- the `ruff` section in the `pyproject.toml` is somehow borked? (even
though it def was working a while back..)
- `websockets` is completely broken in latest version since it's using
old-ass `asyncio` APIs of some sort i think??
The quote-msg `'topic'` field was being set and sent as the
`OptionPair.symbol: str` value instead of as the `MktPair.bs_fqme: str`
as is required for matching on the `piker.data.feed` side. So change to
that and simplify the actual `.bs_fqme: str` value to NOT include the
ISO-format time (for now) since it's a big ugly and longer term we need
a `piker`-fqme friendly-on-ze-eyes format/style anyway..
Since it usually means the data-provider backend is keying the msgs
incorrectly (not using the equivalent `MktPair.bs_fqme` which as
would be rendered from the delivered `FeedInit.mkt` instance..) and
reporting the subs list should make it clear how the fqme matching is
off.
Deats,
- use the new `.log.mk_repr()` for a formatter.
- add a commented info emission that can be unmasked to help debug any
such cases as mentioned in the summary ^^.
Such that the `get_hist()` query func raises `DataUnavailable` with an
explicit message regarding the start of the (option) contract's
lifetime.
Other,
- mask some unused imports (for now?)
- drop a duplicate `tractor.get_console_log()` call which was causing
duplicate console emits (it's already setup by brokerd init now).
- comment various unused code bits i found.
- add a info log around live quotes so we can see for the moment when
they actually occur.. XD
There were some imports missing or unused as well as a variety of spots
that had grokability issues due to missing type hints.
Other tweaks as part some more thorough manual testing:
- always raise when not `brokers.toml` section since the API can never
work (no free data without keys).
- inline the `Asset.atype='crypto_currency` field despite it maybe not
being the best value for `OptionPair` instruments..
- tossed in a now-masked pause block for debugging history queries in
`Client.bars()`.
- commented out all the live order ctl (internal) endpoints for now
since they're unused.
Since currently we're only using this IPC subsys for `deribit`, and
generally speaking we're primarly supporting options markets (which are
fairly "slow moving"), flip to a default of NOT resetting the `NoBsWs`
on timeout since doing so normally breaks the jsron-rpc IPC session.
Without a proper `fixture` passed to `open_autorecon_ws()` (which we
should eventually implement!!) relying on a timeout-to-reset more or
less will just cause breakage issues - a proper reconnect sequence must
be implemented before using that feature.
Deats,
- expose and proxy through the `msg_recv_timeout` from
`open_jsonrpc_session()` into the underlying `open_autorecon_ws()`
call.
Namely handling backends which do not provide a default "frame
size-duration" in their init-config by making the backfiller guess the
value based on the first frame received.
Deats,
- adjust `start_backfill()` to take a more explicit
`def_frame_duration: Duration` expected to be unpacked from any
backend hist init-config by the `tsdb_backfill()` caller which now
also computes a value from the first received frame when the config
section isn't provided.
- in `start_backfill()` we now always expect the `def_frame_duration`
input and always decrement the query range by this value whenever
a `NoData` is raised by the provider-backend paired with an explicit
`log.warning()` about the handling.
- also relay any `DataUnavailable.args[0]` message from the provider
in the handler.
- repair "gap reporting" which checks for expected frame duration vs.
that received with much better humanized logging on the missing
segment using `pendulum.Interval/Duration.in_words()` output.
The `open_history_client()` provider endpoint can *optionally*
deliver a `frame_types: dict[int, pendulum.Duration]` subsection in its
`config: dict[str, dict]` (as was implemented with the `ib` backend).
This allows the `tsp` backfilling machinery to use this "recommended
frame duration" to subtract from the `last_start_dt` any time a `NoData`
gap is signalled by the `get_hist()` call allowing gaps to be ignored
safely without missing history by knowing the next earliest dt we can
query from using the `end_dt`. However, currently all crypto$ providers
haven't implemented this feat yet..
As such only try to use the `frame_types` feature if provided when
handling `NoData` conditions inside `tsp.start_backfill()` and otherwise
raise as normal.
