2012-02-16poller_base_t renamed to io_thread_tMartin Sustrik
Signed-off-by: Martin Sustrik <sustrik@250bpm.com>
2012-02-16io_thread_t merged with poller_base_tMartin Sustrik
The relationship of these two classes was 1:1. Thus one of them was obsolete. Signed-off-by: Martin Sustrik <sustrik@250bpm.com>
2012-02-16Fix data loss for PUB/SUB and unidirectional transports (LIBZMQ-268)Martin Lucina
With the introduction of subscription forwarding, the first message sent on a PUB socket using a unidirectional transport (e.g. PGM) is always lost due to the "subscribe to all" being done asynchronously. This patch fixes the problem and also refactors the code to have a single point where the "subscribe to all" is performed. Signed-off-by: Martin Lucina <martin@lucina.net>

2011-12-17Fix polling on XREP socketMartin Sustrik
When polling on XREP socket in incoming message part was prefetched, but not the identity of sender. The problem is fixed by this patch. Signed-off-by: Martin Sustrik <sustrik@250bpm.com>
2011-11-09Get AIX 6.1 compiling again by making msg_t class explicitAJ Lewis
Older versions of gcc have problems with in-line forward declarations when there's a naming conflict with a global symbol. Signed-off-by: AJ Lewis <aj.lewis@quantum.com> Expand the original patch to all such forward declarations. Signed-off-by: Martin Sustrik <sustrik@250bpm.com>
2011-11-04Identities re-introducedMartin Sustrik
However, the "durable socket" behaviour wasn't re-added. Identities are used solely for routing in REQ/REP pattern. 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>
2011-07-15ZMQ_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>
2011-06-22O(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>
2011-05-23Move 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>

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>
2010-10-08Clean-up of session termination processMartin Sustrik
Specifically, shutdown of child objects is initiated *before* termination handshake with socket object. 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.
