Since I was trying out the neat lookin `polars-fuzzy-match` (also added
for now as a core dep here) which requires the new plugin sys, plus it's
about time we synced with upstream!
Adjust some column syntax to the new `.name` sub-field-space and the
`uv` lock-file to match.
Other,
- add back `trio-typing` bc i guess something else needs it (debug
tooling stuff in new `tractor`?)
- flip back to the `tractor` pre-main pin since the new `main`-branch
requires new `trio` stuff we haven't ported yet..
Such that the next time i inevitably must debug the some order-request
error status or precision discrepancy, i have the mkt-symbol branch
ready to go. Also, switch to `'action': 'buy'|'sell' as action,` style
`case` matching instead of the post-`if` predicate style.
Since we're not quite yet using automatic typed msging from
`tractor`/`msgspec` (i.e. still manually decoding order ctl msgs from
built-in types..`dict`s still not `msgspec.Struct`) this adds the
appropriate typecasting ops to ensure the required precision is attained
prior to processing and/or submission to a brokerd backend service.
For the `.clearing._ems`,
- flip all `trigger_price` previously presumed to be `float` to just
the field-identical `price: Decimal` and ensure we cast to `float`
for any `trigger_price` usage, like before passing to `mk_check()`.
For `.ui.order_mode.OrderMode`,
- add a new `.curr_mkt: MktPair` convenience property to get the
chart-active value.
- ensure we always use the `.curr_mkt.quantize() -> Decimal` before
setting any IPC-msg's `.price` field!
- always cast `float(Order.price)` before use in setting line-levels.
- don't bother setting `Order.symbol` to a (now fully removed) `Symbol`
instance since it's not really required-for-use anywhere; leaving it
a `str` (per the type-annot) is fine for now?
By re-typing to a `.price: Decimal` field on both legs of the EMS.
It seems we must do it ourselves since,
- these msg's (fields) are relayed through the clearing engine to each
`brokerd` backend and,
- bc many (if not all) of those backends `.broker`-clients (nor their
encapsulated "brokerage services") **are not** doing any
precision-truncation themselves.
So, for now, instead we opt to expect rounding at the source. This means
we will explicitly require casting to/from `float` at the line-graphics
interface to the order-clearing-engine (as implemented throughout
`.ui.order_mode.OrderMode`); and this is coming shortly.
Instead just check for the field (which i'm not huge on the key-name for
anyway) and if not found get the "last price" from the real-time shm
buffer's latest 'close' sample.
Unrelatedly, use a `subs.copy()` in the `Router.client_broadcast()` loop
such that if a `client_stream` is popped on connection failure, we don't
RTE for the "size changed on iteration".
A new class var `tuple[Exception]` such that the err set can be reffed
externally as needed for catching other similar pub-sub/IPC failures in
other (related) real-time sub-systems.
Also added some now-masked logging for debugging live-feed stream reading
issues that should ONLY be used for debugging since they'll greatly
degrade HFT perf. Used the new `log.mk_repr()` stuff (that one day we
should prolly pull from `modden` as a dep) for pretty console emissions.
Since now `tractor` will raise this native `trio`-exc translated from
a `Stop` msg when the peer gracefully terminates a `tractor.MsgStream`.
Just `info()` log in such cases versus continuing to warn for the
others.
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.
Add a doc-string reflecting recent refinements, drop all the old hook
params, rename `n: trio.Nursery` -> `tn` for "task nursery" fitting with
code base's naming style.
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.
Was orig for debugging an issue with `kucoin` i think but definitely
shouldn't be left in XD
Also add `'perpetual_future'` to the `.start_backfill()` input literal
set since we don't expect the 'btc/usd.perp.binance' for now.
Based on the default provided in their
[docs](https://docs.astral.sh/ruff/configuration/) and migrating
previous config from the prior `poetry`-verion of our `pyproject.toml`
Such that we start encouraging devs to lint code they touch and
hopefully we include a pass as part of our tests/CI eventually B)
Also, mk local `tractor` install `--editable` since without it being
a locally hackable repo it's kinda pointless to install from the local
fs Xp
Seems to be some kinda super weird env bug since we moved to using
`uv`? When it triggers it also seems to cause a pretty fundamental crash
that not only breaks `tractor.devx._debug` stuff but also seems to get
us in a perma-hang state where no SIGINT or other sys sig will be able
to kill the root proc!?!?
TODO, a `gitea` issue to track so we can fix the fundamental problem as
well as transitive fault in `tractor`'s core which seems to be due to
the error taking place during a sub-actor's module import phase which
prevents the runtime from booting fully and then the proc getting stuck
in a real gnarly SIG-state..
This must have broke at some point during the new `MktPair` and thus
`.fqme: str` updates; mas-o-menos the symbol key in the quote-msg-`dict`
was NOT set to the `MktPair.bs_fqme: str` value and thus wasn't being
processed by the downstream sampling and feed subsys.
So fix that as well as a few other refinements,
- set the `topic: mkt.bs_fqme` in quote msgs obvi.
- drop the "wait for first clearing vlm" quote poll loop; going to fix
the sampler to handle a `first_quote` without a `'last'` key.
- add some typing around calls to `get_mkt_info()`.
- rename `stream_messages()` -> `iter_normed_quotes()`.
In line with our move to `uv` and recent `nix` support update a bunch of
the summary content and factor out the order-control section to a new
`.piker.clearing` readme file with embedded todos therein.
