Dec 1, 2025December 2025 — OpenC3/cosmos: Key features delivered include a ScriptRunner overrides indicator with live count of active overrides and a bulk workflow UI for managing multiple microservices per plugin. Major bugs fixed: serialization hang in ScriptRunner output when processing binary data, and incorrect IO file handling in LocalMode put_target_file. These changes improve reliability, observability, and operational control, reducing downtime and boosting developer productivity. Technologies demonstrated include Vue.js UI enhancements, robust data serialization handling, and improved microservice workflow orchestration, reflecting strong cross-functional collaboration and impact on business value.

Oct 1, 2025October 2025 monthly summary for OpenC3/cosmos: Delivered a critical reliability fix in the RunningScript execution flow by correcting the Python __name__ assignment to '__main__' and aligning __file__ with the actual script filename. This ensures top-level scripts execute correctly within the RunningScript context, preventing subtle runtime errors and simplifying debugging for users leveraging the scripting engine. The fix addresses issue #2356 (commit: bfd53bcbe041e132ae03b461298ab58c9587c152). Although no new features were released this month, the change strengthens core script execution reliability, reduces production risk, and lays groundwork for broader support of top-level scripts in future releases. Emphasis was on correctness, maintainability, and clear behavior across all top-level script runs.

Sep 1, 2025OpenC3/cosmos – 2025-09 monthly summary. Focused on reliability, repeatability, and debugging visibility that drive faster delivery and lower support overhead. Key features delivered: - Stable Plugin Instance Naming System: refactored to a counter-based naming approach to avoid name collisions, improve repeatability, and maintain backward compatibility with timestamp-based names. This supports deterministic automation and easier rollbacks. Major bugs fixed: - ScriptRunner Debugger: Print Object Properties: fixed formatting to reliably print object properties by adjusting how locals are checked, improving debugging visibility during scripting tasks. - ScriptRunner Download Function: Use _get_download_url: corrected import/call flow to _get_download_url, restoring reliable file downloads. Overall impact and accomplishments: - Increased reliability of plugin naming, improved debugging experience, and restored download reliability, enabling smoother CI/CD and user operations. - Reduced debugging time and deployment risk through clearer introspection and robust download paths; preserved backward compatibility to minimize migration friction. Technologies/skills demonstrated: - Python refactoring and debugging tooling improvements; emphasis on backward compatibility and deterministic naming; collaboration evidenced by co-authored commits.
