2012-06-13Revert "Implement SP wire protocol"Martin Sustrik
This reverts commit a34ea4d80609395150742259fd8c9caa4409e961.
2012-05-25Implement SP wire protocolMartin Lucina
Implements the SP wire protocol, and infrastructure for legacy wire protocol support. Also added an XS_SERVICE_ID socket option to set the service id and renamed the XS_PROTOCOL option to XS_PATTERN_VERSION. The following pattern versions are supported: PAIR: v3 PUBSUB: v1 (legacy), v4 REQREP: v2 PIPELINE: v3 SURVEY: v2 Note that all existing pattern versions have been bumped by 1 to allow for use of legacy protocols (otherwise there would be no way to distinguish between e.g. PUBSUB v3 and PUBSUB v3 using SP).

2012-04-29Implement protocol versioning (except PGM)Martin Lucina
Implements SP protocol versioning, legacy protocol support, and the following pattern protocol versions: PAIR: v2 PUBSUB: v1 (legacy), v3 REQREP: v1 PIPELINE: v2 SURVEY: v1 Engine support is only for stream_engine_t at this stage. Signed-off-by: Martin Lucina <martin@lucina.net>
2012-04-06Allow pipe_t::flush() to be called from pipe_t::terminate()Martin Sustrik
Previous patch have broken flushing a delimiter in pipe_t::terminate() function. This patch allows the flush to happen even if pipe state is set to 'terminated'. Signed-off-by: Martin Sustrik <sustrik@250bpm.com>
2012-04-06Fix bogus typo in xs::pipe_t::flush()Andrew W. Nosenko
* src/pipe.cpp (flush): Fix bogus typo: '&&' was used instead of '||'

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>
2011-06-20LABEL 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>

2011-05-25All pipe termination code moved to pipe_tMartin Sustrik
Till now the code was spread over mutliple locations. Additionally, the code was made more formally correct, with explicit pipe state machine etc. 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.

2011-03-24SWAP functionality removedMartin Sustrik
On-disk storage should be implemented in devices rather than in 0MQ core. 0MQ is a networking library and there's no point in storing network buffers on disk. 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.

2010-06-17pipe: fix bug in rollback() methodMartin Hurton
The msgs_written variable keeps track how many complete messages have been written so far. The rollback operation drops all fragments of the last incomplete message so it shouldn't change this variable at all.
