Hello,

I'd like the current "tex-team" to be merged into master.

AFAIK, there are no blockers yet.

Regards,

Nicolas Goaziou

Thanks for creating this issue.

The bordeaux build farm hasn't started building the tex-team branch yet,

although I'll try and get that to happen soon.

Unfortunately the build farms still have quite a lot of work to do with

the master branch, if you compare the substitute availability before the

recent core-updates merge [1] to now [2], things are still very lacking

for armhf-linux and i686-linux.

1: https://data.guix.gnu.org/revision/472706ae2f9160833951a4e4bcc4c206e03097b0/package-substitute-availability

2: https://data.guix.gnu.org/repository/1/branch/master/latest-processed-revision/package-substitute-availability

While I realise that waiting to make changes is fustrating, I think it's

important to try and build things before merging so that the effects are

known. This is also good motivation to get more hardware helping to

build things to speed up the process.

Thanks,

Chris

I opened the issue because the "tex-team" branch was fully built on

CI, according to https://ci.guix.gnu.org/eval/461653.

Should I have looked elsewhere before asking for the merge?

I see opening the issue as something to do near the middle of the

process. Similar to opening an issue for some patches, so I think now is

a good time.

However, I'd be sceptical of what you see at [1]. I'm guessing what

you're seeing is correct (at least in the sense of Cuirrass), but there

being no more scheduled builds doesn't mean the branch is good to merge.

1: https://ci.guix.gnu.org/eval/461653

You can see here [2] that while substitute availability is OK for

x86_64-linux and i686-linux, it's poor for all other systems. Also, I

think this might not actually relate to changes on the branch,

substitute availability for aarch64-linux is poor from ci.guix.gnu.org

on the master branch as well.

Looking at https://qa.guix.gnu.org/branch/tex-team, there are 13 new

failures on x86_64 (178 vs. 165), but I’m not sure what they are because

the comparison page shows all the changed derivations (whereas we’d like

to see new failures only).

How can we get that info, Chris?

I did find one “new” failure on the comparison page but I can’t believe

it’s related to changes in the branch:

https://data.qa.guix.gnu.org/gnu/store/a7898v4zq86vzn664g5xh0dq6s1p813k-ams-lv2-1.2.2.drv

So, taking one step back, these numbers come from a comparison of
tex-team and the master branch, and while that sounds sensible, because
it's a comparison of the tips of those branches, I think some of what
you're seeing is breakages that have happened on the master branch but
after the last common commit.

Yeah, as I say above it's possible that this has been broken on master
and not tex-team.

I'll look at getting the comparisons to happen between revisions that
better isolate the changes on the branch, I might just initially ignore
the hard case where the "merge base" in the Git sense isn't know by the
data service.

I'm making some progress, I think I've changed the qa-frontpage in this

way, but unfortunately tex-team branched off master at a revision that

data.qa.guix.gnu.org hasn't got around to processing yet, so currently

there's no comparison.

Maybe the branch could be rebased or master could be merged in? If you

pick the latest commit with a green tick by it from [1], then that

should mean the data service is able to perform the comparison.

Awesome. Perhaps qa-frontpage could be explicit about the commits used

for comparison?

Sounds like a plan. Nicolas?

I rebased the branch on top of c57693846c7c6586c6cd1b4e4002fe399e3a2c42,
which is as green-ticked as a commit can be.

Awesome, the comparison is available now. I've also got the qa-frontpage

to find this issue and start submitting builds (this time for most

systems, not just x86_64-linux).

The QA link at the top (of https://issues.guix.gnu.org/63521) should

now also take you to the relevant page.

There's now some waiting to do for the builds to happen, but also more

work needed on the qa-frontpage to better show any breakages and

failures that occur.

So I still need to do this, however the more significant problem is that

master has diverged significantly (in part at least due to the eudev

change [1] not going to core-updates/another branch).

1: https://lists.gnu.org/archive/html/guix-devel/2023-05/msg00330.html

I've got the qa-frontpage to flag this now, so there should be a warning

at the top of [2] saying there's too many changes between the merge base

and master.

2: https://qa.guix.gnu.org/branch/tex-team

Would you be able to rebase the branch again?

Thanks,

Chris

I rebased the branch on top of 75bdd4b05253c0e6ca5399f60e424f0f00fdb673,
which is green.

Hey,

Substitute availability is looking pretty good for tex-team now [1], it

seems that for most architectures, it only took ~24 hours to recover

from the rebase.

1: https://qa.guix.gnu.org/branch/tex-team

For i686-linux, bordeaux.guix.gnu.org is slow to catch up due to lack of

hardware, and the machine for powerpc64le-linux is temporarily off at

the moment.

I think tex-team is good to merge.
