Version 2.8.4

Version 2.8.4 - Dec 26, 2025

Version 2.8.4rc2 has been released as the new version, with no new builds released.

I am uncertain as to why the AsyncStream encounters issues with the aforementioned problem. Nevertheless, I intend to investigate and determine if I can resolve this issue for my own learning and interest. Specifically, I will implement a mechanism to halt the process and drain any remaining data before the termination task is executed.

Major Features & Improvements

• Total Commits (git) Since 2.8.2: 137+
• Development Period: December 12-24, 2025

🔄 RsyncProcessStreaming Migration - Complete

• Unified Process Execution Model: All process execution now uses the RsyncProcessStreaming package for event-driven, streaming process handling
• Simplified Handler Management: Introduced ProcessHandlers factory with built-in cleanup hooks to prevent memory leaks and retain cycles
• Real-time Output Streaming: Process output is now streamed in real-time, enabling immediate UI updates and better user feedback
• Files Updated: Estimate.swift, Execute.swift, RestoreTableView.swift, OneTaskDetailsView.swift, ExecutePushPullView.swift, VerifyTasks.swift

📦 ParseRsyncOutput Swift Package Integration

• Extracted rsync output parsing into a reusable Swift Package for improved code reusability and testability
• Unified parsing logic across all rsync output processing operations
• Package repository: ParseRsyncOutput

✅ Comprehensive Testing Framework

• New RsyncUITests target added with initial test suite
• UI tests for arguments and deeplink URLs
• Output processing tests covering:
  • Tail trimming (20-line limit)
  • Directory line filtering
  • Error detection patterns
  • Malformed/empty output edge cases

Core Changes

Process Execution & Streaming

• Refactored ObservableRestore to use RsyncProcessStreaming
• Refactored task verification to use streaming process handlers
• Added streaming support to QuicktaskView
• Refactored rsync version check to use streaming process
• Remove RsyncProcess dependency - replaced with RsyncProcessStreaming
• Streaming handler cleanup refactoring to prevent retain cycles and memory leaks

UI/UX Enhancements

• Improved UI feedback for task progress and completion
• Enhanced progress view with better styling and layout
• Added configuration table view to ProfileView
• Renamed table column from ‘Time’ to ‘Time last’ across multiple views
• Refactored profile deletion UI in ProfileView
• Improved help text for –delete parameter usage
• Better handling of hiddenID in Estimate and Execute operations
• Removed RsyncRealtimeView and related obsolete UI references

Code Quality & Refactoring

• Refactor optional handling patterns with guard-chain flattening and single binding for counts
• Refactor enum cases to camelCase: RsyncCommand, PushPullCommand, OtherRsyncCommand, PlanSnapshots, DayOfWeek
• Variable naming improvements for consistency and clarity across codebase
• Removed unnecessary whitespace and improved code formatting
• SwiftLint configuration updates and inline rule directives
• Refactored UI views for improved readability (AddTaskView, SidebarMainView, TasksView, QuicktaskView)
• Refactored parameter field handling in configuration models with optional fields

Configuration & Settings

• New argument validation feature: Added toggle for argument validation in execution flow
• Added ‘validate arguments’ setting to user configuration
• Improved argument validation with nil checks and proper error handling
• Add dry-run validation to argument checks
• Configuration model improvements with optional parameter handling

Logging & Debugging

• Refactored and cleaned up logging and test code
• Removed rsync output logfile support from log views
• Gated per-line streaming logs behind DEBUG flag
• Added debug threading check for streaming handlers
• Silenced debug print statements in streaming handlers
• Improved logging to use errorMessageOnly with better formatting

Dependencies & Version Updates

• Updated all Swift package dependencies to main branch

Bug Fixes & Stability

• Fixed guard statement order and typo in snapshot and restore operations
• Safely unwrap streamingHandlers before use
• Remove unnecessary [weak self] in processTermination handlers
• Made parameter4 optional to better handle delete flag
• Fix potential nil issues in argument execution

Architecture Improvements

• Unified streaming architecture with simplified process lifecycle
• Improved memory management through explicit cleanup patterns
• Enhanced testability with extracted ParseRsyncOutput package
• Better separation of concerns through handler factory pattern

Dependencies Updated

• RsyncProcessStreaming (streaming process execution)
• ParseRsyncOutput (output parsing and processing)
• RsyncArguments (rsync command arguments)
• RsyncProcess (legacy - being phased out in favor of streaming)
