feat: add SQLite database corruption guardrails
- Add PRAGMA quick_check on startup with warning log if corrupted - Add corruption sentinel helpers for structured error detection - Add backup retention (keep last 7, auto-cleanup after daily backup) - Add GET /api/v1/health/db endpoint for orchestrator health checks Prevents silent data loss and enables proactive corruption detection.

# Database Corruption Guardrails Implementation Plan
|
||||
|
||||
**Status:** 📋 Planning
|
||||
**Date:** 2024-12-17
|
||||
**Priority:** High
|
||||
**Epic:** Database Resilience
|
||||
|
||||
## Overview
|
||||
|
||||
This plan implements proactive guardrails to detect, prevent, and recover from SQLite database corruption. The implementation builds on existing patterns in the codebase and integrates with the current backup infrastructure.
|
||||
|
||||
---
|
||||
|
||||
## 1. Startup Integrity Check
|
||||
|
||||
**Location:** `backend/internal/database/database.go`
|
||||
|
||||
### Design
|
||||
|
||||
Add `PRAGMA quick_check` after database connection is established. This is a faster variant of `integrity_check` suitable for startup—it verifies B-tree page structure without checking row data.
|
||||
|
||||
### Implementation
|
||||
|
||||
#### Modify `Connect()` function in `database.go`
|
||||
|
||||
```go
|
||||
// After line 53 (after WAL mode verification):
|
||||
|
||||
// Run quick integrity check on startup
|
||||
var integrityResult string
|
||||
if err := db.Raw("PRAGMA quick_check").Scan(&integrityResult).Error; err != nil {
|
||||
logger.Log().WithError(err).Error("Failed to run database integrity check")
|
||||
} else if integrityResult != "ok" {
|
||||
logger.Log().WithFields(logrus.Fields{
|
||||
"result": integrityResult,
|
||||
"database": dbPath,
|
||||
"action": "startup_integrity_check",
|
||||
"severity": "critical",
|
||||
}).Error("⚠️ DATABASE CORRUPTION DETECTED - Run db-recovery.sh to repair")
|
||||
} else {
|
||||
logger.Log().Info("Database integrity check passed")
|
||||
}
|
||||
```
|
||||
|
||||
### Behavior
|
||||
|
||||
- **If OK:** Log info and continue normally
|
||||
- **If NOT OK:** Log critical error with structured fields, DO NOT block startup
|
||||
- **Error running check:** Log warning, continue startup
|
||||
|
||||
### Test Requirements
|
||||
|
||||
Create `backend/internal/database/database_test.go`:
|
||||
|
||||
```go
|
||||
func TestConnect_IntegrityCheckLogged(t *testing.T) {
|
||||
// Test that integrity check is performed on valid DB
|
||||
}
|
||||
|
||||
func TestConnect_CorruptedDBWarnsButContinues(t *testing.T) {
|
||||
// Create intentionally corrupted DB, verify warning logged but startup succeeds
|
||||
}
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 2. Corruption Sentinel Logging
|
||||
|
||||
**Location:** `backend/internal/database/errors.go` (new file)
|
||||
|
||||
### Design
|
||||
|
||||
Create a helper that wraps database errors, detects corruption signatures, emits structured logs, and optionally triggers a one-time integrity check.
|
||||
|
||||
### New File: `backend/internal/database/errors.go`

||||

```
|
||||
|
||||
### Test Requirements
|
||||
|
||||
Create `backend/internal/database/errors_test.go`:
|
||||
|
||||
```go
|
||||
func TestIsCorruptionError(t *testing.T)
|
||||
func TestWrapDBError_DetectsCorruption(t *testing.T)
|
||||
func TestWrapDBError_NonCorruptionPassthrough(t *testing.T)
|
||||
func TestTriggerOneTimeIntegrityCheck_OnlyOnce(t *testing.T)
|
||||
```
|
||||

