v0.23.1: migration rollback capability
- Add rollbackMigration() function in db/database.js with transaction safety - Add POST /api/admin/migrations/rollback endpoint (admin-only) - Rollback SQL for v0.44 (indexes), v0.45 (audit_log table), v0.46 (cycle columns) - Error codes: NOT_APPLIED (404), ROLLBACK_NOT_SUPPORTED (422) - Audit logging for rollback events - Fix duplicate migrationStartTime declaration from v0.23.0 commit - Fix broken migration completion audit log from v0.23.0 commit - Fix DB path exposure (uses path.basename() now)

|
||||
| Agent | Status | Time | Notes |
|
||||
|-------|--------|------|-------|
|
||||
| Neo | ❌ FAILED | 21m | Attempted rollback but broke code (syntax errors, no actual implementation) — reverted |
|
||||
| Ripley | ✅ COMPLETED | — | Implemented rollback from scratch, fixed v0.23.0 structural bugs |
|
||||
| Bishop | ✅ COMPLETED | 4m | Verified build passes, container starts clean |
|
||||
| Hudson | ⬜ PENDING | — | Security audit dispatched |

**Files modified:** `db/database.js`, `routes/admin.js`, `client/lib/version.js`, `package.json`, `HISTORY.md`, `FUTURE.md`
|
||||
|
||||
**Work Completed:**
|
||||
- [x] `db/database.js`: Added `rollbackMigration()` function with transaction support, rollback SQL map for v0.44/v0.45/v0.46
|
||||
- [x] `db/database.js`: Fixed duplicate `migrationStartTime` declaration from v0.23.0 commit
|
||||
- [x] `db/database.js`: Fixed duplicate else block in runMigrations() from v0.23.0 commit
|
||||
- [x] `db/database.js`: Fixed DB path exposure (uses `path.basename()` now)
|
||||
- [x] `routes/admin.js`: Added `POST /api/admin/migrations/rollback` endpoint (admin-only)
|
||||
- [x] `routes/admin.js`: Imported `rollbackMigration` from database.js
|
||||
- [x] Version bumped to 0.23.1
|
||||
- [x] Docker build passes, container starts, migrations apply correctly
|
||||
- [x] Rollback tested: v0.46 rolled back successfully, v0.40 returns ROLLBACK_NOT_SUPPORTED, v0.99 returns NOT_APPLIED

### No Rollback Capability for Failed Migrations
|
||||
**Priority:** MEDIUM
|
||||
**Status:** PENDING
|
||||
**Added:** 2026-05-09 by Neo
|
||||
|
||||
**Description:**
|
||||
No way to rollback or recover from failed migrations without manual database repairs.
|
||||
|
||||
**Rationale:**
|
||||
- If a migration fails, no automatic recovery
|
||||
- Admin must manually fix database state
|
||||
- No rollback scripts to revert breaking changes
|
||||
- Risk: extended downtime on production
|
||||
|
||||
**Implementation Notes:**
|
||||
- Design migrations with rollback functions
|
||||
- Store rollback SQL alongside migration
|
||||
- Implement `ROLLBACK_LAST_MIGRATION` functionality
|
||||
- Document manual recovery procedures

||||
### ~~No Rollback Capability for Failed Migrations~~ ✅ COMPLETED (v0.23.1)

# Bill Tracker — Changelog
|
||||
|
||||
## v0.23.1
|
||||
|
||||
### Added
|
||||
- **Migration Rollback** — New `rollbackMigration()` function in database.js and `POST /api/admin/migrations/rollback` endpoint for admin-only migration rollback
|
||||
- Rollback support for v0.44 (performance indexes), v0.45 (audit_log table), v0.46 (cycle columns)
|
||||
- Transaction-wrapped rollback with detailed logging (`[rollback]`, `[rollback-error]`)
|
||||
- Audit logging for rollback events: `migration.rollback` and `migration.rollback.failure`
|
||||
- Error codes: `NOT_APPLIED` (404), `ROLLBACK_NOT_SUPPORTED` (422)
|
||||
|
||||
### Fixed
|
||||
- **Duplicate migrationStartTime declaration** — Removed duplicate variable declaration causing syntax error
|
||||
- **Duplicate else block** — Removed duplicated migration skip branch in `runMigrations()`
|
||||
- **DB path exposure** — Changed `Opening DB at:` log to use `path.basename()` instead of full path
|
||||
|
||||
### Changed
|
||||
- `routes/admin.js`: Added `rollbackMigration` import and `/migrations/rollback` endpoint
|
||||
- `db/database.js`: Added `rollbackMigration()` function with transaction support and rollback SQL map

