Apparently they're being massive cucks and changing their futes pair
schema again now adding a `NEXT_QUARTER` contract type which we weren't
handling at all. The good news is falling back to an old symcache file
would have prevented this from crashing.
Add a new `FutesPair.expiry: str` field so that `.bs_fqme` can simply
call it during the summary FQME-ification output rendering..
A helper for scanning a "pairs table" that most backends should expose
as part of their (internal) symbology set using `rapidfuzz` over
a `dict[str, Struct]` input table.
Also expose the `data.types.Struct` at the subpkg top level.
Previously we were assuming that the `Client._contracts: dict[str,
Contract]` would suffice this directly, which obviously isn't true XD
Also,
- add the `NSE` venue to skip list.
- use new `rapidfuzz.process.extract()` lib API.
- only get con deats for non null exchange names..
Since `poetry` doesn't seem to actually mark optional group deps as such
in the lock file (!?) manually generate a `poetry.lock` with the
optional groups commented out in the `pyproject.toml`; this is all in
an attempt at trying to make `poetry2nix` build without any UI components
which seem to be the source of much frustration without hacking on p2n
and/or nixpkgs repos..
Further drop all the old build system files including the
setup.py and requirements.txt files.
Of course I missed this first try but, we need to use the ws market pair
symbology set (since apparently kraken loves redundancy at least 3 times
XD) when processing transactions that arrive from live clears since it's
an entirely different `LTC/EUR` style key then the `XLTCEUR` style
delivered from the ReST eps..
As part of this:
- add `Client._altnames`, `._wsnames` as `dict[str, Pair]` tables,
leaving the `._AssetPairs` table as is keyed by the "xname"s.
- Change `Pair.respname: str` -> `.xname` since these keys all just seem
to have a weird 'X' prefix.
- do the appropriately keyed pair table lookup via a new `api_name_set:
str` to `norm_trade_records()` and set is correctly in the ws live txn
handler task.
Since we eventually want to allow users to minimally deploy `pikerd`
service-tree (aka distributed cross host) installs, we need to offer
a "headless" deps group. Really this is just the core dep set minus Qt
and some aux search related libs (for now).
The new `.dev` group is for adding hacking and testing tools including
`xonsh` since that will eventually be our REPL of choice more then
likely B)
Oh, and fix the namespace path (was a typo) for the `ledger` CLI and
of course bump the lock file.
Makes it easier to pass the overrides to multiple p2n functions (like
hopefully `.mkPoetryEnv`). Also, add some commented attempts at using
`mkPoetryEnv` and todo list for "why", remove the `poetry` CLI main
point from the pyproject.toml, bump the poetry lock file.
NB: for now this is linking to a presumed local clone of the
`poetry2nix` repo since part of fixing what was adjusted here needs to
be patched upstream, which means hackin on the p2n repo in tandem B)
Since there's some dependency build issues we need
to tweak the following to get baseline `nix develop` working:
- drop `python-levenshtein` (required by `fuzzywuzzy[speedup]`) for now
since the overlay and/or wheel install needs to be properly figured
out.
- build `pyqt5` from src for the moment (since `preferWheel` doesn't
seem to be workin?) despite it taking forever XD
- add in the `flake.lock` file.
As per the hot tip from the edgecases.md,
https://github.com/nix-community/poetry2nix/blob/master/docs/edgecases.md#modulenotfounderror-no-module-named-packagename
Factor all the (mostly `setuptools`) overrides into
a `pypkgs-build-requirements` set and `.extend()` in any `preferWheel`
additions (`polars`, `pyqt`, etc.) before passing to to
`mkPoetryApplication(overrides=<it>)`.
Add a buncha todos for improving the poetry2nix pkging including:
- adding the override requirements to the json file for all our deps
in the `pypkgs-build-requirement` set.
- maybe propose docs for the edgecases.md to show how to do the auto-gen
set (via func) AND extend with further overrides like `preferWheel`?
- task to support `polars` build from src (by copying `cryptography`
stuff) instead of only from a wheel?
- get pyqt5 building from wheel since it seems to be taking forever from
src..
- get pyqt6 working in general - going to require taking stuff from
nixpkgs and applying it in the overrides of p2n.
This is a tricky edge case we weren't handling prior; an example is
submitting a limit order with a price tick precision which mismatches
that supported (probably bc IB reported the wrong one..) and IB responds
immediately with an error event (via a special code..) but doesn't
include any `Trade` object(s) nor details beyond the `reqid`. So, we
have to do a little reverse EMS order lookup on our own and ideally
indicate to the requester which order failed and *why*.
To enable this we,
- create a `flows: OrderDialogs` instance and pass it to most order/event relay
tasks, particularly ensuring we update update ASAP in `handle_order_requests()`
such that any successful submit has an `Ack` recorded in the flow.
- on such errors lookup the `.symbol` / `Order` from the `flow` and
respond back to the EMS with as many details as possible about the
prior msg history.
- always explicitly relay `error` events which don't fall into the
sensible filtered set and wrap in
a `BrokerdError.broker_details['flow']: dict` snapshot for the EMS.
- in `symbols.get_mkt_info()` support adhoc lookup for `MktPair` inputs
and when defined we re-construct with those inputs; in this case we do
this for a first mkt: `'vtgn.nasdaq'`..
Turns out we were expecting/processing `Status(resp='error')` msgs not
`BrokerdError` (i guess bc latter was only really being used in initial
`brokerd` msg responses and not for relay of actual provider clearing
engine failures?) and the case block match / logic wasn't really
correct. So this changes a few things:
- always do reverse `oid` lookups from `reqid`s if possible in error msg
handling case.
- add a new `Error` client-dialog msg (derived from `Status`) which we
now relay when `brokerd` sends a `BrokerdError` and no prior `Status`
can be found (when it is we still fill in appropriate fields from the
backend-error and just send back the last status msg like before).
- try hard to look up the original `Order.symbol: str` for client
broadcasting trying first using any `Status.req` and failing over to
embedded `.brokerd_msg` field lookups.
- drop the `Status.name = 'error'` from literal def.
Finally this is a reason to use our new `OrderDialogs` abstraction; on
order submission errors IB doesn't really pass back anything other then
the `orderId` and the reason so we have to conduct our own lookup for
a message to relay to the EMS..
So, for every EMS msg we send, add it to the dialog tracker and then use
the `flows: OrderDialogs` for lookup in the case where we need to relay
said error. Also, include sending a `canceled` status such that the
order won't get stuck as a stale entry in the `emsd`'s own dialog table.
For now we just filter out errors that are unrelated from the stream
since there's always going to be stuff to do with live/history data
queries..
