2011-10-29Corrected discarding of remainder of message when request ID invalidPerry Kundert
When zmq::req_t::xrecv detects that a response has no request ID label, or the ID is the wrong size, it would return an EAGAIN, but would not discard the remainder of the message. This could allow the remainder of the message to incorrectly "leak" into a future response, if it is crafted to look like a reply with a valid response ID. Discard all remaining message blocks, if the ID is invalid in any way.
2011-09-16Check message syntax in REQ asynchronouslyMartin Sustrik
This patch adds support for checking messages as they arrive (as opposed to when they are recv'd by the user) and drop the connection if they are malformed. It also uses this new feature to check for validity of inbound messages in REQ socket. Signed-off-by: Martin Sustrik <sustrik@250bpm.com>
2011-09-15Session class separated into socket-type-specific sessionsMartin Sustrik
This is a preliminary patch allowing for socket-type-specific functionality in the I/O thread. For example, message format can be checked asynchronously and misbehaved connections dropped straight away. Signed-off-by: Martin Sustrik <sustrik@250bpm.com>

2011-06-22New wire format for REQ/REP patternMartin Sustrik
This patch introduces two changes: 1. 32-bit ID is used to identify the peer instead of UUID 2. REQ socket seeds the label stack with unique 32-bit request ID It also drops any replies with non-matching request ID Signed-off-by: Martin Sustrik <sustrik@250bpm.com>
2011-06-20LABEL flag added to the wire formatMartin Sustrik
So far there was no distinction between message parts used by 0MQ and message parts used by user. Now, the message parts used by 0MQ are marked as 'LABEL'. Signed-off-by: Martin Sustrik <sustrik@250bpm.com>
2011-04-21Message-related functionality factored out into msg_t class.Martin Sustrik
This patch addresses serveral issues: 1. It gathers message related functionality scattered over whole codebase into a single class. 2. It makes zmq_msg_t an opaque datatype. Internals of the class don't pollute zmq.h header file. 3. zmq_msg_t size decreases from 48 to 32 bytes. That saves ~33% of memory in scenarios with large amount of small messages.

2010-11-05slots renamed to tidsMartin Sustrik
Threads were so far identified by integers called 'slots'. This patch renames them to more comprehensible 'tid's (thread IDs). Signed-off-by: Martin Sustrik <sustrik@250bpm.com>

2010-08-25WIP: Socket migration between threads, new zmq_close() semanticsMartin Sustrik
Sockets may now be migrated between OS threads; sockets may not be used by more than one thread at any time. To migrate a socket to another thread the caller must ensure that a full memory barrier is called before using the socket from the target thread. The new zmq_close() semantics implement the behaviour discussed at: http://lists.zeromq.org/pipermail/zeromq-dev/2010-July/004244.html Specifically, zmq_close() is now deterministic and while it still returns immediately, it does not discard any data that may still be queued for sending. Further, zmq_term() will now block until all outstanding data has been sent. TODO: Many bugs have been introduced, needs testing. Further, SO_LINGER or an equivalent mechanism (possibly a configurable timeout to zmq_term()) needs to be implemented.

2010-03-12Implement flow controlMartin Hurton
This commit introduces the necessary changes necessary for implementing flow control. None of the socket types implements the flow control yet. The code will crash when the flow control is enabled and the thw lwm is reached. The following commits will add flow-control support for individual socket types.
