Outdated 9 Year old Dependencies Solution10

[ThomasAFink]

What is Solution10 and why is it used to create queries? 8 stars on Github... 9 years no update... for PHP 5.4?

For best results, initiate chat on the files or code changes.

Let me analyze the usage of Solution10\SQL in the codebase and provide my assessment.

@ThomasAFink Based on my analysis, I have several concerns about the usage of Solution10\SQL:

1. Outdated & Unmaintained: The Solution10\SQL library hasn't been updated in 9 years and was designed for PHP 5.4, which is severely outdated and no longer supported. This poses significant security and compatibility risks.

2. Limited Community Support: With only 8 stars on GitHub and no active maintenance, there's minimal community support for bug fixes or security patches.

3. Extensive Usage: The library is used across multiple query classes in your codebase:

   • Base.php
   • Alias.php
   • Request.php
   • Provider.php
   • Queue.php
   • Useraccount.php
   • Process.php
   • ProcessStatusArchived.php
   • Availability.php

4. Better Alternatives: There are several well-maintained, modern alternatives that would be more suitable:

   • Doctrine DBAL: A robust database abstraction layer
   • Laravel Query Builder: Even if not using Laravel, the query builder can be used standalone
   • PDO with prepared statements: A native PHP solution that's secure and well-maintained

Recommendation:
I strongly recommend replacing Solution10\SQL with a modern, actively maintained query builder or ORM. This would:

1. Improve security
2. Ensure PHP 8.x compatibility
3. Provide better documentation and community support
4. Enable access to modern features and best practices

Would you like me to:

1. Open a GitHub issue to track this technical debt?
2. Provide a detailed migration plan to a specific alternative?
3. Analyze the current query patterns to suggest the most suitable replacement?

Please let me know which approach you'd prefer to tackle this dependency issue.

Tip

For best results, initiate chat on the files or code changes.

Let me analyze the current codebase structure and provide a detailed PDO refactoring approach.

@ThomasAFink Here's a comprehensive plan to refactor from Solution10\SQL to PDO with prepared statements:

1. Create a Database Configuration Class

// src/Zmsdb/Config/DatabaseConfig.php
namespace BO\Zmsdb\Config;

class DatabaseConfig
{
    public static function getDSN(): string 
    {
        return sprintf(
            "mysql:host=%s;dbname=%s;charset=utf8mb4",
            getenv('DB_HOST'),
            getenv('DB_NAME')
        );
    }

    public static function getOptions(): array 
    {
        return [
            \PDO::ATTR_ERRMODE => \PDO::ERRMODE_EXCEPTION,
            \PDO::ATTR_DEFAULT_FETCH_MODE => \PDO::FETCH_ASSOC,
            \PDO::ATTR_EMULATE_PREPARES => false,
            \PDO::MYSQL_ATTR_INIT_COMMAND => "SET NAMES utf8mb4"
        ];
    }
}

2. Create a Database Connection Manager

// src/Zmsdb/Connection/DatabaseManager.php
namespace BO\Zmsdb\Connection;

use BO\Zmsdb\Config\DatabaseConfig;

class DatabaseManager
{
    private static ?PDO $instance = null;
    
    public static function getInstance(): PDO 
    {
        if (self::$instance === null) {
            self::$instance = new PDO(
                DatabaseConfig::getDSN(),
                getenv('DB_USER'),
                getenv('DB_PASSWORD'),
                DatabaseConfig::getOptions()
            );
        }
        return self::$instance;
    }
}

3. Create a Query Builder Interface

// src/Zmsdb/Query/QueryBuilderInterface.php
namespace BO\Zmsdb\Query;

interface QueryBuilderInterface
{
    public function select(array $columns = ['*']): self;
    public function from(string $table, ?string $alias = null): self;
    public function where(string $column, string $operator, $value): self;
    public function join(string $table, string $first, string $operator, string $second): self;
    public function orderBy(string $column, string $direction = 'ASC'): self;
    public function limit(int $limit, int $offset = 0): self;
    public function getQuery(): string;
    public function getParameters(): array;
}

