Add support for ``trio >= 0.22`` and support for the new Python 3.11
|
||
|
|
``[Base]ExceptionGroup`` from `pep 654`_ via the backported
|
||
|
|
`exceptiongroup`_ package and some final fixes to the debug mode
|
||
|
|
subsystem.
|
||
|
|
|
||
|
|
This port ended up driving some (hopefully) final fixes to our debugger
|
||
|
|
subsystem including the solution to all lingering stdstreams locking
|
||
|
|
race-conditions and deadlock scenarios. This includes extending the
|
||
|
|
debugger tests suite as well as cancellation and ``asyncio`` mode cases.
|
||
|
|
Some of the notable details:
|
||
|
|
|
||
|
|
- always reverting to the ``trio`` SIGINT handler when leaving debug
|
||
|
|
mode.
|
||
|
|
- bypassing child attempts to acquire the debug lock when detected
|
||
|
|
to be amdist actor-runtime-cancellation.
|
||
|
|
- allowing the root actor to cancel local but IPC-stale subactor
|
||
|
|
requests-tasks for the debug lock when in a "no IPC peers" state.
|
||
|
|
|
||
|
|
Further we refined our ``ActorNursery`` semantics to be more similar to
|
||
|
|
``trio`` in the sense that parent task errors are always packed into the
|
||
|
|
actor-nursery emitted exception group and adjusted all tests and
|
||
|
|
examples accordingly.
