Major Architecture Refactor

  • Implements multiple worker threads to process incoming messages simultaneously

New Feature: Sequence Tracker
New Sequence Tracking logic provides nuanced Sparkplug sequence number validation:

  • Handles the Sparkplug 255→0 wraparound correctly

  • Distinguishes between: good, duplicate, one-off gap (exactly 1 skipped), large forward gap (triggers rebirth), out-of-order/under

  • Per-device sequence tracking to handle multi-device interleaving without false rebirth requests

  • On node rebirth, all per-device sequence entries for that node are cleared

  • 10-second rate limiter on rebirth requests to the same node to prevent rebirth spam

New Feature: Diagnostics Manager
A new $Diagnostics OPC device is exposed with real-time operational metrics:

  • Queue metrics: Queues.IncomingMessages, Queues.DistributionMessages, Queues.PendingDAUpdates, Queues.ProcessingDAUpdates, Queues.PendingVectorQueue,


     Queues.TotalWorkerQueue, Queues.Worker{N} per worker thread

  • Count metrics: Counts.TotalNodes, Counts.TotalDevices, Counts.TotalTags, Counts.ClientCount

  • Broker metrics: Brokers.ConnectedCount, Brokers.TotalCount, Brokers.Broker{N}.Online, Brokers.Broker{N}.IP

  • Performance: Performance.UptimeSeconds

New Feature: Internal OPC Items

  • ClientsConnected "” per-node diagnostic item

  • LastBirthTimestamp "” per-node and per-device, set on each birth/rebirth

  • LicenseStatus "” license validity now managed by MessageDistributor with expiration time

Performance Improvements

  • Sparkplug payload decoding moved out of the processor thread into a dedicated thread, unblocking message ingestion

  • Data message processing uses a concurrent queue with vector merging on a separate thread to reduce contention

Bug Fixes

  • Corrects a null pointer crash when cleaning up old OPC items during device death

  • Corrects state message construction and state monitoring

  • Adds an existence check before writing to an OPC item to prevent writing to deleted tags

  • Corrects handling of string metric writes

  • Corrects a comparison bug where the settings enum was compared directly to mosquitto's MQTT_PROTOCOL_V5 constant

  • Corrects an edge case causing broker connection to not recover after loss

  • Corrects out-of-bounds access in rebirth request handling

  • Corrects an issue where backfill files not being created

  • Duplicate MQTT messages are now silently ignored instead of processed

  • Adds guards for internal items to prevent errors during death message handling

  • Corrects handling of metrics where the datatype changes between birth messages

  • Corrects license validity check logic

  • Restores deletion of device tags on device death/shutdown

Logging Improvements

  • All log messages in BrokerConnection are rewritten with structured fields (host, port, error code, error string) for easier diagnosis

  • Corrects a crash/issue with empty logging directory

  • Corrects log message line endings

  • Separate log file for write operations vs. broker status

  • Removed per-line logging spam in ProcessBackfill

  • Adds logging for write message lifecycle