|
||||
|
||||
## 3. Enhanced Auto-Backup Service
|
||||
|
||||
**Location:** `backend/internal/services/backup_service.go` (existing file)
|
||||
|
||||
### Design
|
||||
|
||||
The backup service already exists with daily 3 AM scheduling. We need to:
|
||||
|
||||
1. Add configurable retention (currently no cleanup implemented in scheduled backups)
|
||||
2. Expose last backup time for health endpoint
|
||||
3. Add backup retention cleanup
|
||||
|
||||
### Modifications to `backup_service.go`
|
||||
|
||||
#### Add retention cleanup after scheduled backup
|
||||
|
||||
```go
|
||||
// Add constant at top of file
|
||||
const DefaultBackupRetention = 7
|
||||
|
||||
// Modify RunScheduledBackup():
|
||||
func (s *BackupService) RunScheduledBackup() {
|
||||
logger.Log().Info("Starting scheduled backup")
|
||||
if name, err := s.CreateBackup(); err != nil {
|
||||
logger.Log().WithError(err).Error("Scheduled backup failed")
|
||||
} else {
|
||||
logger.Log().WithField("backup", name).Info("Scheduled backup created")
|
||||
// Cleanup old backups
|
||||
s.cleanupOldBackups(DefaultBackupRetention)
|
||||
}
|
||||
}
|
||||
|
||||
// Add new method:
|
||||
func (s *BackupService) cleanupOldBackups(keep int) {
|
||||
backups, err := s.ListBackups()
|
||||
if err != nil {
|
||||
logger.Log().WithError(err).Warn("Failed to list backups for cleanup")
|
||||
return
|
||||
}
|
||||
|
||||
// Backups are already sorted newest first
|
||||
if len(backups) <= keep {
|
||||
return
|
||||
}
|
||||
|
||||
for _, backup := range backups[keep:] {
|
||||
if err := s.DeleteBackup(backup.Filename); err != nil {
|
||||
logger.Log().WithError(err).WithField("filename", backup.Filename).Warn("Failed to delete old backup")
|
||||
} else {
|
||||
logger.Log().WithField("filename", backup.Filename).Info("Deleted old backup")
|
||||
}
|
||||
}
|
||||
}
|
||||
|
||||
// Add new method for health endpoint:
|
||||
func (s *BackupService) GetLastBackupTime() (*time.Time, error) {
|
||||
backups, err := s.ListBackups()
|
||||
if err != nil {
|
||||
return nil, err
|
||||
}
|
||||
if len(backups) == 0 {
|
||||
return nil, nil
|
||||
}
|
||||
return &backups[0].Time, nil
|
||||
}
|
||||
```
|
||||
|
||||
### Test Requirements
|
||||
|
||||
Add to `backend/internal/services/backup_service_test.go`:
|
||||
|
||||
```go
|
||||
func TestCleanupOldBackups_KeepsRetentionCount(t *testing.T)
|
||||
func TestGetLastBackupTime_ReturnsNewestBackup(t *testing.T)
|
||||
func TestGetLastBackupTime_ReturnsNilWhenNoBackups(t *testing.T)
|
||||
```
|
||||
|
||||

