Previously we would make the `ahabd` supervisor-actor sync to docker
container startup using pseudo-blocking log message processing.
This has issues,
- we're forced to do a hacky "yield back to `trio`" in order to be
"fake async" when reading the log stream and further,
- blocking on a message is fragile and often slow.
Instead, run the log processor in a background task and in the parent
task poll for the container to be in the client list using a similar
pseudo-async poll pattern. This allows the super to `Context.started()`
sooner (when the container is actually registered as "up") and thus
unblock its (remote) caller faster whilst still doing full log msg
proxying!
Deatz:
- adds `Container.cuid: str` a unique container id for logging.
- correctly proxy through the `loglevel: str` from `pikerd` caller task.
- shield around `Container.cancel()` in the teardown block and use
cancel level logging in that method.
With the addition of a new `elastixsearch` docker support in
https://github.com/pikers/piker/pull/464, adjustments were made
to container startup sync logic (particularly the `trio` checkpoint
sleep period - which itself is a hack around a sync client api) which
caused a regression in upstream startup logic wherein container error
logs were not being bubbled up correctly causing a silent failure mode:
- `marketstore` container started with corrupt input config
- `ahabd` super code timed out on startup phase due to a larger log
polling period, skipped processing startup logs from the container,
and continued on as though the container was started
- history client fails on grpc connection with no clear error on why the
connection failed.
Here we revert to the old poll period (1ms) to avoid any more silent
failures and further extend supervisor control through a configuration
override mechanism. To address the underlying design issue, this patch
adds support for container-endpoint-callbacks to override supervisor
startup configuration parameters via the 2nd value in their returned
tuple: the already delivered configuration `dict` value.
The current exposed values include:
{
'startup_timeout': 1.0,
'startup_query_period': 0.001,
'log_msg_key': 'msg',
},
This allows for container specific control over the startup-sync query
period (the hack mentioned above) as well as the expected log msg key
and of course the startup timeout.
Adds a `piker storage` subcmd with a `-d` flag to wipe a particular
fqsn's time series (both 1s and 60s). Obviously this needs to be
extended much more but provides a start point.
Since apparently the container we were using is totally borked on new
kernels and/or latest jvm, this move our old manual local-X-desktop script
back for use in `brokerd` backend code.
Adds a new `.brokers.ib._util` which contains the 2 methods and fails
over to this one when we can't connect to a VNC server. Also adjusts the
original in `scripts/ib_data_reset.py` to import and run the module code
as a script-program.
Also includes a retyping of `Client._pair: dict[str, Pair]` to look up
pair structs and map all alt-key-name-sets to each for easy precision
info lookup to set the `.sym` field for each transaction including for
on-chain transfers which kraken provides as an "asset decimals" field,
presumably pulled from the particular block-token's limitation info.
In order to support existing `pps.toml` files in the wild which don't
have the `asset_type, price_tick_size, lot_tick_size` fields, we need to
only optionally read them and instead expect that backends will write
the fields going forward (coming in follow patches).
Further this makes some small asset-size (vlm accounting) quantization
related adjustments:
- rename `Symbol.decimal_quant()` -> `.quantize_size()` since that is
explicitly what this method is doing.
- and expect an input `size: float` which we cast to decimal instead of
doing it inside the `.calc_size()` caller code.
- drop `Symbol.iterfqsns()` which wasn't being used anywhere at all..
Additionally, this drafts out a new replacement market-trading-pair data
type to eventually replace `.data._source.Symbol` -> `MktPair` which we
aren't using yet, but serves as the documentation-driven motivator ;)
and, it relates to https://github.com/pikers/piker/issues/467.
