Turns out the generics based payload speccing API, as in https://jcristharif.com/msgspec/supported-types.html#generic-types, DOES WORK properly as long as we don't rely on inheritance from `Msg` a parent `Generic`.. So let's get real pedantic in the `mk_msg_spec()` internals as well as verification in the test suite! Fixes in `.msg.types`: - implement (as part of tinker testing) multiple spec union building methods via a `spec_build_method: str` to `mk_msg_spec()` and leave a buncha notes around what did and didn't work: - 'indexed_generics' is the only method THAT WORKS and the one that you'd expect being closest to the `msgspec` docs (link above). - 'defstruct' using dynamically defined msgs => doesn't work! - 'types_new_class' using dynamically defined msgs but with `types.new_clas()` => ALSO doesn't work.. - explicitly separate the `.pld` type-constrainable by user code msg set into `types._payload_spec_msgs` putting the others in a `types._runtime_spec_msgs` and the full set defined as `.__spec__` (moving it out of the pkg-mod and back to `.types` as well). - for the `_payload_spec_msgs` msgs manually make them inherit `Generic[PayloadT]` and (redunantly) define a `.pld: PayloadT` field. - make `IpcCtxSpec.functype` an in line `Literal`. - toss in some TODO notes about choosing a better `Msg.cid` type. Fixes/tweaks around `.msg._codec`: - rename `MsgCodec.ipc/pld_msg_spec` -> `.msg/pld_spec` - make `._enc/._dec` non optional fields - wow, ^facepalm^ , make sure `._ipc.MsgpackTCPStream.__init__()` uses `mk_codec()` since `MsgCodec` can't be (easily) constructed directly. Get more detailed in testing: - inside the `chk_pld_type()` helper ensure `roundtrip` is always set to some value, `None` by default but a bool depending on legit outcome. - drop input `generic`; no longer used. - drop the masked `typedef` loop from `Msg.__subclasses__()`. - for add an `expect_roundtrip: bool` and use to jump into debugger when any expectation doesn't match the outcome. - use new `MsgCodec` field names (as per first section above). - ensure the encoded msg matches the decoded one from both the ad-hoc decoder and codec loaded values. - ensure the pld checking is only applied to msgs in the `types._payload_spec_msgs` set by `typef.__name__` filtering since `mk_msg_spec()` now returns the full `.types.Msg` set. |
