Bumps github.com/open-policy-agent/opa from 1.15.0 to 1.17.0.

Release notes

Sourced from github.com/open-policy-agent/opa's releases.

v1.17.0

This release contains a mix of new features, performance improvements, and bugfixes. Notably:

• A new future.keywords.not import that adds improved semantics to the not keyword.
• Rule Labels in Decision Logs
• Published json schema for IR and bundle manifest
• Dropped automaxprocs and x/net dependencies

Improved Negation Semantics (#8387)

This OPA release introduces a new future.keywords.not import that fixes a long-standing semantic issue with negation in Rego.

Without the import, the compiler expands a negated composite expression like not f(g(input.x)) into a series of sub-expressions evaluated before the not:

__local0__ = input.x
g(__local0__, __local1__)
not f(__local1__)

If any sub-expression fails — for example, input.x is undefined or g produces an undefined result — the entire rule fails rather than the not succeeding. This is unintuitive: the user's intent is "the condition does not hold," but an undefined intermediate value causes a silent failure instead of the expected not result.

With import future.keywords.not, composite-expression negation wraps the full compiler expansion in an implicit body:

not { __local0__ = input.x; g(__local0__, __local1__); f(__local1__) }

Now, if any sub-expression is undefined or fails, the body is unsatisfiable and the not expression succeeds; matching the intuition that "the condition does not hold."

NOTE:

Users are recommended to import future.keywords.not whenever the not keyword is used in a policy.

Rule Labels in Decision Logs (#2089)

Rule annotations now support a labels field. Labels from all successfully evaluated rules are collected and included in each decision log entry as a top-level rule_labels array. Each element is the merged label map for one successfully evaluated rule, with
