## Human instructions and evidence
|
||
|
|
|
||
|
|
Fix silent IB socket loss after network roaming, reported as
|
||
|
|
`[Errno 104] Connection reset by peer`. Also investigate a live
|
||
|
|
MNQ accounting crash in `emit_pp_update()` with empty normalized
|
||
|
|
ledger entries. The human supplied debugger evidence that a commission
|
||
|
|
for execution 4261 was paired with execution 4262 on the same contract
|
||
|
|
and account, and explicitly requested implementation and regression
|
||
|
|
tests. They asked to retain the roaming task and continue working
|
||
|
|
through follow-up messages.
|
||
|
|
|
||
|
|
## Generated changes
|
||
|
|
|
||
|
|
> `git diff HEAD -- piker/brokers/ib/broker.py`
|
||
|
|
|
||
|
|
Preserve the callback-supplied fill with its commission. Track positions
|
||
|
|
by account and contract ID and pending commissioned fills by execution.
|
||
|
|
Reject mismatched commission/execution IDs. Propagate socket closure
|
||
|
|
instead of returning normally from the trade-event bridge.
|
||
|
|
|
||
|
|
> `git diff HEAD -- piker/brokers/ib/ledger.py`
|
||
|
|
|
||
|
|
Keep Execution.execId authoritative when flattening commission fields.
|
||
|
|
|
||
|
|
> `git diff HEAD -- piker/brokers/ib/api.py`
|
||
|
|
|
||
|
|
Relay the authoritative disconnected event as ConnectionError, retaining
|
||
|
|
the most recent API error text, and raise it from the proxy reader.
|
||
|
|
Automatic session reconnect/resynchronization remains unimplemented.
|
||
|
|
|
||
|
|
> `git diff HEAD -- tests/test_ib_trade_events.py tests/test_ib_method_proxy.py`
|
||
|
|
|
||
|
|
Cover overlapping executions, zero commissions, position-before/after
|
||
|
|
commission ordering, empty commission IDs, and eventkit socket loss.
|
||
|
|
Nine focused tests passed, including the actual eventkit callback
|
||
|
|
bridge and its disconnect exception. Focused Ruff checks and
|
||
|
|
`git diff --check` also passed.
