funny you should say that...
Just upgraded, seeing errors from asyncio saying loop closed

yikes
That's definitely a new one

Certainly very possible

but all I know for sure is if I downgrade the pulumi python package from 0.17.28 to 0.17.26, it goes away

Where is the invoke in that code? Nothing jumps out at me...
Are there multiple loops involved?

it's the inner mechanism for a lambda package builder

Copy code
handle = self._ready.popleft()
    IndexError: pop from an empty deque
    error: an unhandled error occurred: Program exited with non-zero exit code: 1
This seems bad.

yeah
unfortunately, I haven't spent enough time in the inner guts of 
asyncio
to understand it

Is there any way to turn this into a straightforward local repro?
I'd love to dig into it

🤔 no idea, but i'll try?
my first guess is long-running tasks/futures?
it might also have to do with all the machinery that goes into process handling?

microscopic-florist-22719

08/06/2019, 6:07 PM
Yeah, I wondered about that

aside, is 
pulumi.export("value", my_async_func())
a good test stand?

Not sure what you mean by test stand
But I would expect that to work

like, will it invoke the same pertinent code paths as if i embedded the process into a resource?
m

microscopic-florist-22719

08/06/2019, 6:33 PM
Ah
Yes, I believe so
h

08/06/2019, 6:38 PM
ok, so far trivial repros aren't working
git bisect
puts the blame on Make 
pulumi.runtime.invoke
synchronous. (#3019)
so i guess that theory is lightly confirmed
(63eb7abb5949e562b20bf9fe43bac1868e730774)
I filed https://github.com/pulumi/pulumi/issues/3038 so that there's a note where other people can find that this bug exists

Thank you!

fun fact: i don't actually have to invoke deplumi to trigger the bug, just import it
those are the best bugs
