User decision: save, Test Connect, live browse and the deploy gate keep
refusing out-of-namespace credential references, but an ALREADY-DEPLOYED
driver must not fault at the upgrade restart or (Galaxy) at the next
gateway reconnect, since ReopenAsync re-resolves Gateway.ApiKeySecretRef.
- LegacyCredentialReferenceTracker (Core.Abstractions): the one, deprecated,
call-site-chosen compatibility path. Running Galaxy (InitializeAsync,
ReopenAsync, ack fallback) and OpcUaClient (session open) pass it and keep
the pre-#815 semantics (case-insensitive prefixes, Galaxy file:, OpcUaClient
literal pass-through) with a rate-limited Warning (driver/field/allowed
form, never the value) and a credential-compat:<field> diagnostics entry
(both drivers now implement IDriverDiagnostics). Browsers and probes pass
none and stay hard-fail; Heidenhain has none.
- Deploy-gate message names the migration.
- Upgrade preflight: CredentialReferencePreflightService (admin nodes, once
after ApplicationStarted, ConfigDb only, resolves nothing) logs a Warning
per Draft row / Deployed-artifact finding; the /raw banner shows them plus
Running drivers reporting warn-only use (driver-health diagnostics).
- docs/security.md: exact replacement table (incl. the old form default
env:MX_API_KEY, file:, un-namespaced secret:, casing changes), the
ReopenAsync reconnect behaviour, the warn-only window and its removal.

Comms_loss_invalidates_every_remote_value_and_recovery_republishes_identical_values failed
1/40 on base 5bbe1e3c (and 1/29 on this branch): "Capabilities/Identity should be
CommunicationLost but was Supported". RetireAll -> Invalidate publishes every tag in authored
order under one lock, capability LAST, and the recorder sees each publish as it happens; the
test asserted the capability the instant the five value tags read BadNoCommunication, i.e.
before the pass's final publish. Now the wait includes the capability's CommunicationLost
(a presence the pass must produce) and additionally asserts no value went Good again during
the outage.
Second latent race fixed in the same test: Degraded holds through Backoff AND Connecting, but
the host status is Stopped only in Backoff (Unknown while a reconnect attempt is in flight),
so the test now waits for Degraded && Stopped instead of sampling whichever phase it hit.
After the fix: 79/80 filtered runs passed and 10/10 full-suite runs; the one non-pass was a vstest
"failed to connect to testhost after 90 s" host-startup timeout (the test never ran), not a test result.
SDK 2.0.1 checks the server host name in TWO places: Session.OpenAsync (after
the chain is trusted) and DefaultSessionFactory.CreateChannelAsync, against the
certificate in the GetEndpoints reply and before any security-mode test. opc-plc
sends a certificate on its None endpoint, so `connect -u
opc.tcp://10.100.0.35:50000 --validate-host-name` was refused on an
unauthenticated channel, where a host check proves nothing.
All three call sites now pass checkDomain only when the selected endpoint's
SecurityMode != None: OpcUaEndpointSelection.CheckDomainFor for the driver
(OpenSessionOnEndpointAsync, so the failover sweep too) and the AdminUI browser;
the same expression in Client.Shared ConnectToEndpointAsync (shared by
failover). New live tests: driver None + flag on vs :50000 reads; browser None +
flag on vs the NAT fixture browses; the secure + flag refusals still hold.
Docs: name both check sites; a zone-qualified IPv6 host never matches (FindDomain
compares the zone too), so link-local needs validateServerHostName=false; the
match is loose (first label alone, subject DC= parts count, no wildcards), which
caveats the CA recommendation.
- RawTagRowRules: the ONE driver-dispatched authority on Tag-ROW rules (access level /
Tag.DataType). RawTreeService's save path, the CSV import's staged review grid
(RawTagCsvMapper) and the manual-entry grid all call it; no call site names a driver.
A ReadWrite or mistyped Heidenhain row is now invalid IN THE PREVIEW instead of only at Commit.
- Manual-entry grid + tag modal: when the driver dictates the data type for the row's
address (RawTagRowDefaults.DictatedDataType), the field is a locked read-only value instead
of a select that commit silently replaced; the grid runs the row rule client-side and no
longer rewrites the row at commit.
