Thread Safety of Built-in Types

• Terminology

aync-kernel utilises aiologic for its thread-safe primitives.

async_kernel.pending.Pending

Guarantees

• Internally synchronised

  • All Public methods can be safely called from any thread.
  • Instance are sync/async awaitable from any thread with any backend.

• Limitations

  add_done_callback: The callback is called from the thread in which it is set so should provide it's own synchronisation as needed.

async_kernel.caller.Caller

Caller is thread-local in CPython and context-local in Pyodide.

Guarantees

• Internally synchronised

• Limitations

  • queue_call is internally synchronised per-function after the first call (per-function) has returned.

async_kernel.common.Fixed

Guarantees

• Internally synchronised
