Tyler Goodlet c94c53286b `FastAppendCurve`: Only render in-view data if possible
More or less this improves update latency like mad. Only draw data in
view and avoid full path regen as much as possible within a given
(down)sampling setting. We now support append path updates with in-view
data and the *SPECIAL CAVEAT* is that we avoid redrawing the whole curve
**only when** we calc an `append_length <= 1` **even if the view range
changed**. XXX: this should change in the future probably such that the
caller graphics update code can pass a flag which says whether or not to
do a full redraw based on it knowing where it's an interaction based
view-range change or a flow update change which doesn't require a full
path re-render.

Tyler Goodlet 7e1ec7b5a7 Incrementally update flattend OHLC data
After much effort (and exhaustion) but failure to get a view into our
`numpy` OHLC struct-array, this instead allocates an in-thread-memory
array which is updated with flattened data every flow update cycle.

I need to report what I think is a bug to `numpy` core about the whole
view thing not working but, more or less this gets the same behaviour
and minimizes work to flatten the sampled data for line-graphics drawing
thus improving refresh latency when drawing large downsampled curves.

Update the OHLC ds curve with view aware data sliced out from the
pre-allocated and incrementally updated data (we had to add a last index
var `._iflat` to track appends - this should be moved into a renderer
eventually?).

Tyler Goodlet 599c77ff84 Port ui components to use flows, drop all late assignments of shm 2022-06-05 22:13:08 -04:00
Tyler Goodlet c097016fd2 Add new `ui._flows` module
This begins the removal of data processing / analysis methods from the
chart widget and instead moving them to our new `Flow` API (in the new
module introduce here) and delegating the old chart methods to the
respective internal flow. Most importantly is no longer storing the
"last read" of an array from shm in an internal chart table (was
`._arrays`) and instead the `ShmArray` instance is passed as input and
stored in the `Flow` instance. This greatly simplifies lookup logic such
that the display loop now doesn't have to worry about reading shm, it
can be done by internal graphics logic as desired. Generally speaking,
all previous `._arrays`/`._graphics` lookups are now delegated to the
entries in the chart's `._flows` table.

The new `Flow` methods are generally better factored and provide more
detailed output regarding data-stream <-> graphics inter-relations for
the future purpose of allowing much more efficient update calls in the
display loop as well as supporting low latency interaction UX.

The concept here is that we're introducing an intermediary layer that
ties together graphics and real-time data flows such that widget code is
oriented around plot layout and the flow apis are oriented around
real-time low latency updates and providing an efficient high level
metric layer for the UX.

The summary api transition is something like:
- `update_graphics_from_array()` -> `.update_graphics_from_flow()`
- `.bars_range()` -> `Flow.datums_range()`
- `.bars_range()` -> `Flow.datums_range()`

Tyler Goodlet 78b9333bcd Expect `list` of ports in `ib.ports` section
Given that naming the port map is mostly pointless, since accounts can
be detected once the client connects, just expect a `brokers.toml` to
define a simple sequence of port numbers. Toss in a warning for using
the old map/`dict` style.

Tyler Goodlet 06832b94d4 Add vnc password auth, connection reset logic
Now that we have working client auth thanks to:
https://github.com/barneygale/asyncvnc/pull/4 and related issue,
we can use a pw for the vnc server, though we should eventually
auto-generate a random one from a docker super obviously.

Add logic to the data reset hack loop to do a connection reset after
2 failed/timeout attempts at the regular data reset. We need to also add
this logic around reconnectionn events that are due to the host
network connection: aka roaming that's faster then timing logic
builtin to the gateway.

Tyler Goodlet a5389beccd Rejig scan loop for flaky TCP connects, better caching
`ib-gw` seems particularly fragile to connections from clients with the
same id (can result in weird connect hangs and even crashes) and
`ib_insync` doesn't handle intermittent tcp disconnects that
well..(especially on dockerized IBC setups). This adds a bunch of
changes to our client caching and scan loop as well a proper
task-locking-to-cache-proxies so that,

- `asyncio`-side clients aren't double-loaded/connected even when
  explicitly trying to reconnect repeatedly with a given client to work
  around the unreliability of the `asyncio.Transport` design in
  `ib_insync`.
- we can use `tractor.trionics.maybe_open_context()` to lock the `trio`
  side from loading more then one `Client` on the `asyncio` side and
  instead on cache hits only making a new `MethodProxy` around the
  reused `asyncio`-side client (since each `trio` task needs its own
  inter-task msg channel).
- a `finally:` block teardown on all clients loaded in the scan loop
  avoids stale connections.
- the connect params are now exposed as named args to
  `load_aio_clients()` can be easily controlled from caller code.

Oh, and we properly hooked up the internal `ib_insync` logging to our
own internal schema - makes it a lot easier to debug wtf is going on XD

Tyler Goodlet a96f1dec3a Proxy heaven, choose one "preferred data client"
In order to expose more `asyncio` powered `Client` methods to endpoint
task-code this adds a more extensive and layered set of `MethodProxy`
loading routines, in dependency order these are:
- `load_clients_for_trio()` a `tractor.to_asyncio.open_channel_from()`
  entry-point factory for loading all scanned clients on the `asyncio` side
  and delivering them over the inter-task channel to a `trio`-side task.
- `get_preferred_data_client()` a simple client instance loading routine
  which reads from the users `brokers.toml -> `prefer_data_account:
  list[str]` which must list account names, in priority order, that are
  acceptable to be used as the main "data connection client" such that
  only one of the detected clients is used for data (whereas the rest
  are used only for order entry).
- `open_client_proxies()` which delivers the detected `Client` set
  wrapped each in a `MethodProxy`.
- `open_data_client()` which directly delivers the preferred data client
  as a proxy for `trio` tasks.
- update `open_client_method_proxy()` and `open_client_proxy` to require
  an input `Client` instance.

Further impl details:
- add `MethodProxy._aio_ns` to ref the original `asyncio` side proxied instance
- add `Client.trades()` to pull executions from the last day/session
- load proxies inside `trades_dialogue` and use the new `.trades()`
  method to try and pull a fill ledger for eventual correct pp price
  calcs (pertains to #307)..

sure we need this for the moment (or at all) anyway.

Tyler Goodlet a79a99fc71 Add working, template docker setup for `ib-gw`
Based on the now defunct project @
https://github.com/waytrade/ib-gateway-docker

Adds a `docker-compose.yml` and necessary gateway and `IBC` config
files to make it possible to spin up a local gateway on localhost:4002
and connect to it without issue using `ib_insync`.

Next up, we'll want to,
- automated the equivalent docker-compose steps using our
  `.data._ahab` supervisor system
- probably simplify and roll our own container (likely alpine or nixos
  based) which drops uneeded deps (`socat`, vnc) and adds `xdotool`.
- allow for API socket mapping to just be pulled direct from
  a user's `brokers.toml` and we'll just pass that direct to `IBC`'s
  config.
