A basic d-bus interface enabling the use by a new Gnome-Do plugin for Gpodder.
The attached patches implement a basic d-bus interface enabling the use by a
new Gnome-Do plugin for Gpodder. The changes are implemented on the trunk of
the Git repository. Preliminary source for the plugin can be retrieved from
https://code.launchpad.net/~iwanvanderkleijn/do-plugins/gpodder. Code retrieved
from this repository needs to be compiled. I will activate an PPA on Launchpad
in order to offer a preliminary binary. The plugin will be proposed for merging
with the main trunk of Gnome-Do in the following days.
The interface is implemented separated from the current "org.gpodder.interface"
aka "/gui" d-bus interface / object_path. The new interface / object_path can
be referred to as "org.gpodder.podcasts" & "/podcasts. For interface details
see down. In this way the methods interacting directly with the GUI and methods
manipulating podcasts/episodes can be logically separated (while maintaining
compatibility with any eventual application using the current d-bus interface).
DBusPodcastsProxy deliberately does not use the api module as interaction with
gpodder through Gnome-Do invariably will involve a certain degree of
interaction with the GUI. Further more, there are issues with either the python
dbus implementation and the NBus Mono implementation which leads to issues with
None types in strings etc. The DBusPodcastsProxy is "safe" to work with NBus.
ISSUE: the current plugin is usable and supports retrieval of podcasts &
episodes with display of podcast-cover and episode state (new, downloaded,
deleted etc) through the Gnome-Do interface. The podcasts can be updated,
downloaded, played and deleted. However, changes in the episode state are not
immediately reflected. For this an event/notification mechanism needs to be
incorporated.
