23.3.2.1 Basic Python. At startup, GDB overrides Python’s sys.stdout and sys.stderr to print using GDB’s output-paging streams.A Python program which outputs to one of these streams may have its output interrupted by the user (see Screen Size).In this situation, a Python KeyboardInterrupt exception is thrown.. Some care must be taken when writing Python code to run in GDB.Two things worth noting in particular:
Page moved: Information on debugging CPython using GDB is now in the main Python documentation, since it is relevant for C extension modules as well. Please read it first: Debugging C API extension...

23.3.1 Python Commands. GDB provides two commands for accessing the Python interpreter, and one related setting: . python-interactive [command] pi [command]. Without an argument, the python-interactive command can be used to start an interactive Python prompt. To return to GDB, type the EOF character (e.g., Ctrl-D on an empty prompt).. Alternatively, a single-line Python command can be given as an argument and evaluated.
There are types of bugs that are difficult to debug from within Python: segfaults (not uncaught Python exceptions) hung processes (in cases where you can't get a Python traceback or debug with pdb) . out of control daemon processes
3 days ago · Debugging C API extensions and CPython Internals with GDB¶. This document explains how the Python GDB extension, python-gdb.py, can be used with the GDB debugger to debug CPython extensions and the CPython interpreter itself. When debugging low-level problems such as crashes or deadlocks, a low-level debugger, such as GDB, is useful to diagnose and correct the issue.
23.3.2 Python API. You can get quick online help for GDB’s Python API by issuing the command python help (gdb).. Functions and methods which have two or more optional arguments allow them to be specified using keyword syntax.
Jan 29, 2024 · Automating Python Scripts for gdb: A Deep Dive. In this article, we will explore how to automate Python scripts for the GNU Debugger (gdb) to handle terminal input, file input, and output, with a focus on automated debugging.
I am running a Python GUI application. I want to invoke and control GDB from it, like load an executable file, set breakpoints etc. I see that GDB has a command line interface which can be used by sending strings to the GDB process, but I want to do it the Python way.