- Driver/device modals: the credential refusal is shown once (the modal's save-gate notice);
HeidenhainDriverFormModel / HeidenhainDeviceModel.Validate report only ranges / endpoint.
- docs/drivers/Heidenhain.md: #831 alarm conditions + rediscovery, #830 authoring behaviour.
Tests: HeidenhainAuthoringUxTests (CSV preview == ImportTagsAsync row-for-row, dictated type
is what the save path accepts, single credential surface, ALARM: seeding, CSV alarm rows,
AlarmMs round-trip); HeidenhainAuthoringTests updated for the single-notice rule.
- ALARM: selectors (HeidenhainAlarmSelector, Contracts): ALARM:*, ALARM:OTHER,
ALARM:CLASS=<r>[/GROUP=<r>][/NUMBER=<r>] (<r> = n | lo..hi; negative numbers allowed).
An ALARM: address and the cross-driver alarm object only work together — the factory
refuses either alone, so editor, save path, CSV and deploy inspector agree. Data type
fixed Boolean; never a value (ReadAsync BadNotSupported), never in a data subscription.
- HeidenhainDriver implements IAlarmSource: one condition per ALARM: tag at its RawPath,
driven by the SAME allowlisted R_RI 27/28 walk on the control's single loop, on the new
Polling.AlarmMs cadence (default 2000 ms, only for controls carrying an ALARM: tag).
FOCAS #647 transition rules (Raise / Retrigger / Clear), identity = class+group+number+text,
deterministic display order, told-record on the driver instance, recorded only while a
handler listens. A failed walk (refusal, overflow, comms loss) is quality-only, never a clear.
- Acknowledge is LOCAL-ONLY: AcknowledgeAsync is a no-op success (FOCAS/MTConnect posture);
Lsv2ReadOnlyPolicy is unchanged — no ack or write request exists.
- Opt-in per tag, no driver flag (FOCAS #647 / MTConnect #626 precedent); Alarms/* arrays unchanged.
- IRediscoverable: a reconnect whose R_VR identity (model / NC / PLC / options) differs from
the previous session raises OnRediscoveryNeeded once (advisory re-browse chip). No extra traffic.
- AdminUI: Heidenhain joins NativeAlarmModel's alarm drivers; the typed editor fixes ALARM:
tags at Boolean and seeds/drops the alarm object with the selector; driver form gains
"Alarm conditions (ms)". (HeidenhainDriverFormModel also carries the #830 credential-notice change.)
Tests: HeidenhainAlarmTests (grammar, pairing, rules, simulator e2e with the captured iTNC 530
alarm record, local-only ack = zero bytes sent, quality-only outage/refusal, rediscovery),
Runtime.Tests HeidenhainNativeAlarmEndToEndTests (real DriverHostActor condition), a
DraftValidator case, and the NativeAlarmDriverSetGuard now scans the Heidenhain driver.
#816 finding: the SDK checks that the server certificate names the host only
when a session is created with checkDomain:true. The driver, the AdminUI
browser and Client.Shared all called the 8-argument
DefaultSessionFactory.CreateAsync, which forwards checkDomain:false — so no
host-name check ever ran (why a trusted NAT cert for *.invalid browsed fine
over an IP in #813). When enabled the SDK (Session.OpenAsync ->
ValidateDomains -> FindDomain) compares ConfiguredEndpoint.EndpointUrl.IdnHost
— the CONFIGURED host, because OpcUaEndpointSelection/EndpointSelector
rewrote the advertised one — against the cert's DNS/IP SANs; secured
sessions only, and the auto-accept handler accepts a mismatch.
Policy: certificateValidation.validateServerHostName, tri-state. Unset =
OpcUaCertificateValidationOptions.DefaultValidateServerHostName = false, the
pre-#816 behaviour, so nothing changes on upgrade; true = validate the
configured host; false = explicit NAT/port-publish opt-out. Threaded into the
driver, the AdminUI browser (same JSON) and the AdminUI form (a select that
keeps "unset" unset), Client.Shared ConnectionSettings.ValidateServerHostName
and the CLI --validate-host-name. A driver refusal names the opt-out.
