Tyler Goodlet 2a59ccf1bb Incrementally yield to Qt loop to resize sidepanes
Since our startup is very concurrent there is often races where widgets
have not fully spawned before python (re-)sizing code has a chance to
run sizing logic and thus incorrect dimensions are read. Instead ensure
the Qt render loop gets to run in between such checks.

Also add a `open_sidepane()` mngr for creating a minimal form widget for
FSP subchart sidepanes which can be configured from an input `dict`.

Merge pull request #242 from pikers/simpler_quote_throttle_logic
Simplify throttle loop to a single `while` block
2021-12-09 16:21:35 -05:00
Tyler Goodlet bcc8d8a0d5 Simplify throttle loop to a single while block
This should in theory result in increased burstiness since we remove
the plain `trio.sleep()` and instead always wait on the receive channel
as much as possible until the `trio.move_on_after()` (+ time diffing
calcs) times out and signals the next throttled send cycle. This also is
slightly easier to grok code-wise instead of the `try, except` and
another tight while loop until a `trio.WouldBlock`. The only simpler
way i can think to do it is with 2 tasks: 1 to collect ticks and the
other to read and send at the throttle rate.

Comment out the log msg for now to avoid latency and add much more
detailed comments. Add an overrun log msg to the main sample loop.

Tyler Goodlet 4f899edcef Use a `pyqtgraph` dev branch pin (again)
There's lotsa movement on the project these days with stuff getting
improved, borked, fixed, rinse repeat. Might as well use a pin on our
fork so we can more easily hack on it and pull in latest features
piece-wise for testing.

Tyler Goodlet 5bf8e6a90e Use filled rect for current step
A `QRectF` is easier to make and draw (i think?) so use that and fill it
on volume events for decent sleek real-time look. Adjust the step array
generator to allow for an endpoints flag. Comment and/or clean out all
the old path filling calls that gave us perf issues..

Tyler Goodlet 0876d2f4fe Bleh, try a bunch of stuff for step filling
Turns out the performance of updating and refilling step curves > 1k ish
points is super slow :sadkek:. Disabling the fill basically returns
normal performance, so it seems maybe we'll stick with unfilled volume
"bars" for now. The other tricky bit is getting the path to extend and
fill which is particularly slow if you use the `QPainterPath.united()`
(what `+` set op does) operation which seems to require an entire redraw
of the curve each paint iteration. Removing the pixel buffer cache makes
things that much worse too..

One technique i tried was only setting a `._fill` flag when so many
datums are in view (< 1k as determined by the chart widget), and this
helps, but under high load (trade rates) you still see more lag then
without the fill which makes me say screw it and let's stick with
unfilled bars for now. Trying go to get performant filled curves will be
an exercise for an aspiring graphics eng :P

Tyler Goodlet e4e1b4d64a Invert 'c' (connection) array
In latest `pyqtgraph` it seems there's a discrepancy
since `function.arrayToQPath()` was reworked and now
we need to *not* connect the last point for each bar.

Tyler Goodlet ea9b66d1c3 Hotfix: open a tractor context to fsps...
The prior PR for fixing fsp array misalignment also added
`tractor.Context` usage which wasn't reflected in the graphics update
loop (newer code added it but the prior PR was factored from path
dependent history) and thus was broken. Further in newer work we don't
have fsp actors actually stream value updates since the display loop can
already pull from the source feed and update graphics at a preferred
throttle rate.  Re-enabled the fsp stream sending here by default until
that newer only-throttle-pull-from-source code is landed in the display
loop.
