Worked on the google/perfetto repository to enhance post-mortem debugging by implementing OutOfMemoryError (OOME) metadata capture and heap dump processing within the Trace Processor. Leveraged C++ and SQL to introduce new database tables for persisting heap dump details, including allocation sizes and error messages, and integrated OOME data into the existing ingestion pipeline. Improved stack trace deobfuscation for OOME events by extending the DeobfuscationTracker, supporting more accurate package identification and ProGuard deobfuscation. Also addressed a proto_merger issue by refining the merging logic to eliminate duplicate warning comments, resulting in cleaner merged outputs and more reliable code maintenance.
