Why This Fix Works in Production

  • Trigger: Retire wrap_socket from ssl and tests
  • Mechanism: Updates the trove and CI to support the Python 3.12 release announcement, addressing the deprecation of wrap_socket in Python 3.12.
  • Why the fix works: Updates the trove and CI to support the Python 3.12 release announcement, addressing the deprecation of wrap_socket in Python 3.12. (first fixed release: 7.1.0).
Production impact:
  • If left unfixed, the same config can fail only in production (env differences), causing startup failures or partial feature outages.

Why This Breaks in Prod

  • Shows up under Python 3.12 in real deployments (not just unit tests).
  • Production symptom (often without a traceback): Retire wrap_socket from ssl and tests
