Conversation
- Introduced a decorator `register_magic` to facilitate the registration of magic classes. - Implemented a magic class registry to manage registered magic commands. - Enhanced `CodeExecutor` to automatically discover and register magic commands from modules in the `magics` package. - Updated existing magic classes (e.g., DebugMagic, HandleMagic, HelpMagic, etc.) to use the new registration mechanism. - Improved error handling during module import and registration processes. - Added fallback behavior in `DebugConsole` for cases where `CodeExecutor` initialization fails.
- Refactored DebugMagic to consolidate remote debugging and tracing functionalities under a unified command structure. - Introduced subcommands for debugging: `remote`, `status`, and `help`, along with detailed usage instructions. - Added trace commands with subcommands for starting, stopping, and showing currently traced functions. - Implemented argument parsing for commands and improved error handling. - Removed deprecated HandleMagic and TraceMagic modules to streamline the codebase.

This pull request introduces a registry system and auto-discovery for IPython magic commands, refactors the
DebugMagicclass to provide unified and user-friendly magic commands for debugging and function tracing, and improves error handling and robustness in the console and magic command registration. The most significant changes are the introduction of a magic class registry, automatic registration of magic commands, and a major overhaul of theDebugMagiccommand interface.Magic command registry and auto-discovery:
register_magic) and utility functions for registering, listing, and unregistering magics inpython/probing/magics/__init__.py. This allows magic commands to be auto-discovered and registered without manual imports.DebugMagic command refactor and enhancements:
DebugMagicto use unified%debugand%tracecommands with subcommands (e.g.,%debug remote,%trace start), improved help messages, argument parsing, and added a cell magic%%probefor code execution with tracing. This makes the interface more consistent and easier to use.Robustness and error handling improvements:
DebugConsoleclass to allow fallback operation if the code executor fails to initialize, and added fallback execution logic in thepushmethod. [1] [2]Remote debugging utilities:
DebugMagic, including improved status reporting, installation, and activation ofdebugpy, with clearer output and error messages. [1] [2] [3] [4]These changes significantly improve the extensibility, usability, and reliability of the magic command system for probing and debugging in the project.
