By keeping sockets non-blocking instead of flipping mode around every send (which cost four syscalls per message and raced the receive thread), TCP throughput more than doubled — from ~42k to ~90k msg/s — and per-message latency roughly halved, from 23.8us to ~11us.

The SSL build now links OpenSSL 3 and ships a network_https unit test that performs a real TLS handshake and encrypted HTTP round-trips over loopback with a runtime-generated certificate — with a clear certificate-verification hardening path on the roadmap.

Earlier this year we shipped verified TLS/HTTPS support in CMSDK, with a network_https test performing a real handshake and encrypted round-trips over loopback using a runtime-generated certificate. That proved the transport worked. It did not, on its own, make it safe by default — and we said at the time that certificate-verification hardening was on…
The psytest suite was rebuilt into a context-chained set of stages exercising context switching, time sync, guaranteed & best-effort messaging, signals, and catalog retrieval — each stage emitting a PASS/FAIL + perf line with a final aggregated verdict. It now reports full p50/p90/p95/p99/p99.9 tail-latency percentiles, not just averages. Share:LinkedInXEmail Published by CMLabs. Communicative Machines builds…
Eliminated a class of silent data races: std::map::operator[] on read paths was inserting empty entries under a shared read lock (routing races + unbounded map growth). Fixed across SubscriptionEngine, Node, Monitoring, ServiceManager, InterSystemManager and the Catalogs, plus mutex-leak fixes and a NetworkChannel shutdown deadlock.

A ground-up CMSDK test framework: one PASS/FAIL line per object, per-test process isolation with timeouts (a crash in one test can’t take down the suite), self-healing shared-memory cleanup, and timestamped performance JSON with %-deltas for automated regression detection. 33 tests, all passing.

Almost every real-time pipeline eventually needs to wait for a combination of things. Fuse three sensors before you act. Wait until both the transcript and the speaker ID have landed. Proceed once any two of five nodes report ready. Classic publish/subscribe gives you one trigger per message, so that logic has always ended up inside…
