Gradle P4Java java.net.SocketTimeoutException:读取超时

Question

我在build.gradle文件中使用build.gradle库来同步驻留在远程Perforce存储库中的大型zip文件(>200 my )，但在同步过程中或在删除为同步操作创建的临时客户端期间(大多数情况下)，我遇到了"java.net.SocketTimeoutException: Read“错误。我指的是使用http://razgulyaev.blogspot.in/2011/08/p4-java-api-how-to-work-with-temporary.html API处理临时客户端的P4Java。

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，并引入睡眠，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，探查服务器以使用getServerInfo()验证连接将导致成功的连接检查。有人能指点我到哪里去找答案吗？

谢谢。

提供代码片段：

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时观察到的一件不寻常的事情是，它实际上删除了客户机，但仍然抛出"java.net.SocketTimeoutException: Read“，这就是为什么我最后在第二个catch块中注释了第二个delete尝试。

您使用的是哪个版本的P4Java？你用最新的P4Java试过这个吗？自2013.2版本转发以来，有一些处理RPC套接字的值得注意的修补程序，如发行说明所示：

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

这里有一些变体，您可以在有代码的地方尝试这些变体来增加超时和实例化服务器：

你有没有试过在它自己的论点中传递道具？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);

或者类似于以下几点：

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

您还可以将超时设置为"0“，以使其不超时。

(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P4Eclipse用户使用我们的P4Java插件，则可以在自定义P4Java属性下的插件首选项(Team->Perforce->Advanced)中设置该属性。

sockSoTimeout："3000000“
