This is for the time being an empty bucket. The goal is to reserve a
space in the queue, and then to try out the suggestion developed in
my message to guix-devel: "Branches and other updates"
The idea is to collect a few updates that cause many rebuilds, but are
not covered by a team. The corresponding commits will be collected
in a milestone on codeberg, and decided upon once this branch moves
closer to the front of the queue.

The branch has been started on August 23.

Over the last day it has ground to a halt; I see error message like this
in the build coordinator:
2025-08-25 11:43:01 @ download-progress /gnu/store/55ay81kd2gdh5xjcwlzl9g1nmwih91al-tvm-0.20.dev0-1.d3a2ed6.drv https://data.guix.gnu.org/nar/55ay81kd2gdh5xjcwlzl9g1nmwih91al-tvm-0.20.dev0-1.d3a2ed6.drv 776 776
…
2025-08-25 11:43:01       message: "derivation `/gnu/store/55ay81kd2gdh5xjcwlzl9g1nmwih91al-tvm-0.20.dev0-1.d3a2ed6.drv' has incorrect output `/gnu/store/x8mbs7k5ynwjd16aly14h49bphgv43qf-tvm-0.20.dev0-1.d3a2ed6', should be `/gnu/store/2z33z4qzxxyllm5a9i7acsha53a3p9n0-tvm-0.20.dev0-1.d3a2ed6'"

for a number of packages.

And another type of error:
2025-08-25 11:49:48       message: "path `/gnu/store/x5p6qihyhiiggp9vcy0jbklq7cml0wva-cl-spatial-trees-0-1.81fdad0.drv' does not exist and cannot be created"

I do not see how the first situation can occur.

These are frightening, but I realise that they cannot be related to the
branch: This comes from data and not data.qa. So it must be related to
building the master branch, which seems to work: I see recently being
updated packages that are built.

So the problem must be somewhere else...

I have rebased on 06f79dc2bd44ca292dade633d344c3f70749b9e7 to capture
the latest update to qtbase on master.

Yeah, there's something wrong with the data service processing revisions
in that sometimes some of the derivation information (inputs/sources)
can be missing from the database, which manifests as failures to
substitute the derivations.

This shouldn't have been possible in the first place, so it's really
hard to tell if I've fixed whatever caused these data issues. I've been
looking in to trying to find and fix the broken derivations on
data.guix.gnu.org today but I've got stuck as Guix is refusing to
substitute a store item, and I can't tell why, which hints at some
potential new problem with the data:

  https://codeberg.org/guix/maintenance/issues/25

Unfortunately as I say, there's no information as to what is going
wrong, so I've given up for now.

For the last two days, QA has stopped building packages.
As aarch64 has been successfully finished, I am confident that the
patches on the world-rebuild branch are good to go. On x86_64, there
are still 3500 packages to be built on QA, but they look good on the
CI dashboard. i686 has noticeably more packages being blocked by build
failures on QA, but the biggest blocker there, ghc, appears to be
available on CI.

So I have rebased the branch and pushed it to master.

Over the next two weeks, I will mostly be away from keyboard, and after
that probably spend less time than over the summer to work on branches.
So please organise yourselves to follow the branches on
   https://qa.guix.gnu.org/
and merge one after the other when they are ready; depending on the
state of QA, this may require to also have a look at CI.

Andreas