4. Create a Base Repository Class

// src/Zmsdb/Repository/BaseRepository.php
namespace BO\Zmsdb\Repository;

use BO\Zmsdb\Connection\DatabaseManager;

abstract class BaseRepository
{
    protected PDO $db;
    protected string $table;
    
    public function __construct()
    {
        $this->db = DatabaseManager::getInstance();
    }
    
    protected function execute(string $query, array $params = []): PDOStatement
    {
        $stmt = $this->db->prepare($query);
        $stmt->execute($params);
        return $stmt;
    }
    
    protected function fetchAll(string $query, array $params = []): array
    {
        return $this->execute($query, $params)->fetchAll();
    }
    
    protected function fetchOne(string $query, array $params = []): ?array
    {
        $result = $this->execute($query, $params)->fetch();
        return $result ?: null;
    }
    
    protected function insert(array $data): int
    {
        $columns = implode(', ', array_keys($data));
        $values = implode(', ', array_fill(0, count($data), '?'));
        
        $query = "INSERT INTO {$this->table} ($columns) VALUES ($values)";
        $this->execute($query, array_values($data));
        
        return (int)$this->db->lastInsertId();
    }
    
    protected function update(array $data, array $conditions): int
    {
        $set = implode(', ', array_map(fn($col) => "$col = ?", array_keys($data)));
        $where = implode(' AND ', array_map(fn($col) => "$col = ?", array_keys($conditions)));
        
        $query = "UPDATE {$this->table} SET $set WHERE $where";
        $stmt = $this->execute($query, [...array_values($data), ...array_values($conditions)]);
        
        return $stmt->rowCount();
    }
}

5. Example Repository Implementation (Process)

// src/Zmsdb/Repository/ProcessRepository.php
namespace BO\Zmsdb\Repository;

class ProcessRepository extends BaseRepository
{
    protected string $table = 'buerger';
    
    public function findById(int $id): ?array
    {
        $query = "
            SELECT p.*, s.name as scope_name 
            FROM buerger p
            LEFT JOIN standort s ON p.StandortID = s.StandortID
            WHERE p.BuergerID = :id
        ";
        return $this->fetchOne($query, ['id' => $id]);
    }
    
    public function findByStatus(string $status, int $scopeId): array
    {
        $query = "
            SELECT p.* 
            FROM buerger p
            WHERE p.StandortID = :scopeId
            AND CASE 
                WHEN p.Name = '(abgesagt)' THEN 'deleted'
                WHEN p.StandortID = 0 THEN 'blocked'
                WHEN p.vorlaeufigeBuchung = 1 AND p.bestaetigt = 0 THEN 'reserved'
                -- ... (rest of the status logic)
            END = :status
        ";
        return $this->fetchAll($query, [
            'scopeId' => $scopeId,
            'status' => $status
        ]);
    }
    
    public function updateStatus(int $processId, string $status): bool
    {
        $statusMap = [
            'called' => ['aufrufzeit' => date('H:i:s')],
            'processing' => ['aufruferfolgreich' => 1],
            'missed' => ['nicht_erschienen' => 1],
            // ... other status mappings
        ];
        
        if (!isset($statusMap[$status])) {
            throw new \InvalidArgumentException("Invalid status: $status");
        }
        
        return $this->update($statusMap[$status], ['BuergerID' => $processId]) > 0;
    }
}

6. Migration Strategy:

   • Create new repositories alongside existing query classes
   • Gradually migrate one query class at a time
   • Add comprehensive tests for new implementations
   • Use feature flags to switch between implementations
   • Remove old Solution10 code once verified

