i386 package still not published?

[Ernst Persson]

This rebuild was supposed to build it for i386,
https://launchpad.net/ubuntu/+source/spirv-llvm-translator-15/15.0.0-1ubuntu2
and according to launchpad the binaries were created.. but I don't think they actually made it to the archive?

Thank you for your bug report. Do you need it for anything? I don't think we are publishing record for binaries and I don't remember why I did the rebuild but it was probably to unblock proposed migration. It is likely that the build was published but got removed later because whatever made it necessary stopped to depends on it. If there is a need for the i386 build and no rdepends to pull it in then we need to explicitly include it in the whitelist

Hi! I ran into it when building Mesa master:

https://launchpadlibrarian.net/673411775/buildlog_ubuntu-lunar-i386.mesa_23.2.0~git2306212059.df6749ed569~l~mesaaco4_BUILDING.txt.gz

Stopped working after the 16:th now, a week ago.

I haven't really looked into the details, but then I saw this strange state so I thought I would report it.

But perhaps I should really just disable CLC for i386 in the build or something like that instead....

[Sebastien Bacher (seb128)]

Subscribing Steve who probably has insight on why the binary vanished

[Steve Langasek (vorlon)]

https://launchpad.net/ubuntu/lunar/i386/libllvmspirvlib15 shows it was deleted with a generic removal comment as part of the cleanup before the lunar release. So the answer is, effectively, nothing in the seed depended on it to hold it in.

And I had dropped the manual override from the script that seeds i386 packages on March 13, with the comment "Drop finished bootstraps" which implies that at the time, removing it from the script did not change the output and result in any packages dropped, so it remained seeded.

Seb, the history shows it was also you that originally seeded it for the new mesa version; but it's apparently not used by current mesa in the archive?

[Sebastien Bacher (seb128)]

Ok, so it was a new depends which went away with the change in https://launchpad.net/ubuntu/+source/mesa/22.3.6-1ubuntu1

rules: Drop i386 from RUSTICL_ARCHS.

it is a requirement now in upstream git even without that option. I've added the package back to the whitelist to allow ppa builds until we get a newer mesa version uploaded to the archive

[Sebastien Bacher (seb128)]

hum, spirv-llvm-translator-15 fails to build on amd64 in mantic :-/

https://bugs.launchpad.net/ubuntu/+source/spirv-llvm-translator-15/15.0.0-1ubuntu3/+build/26341721

TEST 'LLVM_SPIRV :: GroupAndSubgroupInstructions.spvasm' FAILED

[Sebastien Bacher (seb128)]

The build issue should be fixed in https://gitlab.freedesktop.org/mesa/piglit/-/merge_requests/821 upstream, I've submitted a bug to Debian asking for that fix to be applied to the package

[Ernst Persson (ernstp)]

Add spirv-llvm-translator-16 to the whitelist also?

[Steve Langasek (vorlon)]

> Add spirv-llvm-translator-16 to the whitelist also?

Why is it needed?

[Ernst Persson (ernstp)]

> Why is it needed?

it seems logical to continue forward? :-)

but you're saying I can mix spriv-llvm-translator-15 with llvm-16 in a mesa build etc... ?

[Steve Langasek (vorlon)]

> but you're saying I can mix spriv-llvm-translator-15 with llvm-16 in a mesa build etc... ?

I'm asking why it is currently needed. All whitelist additions should include a rationale. There has been no other mention of llvm-16 in this thread.

[Sebastien Bacher (seb128)]

I guess a rational could be 'allow to build mesa with llvm-16 for testing in a ppa' ... Ernst, is that what you are after?

[Ernst Persson (ernstp)]

Right right, I see what you're after. :-)

Well as a preparation for the llvm-16 migration for mesa I want to build with that in my PPA yes.
llvm-16 is already whitelisted for i386, and spriv-llvm-translator-16 exists in mantic but is amd64 only.
So it would be a weird mismatch to use spirv-16 + llvm-16 for amd64 but then spirv-15 + llvm-16 for i386.

[Steve Langasek (vorlon)]

ok, whitelisted spirv-llvm-translator-16. https://launchpad.net/ubuntu/+source/spirv-llvm-translator-16/16.0.0-2ubuntu1/+build/26384605

[Ernst Persson (ernstp)]

Don't forget to fix the build issue:

https://launchpad.net/ubuntu/+source/spirv-llvm-translator-15/15.0.0-1ubuntu3

[Ernst Persson (ernstp)]

Is is possible for me to see these whitelists somewhere? I have search quite a lot but haven't been able to find it...

Preferably per release, because I get different results on different releases now... ?

The text of the seeds (per-release) is visible at e.g.:

  https://ubuntu-archive-team.ubuntu.com/seeds/i386.mantic/i386

The output of germinate which shows what package dependencies are included
and why is:

  https://ubuntu-archive-team.ubuntu.com/germinate-output/i386.mantic/all

And the record of the packageset, which is what is actually applied in
Launchpad (and includes those packages that have to be hard-coded outside of
the seed because they don't exist in the Ubuntu archive on that series and
therefore germinate cannot act on them) is:

  https://ubuntu-archive-team.ubuntu.com/packagesets/mantic/i386-whitelist

[Ernst Persson (ernstp)]

So is it possible to enable me to build a i386 llvm-spriv in Lunar and Jammy in my PPA... ?

The whitelists had not been updated for those series. They have been now.

[Ernst Persson (ernstp)]

Mantic, Lunar and Jammy now works with LLVM 16 + LLVM Spirv 16! https://launchpad.net/~ernstp/+archive/ubuntu/mesaaco

[Oibaf (oibaf)]

piglit is now fixed.
Please retry building amd64 of spirv-llvm-translator-15, it should succeed.
Thanks

[Sebastien Bacher (seb128)]

In fact the issue is similar but spirv-llvm-translators doesn't build-depends on piglit so that fix isn't going to resolve the build problem...

[Oibaf (oibaf)]

I built it in my PPA, and it builds OK:
https://launchpad.net/~oibaf/+archive/ubuntu/graphics-drivers/+packages?field.name_filter=spirv-llvm-translator-15&field.status_filter=published&field.series_filter=mantic

Someone with the privilege may try to click on "Retry this build" here and see what happens:
https://launchpad.net/ubuntu/+source/spirv-llvm-translator-15/15.0.0-1ubuntu3/+build/26341721

[Sebastien Bacher (seb128)]

Retried but it failed
https://launchpad.net/ubuntu/+source/spirv-llvm-translator-15/15.0.0-1ubuntu3/+build/26341721

The difference is that your ppa is configured to build without mantic-proposed so it doesn't get the updated spirv-tools version which is creating the issue

[Oibaf (oibaf)]

Fixed in 15.0.0-4.
