[opensuse-factory] Leap 15.2: python3 and blender 2.80
Hi Ludwig, looks like 15.2 will want to stay with Python 3.6.x, which is a bit unfortunate, since this effectively excludes Blender 2.80, which requires Python 3.7 at least. Although Blender on openSUSE is flying under the radar at the moment, Blender catches quite some interest everywhere, and it would be a pity, if this nice piece of software would be kept out on the next big step of openSUSE. Yes, 15.2 comes with Blender 2.79, but the difference between those two versions is quite significant (apart from the fact, that older openSUSE Blender builds are not feature complete..). I got a related request today already: https://devtalk.blender.org/t/blender-2-80-in-opensuse-factory-tumbleweed/ 9084/9 If you consider to include the current Blender, please note, that it will depend on a few auxiliary libraries to be feature complete (alembic, embree, OpenSubdiv and openvdb).

Any compelling reason to stay with Python 3.6? Ciao, Michael. -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org

Hello team, I've just opened jsc#PM-1482 to track "Hans-Peter's user story". in SLE-15 targeting both SP2/SP3 and notified PM.

Thanks to a magician named Stefan Brüns, we solved this problem with a patch to blender, that replaced the direct Python 3.7 API calls with some, that are available with 3.6.

Hello Hans-Peter, I just proactively opened a feature request for SLE-15 SP2/SP3, and questioned whether some customer could find a use for python-3.8, perhaps in the same scenario as you as that would in the end solve Leap's issue as well. However Ludwig just approached me that Leap found another solution, therefore it seems like it can be cancelled, unless Blender would have some noticeable performance improvements with newer python.

Thanks a lot for taking these steps proactively.
Yes, I mentioned this a few lines below (in that mail) as well. I could imagine, that there is a strong interest for a current Blender (2.81) in the SLE-15 distribution. The only hurdle is the legal approval of the Intel OpenImageDenoiser (oidn) in Factory: https://build.opensuse.org/package/requests/graphics/OpenImageDenoise But, as Stephan has mentioned today in the telegram thread, the legal review queue is stalled at the moment... Once, this one is approved, we're ready to submit Blender 2.81 to graphics, and forward it to Leap and Factory immediately.

You can (and have to) keep oidn optional (bcond) in blender, as OIDN is x86_64 with >= SSE 4.1 only. Keep it optional for all, and then switch it for x86_64 as soon as OIDN lands in TW. Blender 2.81 then can go through source and legal review in parallel. Kind regards, Stefan -- Stefan Brüns / Bergstraße 21 / 52062 Aachen home: +49 241 53809034 mobile: +49 151 50412019

It is up to the maintainer to get the package into 15.2 if needed. Upgrading the system python is out of scope for 15.2 though. If blender wants to be able to run newer versions on stable, maintained distributions, relying on core system components it needs to watch what to put as requirements. Did you talk to upstream yet? Maybe they are just not aware and the version requirement was just naive. cu Ludwig -- (o_ Ludwig Nussel //\ V_/_ http://www.suse.com/ SUSE Software Solutions Germany GmbH, GF: Felix Imendörffer HRB 247165 (AG München) -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org

Since Python is the base of the heavily used Blender Add-On ecosystem, we cannot just drop these requirements unilaterally. If we cannot ship a feature complete package, we should admit just that. That's the downside of the SLE relationship. Obviously, the only way to deal with this discrepancy correctly is packaging a private Python 3 interpreter, but that's not much fun either. And since Dave Plater doesn't trust me enough to assign co-maintainership to me, that's even less of a motivation. But we shouldn't confuse people with half-baked solutions, which harms the project as a whole in the end...

As far as I can see, blender only requires a single function from the 3.7 C API, which can be replaced by two function calls available in 3.6 (probably older). The new function is slightly faster, but that should not matter for the 2 places where it is used. Please have a look at the blender package in my home repo:

Hey Stefan, magic! If that's all, then let's go for it. Of course, this might break some Add-Ons, but since their authors doesn't code in Rust, the fall-out will be limited. What we will need is getting the dependencies into 15.2 quickly. Thanks, well done.
