`Sendable` support #1795

NachoSoto · 2022-08-05T20:02:04Z

Main changes:

Sendable conformances to all types that are thread-safe
@unchecked Sendable for types that the compiler can't enforce, but with documentation as to why
Made classes that aren't mocked final (note that this doesn't change the API, because none of these were open to begin with)
Made some classes thread-safe that weren't (like DeviceCache)

For the non-final classes, I've actually managed to compile the SDK with all of them as final and Sendable, to make sure that making them @unchecked Sendable didn't hide any other issues.

Future improvements:

We'll see if we keep this or not.

I think it's not a bad idea to keep this so we ensure we maintain this level of correctness prior to Swift 6.0

The type is now immutable, so the compiler ensures it's thread-safe. For CSDK-379. Extracted #1795 to make it easier to review this fix in isolation.

This is almost ready, but it will be a lot easier to review once all those dependent PRs are merged.

        } else {
-            workerQueue.async(execute: block)
+            DispatchQueue.main.async(execute: block)


should this be self.mainQueue?

Oh yeah good call.

Oh I know why I did this: there is some magic that allows passing a @MainActor block to only DispatchQueue.main, but not if we inject any random queue:

ohhh right, that makes sense. Could you add a comment for the future?

    private let maxJitterInSeconds: Double = 5

    static let `default`: OperationDispatcher = .init()

-    func dispatchOnMainThread(_ block: @escaping () -> Void) {
+    func dispatchOnMainThread(_ block: @escaping @Sendable () -> Void) {


Should this be made private now? Is there any scenario where we should choose to go with main thread and not main actor even when Swift Concurrency is available?

Eventually we can get rid of this, but that seems like a bigger change. For existing code that does not use the new Swift "structured" concurrency, we might not want to change the semantics if we don't need to.

There's still a few places using dispatchOnMainThread that we might not want to change until we use @MainActor (or other custom actors) in more places.

Let me know what you think, we can migrate more of these to dispatchOnMainActor in a following PR.
