Release Notes

doorkeeper-gem/doorkeeper (doorkeeper)

v5.9.1

• [#​1781] Honor handle_auth_errors :raise in AuthorizationsController#authorize_response

• [#​1795] Fix: detailed error 'insufficient_scope' in protected resources 403s

• [#​1797] Fix doorkeeper:db:cleanup rake task failure on PostgreSQL

• [#​1800] Set @grant_type in ClientCredentialsRequest and RefreshTokenRequest constructors so request.grant_type returns
  the correct value in hooks like before_successful_strategy_response.

• [#​1802] Fix filter_parameters not applied when Doorkeeper.configure is called inside to_prepare.

• [#​1804] Use ActiveSupport.on_load(:active_record) in ORM hooks to prevent loading ActiveRecord models too early

• [#​1806] Fix token revocation bypass for public clients (RFC 7009)

• [#​1815] Expose current_resource_owner as a view helper in Doorkeeper::ApplicationController.

• [#​1818] Fix token introspection returning exp: 0 for non-expiring tokens.

• [#​1784] Remove hardcoded colons from view templates, move punctuation to i18n translation strings.

  [IMPORTANT]: if you have customized Doorkeeper views (authorizations/new, authorizations/show,
  applications/show) or overridden the default en.yml translations, you may need to update them.
  Colons are no longer hardcoded in the views — they are now part of the translation strings.
  Update the doorkeeper-i18n gem to get the
  updated translations for all locales.

• [#​1820] Remove dead wildcard presence check in Scopes#dynamic_scope_match? (internal cleanup, no behavior change).

• [#​1822] Update Rubocop config, auto-corrections.

• [#​1823] Update Rubocop config, part 2.

• [#​1825] Update Rubocop config, part 3.

• [#​1821] Fix noisy Could not find command "no_previous_refresh_token_column?" Thor output during the
  PreviousRefreshTokenGenerator spec by stubbing the underlying DB column check instead of the generator's
  private method (test-only change).
