I'm interested in the segfaults issue from #91 and needed an excuse to be added as a maintainer :) Pardon the noise.

Hi! This is the friendly automated conda-forge-linting service.

I just wanted to let you know that I linted all conda-recipes in your PR (recipe) and found it was in an excellent condition.

I didn't get anywhere, but did setup a local reproducer on an old Mac I have. I did also try the shapely main branch, which will pass all tests except one if I comment out the stray import pylab in the examples (no conda-forge matplotlib yet).

can debug this more now locally.

Feel free to open a separate PR just for that :)

I did also try the shapely main branch

The main branch is basically a complete rewrite of the low-level code (no longer using ctypes), so for figuring out those segfaults for 1.8, you will need to test with the 1.8 tag or maint-1.8 branch

Did you succeed to reproduce the segfaults?

[akrherz]

Did you succeed to reproduce the segfaults?

Indeed, but no resolution yet.

Hi @akrherz @jorisvandenbossche Is there any news on that? Thanks!

XRef: This is currently blocking the migration of cartopy(https://github.com/conda-forge/cartopy-feedstock/issues/131).

[jorisvandenbossche]

Not yet. The root cause is an issue in the Python / libffi build, and that is being discussed here: https://github.com/conda-forge/python-feedstock/issues/522

[kmuehlbauer]

Thanks for the pointer, much appreciated.

Hi! This is the friendly automated conda-forge-linting service.

I was trying to look for recipes to lint for you, but it appears we have a merge conflict. Please try to merge or rebase with the base branch to resolve this conflict.

Please ping the 'conda-forge/core' team (using the @ notation in a comment) if you believe this is a bug.

Exciting times for a Friday evening, awaiting python-3.10.0-h1248fe1_3_cpython.tar.bz2 and the like to appear in repo metadata!

[xylar]

@akrherz, I restarted CI. Fingers crossed.

We're good! Thank you @akrherz, @jorisvandenbossche, @dopplershift and others for tracking this down!
