PackageKit backend for Software Center: short week 5 report

This week I continued work on the install backend, especially connecting the PackageKit transaction signals to the software-center’s TransactionWatcher (also abstracted by me some time ago).

The challenge stands in differences from PackageKit and AptDaemon, such as in AD, after preparing a transaction and manually commiting it,  one has access to the transaction object, and can watch for progress changes; in PK, after a transaction is launched, there are two ways of getting access to it: first by listening to a TransactionListChanged signal in D-Bus and second by watching the objects returned by the progress_callback callback.

The current approach, helped closely by hue-see (hughsie) on #PackageKit is to get the transactions from the callback and listen to the gobject notify::<property> signals.

More to come next week, stay tuned!
