Summary of Changes

Hello @rahim-kanji, 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 addresses and resolves compilation issues that arise when building the project with the Clang compiler. The changes specifically target how templated base classes are declared as friends within derived session classes, adapting the syntax to be compatible with Clang's stricter parsing rules. This ensures that the codebase can be successfully compiled across different compilers, enhancing its portability and maintainability.

Highlights

  • Clang Compilation Fix: Modified the friend class declarations for Base_Session in MySQL_Session.h and PgSQL_Session.h to use a templated syntax, resolving compilation errors specifically encountered with the Clang compiler.
  • Template Friend Declaration: The explicit template syntax template<typename SESS, typename DS, typename BE, typename THD> friend class Base_Session; was adopted to correctly declare Base_Session as a friend, ensuring proper parsing by Clang.

Code Review

This pull request addresses a clang compilation issue by generalizing the friend declaration for the Base_Session template class in MySQL_Session and PgSQL_Session. While this is a valid fix, it is overly permissive as it grants friendship to all instantiations of Base_Session. I have suggested a more constrained and readable alternative using a using alias for the specific base class specialization. This approach should also resolve the compilation error while better preserving encapsulation.
