Summary of Changes

Hello @tatsuhiro-t, 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 refines the urlparse.c module by applying the const qualifier to various static lookup tables. This modification ensures that these data structures, which are integral to URL parsing, remain immutable throughout the program's execution. The primary benefits include improved code robustness and potential performance gains through compiler optimizations.

Highlights

• Immutability: Several static lookup tables within urlparse.c have been explicitly marked as const, indicating they are read-only.
• Code Safety and Optimization: This change enhances code safety by preventing unintended modifications to these critical parsing tables and allows for potential compiler optimizations, such as placing them in read-only memory.

Code Review

This pull request correctly applies the const qualifier to all lookup tables in urlparse.c. This is a good practice as it ensures these tables are not accidentally modified at runtime and allows the compiler to place them in read-only memory, which can improve code safety and may lead to optimizations. The changes are consistent and well-implemented. I have no further suggestions.
