Is this repo supported?

[Randomneo]

Currently facing a lot problems with this repo on different python3 versions (3.9, 3.7). Different python versions are installed using virtualenvwrapper (if it could possibly help someone), OS: archlinux Linux randomneo-pc 5.12.2-arch1-1 #1 SMP PREEMPT Fri, 07 May 2021 15:36:06 +0000 x86_64 GNU/Linux.

python3.9

Python 3.9.5 (default, May 9 2021, 14:00:28) 
[GCC 10.2.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import sys, importmagic
>>> index = importmagic.SymbolIndex()
>>> index.build_index(paths=sys.path)
>>> exit()
[1] 23741 segmentation fault (core dumped) python

This behavior brakes python programs that uses threads to do the indexing... For example importmagic extension for emacs.

python3.7

>>> import sys, importmagic
>>> index = importmagic.SymbolIndex()
>>> index.build_index(paths=sys.path)

python 3.7 just dups out interactive shell...

If someone faced the same problem downgrade to python 3.6 for me it worked.

[Randomneo]

During investigation I found out that problem appears because of SymbolIndex._name is set to None. get_or_create_index for some reason sets it to 'default' if None provided. But __init__ function wont.

What is also strange that problem appears only on python3.9 and exact point in code that produces seg fault is here

I don't use Python anymore, but @birkenfeld may. That said, importmagic is pure Python, so if it's segfaulting that is a bug in either a package it's importing or Python itself.

[birkenfeld]

I'm using Python at least, but I'm not able to support importmagic, sorry. But this looks a lot like you have different 3rd-party modules installed for the different Pythons, which cause problems when being imported.
