I have a task on my plate at OpenSky where it would be extremely helpful to have a way to listen on many events. Beyond the standard Symfony2 events (e.g. core.request, core.exception), we have plenty of custom events in place where this feature would really shine. Here's a snippet from our spec:
The AMQP routing wildcard format (used by ActiveMQ, HornetQ, RabbitMQ, et > al.) would work well: > > * > http://hornetq.sourceforge.net/docs/hornetq-2.0.0.GA/user-manual/en/html/wildcard-syntax.html > * http://www.rabbitmq.com/faq.html#wildcards-in-topic-exchanges > > The "#" and "*" symbols would be used as multi-word or single-word > wildcards, respectively, where words are separated by periods. This meshes > well with Symfony2's existing naming convention for events (dot-separated), > which we also use for our application's custom events. > Basically... a listening on core.* would catch core.request but not core.request.foo (if such a thing existed). Listening on core.# would catch both and really anything starting with "core.". I realize there's no requirement for events to be named in this dot-separated format, but our app happens to follow the same conventions as the core framework events. I can either implement this as a PR for Symfony2's EventDispatcher, or perhaps as a bundle that replaces the EventDispatcher service (or redefines "event_dispatcher.class"). The Form component appears to be the only hard reference to Symfony2's EventDispatcher class, but I think that's OK because it uses an internal dispatcher for its own events. Also, Johannes mentioned that this would add a non-trivial performance cost to event dispatching (since we'd have to match some patterns instead of only doing array index checks). Perhaps that's more reason for it to be a bundle. Thoughts? Would anyone else even benefit from this kind of feature? -- jeremy mikola -- If you want to report a vulnerability issue on symfony, please send it to security at symfony-project.com You received this message because you are subscribed to the Google Groups "symfony developers" group.
