-For complicated tasks involving multiple components or phases, always use todo lists to track progress: - -1. **When to Create a Todo List**: - - Multi-file changes spanning different modules - - Implementation of design documents with multiple phases - - Bug fixes requiring investigation across components - - Any task with 3+ distinct steps - -2. **Todo List Structure**: - - Group items by logical phases or components - - Use `===` prefix for phase headers (e.g., `=== Phase 1: Foundation ===`) - - Mark status: `completed`, `in_progress`, or `pending` - - Only one item should be `in_progress` at a time - -3. **Maintaining the Todo List**: - - Update status immediately when completing a task - - Add new items discovered during implementation - - Remove items that become irrelevant - - Keep the list visible to track overall progress - -4. **Example Todo List for Multi-Phase Implementation**: - ``` - === Phase 1: Core Infrastructure === - [completed] Create base types and traits - [completed] Implement worker abstraction - [in_progress] Add progress tracking - - === Phase 2: Integration === - [pending] Wire up to existing API - [pending] Add SQL command support - - === Testing === - [pending] Unit tests - [pending] Integration tests - ``` - -### Debug Scripts - -**RULE: All debug/diagnostic scripts go in `src/bin/`, not inline Python/bash scripts.** - -When investigating issues or creating diagnostic tools: -- Create proper Rust binaries in `src/bin/*.rs` -- Use descriptive names: `check_*.rs`, `debug_*.rs`, `diagnose_*.rs` -- Build and run with `cargo run --bin ` or `cargo build --bin ` -- This ensures debug tools are version-controlled, type-checked, and reusable - -**Examples**: -- `src/bin/mcap_info.rs` - Dump MCAP file info -- `src/bin/debug_schema.rs` - Examine schema parsing -- `src/bin/check_bag.rs` - Verify BAG file structure - -**When to create debug scripts**: -- Inspecting MCAP/BAG file contents -- Verifying schema transformations -- Tracing decoder behavior -- Any investigation that benefits from a reusable tool -

Update version parsing regex to accept HDF5 2.x versions - Add cfg flags emission for 2.0.x versions - Update Homebrew search to include HDF5 2.0 Versioned API Bindings: - H5Dread_chunk2 (with new buf_size parameter) - H5Tdecode2 (with new buf_size parameter) - H5Iregister_type2 (hash_size parameter removed) - Deprecated v1 APIs still available for backward compatibility New HDF5 2.0 Types: - H5T_COMPLEX datatype class - Complex number predefined types (H5T_COMPLEX_IEEE_F32LE, etc.) - bfloat16 predefined types (H5T_FLOAT_BFLOAT16LE/BE) - FP8 predefined types (H5T_FLOAT_F8E4M3, H5T_FLOAT_F8E5M2) - H5Tcomplex_create function binding High-Level API: - Add is_complex() method on Datatype (HDF5 2.0.0+) - Handle H5T_COMPLEX class in to_descriptor() Tests: - Comprehensive test suite for HDF5 2.0.0 features - Tests conditionally compiled based on HDF5 version -
