Failure in conda build process, missing noarch/repodata.json

[marcelotrevisani]

I have seeing some errors in conda-forge after the new conda-build release.

The error is regarding a missing noarch/repodata.json.

It's possible to see the conda version and also the process in this link:

There are at least 3 packages which are failing in conda-forge, like:
conda-forge/staged-recipes#6587
conda-forge/staged-recipes#6623
conda-forge/staged-recipes#6624

And there is an open issue in conda-forge regarding that:
conda-forge/staged-recipes#6587

Quoting @mbargull

@marcelotrevisani, I didn't take an in depth look at it, but it's possibly a bug introduced with the index changes in conda-build 3.14. If you don't find any other explanation, please raise a conda-build issue.

It could be a problem in the new conda index, but conda index is not used by anaconda.org at all. This seems potentially like an anaconda.org problem, which may instead be tied to a recent re-deployment that we had to do because disks were full.

[mbargull]

It's not anaconda.org, it's not finding the local build channel. (Though I have no idea why this gives an HTTP error 😕.)

[msarahan]

I looked at the error more, and it's definitely a conda-build problem. The 404 is happening on the local channel. I'll take a look at this ASAP.

[msarahan]

This is happening because update_index was changed to operate on whole channels, not on subdirs. https://github.com/conda-forge/staged-recipes/blob/master/.ci_support/build_all.py#L34

We probably need to fix conda-smithy in the long-term, but for the short-term, I'll put in a fix to conda-build and a deprecation warning.

Sorry for the unintentional breaking change.

Hi @msarahan this is still failing with conda-build 3.14.1

[msarahan]

hmmm.... it is taking the new code path I put in:

The update_index function has changed to index all subdirs at once.  You're pointing it at a single subdir.  Please update your code to point it at the channel root, rather than a subdir.

I'll have to try again.

Thanks @msarahan to fix this! :)
