Description
Introduce a new Go type
EntitlementSet(maybe needs a more descriptive name, suggestions very welcome), which is a conjunction of entitlement types, and disjunctions of entitlements. For example, it can represent{A, B, (C | D)}. This allows representing more complex entitlement sets than access/auth entitlement sets can (only conjunction or disjunction of entitlements, e.g.{A, B}OR{A | B})Switch
EntitlementSupportingType.SupportedEntitlementsto returnEntitlementSet.Implementations of the function combine sub-sets – for example, composite type's implementation merges the entitlement sets of all members, and intersection type's implementation merges the entitlement sets of all interface types' supported entitlements. Switching the return type to a set type which is able to represent more complex sets results in less "information loss" in recursive calls.
As a result, when translating the resulting entitlement set to an access, it is possible to get a disjunction now, which was not previously possible.
Given
EntitlementSupportingType.SupportedEntitlementsis used in the entitlements migration and the contract update checker to infer the entitlements/auth, these changes should hopefully result in authorizations that are less permissive than before.masterbranchFiles changedin the Github PR explorer
