Previously whenever an `ActorNursery.start_actor()` call did not receive
a `bind_addrs` arg we would allocate the default `(localhost, 0)` pairs
in the parent, for UDS this obviously won't work nor is it ideal bc it's
nicer to have the actor to be a socket server (who calls
`Address.open_listener()`) define the socket-file-name containing their
unique ID info such as pid, actor-uuid etc.
As such this moves "random" generation of server addresses to the
child-side of a subactor's spawn-sequence when it's sin-`bind_addrs`;
i.e. we do the allocation of the `Address.get_random()` addrs inside
`._runtime.async_main()` instead of `Portal.start_actor()` and **only
when** `accept_addrs`/`bind_addrs` was **not provided by the spawning
parent**.
Further this patch get's way more rigorous about the `SpawnSpec`
processing in the child inside `Actor._from_parent()` such that we
handle any invalid msgs **very loudly and pedantically!**
Impl deats,
- do the "random addr generation" in an explicit `for` loop (instead of
prior comprehension) to allow for more detailed typing of the layered
calls to the new `._addr` mod.
- use a `match:/case:` for process any invalid `SpawnSpec` payload case
where we can instead receive a `MsgTypeError` from the `chan.recv()`
call in `Actor._from_parent()` to raise it immediately instead of
triggering downstream type-errors XD
|_ as per the big `#TODO` we prolly want to take from other callers
of `Channel.recv()` (like in the `._rpc.process_messages()` loop).
|_ always raise `InternalError` on non-match/fall-through case!
|_ add a note about not being able to use `breakpoint()` in this
section due to causality of `SpawnSpec._runtime_vars` not having
been processed yet..
|_ always return a third element from `._from_rent()` eventually to be
the `preferred_transports: list[str]` from the spawning rent.
- use new `._addr.mk_uuid()` and pass to new `Actor.__init__(uuid: str)`
for all actor creation (including in all the mods tweaked here).
- Move to new type-alias-name `UnwrappedAddress` throughout.
