Narrow handshake_status with isinstance instead of int() coercion#158
Merged
Conversation
getattr returns an untyped value off an arbitrary exception, so the prior int(code)/int(status) coercion would raise on a non-numeric .code rather than falling through to None. Guard each membership test with isinstance(..., int) so the value is provably an int before returning it, dropping the redundant int() call. Adds a non-auth (500) response-shape assertion to pin that only 401/403 qualify on either shape.
