PROFILE
David Reveman
Contributed to the google/perfetto repository by developing and refining Rust SDK features, GPU tracing capabilities, and trace processing flexibility. Focused on enhancing trace data reliability and configurability, the work included implementing out-of-order trace packet handling, expanding GPU event tracking, and improving dependency management for reproducible builds. Leveraged Rust, C++, and Protocol Buffers to deliver new API surfaces, cross-platform compatibility, and automated publishing workflows. Addressed bugs in dependency resolution and Rust bindings, while strengthening CI/CD integration and documentation. The engineering approach emphasized maintainability, robust testing, and alignment with open source governance, resulting in more flexible and reliable tracing infrastructure.

Dec 1, 2025December 2025 monthly summary for google/perfetto focusing on key features delivered, major fixes, and outcomes. Key value delivered includes improved observability and tracing configurability across GPU and Rust SDK components, enabling faster diagnostics and more precise performance tuning for GPU workloads and distributed tracing scenarios. The work progressed core capabilities and testing coverage to ensure reliability in production. Highlights: - GPU Event Tracking Enhancement: include gpu_id in gpu_counter_track to enable precise GPU performance metric tracking; updated GPU event parser and tests to verify the new parameter. - Rust SDK Tracing Enhancements: introduced TracePacketSequenceFlags enum and trace_all_machines field in TraceConfig to provide finer-grained control over trace sequences and configurations; updated core proto bindings and manually generated trace_packet bindings to reflect the new API.

Nov 1, 2025November 2025 (google/perfetto) — Focused on strengthening GPU tracing, deterministic publish workflows, and SDK usability. Delivered new GPU protobuf bindings, refined local dependency versioning, and expanded API/UX surfaces to support broader adoption. This combination enables richer GPU trace data, smoother integration into CI/CD pipelines, and a more intuitive developer experience. Notable reliability improvements and CI checks contributed to more stable releases. Key features delivered: - GPU Protobuf Bindings: Added perfetto-protos-gpu crate to provide extra protobuf bindings for GPU events, enabling richer GPU trace data for performance analysis. - Local Dependency Versioning: Cargo/local dependencies now include explicit version references to improve reproducibility and publishability. - SDK API/UX Improvements: Implemented data source callback args and added missing API surfaces, plus a code clarity refactor (replacing a single-case match with an if statement). - Command-line UX: perfetto_cmd now supports --notify-fd to wait for all data sources to be started, improving capture reliability. - Publishing Hygiene: Renamed crates for crates.io publishing and completed cargo fixes to prepare crates for publishing (including homepage entries and lockfile updates). Major bugs fixed: - Typo in Rust bindings causing patch errors has been fixed, improving patch application reliability and CI stability. Overall impact and accomplishments: - Enabled richer, more reliable GPU tracing data and smoother, more deterministic publishing workflows, accelerating onboarding for consumers and reducing integration risk. The SDK is now more ergonomic with API improvements and better data source handling, contributing to faster feature delivery and release cycles. Technologies/skills demonstrated: - Rust SDK development, Cargo publishing workflows, crates.io packaging, syn v2 upgrade, vendored feature wiring, CI/automation checks, and clang-based shared library building.

Feb 1, 2025February 2025: Focused on enhancing trace processing flexibility in google/perfetto. Delivered Flexible Trace Processing with Out-of-Order Clock Snapshots, allowing deferral of packets missing clock snapshots and enabling a full sorting mode to ensure correct processing once snapshots arrive. This work, committed in d5ff035769e88cc50894b8c80e7a2ca671f7fa48, improves resilience to out-of-order clock references and broadens usable scenarios for trace data. While no major bugs were fixed in this period, the change simplifies correctness guarantees and reduces the need for strict in-order clock snapshot emission, delivering business value by making Perfetto more robust and flexible in real-world tracing workloads. Demonstrates design excellence (out-of-order processing, deferred work), code quality, and collaboration across the repository.
