| 1 | #!/usr/bin/env bash |
| 2 | # deploy/migrate-test.sh — Test migrations against a production data snapshot |
| 3 | # |
| 4 | # USAGE: |
| 5 | # ./deploy/migrate-test.sh [snapshot.sql.gz] |
| 6 | # |
| 7 | # If no snapshot is given the script creates a fresh pg_dump from the live DB. |
| 8 | # |
| 9 | # WHAT IT DOES: |
| 10 | # 1. Creates a temporary test database (musehub_migrate_test_<timestamp>) |
| 11 | # 2. Restores the snapshot into it |
| 12 | # 3. Runs alembic upgrade head |
| 13 | # 4. Verifies alembic_version == HEAD |
| 14 | # 5. Runs alembic downgrade -1 (one step back) |
| 15 | # 6. Runs alembic upgrade head again (round-trip check) |
| 16 | # 7. Drops the temporary database |
| 17 | # 8. Exits 0 on success, 1 on any failure |
| 18 | # |
| 19 | # Run this BEFORE applying migrations to production. |
| 20 | # |
| 21 | # REQUIREMENTS: |
| 22 | # - psql and pg_dump/pg_restore in PATH |
| 23 | # - Environment variables (or .env): |
| 24 | # DATABASE_URL postgresql+asyncpg://user:pass@host/dbname |
| 25 | # PG_ADMIN_URL postgresql://user:pass@host/postgres (for CREATE/DROP DB) |
| 26 | # - Python env with alembic + app deps activated |
