The Matrix/IRC bridge is down, so we didn't have the meetbot for today's
meeting.
We discussed 3 things:
1) F37 flatpak runtime retirement
2) Automatic man page compression for flatpak builds is fixed
3) Progress with switching from Modular builds to regular koji builds
Owen has done some nice work with changing the flatpak build infra to
not rely on MBS (Modular Build System), but it still needs landing in
prod to test everything together. If we can't land it before the infra
freeze in two weeks, we'll likely need to postpone the whole thing for F40.
The full meeting log follows down below.
====================================================================
8/7/2023, 4:01:44 PM - Kalev Lember: Welcome to our bi-weekly Flatpak
SIG meeting.
8/7/2023, 4:01:51 PM - travier (@siosm:matrix.org) joined the room
8/7/2023, 4:01:58 PM - travier (@siosm:matrix.org): 👋
8/7/2023, 4:02:15 PM - Kalev Lember: We don't have the irc bridge
operational so it's going to be a bit rough. I'll try to hand-craft
notes afterwards.
8/7/2023, 4:02:37 PM - Kalev Lember: (We don't have the irc meeting bot,
that's why the hand crafting meeting notes)
8/7/2023, 4:03:14 PM - Owen Taylor: Sounds fine - thanlsl for doing that!
8/7/2023, 4:03:19 PM - Kalev Lember: OK, so I have some random updates
and I then maybe we could let Owen give a quick update about the new
build system status?
8/7/2023, 4:03:23 PM - Kalev Lember: Great :)
8/7/2023, 4:04:09 PM - Kalev Lember: First of all, I think we should be
done with updating everything to the F38 runtime, and there is nothing
left on the F37 one. 🚀
8/7/2023, 4:04:57 PM - Kalev Lember: So I went ahead and pushed the
thing that are needed to mark the F37 runtime as EOL. The EOL'ing update
is still in testing so if anyone finds something that still uses the F37
runtime we can hold it back still.
8/7/2023, 4:05:14 PM - Kalev Lember:
https://bodhi.fedoraproject.org/updates/FEDORA-FLATPAK-2023-4f477c1954
8/7/2023, 4:05:50 PM - Kalev Lember: Second, I looked into the man page
compression issue where we didn't get automatic man page gzip
compression for flatpak /app builds
8/7/2023, 4:06:35 PM - Kalev Lember: It turned out to be a fairly
trivial fix and hopefully we won't need to go and change all the
packages any more for flatpak support :)
https://src.fedoraproject.org/rpms/flatpak-rpm-macros/c/237fc133a30759a1f75a9b0fd4b577a9c5f3190c?branch=rawhide
8/7/2023, 4:06:44 PM - Kalev Lember: I can't believe we didn't try to
figure it out earlier :)
8/7/2023, 4:08:05 PM - Owen Taylor: Hmm ..... I think I assumed it would
require upstream RPM changes - or maybe it even did
8/7/2023, 4:08:33 PM - Kalev Lember: Yeah, I guess I too thought it
would be complicated :)
8/7/2023, 4:08:40 PM - Kalev Lember: Anyway, that was my updates. Owen,
the floor is all yours!
8/7/2023, 4:11:12 PM - Owen Taylor: Hmmm ... I guess the basic status is
"orange" for F40 - I have things more or less fully working, but the
infrastructure isn't there, and we're two weeks off of the beta
infrastructure freeze
8/7/2023, 4:12:00 PM - Kalev Lember: should we postpone it to F40 and
keep on using mbs for F39?
8/7/2023, 4:13:15 PM - Owen Taylor: Let's wait just a bit before making
that call. After all, we wouldn't typically start working on F39
Flatpaks until around the beta And maybe I can get it done.
8/7/2023, 4:13:34 PM - Owen Taylor: What is needed to get it done:
8/7/2023, 4:13:42 PM - Kalev Lember: Makes sense to me.
8/7/2023, 4:14:46 PM - Owen Taylor: A) Fix a couple of remaining issues
in flatpak-module-tools and koji-flatpaks - the top issues are that I
don't have arch-specific package support and release numbering is still
wonky
8/7/2023, 4:15:03 PM - Owen Taylor: B) Get koji-flatpak packaged in Fedora
8/7/2023, 4:15:18 PM - Owen Taylor: C) Get it onto the staging builders
... test it out there in some fashion
8/7/2023, 4:15:24 PM - Owen Taylor: D) Push it live
8/7/2023, 4:15:35 PM - Owen Taylor: That's more-or-less the tasks.
