Revert "Implement SP wire protocol"

2012-06-13T08:25:18+00:00

This reverts commit a34ea4d80609395150742259fd8c9caa4409e961.

Topic filter implemented

2012-05-26T07:17:47+00:00

The filter is build into libxs rather than being a plug-in.
It's ID is XS_FILTER_TOPIC.

The filter assumed that the messages are text-based and consider
binary 0 to be a delimiter separating message topic from the message
body. Use of the delimiter is not mandatory though. If binary zero
is not present, whole message is used for matching.

The topic is separated into elements using dots, e.g.
"animals.dogs.fluffy".

Subscriptions match individual elements. Each element can be matched
by either literal string or a wildcard (*), for example:
"animals.*.fluffy" matches all animals called Fluffy irrsepctive
of whether they are dogs, cats or whatever.

Implement SP wire protocol

2012-05-25T12:02:16+00:00

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).

"Survey" pattern implemented

2012-04-17T05:30:52+00:00

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.
