[dependabot]

Bumps github.com/styrainc/regal from 0.28.0 to 0.29.0.

Release notes

Sourced from github.com/styrainc/regal's releases.

v0.29.0

This is a big release, spanning more than a month of development! Regal v0.29.0 brings new linter rules, performance improvements and new features to both the linter and the language server.

New rules

defer-assignment

Category: performance

The new defer-assignment rule helps detect when assignment can be moved to later in the rule body, possibly avoiding it at all if the conditions below don’t evaluate.

allow if {
    # this assignment can be deferred to after the roles check
    resp := http.send({"method": "get", "url": "http:localhost"})
"rego hacker" in input.user.roles
resp.status_code == 200

}

This can improve performance by having less to evaluate, and it makes policies easier to read. Double win!

For more information, see the docs on defer-assignment.

walk-no-path

Category: performance

When using the walk built-in function on large data structures, traversing only the values without building a path to each node can save a considerable amout of time. The new walk-no-path rule will detect when the assigned path is unused and can be replaced by a wildcard variable, which tells OPA to skip the construction of the path. This dramatically improves the performance of the function.

found if {
    # path assigned but never referenced in the rule
    walk(haystack, [path, value])
value == "needle"

}
should be replaced by
found if {
walk(haystack, [_, value])
value == "needle"

}

For more information, see the docs on walk-no-path.
