Since adding more complex inter-peer (actor) testing scenarios, we
definitely have an immediate need for `trio`'s style of "inceptions" but
for nesting `RemoteActorError`s as they're relayed through multiple
actor-IPC hops. So for example, a remote error relayed "through" some
proxy actor to another ends up packing a `RemoteActorError` into another
one such that there are 2 layers of RAEs with the first
containing/boxing an original src actor error (type).
In support of this extension to `RemoteActorError` we add:
- `get_err_type()` error type resolver helper (factored fromthe
body of `unpack_error()`) to be used whenever rendering
`.src_type`/`.boxed_type`.
- `.src_type_str: str` which is pulled from `.msgdata` and holds the
above (eventually when unpacked) type as `str`.
- `._src_type: BaseException|None` for the original
"source" actor's error as unpacked in any remote (actor's) env and
exposed as a readonly property `.src_type`.
- `.boxed_type_str: str` the same as above but for the "last" boxed
error's type; when the RAE is unpacked at its first hop this will
be **the same as** `.src_type_str`.
- `._boxed_type: BaseException` which now similarly should be "rendered"
from the below type-`str` field instead of passed in as a error-type
via `boxed_type` (though we still do for the ctxc case atm, see
notes).
|_ new sanity checks in `.__init__()` mostly as a reminder to handle
that ^ ctxc case ^ more elegantly at some point..
|_ obvi we discard the previous `suberror_type` input arg.
- fully remove the `.type`/`.type_str` properties instead expecting
usage of `.boxed_/.src_` equivalents.
- start deprecation of `.src_actor_uid` and make it delegate to new
`.src_uid`
- add `.relay_uid` propery for the last relay/hop's actor uid.
- add `.relay_path: list[str]` which holds the per-hop updated sequence
of relay actor uid's which consecutively did boxing of an RAE.
- only include `.src_uid` and `.relay_path` in reprol() output.
- factor field-to-str rendering into a new `_mk_fields_str()`
and use it in `.__repr__()`/`.reprol()`.
- add an `.unwrap()` to (attempt to) render the src error.
- rework `pack_error()` to handle inceptions including,
- packing the correct field-values for the new `boxed_type_str`, `relay_uid`,
`src_uid`, `src_type_str`.
- always updating the `relay_path` sequence with the uid of the
current actor.
- adjust `unpack_error()` to match all these changes,
- pulling `boxed_type_str` and passing any resolved `boxed_type` to
`RemoteActorError.__init__()`.
- use the new `Context.maybe_raise()` convenience method.
Adjust `._rpc` packing to `ContextCancelled(boxed_type=trio.Cancelled)`
and tweak some more log msg formats.
