This Python C extension provides stack unwinding capabilities using three different methods:

• GNU Backtrace
• libunwind
• libdw (DWARF debug info)

• get_stack_gnu(): Stack unwinding using GNU's backtrace functions
• get_stack_unwind(): Stack unwinding using libunwind
• get_stack_dwarf(): Stack unwinding using libdw

The following libraries are required to build the extension:

• libunwind
• libdw
• libelf
• Python development headers

On Debian/Ubuntu:

sudo apt-get install python3-dev libunwind-dev libdw-dev libelf-dev

On Fedora/RHEL:

sudo dnf install python3-devel libunwind-devel elfutils-devel

On Arch Linux:

sudo pacman -S python libunwind elfutils

1. Clone this repository:

git clone <repository-url>
cd python-stack-unwinder

2. Build the extension:

python setup.py build_ext --inplace

import stackunwind

# Get stack trace using GNU backtrace
stack = stackunwind.get_stack_gnu()
print("GNU Backtrace:")
for frame in stack:
    print(f"  {frame}")

# Get stack trace using libunwind
stack = stackunwind.get_stack_unwind()
print("\nlibunwind:")
for frame in stack:
    print(f"  {frame}")

# Get stack trace using libdw
stack = stackunwind.get_stack_dwarf()
print("\nlibdw:")
for frame in stack:
    print(f"  {frame}")