|
||||
|
||||
## 4. Database Health Endpoint
|
||||
|
||||
**Location:** `backend/internal/api/handlers/db_health_handler.go` (new file)
|
||||
|
||||
### Design
|
||||
|
||||
Add a new endpoint `GET /api/v1/health/db` that:
|
||||
|
||||
1. Runs `PRAGMA quick_check`
|
||||
2. Returns 200 if healthy, 503 if corrupted
|
||||
3. Includes last backup time in response
|
||||
|
||||
### New File: `backend/internal/api/handlers/db_health_handler.go`
|
||||
|
||||
```go
|
||||
package handlers
|
||||
|
||||
import (
|
||||
"net/http"
|
||||
"time"
|
||||
|
||||

||||
"github.com/Wikid82/charon/backend/internal/services"
|
||||
"github.com/gin-gonic/gin"
|
||||
"gorm.io/gorm"
|
||||
)
|
||||
|
||||
// DBHealthHandler handles database health check requests
|
||||
type DBHealthHandler struct {
|
||||
db *gorm.DB
|
||||
backupService *services.BackupService
|
||||
}
|
||||
|
||||
// NewDBHealthHandler creates a new DBHealthHandler
|
||||
func NewDBHealthHandler(db *gorm.DB, backupService *services.BackupService) *DBHealthHandler {
|
||||
return &DBHealthHandler{
|
||||
db: db,
|
||||
backupService: backupService,
|
||||
}
|
||||
}
|
||||
|
||||
// DBHealthResponse represents the response from the DB health check
|
||||
type DBHealthResponse struct {
|
||||
Status string `json:"status"`
|
||||
IntegrityCheck string `json:"integrity_check"`
|
||||
LastBackupTime *string `json:"last_backup_time"`
|
||||
BackupAvailable bool `json:"backup_available"`
|
||||
}
|
||||
|
||||
// Check performs a database integrity check and returns the health status.
|
||||
// Returns 200 if healthy, 503 if corrupted.
|
||||
func (h *DBHealthHandler) Check(c *gin.Context) {
|
||||
response := DBHealthResponse{
|
||||
Status: "unknown",
|
||||
IntegrityCheck: "pending",
|
||||
LastBackupTime: nil,
|
||||
BackupAvailable: false,
|
||||
}
|
||||
|
||||
// Run quick integrity check
|
||||
var integrityResult string
|
||||
if err := h.db.Raw("PRAGMA quick_check").Scan(&integrityResult).Error; err != nil {
|
||||
response.Status = "error"
|
||||
response.IntegrityCheck = err.Error()
|
||||
c.JSON(http.StatusInternalServerError, response)
|
||||
return
|
||||
}
|
||||
|
||||
response.IntegrityCheck = integrityResult
|
||||
|
||||
// Get last backup time
|
||||
if h.backupService != nil {
|
||||
lastBackup, err := h.backupService.GetLastBackupTime()
|
||||
if err == nil && lastBackup != nil {
|
||||
formatted := lastBackup.Format(time.RFC3339)
|
||||
response.LastBackupTime = &formatted
|
||||
response.BackupAvailable = true
|
||||
}
|
||||
}
|
||||
|
||||
if integrityResult == "ok" {
|
||||
response.Status = "healthy"
|
||||
c.JSON(http.StatusOK, response)
|
||||
} else {
|
||||
response.Status = "corrupted"
|
||||
logger.Log().WithField("integrity_check", integrityResult).Warn("DB health check detected corruption")
|
||||
c.JSON(http.StatusServiceUnavailable, response)
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Route Registration in `routes.go`
|
||||
|
||||
```go
|
||||
// Add after backupService initialization (around line 110):
|
||||
dbHealthHandler := handlers.NewDBHealthHandler(db, backupService)
|
||||
|
||||
// Add before api := router.Group("/api/v1") (around line 88):
|
||||
// Public DB health endpoint (no auth required for monitoring tools)
|
||||
router.GET("/api/v1/health/db", dbHealthHandler.Check)
|
||||
```
|
||||
|
||||
### Test Requirements
|
||||
|
||||
Create `backend/internal/api/handlers/db_health_handler_test.go`:
|
||||
|
||||
```go
|
||||
func TestDBHealthHandler_HealthyDatabase(t *testing.T)
|
||||
func TestDBHealthHandler_CorruptedDatabase(t *testing.T)
|
||||
func TestDBHealthHandler_IncludesBackupTime(t *testing.T)
|
||||
func TestDBHealthHandler_NoBackupsAvailable(t *testing.T)
|
||||
```

|
||||
|
||||
### Service Dependencies
|
||||
|
||||
```
|
||||
routes.go
|
||||
├── database.Connect() ──→ Startup integrity check
|
||||
│ └── database.SetIntegrityCheckDB(db)
|
||||
├── services.NewBackupService()
|
||||
│ ├── CreateBackup()
|
||||
│ ├── cleanupOldBackups() [new]
|
||||
│ └── GetLastBackupTime() [new]
|
||||
└── handlers.NewDBHealthHandler(db, backupService)
|
||||
└── Check() ──→ GET /api/v1/health/db
|
||||
```
|
||||
|
||||
### Patterns to Follow
|
||||
|
||||
1. **Logging:** Use `logger.Log().WithFields()` for structured logs (see `logger.go`)
|
||||
2. **Error wrapping:** Use `fmt.Errorf("context: %w", err)` (see copilot-instructions.md)
|
||||
3. **Handler pattern:** Follow existing handler struct pattern (see `backup_handler.go`)
|
||||
4. **Test pattern:** Table-driven tests with `httptest` (see `health_handler_test.go`)
|
||||
|
||||
---
|
||||
|
||||
## 6. Implementation Order
|
||||
|
||||
1. **Phase 1: Detection (Low Risk)**
|
||||
- [ ] `database/errors.go` - Corruption sentinel
|
||||
- [ ] `database/database.go` - Startup check
|
||||
- [ ] Unit tests for above
|
||||
|
||||
2. **Phase 2: Visibility (Low Risk)**
|
||||
- [ ] `handlers/db_health_handler.go` - DB health endpoint
|
||||
- [ ] `routes/routes.go` - Route registration
|
||||
- [ ] Unit tests for handler
|
||||
|
||||
3. **Phase 3: Prevention (Medium Risk)**
|
||||
- [ ] `services/backup_service.go` - Retention cleanup
|
||||
- [ ] Integration tests
|
||||
|
||||

|
||||
|
||||
## 7. API Response Formats
|
||||
|
||||
### `GET /api/v1/health/db`
|
||||
|
||||
**Healthy Response (200):**
|
||||
|
||||
```json
|
||||
{
|
||||
"status": "healthy",
|
||||
"integrity_check": "ok",
|
||||
"last_backup_time": "2024-12-17T03:00:00Z",
|
||||
"backup_available": true
|
||||
}
|
||||
```
|
||||
|
||||
**Corrupted Response (503):**
|
||||
|
||||
```json
|
||||
{
|
||||
"status": "corrupted",
|
||||
"integrity_check": "*** in database main ***\nPage 123: btree page count differs",
|
||||
"last_backup_time": "2024-12-17T03:00:00Z",
|
||||
"backup_available": true
|
||||
}
|
||||
```
|
||||
|
||||
**No Backups Response (200):**
|
||||
|
||||
```json
|
||||
{
|
||||
"status": "healthy",
|
||||
"integrity_check": "ok",
|
||||
"last_backup_time": null,
|
||||
"backup_available": false
|
||||
}
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 8. Monitoring & Alerting
|
||||
|
||||
The structured logs enable external monitoring tools to detect:
|
||||
|
||||
```json
|
||||
{
|
||||
"level": "error",
|
||||
"event_type": "database_corruption",
|
||||
"severity": "critical",
|
||||
"table": "uptime_heartbeats",
|
||||
"operation": "SELECT",
|
||||
"monitor_id": "abc-123",
|
||||
"msg": "🔴 DATABASE CORRUPTION ERROR - Run scripts/db-recovery.sh"
|
||||
}
|
||||
```
|
||||
|
||||
Recommended alerts:
|
||||
|
||||
- **Critical:** Any log with `event_type: database_corruption`
|
||||
- **Warning:** `integrity_check` != "ok" at startup
|
||||
- **Info:** Backup creation success/failure

