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>
2012-04-27Truncate the message when it is sent to XSUBMartin Sustrik
This patch is based on patch by Martin Hurton from 0MQ project. Signed-off-by: Martin Sustrik <sustrik@250bpm.com>
2012-04-14Separate subscription forwarding from SUB-side filteringMartin Sustrik
- subscription forwarding is handled by XSUB socket - filtering is handled by SUB sockets - subscriptions are decoupled from filter engines - filter doesn't have to be able to enumarate the subscriptions (no sf_enumerate function) Signed-off-by: Martin Sustrik <sustrik@250bpm.com>
2012-04-05XS_PLUGIN and XS_FILTER implementationMartin Sustrik
This patch introduces following features: - XS_PLUGIN context option to add plugins to libxs - XS_FILTER option to switch between different filter types - Automatic loading of plug-ins is *not* implemented. From the implementation point of view: - standard prefix filter is implemented as a pluggable filter - trie_t and mtrie_t are joined into a single class - the code for 0MQ/3.1 compatibility is left in in the form of comments - new test for testing re-subscriptions is added Signed-off-by: Martin Sustrik <sustrik@250bpm.com>
2012-04-040MQ/2.1 wire format compatibility implementedMartin Sustrik
- XS_PROTOCOL option added - libxs ignores when unused flags are set to 1 (0MQ/2.1 bug) - compatibility tests added Signed-off-by: Martin Sustrik <sustrik@250bpm.com>
2012-02-17Drop subscription messages when reaching the SNDHWM rather than asserting.Staffan Gimåker
This matches the behaviour of zmq_setsockopt(ZMQ_SUBSCRIBE, ...), which also silently drops subscription messages if the SNDHWM is reached. Signed-off-by: Staffan Gimåker <staffan@spotify.com>

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>
2012-02-16Subscription buffer in XSUB socket made elasticMartin Sustrik

2011-12-17Dont wait for pending subscription commands on shutdownMartin Sustrik
When (X)SUB socket is being shut down there may be pending outbound subscription commands in the pipes. In such case we want to close the socket immediately instead of waiting for the commands to be sent. 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>
2011-09-01Premature deallocation bug in XSUB fixed (issue 244)Martin Sustrik
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>

2011-06-20LABEL 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>
2011-06-13Minor patch to fix ICC buildMartin Sustrik
Signed-off-by: Martin Sustrik <sustrik@250bpm.com>
2011-06-12ZMQ_FILTER socket option addedMartin Sustrik
This option is a performance tweak. In devices XSUB socket filters the messages just to send them to XPUB socket which filters them once more. Setting ZMQ_FILTER option to 0 allows to switch the filtering in XSUB socket off. Signed-off-by: Martin Sustrik <sustrik@250bpm.com>

2011-05-28Subscription matching moved from XSUB to SUB socketMartin Sustrik
This patch will prevent duplicate matching in devices in the future. Instead of matching in both XPUB and XSUB, it'll happen only in XPUB. Receiver endpoint will still filter messages via SUB socket. 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.