#818: the NAT fixture's /app/pki is on the opc-plc-nat-pki volume (verified:
same thumbprint across --force-recreate), its PUBLIC cert is committed as
Docker/nat/opc-plc-nat-server.der, and NatPublishedEndpointBrowseTests run
every secure browse on a throwaway PKI (internal browser seam): refusal with
nothing trusted, positive with the cert trusted (unset/false host check), and
a BadCertificateHostNameInvalid refusal with the check on. The trusted cert is
OPCUA_NAT_SERVER_CERT or the committed one (skip on thumbprint mismatch);
OPCUA_NAT_SERVER_CERT_TRUSTED is retired. CI exports its throwaway NAT
container's public cert. ServerHostNameValidationTests pin the driver against
the plain opc-plc. MIN_EXECUTED not raised (needs a hosted run): +6 in
v2-integration (440 -> 446), documented in scripts/ci/README.md.
The opc-plc image ships no netstat, so the old check left otopcua-opc-plc
permanently unhealthy. Same probe as the NAT fixture (27302314). Redeployed
to /opt/otopcua-opcuaclient on the shared docker host; reports healthy.
.NET's Uri parses a zone ([fe80::1%eth0]) but drops it from Host, Authority,
AbsoluteUri and ToString(); only DnsSafeHost/IdnHost carry it. The shared
OpcUaEndpointUrlRewriter rebuilt the URL through UriBuilder, so the zone was
lost and link-local endpoints were unroutable. The SDK dials
new Uri(EndpointUrl).IdnHost (TcpByteTransport -> DnsEndPoint), which keeps
it, so splicing the zone back into the string is enough. Kept verbatim
(%eth0, %4, or RFC 6874 %25eth0) so the session dials exactly what
GetEndpoints reached. Applies to the driver, the AdminUI browser and the
Client CLI/UI (all share the rewriter).
#822: HISTORIAN_SQL_TEST_CONNECTION example now targets the shared host
10.100.0.35,14330 with its committed dev sa password (OtOpcUaDev_2026!); the
docker-dev rig's own localhost,14330 password (OtOpcUa!Dev123) is called out as
a different instance. New labelled (project: lmxopcua) QuestDB fixture stack
tests/.../Historian.QuestDb.IntegrationTests/Docker/docker-compose.yml
(questdb/questdb:10.0.1, PG wire :8812, console :19000), deployed to
/opt/otopcua-questdb on the Docker host; documented in infra/README.md §2a,
docs/Historian.md, CLAUDE.md endpoints and the historian rules.
Also corrects infra/README's stale "only MQTT/NAT carry the label" note.
Docs for #820 (nineteen served aggregates, DurationGood/DurationBad in ms,
Gateway still refuses) and the #821 facts (Part 13 vs frozen live vs stock
SDK 2.0.1, both directions; decision open with #809).

A Designer could point a Galaxy / OpcUaClient endpoint at a host they control,
set a credential field to any reference the node can resolve
(env:ConnectionStrings__ConfigDb, env:ServerHistorian__ApiKey, secret:<any>,
Galaxy file:<any path>) and click Test Connect / live browse; the node resolved
the value and sent it to that host.
One shared rule in Core.Abstractions (CredentialReferences +
DriverCredentialPolicy) generalises the #803 Heidenhain namespace:
- Galaxy: secret:galaxy/... | secret:otopcua/galaxy/... | env:OTOPCUA_GALAXY_... |
legacy env:GALAXY_MXGW_...; file: refused; dev:/literal API key unchanged.
- OpcUaClient: secret:opcuaclient/... | env:OTOPCUA_OPCUACLIENT_...; literals unchanged.
- Heidenhain adopts the shared parser/resolver (namespace unchanged).
Enforced at the AdminUI save path (DriverConfigSaveGate), the deploy gate
(CredentialReferenceDeployChecks, code CredentialReferenceOutOfScope), Test
Connect (AdminOperationsActor, before any probe), live browse
(BrowserSessionService, before any browser) and again at resolve time in every
driver/browser (fail closed, before any store/env read).

