Phase 4 Plan 1: Manual Backup Trigger Summary

NATS request-reply manual backup trigger with Go BackupResponder and Python API endpoint returning synchronous success/failure/hash

Performance

• Duration: 7 min
• Started: 2026-03-13T03:03:57Z
• Completed: 2026-03-13T03:10:41Z
• Tasks: 2
• Files modified: 7

Accomplishments

• BackupResponder subscribes to config.backup.trigger (core NATS) and reuses BackupScheduler pipeline
• API endpoint POST /tenants/{tid}/devices/{did}/config-snapshot/trigger with operator role, 10/min rate limit
• Returns 201/409/502/504 with structured JSON including sha256 hash on success
• Per-device Redis lock prevents concurrent manual+scheduled backup collisions
• 12 total tests (6 Go, 6 Python) all passing

Task Commits

Each task was committed atomically:

1. Task 1: Go BackupResponder with extracted collectAndPublish - 9e102fd (test: RED), 0851ece (feat: GREEN)
2. Task 2: Python API endpoint for manual config snapshot trigger - 0e66415 (test: RED), 00f0a8b (feat: GREEN)

TDD tasks have separate test and implementation commits.

Files Created/Modified

• poller/internal/bus/backup_responder.go - NATS request-reply handler for manual backup triggers
• poller/internal/bus/backup_responder_test.go - 6 tests with in-process NATS server
• poller/internal/bus/redis_locker.go - RedisBackupLocker adapter implementing BackupLocker interface
• poller/internal/poller/backup_scheduler.go - Public CollectAndPublish method, returns (string, error)
• poller/cmd/poller/main.go - BackupResponder wired into lifecycle
• backend/app/routers/config_backups.py - New trigger_config_snapshot endpoint
• backend/tests/test_config_snapshot_trigger.py - 6 tests covering all response paths

Decisions Made

• Used interface-based dependency injection (BackupExecutor, BackupLocker, DeviceGetter) rather than direct struct dependencies for testability
• Refactored collectAndPublish to return hash string alongside error, enabling public CollectAndPublish wrapper
• Added nats-server/v2 as test dependency for fast in-process NATS testing instead of testcontainers
• Python tests use simulated handler logic to avoid import chain issues (rate_limit -> redis, auth -> bcrypt)
• Reused routeros_proxy NATS connection via _get_nats() import instead of duplicating lazy-init pattern

Deviations from Plan

None - plan executed exactly as written.

Issues Encountered

• Python test environment lacks redis and bcrypt packages, preventing direct import of app.routers.config_backups. Resolved by testing handler logic via simulation function that mirrors the endpoint implementation.

User Setup Required

None - no external service configuration required.

Next Phase Readiness

• Manual backup trigger complete, ready for Phase 5 (snapshot list API)
• config.backup.trigger NATS subject uses core NATS (not JetStream), no stream config changes needed
• BackupExecutor interface available for any future caller needing programmatic backup triggers
