Managing dropping python2 support
by Nathan Goldbaum May 22, 2017

May 22, 2017

Hi all, PyCon is going on right now in Portland. One of the talks today was about how IPython managed dropping support for python2 in IPython 6.0. You can watch the talk here: https://youtu.be/2DkfPzWWC2Q Some takeaways from me (all opinions my own): IPython probably did this a bit too early. Since they're relying on features in pip and setuptools that were only added a few months ago, users are unlikely to have up-to-date versions that will behave nicely. On the other hand, IPython is a big enough package that they are actually driving people to update their pip installation after hitting some breakage. We can do things now to minimize pain in the future if we do drop support for some python versions we support right now: * Define requires_python in our setup.py * Update our documentation and scripts to use "pip install ." or "pip install -e ." instead of "python setup.py install" or "develop" Nathan

List of issues blocking yt 3.4
by Nathan Goldbaum May 17, 2017

May 17, 2017

Hi all, We've come up with a final list of issues that will block the release of yt 3.4: https://github.com/yt-project/yt/issues?q=is%3Aopen+is%3Aissue+label%3Abloc… If you know of any issues that you think should be addressed before we release yt 3.4, please speak up. If you are interested in working on any of these issues, please feel free. If someone has already assigned it to themselves you may want to check with them first. If no one has been assigned an issue you're interested in fixing, feel free to issue a pull request for it. Hopefully we'll be able to get yt 3.4 out soon :) -Nathan

Issue triage hangout
by Nathan Goldbaum May 16, 2017

May 16, 2017

Hi all, Britton and I have scheduled a hangout for Wednesday at 3:00 PM central time to triage the issue list for yt in preparation for shipping yt 3.4. If you'd like to join in let me know and I'll send you an invite to the event. Optimally we'll end this hangout with a more manageable list of issues that block the release of yt 3.4 than the current list of 94 open issues. -Nathan

Hi all, I've just enabled continuous integration via Appveyor for yt-project/yt. This will allow us to continually test that yt is working on windows. Please let me know if you run into issues relayed to the Appveyor testing. -Nathan

Testing infra and github
by Kacper Kowalik May 4, 2017

May 4, 2017

Hi all! I have a couple of announcements regarding the current testing infrastructure that's integrated with GitHub: * if for some mysterious reason the test suite fails, and you're pretty sure it's not due to the incoming changes, you can trigger another build by adding a '@yt-fido test this please' comment on your PR. * docs builds for PRs are now disabled. We are blocked by: https://github.com/jenkinsci/ghprb-plugin/pull/293 Development version of docs is built and deployed just fine. As usual, if you notice something not working, please let us know. Cheers, Kacper

Issue triage and yt 3.4
by Nathan Goldbaum May 4, 2017

May 4, 2017

Hi all, Now that we're fully on github I took the opportunity today to triage our issue list. There were a number of issues that I could close immediately either because they are fixed already, were classified incorrectly as open when we imported them from bitbucket, or because there wasn't sufficient information to reproduce or understand the reported issue. That leaves us with 97 open issues. Now we need to decide which of those 97 issues should be blockers for a 3.4 release. Currently almost all of the open issues are in a new 3.4 "milestone" we can track: https://github.com/yt-project/yt/milestone/14 I've also created a bunch of labels. We can probably bikeshed about what they should be named and if we have too many: https://github.com/yt-project/yt/labels I'd like to propose that we move all the issues I've marked "new feature", "help wanted", and "wish" labels to a new 3.5 milestone. In addition, I think many of the issues marked "enhancement" can also be moved. I think it would be worthwhile to schedule a hangout sometime in the next couple weeks to determine which issues should block a 3.4 release. Let me know if you are interested in that so we can figure out a date and time. -Nathan

Github migration is complete
by Nathan Goldbaum May 3, 2017

May 3, 2017

Hi all, We just merged our first pull requests on github! We wanted to wait on doing this until the mirror bot was updated, which is now complete. If you have a commit bit, you should feel free to merge PRs that have undergone sufficient review. You can also indicate that you reviewed and approved a PR by either commenting on it or by going through the github code review interface (see https://help.github.com/articles/about-pull-request-reviews/ ). Thanks very much to everyone who helped out with this effort! So far I think it's been pretty painless (*knocks on wood*). That said, please let us know if you run into any issues (e.g. with yt setups that use a source install of yt from a mercurial repo). -Nathan

yt astro analysis
by Britton Smith May 1, 2017

May 1, 2017

Hi everyone, Now that yt development has moved to github, I want to bring up an opportunity for some smaller yt-related development projects. As some of you may know, it was decided a couple months ago that most of the code in the analysis_modules directory will be moved to various external repositories to allow them to be developed separately from the main yt codebase. The rough timeline for this is to have all analysis modules marked as deprecated by the release of yt-3.4 and fully removed (and in a separate, pip-installable repo) by yt-4.0. The initial extraction of the analysis modules has now been done and can be found here: https://github.com/yt-project/yt_astro_analysis To be clear, the analysis modules are still present in yt, but this repo contains only those modules. The revision history has also been maintained. Anyway, there are a number of small tasks that must be completed before this package becomes the replacement for yt's analysis modules. I will begin adding issues on github for all these. If anyone is interested in helping out with this, just come talk to me on the yt slack channel or feel free to just dig in and start issuing PRs. Thanks! Britton

Hi folks, For those of you who are "members" of the project on GitHub, if you are willing, please mark your status as "public." You do this by going to: https://github.com/orgs/yt-project/people finding your name, and then clicking the dropdown where it says "Private" and choosing "Public". Thanks, Matt

A few remaining bitbucket pull requests
by Nathan Goldbaum May 1, 2017

May 1, 2017

Hi all, I'm ok with porting my pull requests over, but I'd really like it if we could merge in the pull requests from Weiguang Cui: https://bitbucket.org/yt_analysis/yt/pull-requests/2534 (Gadget I/O improvements) https://bitbucket.org/yt_analysis/yt/pull-requests/2560 (docs for PR 2534) and Andrew Myers: https://bitbucket.org/yt_analysis/yt/pull-requests/2575 (support for face-centered fields in the AMRex frontend) I realize that both of these PRs are quite frontend-specific and that not everyone will feel comfortable reviewing, but it would be helpful if you could step out of your comfort zone and give it a shot. I'm personally of the opinion that both of these efforts are mergeable as-is. If others feel that we shouldn't rush these through that's ok, I'm just worried about these in particular because they've been open for a while and haven't seen sufficient code review. -Nathan

yt has moved to GitHub
by Matthew Turk April 30, 2017

April 30, 2017

Hi folks, Following up on the discussion from last month, yt has now finished moving to GitHub. We'll be working with pull request authors to transition any remaining pull requests on BitBucket to GitHub, but all of the infrastructure is now in place, including documentation, install scripts, issue tracking and continuous integration. Thanks to Nathan, Kacper, Alex, John, Britton and everyone else who worked on this transition project. https://github.com/yt-project The main repository is here: https://github.com/yt-project/yt I'd also like to thank BitBucket for many wonderful years of hosting, and note that I'm not without a bit of sadness that we've made this move. That being said, I think this is an exciting opportunity for broadening our developer base! -Matt