#820: SqlServer + QuestDB now serve Part 13 DurationGood / DurationBad from the
same Good / Bad region totals TimeWeightedAggregator already computes for
PercentGood / PercentBad — reported in milliseconds (OPC UA Duration, the SDK's
unit), Uncertain time in neither (Mantis 0006166), same BadNoData / status /
Partial rules. AggregateFamilies.Served grows 17 -> 19, so i=11201 and the
up-front refusal follow automatically; Gateway still refuses both (explicit
served set, unchanged). Client.Shared AggregateType / mapper / CLI gain both.
The #796 oracle answers DurationGood through the Good-only subclass as well.
QualityMix conformance asserts both directly (Q and QP, hand values, ms, and
= PercentGood x interval), replaces the "refused up front" test, and adds
Duration* to the forward/reverse/truncated oracle comparisons.
#821 (facts only, no decision): SdkAggregateParityTests pins an Uncertain-first
late-start interval (QP over [0,20), both directions) against ours (Part 13
Total 163.96, TimeAverage 10.93), the frozen 1.5.378.182 calculators (188.96,
9.448), SDK 2.0.1's stock calculators (188.96, 9.448) and a Good-first control
(all 163.96); LiveAggregateLateStartFactsTests pins the same through the booted
server's runtime AggregateManager (live AggregateFilter) incl. DurationGood
15000 / PercentGood 75 there vs 8000 / 40 in HistoryRead (#809). QualityMix
adds the reverse late-start variant (reverse TW pin + reverse oracle windows).

The Test-Connect probe set is resolved inside the AdminOperations Akka starter; resolving
ISecretResolver there walks AddZbSecrets -> IAuditWriter -> ActorAuditWriter, whose ctor needs
AuditWriterActorKey (registered later in the same builder). Found by the docker-dev live gate.
Regression test: resolving the probe set never resolves ISecretResolver (fails before the fix).
Also: TagRowProblem doc comment re-attached; Heidenhain credential help text names the
secret:heidenhain/ and env:OTOPCUA_HEIDENHAIN_ namespaces.
- Review 1: RawTreeService Create/UpdateDriver and Create/UpdateDevice refuse a Heidenhain
config whose password fields are not blank / secret:heidenhain/... / env:OTOPCUA_HEIDENHAIN_...
(DriverConfigSaveGate over HeidenhainOptionsParser.DescribeCredentialProblems: top level,
Access, Devices[], case-insensitive keys; the value is never echoed), so a literal password
never reaches the draft DB. The driver and device modals show the reason and disable Save.
- Review 8: CreateTag/UpdateTag/ImportTags (tag modal, manual entry, CSV import, browse commit)
refuse a ReadWrite Heidenhain tag or a Tag.DataType that disagrees with what the driver
publishes (HeidenhainTagRules: catalog type, Float64 => Double, or the binding's dataType).
The tag modal and manual-entry grid fix the access level at Read and derive the data type from
the address (RawTagRowDefaults). New deploy gate HeidenhainTagDataTypeMismatch.
- docs/drivers/Heidenhain.md: credential namespace convention + why, the save-path and deploy
enforcement, optional-role credential behaviour, BadConfigurationError, backoff/ordering notes.
Tests: HeidenhainSavePathTests (service save path; red with the gates disabled) and new
DraftValidatorHeidenhainTests cases.
- Credential exfiltration (review 2): password references are scoped to
secret:heidenhain/<name> and env:OTOPCUA_HEIDENHAIN_<NAME> only. Enforced by
HeidenhainOptionsParser.TryParseCredentialReference (parser, probe, deploy gate) AND again at
resolve time in HeidenhainCredentials (fail closed without consulting the store or the
environment), so Test Connect can no longer send env:ConnectionStrings__ConfigDb or another
subsystem's secret to an arbitrary Host. The probe also refuses an unsendable password.
- Optional-role credentials (review 6): an unresolvable/NUL/non-Latin-1/>247-byte DNC or DATA
credential never sends a login and never fails the session; the reads needing that role are
BadConfigurationError (capability ConfigurationError) and INSPECT telemetry continues. A
policy refusal inside AcquireAsync is per-tag, not a session teardown.
- Start after DisposeAsync is a no-op (review 3); initial subscription push and Publish are
ordered under one lock (review 4); JSON-null sections are normalised and the acquisition loop
catches every fault (review 5); backoff resets only after a session published a poll batch,
with clamped delays (review 7).
