// IndexedDBBucketContext manages the per-bucket IndexedDB state, and other
// important context like the backing store and lock manager.
//
// IndexedDBBucketContext will keep its backing store around while any of these
// is true:
// * There are handles referencing the bucket context,
// * There are outstanding blob references to this database's blob files, or
// * The bucket context is in-memory (i.e. an incognito profile).
//
// When these qualities are no longer true, `RunTasks()` will invoke
// `ResetBackingStore()`, which returns `this` to an uninitialized state.
//
// TODO(crbug.com/40279485): it's intended that each bucket gets its own
// IndexedDB task runner. To facilitate IndexedDB code running on multiple task
// runners, `IndexedDBBucketContext` is in the process of becoming the single
// point of communication between classes running on the main task runner, such
// as `IndexedDBContextImpl`, and those that pertain to a specific bucket and
// therefore run on a bucket's IDB task runner, such as `IndexedDBDatabase` or
// `IndexedDBCursor`.