8/7/2023, 4:16:20 PM - Kalev Lember: Oh, about release number - I was
wondering if you could do it in a way that's similar to eln, where
there's .eln127, .eln128 etc suffixes to dist tag?
8/7/2023, 4:16:34 PM - Kalev Lember: That would allow us to easily
rebuild things if we get maybe ordering wrong
8/7/2023, 4:17:21 PM - Owen Taylor:
https://gitlab.com/fedora/sigs/flatpak/fedora-flatpaks/-/issues/16 is
the tracking bug for release numbering
8/7/2023, 4:17:55 PM - Kalev Lember: Like, someone pushes a rebuild for
a new library to dist-git, we rebuild it for /app but get the order
wrong, so it's still rebuilt against the old library.
8/7/2023, 4:18:01 PM - Owen Taylor: My initial proposal was
firefox-flatpak-112.0.2-1 where we use a different koji name
8/7/2023, 4:18:11 PM - Kalev Lember: eln would just bump distro version
and get a new, higher dist tag in that case
8/7/2023, 4:19:02 PM - Owen Taylor: Ah, yeah, I'm actually talking about
the release tag for *flatpaks* not the rebuilt RPMs
8/7/2023, 4:19:09 PM - Kalev Lember: Ahh right!
8/7/2023, 4:19:56 PM - Kalev Lember: Yeah, I'm talking about rebuilt
rpms. I'm worried that we'll get the order wrong quite often because we
don't have tooling to match them to regular package builds.
8/7/2023, 4:20:31 PM - Owen Taylor: The new flatpak-module-tools
actually has ordering tooling
8/7/2023, 4:20:54 PM - Owen Taylor: Right now, it's only hooked up for
local builds, but should appply to Koji builds too
8/7/2023, 4:21:01 PM - Kalev Lember: Ohh, interesting.
8/7/2023, 4:22:19 PM - Kalev Lember: Anyway, I think I'm digressing here
:) We can easily change the dist tag stuff afterwards as well, it's
definitely not a blocker I think.
8/7/2023, 4:22:25 PM - Owen Taylor: I think for rebuilt RPMs, I'd like
to try just starting with changing the dist tag but keeping the
numbering the same - it might occasionally*rrequire a bump-and-rebuilt
in dist-git, but I'm hopeful (perhaps wrongly?) that that won't be common.
8/7/2023, 4:23:24 PM - Kalev Lember: Sure, and it's easy enough to
change the dist macro in the tag later if needed.
8/7/2023, 4:24:01 PM - Owen Taylor: Getting back to Flatpak release
numbering, so, I think there was a preference here to not do firefox =>
firefox-flatpak, but just have different release tags for Flatpaks
within the general "flatpak" namespace. So I started off looking at
doing things this way.
8/7/2023, 4:25:27 PM - Owen Taylor: I started off doing it that way, but
hit an implementation issue in that the "auto release generation"
feature of Koji just looks at all releases in Koji for a N-V and
incremenents the highest one. SO if the highest NVR is
firefox-112.0.2-11.fc38 then you get firefox-112.0.2-12.fc38.
8/7/2023, 4:27:35 PM - Owen Taylor: I *could* implement things manually
- have the plugin look at all release, see which ones match
firefox-112.0.2-*.flatpak, increment the highest one, try to start a
build, if that fails (which should be rair), retry. But it does get
back to the concern that maybe it's confusin
8/7/2023, 4:28:42 PM - Kalev Lember: I am fine with whichever way turns
out to be easier :) You wouldn't have that issue with the other naming
where firefox flatpak is called firefox-flatpak, right?
8/7/2023, 4:28:48 PM - Owen Taylor: That is, firefox-112.0.2-1.flatpak
could contain the rpm firefox-112.0.2-11.f39app (which corresponds to
the unrebuilt firefox-112.0.2-11.fc38)
8/7/2023, 4:29:29 PM - Owen Taylor: Where if we had firefox-flatpak, it
would be more clear that the release numbers were unrelated
8/7/2023, 4:29:48 PM - Kalev Lember: Indeed.
8/7/2023, 4:30:06 PM - Kalev Lember: nirik: what do you think which way
would make more sense?
8/7/2023, 4:31:32 PM - Kalev Lember: I think it's often that you only
discover what makes more sense after trying to go down one path :)
8/7/2023, 4:32:32 PM - Owen Taylor: Yeah, I'm probably inclined to go
with the firefox-flatpak approach at this point - it seems like it will
end up cleaner.
