Change Details

**GCompris Architecture Reconfig Discussion** **Purpose: Provide an alternative binary version with a small footprint in which activities are downloaded on demand.** Phases of development: P-1 -> Separate ActivityInfo.qml and icons from some activities and make new ActivityInfo.rcc. See whether we are successfully able to load them. The activities selected here will not have have any inter-dependencies on some other activity. P-2 -> Now for the activities that are inter-dependent, I think we'll have to code a new download manger in a way that it downloads all dependencies required for running that activity and nothing extra. As mentioned earlier by Johnny, erase_2clic needs erase. So download manager's code will manage accordingly. P-3 -> Now providing option of selective activity download to end-user in a way that it is easy to understand. I suggest that we have two buttons at the very beginning of the app, that prompts user with two options/buttons: a) Full Download b) Selective download P-4 -> Versioning of APIs. I'm a little unsure here. We have two issues to handle here: a) Avoid download of duplicate activity on the user end b) check and update correct version of activity to core. I think one of the ways could be, while we are creating a separate activityInfo.rcc for every activity, the download manger could check the corresponding ActivityInfo.qml file in activityInfo.rcc for version and then perform the necessary action. P-5 -> If all of the above is done, I think we could also think of implementing an option that allows user to delete a particular activity. Suppose someone has completed all the levels of the activity and doesn't use the activity anymore then this option would help there. Implementation of P-5 -> We can add a ActivityHandler.cpp in the core that will keep track of this. In my humble opinion, this would take around 12 weeks including the testing.

See whether we are successfully able to load them. The activities selected here will not have have any inter-dependencies on some other activity. P-2 -> Now for the activities that are inter-dependent, we'll have a new 'activitiy downloader' that drives the download manager in a way that it downloads all dependencies required for running that activity and nothing extra. For example erase_2clic needs erase. So activity dowloader's code will manage accordingly. P-3 -> Each Activity icon in the main menu shows if it is locally present or not. If the children enters a non local activity it is downloaded. There is no way for the children to erase a specific downloaded activity. P-4 -> Versioning of APIs. We have two issues to handle here: a) make sure inter dependant activities are kept in sync b) check and update correct version of activity to core. To do this, each ActivityInfo.qml contains the activities it depends on and the version of the core it expects. The activity downloaded checks that and perform the necessary downloads. P-5 -> We can implement a cleanup of least used activities like a browser manages a cache. We provide in the configuration a cache option with 2 values: "keep all activities", "remove unused activities". When GCompris starts (or quits), we trigger a cleanup of least used activities.
