Matthew Hodgson 8e1c26067b ⏺ Summary of remaining Twisted defer usage: ...

- 0 @defer.inlineCallbacks — all converted to async def
  - 12 defer.ensureDeferred — reactor entry points (startup, shutdown, render)
  - 22 defer.Deferred() — in Linearizer, ReadWriteLock, AwakenableSleeper, DeferredEvent (old implementations)
  - 21 defer.gatherResults — in fallback paths and old implementations
  - 11 defer.succeed/fail — immediate value wrapping in old implementations
  - 3 defer.FirstError — in fallback paths
  - 13 defer.TimeoutError — in timeout_deferred and its callers

  The majority (22 + 21 + 11 + 13 = 67) are in the old Deferred-based utility implementations (Linearizer, ReadWriteLock, ObservableDeferred, timeout_deferred, etc.) that already have native replacements (NativeLinearizer,
  NativeReadWriteLock, ObservableFuture, native_timeout, etc.). These will be removed when callers switch to the native versions.

  The 12 defer.ensureDeferred are in reactor entry points that will be removed when reactor.run() → asyncio.run().

  The codebase is now in a clean transitional state where:
  1. All Twisted imports are conditional (try/except ImportError)
  2. ContextVar is the primary logcontext storage
  3. Test base class is stdlib (unittest.TestCase)
  4. CancelledError is asyncio.CancelledError in production code
  5. @defer.inlineCallbacks is eliminated (0 remaining)
  6. yieldable_gather_results uses asyncio.gather (with Twisted fallback)
  7. Module API is fully async (no more Deferred return types)
  8. Twisted is optional in pyproject.toml
