Tyler Goodlet 9951e1d4c9 Fix shm index update race
There was a lingering issue where the fsp daemon would sync its shm
array with the source data and we'd set the start/end indices to the
same value. Under some races a reader would then read an empty `.array`
which it wasn't expecting. This fixes that as well as tidies up the
`ShmArray.push()` logic and adds a temporary check in `.array` for zero
length if the array hasn't been written yet.

We can now start removing read array length checks in consumer code
and hopefully no more races will show up.

Revert to old shm "last" meaning last row

Tyler Goodlet 4c9e5feace Expose dollar volume to fsp engine
It can now be declared inside an fsp config dict under the name
`dolla_vlm`. We still need to offer an engine control that zeros
the newest sample value instead of copying from the previous.

This also litters the engine code with `pyqtgraph` profiling to see if
we can improve startup times - likely it'll mean pre-allocating a small
fsp daemon cluster at startup.

Tyler Goodlet 224c01e43e Spawn and cache an fsp cluster ahead of time
Use a fixed worker count and don't respawn for every chart, instead
opting for a round-robin to tasks in a cluster and (for now) hoping for
the best in terms of trio scheduling, though we should obviously route
via symbol-locality next. This is currently a boon for chart spawning
startup times since actor creation is done AOT.

Additionally,
- use `zero_on_step` for dollar volume
- drop rsi on startup (again)
- add dollar volume (via fsp) along side unit volume
- litter more profiling to fsp chart startup sequence
- pre-define tick type classes for update loop

Tyler Goodlet 853e8d4466 Process framed ticks by type in main graphics loop
We are already packing framed ticks in extended lists from
the `.data._sampling.uniform_rate_send()` task so the natural solution
to avoid needless graphics cycles for HFT-ish feeds (like binance) is
to unpack those frames and for most cases only update graphics with the
"latest" data per loop iteration. Unpacking in this way also lessens
nested-iterations per tick type.

Btw, this also effectively solves all remaining issues of fast tick
feeds over-triggering the graphics loop renders as long as the original
quote stream is throttled appropriately, usually to the local display
rate.

Relates to #183, #192

Dirty deats:
- drop all per-tick rate checks, they were always somewhat pointless
  when iterating a frame of ticks per render cycle XD.
- unpack tick frame into ticks per frame type, and last of each type;
  the lasts are used to update each part of the UI/graphics by class.
- only skip the label update if we can't retrieve the last from from a
  graphics source array; it seems `chart.update_curve_from_array()`
  already does a `len` check internally.
- add some draft commented code for tick type classes and a possible
  wire framed tick data structure.
- move `chart_maxmin()` range computer to module level, bind a chart to
  it with a `partial.`
- only check rate limits in main quote loop thus reporting actual
  overages
- add in commented logic for only updating the "last" cleared price from
  the most recent framed value if we want to eventually (right now seems
  like this is only relevant to ib and it's dark trades: `utrade`).
- rename `_clear_throttle_rate` -> `_quote_throttle_rate`, drop
  `_book_throttle_rate`.

Tyler Goodlet e8cd1a0e83 Update fsps and overlays inside main OHLC chart update loop 2022-01-23 12:19:11 -05:00
Tyler Goodlet 96937829eb Factor FSP subplot update code into func
This is in prep toward doing fsp graphics updates from the main quotes
update loop (where OHLC and volume are done). Updating fsp output from
that task should, for the majority of cases, be fine presuming the
processing is derived from the quote stream as a source. Further,
calling an update function on each fsp subplot/overlay is of course
faster then a full task switch - which is how it currently works with
a separate stream for every fsp output. This also will let us delay
adding full `Feed` support around fsp streams for the moment while still
getting quote throttling dictated by the quote stream.

Going forward, We can still support a separate task/fsp stream for
updates as needed (ex. some kind of fast external data source that isn't
synced with price data) but it should be enabled as needed required by
the user.

Tyler Goodlet 4ea42a0a7e More prep for FSP feeds
The major change is moving the fsp "daemon" (more like wanna-be fspd)
endpoint to use the newer `tractor.Portal.open_context()` and
bi-directional streaming api.

There's a few other things in here too:
- make a helper for allocating single colume fsp shm arrays
- rename some some fsp related functions to be more explicit on their
  purposes