Tests: HeidenhainReviewFixTests + namespace/normalisation tests in HeidenhainConfigTests;
each was confirmed red against the reverted fix.
Review of af5c9744:
1. UNS reference variables (s=Area/Line/Equip/Eff) of a moved or renamed
equipment stayed readable/writable under the OLD names' grants: they now
resolve as ReferenceVariable and are authorized at their split path only
while it equals their live equipment folder's placement (live chain ==
generation chain) + one name; otherwise denied (Read and Write).
2. TryPlaceScriptedCondition now also requires the owner folder's live chain
to match the generation (AuthorizeScriptedCondition gains ownerFolderChain),
so a moved equipment's alarm/children/commands follow its folder.
3. Identifiers containing NUL are denied before the decision cache, keeping
client ids disjoint from the NUL-prefixed resolved-scope keys (a client
could otherwise poison a real folder's cached verdict for its key shard).
4. An id no live node holds is Unknown: placed at [\0unknown] so only
Cluster / Namespace-uns grants decide it (a removed opaque id can no longer
split onto a same-named narrow grant; narrow grantees get no NodeDeleted for
removed UNS folders/vtags/conditions — documented); 4-segment
reference-shaped ids keep their split.
5. A wire test drives placements from DeploymentArtifact.ParseDataPlaneAuthority.
Baseline updates: #797 owner tests (unit + wire) and Sdk2RepeatedAlarmAuthority
now install folder scopes; Sdk2HistoryAuthority's UNS alias used the RAW path
as its UNS id (never minted in production) and now carries EqA/HistoryAlias.
Each new guard was falsified (reverting it fails its test).
Real Heidenhain driver (factory-built from a merged config) against the in-process LSV2
simulator inside DriverInstanceActor: subscribe publishes Good, an OPC write is refused by
the runtime (no IWritable) with nothing sent to the control, an outage stamps
BadNoCommunication, recovery re-publishes the identical value Good, and only allowlisted
telegrams ever reach the simulated control.
UNS Area/Line/Equipment folders are minted under their opaque entity ids
(s=UA-/UL-/EQ-...), virtual tags under s=EQ-.../Name and scripted conditions
(+ #629 children) under s=<ScriptedAlarmId>[/...], while every UNS grant is
planted at a NAME path. DataPlaneAuthorizer split those ids, so with
Security:Acl:Enabled a narrow (Area/Line/Equipment) grant could not Browse,
Read, subscribe or HistoryRead them, and Server-object delivery never reached
it — so a narrow key never held the EventId Ack/Confirm/AddComment need.
- The generation carries UnsFolderScopes (folderId -> path + id chain), built
by DeploymentArtifact from the same AclScopePathResolver as the grants; ids
two entity kinds share are dropped; plumbed through IDataPlaneAuthoritySink.
- OtOpcUaNodeManager.ResolveUnsAclSubject reports live facts (folder id
ancestry / scripted owner binding); attached by the Authorizer setter.
- Evaluate places the subject against the CURRENT generation before the
decision cache, which now caches the walk keyed on the resolved scope.
Folders require live chain == generation chain (a moved equipment is denied
under old and new line until the rebuild). Owned nodes (vtags, conditions,
children) get owner path + a reserved segment, so Tag grants and their
Browse transit never expose them. Conditions share TryPlaceScriptedCondition
with the #797 command gate.
- Server-object visibility of a scripted condition is decided on the
condition alone, so a moved alarm cannot reach its old owner there.
Tests: UnsFolderScopeWireTests (opaque ids, end-to-end browse -> EventId ->
Acknowledge on an Equipment grant; sibling denied; Tag-only grant; moved alarm
and moved equipment stale windows). Rig tests now install folder scopes
explicitly (ServerEventRig.FolderScopes); the #797 recreate test deliberately
asserts the moved alarm is invisible to the Cluster observer in the window.
- HeidenhainDeployChecks (wired into DraftValidator): HeidenhainTagWritable refuses a
ReadWrite access level on any Heidenhain tag, so no node is ever advertised writable;
HeidenhainCredentialPersisted refuses a literal password in DriverConfig/DeviceConfig
(only blank / secret: / env: references; the value is never echoed);
HeidenhainConfigInvalid for out-of-range settings or a tagged device without an endpoint.
