- 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.
- `FeedInit` for init_msgs in `stream_quotes`.
- new cache is `client_pairs` so is replacing the old `client.cache_symbols`.
- `get_mkt_info` added
- `get_ohlc` fixed to comply the new ways of the feed.
key changes:
- Resolved the issue with the expiration dates from deribits, now we int instead of the crazy custom deribits format.
- The client now has a new `_json_rpc_auth_wrapper` that adquires a first access token and then will refresh the access token when this expires.
- `get_assets` fixed, now we use the public endpoint to check the availables assets, in the future probably this will change, but for now is working just fine.
- `get_mkt_pairs` added.
- `exch_info` added.
- `cache_symbols` fixed.
- Also a lot of reformat made in api.
For example in the paper-eng, if you have a backend that doesn't fully
support a symcache (yet) it's handy to be able to ignore processing
other paper-eng txns when all you care about at the moment is the
simulated symbol.
NOTE, that currently this will still result in a key-error when you load
more then one mkt with the paper engine (for which the backend does not
have the symcache implemented) since no fqme ad-hoc query was made for
the 2nd symbol (and i'm not sure we should support that kinda hackery
over just encouraging the sym-cache being added?). Def needs a little
more thought depending on how many backends are never going to be able
to (easily) support caching..
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".
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()`.
Since `tractor`'s new and improved inter-actor cancellation semantics
are much more pedantic, AND bc we use the `ServiceMngr` for spawning
service actors on-demand, the caller of `maybe_spawn_daemon()` should
NEVER conduct a so called "out of band" `Actor`-runtime cancel request
since this is precisely the job of our `ServiceMngr` XD
Add a super in depth note explaining the underlying issue and adding
a todo list of how we should prolly augment `tractor` to make such cases
easier to grok and fix in the future!
Given it's a fairly simple yet useful abstraction, it makes sense to
offer this sub-sys alongside the core `tractor` runtime lib.
Without going into extreme detail on the impl changes (it'll come in
the commit that moves to the other repo) here is the high level summary:
------ - ------
- rename `Services` -> `ServiceMngr` and use an factory `@acm`
to guarantee a single-instance-per-actor using a niche approach for a
singleton object using a default keyword-arg B)
- the mod level `open_service_mngr()` and `get_service_mngr()` are the
new allocation/access API.
- add a `ServiceMngr.start_service()` method which does the work of both
spawning a new subactor (for the daemon) and uses its portal to start
the mngr side supervision task.
- open actor/task nurseries inside the `@acm` allocator.
Adjust other dependent subsystems to match:
------ - ------
- use `open_service_mngr()` when first allocated in `open_pikerd()`.
- use `get_service_mngr()` instead of importing the class ref inside
`.service.maybe_spawn_daemon()`, `.brokers._daemon.spawn_brokerd()`
and `.data._sampling.spawn_samplerd()` using a `partial` to pack in
the endpoint ctx kwargs (unpacked inside `.start_service()` XD).
Was orig for debugging an issue with `kucoin` i think but definitely
shouldn't be left in XD
Also add `'perpetual_future'` to `start_backfill()` input literal set.
Since the last `poetry` update the command `poetry shell` have been
moved to a plugin, this affects the entire instalation, so now we
need to add more deps to the `buildInputs` and added to the
`LD_LIBRARY_PATH`
To run a command now you need to do something like this:
`poetry run piker ...`
About time we tidy'd a buncha status logging in this backend..
particularly for boot-up where there's lots of client-try-connect poll
looping with account detection from the user config.
`.api.Client` pprint and logging fmt improvements:
- add `Client.__repr__()` which shows the minimally useful set of info
from the underlying `.ib: IB` as well as a new `.acnts: list[str]`
of the account aliases defined in the user's `brokers.toml`.
- mk `.bars()` define a comprehensive `query_info: str` with all the
request deats but only display if there's a problem with the response
data.
- mk `.get_config()` report both the config file path and the acnt
aliases (NOT the actual account #s).
- move all `.load_aio_clients()` client poll loop requests do
`log.runtime()` statuses, only falling through to a `.warning()` when
the loop fails to connect the client to the spec-ed API-gw addr, and
|_ don't allow loading accounts for which the user has not defined an
alias in `brokers.toml::[ib]`; raise a value-error in such cases
with a message indicating how to mod the config.
|_ only `log.info()` about acnts if some were loaded..
Other mod logging de-noising:
- better status fmting in `.symbols.open_symbol_search()` with
`repr(Client)`.
