Add structured_params-openapi gem with OpenAPI drift check - #22
Merged
Merged
Conversation
The drift check feature (added in 3b1efbd) crashed any Rails boot (rails runner/console) when Thor::Actions partially loaded rake internals without mixing Rake::DSL into main. Loading the rake task now happens through a Rails::Railtie#rake_tasks hook instead of an unconditional require-time load. Also, dogfooding the feature against a real app's OpenAPI document and StructuredParams classes surfaced several rough edges, fixed here: - DriftCheck::Result#to_message is now prefixed with the checked class's name, so Registry.check_all!'s combined DriftError message reads as one block per class instead of an unattributed flat list of paths. - A single-entry `allOf` (the common TypeSpec/OpenAPI idiom for attaching a description/default next to a $ref, since $ref forbids sibling keys) is unwrapped and compared instead of being skipped as unsupported composition. - A schema pointer that can't be resolved (e.g. a resolver-guessed name with no matching component) is now recorded as a skip instead of raising KeyError and aborting every other class's check. - Registry.register accepts a class-name String, resolved lazily in check_all, so registering from a plain Rails initializer no longer needs a to_prepare workaround for Zeitwerk autoloading timing. - Configuration#ignore_drift(path:, kind:) suppresses one specific finding (by path and, optionally, kind) across every check, for cases where the Ruby side is correct but the check's structural heuristics can't see it (e.g. presence enforced only through conditional validators). Ignored findings move to Result#ignored rather than disappearing, so they stay auditable.

Review comments at @.mise.toml:
- Line 2: Update the Ruby version pin in the mise configuration from 4.0.5 to
4.0.7 so it matches the Ruby patch tested by CI.
Review comments at @docs/openapi-drift-check.md:
- Line 22: Update the documented default mapping suffix list to include Param
alongside Params, Parameter, Parameters, and Form, so it covers classes such as
CreateUserParam.
- Around line 125-126: Update the scope description to say the checker skips
multi-entry allOf schemas, not all allOf schemas; preserve the existing mentions
of oneOf, anyOf, and multiple-type schemas.
Review comments at @lib/structured_params/open_api/drift_check.rb:
- Around line 298-300: Update resolve_references to track visited reference
strings and skip resolving a reference when it has already been visited,
preventing cycles in pure refs and refs inside items from recursing
indefinitely. Pass or maintain this visited set across recursive calls rather
than relying on object identity.
- Line 24: Add type annotations for the Issue Struct attributes in
lib/structured_params/open_api/drift_check.rb:24, and replace the disable/enable
directive pairs at lines 10, 65, 87, 162, and 217 with disable-next directives.
In lib/structured_params/open_api/configuration.rb:59, update the annotation to
use self.@configuration with the nullable Configuration type; in
lib/structured_params/open_api/registry.rb:13, use self.@entries with the
nullable Array[Array[untyped]] type. In spec/open_api/railtie_loading_spec.rb:6,
use a disable-next directive for RSpec/DescribeClass and remove its matching
enable directive.
Review comments at @README_ja.md:
- Line 112: Update the README example wording to describe selecting the
namespace of request parameter classes to check via `parameter_class_filter`,
rather than registering each class; keep it clear that class discovery is
automatic and distinct from `Registry.register`.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick winCreate the stubbed class before auto-discovery runs.
parameter_classis a lazylet. No code reads it beforecheck_all(auto_discover: true). The first read happens inside the filter lambda. At that point,ObjectSpace.each_object(Class)is already iterating, andstub_constcreates a new class during the iteration. That new class is not in the enumeration, so the filter never matches. CI on Ruby 3.4 reports 0 results instead of 1. Uselet!so that the class exists before discovery starts.💚 Proposed fix

…openapi gem Move the drift check out of the core gem into structured_params-openapi, kept in this repository as a subdirectory with its own gemspec, sig, specs and docs. The core no longer loads any OpenAPI code or Rake task. - gem structured_params-openapi (require 'structured_params/openapi'), which depends on structured_params >= 0.9.5 - module is StructuredParams::OpenAPI; the Railtie is StructuredParams::OpenAPI::Railtie - Gemfile, Rakefile, Steepfile, lefthook, AGENTS.md and RuboCop config cover both gems; the core README points to the new gem Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
