Tried a couple libs and ended up sticking with `rich` (since it's the
sibling lib to `typer`) but also (initially) implemented a version with
`blessings` that I ended up commenting out (and will likely remove).
Adjusted the CLI I/O a slight bit as well:
- require a fully qualified account name of the form:
`<brokername>.<accountname>` and error on non-matching input.
- dump positions summary lines as humanized size, ppu and cost basis
values per line.
When processing paper trades ledgers we normally won't have specific
`MktPair` info for the backend market we're simulating, as such we
need to look up this info when updating pps.toml files such that we
get precision info correct (particularly in the case of cryptos!) and
can also run paper ledger processing without running the simulated
clearing loop. In order to make it happen we lookup any `get_mkt_info()`
ep on the backend and pass the output to the `force_mkt` input of the
`PpTable.update_from_trans()` method.
This will (likely) act as a new backend query endpoint for other `piker`
(client) code to lookup `MktPair` info from each backend. To start it
also returns the backend-broker's local `Pair` (or wtv other type) as
well.
The main motivation for this is for our paper engine which can require
the mkt info when processing paper-trades ledgers which do not contain
appropriate info to compute position metrics.
Instead of stripping the broker part just use the full fqme for all
`Transaction.bs_mktid: str` values since it makes indexing the `PpTable`
much easier with less key mangling..
Change the root-service-task entrypoint to accept the level and
setup a console log as is now expected for all sub-services. Cast all
backend delivered startup `BrokerdPosition` msgs and log them to
console.
If you want a sub-actor to write console logs (with the right level) the
`get_console_log()` call has to be made somewhere during service task
startup. Previously this wasn't well formalized nor used (depending on
daemon) so passing `loglevel` to the service's root-task-endpoint (eg.
`_setup_persistent_brokerd()`) encourages that the daemon's logging is
configured during init according to the spawner's requesting logging
config. The previous `get_console_log()` call happening inside
`maybe_spawn_daemon()` wasn't actually doing anything in the target
daemon XD, so obviously remove that and instead passthrough loglevel
to the ctx endpoints and service manager methods.
More or less we need to be able to audit not only simple "make trades
check pps.toml files" tests (which btw were great to get started!).
We also need more sophisticated and granular order mgmt and service
config scenarios,
- full e2e EMS msg flow verification
- multi-client (dis)connection scenarios and/or monitoring
- dark order clearing and offline storage
- accounting schema and position calcs detailing
As such, this is the beginning to "modularlizingz" the components needed
in the test harness to this end by breaking up the `OrderClient` control
flows vs. position checking logic so as to allow for more flexible test
scenario cases and likely `pytest` parametrizations over different
transaction sequences.
Not sure how this worked before but we need to also override the
`piker._config_dir: Path` in the root actor when running in `pytest`; my
guess is something in the old test suite was masking this problem after
the change to passing the dir path down through the runtime vars via
`tractor`?
Also this drops the ems related fixtures/factories since they're
specific enough to define in the clearing engine tests directly.
Turns out we don't hookup our eventkit handler until after the
`load_aio_clients()` is complete, which means we can't get
`ib_insync.Client.apiError` events unless inside the asyncio side task.
So I guess try to report any such errors during API scan (note the
duplicate client id case is a special one from ibis itself) even though
we're not going to catch them trio side. The hack to work around this is
to just increment the client id value with the `connect_retries` led `i`
value even though that will break on more then 3 clients attached to an
API endpoint lul ..
Further adjustments that were to the end of trying to fix this proper:
- add `remove_handler_on_err()` cm to disconnect a handler when the trio
side of the channel closes.
- actually connect to client api erros in our `Client.inline_errors()`
- increase connect timeout to a sec.
- change the trio-asyncio proxy response-msg loop over to `match:`
syntax and raise on unhandled msgs from eventkit handlers.
We previously only offered a sync API (which was recently renamed to
`.<meth>_nowait()` style) since initially all order control was from our
`OrderMode` Qt driven UI/UX. This adds the equivalent async methods for
both testing as well as eventual auto-strat driven control B)
Also includes a bunch of renaming:
- `OrderBook` -> `OrderClient`.
- better internal renaming of the client's mem chan vars and add a ref
`._ems_stream: tractor.MsgStream`.
- drop `get_orders()` factory, just always check for the actor-global
instance and always set the ems stream on that client (in case old one
was closed).
This will end up being super handy for testing our accounting subsystems
as well as providing unified and simple cli utils for managing ledgers
and position tracking. Allows loading the paper boi without starting
a data feed and instead just trigger ledger and pps loading without
starting the entire clearing engine.
Deatz:
- only init `PaperBoi` and start clearing loop (tasks) if a non-`None`
fqme is provided, ow just `Context.started()` the existing pps msgs
as loaded from the ledger.
- always update both the ledger and pp table on startup and pass
a single instance of each obj to the `PaperBoi` for reuse (without
opening and closing backing config files since we now have
`.write_config()`).
- drop the global `_positions` dict, it's not needed any more if we use
a `PaperBoi.ppt: PpTable` which persists with the engine actor's
lifetime.
Add a new `class TransactionLedger(collections.UserDict)` for managing
ledger (files) from a `dict`-like API. The main motivations being easy
conversion between `dict` <-> `Transaction` obj forms as well as dynamic
(toml) file updates via a set of methods:
- `.write_config()` to render and write state to the local toml file.
- `.iter_trans()` to allow iterator style conversion to `Transaction`
form for each entry.
- `.to_trans()` for the dict output from the above.
Some adjustments to `Transaction` namely making `.sym/.sys` optional for
now so that paper engine entries can be loaded (offline) without
connecting to the emulated broker backend. Move to using `pathlib.Path`
throughout for bootyful toml file mgmt B)
When loading a `Position` from a pps file we might not have the entire
`MktPair` field-set loaded (though going forward that shouldn't really
ever happen except in the case of a legacy `pps.toml`), in which case we
can check if the `.fqme: str` value loaded from the transaction is
longer and use that instead - presuming it must have more mkt meta-data
filled out.
Also includes some more `fqsn` -> `fqme` renames.
Been meaning to do this port for a while and since it makes passing
around file handles (presumably alongside the in mem obj form) a lot
simpler/nicer and the implementations of all the config file handling
much more terse with less presumptions about the form of filename/dir
`str` values all over the place B)
moar technically, let's us:
- drop remaining `.config` usage of `os.path`.
- return `Path`s from most routines.
- adds a special case to `get_conf_path()` such that if the input name
contains a `pps.` pattern, we avoid validating the name; this is going
to be used by new `.accounting.open_pps()` code which will instead
write a separate TOML file for each account B)
Previous we were re-processing all ledgers for every position msg
received from the API, per client.. Instead do that once in a first pass
and drop all key-miss lookups for `bs_mktid`s; it should never happen.
Better typing for in-routine vars, convert pos msg/objects to `dict`
prior to logging so it's sane to read on console. Skip processing
specifically option contracts for now.
