[dependabot]

Bumps github.com/open-policy-agent/opa from 0.40.0 to 0.42.0.

Release notes

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

v0.42.0

This release contains a number of fixes and enhancements.

New built-in function: object.subset

This function checks if a collection is a subset of another collection. It works on objects, sets, and arrays.

If both arguments are objects, then the operation is recursive, e.g. {"c": {"x": {10, 15, 20}} is considered a subset of {"a": "b", "c": {"x": {10, 15, 20, 25}, "y": "z"}.

See the built-in functions docs for all details

This implementation fixes #4358 and was authored by @​charlesdaniels.

New keywords: "contains" and "if"

These new keywords let you increase the expressiveness of your policy code:

Before

package authz
allow { not denied } # `denied` left out for presentation purposes
deny[msg] {
count(violations) > 0
msg := sprintf("there are %d violations", [count(violations)])
}

After

package authz
import future.keywords
allow if not denied # one expression only => no { ... } needed!
deny contains msg if {
count(violations) > 0
msg := sprintf("there are %d violations", [count(violations)])
}

Note that rule bodies containing only one expression can be abbreviated when using if.

To use the new keywords, use import future.keywords.contains and import future.keywords.if; or import all of them at once via import future.keywords. When these future imports are present, the pretty printer (opa fmt) will introduce contains and if where applicable.

if is allowed in all places to separate the rule head from the body, like
