Can you use gdb with Python?

Can you use gdb with Python?

A set of GDB macros are distributed with Python that aid in debugging the Python process. You can install them by adding the contents of Misc/gdbinit in the Python sources to ~/. gdbinit — or copy it from Subversion. Be sure to use the correct version for your version of Python or some features will not work.

Which Python is gdb using?

23.3 Extending GDB using Python GDB can be built against either Python 2 or Python 3; which one you have depends on this configure-time option.

How do I run a Python script in gdb?

Use the “file” command. Make breakpoint pending on future shared library load? (y or [n]) y Breakpoint 1 (test.py:3) pending. (gdb) run test.py Starting program: /usr/bin/python test.py and while the entire Python script does run within gdb , the breakpoint is simply never reached.

How do I import gdb into Python?

Explanation

1. GDB embeds the Python interpreter so it can use Python as an extension language.
2. You can’t just import gdb from /usr/bin/python like it’s an ordinary Python library because GDB isn’t structured as a library.
3. What you can do is source MY-SCRIPT.py from within gdb (equivalent to running gdb -x MY-SCRIPT.py ).

What is debugging symbols in Python?

To provide a full debugging experience, the mixed-mode Python debugger in Visual Studio needs debug symbols for the Python interpreter being used to parse numerous internal data structures. Each version of the interpreter also supplies symbol files for a variety of modules.

How many types of debugging are there in Python?

The process of tracking this bugs is called as debugging. There are three types of errors that can occur while coding : Syntax Error, Runtime Error and Semantic Error.

How to script GDB ( with Python ) example?

In this case, gdb interprets the script as being a gdb script, i.e. with gdb commands – and that means, that whatever Python code you may want to write in here, must be wrapped in ” python ” as a starting line and ” end ” at end of the Python code. Again, it would be called with any of these equivalent calls:

Where does the type code come from in gdb?

Type alignment comes from the debugging information; if it was not specified, then GDB will use the relevant ABI to try to determine the alignment. In some cases, even this is not possible, and zero will be returned. The type code for this type.

How to return a type object in gdb?

Return a new gdb.Type object which represents a vector of this type. If one argument is given, it is the inclusive upper bound of the vector; in this case the lower bound is zero. If two arguments are given, the first argument is the lower bound of the vector, and the second argument is the upper bound of the vector.

Where does the type alignment come from in gdb?

The alignment of this type, in bytes. Type alignment comes from the debugging information; if it was not specified, then GDB will use the relevant ABI to try to determine the alignment. In some cases, even this is not possible, and zero will be returned.
