Given it's a fairly simple yet useful abstraction, it makes sense to
offer this sub-sys alongside the core `tractor` runtime lib.
Without going into extreme detail on the impl changes (it'll come in
the commit that moves to the other repo) here is the high level summary:
------ - ------
- rename `Services` -> `ServiceMngr` and use an factory `@acm`
to guarantee a single-instance-per-actor using a niche approach for a
singleton object using a default keyword-arg B)
- the mod level `open_service_mngr()` and `get_service_mngr()` are the
new allocation/access API.
- add a `ServiceMngr.start_service()` method which does the work of both
spawning a new subactor (for the daemon) and uses its portal to start
the mngr side supervision task.
- open actor/task nurseries inside the `@acm` allocator.
Adjust other dependent subsystems to match:
------ - ------
- use `open_service_mngr()` when first allocated in `open_pikerd()`.
- use `get_service_mngr()` instead of importing the class ref inside
`.service.maybe_spawn_daemon()`, `.brokers._daemon.spawn_brokerd()`
and `.data._sampling.spawn_samplerd()` using a `partial` to pack in
the endpoint ctx kwargs (unpacked inside `.start_service()` XD).
Avoids the really sloppy flag passing to `open_pikerd()` and allows for
separation of the individual docker daemon starts.
Also add a new `root_conf() -> Path` fixture which will open and load
the `dict` for the new root `conf.toml` file.
Since `.config.load()` was changed to not touch conf files by default
(without explicitly setting `touch_if_dne: bool`), this ensures both the
global module value is set and the `brokers.toml` file exists before
every test.
More or less a complete rework which allows passing a detailed
clearing/fills input and allows for *not* rebooting the runtime / ems
between each position check.
Some further enhancements:
- use (unit) fractional sizes to simulate both the more realistic and
more "complex position calculation" case; since this is crypto.
- add a no-fqme-found test.
- factor cross-session/offline pos storage (pps.toml) checks into
a `load_and_check_pos()` helper which does all entry loading directly
from a provided `BrokerdPosition` msg.
- use the new `OrderClient.send()` async api.
More or less we need to be able to audit not only simple "make trades
check pps.toml files" tests (which btw were great to get started!).
We also need more sophisticated and granular order mgmt and service
config scenarios,
- full e2e EMS msg flow verification
- multi-client (dis)connection scenarios and/or monitoring
- dark order clearing and offline storage
- accounting schema and position calcs detailing
As such, this is the beginning to "modularlizingz" the components needed
in the test harness to this end by breaking up the `OrderClient` control
flows vs. position checking logic so as to allow for more flexible test
scenario cases and likely `pytest` parametrizations over different
transaction sequences.
Not sure how this worked before but we need to also override the
`piker._config_dir: Path` in the root actor when running in `pytest`; my
guess is something in the old test suite was masking this problem after
the change to passing the dir path down through the runtime vars via
`tractor`?
Also this drops the ems related fixtures/factories since they're
specific enough to define in the clearing engine tests directly.
Due to making ahabd supervisor init more async we need to be more
tolerant to mkts server startup: the grpc machinery needs to be up
otherwise a client which connects to early may just hang on requests..
Add a reconnect loop (which might end up getting factored into client
code too) so that we only block on requests once we know the client
connection is actually responsive.
