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).

2012-04-18Discard pending surveys when (X)SURVEYOR socket disappearsMartin Sustrik
This is an optimisation. The idea is that when surveyor disappears it makes no sense to process any surveys it have sent. There are two cases handled: - when (X)SURVEYOR socket is closed any unsent outbound messages are discarded - when (X)RESPONDENT detects that its peer have disconnected it drops any unprocessed messages that have been received from it Signed-off-by: Martin Sustrik <sustrik@250bpm.com>
2012-04-17"Survey" pattern implementedMartin Sustrik
Survey pattern is "multicast with reply". There are two roles: surveyor and respondent. Surveyor publishes a survey which gets delivered to all connected respondents. Each repondent can send a response to the survey. All the responses are delivered to the original surveyor. Once the surveyor decides that the survey is over (e.g. deadline was reached) it can send initiate survey. Late responses from old surveys are automatically discarded by the surveyor socket. Socket types: SURVEYOR, XSURVEYOR, RESPONDENT, XRESPONDENT Patch also includes a test program with surveoyr, two respondents and an intermediary device.
