Starcraft Clinic 2024-Aug-16

mr_cal · August 13, 2024, 2:40pm

The next edition of the Starcraft Clinics is 2024-08-16T14:00:00Z! Come chat and get support for Snapcraft, Charmcraft, Rockcraft, or the Craft libraries in general.

You can join via Google Meet.

The last clinic primarly focused on the ideas for managing SDK snaps for QT and KDE. See discussion notes here: Keeping the sdks at par with the runtime snaps - #3 by mr_cal

If you want to discuss any topics other than starcraft applications themselves, reply here in advance so we can invite the correct parties. For example, if you have snapd/runtime questions, we can invite someone from the snapd team.

Hi @alan_g @Saviq can you join in this upcoming clinic? Would like to discuss about that version mismatch issue.

Saviq · August 14, 2024, 9:04am

Sure, I’ll be there.

Meeting Summary

Remote Build

@Saviq raised a bug on launchpad, where snaps fail to build if platforms != recipe.architectures
Bug #2077005 “Snap builds: ('<arch>' is not a supported platfor...” : Bugs : Launchpad itself

Mesa

@Saviq and @soumyaDghosh discussed compatibility across builds of the mesa-2404 snap. The discussion is continuing in https://matrix.to/#/!cniCqhKpzVvOBMHAVt:matrix.org/$_vwok1rwE9bJFHnoOp6lvN6b5xpTnKHyuuLCEE34lTM

dotnet snap

Themistoklis from SaaS was looking for guidance on a dotnet snap, @lengau volunteered to help
There is some good information in this presentation: https://build.microsoft.com/en-US/sessions/fe58e8ce-6a0d-42d9-911f-9ebfe44d6dad?source=partnerdetail (start at 13:20)

Snapcraft 7 and riscv64

Discussion on snapcraft 7 failing to build on riscv64
Created a new issue: Fix Snapcraft 7 builds on riscv64 · Issue #4980 · canonical/snapcraft · GitHub

Kernel plugin, foreign architectures

There were some changes with the pydantic 2 and craft-parts 2.0 with the plugin properties and using deb architectures
Waiting on [Investigate] support foreign architectures · Issue #104 · canonical/craft-archives · GitHub
- GitHub - canonical/iot-field-kernel-snap at 24-riscv64-nezha is a good reference for this issue

Organize failures

@mr_cal needs to see if Organizing files fails if equivalent file already exists · Issue #673 · canonical/craft-parts · GitHub is still occurring since fix(sequencer): rerun steps only if explicitly requested by cmatsuoka · Pull Request #727 · canonical/craft-parts · GitHub has landed

Detecting changes in local sources

@dilyn brought up that renaming a local file does not trigger a re-pull or a re-build
We need a good solution for monitoring file changes in local sources

Thanks all for joining, see you next time!

Thanks a lot @mr_cal for keeping these records. It was really great to discuss with.

Saviq · August 17, 2024, 5:28am

The TL;DR is that:

ffmpeg-2404 included a (newer) libvulkan.so.1 built against newer Mesa, which resulted in:
```
DRI driver not from this Mesa build ('24.0.5-1ubuntu1' vs '24.0.9-0ubuntu0.1')
```
as the “contract” between gpu-2404 providers and consumers is Ubuntu 24.04 compatibility, there’s no way to update only a subset of it, if it makes runtime checks on the exact version
@soumyaDghosh is trying to make things slightly better in a pull request - but there will always be a risk of mismatch

soumyaDghosh · August 17, 2024, 5:49am

A small correction, it’s with ffmpeg-2404, because that’s where the new gpu provider is used.

I have given you a gift here.

I have also given you several other gifts Mostly to do with the kernel plugin, which I will continue to do until I believe it is ready to be merged
