Make a ContentProvider for reading list items.

so far only supports querying and responds with fake data. we haven't finalized the schema and SQL implementation yet. just wanted to get some feedback if any.

Maybe now would be the time to actually factor out this pattern into a place that can be shared between all the content providers.

Margaret, did you have a change to work on that > 'PerProfileProvider' parent class idea? The result of that was PerProfileDatabases, which moved the copy/pasted profile-related code into a common class. The current PerProfileContentProvider is confusingly named, and should be renamed to SQLiteBridgeContentProvider. See bug 947506 for that (a volunteer is working on that, but I might just wrap that up and land it so I can use it for the home panel data stuff). But yes, I've thought about creating a common parent class that implements the basic ContentProvider methods, with abstract *InTransaction methods for the individual content provider to implement. However, I never had time to do this. Maybe that could be a good bug for sola to file and fix :)

Implemented requested changes. To continue with the implementation, I need rough estimate of the reading_list table schema so I can start writing some queries. Bug #889351 (the UI) depends on this because there no real data for excerpt and readTime UI. Bug #959297 is blocked on this because there's no where to store the excerpt and readTime data from the article. @margaret: i'll file a bug the make an abstract ContentProvider class and start working on it. Should this depend on that?

Can I start with this schema? https://etherpad.mozilla.org/MSS4ZtisSj

(In reply to Sola Ogunsakin [:sola] from comment #8) > Can I start with this schema? https://etherpad.mozilla.org/MSS4ZtisSj Drive-by: looks fine to me. Keep in mind that you'll probably have to update the IndexedDB schema accordingly. See: http://mxr.mozilla.org/mozilla-central/source/mobile/android/chrome/content/browser.js#7965

(In reply to Sola Ogunsakin [:sola] from comment #8) > Can I start with this schema? https://etherpad.mozilla.org/MSS4ZtisSj Looks reasonable to me!

Step taken to test migration: -added reading list items and bookmarks w/ DB version 17. -bumped DB version to 18 -after migration, saw the same reading list items in UI with same title and urls. No non-reading list bookmarks where moved over. -tested adding/removing of bookmark items -tested adding/removing of reading list items -tested re-adding reading list item marked as 'deleted' -will run tests on try to see if anything is broken

As Lucas mentioned in bug 971413, the patch there will bitrot this one slightly. You'll want to remove the Reader:ListCountUpdated and toast bits from RemoveReadingListItemTask -- Reader:Remove will take care of that on its own. Just a heads up to be on the lookout!

Alright, thanks for the heads up

Implemented requested changes Aside: added SCROLL_POSITION column to the reading list table (it defaults to 0). So we don't need a migration for bug 857990.

N.B.: any changes you make to BrowserContract need to be reflected in the copy of it in android-sync, and the /sync/ classes that touch it -- both as pull requests to <https://github.com/mozilla-services/android-sync>.

Hmm.. alright seems like moving FIXED_READING_LIST_ID and READING_LIST_FOLDER_GUID will require touching a lot of stuff and is beyond the scope of this bug. I'll file another bug to make these changes and update the sync code.

(In reply to Sola Ogunsakin [:sola] from comment #35) > I believe all the tests/db updates are synchronous, Concurrency was just an example. Other things can go wrong too (e.g. buggy disk driver, damaged disk), and concurrency may be added in the future! All in all, there's little reason to get a value from a data structure and later assert that it's the same value when you try to get it again when you're not testing the data structure - it just introduces the potential for additional errors.
