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>

2012-02-16io_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>

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>

Signed-off-by: Martin Sustrik <sustrik@250bpm.com>
2011-07-11ZMQ_FILTER option removedMartin Sustrik
The filtering is now done depending on the socket type. SUB socket filters the messages (end-to-end filtering) while XSUB relies on upstream nodes to do (imprefect) filtering. 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>
2011-04-21Message-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.

These are just placeholders. At the moment XPUB behaves th same as PUB and XSUB as SUB. Signed-off-by: Martin Sustrik <sustrik@250bpm.com>
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>

2010-08-25WIP: 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.
