Summary of ChangesHello @MrIbrahem, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed! This pull request enhances the robustness of the mdwiki SQL database connection by adding validation for the configuration file. It improves error handling by logging configuration issues and throwing a RuntimeException when necessary. A new unit test ensures that missing configuration scenarios are properly handled.

Code Review
This pull request effectively addresses a potential runtime failure by adding validation for the mdwiki database configuration file. The approach of logging detailed errors for operators while throwing a generic exception to callers is sound. The inclusion of a PHPUnit test to cover the missing configuration scenario is a valuable addition. My review includes a few suggestions to further improve code quality and adhere to PHP best practices, such as avoiding the error suppression operator and simplifying a conditional check.

Using the error suppression operator (@) is generally discouraged as it can hide important warnings (e.g., if the file is unreadable due to permissions) and make debugging more difficult. It's better practice to explicitly check for the file's existence and readability using is_readable() before attempting to parse it.

The !is_array($ts_mycnf) check is redundant. According to the PHP documentation, parse_ini_file returns false on any failure (including file not found when @ is used) and an array on success (which can be empty). A strict check for false is sufficient and makes the code cleaner.

To reliably unset an environment variable, you should pass an empty string as the value. The behavior of putenv() with only the variable name is not guaranteed across all systems and PHP versions for unsetting. The documented way is to use putenv('VAR=').

The use of the error suppression operator (@) on lines 65 and 69 can hide issues during test cleanup (e.g., permission errors), potentially leaving artifacts that could interfere with other tests. It's generally better to avoid error suppression to make debugging easier and test environments cleaner.
