||||
|
||||
## 🚨 CRITICAL ISSUES (Must Fix)
|
||||
|
||||
### 1. PHP Version Check Inconsistencies
|
||||
|
||||
#### File: `desk_moloni.php:34-35`
|
||||
```php
|
||||
// CURRENT (PROBLEMATIC)
|
||||
if (version_compare(PHP_VERSION, '8.0.0', '<')) {
|
||||
throw new Exception('Desk-Moloni v3.0 requires PHP 8.0 or higher. Current version: ' . PHP_VERSION);
|
||||
}
|
||||
|
||||
// FIX REQUIRED
|
||||
if (version_compare(PHP_VERSION, '8.4.0', '<')) {
|
||||
throw new Exception('Desk-Moloni v3.0 requires PHP 8.4 or higher. Current version: ' . PHP_VERSION);
|
||||
}
|
||||
```
|
||||
|
||||
#### File: `modules/desk_moloni/config/config.php:21`
|
||||
```php
|
||||
// CURRENT (PROBLEMATIC)
|
||||
define('APP_MINIMUM_REQUIRED_PHP_VERSION', '7.4.0');
|
||||
|
||||
// FIX REQUIRED
|
||||
define('APP_MINIMUM_REQUIRED_PHP_VERSION', '8.4.0');
|
||||
```
|
||||
|
||||
#### File: `modules/desk_moloni/config/config.php:42`
|
||||
```php
|
||||
// CURRENT (PROBLEMATIC)
|
||||
'requires_php_version' => '8.0.0',
|
||||
|
||||
// FIX REQUIRED
|
||||
'requires_php_version' => '8.4.0',
|
||||
```
|
||||
|
||||
### 2. PHPUnit Schema Version
|
||||
|
||||
#### File: `phpunit.xml:3`
|
||||
```xml
|
||||
<!-- CURRENT (PROBLEMATIC) -->
|
||||
<phpunit xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
|
||||
xsi:noNamespaceSchemaLocation="https://schema.phpunit.de/9.6/phpunit.xsd">
|
||||
|
||||
<!-- FIX REQUIRED -->
|
||||
<phpunit xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
|
||||
xsi:noNamespaceSchemaLocation="https://schema.phpunit.de/12.3/phpunit.xsd">
|
||||
```
|
||||
|
||||
### 3. Error Suppression Analysis
|
||||
|
||||
#### High-Risk Files with @ Usage:
|
||||
1. `modules/desk_moloni/views/client_portal/index.php:74` - CSS animations
|
||||
2. `scripts/security_audit.sh:267` - Error suppression detection script
|
||||
3. Various shell scripts - SSH/MySQL operations
|
||||
|
||||
**Recommended Action:** Replace with proper try-catch blocks where possible

||||
"require": {
|
||||
"php": "^8.1"
|
||||
}
|
||||
|
||||
// RECOMMENDED UPDATE
|
||||
"require": {
|
||||
"php": "^8.4"
|
||||
}
|
||||
```
|
||||
|
||||
#### File: `composer.json:10`
|
||||
```json
|
||||
// CURRENT (NEEDS UPDATE)
|
||||
"require-dev": {
|
||||
"phpunit/phpunit": "^9.6"
|
||||
}
|
||||
|
||||
// RECOMMENDED UPDATE
|
||||
"require-dev": {
|
||||
"phpunit/phpunit": "^12.3"
|
||||
}
|
||||
```
|
||||

return $this->api_timeout;
|
||||
}
|
||||
|
||||
public function setApiTimeout($timeout) {
|
||||
if ($timeout < 1 || $timeout > 300) {
|
||||
throw new InvalidArgumentException('Timeout must be between 1-300 seconds');
|
||||
}
|
||||
$this->api_timeout = $timeout;
|
||||
}
|
||||
|
||||
// POTENTIAL OPTIMIZATION with Property Hooks
|
||||
public int $apiTimeout = 30 {
|
||||
set {
|
||||
if ($value < 1 || $value > 300) {
|
||||
throw new InvalidArgumentException('Timeout must be between 1-300 seconds');
|
||||
}
|
||||
$this->apiTimeout = $value;

|
||||
public private(set) DateTime $expiresAt;
|
||||
|
||||
public function refreshToken() {
|
||||
// Only internal methods can set these values
|
||||
$this->accessToken = $newToken;
|
||||
$this->expiresAt = $newExpiration;
|
||||
}
|
||||
}

# Update config files
|
||||
sed -i "s/'7.4.0'/'8.4.0'/g" modules/desk_moloni/config/config.php
|
||||
sed -i "s/'8.0.0'/'8.4.0'/g" modules/desk_moloni/config/config.php
|
||||
|
||||
# Update composer.json
|
||||
sed -i 's/"php": "^8.1"/"php": "^8.4"/g' composer.json
|
||||
sed -i 's/"phpunit\/phpunit": "^9.6"/"phpunit\/phpunit": "^12.3"/g' composer.json
|
||||
|
||||
echo "Version updates completed!"
|
||||
```
|
||||
|
||||
### Phase 2: PHPUnit Migration (Day 3-5)

