theelous3/multio

A unifying library for curio and trio, supporting both async libs for great good.

multio's Issues

make trio_spawn "better"

the spawn semantics are "weird"

trio dependency version is insufficient

since it's using open_memory_channel, etc.

setup.py: trio>=0.2.0

tag releases

Please tag the previous and future releases of this software. Sometimes the commit messages make it apparent, but sometimes they don't. Using tags makes it unambiguous, and makes things easier on distro packagers like myself.

tag 0.2.5

0.2.5 is on PyPI, but there's no tag in GitHub.

tests fail with pytest 3.7.0+

I noticed that the tests for this project pass with pytest 3.6.4, but fail with 3.7.0 or higher.

https://gist.github.com/carlwgeorge/26a07a6c6b99cb6bfb3530668eafe5b9

I'm not sure what changed in 3.7.0 to cause this. Travis appears to be preinstalling pytest 3.3.0, so it's not affected yet.

multio.init()

Obviously a stupid error of my part, but from a user perspective I think it would be nice if, in addition to strings, multio.init() also accepted a module.

import curio
import multio
multio.init(curio)   # This throws a KeyError

add license

Update travis config

See config reference here: #5

@DavidJLindley this be your domain

Also support asyncio ?

Possible values are <dict_keys(['curio', 'trio'])>, not <asyncio>

Any specific reason to not allow asyncio there ?

Support creating an appropriate SSLContext for use with open_connection

One can pass a curio.ssl.SSLContext when using multio.open_connection, but this requires using curio.

Uses a CapacityLimiter on trio instead of a Semaphore

Those two are not identical:

import trio

async def main():
	c = trio.Semaphore(10)
	async with c:
		print('one in')
		async with c:
			print('two in')

trio.run(main)

one in
two in

but:

import trio


async def main():
	c = trio.CapacityLimiter(10)
	async with c:
		print('one in')
		async with c:
			print('two in')


trio.run(main)

one in
RuntimeError: this borrower is already holding one of this CapacityLimiter's tokens

This means that I cannot open two connections in the same task https://github.com/Fuyukai/riopg.

Why 3.6.x restrict?

Why did we restrict to 3.6.x and up?

trio currently supports >=3.5.2, and curio doesn't completely shit the bed. Also, it broke my asks tests (it also broke multio's tests)

I reverted it for now.

Use sniffio

How about multio makes multio.init optional, and uses sniffio to initialize itself? I suppose we'd have to make curio support sniffio first.

Possibly, init could be removed completely.

Missing trio.Queue

trio.Queue has been deprecated in Trio 0.9.0 and removed in Trio 0.11.0, but multio tries to use it:

multio/multio/__init__.py

Line 466 in b6b6251

lib.Queue = trio.Queue