7. Example Usage:

// Example service class
class ProcessService
{
    private ProcessRepository $repository;
    
    public function __construct(ProcessRepository $repository)
    {
        $this->repository = $repository;
    }
    
    public function getProcessDetails(int $processId): array
    {
        $process = $this->repository->findById($processId);
        if (!$process) {
            throw new ProcessNotFoundException($processId);
        }
        return $process;
    }
}

Benefits of this approach:

1. Type Safety: Better PHP type hinting and static analysis support
2. Security: All queries use prepared statements by default
3. Performance: Direct PDO usage without abstraction overhead
4. Maintainability: Clear separation of concerns and modern PHP patterns
5. Testability: Easy to mock repositories for unit testing

Would you like me to:

1. Open a GitHub issue to track this refactoring work?
2. Focus on a specific part of the refactoring for more details?
3. Create a migration checklist with priority order?

🔗 Analysis chain

Let me analyze the current query patterns to provide a detailed refactoring approach.

Let me analyze the query patterns and provide a concrete refactoring plan.

@ThomasAFink Here's a detailed approach to refactor from Solution10\SQL to PDO with prepared statements:

1. Create a Database Connection Class

class DatabaseConnection {
    private static ?PDO $instance = null;
    
    public static function getInstance(): PDO {
        if (self::$instance === null) {
            $dsn = "mysql:host=" . DB_HOST . ";dbname=" . DB_NAME . ";charset=utf8mb4";
            self::$instance = new PDO($dsn, DB_USER, DB_PASSWORD, [
                PDO::ATTR_ERRMODE => PDO::ERRMODE_EXCEPTION,
                PDO::ATTR_DEFAULT_FETCH_MODE => PDO::FETCH_ASSOC,
                PDO::ATTR_EMULATE_PREPARES => false
            ]);
        }
        return self::$instance;
    }
}

2. Create a Base Query Class

abstract class BaseQuery {
    protected PDO $db;
    protected array $params = [];
    
    public function __construct() {
        $this->db = DatabaseConnection::getInstance();
    }
    
    protected function execute(string $query, array $params = []): PDOStatement {
        $stmt = $this->db->prepare($query);
        $stmt->execute($params);
        return $stmt;
    }
    
    protected function fetchAll(string $query, array $params = []): array {
        return $this->execute($query, $params)->fetchAll();
    }
    
    protected function fetchOne(string $query, array $params = []): ?array {
        $result = $this->execute($query, $params)->fetch();
        return $result !== false ? $result : null;
    }
}

3. Refactor Individual Query Classes
   Example refactoring of a query class:

class UserQuery extends BaseQuery {
    public function findById(int $id): ?array {
        $query = "SELECT * FROM users WHERE id = :id";
        return $this->fetchOne($query, ['id' => $id]);
    }
    
    public function findByEmail(string $email): ?array {
        $query = "SELECT * FROM users WHERE email = :email";
        return $this->fetchOne($query, ['email' => $email]);
    }
    
    public function create(array $data): int {
        $query = "INSERT INTO users (name, email) VALUES (:name, :email)";
        $this->execute($query, [
            'name' => $data['name'],
            'email' => $data['email']
        ]);
        return (int)$this->db->lastInsertId();
    }
}

4. Migration Strategy:

   • Create new PDO-based classes alongside existing ones
   • Gradually migrate one query class at a time
   • Use feature flags to switch between old and new implementations
   • Add comprehensive tests for new implementations
   • Once verified, remove old Solution10 implementations

5. Testing Approach:

class UserQueryTest extends TestCase {
    private UserQuery $query;
    
    protected function setUp(): void {
        $this->query = new UserQuery();
    }
    
    public function testFindById(): void {
        $user = $this->query->findById(1);
        $this->assertIsArray($user);
        $this->assertArrayHasKey('id', $user);
    }
}

Benefits of this approach:

1. Security: All queries are automatically prepared statements
2. Type Safety: Better PHP type hinting support
3. Performance: Direct PDO usage without abstraction overhead
4. Maintainability: Simple, modern PHP patterns
5. Testability: Easy to mock and test

Would you like me to:

1. Open a GitHub issue to track this refactoring work?
2. Provide more specific examples for any particular query patterns you're using?
3. Create a detailed migration checklist?

