From fe26d6a2f80b57b119042aa94d726018004b7f9f Mon Sep 17 00:00:00 2001 From: Ido Shamun Date: Fri, 9 Jan 2026 23:02:07 +0200 Subject: [PATCH 01/19] feat: add schema isolation infrastructure for parallel Jest workers Add infrastructure for PostgreSQL schema isolation to enable parallel Jest workers within CI jobs. Each worker gets its own schema to prevent data conflicts between tests. Changes: - Add TYPEORM_SCHEMA env var support and auto-schema selection based on JEST_WORKER_ID when ENABLE_SCHEMA_ISOLATION=true - Set PostgreSQL search_path at connection level for raw SQL queries - Add createWorkerSchema() to copy table structures, views, and migrations data from public schema to worker schemas - Use pg_get_serial_sequence() for sequence resets to handle different sequence naming conventions Known limitation: Database triggers are not copied as they reference functions in the public schema. Schema isolation is opt-in via ENABLE_SCHEMA_ISOLATION=true environment variable.

FK constraint copying: Tables copied with INCLUDING ALL don't include FK constraints. Now explicitly copy FK constraints with correct schema references so CASCADE and SET NULL actions work properly. 2. Seed data copying: Copy critical seed data (ghost user '404', system user, system sources, etc.) to worker schemas so tests don't fail when expecting these records. 3. Trigger function search_path: Add SET search_path clause to plpgsql functions so unqualified table names in trigger bodies resolve to the correct worker schema instead of defaulting to public. 4. Hardcoded schema references: Remove explicit 'public.' references from cron jobs (updateViews, updateDiscussionScore, checkReferralReminder) so they work with schema isolation. 5. Increased beforeAll timeout to 60s to accommodate FK constraint copying.
