eventlet support about pytest-xdist HOT 13 CLOSED

Hmmm, I think the problem here is:

1. There was a typo in what @aschmolck was trying: exemodel=eventlet instead of execmodel=eventlet.
2. pytest_xdist doesn't complain when the argument for execnet is bogus

py.test --tx '2*popen//execmodel=eventlet' --dist load runs the example above in ~4 seconds for me...

from pytest-xdist.

P.S. This is probably the same issue as #61 but the above should make it easy to reproduce.

from pytest-xdist.

We're running into this same issue — has anyone found a workaround?

from pytest-xdist.

with recent execnet you can tell it to use a eventlet backend

from pytest-xdist.

Here's the docs on how to configure exenet to use eventlet. Closing this for now, if anybody still has questions please ask and we can reopen this.

@nicoddemus Could you maybe show how to run my minimal example above without hanging?

If I change the final line of my example from py.test -n 2 to

py.test -n 2 --tx popen//execmodel=eventlet

it still hangs as before. I seem to have the latest version of execnet installed (1.4.1).

from pytest-xdist.

i think it should be --tx 2*popen//execmodel=eventlet

from pytest-xdist.

@RonnyPfannschmidt thanks, this does indeed not hang anymore. On the other hand, it doesn't seem to result in any parallelism either. :(

use --dist load?

from pytest-xdist.

Hangs for me. Does it work for you? Pasting the snippet I posted above literally into a terminal should work, if you do have eventlet and pytest_xdist installed (e.g. via pip install eventlet==0.19.0 pytest_xdist==1.14 pytest).

i see, i currently cant test myself, im not sure what is going wrong and what part is being conflicted

from pytest-xdist.

Would it be possible to re-open this?

from pytest-xdist.

i see, thanks
