Tyler Goodlet 63d067792c Rename `StreamQueue` to `MsgpackStream` 
Prepares for other possible interchange formats plus it wasn't really
a queue, just a TCP stream wrapper + `msgpack` interchange.

Tyler Goodlet dc5cc040e6 Try to support waiting on Windows processes 
This pokes around a little in `trio` hazmat but it *should

Tyler Goodlet 7014a07986 Add "spawn" start method support 
Add full support for using the "spawn" process starting method as per:
https://docs.python.org/3/library/multiprocessing.html#contexts-and-start-methods

Add a  `spawn_method` argument to `tractor.run()` for specifying the
desired method explicitly. By default use the "fastest" method available.
On *nix systems this is the original "forkserver" method.

This should be the solution to getting windows support!

Tyler Goodlet d75739e9c7 Factor process creation into a separate factory

"spawn method" stuff and factor current forkserver steps into it.

Tyler Goodlet 616192d853 Don't use async gen functions for the stream API 
As mentioned in prior commits there's currently a bug in Python that
make async gens **not** task safe. Since this is the core cause of almost
all recent problems, instead implement our own async iterator derivative of
`trio.abc.ReceiveChannel` by wrapping a `trio._channel.MemoryReceiveChannel`.
This fits more natively with the memory channel API in ``trio`` and adds
potentially more flexibility for possible bidirectional inter-actor streaming
in the future.

Huge thanks to @oremanj and of course @njsmith for guidance on this one!

Tyler Goodlet 41c202db68 Add a multi-task subscriber test 
In combination with `.aclose()`-ing the async gen instance returned from
`Portal.run()` this demonstrates the python bug:
https://bugs.python.org/issue32526

I've commented out the line that triggers the bug for now since this
case provides motivation for adding our own `trio.abc.ReceiveMemoryChannel`
implementation to be used instead of async gens directly (returned from
`Portal.run()`) since the latter is **not** task safe.
 2019-02-15 17:04:41 -05:00
Tyler Goodlet 61680b3729 Use a receive mem channel inside portals 
For now stop `.aclose()`-ing all async gens on portal close since it can
cause hangs and other weird behaviour if another task operates on the
same instance.

See https://bugs.python.org/issue32526.

Use an inner function / closure to properly process required arguments
at call time as is recommended in the `wrap` docs. Do async gen and
arg introspection at decorate time and raise appropriate type errors.

Tyler Goodlet 9f41297298 Timeout on remote task cancellation 
Turns out you get a bad situation if the target actor who's task you're
trying to cancel has already died (eg. from an external
`KeyboardInterrupt` or other error) and so we need to eventually bail on
the RPC request. Also don't bother closing the channel created in
`open_portal()` manually since the cancel scope should take care of all
that.

Tyler Goodlet b6cc1e8c22 More pub decorator improvements 
- when calling the async gen func provided by the user wrap it in
  `@async_generator.aclosing` to ensure correct teardown at cancel time
- expect the gen to yield a dict with topic keys and data values
- add a `packetizer` function argument to the api allowing a user
  to format the data to be published in whatever way desired
- support using the decorator without the parentheses (using default
  arguments)
- use a `wrapt` "adapter" to override the signature presented to the
  `_actor._invoke` inspection machinery
- handle the default case where `tasks` isn't provided; allow only one
  concurrent publisher task
- store task locks in an actor local variable
- add a comprehensive doc string
