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.
Instead adjust `load_aio_clients()` to only reload clients detected as
non-loaded or disconnected (2 birds), and avoid use of the global module
table which could result in stale disconnected clients persisting on
multiple `brokerd` client reconnects, resulting in error.
Was broken since the `_adhoc_futes_set` rework a while back. Removes the
cmdty symbols from that set into a new one and fixes the contract
case block to catch `Contract(secType='CMDTY')` case. Also makes
`Client.search_symbols()` return details `dict`s so that `piker search`
will work again..
Allows for easier restarts of certain `trio` side tasks without killing
the `asyncio`-side clients; support via flag.
Also fix a bug in `Client.bars()`: we need to return the duration on the
empty bars case..
This allows the history manager to know the decrement size for
`end_dt: datetime` on the next query if a no-data / gap case was
encountered; subtract this in `get_bars()` in such cases. Define the
expected `pendulum.Duration`s in the `.api._samplings` table.
Also add a bit of query latency profiling that we may use later to more
dynamically determine timeout driven data feed resets. Factor the `162`
error cases into a common exception handler block.
When we get a timeout or a `NoData` condition still return a tuple of
empty sequences instead of `None` from `Client.bars()`. Move the
sampling period-duration table to module level.
If you spawn a brokerd set and no `ib` data feed was started (via our
`.data.feed.Feed` api) then there will be no active client loaded and
thus wont' be connected. So in these cases just return nothing, and
I guess we'll figure out real connection failures later?
Change `.find_contract()` -> `.find_contracts()` to allow multi-search
for so called "ambiguous" contracts (like for `Future`s) such that the
method now returns a `list` of tracts and populates the contract cache
with all specific tracts retrieved. Let it take in an (unvalidated)
contract that will be fqsn-style-tokenized such that it can be called
from `.search_symbols()` (though we're not quite yet XD).
More stuff,
- add `Client.parse_patt2fqsn()` which is an fqsn to token unpacker
built from the original logic in the old `.find_contract()`.
- handle fiat/forex pairs with the `'CASH'` sectype.
- add a flag to allow unqualified contracts to fail with a warning msg.
- populate the client's contract cache with all expiries of
an ambiguous derivative.
- allow `.con_deats()` to warn msg instead of raise on def-not-found.
- add commented `assert 0` which was triggering a debugger deadlock in
`tractor` which we still haven't been able to create a unit test for.
Since "flex reports" are only available for the current session's trades
the day after, this adds support for also collecting trade execution
records for the current session and writing them to the equivalent
ledger file.
Summary:
- add `trades_to_records()` to handle parsing both flex and API event
objects into a common record form.
- add `norm_trade_records()` to handle converting ledger entries into
`TradeRecord` types from the new `piker.pps` mod (coming in next
commit).
