Extends RecordingSink to capture isArray/arrayLength per EnsureVariable call,
adds two applier-level tests asserting the wire-through for array and scalar
plans, adds float/overflow InlineData rows to ExtractTagArray theory, and
corrects the ExtractTagArray XML-doc wording (null => unbounded ArrayDimensions=[0]).
Two bugs caught by live verification against the mxaccessgw at 10.100.0.48:5120:
- MaxAttempts=1 produced an invalid Polly RetryStrategyOptions -> the probe failed
on every real gateway. Removed the Retry override (matches GalaxyDriver); fail-fast
is already guaranteed by the TCP preflight + the per-call deadline.
- A rejected key surfaces as a typed MxGatewayAuthenticationException, not a raw
RpcException, so 'auth-rejection = reachable' was bypassed. Catch the typed auth/
authorization exceptions -> Ok=true.
Adds DriverProbeHandshakeE2eTests: direct-probe, skip-gated cross-protocol green/red
discrimination (Modbus, OpcUaClient, Galaxy + a local real OPC UA server).
HandleRestartDriver stopped + respawned the child within one synchronous
message handler, reusing the base actor name drv-<id>. Context.Stop is async
(the child processes its own stop on its own mailbox), so the old child was
ALWAYS still registered when the respawn ran — Context.ActorOf threw
InvalidActorNameException deterministically on every AdminUI Restart press,
crashing + restarting the host.
Fix: a monotonic _childSpawnGeneration counter (single-threaded actor) feeds a
-g<gen> suffix on every spawned child name, so a respawn can never collide with
the still-terminating predecessor. Children are tracked by the _children dict
(by IActorRef), never by actor path, so the suffix is invisible to callers.
This also closes the same-shaped latent race in the reconcile path (a removed-
then-readded instance, and a driver-type-change ToStop+ToSpawn in one plan).
Regression test RestartDriver_respawns_the_child_without_an_actor_name_collision
(verified: FAILS on the old code with the exact InvalidActorNameException,
PASSES with the fix). Runtime.Tests 238/238 green. Code-reviewed (approved).
C1 (critical): a boundary tie cluster larger than NumValuesPerNode could
silently truncate a resumed read to GoodNoData, permanently dropping the
un-emitted ties — the (timestamp, skip) cursor cannot advance past a single
timestamp the fixed-(start,end,cap) backend keeps re-returning. Now detected
and failed LOUDLY per node with BadHistoryOperationUnsupported + a log naming
the tag/timestamp/cap; documented in Historian.md with the larger-cap remedy.
Regression test Raw_tie_cluster_larger_than_page_fails_loudly_not_silently.
I3: build HistoryData before Save() so a projection failure can never orphan a
stored continuation cursor.
N1 (YAGNI): drop the never-produced HistoryReadKind enum + Processed-only
Aggregate/IntervalTicks fields from HistoryContinuationState — only Raw pages.
N3: ComputeResumeCursor guards its documented non-empty precondition.
I1: document InMemoryHistoryContinuationStore's eventual-consistency (test double).
Build clean, 182/182 OpcUaServer tests pass.
