Description

The DiracX Unit Tests job currently fails for all PRs with:

× task 'pytest-gubbins-all-one-by-one' depends on task 'pytest-gubbins-core' in environment 'gubbins-core', which is not defined

The "Apply workarounds" step (introduced in 537fd13) uses the following sed to break the gubbins environments out of their shared solve group:

sed -i.bak '/solve-group = "gubbins"/d' pixi.toml

However, in diracx's pixi.toml every gubbins environment is defined as a single-line inline table ending with , solve-group = "gubbins"}:

gubbins-core = {features = ["task-gubbins-core", "diracx-core", "gubbins-core"], solve-group = "gubbins"}

The sed therefore deletes the entire environment definition instead of only the solve-group clause. All gubbins environments (gubbins-core, gubbins-api, ...) disappear from the manifest, while the root meta-task pytest-gubbins-all-one-by-one still declares depends-on entries pointing at tasks in those now-undefined environments. Recent pixi versions validate cross-environment task dependencies strictly and fail the pixi add call in the workaround step.

This PR strips only the , solve-group = "gubbins" clause, keeping every environment defined while still decoupling it from the shared solve group:

sed -i.bak 's@, solve-group = "gubbins"@@g' pixi.toml

Verified locally against diracx main (pixi.toml from the current master commit): with the broken sed pixi warns that all gubbins features are unused (environments deleted); with this fix the manifest parses cleanly and all pytest-gubbins-* environments and tasks are present.

The failure is unrelated to the changes of any individual PR — it is pre-existing on integration since 537fd13.

The workaround hasn't changed since May, but from what I can see locally, the last passing runs used 0.82.0 and the failing ones use 0.82.1, so I assume pixi is becoming stricter.
The workaround is deleting the gubbins environment but [tasks.pytest-gubbins-all-one-by-one] in diracx's pixi.toml still refers to them, that's what is raising the error.

Gubbins environment was intentionally removed, because the CI is only running pytest-diracx-all-one-by-one (gubbins is not needed in this context, and it's tested in the diracx CI).
So I assume the right fix would be:

# Drop the gubbins environments entirely: this job doesn't use them, and the
# `pixi add --feature diracx-core` calls below would otherwise re-solve them too
sed -i.bak '/solve-group = "gubbins"/d' pixi.toml
rm pixi.toml.bak
# The gubbins environments are removed above; drop the task that references them
awk '/^\[tasks\.pytest-gubbins-all-one-by-one\]/{skip=1;next} skip&&/^\[/{skip=0} !skip' pixi.toml > pixi.toml.new
mv pixi.toml.new pixi.toml
