Including changing to `LinkedSplits.mkt: MktPair` and adding an explicit
setter method for setting it and being sure that nothing breaks
in the display system init!
For this commit we leave in warning access to `LinkedSplits.symbol` but
will remove in following commit.
Only stuff left was the allocator stuff. Drop the top level subpkg
exports and finally kill off the awkwardly named
`Symbol.lot_size_digits` properties XD
Expose a bunch more util funcs at subpkg top level, do some typing in
allocator method internals.
Contract matching in live setup was borked; switch to
`MktPair.dst.atype` matching, don't override the `cmdty` "venue" (a
weird special case) in `get_mkt_info()` otherwise lookup will fail..
Stash it for now in the (now mutable by default) `.shm_write_opts` and
have the new `Flume._has_vlm: bool` (only set to false internally by
feed layer) which can be read via new public `.has_vlm()` predicate.
Move out the old `.ui/_fsp` helper logic to this flume method.
Avoids the really sloppy flag passing to `open_pikerd()` and allows for
separation of the individual docker daemon starts.
Also add a new `root_conf() -> Path` fixture which will open and load
the `dict` for the new root `conf.toml` file.
Using the new `._ahab.start_ahab_service()` mngr of course, and now
support user config overrides (such that our defaults can be modified by
a keen user, say using a config file, or for testing). This is where the
functionality moved out of the `pikerd` init has been moved - instead of
being triggered by bool flag inputs to that factory.
For marketstore actually support overriding the entire yaml config via
runtime `_yaml_config_str: str` formatting with any passed user dict,
primarily focussing on supporting override of the sockaddrs for testing.
Allows for using the `Services.cancel_service()` api for explicit
cancellation in tests and eventually for remote teardown. Change
`.start_ahab()` to an `@acm` `start_ahab_service()` and just yield back
the same values we were returning prior. Also fix the logging (level) to
actually reflect what's passed in - we weren't using the correct name
/ instance from the `.sevice` subpkg..
Since `.config.load()` was changed to not touch conf files by default
(without explicitly setting `touch_if_dne: bool`), this ensures both the
global module value is set and the `brokers.toml` file exists before
every test.
`Flume.mkt.fqme` might not be exactly the same as the local
version now since we've had to add some hacks to certain backends
(cough ib) to handle `MktPair.src` not being set as an `Asset` (yet).
Since `open_trade_ledger()` now requires a sort we pass in a combo of
the std `pendulum.parse()` for API records and a custom flex parser for
flex entries pulled offline.
Add special handling for `MktPair.src` such that when it's a fiat (like
it should always be for most legacy assets) we try to get the fqme
without that `.src` token (i.e. not mnqusd) to avoid breaking
roundtripping of live feed requests (due to new symbology) as well as
the current tsdb table key set..
Do a wholesale renaming of fqsn -> fqme in most of the rest of the
backend modules.
Turns out that reading **and** writing with `tomlkit` is just wayya slow
for large documents like ledger files so move to using the `tomli`
sibling pkg `tomli-w` which seems to much improve on the latency, though
obviously longer run we're likely going to want:
- a better algorithm for only back loading records using as little
history as possible
- a different serialization format for production maybe something
like apache parquet?
The only issue with using a non-style-preserving writer is that we don't
necessarily get TOML conf ordering for free (without first ordering it
ourselves), and thus this patch also adds much more general date-time
sorting machinery which is now **required** when using
`open_trades_ledger()` via a `tx_sort: Callable`. By default we now
provide `.accounting._ledger.iter_by_dt()` (exposed in the subpkg mod)
which conducts dynamic "datetime key detection" based parsing of records
based on a `parsers: dict[str, Callabe]` input table. The default should
handle most use cases including all currently supported live backends
(kraken, ib) as well as our paper engine ledger-records format.
Granulars:
- adjust `Position.iter_clears()` to use new `iter_by_dt(key=lambda ..)`
signature.
- add `tomli-w` to setup and our `tomlkit` fork to requirements file.
- move `.write_config()` to bottom of class defn.
- fix closed pos popping to not error if pp was already popped..
Since porting all backends to the new `FeedInit` + `MktPair` + `Asset`
style init, we can now just directly pass a `MktPair` instance to the
history endpoint(s) since it's always called *after* the live feed
`.stream_quotes()` ep B)
This has a lot of benefits including allowing brokerd backends to have
more flexible, pre-processed market endpoint meta-data that piker has
already validated; makes handling special cases in much more straight
forward as well such as forex pairs from legacy brokers XD
First pass changes all crypto backends to expect this new input, ib will
come next after handling said special cases..
Since most (legacy) stock brokers design their symbology without
including the target exchange's source asset name - normally a fiat
currency like USD - this adds an option for rendering market endpoints
without that token for simpler use in backends for such brokers.
As an example IB doesn't expect a `mnq/usd.cme.ib` symbol and instead
presumes that since the CME lists all assets in USD then the source
asset is implied.
Impl details:
- add `MktPair.pair: str` which replaces `.key` as a better name.
- offer a `without_src: bool` to a new `.get_fqme()` getter method
which will render everything the same minus the src token.
- expose the new flag through both the new `.get_fqme()` and
`.get_bs_fqme()` methods and wrap those both under the original
property names `.bs_fqme` and `.fqme`.
Previously the subscription response handling was a bit sloppy what with
ignoring the welcome msg; this now correctly expects the correct startup
sequence. Also this avoids warn logging on pong messages by expecting
them in the msg loop and further drops the `KucoinMsg` struct and
instead changes the msg loop to expect `dict`s and only cast to structs
on live feed msgs that we actually process/relay.
