As much as is possible given we currently do some graceful cancellation join-waiting on any connected sub-actors whenever an active `local_nursery: AcrtorNursery` in the post-rpc teardown sequence of `handle_stream_from_peer()` is detected. In such cases we try to allow the higher level inter-actor (task) context(s) to fully cancelled-ack before conducting IPC machinery shutdown. The main immediate motivation for all this is to support unit testing the `.ipc._server` APIs but in the future may be useful for anyone wanting to use our modular IPC transport layer sin-"actors". Impl deats, - drop passing an `actor: Actor` ref from as many routines in `.ipc._server` as possible instead opting to use `._state.current_actor()` where abs needed; thus the fns dropping an `actor` input param are: - `open_ipc_server()` - `IPCServer.listen_on()` - `._serve_ipc_eps()` - `.handle_stream_from_peer()` - factor the above mentioned graceful remote-cancel-ack waiting into a new `maybe_wait_on_canced_subs()` which is called from `handle_stream_from_peer()` and delivers a maybe-`local_nursery: ActorNursery` for downstream logic; it's this new fn which primarily still needs to call `current_actor()`. - in `handle_stream_from_peer()` also use `current_actor()` to check if a handshake is needed (or if it was called as part of some actor-runtime-less operation like our unit test suite!). - also don't pass an `actor` to `._rpc.process_messages()` see how-n-why below.. Surrounding ipc-server client/caller adjustments, - `._rpc.process_messages()` no longer takes an `actor` input and now calls `current_actor()` instead. - `._portal.open_portal()` is adjusted to ^. - `._runtime.async_main()` is adjusted to the `.ipc._server`'s removal of `actor` ref passing. Also, - drop some server `log.info()`s to `.runtime()` |
