Since in the receive-side error case the source of the exception is the sender side (normally causing a local `TypeError` at decode time), might as well bundle the error in remote-capture-style using boxing semantics around the causing local type error raised from the `msgspec.msgpack.Decoder.decode()` and with a traceback packed from `msgspec`-specific knowledge of any field-type spec matching failure. Deats on new `MsgTypeError` interface: - includes a `.msg_dict` to get access to any `Decoder.type`-applied load of the original (underlying and offending) IPC msg into a `dict` form using a vanilla decoder which is normally packed into the instance as a `._msg_dict`. - a public getter to the "supposed offending msg" via `.payload_msg` which attempts to take the above `.msg_dict` and load it manually into the corresponding `.msg.types.MsgType` struct. - a constructor `.from_decode()` to make it simple to build out error instances from a failed decode scope where the aforementioned `msgdict: dict` from the vanilla decode can be provided directly. - ALSO, we now pack into `MsgTypeError` directly just like ctxc in `unpack_error()` This also completes the while-standing todo for `RemoteActorError` to contain a ref to the underlying `Error` msg as `._ipc_msg` with public `@property` access that `defstruct()`-creates a pretty struct version via `.ipc_msg`. Internal tweaks for this include: - `._ipc_msg` is the internal literal `Error`-msg instance if provided with `.ipc_msg` the dynamic wrapper as mentioned above. - `.__init__()` now can still take variable `**extra_msgdata` (similar to the `dict`-msgdata as before) to maintain support for subtypes which are constructed manually (not only by `pack_error()`) and insert their own attrs which get placed in a `._extra_msgdata: dict` if no `ipc_msg: Error` is provided as input. - the `.msgdata` is now a merge of any `._extra_msgdata` and a `dict`-casted form of any `._ipc_msg`. - adjust all previous `.msgdata` field lookups to try equivalent field reads on `._ipc_msg: Error`. - drop default single ws indent from `.tb_str` and do a failover lookup to `.msgdata` when `._ipc_msg is None` for the manually constructed subtype-instance case. - add a new class attr `.extra_body_fields: list[str]` to allow subtypes to declare attrs they want shown in the `.__repr__()` output, eg. `ContextCancelled.canceller`, `StreamOverrun.sender` and `MsgTypeError.payload_msg`. - ^-rework defaults pertaining to-^ with rename from `_msgdata_keys` -> `_ipcmsg_keys` with latter now just loading directly from the `Error` fields def and `_body_fields: list[str]` just taking that value and removing the not-so-useful-in-REPL or already shown (i.e. `.tb_str: str`) field names. - add a new mod level `.pack_from_raise()` helper for auto-boxing RAE subtypes constructed manually into `Error`s which is normally how `StreamOverrun` and `MsgTypeError` get created in the runtime. - in support of the above expose a `src_uid: tuple` override to `pack_error()` such that the runtime can provide any remote actor id when packing a locally-created yet remotely-caused RAE subtype. - adjust all typing to expect `Error`s over `dict`-msgs. Adjust some tests to match these changes: - context and inter-peer-cancel tests to make their `.msgdata` related checks against the new `.ipc_msg` as well and `.tb_str` directly. - toss in an extra sleep to `sleep_a_bit_then_cancel_peer()` to keep the 'canceller' ctx child task cancelled by it's parent in the 'root' for the rte-raised-during-ctxc-handling case (apparently now it's returning too fast, cool?). |
