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 resolves a potential thread-safety concern by isolating a static variable to individual threads. By making cur_cmd_cmnt thread-local, the change guarantees that concurrent operations will not interfere with each other's state, thereby enhancing the stability and correctness of the tokenizer in multi-threaded contexts.

Highlights

  • Thread-Safety Fix: The cur_cmd_cmnt static variable in lib/c_tokenizer.cpp has been updated to use the thread_local specifier, ensuring that each thread has its own instance of this variable and preventing potential race conditions in multi-threaded environments.

Code Review

This pull request addresses a critical thread-safety issue by declaring the global variable cur_cmd_cmnt as thread_local. This change correctly prevents a race condition that could occur when multiple threads concurrently execute the query tokenization logic, which uses this buffer. Each thread will now have its own private copy of cur_cmd_cmnt, ensuring data integrity. The fix is accurate and essential for a multi-threaded environment.
