.. towncrier release notes start
tractor 0.1.0a3 (2021-11-01)
============================
Features
--------
- Switch to using the ``trio`` process spawner by default on windows. (#166)
This gets windows users debugger support (manually tested) and in
general a more resilient (nested) actor tree implementation.
- Add optional `msgspec <https://jcristharif.com/msgspec/>`_ support
as an alernative, faster MessagePack codec. (#214)
Provides us with a path toward supporting typed IPC message contracts. Further,
``msgspec`` structs may be a valid tool to start for formalizing our
"SC dialog un-protocol" messages as described in `#36
<https://github.com/goodboy/tractor/issues/36>`_`.
- Introduce a new ``tractor.trionics`` `sub-package`_ that exposes
a selection of our relevant high(er) level trio primitives and
goodies. (#241)
At outset we offer a ``gather_contexts()`` context manager for
concurrently entering a sequence of async context managers (much like
a version of ``asyncio.gather()`` but for context managers) and use it
in a new ``tractor.open_actor_cluster()`` manager-helper that can be
entered to concurrently spawn a flat actor pool. We also now publicly
expose our "broadcast channel" APIs (``open_broadcast_receiver()``)
from here.
.. _sub-package: ../tractor/trionics
- Change the core message loop to handle task and actor-runtime cancel
requests immediately instead of scheduling them as is done for rpc-task
requests. (#245)
In order to obtain more reliable teardown mechanics for (complex) actor
trees it's important that we specially treat cancel requests as having
higher priority. Previously, it was possible that task cancel requests
could actually also themselves be cancelled if a "actor-runtime" cancel
request was received (can happen during messy multi actor crashes that
propagate). Instead cancels now block the msg loop until serviced and
a response is relayed back to the requester. This also allows for
improved debugger support since we have determinism guarantees about
which processes must wait before hard killing their children.
- Drop Python 3.8 support in favor of rolling with two latest releases
for the time being. (#248)

Introduce a new `sub-package`_ that exposes all our high(er) level trio primitives and goodies, most importantly:
- A new ``open_actor_cluster`` procedure is available for concurrently spawning a number of actors.
- A new ``gather_contexts`` procedure is available for concurrently entering a sequence of async context managers.
