[Sugar-devel] [PATCH] Simple NetworkManager-0.9 port

Daniel Drake dsd at laptop.org
Thu Sep 15 15:36:58 EDT 2011


Adapt sugar to NetworkManager-0.9 API changes.

The major change here is the removal of the user-level connections
mechanism; instead of storing connection information in Sugar,
NetworkManager now Manages our Networks for us.

However, some level of interfacing/monitoring NM is now needed,
implemented with the Connections and Connection classes in
jarabe.model.network.

If found, connections in sugar's connections.cfg are automatically
migrated, and then connections.cfg is deleted. Similarly, if modem
connection details are found in gconf, they are migrated into NM
and then the gconf keys are unset.

The existing network code is far from perfect and actually quite messy.
In this port I've tried not to make fundamental changes to improve this,
in order to keep task complexity down and aid review.
In the medium term I do plan to improve this code, by moving it to
use gobject-introspection on libnm, and rewriting/restructuring at the
same time. By letting libnm do most of the work for us, this layer can
be greatly simplified. However, libnm and gobject-introspection
improvements are needed first, which I will continue to work on.
