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.
Handle new API field per 2025-12-02 update.
(this patch was generated in some part by [`claude-code`][claude-code-gh])
[claude-code-gh]: https://github.com/anthropics/claude-code
Lol, a cheeky unforeseen bug due to TOML's lack of a null type and
thinking i can render an `Optional` field on a `msgspec.Struct`
(defaulted to `None`) the `binance.symcache.toml` cache file..
I didn't catch this when i first updated to the 3.1 API in f7caa75228
because i never did a cache-files flush.. lesson learned and we **really
need tests for this**!!
Such that the next time i inevitably must debug the some order-request
error status or precision discrepancy, i have the mkt-symbol branch
ready to go. Also, switch to `'action': 'buy'|'sell' as action,` style
`case` matching instead of the post-`if` predicate style.
Using `tractor.trionics.collapse_eg()` as needed and doing
some renames, in similar style as elsewhere:
- `pcs` -> `rent_cs`,
- `n` -> `tn` for nursery handles,
Also,
- tweak the `._reconnect_forever()` while loop to use the
(also) `trio`-internal
`mc_state: trio._channel.MemoryChannelState = snd._state` instead
of `snd._close` to poll for open send/receive consumer task counts
since,
1. it seems more reliable then using the `snd._closed`,
2. there's no other way to access the info.. afaik?
- handle `ConnectionRejected` explicitly alongside handshake-errs as
a retry case.
- add a base-exc handler which `.exception()` reports the reconnect
attempt failure explicitly.
- drop some lingering `Optional` usage.
Namely changes for the `registry_addrs: list`, enable_transports: list`
and related `tractor._addr` primitive requirements.
Other updates include,
- passing `maybe_enable_greenback=True`,
- additional exc logging around `pikerd` syncing/booting,
- changing to newer `Context.wait_for_result()`,
- dropping (unnecessary?) `maybe_open_crash_handler()` around `pikerd` ep.
Topically, throughout various (seemingly) console-UX-affecting or benign
spots in the code base; nothing that required more intervention beyond
things superficial. A few spots also include `trio.Nursery` ref renames
(always to something with a `tn` in it) and log-level reductions to
quiet (benign) console noise oriented around issues meant to be solved
long..
Note there's still a couple spots i left with the loose-ify flag because
i haven't fully tested them without using the latest version of
`tractor.trionics.collapse_eg()`, but more then likely they should flip
over fine.
Commit this change separate from the (original) broader set applied to
the entire code base since the `.deribit.api` mod contained changes from
upstream max-pain work (from our very own @nt) which caused a noticeable
conflict and intros un-required changes from his work to re-enable
`deribit` support.
Note the original commit, "69eac7bb Spurious first-draft of EG
collapsing", applied similar changes through the rest of the code base.
AGAIN, this mod's change is only being broken out to minimize upstream
change conflicts due to updates to the `deribit` backend done earlier in
time-history.
The root daemon, pikerd, needs to be adjusted to use diff default
registry addrs to also utilize non-TCP, but for now this gets us started
testing; so far so good B)
That is to use the new `tractor.msg.types.Aid` struct to pull the
`brokerd` info from the `tractor.Channel.aid: Aid` attr as well as more
generally handling the new `Channel.raddr.proto_key: str` and no longer
assuming a TCP IPC transport; this per the recent `tractor.ipc`
subsys which adds multi-IPC-transports!
Downstream tweaks to match,
- use an "opt-in" field set to display in the `brokerd` info pane in
`.ui._feedstatus.mk_feed_label()`.
|_ also add some todos and drop some seemingly unneeded form sizing
calcs?
- tweak `.ui._label` to allow not using markdown, though ended up not
doing that since it looked too plain..
Using `tractor.trionics.collapse_eg()` as needed to avoid, at the least,
crash-worthy (in debug-mode REPL-ing terms) nested cancellation egs that
exhibit on SIGINT/ctl-c of each "app" (chart & daemon).
Also a bit of renaming of all `trio.Nursery`s to `tn`, the new "task
nursery" shorthand-var-name being used in all our other `tractor`
related projects.
Since we're not quite yet using automatic typed msging from
`tractor`/`msgspec` (i.e. still manually decoding order ctl msgs from
built-in types..`dict`s still not `msgspec.Struct`) this adds the
appropriate typecasting ops to ensure the required precision is attained
prior to processing and/or submission to a brokerd backend service.
For the `.clearing._ems`,
- flip all `trigger_price` previously presumed to be `float` to just
the field-identical `price: Decimal` and ensure we cast to `float`
for any `trigger_price` usage, like before passing to `mk_check()`.
For `.ui.order_mode.OrderMode`,
- add a new `.curr_mkt: MktPair` convenience property to get the
chart-active value.
- ensure we always use the `.curr_mkt.quantize() -> Decimal` before
setting any IPC-msg's `.price` field!
- always cast `float(Order.price)` before use in setting line-levels.
- don't bother setting `Order.symbol` to a (now fully removed) `Symbol`
instance since it's not really required-for-use anywhere; leaving it
a `str` (per the type-annot) is fine for now?
By re-typing to a `.price: Decimal` field on both legs of the EMS.
It seems we must do it ourselves since,
- these msg's (fields) are relayed through the clearing engine to each
`brokerd` backend and,
- bc many (if not all) of those backends `.broker`-clients (nor their
encapsulated "brokerage services") **are not** doing any
precision-truncation themselves.
So, for now, instead we opt to expect rounding at the source. This means
we will explicitly require casting to/from `float` at the line-graphics
interface to the order-clearing-engine (as implemented throughout
`.ui.order_mode.OrderMode`); and this is coming shortly.
Buncha updates and improvements,
- adjust sub-namespace imports according to console warnings.
- iterate all detected screens in a loop and instead report which is the
primary and the current.
- type annotate all vars where non-obvious, particularly the`Qt` refs.
