core, jp: component handling + client handling refactoring: - SàT can now handle components - plugin have now a "modes" key in PLUGIN_INFO where they declare if they can be used with clients and or components. They default to be client only. - components are really similar to clients, but with some changes in behaviour: * component has "entry point", which is a special plugin with a componentStart method, which is called just after component is connected * trigger end with a different suffixes (e.g. profileConnected vs profileConnectedComponent), so a plugin which manage both clients and components can have different workflow * for clients, only triggers of plugins handling client mode are launched * for components, only triggers of plugins needed in dependencies are launched. They all must handle component mode. * component have a sendHistory attribute (False by default) which can be set to True to allow saving sent messages into history * for convenience, "client" is still used in method even if it can now be a component * a new "component" boolean attribute tells if we have a component or a client * components have to add themselve Message protocol * roster and presence protocols are not added for components * component default port is 5347 (which is Prosody's default port) - asyncCreateProfile has been renamed for profileCreate, both to follow new naming convention and to prepare the transition to fully asynchronous bridge - createProfile has a new "component" attribute. When used to create a component, it must be set to a component entry point - jp: added --component argument to profile/create - disconnect bridge method is now asynchronous, this way frontends can know when disconnection is finished - new PI_* constants for PLUGIN_INFO values (not used everywhere yet) - client/component connection workflow has been moved to their classes instead of being a host methods - host.messageSend is now client.sendMessage, and former client.sendMessage is now client.sendMessageData. - identities are now handled in client.identities list, so it can be updated dynamically by plugins (in the future, frontends should be able to update them too through bridge) - profileConnecting* profileConnected* profileDisconnected* and getHandler now all use client instead of profile
