Implement subscriber meta events in client #17

Closed ecorm closed 2 years ago

ecorm commented 9 years ago

Implement subscriber meta events, as per the advanced spec.

ecorm commented 9 years ago

Client requirements:

HELLO.Details.roles.subscriber.features.subscriber_metaevents|bool := true
SUBSCRIBE.Options.metatopics|list
SUBSCRIBE.Options.metaonly|bool
Receiving EVENT.Details.metatopic|URI
Receiving other metatopic information in EVENT.Details

When SUBSCRIBE.Details.metaonly|bool is true, "normal" events on the subscribed topic will not be dispatched to the meta-only subscriber.

The should be no special treatment required by the client.

This feature seems to overlap with the Meta API feature, so it might be an old, leftover idea that never got removed. I've raised an issue in https://github.com/tavendo/WAMP/issues/157, where I ask, among other things, if this feature is indeed redundant.

This spec proposal is now gone and has been replaced with the Subscription Meta API.
