From 9e689dc9d88011a3964f0f459ea268409b87bf80 Mon Sep 17 00:00:00 2001 From: Oliver Kieselbach Date: Tue, 26 May 2026 16:33:46 +0200 Subject: [PATCH] =?UTF-8?q?feat(backend/backup):=20PR2=20=E2=80=94=20singl?= =?UTF-8?q?e-row=20restore=20+=20admin=20UI?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit POST /api/global/backups/{backupId}/restore-row (GA-only) with preview|commit modes. Preview scans the ETag-pinned NDJSON blob for the requested (pk, rk), diffs against the live row, and returns rowSha256 + currentETag for echo. Commit re-validates everything under a short maintenance lease and writes via UpdateEntity(IfMatch=etag, Replace) or AddEntity; 412/404/409 → CurrentRowChanged. Backend: - RestoreTablePreflightValidator (no I/O) + BackupRestoreInputValidator (manifest parse, entry check, BlobName canonical, ETag-pin + SHA in one stream read) - CriticalTableRestoreService with PreviewRowAsync (no lease) + CommitRowAsync (MaintenanceLeaseHolder, 45 s renewal, deterministic finally release) - BlobBackupStore.OpenNdjsonReadAsync — GetProperties + OpenRead(IfMatch=etag) - BackupTerminalException carries a stable Code for HTTP envelope mapping - OpsEventService.RecordBackupRowRestoredAsync (Warning; payload is container + blobName only, never a SAS URL) - 27 new xUnit tests; full backend suite 1979/1979 green Web: - /admin/backups list page with newest-first list + "Run backup now" trigger and async job-status poller - /admin/backups/{backupId} detail page with per-table breakdown + single-row restore trigger - RestoreRowDiffModal with Added/Removed/Changed/Unchanged pills and auth-table security banner (GlobalAdmins/TenantAdmins/McpUsers) - api.backups namespace + matching DTO types - globalNavConfig: ga-backups under Ops - BackupRowRestored registered in OPS_EVENT_TYPES (dual-register policy) - 6 new vitest cases;
