Worked on stabilizing file input and output operations in the OpenVoxProject/puppet repository to address compatibility issues introduced by Ruby 3.2. Focused on backend development using Ruby and Ruby on Rails, implementing a targeted fix for the File.open method to ensure correct permission handling and options passing. Updated usages of FileSystem::Uniquefile to align with the new Ruby 3.2 API, and introduced regression tests to safeguard against future breakages. The work was carefully scoped, thoroughly documented, and included precise commit messages to enhance maintainability and traceability, resulting in a more robust and future-proof codebase for the project.
