1176187 - Lazy HomeProvider SQLite migration is only triggered from JavaScript

Status: RESOLVED INCOMPLETE

(Firefox for Android Graveyard :: Awesomescreen, defect)

Description

[Sebastian Kaspari (:sebastian; :pocmo)]

While developing a new home panel layout that required a database migration, I noticed that the migration code inside HomeProvider.jsm is only lazily triggered when an addon is actively using a database connecting (getDatabaseConnection()).

The Java code that is building the panel UI does not trigger the migration and therefore has to be backwards compatible across all schema versions (theoretically). This adds some complexity.

We could:
* Trigger the migration from the Java side too. That's probably rather complex.
* Perform the migration not lazily but as soon as HomeProvider.jsm is loaded (potential race condition?).