8/7/2023, 4:32:41 PM - Owen Taylor: Another issue that I'm trying to
figure out which way to go with is the relationship between the runtime
and sdk. As Kalev knows, we have complicated scripts in
flaptaks/flatpak-runtime that generate a single module with profiles for
both the runtime and sdk, then flatpaks/flatpak-sdk builds a flatpak
from the flatpak-runtime module.
8/7/2023, 4:33:43 PM - Owen Taylor: But now that we no longer have
modules, how do we handle the fact that the package set for the SDK's
container.yaml comes from flatpaks/flatpak-runtime generation scripts
8/7/2023, 4:34:26 PM - Kalev Lember: Maybe just ignore it for now? We
don't actually use the SDK for anything and I think we can leave
figuring it out for later.
8/7/2023, 4:34:30 PM - Owen Taylor: The simple case, is that we just
have the SDK's container.yaml checked in both places, and manually copy
it over and check it into the SDK
8/7/2023, 4:35:09 PM - Kalev Lember: Sure, I'd be fine with copying it over.
8/7/2023, 4:36:05 PM - Owen Taylor: Other options would be a) just drop
the SDK - as you say we don't actaully use it for anything b) make the
koji-flatpak plugin able to build the SDK from flatpaks/flatpak-runtime
- basically `koji flatpak-build --container-yaml=container-sdk.yaml`
(ignore all details in that) - the container build plugin allows
something like that.
8/7/2023, 4:37:00 PM - Owen Taylor: Kalev Lember: Probably in the
interests of getting something done quickly, I'll make the generation
scripts generate both, and we can figure out if we are copying it over,
or just not building it later :-)
8/7/2023, 4:37:49 PM - Kalev Lember: The SDK can be useful if we ever
end up packaging gnome-builder: In flathub, it's built so that it uses
the SDK as the runtime. But we don't have that and not sure we'll have
it in future either :)
8/7/2023, 4:37:53 PM - Kalev Lember: Sounds like a good plan!
8/7/2023, 4:38:19 PM - Kalev Lember: Do you want help with anything?
8/7/2023, 4:38:36 PM - Owen Taylor: Honestly, the *main* reason we build
the SDK is as an upstream to the RHEL upstream
8/7/2023, 4:38:59 PM - Kalev Lember: Right, so it would be good to
figure it out at some point.
8/7/2023, 4:40:57 PM - Owen Taylor: I think I have to get the basics
committed into dist-git, and a new flatpak-module-tools landed, but at
that point, it would be useful to get some content in place, testing
Flatpak builds with local builds - that would validate things in
parallel with getting koji-flatpak (that is, the Koji Flaptak plugin)
into infrastructure.
8/7/2023, 4:42:42 PM - Kalev Lember: OK, let me know then!
8/7/2023, 4:42:53 PM - Owen Taylor: Will do!
8/7/2023, 4:43:43 PM - * Owen Taylor will have to change his canonical
"first Flatpak to try things on" now that eog is being replaced with
loupe - it's sort of strange to be testing infrastructure with a
replaced application
8/7/2023, 4:44:07 PM - Owen Taylor: loupe will *not* be the first
Flatpak to try things on, though :-)
8/7/2023, 4:46:24 PM - Kalev Lember: Ha, good point :) If you are
looking for a replacement, all the tiny GNOME games could work as they
all have tiny dep sets.
8/7/2023, 4:47:27 PM - Kalev Lember: Anyway, nice work getting it so
far. I'm looking forward to getting rid of mbs, it's getting a bit old
having to fight with it all the time to get builds done.
8/7/2023, 4:47:32 PM - Owen Taylor: Yeah.
8/7/2023, 4:49:00 PM - Kalev Lember: Anything else to discuss? Should we
wrap the meeting up?
8/7/2023, 4:51:01 PM - Owen Taylor: I can't think of anything else. Will
try really hard to get things to the testable state this week. If I
don't manage that, then we're probably looking at F40 for MBS/OSBS
retirement.
8/7/2023, 4:52:06 PM - Kalev Lember: Sound like a plan to me. Thanks
again for working on all this!
8/7/2023, 4:52:27 PM - Kalev Lember: See you all in two weeks -
hopefully we'll have the irc bridge back then.
8/7/2023, 4:52:48 PM - Kalev Lember: #endmeeting (which doesn't actually
do anything right now :) )
