Unreleased

Changed

• Forked from b-social/liberator-mixin.
• Rename library to liberator.mixin
• Rename :routes to :router in liberator.mixin.hal and liberator.mixin.hypermedia to reflect upstream changes in hype.
• Switch to a multimodule build with the core mixin logic implemented by liberator.mixin.core and the specific mixins moved respectively to:
  • liberator.mixin.authorisation
  • liberator.mixin.context
  • liberator.mixin.hal
  • liberator.mixin.hypermedia
  • liberator.mixin.json
  • liberator.mixin.logging
  • liberator.mixin.validation
• The liberator.mixin.logging mixin now expects a cartus.core/Logger rather than implementing a custom protocol for logging. The liberator.mixin.hal mixin has also been updated to use cartus.core for logging.
• When logging exceptions in liberator.mixin.hal/with-exception-handler, the exception is first converted to a map using clojure.core/Throwable->map in order to retain detail.
• The resource key :self introduced as part of the liberator.mixin.hypermedia mixin has been renamed to :self-link for clarity and the corresponding :self entry added to context has been renamed to :self-link.
• The is- prefix on predicates in liberator.mixin.core has been dropped to follow convention.

Added

• A new SpecBackedValidator has been added to liberator.mixin.validation allowing a spec to be used as a validator, along with a function spec-validator to assist in construction of the validator.
• A new MultiValidator and supporting combine function has been added to liberator.mixin.validation allowing validators to be combined such that all validators must report valid in order for the combined to report valid and such that problems from all validators are combined in the combined validator.
• Two helpers, resource-attribute-as-value and resource-attribute-as-fn, for fetching resource attributes from context, have been added in liberator.mixin.util.
  • resource-attribute-as-value fetches the attribute from the resource and invokes it passing context, returning the result.
  • resource-attribute-as-fn fetches the attribute from the resource and partially applies it using the context, returning a function of the remaining parameters
  • The liberator-mixin.hal namespace now includes a with-malformed-handler mixin for correctly handling malformed responses as a HAL resource.

Fixed

• Fix issue where merging mixins with duplicated decisions e.g. allowed? would duplicate values in sequential collections of the context.

0.0.61 — 2023-01-10

Added

• The liberator-mixin.hal namespace now includes a with-method-not-allowed-handler mixin for correctly handling method not allowed responses as a HAL resource.

Changed

• The with-hal-mixin mixin now includes the with-exception-handler, with-unauthorized-handler, with-forbidden-handler and with-method-not-allowed-handler mixins.

0.0.60 — 2022-07-29

Changed

• When a token is not found on the request but is required, a 401 response is now returned rather than a 400 response.
• The with-jwt-scopes mixin now allows specifying whether a token is required on the request via the :token-required? configuration option.

0.0.59 — 2022-06-30

Added

• with-bearer-token now allows the :token-type configuration option to be a seq of accepted token types, with nil representing there being no token type identifier in the header value. All :token-types are attempted when parsing a token header.

0.0.58 — 2022-06-28

Added

• The liberator-mixin.hal namespace now includes a with-unauthorized-handler mixin for correctly handling unauthorized responses as a HAL resource.
• A with-jwt-scopes mixin has been added in liberator-mixin.authorisation.unverified allowing the scopes claim to be extracted to context but not verified.

0.0.57 — 2021-11-25

Added

• The with-bearer-token mixin now allows the header to look in for a token to be specified via the :token-header-name configuration option, which defaults to "Authorization".

0.0.56 — 2020-09-23

Changed

• The :token-required? configuration option now allows a map of methods to booleans to be used, such that requiring a token can be opted out of for certain methods.

0.0.55 — 2020-09-18

Changed

• The :token-missing configuration option for with-token-authorization has been removed in favour of a new :token-required? configuration option, which when false will allow requests to proceed even if there is no token on the request.
• The malformed? and allowed? decisions for liberator have now been used rather than manually constructing responses within liberator-mixin.authorisation.
• The with-handle-unauthorized-token mixin has been renamed to with-www-authenticate-header.
• Error responses are now rendered via :as-response rather than overriding :handle-unauthorized.
• The ScopeValidator now allows required scopes to be specified by request method.

