� PERMANENT THREADING KNOWLEDGE BASE:
✅ CREATED COMPREHENSIVE DOCUMENTATION:
• docs/POWERSHELL-THREADING-RULES.md - Complete threading guide
• Enhanced ThreadSafeProgressCollector with usage examples
• Added to project structure documentation
• Saved to AI memory for future reference
� CRITICAL RULES DOCUMENTED:
• PowerShell cmdlets can ONLY call Write-* methods from main thread
• Background threads must QUEUE updates, never call Write-* directly
• ProcessQueuedUpdates() must ONLY be called from main thread
• Common mistakes and error symptoms clearly identified
� DESIGN PATTERNS PROVIDED:
• Periodic processing pattern (every 1 second)
• Completion-based processing pattern
• Manual processing points pattern
• Correct Task.WaitAll usage with timeouts
� IMPLEMENTATION CHECKLIST:
• Pre-implementation checklist for new cmdlets
• Debugging tips and error identification
• Code examples for correct and incorrect patterns
• Testing guidelines for threading compliance
� PREVENTS FUTURE REGRESSIONS:
• Clear documentation of the 'golden rule'
• Examples of common threading violations
• Patterns for all background operation types
• Reference for all future PowerShell module development
This ensures we never repeat the same threading mistakes!
ThreadSafeProgressCollector utility:
Thread-safe progress data collection from background threads
Concurrent queues for progress updates and verbose messages
Safe PowerShell method calls only from main thread
Automatic completion handling and queue processing
MultiLayerProgressReporter for 3-layer progress:
Layer 1: Collection progress (overall files with ETA)
Layer 2: File progress (current file with size info)
Layer 3: Transfer progress (bytes with speed calculation)
Hierarchical progress reporting with parent-child relationships
Real-time speed and ETA calculations
Enhanced New-MinIOObject cmdlet integration:
UploadSingleFileWithProgress method with progress integration
Multi-file upload with comprehensive progress tracking
Background thread safety for progress callbacks
Verbose message queuing and processing
Graceful error handling with progress completion
Progress tracking features:
Real-time transfer speed calculation
Estimated time remaining (ETA) for collections
Hierarchical progress bars in PowerShell
Thread-safe verbose logging
Automatic progress completion on success/failure
Architecture improvements:
Separation of concerns: progress collection vs reporting
Background thread compatibility
Memory-efficient concurrent collections
Comprehensive error handling and cleanup
This provides enterprise-grade progress tracking for large file operations with
detailed visibility into collection, file, and transfer-level progress.
- Removed MinIO SDK dependency completely
- Built custom HTTP client with AWS S3 signature v4 support
- Created synchronous operations optimized for PowerShell
- Added real progress reporting during transfers
- Implemented performance metrics in result objects
- Fixed null pointer warnings for code quality
- Removed Write-Host usage from test scripts
- Cleaned up unnecessary DLL dependencies
Available cmdlets:
- Connect-MinIO: Enhanced connection with certificate options
- Get-MinIOBucket: List buckets with sorting and filtering
- New-MinIOBucket: Create buckets with region support
- Test-MinIOBucketExists: Check bucket existence
- Get-MinIOObject: List objects with advanced filtering
- New-MinIOObject: Upload files with real progress
- Get-MinIOObjectContent: Download files with progress
This represents a complete architectural overhaul for better PowerShell compatibility and performance.
- Updated README.md with modern feature descriptions and comprehensive overview
- Enhanced docs/USAGE.md with advanced object listing, directory management, and chunked operations
- Created examples/ directory with 6 comprehensive example scripts:
* 01-Basic-Operations.ps1 - Fundamental operations for beginners
* 02-Advanced-Object-Listing.ps1 - Filtering, sorting, and pagination
* 03-Directory-Management.ps1 - Nested directory structures and organization
* 04-Chunked-Operations.ps1 - Large file handling with performance optimization
* 05-Bulk-Operations.ps1 - Batch processing and automation workflows
* 06-Enterprise-Automation.ps1 - Enterprise monitoring, reporting, and compliance
- Added comprehensive examples/README.md with usage patterns and best practices
- Fixed directory creation warnings (now clean verbose logging)
- Implemented missing Get-MinIOObject cmdlet with full filtering/sorting capabilities
- Added timing and performance metrics to all operations
- Enhanced chunked operations with multi-layer progress tracking
- Improved error handling and resource cleanup
- Removed temporary test files and cleaned up repository structure
- All examples use proper PowerShell output (no Write-Host usage)
- Professional logging with timestamps and structured output
