Braindump

• Tp:Approver which is a process that runs in the workspace and handles all channel notifications.
  • Perhaps a kded module?

• Needs to have some registry of all installed handlers for each channel type. (will .client files and looking at the bus do for this?)
  • Client files need to be extended so that they contain a translatable string for the name of the handler.

• It can probably register itself as an approver for everything. The CD will never activate an approver if there is no handler.
  • It is not clear how to handle the various types of tubes channels. Perhaps the .client files should contain extra information for the approver in this case.
    • Another choice is to specify that every tubes handler will have its own approver.
    • Experiment with krfb/krdc.

• Should respect user preferences for preferred handlers for a given channel type.
  • This should somehow intersect with Tp::ChannelDispatchOperation::possibleHandlers()

• Companion kcm module to allow the user to select default text channel handler, default voice channel handler etc...
  • Processes that only exist on the bus cannot be considered for the kcm, as we don't know whether they are available when the actual channel is dispatched.

• Talk to sjoerd in #telepathy to make sure we implement this in a way that is as compatible as possible with how Gnome are doing it.

Steps

• As a first step, implement an approver that approves text/call/file transfer channels and use only Tp::ChannelDispatchOperation::possibleHandlers() to select the handler.

• Extend the spec to support the new features.

• Implement the kcm that reads the client files and saves order preferences with kconfig.

• Extend the approver to intersect the kcm's saved order of handlers with Tp::ChannelDispatchOperation::possibleHandlers().

• Find out what to do with tube channels.
