Resolution: Duplicate
> concurent client calls with nodejs
> ----------------------------------
>
> Key: THRIFT-2306
> URL: https://issues.apache.org/jira/browse/THRIFT-2306
> Project: Thrift
> Issue Type: Bug
> Components: Node.js - Library
> Affects Versions: 0.9.1
> Reporter: Pierre Lamot
>
> hello,
> I think there is a bug in nodejs client library when making concurent calls
> my idl is:
> {code}
> struct Card {
> 1: required i32 id,
> 2: optional string name,
> }
> struct Player {
> 1: string name,
> 2: i32 actions,
> 3: i32 treasures,
> 4: i32 buys
> }
> typedef list<Card> Cardlist
> union ChooseReply {
> 1: Cardlist cards,
> 2: string special
> }
> struct ChooseOpt {
> 1: optional string msg,
> 2: optional Cardlist cards,
> 3: optional i32 nbcard,
> 4: optional string nbqualifier,
> 5: optional list<string> special
> }
> service Client {
> void showPlayerStatus(1: Player player),
> ChooseReply choose(1: ChooseOpt opt),
> }
> {code}
> for the server part:
> {code}
> from thrift.transport import TSocket
> from thrift.transport import TTransport
> from thrift.protocol import TBinaryProtocol
> from thrift.protocol import TJSONProtocol
> from thrift.server import TServer
> from client import Client
> from client.ttypes import *
> class ClientStub(object):
> def showPlayerStatus(self, player):
> print "showPlayerStatus called"
> print player
> def choose(self, opt):
> print "choose called"
> print opt
> if opt.cards and len(opt.cards) > 0:
> ret = ChooseReply(cards = opt.cards[-1:])
> elif opt.special and len(opt.special) > 0:
> ret = ChooseReply(special = opt.special[-1])
> print ret
> return ret
> def main():
> handler = ClientStub()
> processor = Client.Processor(handler)
> transport = TSocket.TServerSocket(port = 9090)
> tfactory = TTransport.TBufferedTransportFactory()
> #pfactory = TJSONProtocol.TJSONProtocolFactory()
> pfactory = TBinaryProtocol.TBinaryProtocolFactory()
> server = TServer.TSimpleServer(processor, transport, tfactory, pfactory)
> server.serve()
> if __name__ == "__main__":
> main()
> {code}
> and the client
> {code}
> "use strict";
