Notify.To(list).Send(subject,body) now generates a NotificationId GUID,
enqueues a Notification-category message into the site Store-and-Forward
Engine, and returns the NotificationId immediately (Task<string>). The
NotificationId is the single idempotency key end-to-end: it is the S&F
message Id, it is carried inside the buffered NotificationSubmit payload,
and it is the id the forwarder submits to central.
NotificationForwarder now deserializes the buffered payload as a
NotificationSubmit and reads NotificationId from it (re-stamping only the
site-owned SourceSiteId / SourceInstanceId), instead of deriving the id
from StoreAndForwardMessage.Id.
Adds NotifyHelper.Status(id): queries central via the site communication
actor; reports the site-local Forwarding state while the notification is
still buffered at the site, maps central's response when found, and
Unknown otherwise. Adds a NotificationDeliveryStatus record.
SiteCommunicationActor gains a NotificationStatusQuery forwarding handler
mirroring NotificationSubmit. StoreAndForwardService.EnqueueAsync gains an
optional messageId parameter and exposes GetMessageByIdAsync.
StoreAndForwardStorage.InitializeAsync opened a SqliteConnection against the
configured SqliteDbPath (default ./data/store-and-forward.db) without ensuring
the parent directory exists. SQLite creates the database file but not its
directory, so when data/ was absent the connection failed with
"SQLite Error 14: unable to open database file" — aborting the site host's
RegisterSiteActors at StoreAndForwardService.StartAsync.
This was the root cause of the six failing SiteActorPathTests. Production
masked it because the Docker image / deployment creates data/.
InitializeAsync now calls EnsureDatabaseDirectoryExists, which parses the
connection string and creates the parent directory of a file-backed database
(in-memory databases and bare filenames are skipped).
Regression test InitializeAsync_FileInMissingDirectory_CreatesDirectory fails
against the pre-fix code. Host suite now 155/155 green (was 149/155).
Resolves StoreAndForward-001, ExternalSystemGateway-001, NotificationService-001
— one systemic gap where buffered messages were persisted but never delivered,
and the active node never replicated its buffer to the standby.
Delivery handlers (ExternalSystemGateway-001 / NotificationService-001):
- AkkaHostedService registers delivery handlers for the ExternalSystem,
CachedDbWrite and Notification categories after StoreAndForwardService starts;
each resolves its scoped consumer in a fresh DI scope.
- ExternalSystemClient, DatabaseGateway and NotificationDeliveryService each
gain a DeliverBufferedAsync method: re-resolve the target and re-attempt
delivery, returning true/false/throwing per the transient-vs-permanent contract.
- EnqueueAsync gains an attemptImmediateDelivery flag; CachedCallAsync and
NotificationDeliveryService.SendAsync pass false (they already attempted
delivery themselves) so registering a handler does not dispatch twice.
Replication (StoreAndForward-001):
- ReplicationService is injected into StoreAndForwardService; a new BufferAsync
helper replicates every enqueue, and successful-retry removes and parks are
replicated too. Fire-and-forget, no-op when replication is disabled.
Tests: StoreAndForwardReplicationTests (Add/Remove/Park observed),
attemptImmediateDelivery behaviour, and DeliverBufferedAsync paths for each
consumer. Full solution builds; StoreAndForward/ExternalSystemGateway/
NotificationService suites green.
Move all package versions into Directory.Packages.props so every project
resolves a single consistent version. Consolidates the Roslyn packages
(Microsoft.CodeAnalysis.CSharp.Scripting/Workspaces) onto 5.0.0, which
resolves the pre-existing NU1608 version-skew error in the test projects.
Triage was painful on the old layout: a lone Site dropdown sat on a sparse
row, errors were truncated mid-sentence with a per-row View/Hide toggle
that on expand pushed an unwrapped <pre> through the table and shoved the
Actions column off-screen, all rows looked the same regardless of age or
attempt count, and OriginInstance — which tells you which instance
produced the failure — wasn't displayed at all even though the data was
on the entity.
This pass:
- Adds a real filter bar: Site, Category, Target system, Origin instance,
Age window, free-text search. Category/Target/Origin/Age/Search filter
the loaded page client-side; Site still drives the server query (and
changing site now auto-queries — one fewer click).
- Replaces the in-table expansion with an Offcanvas detail drawer.
Clicking a row slides in a side panel with full message ID + copy,
category label, origin, attempts, both timestamps in relative + absolute
form, the complete error (pre-wrap, scrollable), and big Retry / Discard
buttons. The table never overflows.
- Stacks Target + Method into one column (target in semibold, method
small/muted below) and surfaces Origin as a code-styled chip in a new
column ("—" muted when null).
- Severity left-border on each row, derived client-side from
AttemptCount/MaxAttempts and age of the last attempt: red when retries
are exhausted and last attempt was in the past hour, amber when
exhausted but stale, muted grey otherwise.
- Mini attempt progress bar under the n/max count, red when fully
exhausted and amber while partial.
- Relative timestamps ("5m ago", "1h ago", "2d ago") with absolute UTC on
hover via the title attribute — applies in both the table and the drawer.
- Bulk select: header checkbox selects the filtered set, per-row
checkboxes. When ≥1 selected, a sticky action strip slides in below the
filter bar offering Retry selected / Discard selected with the usual
confirm dialog. Toast reports per-item success/failure counts.
- Summary line next to the title: "N parked · K target systems · oldest
Xh ago" (and "(showing M of N)" when filters are active).
- ParkedMessageEntry contract extended additively with MaxAttempts,
Category, and OriginInstance so the UI has the data it needs for
severity, the category filter, and the new column.
- Bumped page size from 25 to 50 to better match the dense layout.
The Parked Messages page returned "Parked message handler not available"
because no actor was ever registered for ParkedMessages, and Retry/Discard
requests had no Receive at all (would have hit deadletters). On top of
that, StoreAndForwardService.StartAsync() was never called anywhere, so
the sf_messages SQLite table was never created and the retry timer never
ran — silently breaking all of S&F.
- New ParkedMessageHandlerActor bridges StoreAndForwardService.{Get,Retry,Discard}
using the Sender→Task→PipeTo pattern already used in DeploymentManagerActor.
- SiteCommunicationActor now routes ParkedMessageRetryRequest and
ParkedMessageDiscardRequest the same way as the existing Query handler.
- AkkaHostedService.RegisterSiteActors() resolves StoreAndForwardService,
calls StartAsync() to create the schema and start the timer, then
creates and registers the handler actor.
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.
