Gradle P4Java java.net.SocketTimeoutException: Read timed ou

Question

我在构建中使用P4Java库。gradle文件同步一个大的zip文件(>200MB)驻留在远程Perforce存储库，但我遇到了一个"java.net.SocketTimeoutException:读取超时"错误，无论是在同步过程中或(大部分)在删除为同步操作创建的临时客户端。我参考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。

我尝试增加套接字读取超时从默认的30秒建议http://answers.perforce.com/articles/KB/8044，也通过引入睡眠，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，使用getServerInfo()探测服务器以验证连接，将导致连接检查成功。谁能告诉我应该去哪里找答案?

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时观察到的一个不寻常的事情是，它实际上删除了客户端，但仍然抛出"java.net.SocketTimeoutException: Read timed out"，这就是为什么我最终在第二个catch块中注释了第二次删除尝试。

您使用的是哪个版本的P4Java ?您在最新的P4Java上尝试过这个功能吗?自2013.2版本以来，有一些处理RPC套接字的显著修复，可以在发行说明中看到:

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

这里有一些变化，你可以尝试在你的代码中增加超时和实例化服务器:

a]是否尝试在自己的参数中传递props ?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);

或者像下面这样:

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

您也可以将超时时间设置为"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]如果您有Eclipse用户使用我们的P4Eclipse插件，该属性可以在自定义P4Java属性下的插件首选项(Team->Perforce->Advanced)中设置。

"sockSoTimeout": "3000000"