- for `.feed.stream_quotes()` first quote reporting use `.runtime()`.
- timestamps came as `'date'`-keyed from 2022 and before but now are
`'datetime'`..
- some symbols seem to have no commission field, so handle that..
- when no `'price'` field found return `None` from `norm_trade()`.
- add a warn log on mid-fill commission updates.
Like other backends use the `AsyncClient` for all venue specific
client-sessions but change to allocating them inside `get_client()`
using an `AsyncExitStack` and inserting directly in the
`Client.venue_sesh: dict` table during init.
Supporting impl tweaks:
- remove most of the API client session building logic and instead make
`Client.__init__()` take in a `venue_sessions: dict` (set it to
`.venue_sesh`) and `conf: dict`, instead opting to do the http client
configuration inside `get_client()` since all that code only needs to
be run once.
|_load config inside `get_client()` once.
|_move session token creation into a new util func `init_api_keys()` and
also call it from `get_client()` factory; toss in an ex. toml section
config to the doc string.
- define `_venue_urls: dict[str, str]` (content taken from old static
`.venue_sesh` dict) at module level and feed them as `base_url: str`
inputs to the client create loop.
- adjust all call sigs in httpx-sesh-using methods, namely just
`._api()`.
- do a `.exch_info()` call in `get_client()` to cache the symbology
set.
Unrelated changes for various other outstanding buggers:
- to get futures feeds correctly loading when selected
from search (like 'XMRUSDT.USDTM.PERP'), expect a `MktPair` input to
`Client.bars()` such that the exact venue-key can be looked up (via
a new `.pair2venuekey()` meth) and then passed to `._api()`.
- adjust `.broker.open_trade_dialog()` to failover to paper engine when
there's no `api_key` key set for the `subconf` venue-key.
Like we do with other history backends to indicate lack of a data set.
This avoids any raise that will will bring down the backloader task with
some downstream error.
Raise a `ValueError` on no time index for now.
Code base is already ported for `Qt6` so this removes the pyqt5 dep,
adds latest pyqt6 as well as buncha other updates:
- add `xonsh` and ptk as dev deps for those of us using wacky shells ;P
- bump compiled deps as needed for python 3.12 (`numpy`, `numba`)
- add `httpx` and drop `asks` since the latter is zombied and not compat
with other libs on 3.12.
- add `ruff` linting ignore rules for the new `.ui.qt` shim mod layer.
- few other deps updates to latest versions.
- add in the `keywords` and `classifiers` sections from the old
`setup.py`.
This also officially moves the code base to using `PyQt6` including all
necessary reference changes and enum namespace path moves.
Also includes a small `.ui.order_mode` fix to cancel any
`Order.price <= 0` and a name error fix with logging using `msg`,
which is already used for the input order msg..
For the future, like if we ever get a `PyQt7` (or wtv else..), add
a module which allows changing Qt binding lib imports from one spot for
all other `.ui` submodules. In some sense this is like a shoddier, less
dynamic version of how `pyqtgraph.Qt.__init__.py` supports multiple
libs; it might actually make sense eventually to instead import from
their shim layer instead?
Included is a draft attempt at exposing a bunch of enums which under
custom names:
- while the specific grouping of values seem to always stay consistent,
the root enum's seem to almost always get moved around in the `PyQtX`
module namespace.
- changing groupings and/or each top level enum's ns location can more
simply be changed/re-orged from one spot.
- allows `.ui` consumer code to use a name more relevant to `piker`'s
usage of wtv UI component is being configured.
Such that our internal structs can be pretty printed with indented and
type-hinted fields, AND for nested `Struct`-fields call `.pformat()` but
avoiding any recursion errors using `pprint.saferepr()`. Add
a `._sin_props()` iterator over the non-property fields; use it for
`dict` casting when called with `.to_dict(include_non_members=False)`.
Actually, we should also probably figure out how to only pprint like
when required by the user in a REPL or log msg by context-selectively
`pprint.PrettyPrinter` right? Also, if we can generalize decently enough
it'd be cool to maybe patch this in as a util to upstream `msgspec`?
Ran into this trading a peenee where a dark got (mistakenly) submitted
at a price of 0 and then that consecutively broke upstream allocator/pp
code due to a divide-by-zero.. So instead always check for a zero-price
(since that should never ever be valid in any market) and instead cancel
any such order in the EMS and return `None` so that upstream callers can
ignore it without crash handling.
