Worked on the curl/curl repository to address a debugging issue in OS400 builds by implementing a targeted shell script fix. Focused on build automation and debugging, the solution preserved temporary source files during debug builds, ensuring that the debugger retained access to necessary artifacts for troubleshooting. By preventing the premature deletion of these files, the change reduced downtime for developers and improved the reliability of the debug process. The update was carefully scoped to minimize disruption to existing workflows, using shell scripting to maintain build integrity while supporting more effective debugging and maintenance for the OS400 environment within the curl/curl project.
