Eliminates the per-page <ConfirmDialog @ref="_confirmDialog"
ConfirmButtonClass="btn-danger" /> boilerplate. Pages now inject
IDialogService and call ConfirmAsync(title, message, danger: true)
programmatically.
New scoped service holds a single active dialog (throws on nested
calls), with a global DialogHost mounted once in MainLayout that
renders the modal markup, owns body scroll-lock via Bootstrap's
modal-open class, traps focus on the modal element, and handles
Escape-to-cancel.
Same service also exposes PromptAsync, used to replace the bespoke
NewFolderDialog. Both ConfirmDialog and NewFolderDialog components
are deleted — their callers (~13 pages across Admin/Design/Deployment
/Monitoring) now go through the service.
DiffDialog stays as-is — different use case (before/after content).
bUnit tests in TopologyPageTests, DataConnectionsPageTests, and
TemplatesPageTests register IDialogService in their service
collection.
Also: a top-of-file Razor comment on Sites.razor pointing future
implementers at it as the reference list-page pattern.
LdapMappings: flex header, search filter, per-row Edit + kebab Delete,
@key, dropped Site-Scope-Rules cell in favor of a {n rule(s)} badge.
LdapMappingForm: two stacked cards (Mapping then Site Scope Rules);
scope rules render as removable chips with an inline "Add scope rule"
form; create-mode disables the scope card with an explainer; role
select gets form-text help.
DataConnections: <h4> in flex header, Bulk actions dropdown holding
Expand/Collapse, hover-visible kebab on tree nodes mirroring the
right-click context menu, aria-labels, "No connections match the
filter." inline empty state.
DataConnectionForm: Site rendered as readonly plaintext + lock-after-
creation note in edit mode; parallel Primary endpoint / Backup endpoint
headings; "Optional" badge on Backup when null; form-text on
FailoverRetryCount.
ApiKeys: search filter, Status column dropped (state now lives in the
kebab menu label "Disable"/"Enable"), Edit + kebab actions, @key,
aria-labels.
ApiKeyForm: nested card removed; fixed-text Back header; real
clipboard copy via IJSRuntime + toast confirmation.
Test selector fix in DataConnectionFormTests for the new Site
readonly-plaintext rendering.
Three new sections inserted into <OpcUaEndpointEditor>:
1. Authentication (between the existing Connection row and Timing)
- 'Enable Authentication' button when Config.UserIdentity is null
- TokenType select (Anonymous / UsernamePassword / X509Certificate)
- Conditional Username + Password inputs for UsernamePassword
- Conditional Certificate path + Certificate password for X509Certificate
- 'Remove Authentication' button
2. Advanced subscription (after the existing Subscription row)
- Subscription display name (text)
- Subscription priority (number 0-255)
- Timestamps to return (Source / Server / Both select)
- Discard oldest (checkbox)
3. Deadband filter (after Advanced subscription)
- 'Enable Deadband' button when Config.Deadband is null
- Type select (Absolute / Percent), Value number input
- 'Remove Deadband' button
EnableAuthentication and EnableDeadband helpers complement EnableHeartbeat.
All new fields use the existing RenderFieldError helper for validator errors.
82/82 CentralUI tests pass (the 10 new editor tests drove the design).
Adds 11 new tests covering:
- Roundtrip of DiscardOldest/SubscriptionPriority/SubscriptionDisplayName/TimestampsToReturn
- Roundtrip of UserIdentity sub-object across all three TokenTypes
- Roundtrip of Deadband sub-object
- ToFlatDict/FromFlatDict for UserIdentity.* and Deadband.* dotted keys
- Validator rules: empty SubscriptionDisplayName, UsernamePassword w/o Username,
X509 w/o CertificatePath, Deadband Value <= 0, prefix propagation
Build passes; tests fail because serializer/validator have not been extended yet
(TDD red phase). Task B2 will implement the changes to drive them green.
Brings the Data Connections admin page up to the same UX standard as the
Topology page:
- Search box with dim non-matches (opacity 0.4, shape preserved)
- Toolbar: + Connection (disabled until a site is selected), Refresh,
Expand, Collapse
- Site context menu gains "Add Connection here" that navigates with
?siteId= so the form preselects + locks the Site field
- Form gains "Primary Endpoint" / "Backup Endpoint" h6 subsection
headers matching the SiteForm convention; Failover Retry Count moved
inside the Backup subsection
- URL renamed: /admin/connections (primary) + /admin/data-connections
(legacy secondary @page). Same dual-route treatment on the form
- Nav label: "Data Connections" -> "Connections"
- Adds DataConnectionsPageTests bUnit suite (6 tests)
Single /deployment/topology page replaces /deployment/instances (legacy URL
preserved as a secondary @page directive) and the /admin/areas* CRUD pages.
TreeView with Site → Area → Instance, V1–V7 visual guide (bi-building /
bi-diagram-3 / bi-box), always-visible empty containers, search dim, F2
inline area rename, and right-click context menus per node kind (Add Area,
Move to Area…, lifecycle actions, etc.).
Adds AreaService.MoveAreaAsync with cycle prevention, same-site enforcement,
and name-collision check at the new parent. Instance rename intentionally
out of scope — UniqueName is the site-side actor identity, requires its own
design pass.
