December 2025 — mozilla/glean: Key reliability, testing, and safety enhancements for the PingUploadScheduler, along with concurrency fixes for Dispatchers. Implemented dependency injection to decouple PingUploadScheduler, added unit tests and mock types, clarified safety constraints for app extensions, and fixed a loop-exit bug in task execution. Resolved concurrency warnings by making Dispatchers' closures Sendable, enabling safe parallel execution. These changes improve data upload reliability, reduce risk in restricted environments, and provide stronger test coverage for future changes.

May 2025 highlights across two core repos (mozilla/probe-scraper and mozilla/glean) focused on reliability, data integrity, and developer productivity for iOS data collection. Key features delivered: - mozilla/glean: iOS SDK Generator now supports Xcode input file lists (.xcfilelist) and improved input file reading and YAML discovery display for robustness and clarity. Major bugs fixed: - mozilla/probe-scraper: Corrected config paths after Firefox iOS refactor, updating metrics/pings/tags YAML file paths to reference the new Glean subdirectory (commit 3e197218fac94ca997e85726a4ce2e3176908226). Overall impact and accomplishments: - Restored and hardened iOS data collection references, reducing breakage after refactors and improving YAML discovery visibility, which lowers debugging time and supports reliable metrics ingestion. Technologies/skills demonstrated: - Shell scripting robustness, YAML handling, Xcode/.xcfilelist processing, code quality improvements (shellcheck), and cross-repo collaboration.
