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>

2011-06-20Optimise block/non-block switching in mailbox_tFabien Ninoles
For the platforms that don't support MSG_DONTWAIT the reader socket in mailbox_t was kept in non-blocking state and flipped to blocking state and back when blocking read was requested. Now, the state is preserved between calls and flipped only if different type of operation (block vs. non-block) is requested.

2011-06-19Session termination error fixedMartin Sustrik
When session is already terminating and reconnection happens at that point, the session should not create new pipe to its socket. 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>

2011-05-03Minor patch to keep ICC compiler happyMartin Sustrik
ICC doesn't recognise that assert(false) terminates the program and thus complains that certain functions have no return values. This patch supplies dummy return values to keep the compiler happy. Signed-off-by: Martin Sustrik <sustrik@250bpm.com>
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>
2011-05-02Yet one more fix related to PUB socket and multipart messagesMartin Sustrik