Right-click a template now offers "New Derived Template" — opens
TemplateCreate with the parent pre-selected via a new ?parentId query
parameter. Composition rows in the tree drop the trailing
"→ TargetName" muted text; the kind glyph plus the instance name carry
enough meaning, and the composed template is one click away from the
row's right-click menu.
Template inheritance is set once at create time and immutable on update.
UpdateTemplateAsync now returns "Parent template cannot be changed after
creation." when the caller sends a parent that differs from the stored
value — server-side enforcement covers UI, ManagementService, and CLI.
TemplateEdit renders the parent as static plaintext rather than an
editable dropdown; TemplateCreate's parent picker is unchanged.
Templates page is now a tree-only browser; editing happens on a dedicated
TemplateEdit page. Drag-drop is replaced by context-menu Move-to-Folder.
TreeView gains Bootstrap Icons (chevron + per-kind glyphs), ancestor guide
lines, defined hover/selected/focus tokens, and Escape-dismisses-menu per
the new Visual Design Guide (V1-V7) in Component-TreeView.md.
Restore inside the docker build was failing because TreatWarningsAsErrors
promotes NU1902/NU1903/NU1904 (vulnerable package warnings) to errors.
Bump the flagged packages to advisory-free versions:
- MailKit 4.15.1 -> 4.16.0 (GHSA-9j88-vvj5-vhgr)
- Microsoft.AspNetCore.DataProtection.EFCore 10.0.5 -> 10.0.7 (GHSA-9mv3-2cwr-p262, transitively pulls fixed System.Security.Cryptography.Xml — GHSA-37gx-xxp4-5rgx, GHSA-w3x6-4m5h-cxqf)
- OpenTelemetry.Api (transitive via Akka.Hosting) 1.9.0 -> 1.15.3 (GHSA-g94r-2vxg-569j, GHSA-8785-wc3w-h8q6) — added as a direct PackageReference in ScadaLink.Host to override the Akka.Hosting pin
To resolve the NU1605 downgrade chain triggered by DataProtection.EFCore
10.0.7 (which transitively requires Microsoft.EntityFrameworkCore >= 10.0.7
and friends), bump every Microsoft.* 10.0.5 reference across src/ and
tests/ to 10.0.7 in lockstep.
LmxProxy is no longer needed. Moved the entire lmxproxy/ workspace, DCL
adapter files, and related docs to deprecated/. Removed LmxProxy registration
from DataConnectionFactory, project reference from DCL, protocol option from
UI, and cleaned up all requirement docs.
Previously, failover only triggered when ConnectAsync failed consecutively.
If a connection succeeded but went stale quickly (e.g., heartbeat timeout),
the failure counter reset on each successful connect and failover never
triggered.
Added a separate _consecutiveUnstableDisconnects counter that increments
when a connection lasts less than StableConnectionThreshold (60s) before
disconnecting. When this counter reaches failoverRetryCount, the actor
fails over to the backup endpoint. Stable connections (lasting >60s)
reset this counter.
The original connection-failure failover path is unchanged.
Composable StaleTagMonitor class in Commons fires a Stale event when no
value is received within a configurable max silence period. Integrated
into both LmxProxyDataConnection and OpcUaDataConnection adapters via
optional HeartbeatTagPath/HeartbeatMaxSilence connection config keys.
When stale, the adapter fires Disconnected triggering the standard
reconnect cycle. 10 unit tests cover timer behavior.
Replace raw dictionary casting with ScriptParameters wrapper that provides
Get<T>, Get<T?>, Get<T[]>, and Get<List<T>> with clear error messages,
numeric conversion, and JsonElement support for Inbound API parameters.
Thread backup data connection fields through management command messages,
ManagementActor handlers, SiteService, site-side SQLite storage, and
deployment/replication actors. The old --configuration CLI flag is kept
as a hidden alias for backwards compatibility.
Update CreateConnectionCommand to carry PrimaryConnectionDetails,
BackupConnectionDetails, and FailoverRetryCount. Update all callers:
DataConnectionManagerActor, DataConnectionActor, DeploymentManagerActor,
FlatteningService, and ConnectionConfig. The actor stores both configs
but continues using primary only — failover logic comes in Task 3.
Switches from v1 string-based proto stubs to the production LmxProxyClient
(v2 native TypedValue protocol) via project reference. Deletes 6k+ lines of
generated proto code. Preserves ILmxProxyClient adapter interface for testability.
Replace SiteDataConnectionAssignment join table with a direct SiteId FK on DataConnection,
simplifying the data model, repositories, UI, CLI, and deployment service.
Move all CRUD create/edit forms from inline on list pages to dedicated form pages
with back-button navigation and post-save redirect. Add Playwright Docker container
(browser server on port 3000) with 25 passing E2E tests covering login, navigation,
and site CRUD workflows. Add POST /auth/token endpoint for clean JWT retrieval.
Switch site host to WebApplicationBuilder with Kestrel HTTP/2 gRPC server,
add GrpcPort/keepalive config, wire SiteStreamManager as ISiteStreamSubscriber,
expose gRPC ports in docker-compose, add site seed script, update all 10
requirement docs + CLAUDE.md + README.md for the new dual-transport architecture.
