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..
