During June 2026, this developer delivered a feature for the google/perfetto repository that enables visualization of OutOfMemoryError callstacks within the Perfetto UI. Using TypeScript and C++, they implemented new UI components and data queries, allowing developers to inspect memory-related errors directly in both the Timeline and Heap Dump Explorer views. This addition streamlines the memory debugging workflow by making OOM scenarios more visible and reducing the time required for diagnosis. The work focused on integrating callstack data into the existing interface, enhancing the overall reliability and performance of memory issue analysis without introducing major bug fixes during the period.
