Use PostgreSQL leases and fencing for distributed ownership, require a durable SQLite outbox before RabbitMQ publication, and make Data Center ingestion transactional and idempotent.
BREAKING CHANGE: drivers require mandatory durable outbox configuration and use lease-aware ownership and telemetry contracts.
28 driver application.yml add dc3.driver.buffer; Dockerfile each stage adds dc3/data dir and VOLUME; docker-compose main/dev add driver_data named volume
Fix @since 2026.6.2 -> @since 2026.5.22 on 40 files across 17 protocol
drivers (serial, dlms, fins, mysql, ethernet-ip, zigbee, bacnet-ip,
snmp, ble, can, oracle, postgresql, iec104, lwm2m, tcp-udp, http,
sqlserver). The @since value was later than @version 2026.5.22, which
is impossible — a class cannot exist in 5.22 yet be introduced in 6.2.
Document 31 modules that had no README: dc3-center-agentic, dc3-e2e,
common modules (agentic, sql, test, resource-registrar) and the facade
subsystem (api/grpc/local-auth/local-data/local-manager), plus 21
drivers. Content is grounded in each module's pom/yaml/source; WIP
skeleton drivers (can, dlms, ethernet-ip, iec104, lwm2m, zigbee) are
flagged as such.
Part of the x-dc3-ai annotation-standard rollout. Complete method/param javadoc (TokenService, RepositoryService, RuleEngine, ...), flag work-in-progress utilities and drivers (X509Util, MQTT/CAN/DLMS/... ) with explicit WARNING notes, and remove redundant inline comments / blank lines from query/VO/ext/constant classes plus mapper indentation. Comment/doc only, no behavior change.
- Update test references to the renamed *TypeEnum/RuleStatusEnum.
- Add the new builder/PermissionProvider constructor args to the affected
service-impl test setups.
- Fix pre-existing failures unrelated to this work: String-vs-Long assertions
(DriverStatusServiceImplTest), save->saveBatch (EntityStateExpiryScannerTest),
List.of(null) NPE (AlarmRulePipelineServiceImplTest), and the cache/batch
refactor expectations (PointValueServiceImplTest).
Remove unused imports, dead constructors, redundant fields, and unreferenced
local variables across 16 protocol driver implementations and supporting
classes. Add type-specific Encodable creation for BACnet write operations.
Remove DEFAULT_KEY and DEFAULT_PASSWORD constants from AlgorithmConstant.
Require DC3_SECURITY_KEY env var at startup — fail with IllegalStateException
if not configured instead of silently falling back to a well-known string.
Remove hardcoded default HMAC secret from HmacAuthProperties. Log a warning
when request signing is disabled in WebFilterConfig.
Require DC3_SECURITY_DEFAULT_PASSWORD for password reset operations instead
of falling back to the hardcoded 'dc3dc3dc3'.
Replace all YAML password fallback values (dc3dc3dc3) with empty defaults so
misconfigured deployments fail at connection time with a clear error rather
than silently connecting with a well-known password.
