2011-07-15ZMQ_IDENTITY socket option removedMartin Sustrik
This patch simplifies the whole codebase significantly, including dropping depedency on libuuid. Signed-off-by: Martin Sustrik <sustrik@250bpm.com>

2011-06-23Outstanding requests dropped when requester dies (issue 190)Martin Sustrik
So far the requests in req/rep pattern were delivered to and processed by worker even though the original requester was dead. Thus, the worker processing replies with noone to deliver results to. This optimisation drops requests in two situations: 1. Queued inbound requests in XREP socket when peer disconnects. 2. Queued outbound requests in XREQ when socket is closed.

2011-06-22O(1) fair-queueing in XREP implementedMartin Sustrik
Up to now the complexity of fair-queueing in XREP was O(n). 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>
2011-05-23Move the pipe termination code to socket_base_tMartin Sustrik
So far, the pipe termination code was spread among socket type classes, fair queuer, load balancer, etc. This patch moves all the associated logic to a single place. Signed-off-by: Martin Sustrik <sustrik@250bpm.com>
2011-05-22Introduces bi-directional pipesMartin Sustrik
So far, there was a pair of unidirectional pipes between a socket and a session (or an inproc peer). This resulted in complex problems with half-closed states and tracking which inpipe corresponds to which outpipe. This patch doesn't add any functionality in itself, but is essential for further work on features like subscription forwarding. Signed-off-by: Martin Sustrik <sustrik@250bpm.com>

Moving the erase after the access and check agains current_id.
2011-05-02Current inpipe remains unchaged in XREP when other pipe terminatesMartin Sustrik
When an inpipe terminated within XREP, it was erased from the array and thus current_in (which is an index) pointed to a different element in the array. This caused problems when we were in the middle of reading a multipart message. 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>

2010-10-16ZMQ_LINGER socket option added.Martin Sustrik
1. ZMQ_LINGER option can be set/get 2. options are part of own_t base class rather than being declared separately by individual objects 3. Linger option is propagated with "term" command so that the newest value of it is used rather than the stored old one. 4. Session sets the linger timer if needed and terminates as soon as it expires. 5. Corresponding documentation updated. Signed-off-by: Martin Sustrik <sustrik@250bpm.com>

2010-10-11Reverting commit 1d431190f50c86f62460Martin Sustrik
The patch was supposed to check that pipe writer sends messages in atomic fashion. However, it prevented the user to read half of a message and close the socket. 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.
2010-08-1146 - Devices vulnerable to invalid messagesPieter Hintjens
http://github.com/zeromq/zeromq2/issues#issue/46 Invalid messages are now discarded silently, instead of causing an assertion failure.

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.
