From cb07f67a695fc2316e517f15252245e8dc301f38 Mon Sep 17 00:00:00 2001 From: Oier Bravo Urtasun Date: Mon, 13 Apr 2026 02:55:55 +0200 Subject: [PATCH] feat(realtime): full Fase 2b.0 test suite + infra hardening MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Extend the 2b.0 red-phase coverage: presence, RLS isolation, offline-queue contract, and Playwright scaffolds for the shopping-session UX. Only the presence test is blocked on an upstream Realtime bug (documented below); all other Realtime paths are proven end-to-end. Tests - realtime-postgres-changes.test.ts: now uses afterEach socket disconnect (Vitest singleFork kept Phoenix sockets alive between files, leaking state) - realtime-isolation.test.ts (new): R-I-01 David (guest, same collective) receives events; R-I-02 Eva (non-member) receives NONE β€” RLS is enforced server-side per subscribed JWT - realtime-presence.test.ts (new, describe.skip): two-client roster + leave assertions ready, gated on upstream bug - sync-queue.test.ts (new, describe.skip): 7 placeholders pinning the apps/web/src/lib/sync/queue.ts contract (Q-01..Q-04 enqueue / in-order flush / retry; F-01..F-03 online-event flush + last-write-wins) - apps/web/tests/e2e/{session,realtime,offline}.test.ts (new, describe.skip): S-01..S-03, R-E-01, R-E-02, O-01, O-02 pinning the Modo Compra UI contract - vitest.config.ts: fileParallelism=false, drop singleFork so each file gets a fresh worker fork β€” prevents RealtimeClient singleton leakage Infra - db-init/00-role-passwords.sh: pre-create `realtime` schema with AUTHORIZATION supabase_admin. Realtime's per-tenant migrator creates tables INSIDE the schema but does not create the schema itself; without this the first tenant connect fails with "schema realtime does not exist" - docker-compose.dev.yml: adopt the upstream supabase/supabase Realtime env shape β€” SEED_SELF_HOST=true + RUN_JANITOR=true + RLIMIT_NOFILE=10000 + drop the custom `command: eval seeds` (that bypasses the normal supervisor startup and was observed to cause GenServer crashes under load). Version pinned to v2.76.5 to match the official docker-compose. Known upstream bug - Realtime v2.76.5 and v2.83.0 both crash on presence_diff: `(UndefinedFunctionError) RealtimeChannel.handle_out/3 is undefined`. postgres_changes + isolation unaffected (they don't traverse handle_out). Presence tests stay `describe.skip` until a fixed upstream is released.
