parameters_map_postdecl

Overview ¶

Package parameters_map_postdecl witnesses a bug in the parameters builder's buildFromFieldMap path.

LocalItem below is deliberately NOT annotated with swagger:model. Its only reachable site is the map-valued body parameter on MapParams. The parameters builder walks into buildFromFieldMap, which spins up a fresh schema sub-builder for the map's value type. The sub-builder discovers LocalItem and registers it on its own PostDeclarations slice. The parameters builder is supposed to propagate that registration to its own AppendPostDecl chain — but buildFromFieldMap omits that loop (every other buildFromFieldXxx method has it).

Without the propagation, spec.Builder.buildDiscovered never sees LocalItem; the resulting definitions section is missing the schema, and the spec is internally inconsistent (the map's value shape vanishes silently).

The pre-fix golden captures this buggy state. The fix commit regenerates the golden to show LocalItem appearing in the definitions section.
