[boost] [asio] boost::asio::read with empty input vector leads to an infinite loop

12 Jul 2012


      Hello,
In the code bellow I have forgotten to set the input vector (request) size.
Is the code really supposed to react as an infinite loop (no errors, length
is always 0, boost::asio::read returns immediately) or such behavior is a
defect?

	for (;;) {
		std::vector<uint8_t> request;
		boost::system::error_code error;
		size_t length = boost::asio::read(sock,
boost::asio::buffer(request), error);
		if (error == boost::asio::error::eof)
			break;
		else if (error)
			throw my_exception(L"Socket error"); 
		...
	}

Thank you in advance,