||||
<phpunit xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
|
||||
xsi:noNamespaceSchemaLocation="https://schema.phpunit.de/12.3/phpunit.xsd"
|
||||
bootstrap="tests/bootstrap.php"
|
||||
cacheDirectory="tests/.phpunit.cache"
|
||||
testdox="true"
|
||||
colors="true">
|
||||
|
||||
<!-- Keep existing test suites -->
|
||||
<testsuites>
|
||||
<testsuite name="Unit">
|
||||
<directory suffix="Test.php">tests/unit</directory>
|
||||
</testsuite>
|
||||
<!-- ... rest of configuration ... -->
|

||||
@keyframes spin {
|
||||
|
||||
// ANALYSIS: This is CSS, not PHP - NO CHANGE NEEDED ✅
|
||||
|
||||
// File: Database operations in scripts
|
||||
// CURRENT:
|
||||
$result = @mysql_query($sql);
|
||||
|
||||
// RECOMMENDED:
|
||||
try {
|
||||
$result = mysql_query($sql);
|
||||
if ($result === false) {
|
||||
throw new DatabaseException('Query failed: ' . mysql_error());
|
||||
}
|
||||
} catch (Exception $e) {
|
||||
error_log('Database error: ' . $e->getMessage());
|
||||
return false;
|
||||
}
|
||||
```
|

|
||||
{
|
||||
public function testPhpVersionRequirement()
|
||||
{
|
||||
$this->assertTrue(
|
||||
version_compare(PHP_VERSION, '8.4.0', '>='),
|
||||
'PHP 8.4+ is required'
|
||||
);
|
||||
}
|
||||
|
||||
public function testCriticalFunctionsAvailable()
|
||||
{
|
||||
$required_functions = [
|
||||
'curl_init',
|
||||
'json_encode',
|
||||
'password_hash',
|
||||
'openssl_encrypt'
|
||||
];
|
||||
|
||||
foreach ($required_functions as $function) {
|
||||
$this->assertTrue(
|
||||
function_exists($function),
|
||||
"Required function {$function} not available"
|
||||
);
|
||||
}
|
||||
}
|
||||
|
||||
public function testPhpExtensionsLoaded()
|
||||
{
|
||||
$required_extensions = [
|
||||
'curl',
|
||||
'json',
|
||||
'openssl',
|
||||
'pdo',
|
||||
'mbstring'
|
||||
];

if (version_compare(PHP_VERSION, '8.4.0', '<')) {
|
||||
throw new Exception('Desk-Moloni v3.0 requires PHP 8.4 or higher. Current version: ' . PHP_VERSION);
|
||||
}
|
||||
|
||||
// File: desk_moloni.php (Line 52)
|
||||
define('DESK_MOLONI_MIN_PHP_VERSION', '8.4.0');
|
||||
|
||||
// File: config/config.php (Line 21)
|
||||
define('APP_MINIMUM_REQUIRED_PHP_VERSION', '8.4.0');
|
||||
|
||||
// File: config/config.php (Line 42)
|
||||
'requires_php_version' => '8.4.0',
|
||||
```
|
||||
|
||||
#### 3.2 PHPUnit Configuration Update

colors="true">
|
||||
```
|
||||
|
||||
#### 3.3 Error Suppression Cleanup
|
||||
```php
|
||||
// Replace @ operators with proper error handling
|

|
||||
// NEW:
|
||||
$result = false;
|
||||
try {
|
||||
$result = file_get_contents($url);
|
||||
} catch (Throwable $e) {
|
||||
error_log("Failed to fetch URL: " . $e->getMessage());
|
||||
}
|
||||
```
|
||||
|
||||
#### 3.4 Modern PHP 8.4 Features Adoption

## 🔄 ROLLBACK EXECUTION PROCEDURES
|
||||
|
||||
### Level 1: Code-Only Rollback (5-10 minutes)
|
||||
**Use When:** Code issues, no database changes affected
|
||||
|
||||
```bash
|
||||
#!/bin/bash
|
||||
# code_rollback.sh
|
||||
|
||||
echo "🔄 Executing Code-Only Rollback..."
|
||||
|
||||
# 1. Git rollback to last stable commit
|
||||
git checkout main

