Prerelease: no

Release notes:

Added

• The [promql/impossible](checks/promql/impossible.md) check will now warn about aggregations and

and binary operations that try to operate on labels that are already removed in the query. Example:

- record: foo
expr: sum(foo) / on(cluster) sum(bar)

The above tries to join two series on the cluster label, but sum(...) already removed labels from the results on both side, so there will be no such label on join on.

• The [promql/impossible](checks/promql/impossible.md) check will now warn about label joins

using group_left(...) and group_right(...) that are not possible or not used in any way.

Fixed

• For queries using binary expressions between two vectors Prometheus will remove the metric name

from resulting series, pint will now also apply the same logic when checking queries.
