TFramedTransport打开时，节点中的TNonblockingServer崩溃 [英] TNonblockingServer in thrift crashes when TFramedTransport opens

问题描述

我一直在尝试在C ++中实现一个thrift服务器来与Python客户端通信。

这里是我的代码：

C ++服务器：

  shared_ptr< ThriftHandler> _handler（new myHandler（））; 
 shared_ptr< TProcessor> _processor（new myService（_handler））; 
 shared_ptr< TProtocolFactory> _protocolFactory（new TBinaryProtocolFactory（））; 
 shared_ptr< ThreadManager> _threadManager = ThreadManager :: newSimpleThreadManager（15）; 
 shared_ptr< PosixThreadFactory> _threadFactory（new PosixThreadFactory（））; 
 _threadManager-> threadFactory（_threadFactory）; 
 _threadManager-> start（）; 
 
 shared_ptr< TNonblockingServer> _server（new TNonblockingServer（_processor，_protocolFactory，9090，_threadManager））;; 
 _server-> serve（）; 
  

Python客户端代码：

  transport = TSocket.TSocket（host，port）
 transport = TTransport.TFramedTransport（transport）
 protocol = TBinaryProtocol.TBinaryProtocol（transport）
 client = MyService.Client （协议）
 transport.open（）
 log.info（连接成功！）
  

当我启动服务器，然后客户端，我得到以下：

在客户端（Python）：

  ./ myPythonExec.py 
连接成功！ 
 socket.error：[Errno 104]由对等连接重置
  

在服务器端c ++）：

我使用libthrift 0.8.0和libthrift 0.9.1的相同的pb

它使用TSimpleServer on C ++和TBufferedTransport在客户端

解决方案

对不起，前面没有看到，但看起来像同样的问题：
使用Apache Thrift的服务多路复用

  shared_ptr< TTransportFactory> ; _transportFactory（new TFramedTransportFactory（））; 
 shared_ptr< TNonblockingServer> _server（
 new TNonblockingServer（
 _processor，
 _transportFactory，
 _transportFactory，
 _protocolFactory，
 _protocolFactory，
 9090，
 _threadManager ））; 
 _server-> serve（）; 
  

I've been trying to implement a thrift server in C++ to communicate with a Python client.

here is my code:

C++ server:

shared_ptr<ThriftHandler> _handler (new myHandler());
shared_ptr<TProcessor> _processor (new myService(_handler));
shared_ptr<TProtocolFactory> _protocolFactory (new TBinaryProtocolFactory());
shared_ptr<ThreadManager> _threadManager = ThreadManager::newSimpleThreadManager(15);
shared_ptr<PosixThreadFactory> _threadFactory(new PosixThreadFactory());
_threadManager->threadFactory(_threadFactory);
_threadManager->start();

shared_ptr<TNonblockingServer> _server(new TNonblockingServer(_processor, _protocolFactory, 9090 ,_threadManager));;
_server->serve();

Python Client code:

transport = TSocket.TSocket(host, port)
transport = TTransport.TFramedTransport(transport)
protocol = TBinaryProtocol.TBinaryProtocol(transport)
client = MyService.Client(protocol)
transport.open()
log.info("connection success!")

When I start the server and then the client, I get the following:

On the client side (Python):

./myPythonExec.py
connection success!
socket.error: [Errno 104] Connection reset by peer

On the server side (c++):

assertion " 0 " failed
0  0x00007ffff0942425 in __GI_raise (sig=<optimized out>) at ../nptl/sysdeps/unix/sysv/linux/raise.c:64
1  0x00007ffff0945b8b in __GI_abort () at abort.c:91
2  0x00007ffff093b0ee in __assert_fail_base (fmt=<optimized out>, assertion=0x7ffff1438f1a "0",

3  0x00007ffff093b192 in __GI___assert_fail (assertion=0x7ffff1438f1a "0", file=0x7ffff1439298 "src/server/TNonblockingServer.cpp", 
line=558, function=0x7ffff1439c60 "void apache::thrift::server::TNonblockingServer::TConnection::workSocket()") at assert.c:103
4  0x00007ffff14336e4 in apache::thrift::server::TNonblockingServer::TConnection::workSocket (this=0x7fffc0004ac0)
at src/server/TNonblockingServer.cpp:558
5  0x00007ffff11ed94c in event_base_loop () from /usr/lib/libevent-2.0.so.5

I'm using libthrift 0.8.0 and have the same pb with libthrift 0.9.1

It works perfectly when using a TSimpleServer on C++ and a TBufferedTransport on the client side

解决方案

Sorry, have not seen earlier, but looks like the same issue: Service Multiplexing using Apache Thrift

In short, you have to use either framed on both sides, or none.

shared_ptr<TTransportFactory> _transportFactory(new TFramedTransportFactory());
shared_ptr<TNonblockingServer> _server(
   new TNonblockingServer(
     _processor, 
     _transportFactory,
     _transportFactory,
     _protocolFactory, 
     _protocolFactory, 
     9090,
     _threadManager));
_server->serve();
