Audit fixes across the ingestion stack: Observability - Move log_ingestion out of batch loops in poll_alarms and poll_parking (was emitting N cumulative log rows per run instead of one). - Add missing log_ingestion + t0 to poll_trips. - Count inserted via cur.rowcount instead of naive +=1 so ON CONFLICT DO NOTHING no longer inflates the metric. Resilience - SAVEPOINT-per-item added to poll_alarms, poll_live_positions, poll_trips, poll_parking so one bad row no longer aborts the batch (webhook handlers already had this; pollers were inconsistent). Performance - /pushgps and poll_track_list now use psycopg2.extras.execute_values with ON CONFLICT DO NOTHING — 10-50x write throughput on larger batches. - sync_devices and sync_driver_audit fetch jimi.track.device.detail concurrently via ThreadPoolExecutor(max_workers=8), cutting the daily registry sync from ~24s to ~3s for an 80-device fleet. - poll_track_list split into two phases: parallel API fetch (4 workers, no DB connection held) then one batched write. Previously the DB connection was held across every per-IMEI HTTP call, risking pool starvation. Security - _validate_token uses hmac.compare_digest for constant-time token comparison (closes timing side-channel). - _parse_data_list caps incoming items at WEBHOOK_MAX_ITEMS (default 5000) so a pathological push cannot blow memory. Tests - Fix test_null_alarm_type_skipped: its INSERT-count assertion was catching the ingestion_log insert written by log_ingestion. Filter that out so the test checks only data-table inserts. - Full suite: 66 passed. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
|
||
RESPONSIBILITY: Receives real-time push data from Jimi Tracksolid Pro servers.
|
||
|
||
Jimi's Data Push API POSTs telemetry to these endpoints as it arrives from
|
||
devices, providing real-time ingestion without polling. This is the ONLY way
|
||
to receive OBD diagnostics and DTC fault codes — those data types have no
|
||
polling endpoint.
|
||
|
||
ENDPOINTS:
|
||
/pushobd — OBD CAN bus diagnostics (Priority 1)
|
||
/pushfaultinfo — DTC fault codes (Priority 1)
|
||
/pushalarm — Alarm events (Priority 2)
|
||
/pushgps — GPS positions (Priority 2)
|
||
/pushhb — Device heartbeats (Priority 2)
|
||
/pushtripreport — Trip reports (Priority 2)
|
||
/pushevent — Device LOGIN/LOGOUT events (Priority 3)
|
||
/health — Healthcheck for Docker/monitoring
|
||
|
||
REVISIONS (QA-Verified):
|
||
[BUG-01] OBD event_time: try unix_to_ts before clean_ts (handles epoch timestamps).
|
||
[BUG-02] push_alarm: guard also checks alarm_type is not null (prevents FK violation).
|
||
[BUG-03] push_trip_report: _parse_trip_ts handles Jimi BCD format YYMMDDHHmmss.
|
||
[BUG-04] SAVEPOINT per item in all DB-writing endpoints (one bad item won't abort batch).
|
||
[BUG-05] Added /pushevent endpoint → writes to tracksolid.device_events.
