Worked on the llvm/clangir repository to address a critical issue in the LLDB DAP tool, focusing on improving debugger reliability for end users. Using C++ and leveraging strong debugging skills, corrected the disconnect handling logic by updating the conditional check from req->arguments to req->command. This change ensured that disconnect requests were properly recognized and processed, resolving a scenario where the disconnect path could not be triggered due to the previous condition. The fix, implemented in July 2025, led to more stable LLDB DAP sessions and reduced user-reported disconnect failures, directly enhancing the overall debugging workflow and support experience.
