Description

  • uvloop version: 0.9.0
  • Python version: 3.6.1
  • Platform: UNIX
  • Can you reproduce the bug with PYTHONASYNCIODEBUG in env?: n.a.

Hi there,

I'm facing the same problem encountered in CPython issue #414. Since the patch (see issue #428) is not upstreamed in asyncio yet, I was wondering if there is any progess on this in uvloop.
I've tested that behavior with the 0.9.0 version and it seems to be still blocking.

@1st1, have you planned to fix this? Do you need help at some point? (I was working with @martiusweb on the codebase which led to those issues)

Research direction

Start with the loop.subprocess_shell() and loop.subprocess_exec() entry points, then review the linked CPython issue #414 and patch discussion in issue #428. Reproduce the reported blocking behavior on the stated UNIX and Python versions; done means both subprocess methods no longer block as described.
