> Bogus END_OF_FILE exception

> Key: THRIFT-5492
> URL: https://issues.apache.org/jira/browse/THRIFT-5492
> Project: Thrift
> Issue Type: Bug
> Components: C++ - Library
> Affects Versions: 0.14.1
> Reporter: Steven Licking

> When using a TMultiplexedProcessor server with TBufferedTransportFactory and
> TBinaryProtocolFactory a connection to a client will be closed due to an
> END_OF_FILE exception after sending many messages.
> It appears that when the client connects, in class TTransport, the
> remainingMessageSize_ is set to getMaxMessageSize() which, by default, is
> DEFAULT_MAX_MESSAGE_SIZE and is defined to be 100*1024*1024 in
> TConfiguration.h.
> The remainingMessageSize_ is decremented as messages are parsed, for example
> when parsing a field in the message that is of type binary I see the code
> calling readStringBody in TBinaryProtocol.tcc:455 which then calls
> this->trans_->consume(size) which goes to TBufferTransports.h:124 and calls
> countConsumedMessageBytes which finally decrements remainingMessageSize_.
> However, nothing ever resets remainingMessageSize_, so after it is
> decremented from 100*1024*1024 down to zero it fails with an END_OF_FILE
> exception.
> It seems that the remainingMessageSize_ should be reset either when a new
> message is received from the client or after a message is processed. However
> I'm not quite sure what the intended purpose of remainingMessageSize_ is.
