James E. King III commented on THRIFT-4890:
-------------------------------------------
Sounds like there's a buffer or position management error in the non-blocking
server when dealing with large data sets.
> AttributeError: 'Connection' object has no attribute 'message'

> Key: THRIFT-4890
> URL: https://issues.apache.org/jira/browse/THRIFT-4890
> Project: Thrift
> Issue Type: Bug
> Components: Python - Compiler
> Affects Versions: 0.12.0
> Environment: Ubuntu Linux 18.10 64-bit
> Reporter: Giorgi Grigalashvili
> Priority: Major
> Labels: Connection, Newbie, Python3, Question
>
> As part of my university research I'm using Thrift v0.12.0 to communicate
> between Python server and Scala client.
> The data my service is providing to client is lists of thrift
> objects/structs, those lists contain ~1M items. The issue bellow is produced
> if I'm sending full lists(more than ~60k items) of data, however if I
> decrease list items to ~60k everything works fine.
> {code:java}
> Traceback (most recent call last):
> File "Server.py", line 40, in <module>
> server.serve()
> File "thrift/server/TNonblockingServer.py", line 370, in serve
> self.handle()
> File "thrift/server/TNonblockingServer.py", line 350, in handle
> self.clients[writeable].write()
> File "thrift/server/TNonblockingServer.py", line 88, in read
> return func(self, *args, **kwargs)
> File "thrift/server/TNonblockingServer.py", line 177, in write
> self._wbuf = self.message[sent:]
> AttributeError: 'Connection' object has no attribute 'message'
> {code}
> This is my server configuration:
> {code:java}
> ip = '127.0.0.1'
> port = '9000'
> handler = MyHandler()
> processor = MyService.Processor(handler)
> transport = TSocket.TServerSocket(host=ip, port=port)
> tfactory = TBinaryProtocol.TBinaryProtocolFactory()
> pfactory = TBinaryProtocol.TBinaryProtocolFactory()
> server = TNonblockingServer.TNonblockingServer(processor, transport,
> tfactory, pfactory)
> server.serve()
> {code}
> Now my question is as follows, am I doing something wrong or could it be that
> it's an issue from Thrift? Any ideas how can I resolve this problem or what I
> could be doing wrong?
> Thanks in advance.