||||
git log --oneline -5 # Show recent commits
|
||||
read -p "Enter commit hash to rollback to: " COMMIT_HASH
|
||||
|
||||
git reset --hard $COMMIT_HASH
|
||||
git clean -fd # Remove untracked files
|
||||
|
||||
# 2. Restore vendor dependencies
|
||||
composer install --no-dev --optimize-autoloader
|
||||
|
||||
# 3. Clear caches
|
||||
rm -rf tests/.phpunit.cache
|
||||
php -r "opcache_reset();" 2>/dev/null || true
|
||||
|
||||
# 4. Restart services
|
||||
systemctl reload apache2
|
||||
|
||||
echo "✅ Code rollback completed"
|
||||
```
|
||||
|
||||
### Level 2: Partial System Rollback (15-20 minutes)
|
||||
**Use When:** Configuration changes need reverting
|
||||
|
||||
```bash
|
||||
#!/bin/bash
|
||||
# partial_rollback.sh
|
||||
|
||||

|
||||
|
||||
# 2. Restore PHP configuration
|
||||
systemctl stop apache2
|
||||
tar -xzf "$BACKUP_DIR/config_backup.tar.gz" -C /
|
||||
|
||||
# 3. Switch PHP version back (if needed)
|
||||
a2dismod php8.4
|
||||
a2enmod php8.0
|
||||
systemctl start apache2

# 4. Verify services
|
||||
systemctl status apache2
|
||||
systemctl status mysql
|
||||
|
||||
echo "✅ Partial rollback completed"
|
||||
```
|
||||
|
||||
### Level 3: Full System Rollback (30-45 minutes)
|
||||
**Use When:** Database changes need reverting
|
||||
|
||||
```bash
|
||||
#!/bin/bash
|
||||
# full_rollback.sh

## 🛡️ ROLLBACK PREVENTION STRATEGIES
|
||||
|
||||
### Pre-Deployment Prevention
|
||||
1. **Comprehensive Testing** - Ensure all tests pass
|
||||
2. **Staging Validation** - Complete staging environment testing
|
||||
3. **Gradual Rollout** - Consider blue-green deployment
|
||||
4. **Monitoring Setup** - Comprehensive monitoring before deployment
|
||||
5. **Team Readiness** - Ensure all team members are available
|
||||
|
||||
### Early Detection Systems
|
||||
```bash
|
||||
# monitoring_setup.sh - Deploy before migration
|
||||
echo "Setting up migration monitoring..."
|
||||
|
||||
# 1. Performance monitoring
|
||||
echo "* * * * * curl -s http://localhost/desk_moloni/health_check.php || echo 'ALERT: Health check failed' | mail -s 'Migration Alert' admin@company.com" | crontab
|
||||
|
||||
# 2. Error log monitoring
|
||||
tail -f /var/log/apache2/error.log | grep -E "(FATAL|ERROR)" --line-buffered | while read line; do
|
||||
echo "MIGRATION ERROR: $line" | mail -s "Migration Error Alert" admin@company.com
|
||||
done &
|
||||
|
||||
# 3. Database monitoring
|
||||
mysql -u root -p desk_moloni -e "SELECT COUNT(*) FROM tbldeskmoloni_config" || echo "DB Alert" | mail admin@company.com

## 📚 ROLLBACK KNOWLEDGE BASE
|
||||
|
||||
### Common Issues and Solutions
|
||||
|
||||
#### Issue: "Database connection failed after rollback"
|
||||
**Solution:**
|
||||
```bash
|
||||
# Check MySQL service
|
||||
systemctl status mysql
|
||||
systemctl restart mysql
|
||||
|
||||
# Verify database exists
|
||||
mysql -u root -p -e "SHOW DATABASES;" | grep desk_moloni
|
||||
|
||||
# Test connection with application user
|
||||
mysql -u desk_moloni_user -p desk_moloni -e "SELECT 1"
|
||||
```
|
||||
|
||||
#### Issue: "PHP version mismatch after rollback"
|
||||
**Solution:**
|
||||
```bash
|
||||
# Check current PHP version
|
||||
php -v
|
||||
|
||||
# Switch PHP version
|
||||
a2dismod php8.4
|
||||
a2enmod php8.0
|
||||
systemctl restart apache2
|
||||
|
||||
# Verify correct version is active
|
||||
php -v
|
||||
```
|
||||
|
||||
#### Issue: "Composer dependencies conflict"
|
||||
**Solution:**
|
||||
```bash
|
||||
# Clear composer cache
|
||||
composer clear-cache
|
||||
|
||||
# Remove vendor directory
|
||||
rm -rf vendor/
|
||||
|
||||
# Restore from backup
|
||||
tar -xzf /backups/*/codebase_backup.tar.gz
|
