Glf deadlock on Windows 7, 10, and macOS

[meshula]

Hi there, I wanted to report an issue spotted over in the usd-build-club repo.

vfxpro99/usd-build-club#7

I've done a build locally myself and confirmed that

from pxr import Glf

[edited]

indeed deadlocks.

Issue 8 over there is probably the same thing.

vfxpro99/usd-build-club#8

Since it's reported on mac and Windows, it's happening on both the dev, and dev_win_ip branches.

Do you mean from pxr import Glf?

[meshula]

yes, that's what I meant (corrected)

On macOS, the issue was that tbbmalloc wasn't part of the prerequisites build. Making sure tbbmalloc is correctly in the path resolves it. Windows not resolved.

Filed as internal issue #140477.

It's OpenImageIO deadlocking.

sha 0b5df2944e0b772af88efa7180ff6e7c88804908 in OpenImageIO is prior to Larry's rewrite of the OIIO thread pool logic, and does not deadlock. Please feel free to close this issue.