**Status:** Complete
|
||||
**Last Updated:** 2026-05-10
|
||||
**Owner:** Bishop
|
||||

## Version 0.23.1 Update
|
||||
|
||||
### Migration Rollback Feature (2026-05-10)
|
||||
|
||||
**Added:** Database migration rollback capability with transaction support, rollback SQL definitions, and admin API endpoint.
|
||||
|
||||
**Files Modified:**
|
||||
- `db/database.js` — Added `rollbackMigration()` function, `ROLLBACK_SQLS` map, `hasRollbackSQL()`, `getRollbackSQL()`
|
||||
- `routes/admin.js` — Added `POST /api/admin/migrations/rollback` endpoint
|
||||
- `client/lib/version.js` — Version bumped to 0.23.1 with rollback highlights
|
||||
- `package.json` — Version bumped to 0.23.1
|
||||
|
||||
### New Functions in database.js
|
||||
|
||||
**File:** `db/database.js`
|
||||
|
||||
#### RollbackSQLS Map
|
||||
|
||||
```javascript
|
||||
const ROLLBACK_SQLS = {
|
||||
'v0.44': [
|
||||
'DROP INDEX IF EXISTS idx_bills_due_date',
|
||||
'DROP INDEX IF EXISTS idx_payments_bill_id',
|
||||
'DROP INDEX IF EXISTS idx_users_email',
|
||||
],
|
||||
'v0.45': [
|
||||
'DROP TABLE IF EXISTS audit_log',
|
||||
],
|
||||
'v0.46': [
|
||||
'ALTER TABLE bills DROP COLUMN cycle_start_day',
|
||||
'ALTER TABLE bills DROP COLUMN cycle_end_day',
|
||||
],
|
||||
};
|
||||
```
|
||||
|
||||
#### rollbackMigration(version) Function
|
||||
|
||||
**Signature:** `rollbackMigration(version: string) => { success: boolean, error?: string, message?: string }`
|
||||
|
||||
**Description:** Rolls back a previously applied migration by executing its rollback SQL statements within a transaction.
|
||||
|
||||
**Error Codes:**
|
||||
- `NOT_APPLIED` (404): Migration hasn't been applied to the database
|
||||
- `ROLLBACK_NOT_SUPPORTED` (422): No rollback SQL defined for this migration version
|
||||
- `NO_ROLLBACK_STATEMENTS`: Migration has empty rollback SQL array
|
||||
|
||||
**Audit Events:**
|
||||
- `migration.rollback`: Successful rollback with statement count
|
||||
- `migration.rollback_failure`: Failed rollback with error details
|
||||
|
||||
**Security:** Admin-only endpoint via `requireAuth` + `requireAdmin` middleware
|
||||
|
||||
### API Endpoint
|
||||
|
||||
**Endpoint:** `POST /api/admin/migrations/rollback`
|
||||
|
||||
**Authentication:** Admin-only (`requireAuth` + `requireAdmin`)
|
||||
|
||||
**Request Body:**
|
||||
```json
|
||||
{
|
||||
"version": "v0.46"
|
||||
}
|
||||
```
|
||||
|
||||
**Success Response (200):**
|
||||
```json
|
||||
{
|
||||
"success": true,
|
||||
"version": "v0.46",
|
||||
"statements": 2
|
||||
}
|
||||
```
|
||||
|
||||
**Error Responses:**
|
||||
|
||||
**NOT_APPLIED (404):**
|
||||
```json
|
||||
{
|
||||
"success": false,
|
||||
"error": "NOT_APPLIED",
|
||||
"message": "Migration v0.46 has not been applied"
|
||||
}
|
||||
```
|
||||
|
||||
**ROLLBACK_NOT_SUPPORTED (422):**
|
||||
```json
|
||||
{
|
||||
"success": false,
|
||||
"error": "ROLLBACK_NOT_SUPPORTED",
|
||||
"message": "Rollback not supported for migration v0.40"
|
||||
}
|
||||
```
|
||||
|
||||
### Supported Rollback Versions
|
||||
|
||||
| Version | Description | Rollback SQL | Risk Level |
|
||||
|---------|-------------|--------------|------------|
|
||||
| v0.44 | Performance indexes | Drop 3 indexes | LOW - Indexes can be recreated |
|
||||
| v0.45 | Audit log table | Drop table | MEDIUM - Data loss, but low-impact table |
|
||||
| v0.46 | Cycle tracking columns | Drop 2 columns | LOW - Column data lost, but recoverable |
|
||||
|
||||
### Testing Rollback
|
||||
|
||||
**Docker Test:**
|
||||
```bash
|
||||
docker exec bill-tracker node -e "
|
||||
const {getDb,rollbackMigration}=require('./db/database');
|
||||
getDb();
|
||||
console.log(JSON.stringify(rollbackMigration('v0.46')));
|
||||
"
|
||||
```
|
||||
|
||||
**Expected Output (v0.46 success):**
|
||||
```json
|
||||
{
|
||||
"success": true,
|
||||
"version": "v0.46",
|
||||
"statements": 2
|
||||
}
|
||||
```
|
||||
|
||||
**Expected Output (v0.40 - no rollback):**
|
||||
```json
|
||||
{
|
||||
"success": false,
|
||||
"error": "ROLLBACK_NOT_SUPPORTED",
|
||||
"message": "Rollback not supported for migration v0.40"
|
||||
}

||||
