The typed oslo.config stubs introduced new type mismatches that
needed attention across five files.
An empty set() without annotation left mypy unable to infer the
element type, so _DEPRECATED_EXCEPTIONS now carries an explicit
set[type] annotation.
The list_opts() concatenation mixed list[BoolOpt] with list[Opt]
via the + operator, which mypy rejects because list is invariant.
Switching to unpacking ([*a, *b, ...]) builds a single list whose
element type is the union of all sources, sidestepping the issue
without casts or redundant annotations on each individual list.
_store_global_conf was annotated as returning ConfigOpts but never
returns anything — the return type is now None to match reality.
The tuple-based membership checks in _mutate_hook ((None, 'debug')
in fresh) are a legitimate oslo.config API pattern for querying
mutated options by (group, name), but the typed stubs only declare
__contains__(str). These are silenced with type: ignore until the
stubs are updated upstream.
The TestConfigOpts.__call__ override intentionally narrows the
parent signature to hardcode test defaults — this is a deliberate
simplification for test ergonomics, not a Liskov violation worth
fixing, so it gets a type: ignore[override].
