From 991d22d5f932e3ba04deba9013847c04d8158e3f Mon Sep 17 00:00:00 2001 From: Zhexuan Yang Date: Sat, 7 Feb 2026 09:45:08 +0800 Subject: [PATCH 01/21] refactor(mcap): integrate mcap crate for S3 streaming Integrate Foxglove's mcap crate for MCAP parsing while keeping robocodec's custom Rayon-based parallel decompression for 6-8x performance on local files. Changes: - Add McapS3Adapter wrapping mcap::LinearReader for S3 streaming - Replace StreamingMcapParser with McapS3Adapter in S3Reader - Deprecate StreamingMcapParser (use McapS3Adapter instead) - Make s3_adapter crate-private (not part of public API) - Fix silent failures: add logging for MCAP parse errors This reduces custom MCAP parsing code from ~1600 lines to ~460 lines while maintaining parallel decompression performance. --- src/io/formats/mcap/mod.rs | 9 +- src/io/formats/mcap/s3_adapter.rs | 435 ++++++++++++++++++++++++++++++ src/io/formats/mcap/stream.rs | 7 + src/io/s3/reader.rs | 304 +++++++++++---------- 4 files changed, 612 insertions(+), 143 deletions(-) create mode 100644 src/io/formats/mcap/s3_adapter.rs diff --git a/src/io/formats/mcap/mod.rs b/src/io/formats/mcap/mod.rs index 7f05107..4478b7e 100644 --- a/src/io/formats/mcap/mod.rs +++ b/src/io/formats/mcap/mod.rs @@ -7,11 +7,12 @@ //!

Add Transport trait with poll-based async I/O - Implement LocalTransport, S3Transport, HttpTransport, MemoryTransport - Add TransportExt with convenience methods (read, seek, read_to_end) **Streaming Parser Unification:** - Consolidate StreamingParser trait in io/streaming/parser.rs - Add Clone + Send bounds to Message associated type - All formats implement StreamingParser (MCAP, BAG, RRD) **Format Readers:** - Add open_from_transport() method to FormatReader trait - Add McapTransportReader for transport-based MCAP reading - Add RrdTransportReader for transport-based RRD reading **RoboReader Enhancements:** - Support s3:// URLs (delegates to S3Transport) - Support http:// and https:// URLs (delegates to HttpTransport) - Unified path/URL parsing with automatic transport selection **Bug Fixes:** - Fix BAG StreamingParser infinite recursion (use fully qualified syntax) - Remove duplicate s3/parser.rs (consolidated to io/streaming/parser.rs) - Fix duplicate #[test] attribute in reader/mod.rs **New Files:** - src/io/streaming/ - Unified streaming parser module - src/io/transport/transport.rs - Core Transport trait - src/io/transport/http/ - HTTP transport implementation - src/io/transport/memory/ - In-memory transport for testing - src/io/formats/mcap/streaming.rs - Unified MCAP streaming parser - src/io/formats/mcap/transport_reader.rs -

- -To add a new format (e.g., ROS2 bag): - -1. **Create format module**: `src/io/formats/ros2bag/` -2. **Implement traits**: - - `FormatReader` trait for reading - - `FormatWriter` trait for writing - - `FormatRewriter` trait for rewriting (in `rewriter/ros2bag.rs`) -3. **Add low-level I/O**: `reader.rs`, `writer.rs` with parallel/sequential strategies -4. **Update format detection**: Add extension to `io/detection.rs` -5. **Update rewriter facade**: Add format handling to `rewriter/facade.rs` -6. **Export module**: Add to `io/formats/mod.rs` and `lib.rs` - ## Related Documentation -

Code Quality: - Added #[must_use] to 300+ public/internal methods - Eliminated ~90 lines of code duplication in DecodedMessageIter - Fixed similar variable names (decoder vs decoded) - Added # Errors sections to 31+ Result-returning functions - Refactored downcasting to trait-based approach (DecodedMessageIterator trait) Testing Infrastructure: - Added Criterion benchmark suite (reader_bench, decoder_bench, rewriter_bench, large_file_bench) - Added 93 property-based tests with proptest - Added fuzzing infrastructure with 5 targets (mcap, bag, rrd, cdr, schema parsers) Architecture: - Separated CLI into robocodec-cli workspace member - Library no longer contains CLI dependencies (clap, indicatif, human-size) - Converted to Cargo workspace with edition 2024 Documentation: - Added comprehensive examples to public API (FormatReader, FormatWriter, TransformBuilder) - Added TECHNICAL_DEBT.md analysis and remediation plan - Added FUZZING.md documentation All 1,856 tests pass. ---
