For `[ib]` adjust content to match changes to the
`dockering/ib/README.rst` and for `[deribit]` toss in the WIP options
related params for anyone who wants to play around with @nt's work.
Such that the `brokers.toml` can contain any of the following
<port> = dict|tuple styles,
```toml
[ib.vnc_addrs]
4002 = {host = 'localhost', port = 5900, pw = 'doggy'} # host, port, pw
4002 = {host = 'localhost', port = 5900} # host, port, pw
4002 = ['localhost', 5900] # host, port, pw
```
With the first line demonstrating a vnc-server password (as normally set
via a `.env` file in the `dockering/ib/` subdir) with the `pw =` field.
This obviously removes the hardcoded `'doggy'` password from prior.
Impl details in `.brokers.ib._util`:
- pass the `ib.api.Client` down into `vnc_click_hack()` doing all config
reading within and removing host, port unpacking in the callingn
`data_reset_hack()`.
- also pass the client `try_xdo_manual()` and comment (with plans to
remove) the recently added localhost-only fallback section since
we now have a fully working py vnc client again with `pyvnc` B)
- in `vnc_click_hack()` match for all the possible config line styles
and,
* pass any `pw` field to `pyvncVNCConfig`,
* continue matching host, port without password,
* fallthrough to raising a val-err when neither ^ match.
For the new github image, a high-level look at its basic
features/usage/docs and prosing around our expected default usage with
the `piker.brokers.ib` backend.
It actually works for vncAuth(2) (thank god!) which the previous
`asyncvnc` **did not**, and seems to be mostly based on the work
from the `asyncvnc` author anyway (so all my past efforts don't seem to
have been in vain XD).
NOTE, the below deats ended up being factored in earlier into the
`pyproject.toml` alongside nix(os) support needed for testing and
landing this history. As the such, the comments are the originals but
the changes are not.
Deats,
- switch to `pyvnc` async API (using `asyncio` again obvi) in
`.ib._util._vnc_click_hack()`.
- add `pyvnc` as src installed dep from GH.
- drop `asyncvnc` as dep.
Other,
- update `pytest` version range to avoid weird auto-load plugin exposed
by `xonsh`?
- add a `tool.pytest.ini_options` to project file with vars to,
- disable that^ `xonsh` plug using `addopts = '-p no:xonsh'`.
- set a `testpaths` to avoid running anything but that subdir.
- try out the `'progress'` style console output (does it work?).
Such that if/when the `push()` ticker callback (closure) errors
internally, we actually eventually bubble the error out-and-up from the
`asyncio.Task` and from there out the `.to_asyncio.open_channel_from()` to
the parent `trio.Task`..
It ended up being much more subtle to solve then i would have liked
thanks to,
- whatever `Ticker.updateEvent.connect()` does behind the scenes in
terms of (clearly) swallowing with only log reporting any exc raised
in the registered callback (in our case `push()`),
- `asyncio.Task.set_excepion()` never working and instead needing to
resort to `Task.cancel()`, catching `CancelledError` and re-raising
the stashed `maybe_exc` from `push()` when set..
Further this ports `.to_asyncio.open_channel_from()` usage to use
the new `chan: tractor.to_asyncio.LinkedTaskChannel` fn-sig API, namely
for `_setup_quote_stream()` task. Requires the latest `tractor` updates
to the inter-eventloop-chan iface providing a `.set_nowait()` and
`.get()` for the `asyncio`-side.
Impl deats within `_setup_quote_stream()`,
- implement `push()` error-bubbling by adding a `maybe_exc` which can be
set by that callback itself or by its registering task; when set it is
both,
* reported on by the `teardown()` cb,
* re-raised by the terminated (via `.cancel()`) `asyncio.Task` after
woken from its sleep, aka "cancelled" (since that's apparently one
of the only options.. see big rant further todo comments).
- add explicit error-tolerance-tuning via a `handler_tries: int` counter
and `tries_before_raise: int` limit such that we only bubble
a `push()` raised exc once enough tries have consecutively failed.
- as mentioned, use the new `chan` fn-sig support and thus the new
method API for `asyncio` -> `trio` comms.
- a big TODO XXX around the need to use a better sys for terminating
`asyncio.Task`s whether it's by delegating to some `.to_asyncio`
internals after a factor-out OR by potentially going full bore `anyio`
throughout `.to_asyncio`'s impl in general..
- mk `teardown()` use appropriate `log.<level>()`s based on outcome.
Surroundingly,
- add a ton of doc-strings to mod fns previously missing them.
- improved / added-new comments to `wait_on_data_reset()` internals and
anything changed per ^above.
NOTE, resolved conflicts on `piker/brokers/ib/feed.py` due to
`brokers_refinery` commit:
d809c797 `.brokers.ib.feed`: better `tractor.to_asyncio` typing and var naming throughout!
Such that we can avoid other (pretty unreliable) "alternative" checks to
determine whether a real-time quote should be waited on or (when venue
is closed) we should just signal that historical backfilling can
commence immediately.
This has been a todo for a very long time and it turned out to be much
easier to accomplish than anticipated..
Deats,
- add a new `is_current_time_in_range()` dt range checker to predicate
whether an input range contains `datetime.now(start_dt.tzinfo)`.
- in `.ib.feed.stream_quotes()` add a `venue_is_open: bool` which uses
all of the new ^^ to determine whether to branch for the
short-circuit-and-do-history-now-case or the std real-time-quotes
should-be-awaited-since-venue-is-open, case; drop all the old hacks
trying to workaround not figuring that venue state stuff..
Other,
- also add a gpt5 composed parser to `._util` for the
`ib_insync.ContractDetails.tradingHours: str` for before i realized
there was a `.tradingSessions` property XD
- in `.ib_feed`,
* add various EG-collapsings per recent tractor/trio updates.
* better logging / exc-handling around ticker quote pushes.
* stop clearing `Ticker.ticks` each quote iteration; not sure if this
is needed/correct tho?
* add masked `Ticker.ticks` poll loop that logs.
- fix some `str.format()` usage in `._util.try_xdo_manual()`
NOTE, resolved conflicts on `piker/brokers/ib/feed.py` due to
rebasing onto up stream `brokers_refinery` commit,
d809c797 `.brokers.ib.feed`: better `tractor.to_asyncio` typing and var naming throughout
You'd think they could be bothered to make either a "log" or "warning"
msg type instead of a `type='error'`.. but alas, this attempts to detect
all such "warning"-errors and never proxy them to the clearing engine
thus avoiding the cancellation of any associated (by `reqid`)
pre-existing orders (control dialogs).
Also update all surrounding log messages to a more multiline style.
Since apparently porting to the new docker container enforces using
a vnc password and `asyncvnc` seems to have a bug/mis-config whenever
i've tried a pw over a wg tunnel..?
Soo, this tries out the old `i3ipc`-win-focus + `xdo` click hack when
the above fails.
Deats,
- add a mod-level `try_xdo_manual()` to wrap calling
`i3ipc_xdotool_manual_click_hack()` with an oserr handler, ensure we
don't bother trying if `i3ipc` import fails beforehand tho.
- call ^ from both the orig case block and the failover from the
vnc-client case.
- factor the `+no_setup_msg: str` out to mod level and expect it to be
`.format()`-ed.
- refresh todo around `asyncvnc` pw ish..
- add a new `i3ipc_fin_wins_titled()` window-title scanner which
predicates input `titles` and delivers any matches alongside the orig
focused win at call time.
- tweak `i3ipc_xdotool_manual_click_hack()` to call ^ and remove prior
unfactored window scanning logic.
