Add Zarr

[matthewfeickert]

(Moving from zarr-developers/zarr-python#2935)

@d-v-b Please have a member of the Zarr team complete the missing items from the checklist to get started.

• Create an account on Anaconda Cloud
• Reply here with the link to your account (https://anaconda.org/jhamman)
• Make a new Anaconda Cloud API token with permissions described in https://scientific-python.org/specs/spec-0004/#process-for-adding-new-projects

• Save the API token as a repo GitHub Actions secret named ANACONDA_ORG_UPLOAD_TOKEN
• Direct @scientific-python/nightly-wheels-developers to a zarr nightly wheel for us to upload to create the package in the registry
• Verify that we have added you to the zarr team "Group" on https://anaconda.org/scientific-python-nightly-wheels
• Verify that we have added the package scientific-python-nightly-wheels/zarr to the zarr team "Group"

If you'd also like to use the scientific/upload-nightly-action GitHub Action please check out the action repo's README. If you need to collect wheels from different CI jobs, consider creating a new GitHub Actions workflow with logic similar to matplotlib's or Awkward's.

If you have any questions please just ask here!

I'm handling this on behalf of the zarr-python dev team.

Direct @scientific-python/nightly-wheels-developers to a zarr nightly wheel for us to upload to create the package in the registry

Can someone direct me further on this step?

Can someone direct me further on this step?

@jhamman To create the project on Anaconda.org we need a wheel to upload to seed it. So if you already have a system for nightly builds then a nightly wheel would make sense here. If not, then we can just use a wheel from the last release on PyPI, as this is just a seed wheel and can be deleted after the first nightly wheel gets uploaded successfully.

[jhamman]

We should just pull a wheel from PyPI then.

[matthewfeickert]

@jhamman Sorry about the delay. I've uploaded a wheel from PyPI to https://anaconda.org/scientific-python-nightly-wheels for you to create the project https://anaconda.org/scientific-python-nightly-wheels/zarr (it can get deleted later on). If you create API tokens you should now be able to upload nightly wheels.

Once you've done that at least once in a workflow we can close out this issue.

[matthewfeickert]

👋 @jhamman Just wanted to check in to see if you had any questions.

[matthewfeickert]

@jhamman Ping on this. Do you have any questions with regards to getting nightly wheels uploaded?

[ianhi]

Hi @matthewfeickert is it possible that the uploaded wheel expired? @jhamman reports that https://anaconda.org/scientific-python-nightly-wheels/zarr goes to a page not found

Can you clarify what the intended mechanism for creating the project is? Is there a different URL to go to to allow creation?

[matthewfeickert]

@ianhi sorry this notification got lost.

Yes, this got autoremoved given the cleanup policy

upload-nightly-action/README.md

Lines 68 to 78 in 50aa237

	## Artifact cleanup-policy at the ``scientific-python-nightly-wheels`` channel
	To avoid hosting outdated development versions, as well as to clean up space, we do have a
	default retention policy of:
	- Latest **5 versions**
	- Artifacts newer than **30 days**
	Any versions beyond these are automatically removed as part of a daily cron job run from this repository.
	Projects may have reasons to request to be added to the list exempt from this automated cleanup, however
	in that case the responsibility of cleaning-up old, unused versions fall back on the individual project.

I've reuploaded a wheel now to https://anaconda.org/scientific-python-nightly-wheels/zarr.

@ianhi should your Anaconda.org account be added as a maintainer of the group for this package?

Can you clarify what the intended mechanism for creating the project is? Is there a different URL to go to to allow creation?

Given the way that Anaconda.org works it is a little hacky in that an org maintainer needs to manually upload a wheel the first time to create the project which can then be assigned a specific maintainer. This isn't great, and is something that we've raised before (c.f. #130).

[jhamman]

thanks @matthewfeickert for the help -- I believe I've done my part including zarr-developers/zarr-python#3449

Nice. Once we verify that your CI workflow can upload then we can close this out. 👍

[jhamman]

This is working so we can close it out.
