What

Comprehensive real-Postgres regression coverage for the boot-time migration runner + the previously-untested Redis online-status layer, filed under SOP rule internal#765 (regression-coverage). test_layer: real-postgres.

New files (workspace-server/internal/db/):

  1. postgres_replay_integration_test.go (//go:build integration, real PG via INTEGRATION_DB_URL)

    • TestIntegration_MigrationReplay_FromScratch — resets public to a blank schema and runs the production db.RunMigrations entrypoint over the full forward chain (all .up + legacy .sql; 68 forward of 118 files today), with hard-fail semantics. Asserts: every forward migration recorded (zero silent skips), zero .down.sql recorded (#211 signature), load-bearing tables present (workspaces, workspace_auth_tokens — the #211 canary, delegations, activity_logs), and agent_memories absent at HEAD (proves the late drop ran after its early create → ordering held).
    • TestIntegration_MigrationReplay_IsIdempotent_DoubleApply — runs the full chain twice against the same DB; second pass must apply zero new files and not error. Guards the 045 crash-loop class (cp#429): a non-idempotent migration replays fine once and fails on the second boot.
    • TestIntegration_InitPostgres_PingSucceeds / ..._BadDSNFails — real InitPostgres ping + SELECT 1 round-trip; bad-DSN path proves the DB.Ping() check is load-bearing.
  2. redis_test.go (plain unit, miniredis = real RESP + real TTL semantics; runs in ci.yml Platform (Go))

    • Key naming + value + TTL for SetOnline/IsOnline/RefreshTTL (ws:<id>), CacheURL/GetCachedURL (ws:<id>:url), CacheInternalURL/GetCachedInternalURL (ws:<id>:internal_url), and ClearWorkspaceKeys.
    • TestLivenessTTL_ExceedsHeartbeatWindow pins LivenessTTL >= 5 × 30s (regressing toward the old 60s reintroduces false-positive restart cycles).
    • TestIsOnline_TrueThenExpires / TestRefreshTTL_ExtendsLiveness drive miniredis's clock (FastForward) to exercise real TTL expiry.
    • TestKeyNamespacesDoNotCollide — the three key namespaces must stay distinct (a collapse would serve a URL as a liveness value fleet-wide).

CI wiring:
3. handlers-postgres-integration.yml — new "Migration replay-from-scratch gate (#2150)" step runs the integration-tagged db tests against a separate molecule_replay database on the same sibling Postgres (so the destructive DROP SCHEMA never touches the handlers molecule DB; no ordering coupling).
4. detect-changes.pyhandlers-postgres profile now also triggers on workspace-server/internal/db/**, so a change to redis.go/postgres.go runs this gate.

Why this closes a real gap

The existing db tests are sqlmock-only (postgres_migrate_test.go, postgres_schema_migrations_test.go) — they pin which statements fire but can't execute SQL, so they cannot prove the chain replays. The existing CI psql loop in handlers-postgres-integration.yml deliberately skips failing migrations (⊘ skipped), so it stays green even if the chain stops replaying. redis.go had no test at all. Mock-only does not satisfy #765 — these use the real layer.

Watch-fail intent (regression-first)

  • Reintroduce *.sql globbing without the .down.sql filter (#211) → a DROP runs before its CREATEFromScratch errors / table-presence assertions fail.
  • Add a non-idempotent migration (045 class) → DoubleApply fails on the second pass.
  • Mis-order / dangling-dependency migration → RunMigrations returns non-nil → FromScratch fails.
  • Drift a ws:%s... key format or shrink LivenessTTL → a redis_test.go case fails.

What CI + CR2 must confirm (DRAFT — I cannot compile/run locally)

  • go build ./... and go vet pass (imports/signatures; miniredis/v2 v2.37.0, lib/pq, go-redis/v9 already in go.mod).
  • ci.yml Platform (Go) runs the new redis_test.go cases green (no build tag).
  • handlers-postgres-integration.yml runs the new replay-from-scratch step green against the 118-file chain — i.e. confirm the full forward chain actually replays today (the 031_memories_pgvector EXCEPTION guard must absorb the missing vector extension on postgres:15-alpine; if it does not, the gate would correctly fail and we'd need an extension-present runner or a documented skip).
  • createdb/psql is on the runner PATH for the molecule_replay create step (postgres client is already used by the surrounding migration step).
  • architecture_test.go (db-is-a-leaf) stays green — new imports are confined to _test.go files, which it skips.

Notes / caveats

  • The workflow's integration job carries the inherited continue-on-error: true (mc#1982 mask) — so this gate surfaces failures but does not yet hard-block merge until that mask is lifted for the job. CR2/CTO: flag if #2150 wants this promoted to a required, non-masked check.
  • redis_test.go uses miniredis (in-process Redis with real RESP + TTL), the repo's established Redis test layer and already a dependency — there is no real-redis CI service; this exercises actual go-redis calls and real expiry, not a mock.

Approved on head 6ad6e4a21d.

5-axis review:

  • Correctness: the migration replay tests use the production RunMigrations entrypoint against a reset real Postgres schema, count the forward migration set, reject .down.sql application, check load-bearing tables, and run a second pass to cover idempotent boot behavior. InitPostgres tests cover real ping success and bad-DSN failure. Redis tests call the real package functions against miniredis and assert key names, values, TTLs, expiry, refresh, and namespace separation.
  • Robustness: destructive schema reset runs against a dedicated molecule_replay database in CI, separate from the handlers integration DB. Path-filter widening ensures internal/db changes trigger the Postgres integration job.
  • Security: no secret handling introduced; tests focus on migration/auth substrate integrity and Redis liveness routing keys.
  • Performance: integration tests are behind the existing handlers-postgres workflow and integration tag; Redis tests are in-process.
  • Readability: comments clearly explain watch-fail intent and why existing skip-tolerant psql replay was insufficient.

Caveat: PR title is still WIP and Gitea reports it not mergeable; approval is for the reviewed test implementation. Local Go was not run in this runtime because go is unavailable; Gitea CI shows Platform Go and Handlers Postgres Integration green.

RC @6ad6e4a21d836f57bce6551ccb57d4c655e5771c

The test intent is sound, but this head is not mergeable against current main. Gitea reports mergeable=false, and a local git merge origin/main reproduces content conflicts in .gitea/scripts/detect-changes.py and .gitea/workflows/handlers-postgres-integration.yml. Please rebase/reconcile those workflow/change-detection conflicts before this can be a merge-ready 2nd-genuine approval.

5-axis notes after diff inspection: the migration replay and Redis tests are directionally correct and security/robustness-positive, with no secret exposure or production runtime path change. The blocker is integration safety/current-head mergeability, not the test concept. Required contexts on the stale conflicted head show green, and concierge/Staging-SaaS E2E remains out-of-scope known #3164, but required green does not override a non-mergeable conflicted PR head.
