pystack-debugger
The pystack-debugger is to python as jstack is to java.
It's a debug tool to print python threads or greenlet stacks.
Idea stolen from pyrasite.
Install
$ pip install pystack-debugger
Usage
You may need to run it with sudo
.
$ sudo pystack [--include-greenlet] <pid>
Compatibility
The pystack is compatible with CPython 3.8+ in both client side (the debugger)
and server side (the destination process).
Using PyPy may work in client side (the debugger) but it is untested. Do not
attempt to attach a PyPy process as destination. It may lead to unexpected and
undefined behavior, because the pystack debugger uses gdb/lldb to invoke the
CPython ABI.
Development
Run testing on a container environment:
$ podman machine start
$ ./test.sh
$ ./test.sh coverage html
