Conda-Build Dependency Compatibility Issue with API Changes in Version 24.1.0

[itamarg365]

After upgrading to conda-build version 24.1.0, we have encountered compatibility issues with certain APIs, specifically related to mambabuild.

Steps to Reproduce:

1. Upgrade conda-build to version 24.1.0.
2. Execute conda mambabuild . --no-tests
3. Observe

ImportError: cannot import name 'update_index' from 'conda_build.index' (/home/itay/.conda/envs/myvenv/lib/python3.10/site-packages/conda_build/index.py)

Additional Information:

Workaround:

Downgrade conda-build to 3.28.4

Related Issues:

Environment Information:

Operating System: macOS Sonoma
Conda Version: 4.10.3
Python Version: 3.10.13

Suggested solution:

Use update_index directly from conda-index at https://github.com/mamba-org/boa/blob/main/boa/cli/mambabuild.py#L16

Note:

I not a contributor in this repo, that why I didn't create a PR. I guess that the version change created many more API breaks in this package, and this is just one indication.
Feel free to contribute to this discussion, and let me know if there are any specific steps, code snippets, or logs that can help in resolving this issue. Thank you!

We ran into the same issue, I created a minimal example repo where it shows up in the CI.

It should be updated to use https://github.com/conda/conda-index/blob/main/conda_index/index/__init__.py#L111 or the ChannelIndex class directly as shown in https://github.com/conda/conda-index/blob/main/conda_index/cli/__init__.py , as a side effect this version of conda-index is much faster.

Added #393 and conda-forge/conda-forge-repodata-patches-feedstock#657 to mitigate the issue.