- EquipmentTagConfigInspector maps Heidenhain to HeidenhainTagDefinitionFactory.Inspect.
- Driver validates only devices that carry tags (an unconfigured default Device1 no longer
faults the driver).
- Lift an Agent's MTConnectError body under a non-2xx status (cppagent 2.x serves
OUT_OF_RANGE as HTTP 400, NO_DEVICE as 404) into the refusal-marked
InvalidDataException, reading at most 64 KiB. The 400 used to be a transport
fault, so the OUT_OF_RANGE re-baseline never ran against a real 2.x Agent.
- Run the instanceId restart test on every re-baseline snapshot: on 2.x a restart
is first seen there (the old cursor gets a 400), and was adopted silently.
- Report the stream Degraded after 3 consecutive re-baselines with no /sample
chunk (it read Healthy for ever); LastSuccessfulRead keeps advancing.
- Prohibit DTDs on the /probe and write-answer parses; bound the streams walk to
64 levels (unbounded recursion = uncatchable StackOverflowException).
- Skip structural elements under <Components>/<Devices> instead of failing the probe.
- Never serve a non-finite float as Good; serve integer-valued decimals on
integral tags losslessly (a real fraction stays BadOutOfRange).
- Merge sibling browse containers that resolve to one folder name.
Unit 678 -> 714, integration 18 -> 20 (live fixture); every gap test failed first.
Native LSV2 TCP transport (default port 19000; no Java/Python/vendor SDK), ported from
the ignitionoee v0.20.3 reference driver:
- Lsv2ReadOnlyPolicy: payload-aware outbound allowlist (A_LG INSPECT/DNC/DATA, R_VR, R_PR,
R_RI 22-28/30-34/51, bounded R_MB, R_DP), applied in Lsv2Codec.Frame before any byte is
written; no public raw-command API.
- Lsv2Client: serialized transactions, one monotonic deadline per transaction, EOF/oversize/
unexpected/trickle close the client; Close never waits on the gate.
- Lsv2Data / HeidenhainBindingCodec: reference decoders, R_PR byte-capacity + element-index
rules, next-area cap, DATA Boolean 00/01/FF, strict non-truncating coercion.
- HeidenhainSession: per-batch wire cache, refusal suppression, provisional DNC denial retry,
alarm cursor (57 = end, overflow = BadOutOfRange), capability strings.
- HeidenhainDeviceRuntime: one loop per control, generation-guarded publication, all-node
BadNoCommunication on comms loss, bounded exponential reconnect.
- HeidenhainDriver: cached ReadAsync, push subscriptions deduped on (value,status), static
catalog discovery (no connect), host status, diagnostics, skipped-tag report. No IWritable.
- Probe (INSPECT login + version) and factory registered in DriverFactoryBootstrap (probe on
admin nodes too); DriverTypeNames.Heidenhain.
Tests: 159 unit tests against an in-process LSV2 simulator incl. the Java fixtures' captured
iTNC 530 replies as golden vectors; env-gated LiveIntegration category for real hardware.
QualityMixConformance (SqlServer + QuestDB): tag Q mixes Good/Uncertain/Bad
regions across eight 10 s intervals (two all-Uncertain - Mantis 0006166 0%/0% -
one through an Uncertain bound, plus Uncertain bounds from a sloped non-Good end
and from a hold into an outage); tag QP has data starting and ending inside
intervals. PercentGood/PercentBad are asserted against hand-derived Part 13
DurationGood/DurationBad, the oracle is checked against the same hand values,
and Count/Average/TimeAverage(2)/Total(2)/Start/End/Delta/Interpolative are
compared with the #796 oracle forward, reverse and truncated.
Teeth: with SdkAggregateOracle.Run answering PercentGood from the baseline
(Uncertain as Good), 8 tests fail per backend; all pass with the fixed oracle.
Records a new SDK divergence: with an Uncertain first sample the baseline
TimeAverage/Total integrate the pre-data span as a ramp from 0; ours covers
only the data (Part 13) - pinned by hand.
A wrong published value now reports its Success/Value/Reason/StatusCode, the
publish's wall time against the run budget, the run guard's in-flight /
refused / quarantined counters, thread-pool and GC state around the call,
the shadow stats, and the tails of the script and runner logs.
