Tyler Goodlet 8522f90000 Add type annots to exceptions mod 
Also add a `is_multi_cancelled()` predicate to test for
`trio.MultiError`s that contain entirely cancel signals.

Resolves #125

Tyler Goodlet 9fd3c42eb1 Port inter-process method calls to `Portal.run_from_ns()` 2020-12-22 10:39:47 -05:00
Tyler Goodlet 7134f35d6e Add `Portal.run_from_ns()` 
It turns out in order to maintain our sneaky little "call an `Actor`
method in this remote process" we still need the ability to invoke
functions from a namespace. We're currently using a "self" namespace as
a way to do this for internal inter-process method calling.  Either way,
I see no reason not to keep a public method for this invoke style (we
just won't market it) since it is still how the machinery works
underneath.

Tyler Goodlet a668f714d5 Allow passing function refs to `Portal.run()` 
This resolves and completes #69 allowing all RPC invocation APIs to pass
function references directly instead of explicit `str` names for the
target namespace and function (this is still done implicitly
underneath).  This brings us closer to `trio`'s task running API as well
as acknowledges that any inter-host RPC system (and API) will likely
need to be implemented on top of local RPC primitives anyway. Even if
this ends up **not** being true we can always go to "function stubs" as
part of our IAC protocol or, add a new method to do explicit namespace
calls: `.run_from_module()` or whatever everyone votes on.

Resolves #69

Further, this commit drops `Actor.statespace` from the entire system
since a user can easily get this same functionality using module
level variables. Fix docs to match all these changes (luckily mostly
already done due to example scripts referencing).

Tyler Goodlet 201771a521 'Fix mypy, change interal type name to `ReceiveStream`, settle on `.shield()`' 2020-12-17 12:01:49 -05:00
Tyler Goodlet 15ead6b561 Add a way to shield a stream's underlying channel 
Add a ``tractor._portal.StreamReceiveChannel.shield_channel()`` context
manager which allows for avoiding the closing of an IPC stream's
underlying channel for the purposes of task re-spawning. Sometimes you
might want to cancel a task consuming a stream but not tear down the IPC
between actors (the default). A common use can might be where the task's
"setup" work might need to be redone but you want to keep the
established portal / channel in tact despite the task restart.

Includes a test.

Tyler Goodlet e51c2620e5 End the `pdb` SIGINT handling madness 
Turns out this is a lower level issue in terms of the stdlib's default
`pdb.Pdb` settings and how they conflict with `trio`s cancellation and
KBI handling. The details are hashed out more thoroughly in
python-trio/trio#1155. Maybe we can get a fix in trio so things are
solved under our feet :)

Tyler Goodlet 3b8684f655 Always call `Actor.cancel()` at end of root's main task 
It's simpler and the only real logical difference is logging messages.
This should also give us an overall consistent tear down sequence.

Tyler Goodlet f60321a35a Always cancel service nursery last 
The channel server should be torn down *before* the rpc
task/service nursery. Do this explicitly even in the root's main task
to avoid a strange hang I found in the pubsub tests. Start dropping
the `warnings.warn()` usage.

Tyler Goodlet 573b8fef73 Add better actor cancellation tracking 
Add `Actor._cancel_called` and `._cancel_complete` making it possible to
determine whether the actor has started the cancellation sequence and
whether that sequence has fully completed. This allows for blocking in
internal machinery tasks as necessary. Also, always trigger the end of
ongoing rpc tasks even if the last task errors; there's no guarantee the
trio cancellation semantics will guarantee us a nice internal "state"
without this.
