DisposeRuntimes() now disposes and clears _rmwLocks, _creationLocks, and
_runtimeLocks so ReinitializeAsync/ShutdownAsync cycles don't orphan their
SemaphoreSlim instances. Mirrors the TwinCAT _bitRmwLocks fix already shipped.
Adds `Bit_write_surfaces_device_rejection_status` to AbLegacyBitRmwTests,
verifying that a non-zero libplctag status returned by the parent-word write
in WriteBitInWordAsync propagates as a non-Good OPC UA StatusCode rather than
being silently swallowed. Added a minimal `WriteStatusOverride` hook to
FakeAbLegacyTag (test-project-only) so the read half of the RMW still
returns 0/Good while the write half returns the seeded error code.
M1: add missing (object) cast to UInt64 arm of DecodeScalarBlock switch expression,
matching the Int64 arm style and the comment that each arm is boxed explicitly.
M2: short-circuit Timer/Counter writes in WriteAsync to BadNotWritable before
WriteOneAsync, so transient equipment-tag refs (Writable=true from parser) return
the same status code as authored tags rejected at init — documented in the docs.
Adds 6 pure unit tests pinning the area-detection precondition the guard relies on.
EncodeScalarBlock Timer/Counter throws remain as the defensive backstop.
- DecodeRegisterArray: add String and BitInRegister cases replacing the
default:throw; each element decoded by reusing DecodeRegister on its
contiguous register slice → string[] / bool[]
- ModbusEquipmentTagParser.TryParse: read optional arrayLength key from
TagConfig JSON and thread it into ModbusTagDefinition.ArrayCount
(null when absent or zero, preserving scalar behaviour)
- ModbusArrayTests: 8 new tests covering the two decode cases and the
equipment-tag parser/resolver path; 285/285 green
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).
