backend, frontends: message refactoring (huge commit): /!\ several features are temporarily disabled, like notifications in frontends next step in refactoring, with the following changes: - jp: updated jp message to follow changes in backend/bridge - jp: added --lang, --subject, --subject_lang, and --type options to jp message + fixed unicode handling for jid - quick_frontend (QuickApp, QuickChat): - follow backend changes - refactored chat, message are now handled in OrderedDict and uid are kept so they can be updated - Message and Occupant classes handle metadata, so frontend just have to display them - Primitivus (Chat): - follow backend/QuickFrontend changes - info & standard messages are handled in the same MessageWidget class - improved/simplified handling of messages, removed update() method - user joined/left messages are merged when next to each other - a separator is shown when message is received while widget is out of focus, so user can quickly see the new messages - affiliation/role are shown (in a basic way for now) in occupants panel - removed "/me" messages handling, as it will be done by a backend plugin - message language is displayed when available (only one language per message for now) - fixed :history and :search commands - core (constants): new constants for messages type, XML namespace, entity type - core: *Message methods renamed to follow new code sytle (e.g. sendMessageToBridge => messageSendToBridge) - core (messages handling): fixed handling of language - core (messages handling): mes_data['from'] and ['to'] are now jid.JID - core (core.xmpp): reorganised message methods, added getNick() method to client.roster - plugin text commands: fixed plugin and adapted to new messages behaviour. client is now used in arguments instead of profile - plugins: added information for cancellation reason in CancelError calls - plugin XEP-0045: various improvments, but this plugin still need work: - trigger is used to avoid message already handled by the plugin to be handled a second time - changed the way to handle history, the last message from DB is checked and we request only messages since this one, in seconds (thanks Poezio folks :)) - subject reception is waited before sending the roomJoined signal, this way we are sure that everything including history is ready - cmd_* method now follow the new convention with client instead of profile - roomUserJoined and roomUserLeft messages are removed, the events are now handled with info message with a "ROOM_USER_JOINED" info subtype - probably other forgotten stuffs :p