## Summary
|
||||
|
||||
This plan adds four layers of database corruption protection:
|
||||
|
||||
| Layer | Feature | Location | Risk |
|
||||
|-------|---------|----------|------|
|
||||
| 1 | Early Warning | Startup integrity check | Low |
|
||||
| 2 | Real-time Detection | Corruption sentinel logs | Low |
|
||||
| 3 | Recovery Readiness | Auto-backup with retention | Medium |
|
||||
| 4 | Visibility | Health endpoint `/api/v1/health/db` | Low |
|
||||
|
||||
All changes follow existing codebase patterns and avoid blocking critical operations.

### 11. Go Vulnerability Check
|
||||
## Issues Found & Resolved
|
||||
|
||||
**Status:** ✅ PASS
|
||||
|
||||
```text
|
||||
No vulnerabilities found.
|
||||
```
|
||||
|
||||
All Go dependencies are secure with no known CVEs.
|
||||
1. **Lint: `unnamedResult`** - Function `CheckIntegrity` now has named return values for clarity.
|
||||
2. **Lint: `equalFold`** - Used `strings.EqualFold()` instead of `strings.ToLower() == "ok"`.
|
||||
3. **Lint: `S1031`** - Removed redundant nil check before range (Go handles nil maps safely).
|
||||
4. **Lint: `httpNoBody`** - Test requests now use `http.NoBody` instead of `nil`.

### Critical Issues
|
||||
| Check | Result |
|
||||
|-------|--------|
|
||||
| Pre-commit | ✅ PASS |
|
||||
| Backend Build | ✅ PASS |
|
||||
| Backend Tests | ✅ PASS |
|
||||

|
||||
|
||||
None.
|
||||
|
||||
### Non-Critical Issues
|
||||
|
||||
1. **Version Mismatch** (Pre-commit)
|
||||
- `.version` file (0.7.13) doesn't match latest git tag (v0.9.3)
|
||||
- **Impact:** None for functionality; affects CI/CD tagging
|
||||
- **Recommendation:** Update `.version` file before next release
|
||||
|
||||
2. **ESLint Warnings** (14 total)
|
||||
- Mostly `no-explicit-any` in test files
|
||||
- **Impact:** None for production code
|
||||
- **Recommendation:** Address in future cleanup sprint
|
||||
|
||||
3. **Dockerfile Suggestion**
|
||||
- Multiple consecutive RUN instructions at line 183
|
||||
- **Impact:** Slightly larger image size
|
||||
- **Recommendation:** Consider consolidation if image size becomes a concern
