>From https://westurner.org/wiki/awesome-python-testing#advanced-debugging :
- https://github.com/lmacken/pyrasite/blob/develop/README.rst mentions
something about codesigned GDB and OSX.
- https://github.com/google/pyringe doesnt mention OSX.
- dtrace probably doesn't help with stack traces or local variables:
Are there error messages?

> Only in rare cases, when debugging the interpreter itself, you use gdb.
> For debugging Python code, use pdb or something better.

> I've tried so far various combinations of pre-compiled GDB from the

> locally compiled GDB from MacPorts, together with a pre-compiled Python
> 2.7, homebrew-compiled 2.7, and custom compiled Python 2.7 from the
> official source tarball.
> My results so far were not successful. The legacy GDB commands to show a
> python stack trace or the local variables - do not work. And the new GDB
> commands (referenced on the Fedora project page) are not present at all in
> any of the GDB versions.
> I've checked the python CI build bot tests, and it seems the new GDB
> commands are only successfully tested on Linux machines, and are skipped on
> FreeBSD, OS X, and Solaris machines.
> Are the new python <-> GDB commands specific to Linux?
> Are there any considerations to take in regards to debug symbols for
> Python / GDB on OSX?
> Has anyone attempted what I'm trying to do?
> I would be grateful for any advice.
