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.

This PR seems to change the default python to be compiled with pydebug.

I believe it is desired that both versions be compiled: with and without the pydebug feature.

[dfroger]

Maybe I made the pull-request wrong in github, the intent was to add the code in a python-debug branch of the python-feedstock repo. (To avoid creating a new python-debug-feedstock repo, and simplify maintenance).

Doesn't seem to be possible to
pull request to a new upstream branch with GitHbub

@dfroger Thanks for putting this together, I'm excited about getting a debug build on Python on conda-forge. I went ahead and created a python-debug branch in this feedstock which you should be able to direct a pull request against. I think you may need to rerender the feedstock to get the CI services to start working.

That SO answer is outdated @dfroger . They changed this maybe a couple of months back. Just click edit near the title and it will provide the option to change the base branch.

@jjhelmus @jakirkham thanks, I changed the base branch to python-debug.

When I build the package on my machine, the package is successfully created, but then the test failed due to the feature. I tried to add the feature metapackage to the test: requires: section, but without success.

I'm going to rerender the feedstock.

[jakirkham]

So re-render is definitely needed. However, I don't think that alone will solve the issue. I think we need a new metapackage that helps us enable/disable the debug feature for Python. Though if someone has a better idea feel free to share.
