Changelog

All notable changes to VritraAI will be documented in this file.

0.30.1 - 2025-12-18

Added

  • Shell-semantics-based execution philosophy - Complete redesign of command execution logic based on shell behavior, not command names
  • VritraAI inbuilt command whitelist - Clean whitelist system for internal commands that bypass shell TTY detection
  • has_pipe_or_redirect() function - Smart detection of shell operators (pipes, redirects, background) to determine interactivity
  • drain_input_buffer() function - Aggressive input buffer draining to prevent leftover characters after interactive commands
  • is_vritraai_inbuilt_command() function - Check if command is internal VritraAI command that should bypass shell logic

Fixed

  • Dangerous command false positives - Fixed is_dangerous_command() to use word-boundary matching instead of substring matching (e.g., ddddddd no longer matches dd)
  • Bash command error recovery - Fixed error recovery not triggering for missing bash script files
  • Interactive command input buffering - Fixed issue where Node.js and other stdin-reading commands left characters in buffer after Ctrl+C
  • Python/Node.js script execution - Fixed python file.py and node script.js getting stuck due to incorrect interactivity detection
  • Terminal unresponsiveness after Ctrl+C - Fixed terminal becoming unresponsive after interrupting interactive commands

Changed

  • Command execution logic - Completely redesigned to use shell semantics (pipes/redirects = non-interactive, otherwise = interactive)
  • Removed hardcoded command detection - No longer uses hardcoded lists of interactive commands (python, node, etc.)
  • Interactive command detection - Now behavior-based (checks for shell operators) instead of name-based
  • Input buffer management - Enhanced with aggressive draining (20 flushes + non-blocking reads up to 10,000 bytes)

Improved

  • Command execution reliability - All interactive commands now work correctly without hardcoding
  • Terminal state management - Better terminal state restoration and input buffer clearing
  • Error recovery - Enhanced error recovery for bash commands with missing files
  • Dangerous command detection - More accurate detection using word boundaries and exact matches
  • Input buffer draining - Multi-stage draining process (flush → non-blocking read → final flush)

Technical Details

  • Created VRITRAAI_INBUILT_COMMANDS set with all internal commands
  • Implemented has_pipe_or_redirect() for shell operator detection
  • Enhanced reset_terminal() to use new drain_input_buffer() function
  • Updated signal handler to use aggressive input draining
  • Modified all interactive command paths to use new draining mechanism
  • Deprecated old is_interactive_command() function (kept for backward compatibility)

0.30.0 - 2025-12-18

Added

  • Sudo command support - Full sudo command execution with color preservation
  • Sudo command validation - Checks if commands exist before execution
  • Sudo autocompletion - 30+ common sudo commands available via tab completion
  • Sudo security warnings - Detects and warns about dangerous sudo operations (rm -rf, dd, etc.)
  • Parent directory path support - Added support for .. standalone command and ../folder, ../../folder, etc.
  • Home directory expansion - Added support for ~, ~/Documents, ~/script.py
  • Directory navigation - Automatic directory change when using ./folder or /path/to/folder
  • Error recovery mode - AI-powered error recovery for missing files and paths
  • Similar file suggestions - Fuzzy matching suggestions when files/paths don't exist
  • Visual feedback - Enhanced visual feedback for directory changes and script execution
  • Chain command blocking - Blocks dangerous commands (sudo, bash, path commands) in chain commands
  • Path validation warnings - Detects suspicious path traversal patterns (more than 3 ../)

Fixed

  • Sudo color output - Sudo commands now preserve colors (ls colors, grep colors, etc.)
  • Sudo output capture - Fixed sudo command output capture for explain_last functionality - now properly logs actual command output instead of generic messages
  • Dangerous command detection - Fixed detection for sudo rm -rf * and similar dangerous patterns
  • Path handling - Fixed ~ standalone command (now works without /) and .. standalone command
  • File execution - Fixed interactive script execution for ./test.py and ./test.sh
  • Python error recovery - Fixed error recovery for python xyz.py when file doesn't exist

Changed

  • Default model - Changed default Gemini model from "gemini-2.0-flash" to "gemini-flash-latest" (gf4)
  • Sudo execution - Sudo commands now run in bash shell with environment preservation
  • Command blocking - Enhanced blocking of shell commands and dangerous operations

Improved

  • Sudo handling - Complete rewrite of sudo command handling with security features
  • Error messages - More informative error messages with specific suggestions for different file types
  • Command validation - Better validation before command execution (checks command existence and syntax)
  • Security - Enhanced security checks for dangerous operations
  • File execution - Restricted to only .py and .sh files with strict validation
  • Shell command blocking - Blocked all shell commands except bash (with restrictions)
  • Bash command restrictions - Only allows bash script.sh, blocks bash alone and in chain commands
  • VritraAI command blocking - Prevents launching VritraAI inside VritraAI shell

0.29.5 - 2025-12-01

Added

  • Safe mode command - Introduced safe_mode command for enhanced security and command validation
  • Smart interactive command detection with comprehensive pattern matching
  • Enhanced error recovery system with AI-powered suggestions
  • Traceback sanitization to improve AI error analysis accuracy
  • Support for detecting interactive commands with flags (-i, --interactive, -it, -ti)
  • Improved detection of "command not found" errors (exit code 127)
  • Enhanced history command with timestamps, head/tail piping support, and duplicate prevention
  • Comprehensive path expansion for ~ and environment variables across all file/directory commands
  • Enhanced AI context system - all AI requests now include full system info, directory structure, and project details
  • Improved command validation - detects and rejects invalid flags/arguments before launching interactive shell
  • expand_path() helper function for consistent path expansion across all commands
  • build_comprehensive_context() function for rich AI context with system and directory information

Fixed

  • Interactive commands now work properly - Fixed issue where interactive commands (vim, nano, python, node, docker exec -it, etc.) would get stuck without output
  • Error recovery for system commands - System commands like bash test.sh (when file doesn't exist) now properly show recovery options menu
  • AI error analysis - Traceback sanitization removes vritraai.py references so AI focuses on user's actual errors instead of shell wrapper code
  • Improved terminal handling for interactive subprocess commands
  • Better error message detection from stderr for "not found" type errors
  • History command display - Now correctly counts and shows only commands (not timestamps as separate entries)

  • History duplicate entries - Fixed issue where commands were being saved twice with file locking and duplicate detection
  • Invalid flag/argument handling - Now properly detects and rejects invalid flags and non-flag arguments
  • OS info detection - Robust error handling for Termux/Android environments with fallback methods

Changed

  • Interactive command execution now uses simpler subprocess approach (matching testt.py implementation)
  • Error recovery system now checks actual error messages from stderr, not just exit codes
  • Enhanced interactive command detection to include more patterns (git commands, docker, kubectl, etc.)
  • Error recovery prompts - AI now provides multiple fix command options (3-5 different approaches) instead of single suggestions
  • Traceback display - Removed full traceback display, now shows only error type and message for cleaner output
  • AI response branding - All AI output now shows "VritraAI:" instead of "AI:" for consistent branding

  • Error recovery - AI suggestions now include multiple fix approaches with step-by-step instructions

Technical Details
