Hi all,
A couple people have mentioned to me recently (in IRC and over email) that the stable branch is missing some fixes for FLASH and Enzo data. I'd like to start a discussion on wrapping up the dev cycle and moving for a 2.4 release. The showpoint of this release I believe will be improvements to volume rendering; more on that below.
Here are the open, targeted bugs for 2.4:
https://bitbucket.org/yt_analysis/yt/issues?status=new&status=open&milestone=2.4
These touch on a few major areas:
* Minor improvements to reason and reason widgets: Adding vectors, layers (which should get postponed) a volume rendering widget (should get postponed) and a file open dialog (Nathan had been working a bit on that.) * FLASH updates to make it more user friendly: John Z and I had a brainstorming session after I spoke to some FLASH users last week, and I filled out tickets to try to address any remaining weak points. * Time Series updates: Nathan has made a few suggestions, and I'm going to implement them. I like where Time Series is going! * Volume rendering refactor (Sam, if you have a few minutes, could you give an update on what that includes and what it provides? This could be a great centerpiece of 2.4!) * Rockstar integration is incomplete and undocumented, but that may also be postponed.
There are also a few bugs that need to be addressed:
* MPI attributes now break pickling in some cases; I will address this * Ghost zone issues seem to be everywhere, as corner cases keep coming up. John W and I have spoken about this and we have an idea for how to fix it moving forward. * Quadproj scales poorly, but that'll be a bit of a tricky piece of work.
Does anyone have any comments or ideas about these bugs, or want to tackle any of them? Are there any other concerns, or thoughts on this?
How would aiming to release in a month from now sound? April 16 is a Monday, which would be a good day for a release.
We totally didn't make April 16! There's quite a lot of work to do still, and I think with conference schedules and other obligations, it's probably not reasonable to expect we'll be finished in the near future. While a strict release schedule is not necessarily crucial, I think a more reasonable estimate is actually mid-June. This will allow much better testing of things like threaded volume rendering (and for the next release of Cython, which may be a dependency) and time series and quad proj in parallel. As to the list above: * Sam came up with a great idea for scaling QuadProj, which still needs to be implemented. (I may do this.) * FLASH data has gotten a shot in the arm with the attribute processing. * The ghost zones change has been reverted. * Chris Moody is taking a look at Rockstar, but I think a blocker is that Rockstar doesn't support multiple masses of particles. * Time series is now implicitly parallel, and attributes can be accessed nicely. -Matt
