Not working on Fedora 35

Hi,

I'm getting the following error while trying to use any of the tools:

Looks like it's due to clashing module names. I guess you have the python proc package installed and pSnapper imports that instead of its own proc package. I guess I'll change the package name in the future to prevent such clashes, but for now you could either uninstall the python proc package if you don't use it or set up the pythonpath environment variable as a workaround for pSnapper.

# sudo psn -p "mysqld|kwork" -G syscall,wchan

  File "/usr/bin/psn", line 113, in <module>

I tried changing the PYTHONPATH, but hit some other errors, a temporary workaround (if you can't remove the clashing proc package) is to rename pSnapper's proc.py to psnproc.py and change imports in 2 files.

1. mv /usr/lib/0xtools/proc.py mv /usr/lib/0xtools/psnproc.py
2. change import proc to import psnproc as proc in /usr/lib/0xtools/psnreport.py
3. change import proc, psnreport to import psnproc as proc, psnreport in /usr/bin/psn

Or just remove the separate clashingproc package with pip uninstall proc as described above.

I'll fix this naming clash in the next release.

Hi @tanelpoder

Tried your solution, it worked perfectly fine.
I had python proc module installed using pip.

This tool is simply amazing, I think we need to produce an RPM/DEB packages for such great tool !!!

[tanelpoder]

Thanks :-)

There's actually a PR already for RPM generation (#18). But I was the bottleneck last year getting this completed. But I plan to be more active this year (and any help is appreciated).

[bu3ny]

I'll try to open a RFE to include it in upcoming RHEL release.

[tanelpoder]

That would be great! I'd be happy to make any changes to file & directory locations etc and anything that's needed for proper standardized deployment to Fedora/CentOS appstream/RHEL environment.

Fixed in v1.2.3