Reproduced under heavy load (32 `yes`, test at nice 20, load avg 300+):
3 of 8 runs failed, every one because the SIBLING's shadow run missed the
300 ms soft deadline in the starved worker ("shadow Failed [budget] script
timed out after 0.3s") and was rightly recorded as a sibling mismatch. No
published value was ever wrong. The out-of-process soft deadline is armed at
submit, so it covers the pipe round trip and worker scheduling too.
The run budget (which is also the worker's soft deadline) goes to the 2 s
production default; no assertion changes. The runaway still runs away and is
killed at T + HardGrace, so nothing the test proves depends on T being short.
Docker/nat/docker-compose.yml (stack /opt/otopcua-opcuaclient-nat on 10.100.0.35,
project: lmxopcua label): opc-plc 2.14.10 advertising --ph=otopcua-opc-plc-nat-private.invalid
on internal 50000, published on 50010, so every advertised URL is unreachable on host AND
port. Deployed; NatPublishedEndpointBrowseTests 3/3 against opc.tcp://10.100.0.35:50010
(and the secure case positive once, with the fixture cert temporarily trusted).
CI: integration-fixtures.sh starts a throwaway otopcua-ci-opcplc-nat (50110->50000) and
exports OPCUA_NAT_ENDPOINT; v2-e2e.yml points it at the shared stack. infra/README.md,
scripts/ci/README.md and the fixture README document it.
Client.Shared now project-references Driver.OpcUaClient.Contracts (Core.Abstractions
only, no NuGet/SDK; pinned by ContractsIsDependencyLightTests) and delegates the
host/port rewrite to OpcUaEndpointUrlRewriter, deleting its own copy.
The two copies differed; reconciled toward the client so its pinned behaviour is
unchanged (EndpointSelectorRewriteParityTests, written green against the old copy):
- no-op rewrite (same host case-insensitively + same port) now returns the advertised
string verbatim in the shared rewriter too (it re-serialised: added a trailing slash
and case-folded a case-only host difference);
- a real rewrite serialises via AbsoluteUri, not Uri.ToString(), which un-escaped the
advertised path (/x%20y became /x y) in the driver + browser;
- unusable URLs: the rewriter still falls back to the configured URL (driver/browser);
the client keeps its loud failure as call-site validation (null -> InvalidOperation,
unparseable -> UriFormatException).
Reuses the #806 rewrite cases plus the Client.Shared-specific edges (verbatim
no-op, case-only host difference, escaped path, loud failure on unusable
URLs). Green against the pre-#812 copy: 343/343.
Review of 3d1b86b4: OpcUaPublishActor installs a new authority generation
before applying its address space, and an apply that throws keeps the old one.
A scripted alarm moved from equipment A to B therefore stayed commandable with
A's grant under B's generation (briefly before the rebuild, or indefinitely
after a failed apply).
The generation now carries ScriptedAlarmOwners (ScriptedAlarmId -> EquipmentId,
decoded by ParseDataPlaneAuthority from the artifact's ScriptedAlarms rows, the
same rows the composition materialises from). AuthorizeScriptedCondition denies
unless the node manager's live binding names the same owner as the generation:
a moved alarm is denied under the old owner's, the new owner's and a Cluster
grant until the address space re-binds it; an alarm the generation no longer
deploys is denied. Install/apply order unchanged.
Tests: window (a) generation moved / binding stale => both owners and Cluster
denied, then rebuild under the new owner => new owner allowed, old denied;
window (b) apply failed after install => denied across clock and further
generations, then a successful rebuild restores the new owner only; undeployed
alarm denied; artifact decode of the owner map.
Scripted condition NodeIds are opaque ScriptedAlarmIds, so splitting them as a
topology path could never match an Equipment grant: a narrow equipment grant was
denied while a Cluster grant passed.
- OtOpcUaNodeManager binds each LIVE scripted condition instance to the
EquipmentId it was materialised under (only when it hangs under that folder);
dropped on remove / drop-recreate / equipment-subtree removal / rebuild; a
same-id re-materialise under another equipment re-parents and re-binds.
