13 well-bounded test-coverage gaps closed across 11 test projects.
Net +35 regression tests; no production code changes except the
SiteEventLogger src reference unchanged (W3 redacted only test code).
Test additions:
- CLI-022: CommandTreeTests pinned-count assertion bumped 14→16 and
3 InlineData rows added for the audit + bundle command groups.
- Commons-020: new TransportRecordsTests covers BundleManifest /
ExportSelection / ImportPreview / ImportResolution / ImportResult —
ctor + System.Text.Json round-trip + record-equality (14 tests).
- CD-024: SPLIT-RANGE failure-continuation now under
EnsureLookahead_SecondSplitThrows_LoopAborts_FirstBoundaryStillCommitted
(Skippable MS-SQL fixture); production-shape rowversion delete
asserted by DeleteDeploymentRecord_CurrentRowVersion_StubAttachPath_DeleteSucceeds.
- CentralUI-033: new QueryStringDrillInTests with 4 bUnit cases for
Transport + SiteCalls drill-in / query-string handling.
- DM-024: probe actors (ReconcileProbeActor, SerializationProbeActor,
ArtifactProbeActor) refactored from static fields to per-test instances
(Interlocked on counter) — all 31 callers updated; no production
changes required.
- HM-022: real-time PeriodicTimer test flake fixed by replacing
fixed-budget Task.Delay with a RunLoopUntil poll-until-condition
helper (5s/25ms). Production loop untouched.
- InboundAPI-023: new EndpointExtensionsTests covers the
POST /api/{methodName} composition wiring via TestServer (7 cases:
happy path, missing key 401, unknown method 403, invalid JSON 400,
missing param 400, script-throws 500 sanitised, AuditActorItemKey
stash invariant).
- MgmtSvc-021: 6 new ManagementActorTests cover the Transport bundle
handlers (role gate for Export/Preview/Import, unknown-name
ManagementCommandException, blocker-rejection, dedupe last-write-wins).
- SCA-006: SiteCallQueryRequest_StuckOnly_CursorAtNonStuckBoundary_SkipsToNextStuckRow
pins the missing boundary case.
- SEL-023: stress-test `bool stop` promoted to `volatile bool` for
cross-thread visibility under release/JIT.
Verify-only resolutions:
- NS-024: closed by NS-019 (commit ac96b83 deletion of
NotificationDeliveryService + its test file). No edits needed.
- NotifOutbox-008: FallbackMaxRetries/FallbackRetryDelay are private
forward-compat constants returned only when no SMTP-config row exists
(in which case EmailNotificationDeliveryAdapter returns Permanent,
bypassing the values entirely). Marked Resolved with note.
- Transport-010: Overwrite child-collection sync covered by the T-001/
T-002 tests added in commit e3ca9af; per-IP throttle by
BundleUnlockRateLimiterTests; failed-session retention by
BundleSessionStoreTests; T-009 closed structurally via AsyncLocal.
Marked Resolved by reference.
Build clean; all 11 affected test suites green. README regenerated:
33 open (was 46).
Well-localised perf fixes across 8 modules.
Lock decoupling / SQL streaming:
- AuditLog-005: SqliteAuditWriter gains dedicated read-only _readConnection
(+ _readLock) backed by WAL journal mode. GetBacklogStatsAsync,
ReadPendingAsync, ReadPendingSinceAsync, ReadForwardedAsync no longer
contend with the hot-path INSERT lock — backlog probes on a 30s timer
can't stall the writer under multi-hundred-K Pending backlog.
- SEL-022: dropped Cache=Shared from SiteEventLogger's default connection
string (single-connection logger; mode was dormant config).
Memory / streaming:
- CLI-019: bundle export streams base64 in 1 MB-aligned chunks via
Convert.TryFromBase64Chars straight into the FileStream — no more
full-bundle byte[] allocation.
- CentralUI-031: TransportImport now stages the upload to a per-session
temp file under Path.GetTempPath() (replaces in-memory byte[] field);
page implements IDisposable to delete the temp file on reset / new
upload / dispose. Per-circuit working set drops from ~100 MB to ~80 KB.
N+1 hoisting:
- Transport-008: added ITemplateEngineRepository.GetTemplatesWithChildrenAsync
bulk method; BundleImporter.PreviewAsync calls it once instead of per-
template-name. Single query with .Include(...).AsSplitQuery().
- DM-023: BuildDeployArtifactsCommandAsync's per-site loop now references
a pre-fetched GlobalArtifactSnapshot (shared scripts, external systems,
DB connections, notification lists, SMTP) instead of re-querying per site.
- MgmtSvc-023: HandleQueryDeployments unfiltered branch uses one
GetAllInstancesAsync bulk load + Dictionary<int,int?> lookup (was a
GetInstanceByIdAsync per record).
Small allocations / per-tick rebuilds:
- InboundAPI-019: AuditWriteMiddleware gates EnableBuffering() on
RequestHasBody() so GET/HEAD/DELETE/TRACE/OPTIONS and Content-Length:0
requests skip the FileBufferingReadStream allocation.
- NotifOutbox-006: ResolveAdapters dictionary now cached on
_adaptersCache (built lazily on first sweep) + actor-lifetime
_adaptersScope; ResolveAdapters no longer rebuilds per dispatch tick.
Verify-only:
- Comm-017: Confirmed _inProgressDeployments was deleted by Comm-016 in
commit ac96b83 — marked Resolved with that attribution. No code change.
Doc-correction:
- NS-022: Updated MailKitSmtpClientWrapper XML doc to spell out single-
connection / per-delivery-factory contract (option (b) — transient
client per Send — rejected because it re-handshakes TLS per email).
10+ new regression tests across 8 test projects. Build clean; affected
suites all green. README regenerated: 54 open (was 65).
Replace SiteDataConnectionAssignment join table with a direct SiteId FK on DataConnection,
simplifying the data model, repositories, UI, CLI, and deployment service.
- SiteExternalSystemRepository and SiteNotificationRepository registered in Site DI
- Removed AddConfigurationDatabase from Site role in Program.cs
- Removed ConfigurationDb from appsettings.Site.json
- ArtifactDeploymentService collects all 6 artifact types including data connections and SMTP
