Code-review nits: SetFullName now throws on a blank reference (was silently
persisting FullName:null → silent deploy-time bind failure), and a new test
covers the alarm-typed re-pick combo (SeedDefaultAlarm over an already-edited
alarm leaves it intact).
After inline "New script" creates an SC-… id, the entry is now added
to _scripts BEFORE _form.ScriptId is set so the <InputSelect> has a
matching <option> on first render and the displayed label is correct.
Extracts VirtualTagModalHelpers.ResolveScriptLabel as a testable pure
helper (5 new unit tests in VirtualTagScriptDropdownTests).
Closes the code-review gap: the Enable/Disable success tests now assert the
derived '.Condition' object node (the CallMethodObjectIds capture was added
but unused), and a new test proves an already-suffixed condition node isn't
double-suffixed (mirrors AcknowledgeAlarmAsync_LeavesConditionSuffixAlone).
Closes the code-review coverage gap: AcknowledgeAsync now has its own
swap-across-the-gate regression test (CallAsync lands on the post-gate
session), the subscribe-path coverage gap is documented, and the bounded
fallback drops from 2s to 250ms (the buggy-path signal is a synchronous
pre-await read, so it always wins well inside the bound).
The OPC UA address-space build pipeline was named after a v2-roadmap
milestone number rather than its domain. Rename the family to describe
what it does (build/diff/apply the OPC UA address space):
Phase7Composer -> AddressSpaceComposer
Phase7CompositionResult -> AddressSpaceComposition
Phase7Planner -> AddressSpacePlanner
Phase7Plan -> AddressSpacePlan
Phase7Applier -> AddressSpaceApplier
Phase7ApplyOutcome -> AddressSpaceApplyOutcome
The 9 Phase7*Tests suites follow suit; Phase7ScriptingEntitiesTests ->
ScriptingEntitiesTests (it tests the scripting migration, not the
pipeline). Log-message prefixes move to the new class names.
Pure mechanical rename, no behavioral change. EF migration classes/IDs
(AddPhase7ScriptingTables, ExtendComputeGenerationDiffWithPhase7) are
immutable and left untouched, as are historical design docs.
Build clean; OpcUaServer 261/261, Runtime 272/272, ScriptingEntities
12/12 green.
Closes backlog #12: Galaxy's AckMsg attribute is WRITE-ONLY and the OPC UA
event SelectClause carries no comment field, making OperatorComment
unrecoverable on the sub-attribute fallback path. Documents the two concrete
reasons in-code and tightens the AlarmEventArgs XML doc; adds pinning test
OnAlarmEvent_GalaxyFallback_LeavesOperatorCommentNull.
Add AbCipEmulateNestedUdtTests (skip-gated, AB_SERVER_PROFILE=emulate) to close
the live-gate gap for nested-struct UDT discovery via CIP Template Object (class 0x6C)
threaded by commits 3d8ce4e8/d203f31c. Compiles + skips cleanly against ab_server
(no CIP Template Object service). Update docs/drivers/AbCip.md nested-struct section
to record the shipped decode path, the Emulate-only live-gate, and offline unit coverage.
Code-review I2: CoerceDateTime's missing-field sentinel was DateTime.MinValue
(Kind=Unspecified) — a downstream .ToUniversalTime() could shift it; now UTC-kinded.
M4: assert BrowsePath namespace==0 + the sentinel's UTC Kind.
Subscribe a real tag, register its gateway item handle, write via the
registry-wired writer: asserts the borrowed-handle write commits Good with
AddItemCallCount==0 (control with no source: ==1). Proves the subscription
handle is usable for a committing no-login supervisory write. Skip-gated on
MXGW_ENDPOINT + GALAXY_MXGW_API_KEY; verified live vs 10.100.0.48:5120 (3/3).
Make SubscriptionRegistry.TryResolveItemHandle confirm a live subscription
genuinely binds fullRef->handle (via the reverse index) rather than trusting
the forward-map hint + a bare liveness check. Fixes the cross-ref-same-handle
hazard (wrong-tag borrow) while preserving the legitimate
multiple-subscriptions-per-tag borrow. Adds cross-ref + same-ref-multi-sub
tests; drops a duplicate SubscriptionEntry <summary>; documents the writer's
supervisory-advise reconnect lifecycle.
GatewayGalaxyDataWriter now accepts an optional subscribedHandleSource
delegate; TryResolveCachedOrBorrowed checks _itemHandles first then the
source, so the first write to an already-subscribed tag skips the
AddItem round-trip. Borrowed handles are not cached (subscription
registry owns lifecycle). AddItemCallCount seam confirms gateway calls.
Add _itemHandleByFullRef (OrdinalIgnoreCase ConcurrentDictionary) maintained
in lock-step with _subscribersByItemHandle across Register/Remove/Rebind.
TryResolveItemHandle cross-checks the authoritative reverse map so a stale
forward entry can never hand out a dead handle. Also wires the scaffolded
_addItemCallCount increment in EnsureItemHandleAsync (field was declared but
never assigned, causing a TreatWarningsAsErrors build failure on the branch).
8 new xUnit + Shouldly facts covering register/case-insensitive/remove/rebind/
failed-handle/liveness-guard paths.
- ITwinCATClient.BrowseSymbolsAsync XML doc updated: states the implementation now
expands struct/UDT/FB symbols into atomic member leaves via TwinCATSymbolExpander;
callers receive only atomic/array leaves with full InstancePaths, never struct containers.
- AdsSymbolNode: cache IsStruct, Mapped, Children, ReadOnly as readonly fields computed
once in the ctor so repeated property access during recursive expansion doesn't
re-materialize or re-invoke MapSymbolType/IsSymbolWritable.
- BrowseSymbolsAsync: add operator-gated live risk note next to SymbolsLoadMode.Flat
warning that a real TC3 target may not populate SubSymbols in Flat mode, with
guidance to switch to VirtualTree if members don't surface — do not change mode now.
- TwinCATSymbolExpanderTests: simplify confusing `new string('.', 0)` no-op to `""`.
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.
