Needs conda-forge/tzdata-feedstock#1
Closes #392

[conda-forge-linter]

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.

[mingwandroid]

Yes, I developed a replacements thing recently just to get away from having to bash script or manually edit so much brittle stuff. Here's an example of it: https://github.com/AnacondaRecipes/qt-feedstock/blob/master/recipe/conda_build_config.yaml#L9-L28

[ocefpaf]

I thought that the idea was to avoid the python package and force Python to find the tzdata noarch generic, no?

[ocefpaf]

🎉

[ocefpaf]

@mingwandroid any final thoughts/consideration? Are we good to merge?

[isuruf]

@mingwandroid, I removed the hand edited sysconfigdata files as they were outdated and added code to generate the sysconfigdata for the system gcc and the conda compiler. Let me know if you are okay with that.

[mingwandroid]

I say go for it (then take cover)

[mingwandroid]

Oh one quick thing:

case "$target_Platform" in

does the case of the P matter here?

[isuruf]

yes, it does. fixed in f988bc8

[isuruf]

Thanks @mingwandroid and @ocefpaf

[ocefpaf]

And you @isuruf! This one really took a village to get done!

[ocefpaf]

Also thanks to @pganssle for guiding us with the tzdata package and @mbargull for creating it!

[mingwandroid]

Great to see this land. From my perspective, it's the first time I've worked on a big update to Python within conda-forge in the first instance. That's of course the best way, esp. for the important packages.

It was a huge effort for many of us and of course its completion brings a whole bunch of other stuff to build, but with conda-forge's excellent tooling (and GitHub) that's not too scary a prospect.

For now, I must get 3.9.0 on defaults ASAP (I added tzdata and python-tzdata already - do we need both still? I got a bit confused around that bit!). I'll base it on the recipe here, and rebase the anaconda advertising patch to happen last (this makes patch rebasing easier). On that note, we should also talk about adopting the anaconda advertising method for conda-forge too instead of the conda-forge branding stuff, it is more reliable and involves less file IO at interepreter launch time, pinging @jjhelmus on the reliability matter). CMake detects our tools now (thanks KitWare!) and will increasingly do so so having some more uniformity around this stuff would be good.

Keep on keeping on conda-forge.

To build python we only need tzdata. We also offer python-tzdata b/c some packages may want to use it. They do share the same zoneinfo data now.

Sure. I don't really know what that entails but it sounds like something we could do.

Yep, like Felipe said, it makes sense to have both. python-tzdata isn't really important for our Python distribution, because with tzdata we should ship everything zoneinfo needs. But we'll probably see (few?) other packages that may add python-tzdata as a dependency in the future.

Keep on keeping on conda-forge.

Same here, agreed! Best thing would probably be to just open a PR whenever you're ready and discuss details there.

Hello,

I'm running on a 64-Bit Windows 10 v. 1909

I just tried to install python 3.9.0 in a new empty Conda Env (named new2).
However, I always get the following error:

[mingwandroid]

You should use: conda config --set add_pip_as_python_dependency false

.. at least until pip is rebuilt.

(everyone should use this, always IMHO)

@mingwandroid Thank you. That solved my problem.
