Switching from Nose to Pytest
by Coughlin, Jared W 20 Dec '19

20 Dec '19

Hello! I've been working on a PR (https://github.com/yt-project/yt/pull/2286) that converts yt's testing framework from nose to pytest. I believe that it's mostly ready to go, so I was writing to see what everyone's thoughts on this change are, if there is any feedback on my implementation, and if anyone would be willing to help review it, since there are quite a few changes. Thanks, and have a good weekend! -Jared

weekly PR triage
by Matthew Turk 24 Oct '19

24 Oct '19

Hi folks, We used to have a weekly PR triage meeting, but then, we stopped having one! I have re-created one, set up for 9:30AM Central time on Fridays for the next couple weeks. They worked really well while we did them. I've also left it be a bit long so that if there's any non-PR-triage work we can or should do, we can do that too. I know this isn't ideal for West Coast folks, but I'd be happy to set up another one as well. Looking forward to seeing you! The invitation is copied below, and there's a link to a URL that will add it to your calendar. I'll try (but will likely forget) to send out reminders. Best, Matt Matthew Turk is inviting you to a scheduled Zoom meeting. Topic: yt PR triage and co-working Time: Sep 20, 2019 09:30 AM Central Time (US and Canada) Every week on Fri, until Nov 1, 2019, 7 occurrence(s) Sep 20, 2019 09:30 AM Sep 27, 2019 09:30 AM Oct 4, 2019 09:30 AM Oct 11, 2019 09:30 AM Oct 18, 2019 09:30 AM Oct 25, 2019 09:30 AM Nov 1, 2019 09:30 AM Please download and import the following iCalendar (.ics) files to your calendar system.

Update on yt governance documents/structure
by Madicken Munk 23 Oct '19

23 Oct '19

Hi yt-dev! As many of you know, the yt-project has been growing and evolving over the past several years (to new domains, to new datasets, to support new packages, etc.). To accompany that growth, we'd like to take the opportunity to update our governance structure. We've been working on updating our governance model for the yt project and I've submitted two companion PRs with drafts of this updated governance: https://github.com/yt-project/governance/pull/1 and https://github.com/yt-project/ytep/pull/7 Our existing governance structure is located at https://ytep.readthedocs.io/en/master/YTEPs/YTEP-1776.html The first PR is to a new governance repository, where our governance documentation will live separately from the YTEPs. This will allow us to maintain and minorly update our governance without having to update YTEP. The second PR is to the YTEP repository and generally outlines the core values and ideas we want our governance structure to reflect. Hopefully all of the things I've listed in the YTEP are reflected in the governance docs. As members of the community, I'd like to solicit feedback from all of you about these governance documents. Do these reflect our community values? Should we add anything? Do you feel everything is clear? Is this too much governance for our community right now? Is there something that's missing? Feel free to reply here or comment on the pull requests! Our governance will be better with your feedback. Madicken PS - I tried to build in a mentorship structure into our maintainer structure to help with onboarding new maintainers. I'd especially like to know if you all think this would be valuable to you or if it is adding unnecessary constraints to our community.

answer testing for yt-4.0 merge into master
by Matthew Turk 07 Oct '19

07 Oct '19

Hi folks, I posted this as a comment on #2172, but I wanted to note it here. Right now the holdup for merging yt-4 into master is the answer testing. We actually would not expect the answers to be the same between the two (at the very least because the ordering of values will be different) so we need to do some kind of manually inspection. My plan for addressing answer testing differences, which I will start by doing manually: * All grid and octree data should have either the same, or justifiably different answers. In my view, "justifiably different" includes unit changes, and also includes changes as a result of particles being selected on edges of grid boundaries. These will be documented. (See #2195 ) * Results for all data selections in SPH and particle datasets should be identical in count and values, although the order will likely be different. To address this, we will have a "sorting order" field that is the morton index of the particles, and the values will be sorted and compared. This should help to identify situations where different numbers of particles are being selected (typically they should not be, except for situations related to smoothing length.) * Manual inspection of visualizations that avoid meshing in 4.0 and that utilize meshing in 3.x. I believe this should cover most of the cases, and will take to the next step of verification. To conduct these tests, I'm going to work on a script that outputs the appropriate values into an HDF5 file, and then compare the results for both. This will be somewhat distinct from the answer testing and designed for ease of exploration. Once I have a system prepared for this, I will post back here, and I will likely put the results online to view. -Matt
