Restore downstream tests with mambabuild

[bollwyvl]

Comment:

Both #110 and #109 are both failing on the downstreams due to conda errors like:

TEST START: /home/conda/feedstock_root/build_artifacts/pkg_cache/jupyterlab-3.5.2-pyhd8ed1ab_0.conda

Probably going to just ship without testing the downstreams, but would be good to get this back.

I've seen this too outside conda-forge. Not sure if it's a libmamba parsing error or a bad JSON file. Does it happen if you disable mambabuild?

[bollwyvl]

thanks @jaimergp, trying on #112...

[bollwyvl]

It does appear to get past that sticking point. Still have some other issues, but i think they are more easily debugged (downstream test dep drift)

[bollwyvl]

    jupyterlab_server:             2.16.5-pyhd8ed1ab_0       local      
    openapi-core:                  0.14.2-pyhd8ed1ab_0       conda-forge
    openapi-schema-validator:      0.3.4-pyhd8ed1ab_0        conda-forge
    openapi-spec-validator:        0.5.1-pyhd8ed1ab_0        conda-forge

Then

E   ImportError: cannot import name 'default_handlers' from 'openapi_spec_validator' ($PREFIX/lib/python3.11/site-packages/openapi_spec_validator/__init__.py)

[bollwyvl]

Ugh, that shouldn't be happening:

    - openapi-core >=0.14.2,<0.15.0
    - openapi-spec-validator >=0.4.0,<0.6

I think i remember that from the pre-default-mambabuild days.

[bollwyvl]

Reopening as it doesn't use mambabuild, and it would be ideal to get back to that.
