2012-05-26Topic filter implementedMartin Sustrik
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.

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).
