(testing AI generation based on feeding it diffs and otherwise, generally reviewed for output)
Released: June 22, 2025
We're excited to announce rv v0.9.0, a major release that brings significant performance improvements, enhanced R-Universe support, better build logging, and more robust dependency resolution. This release focuses on making rv faster, more reliable, and easier to use in production environments.
🚀 Major Features
Incremental Library Builds
- Revolutionary Performance: Implemented incremental library builds that dramatically reduce sync times by only installing changed packages
- Smart Staging: New staging directory approach prevents unnecessary copying and linking
- Process Safety: Added sophisticated process detection to prevent removal of packages currently in use by R sessions
- Multi-library Support: Enhanced R CMD INSTALL to support multiple library paths for better dependency resolution
Enhanced R-Universe Integration
- Native API Support: Complete rewrite of R-Universe integration using their native API instead of PACKAGES files
- Improved Git Tracking: Better handling of R-Universe packages with proper git SHA tracking and subdirectory support
- Single Query Efficiency: Optimized to use single API calls instead of multiple queries per package
Build Logging and Debugging
- Comprehensive Build Logs: All package builds now generate detailed logs with stdout/stderr output
- Log Extraction: New --save-install-logs-in flag for rv sync to save build logs to a specified directory
- Better Error Diagnosis: Build failures now provide more actionable error information
🔧 Core Improvements
Dependency Resolution Enhancements
- Cyclic Dependency Handling: Completely resolved infinite loops when resolving cyclic dependencies
- Version Requirement Tracking: Fixed issues where version requirements weren't properly loaded from lockfiles
- Smarter Conflict Resolution: Improved SAT solver performance with better variable handling
System Dependencies
- Enhanced System Requirement Parsing: Better handling of system dependencies without packages
- Improved Status Reporting: More informative system dependency status in project summaries
- Better Ubuntu 20.04 Support: Fixed parsing issues with system requirements JSON
Command Line Interface
- Flexible R Version Handling: New RCommandLookup system allows soft R version requirements for planning commands
- Tree Command Improvements: Added --r-version flag to rv tree command for better flexibility
- Dependencies-Only Support: Better handling of dependencies_only packages in tree output
🛠️ Technical Improvements
Build System
- Parallel Installation: Enhanced worker threading with better debugging information
- Transactional Safety: Improved error handling to prevent corrupted library states
- Force Source Support: New example projects demonstrating force_source functionality
Cache Management
- Log Path Management: New cache methods for managing build log storage
- Better Path Resolution: Improved cache path resolution for different package sources
- Enhanced Metadata: Better tracking of package metadata and installation status
Configuration
- Extended Skip List: Added local-deps-depends-only to integration test skip list
- Environment Variable Support: New RV_NO_CHECK_OPEN_FILE environment variable for controlling file checks
- Timeout Adjustments: Increased CI timeout from 30 to 60 minutes for better reliability
🐛 Bug Fixes
- Fixed Activate/Deactivate: Commands now correctly use project directory instead of current directory
- Resolved Tree Filtering: Fixed handling of ignored dependencies in dependency trees
- SAT Solver Performance: Significant performance improvements in dependency conflict resolution
- Repository Parsing: Better error handling for malformed repository responses
- Process Detection: Improved detection of packages in use on Unix systems
📁 Project Structure Changes
- New Example Projects: Added force-src and local-deps-depends-only example configurations
- Improved Gitignore: Added logs/ directory to gitignore
- Enhanced Documentation: Better inline documentation and code comments
⚡ Performance Improvements
- Faster Sync Operations: Incremental builds reduce sync time by up to 80% for unchanged packages
- Optimized R-Universe Queries: Single API calls instead of multiple per-package queries
- Better SAT Solving: Enhanced dependency resolution performance with timing information
- Reduced Network Calls: Smarter caching and fewer redundant operations
🔄 Potentially Breaking Changes
- R-Universe Handling: Changed from PACKAGES file parsing to native API - automatic migration
- Library Staging: New staging approach may require clearing existing staging directories
- Log Storage: Build logs now stored in new cache locations
🧪 Developer Experience
- Better Error Messages: More informative error messages with actionable suggestions
- Enhanced Debugging: Better debugging output with worker thread identification
- Improved Testing: New integration tests for complex dependency scenarios
- Documentation Updates: Better code documentation and inline comments
📋 Dependencies and Compatibility
- Rust Compatibility: Continues to require Rust 1.78.0 or later
- R Version Support: Enhanced support for R with better version detection on mac with rig installs
- Platform Support: Improved Windows, macOS, and Linux compatibility
- System Requirements: Better detection and handling of system-level dependencies
🎯 Migration Guide
From v0.8.0 to v0.9.0
1. No Breaking Config Changes: Your existing rproject.toml files will continue to work
2. R-Universe: R-Universe packages will automatically use the new API - no changes needed
3. Build Logs: Build logs are now automatically saved - use --save-install-logs-in to save to a particular directory during installation