@ThomasAFink Based on the code analysis, here's a visual overview of how Solution10\SQL is used in the codebase:

classDiagram
    class Solution10SQL {
        +Select
        +Insert
        +Update
        +Delete
        +Expression
        +ConditionBuilder
    }

    class Base {
        +query: Solution10\SQL\Query
        +prefix: string
        +name: string
        +resolveLevel: int
        +__construct()
        +addSelect()
        +addTable()
        +leftJoin()
        +getSql()
        +getParameters()
        #expression()
    }

    Base --> Solution10SQL : uses

    class Process
    class Queue
    class ProcessStatusArchived
    class Provider
    class Request
    class Useraccount

    Base <|-- Process
    Base <|-- Queue
    Base <|-- ProcessStatusArchived 
    Base <|-- Provider
    Base <|-- Request
    Base <|-- Useraccount

    note for Base "Abstract base class that\nhandles SQL operations"
    note for Solution10SQL "External query builder\nlibrary"

Loading

Key usage patterns:

1. Query Building

   • The Base class acts as a wrapper around Solution10\SQL
   • Handles SELECT, INSERT, UPDATE, DELETE operations
   • Manages table aliases and joins
   • Provides expression building

2. Common Operations:

   // Condition building
   $this->query->where('field', '=', 'value');
   
   // Complex conditions
   $this->query->where(function (\Solution10\SQL\ConditionBuilder $query) {
       $query->andWith('field1', '=', 'value1');
       $query->orWith('field2', 'LIKE', '%value2%');
   });
   
   // Joins
   $this->leftJoin(
       new Alias('table', 'alias'),
       'field1',
       '=',
       'field2'
   );

3. Entity Mapping

   • Each entity class (Process, Queue, etc.) defines its own mapping
   • Maps database fields to entity properties
   • Handles complex expressions and conditions

4. Query Types Used:

   • SELECT: For fetching records
   • INSERT: For creating new records
   • UPDATE: For modifying existing records
   • DELETE: For removing records
   • REPLACE: For upsert operations

This architecture makes Solution10\SQL deeply integrated into the codebase's data access layer, which explains why replacing it would require significant refactoring. Would you like me to provide a detailed migration plan to PDO with prepared statements?

🔗 Analysis chain

Let me gather information about how Solution10\SQL is used in the codebase.

Let me analyze the results and create a visual overview.

@ThomasAFink Here's a visual overview of how Solution10\SQL is used in the codebase:

classDiagram
    class Base {
        +select()
        +insert()
        +update()
        +delete()
        #buildQuery()
        #executeQuery()
    }
    class Solution10SQL {
        +select()
        +insert()
        +update()
        +delete()
        +where()
        +join()
    }
    Base --> Solution10SQL : uses

    Base <|-- Alias
    Base <|-- Request
    Base <|-- Provider
    Base <|-- Queue
    Base <|-- Useraccount
    Base <|-- Process
    Base <|-- ProcessStatusArchived
    Base <|-- Availability

    note for Base "Abstract base class that\nwraps Solution10\SQL\noperations"
    note for Solution10SQL "External library for\nSQL query building"

Loading

The architecture follows a pattern where:

1. Base.php acts as an abstract base class that wraps Solution10\SQL functionality
2. All query classes inherit from Base and utilize its methods for:
   • SELECT operations
   • INSERT operations
   • UPDATE operations
   • DELETE operations
   • Complex WHERE conditions
   • JOIN operations

This design makes it relatively straightforward to replace Solution10\SQL with PDO prepared statements, as we can:

1. Keep the same class hierarchy
2. Replace the Solution10\SQL query building in the Base class with PDO
3. Maintain the same public API for all child classes

Would you like me to provide a concrete example of how to refactor one of these query classes to use PDO with prepared statements?