0.0.54 — 2020-06-25

Changed

• A number of dependencies have been upgraded.
• The with-access-token mixin has been renamed to with-bearer-token.
• The with-jws-access-token mixin has been renamed to with-token-authorization.
• The with-www-authenticate mixin has been renamed to with-handle-unauthorized-token.
• A new :token-missing configuration option has been added for use by with-token-authorization allowing the action to perform in the case of a missing token to be customises, defaulting to responding with an unauthorized response.

0.0.53 — 2020-06-23

Added

• The liberator-mixin.hal namespace now includes a with-forbidden-handler mixin for correctly handling forbidden responses as a HAL resource.

0.0.52 — 2020-06-12

No observable change.

0.0.51 — 2020-06-08

Changed

• The with-jws-access-token mixin now allows a seq of ClaimValidator instances to be provided via the :token-validators configuration option making the claim validator more general purpose and extensible and less opinionated.
• The scope-validator function has been replaced with a ScopeValidator type, implementing ClaimValidator which can be used in the aforementioned :token-validators seq.

0.0.50 — 2020-06-02

Added

• A with-logger mixin has been introduced in the liberator-mixin.logging namespace, allowing a logger to be set on the context for use by other mixins.

0.0.49 — 2020-05-13

Fixed

• The WWW-Authenticate header was incorrectly reporting the underlying error. This has now been resolved.

Changed

• The with-www-authenticate mixin now allows an :error-body to be set on the context, used as the body of the error response.

0.0.48 — 2020-03-04

Added

• A with-jws-access-token-mixin has been added that sets up all parts of JWS access token management.

Changed

• A with-access-token mixin has been pulled out of with-jws-access-token so that extracting and parsing the token can be performed independently without further verification.

0.0.47 — 2020-02-28

Fixed

• Previously verifying multiple scopes failed. This is now resolved.

0.0.46 — 2020-02-28

Added

0.0.45 — 2020-02-28

Changed

• The liberator-mixin.jws-authorisation namespace has been renamed to liberator-mixin.authorisation.
• The with-jws-authorisation mixin has been renamed to with-jws-access-token.
• The with-jws-unauthorised mixin has been renamed to with-www-authenticate.
• Configuration of with-jws-access-token has moved from mixin construction time to runtime by adding :token-type, :token-options, :token-key, :token-claims and :token-parser configuration options to the liberator handler map.
• A scope-validator function has been added to liberator-mixin.authorisation returning a claim validator to be used in the :token-claims configuration option.

0.0.44 — 2020-02-28

Fixed

• Previously, the with-jws-authorisation mixin required the token type in the authorization header (e.g., "Bearer") to match specific casing. Now, the check is case-insensitive.

0.0.43 — 2020-02-24

Changed

• The implementation of errors in with-jws-unauthorised has been tidied up to use a standard error format.

0.0.42 — 2020-02-19

Added

• More tests of the "or" liberator decision changes have been introduced.

Changed

• with-jws-unauthorised-as-json has been renamed to with-jws-unauthorised and no longer returns a JSON error body in the case of an authorisation failure, to comply with the JWT RFC.

0.0.41 — 2020-02-17

Fixed

• Liberator decisions were incorrectly provided with a default value during merge resulting in erroneous decisions in the "or" cases. This has now been resolved.

0.0.40 — 2020-02-17

Fixed

0.0.38 — 2020-02-13

Added

• The with-jws-unauthorised-as-json mixin now includes an OpenID conformant error header on the response in the case of a JWS authorisation failure.

0.0.35 — 2020-02-07

Added

• The liberator-mixin.jws-authorisation namespace has been introduced with a with-jws-authorisation mixin which allows verifying a JWS token on the request, including verifying the contents of the scope claim.

0.0.31 — 2019-09-18

Changed