- DataPlaneAuthoritySnapshot carries EquipmentScopePaths (EquipmentId ->
[uns, Area, Line, Equipment]) decoded from the artifact by the same
AclScopePathResolver call that plants Equipment grants.
- DataPlaneAuthorizer.AuthorizeScriptedCondition re-reads key, grant and
generation per call (uncached) and evaluates at the owner path; unbound,
replaced or unplaceable owners deny under every grant. No id-split or
realm-root fallback.
- Native conditions (RawPath) and the ACL-off role gate are unchanged.
NodeIds and AlarmCommand.AlarmId are unchanged.
Sdk2OpaqueScriptedScopeBaselineTests deliberately flipped: it pinned the denial
and now pins owner-grant allow / sibling deny / cluster allow. Follow-up #808
(folder ids + Server-object event visibility for narrow UNS grants).
ShadowModeTests' runaway case asserted "slowest < 250 ms" around evaluations
whose timing included cold Roslyn compile/JIT of new script text, so it failed
on a healthy published path (540-880 ms measured, both SDK baselines).
The test now puts a test-owned barrier runner (GatedShadow) between the real
ShadowScriptRunner and the real worker pool. The runaway's first shadow run is
held before it reaches the pool, then (after it runs away in the worker, the
pool answers T and the worker is KilledDeadline with the runaway as culprit)
its outcome is held before comparison. Published evaluations made while a
barrier is closed must return the in-process values; a Mirror that waited for
its shadow hangs into a 30 s liveness failure (mutation-checked). Output
correctness, pool kill/quarantine, published-side never quarantined, the single
runaway mismatch (sibling is a victim, not compared) and key_busy drops are kept.
The wall-clock number moves to an opt-in Category=Perf case
(Shadow_published_path_latency_while_the_shadow_runs_away, OTOPCUA_SCRIPT_PERF=1)
on warmed evaluators, reporting hardware and load average.
Sibling: ContainmentTests' hard-deadline case timed the runaway's first
(cold-compile) run; it now compiles the runaway's source first with an input
that does not spin.
The 1.5.378.182 StatusAggregateCalculator (vendored as the application's
compatibility baseline) counts Uncertain regions as Good time under
TreatUncertainAsBad = false; 1.5.378.106 counted Good regions only, as Part 13
§5.4.3.31/§5.4.3.33 and Mantis 0006166 require. Our evaluator follows Part 13,
so the oracle moved, not the server: 10 SdkAggregateParityTests failed.
SdkAggregateOracle.Run now answers PercentGood through a subclass of the
baseline StatusAggregateCalculator that counts Good regions only (same bounds,
regions, status/Partial bits and configuration as PercentBad). RunSdkAsIs keeps
the untouched baseline. Rejected the proposed 100 - PercentBad under
TreatUncertainAsBad = true: that flag also changes the region machinery (the
end-of-data 1 ms rule), so it computes over a different total; pinned by a test.
New tests pin the divergence on hand-computed G/U/B/G (50 vs baseline 75) and
all-Uncertain (0/0 vs baseline 100) intervals, forward and reverse, plus a
data-starts-inside interval where oracle == baseline.
Sql.Common.Tests 265/275 -> 280/280.
The AdminUI OPC UA browse picker connected to the EndpointUrl the server
advertised in GetEndpoints verbatim, so behind NAT / a container port
publish it dialled the server's private hostname + internal port and
failed DNS where the runtime driver (which rewrites per #676) connected.
- Move the rewrite to the shared OpcUaEndpointUrlRewriter (.Contracts,
pure Uri logic, no SDK dependency) and the policy+mode selection to
OpcUaEndpointSelection (.Session leaf). Driver and browser both select
through it, so the browse connects exactly where the driver does.
- Policy/mode filter, server certificate and strict browse PKI
(no auto-accept) are unchanged.
- Unit tests: rewrite (host/port differ, same, IPv6 both sides, path
kept, port-less, scheme mismatch untouched), browser selection seam.
- Live NAT tests (Fixture=opc-plc-nat, OPCUA_NAT_ENDPOINT): browse via a
published port with a premise check that the advertised host:port
differs and does not resolve, nsu= round-trip, unreachable endpoint
fails cleanly, SignAndEncrypt reaches the server and is refused
BadCertificateUntrusted. Verified red without the rewrite.
