Worked on the google/perfetto repository to deliver a new configurability point for TrackEvent buffer exhaustion during tracing initialization, enhancing reliability for critical system services. Developed a configurable policy within TracingInitArgs, allowing deterministic initialization paths for applications. The technical approach involved plumbing the policy through Tracing::Initialize to TrackEvent::Register using static internal state, which clarified initialization order and reduced ambiguity. Introduced a DataSource injection pattern with a protected overload to support custom DataSourceParams, aligning with established safety patterns. Utilized C++ for system programming and performance optimization, and provided thorough documentation to support future maintainability and configurability of the codebase.
