- Implements RC's underlying ConfigDBManager in Swift
- Migrates database queue to an actor
- Refactors some of the mocks out of the the unit tests
- Pod testing works on Xcode 16. Other CI failures look to be transition-related

Fixes synchronous db reads from ObjC

Do clients of this API need to change now that it's async?

Yes. That should be done in this PR

This file is the internal API for the DB. The guts of the implementation is in DatabaseActor which is the code that was previously in a dedicated queue.

This looks reasonable to me. There are potentially some DB optimizations we could do (e.g., creating the prepared statements once and resetting them to bind new values and then finalizing them on deinit) but I think that's beyond the scope of this Swift re-write and would be better to leave it closer to the original implementation (especially since you weren't sure if we wanted to keep the sqlite implementation).

I think the toV2Namespace is useless.

I think this is inserting into the wrong table. It should be fetch_metadata_v2.
The objc impl:
#define RCNTableNameMetadata "fetch_metadata_v2"
/* snip */
static const char *SQL =
"INSERT INTO " RCNTableNameMetadata

Yes - good catch - It's sometimes surprising what the AI misses.

I commented or resolved all comments except for most of the ones in DatabaseActor which I'll look at in a few hours |
|
Going to merge it here. Thanks for the reviews @ncooke3 and @andrewheard. One note is that callbacks from the Database APIs are not wrapped in main thread because they're already in a Task, can cause deadlocks and should be replaced by async APIs when the callers are in Swift. |
