Additional context

The cause of this build failure is that python312Packages.rich was updated from 13.9.4 to 14.0.0, which no longer satisfies woob's version constraint. This was performed in commit 6c22a1c, and merged in PR #395156.

The primary impact of this issue is that KMyMoney no longer builds on the latest unstable, as it depends on woob.

I'm not using woob anymore. Anyone willing to take over?

pinging the maintainers of KMyMoney as the only application in Nixpkgs that depends on woob: @aidalgol @das-g

As far as I can see on https://gitlab.com/woob/woob, there isn't yet any woob version (neither a released one, nor one in development) declaring a 14.x version of rich as acceptable, nor do I see any plans in their issue tracker up bump the rich dependency version upper bound.

This seems understandable to me, as according to https://rich.readthedocs.io/en/latest/ and https://rich.readthedocs.io/en/stable/, while the latest version of rich is 14.0.0, the latest stable version of rich is still 13.6.0.

Do we have any software in NixPkgs depending on a rich version greater than 13.6.0? If not, would it be an option to roll rich back to that stable version, @risicle?

[Maxwell-lt]

Rolling back to the final 13.x rich version (13.9.4) would also satisfy the version constraint in woob, and I also don't think that 13.6.0 is actually meant to be marked as stable.

Looking deeper into the ReadTheDocs setup, it seems like 13.6.0 being marked as "stable" isn't actually intended. The ReadTheDocs build for stable has just been failing for a while. See the builds page, and notably the latest build attempt for the stable docs, which is checking out Textualize/rich@72e3bb3. It looks like 14.0.0 is actually considered "stable" by rich.

Rolling back rich seems like the best option to me as well to get these builds fixed quickly.

As a final note, it might not be too difficult to get the woob devs to update to 14, since the scope of the breaking changes in 14.0.0 are minor. Per the release notes, the breaking part is that an empty NO_COLOR or FORCE_COLOR environment variable is now treated as being disabled, which I would guess either will have no impact or a minor impact on woob.

Let's see. I've now filed a task to upgrade rich at the woob upstream repo.

[Maxwell-lt]

In case we do want to revert rich to 13.9.4, I opened a PR which reverts the update.

[Maxwell-lt]

In the linked PR, @NickCao pointed out that we can just add rich to the pythonRelaxDeps list. I tried this out locally and it does fix the build. I'll open a PR against woob with this fix applied.
