This fixes an issue that came up starting with numpy 1.21 (segmentation faults in certain cases where a C++ array was exposed to Python), but was patched in numpy. numpy 2 removed the fix so the solution is to fix Boost. More details are described in this issue (https://github.com/boostorg/python/issues/376). The upstream PR in Boost is here (https://github.com/boostorg/python/pull/443).

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 tested the patched Boost libraries with the code that I maintain with numpy versions 1.19 to 2.0, and the tests pass with the patched libraries. We have numerical arrays exposed to Python using Boost and we get segmentation faults without the fix (numpy 2 migrator for cctbx-base package)

I ran the tests with GitHub Actions and tested linux, Windows, and macOS (Intel and Apple Silicon). The patched packages for Boost and cctbx-base are on my testing channel (https://anaconda.org/cctbx-dev).

numpy	Python	Test results
1.19	3.9	https://github.com/cctbx/cctbx/actions/runs/10015271694
1.20	3.9	https://github.com/cctbx/cctbx/actions/runs/10015685246

1.25	3.9, 3.10, 3.11	https://github.com/cctbx/cctbx/actions/runs/10020687839
1.26	3.9, 3.10, 3.11, 3.12	https://github.com/cctbx/cctbx/actions/runs/10021771130
2.0	3.9, 3.10, 3.11, 3.12	https://github.com/cctbx/cctbx/actions/runs/10023084470

There is a Test environment info step that lists the packages in the testing environment and a Run subset of tests step for the actual tests that are run.

My concern with run_constrained is that there is probably code that is wrapped with Boost.Python, but does not go through this particular code path. If they have numpy in their environment, it would be updated unnecessarily. Considering that there have not been any other issues raised about this seems to indicate that this code path is not too common.

I can add the run_constrained option if always updating numpy is okay. Thoughts? Thanks!

What are the next steps here?

Rebase, or at least fix the conflict.

Thanks for the extensive testing. IIUC, things work with numpy 1.19 (which is the absolute lowest bound that any package produced here would require anyway), so then we don't need to add anything else here.

That should fix the conflict

Checking in to see if anything else needs to be done. Thanks!
