")
    tempMappingEntry.setRight("//" + tempClient.getName() + "/...")
    tempMappingEntry.setType(EntryType.INCLUDE)

    // Creating Client view
    ClientView tempClientView = new ClientView()

    // Attaching client view entry to client view
    tempClientView.addEntry(tempMappingEntry)
    tempClient.setClientView(tempClientView)

    // Registering the new client on the server
    println p4Server.createClient(tempClient)

    // Surrounding the underlying block with try as we want some action
    // (namely client removing) to be performed in any way
    try {

        // Forming the FileSpec collection to be synced-up
        List<IFileSpec> fileSpecsSet = FileSpecBuilder.makeFileSpecList(pathUnderDepot)

        // Syncing up the client
        println "Syncing..."
        tempClient.sync(FileSpecBuilder.getValidFileSpecs(fileSpecsSet), true, false, false, false)
    }
    catch (Exception e) {
        println "Sync failed.  Trying again..."
        sleep(60 * 1000)
        tempClient.sync(FileSpecBuilder.getValidFileSpecs(fileSpecsSet), true, false, false, false)
    }
    finally {
        println "Done syncing."

        try {
            p4Server.connect()

            IServerInfo serverInfo2 = p4Server.getServerInfo()
            println '\nServer info: ' + serverInfo2.getServerLicense()

            // Removing the temporary client from the server
            println p4Server.deleteClient(tempClient.getName(), false)
        }
        catch(Exception e) {
            println 'Ignoring exception caught while deleting tempClient!'

            /*sleep(60 * 1000)
            p4Server.connect()

            IServerInfo serverInfo3 = p4Server.getServerInfo()
            println '\nServer info: ' + serverInfo3.getServerLicense()

            sleep(60 * 1000)
            println p4Server.deleteClient(tempClient.getName(), false)*/
        }
    }
}

我在删除tempClient时观察到的一个不寻常的事情是它实际上是删除了客户端但仍然抛出“java.net.SocketTimeoutException：Read timed out”这就是为什么我最终评论第二个catch块中的第二次删除尝试。

您使用的是哪个版本的P4Java？你有没有尝试过最新的P4Java？自2013.2版以来，有很多处理RPC套接字的修复程序可以在发行说明中看到：

http://www.perforce.com/perforce/doc.current/user/p4javanotes.txt

以下是您可以尝试使用代码增加超时和实例化服务器的一些变体：

a]你试过在自己的论点中传递道具吗？例如：

  Properties prop = new Properties();
  prop.setProperty(RpcPropertyDefs.RPC_SOCKET_SO_TIMEOUT_NICK, "300000");
  UsageOptions uop = new UsageOptions(prop);
  server = ServerFactory.getOptionsServer(ServerFactory.DEFAULT_PROTOCOL_NAME + "://" + serverPort, prop, uop);

或类似以下内容：

  IOptionsServer p4Server = ServerFactory.getOptionsServer("p4java://" + server, defaultProps)

您也可以将超时设置为“0”，使其不会超时。

b]

   props.put(RpcPropertyDefs.RPC_SOCKET_SO_TIMEOUT_NICK, "60000");
   props.put(RpcPropertyDefs.RPC_SOCKET_POOL_SIZE_NICK, "5");

c]

Properties props = System.getProperties();
props.put(RpcPropertyDefs.RPC_SOCKET_SO_TIMEOUT_NICK, "60000");

IOptionsServer server =
ServerFactory.getOptionsServer("p4java://perforce:1666", props, null);

d]如果Eclipse用户使用我们的P4Eclipse插件，可以在Custom P4Java Properties下的插件首选项（Team-＆gt; Perforce-＆gt; Advanced）中设置该属性。

“sockSoTimeout”：“3000000”
