Migration Consolidation - January 16, 2025

Summary

Consolidated 18 separate database migration files into 5 logically organized migrations for better maintainability and clarity in this early-stage project.

Changes Made

Migration Structure

Before: 18 migration files

• 12 initial table creation files (20240101 series)
• 6 patch/fix files (20240102-20240103 series)

After: 5 consolidated migration files

1. 20250101000001_initial_setup.sql - Schema, enums, shared functions
2. 20250101000002_core_tables.sql - Pack, runtime, worker, identity, permissions, policy, key (7 tables)
3. 20250101000003_event_system.sql - Trigger, sensor, event, enforcement (4 tables)
4. 20250101000004_execution_system.sql - Action, rule, execution, inquiry (4 tables)
5. 20250101000005_supporting_tables.sql - Notification, artifact (2 tables)

What Was Consolidated

Each new migration incorporates all patches and fixes:

1. Initial Setup - Combined:

   • Schema creation
   • All 12 enum type definitions
   • Shared update_updated_column() function

2. Core Tables - Combined:

   • Pack table with all indexes (including performance indexes)
   • Runtime and worker tables
   • Identity table with password_hash column (from patch 20240102000001)
   • Permission_set, permission_assignment, policy tables
   • Key table with ownership validation

3. Event System - Combined:

   • Trigger table
   • Sensor table with config column (from patch 20240103000001) and CASCADE foreign keys (from patch 20240102000002)
   • Event table
   • Enforcement table (with forward reference to rule)

4. Execution System - Combined:

   • Action table
   • Rule table with action_params and trigger_params columns (from patches 20240103000003 and 20240103000004)
   • Execution table with proper identity foreign key
   • Inquiry table with proper identity foreign key
   • All foreign key constraints resolved (no forward references)

5. Supporting Tables - Combined:

   • Notification table with pg_notify trigger
   • Artifact table
   • All performance optimization indexes from 20240101000012

Forward Reference Handling

The old migrations had circular dependencies between tables. The new structure properly handles this:

• Migration 2 creates policy and key tables with forward references to action/sensor (without FK constraints)
• Migration 3 adds sensor foreign key to key table
• Migration 4 adds action foreign key to policy and key tables, plus rule foreign key to enforcement table

Old Migrations

All 18 old migration files were moved to migrations/old_migrations_backup/ for reference and can be safely deleted after verification.

Benefits

1. Easier to understand - 5 files vs 18 files, clear logical grouping
2. Cleaner history - All patches incorporated into base migrations
3. Better documentation - Each file has clear sections with comments
4. Reduced complexity - No need to track patch dependencies
5. Fresh start - Since there are no production deployments yet, this is the perfect time to consolidate

Testing Status

• Test fresh database creation with new migrations
• Verify all foreign key constraints are correct
• Verify all indexes are created
• Test that SQLx compile-time checking still works
• Run existing integration tests (if any)
• Fix sensor service compilation error with missing trigger_params field
• Fix sensor service test compilation error with missing trigger_params field

Issues Fixed During Consolidation

1. Sensor Service Rule Query

Issue: attune-sensor failed to compile after migration consolidation due to missing trigger_params field in Rule query.

Error:

error[E0063]: missing field `trigger_params` in initializer of `attune_common::models::Rule`
   --> crates/sensor/src/rule_matcher.rs:114:13

Root Cause: The find_matching_rules() query in rule_matcher.rs was selecting Rule columns but missing the newly added trigger_params field.

Fix: Added trigger_params to the SELECT clause in crates/sensor/src/rule_matcher.rs:129:

// Before:
conditions,
action_params,
enabled,

// After:
conditions,
action_params,
trigger_params,
enabled,

Status: ✅ Fixed - Compilation error resolved

2. Sensor Service Test Rule Creation

Issue: Test code failed to compile due to missing trigger_params field in Rule struct initialization.

Error:

error[E0063]: missing field `trigger_params` in initializer of `attune_common::models::Rule`
   --> crates/sensor/src/rule_matcher.rs:498:9

Root Cause: The test_rule() helper function in tests was creating a Rule instance but missing the newly added trigger_params field.

Fix: Added trigger_params field to test Rule initialization in crates/sensor/src/rule_matcher.rs:499:

fn test_rule() -> Rule {
    Rule {
        action_params: serde_json::json!({}),
        trigger_params: serde_json::json!({}),  // <-- Added this line
        id: 1,
        // ... rest of fields
    }
}

Status: ✅ Fixed - Test compilation error resolved

Next Steps

1. Test the new migrations on a clean database:

   dropdb attune_test && createdb attune_test
   DATABASE_URL="postgresql://postgres:postgres@localhost/attune_test" sqlx migrate run
   

2. Verify all tables, indexes, and constraints:

   psql -U postgres -d attune_test -c "\dt attune.*"
   psql -U postgres -d attune_test -c "\di attune.*"
   

3. Update any documentation that references old migration files

4. After successful verification, delete migrations/old_migrations_backup/

Notes

• All enum types (12 total) preserved exactly
• All constraints and validation triggers preserved
• All indexes (including GIN indexes) preserved
• All comments preserved and enhanced
• pg_notify trigger for notifications preserved
• Key ownership validation trigger preserved
• Proper CASCADE and SET NULL behaviors maintained

Post-Consolidation Fixes

Files Modified

• crates/sensor/src/rule_matcher.rs - Added missing trigger_params field to Rule query (line 129)
• crates/sensor/src/rule_matcher.rs - Added missing trigger_params field to test Rule initialization (line 499)

Compilation Status

• ✅ Sensor service compilation error fixed (Rule query)
• ✅ Sensor service test compilation error fixed (test_rule helper)
• ✅ No more missing field errors in workspace
• ⏳ SQLx cache needs update (cargo sqlx prepare)
• ⏳ Full workspace compilation pending database setup
