The drgn debugging tool is structured to provide a powerful, interactive interface for low-level system introspection, particularly for the Linux kernel. The architecture centers around a Command-Line Interface (CLI) & Shell that serves as the primary user entry point. This CLI dispatches commands to the Python API & Core Utilities, which acts as a crucial abstraction layer. This Python layer, in turn, invokes low-level operations on the Core Debugging Engine (C/Python Bindings). The Core Debugging Engine is the direct interface to the Target System, handling memory access, symbol resolution, and raw data interaction. Specialized Linux Kernel Helpers are built upon the Python API & Core Utilities to simplify kernel-specific debugging tasks. Finally, Contributed Scripts & Examples leverage both the core Python API and kernel helpers to provide higher-level debugging functionalities. Data flows from the Target System up through the Core Debugging Engine and Python API to be presented to the User via the CLI.
The end-user interacting with the drgn system. This component represents an external actor and does not have internal source code references within the project.
