Tyler Goodlet 5f55c7ca00 Add `Actor.cancel_soon()` for sync self destruct 
Add a sync method that can be used to cancel the current actor from
a synchronous context. This is useful in debugging situations where
sync debugger code may need to kill the process tree.

Also, make the internal "lifetime stack" a global var; easier to manage
from client code that may was to add callbacks prior to the actor
runtime being fully setup.

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 08ff989631 Add some comments 2020-10-13 11:59:18 -04:00
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.

Tyler Goodlet 79c38b04e7 Report `trio.Cancelled` when exhausting portals.. 
For reliable remote cancellation we need to "report" `trio.Cancelled`s
(just like any other error) when exhausting a portal such that the
caller can make decisions about cancelling the respective actor if need
be.

Resolves #156
 2020-10-12 23:28:36 -04:00
Tyler Goodlet 0e344eead8 Add a "cancel arrives during a sync sleep in child" test 
This appears to demonstrate the same bug found in #156. It looks like
cancelling a subactor with a child, while that child is running sync code,
can result in the child never getting cancelled due to some strange
condition where the internal nurseries aren't being torn down as
expected when a `trio.Cancelled` is raised.

Tyler Goodlet 83a45119e9 Add "root mailbox" contact info passing 
Every subactor in the tree now receives the socket (or whatever the
mailbox type ends up being) during startup and can call the new
`tractor._discovery.get_root()` function to get a portal to the current
root actor in their tree. The main reason for adding this atm is to
support nested child actors gaining access to the root's tty lock for
debugging.

Also, when a channel disconnects from a message loop, might as well kill
all its rpc tasks.

Tyler Goodlet fc2cb610b9 Make "hard kill" just a `Process.terminate()` 
It's not like any of this code is really being used anyway since we
aren't indefinitely blocking for cancelled subactors to terminate (yet).
Drop the `do_hard_kill()` bit for now and just rely on the underlying
process api. Oh, and mark the nursery as cancelled asap.
