Fails to start

[DoDoENT]

OS: MacOS 12.6 on Apple Silicon (M1Pro)
Python: 3.10.6 from Homebrew

When starting cruiz, I get the following output:

$ cruiz
Traceback (most recent call last):
  File "/opt/homebrew/lib/python3.10/site-packages/psutil/_psosx.py", line 343, in wrapper
    return fun(self, *args, **kwargs)
  File "/opt/homebrew/lib/python3.10/site-packages/psutil/_psosx.py", line 401, in cmdline
    return cext.proc_cmdline(self.pid)
ProcessLookupError: [Errno 3] assume no such process (originated from sysctl(KERN_PROCARGS2) -> EINVAL)

During handling of the above exception, another exception occurred:

  File "/opt/homebrew/bin/cruiz", line 8, in <module>
    sys.exit(main())
  File "/opt/homebrew/lib/python3.10/site-packages/cruiz/entrypoint.py", line 138, in main

    raise NoSuchProcess(self.pid, self._name)
psutil.NoSuchProcess: process no longer exists (pid=1100)

And then the app just hangs - no GUI is displayed.

Same thing if I try running from clean virtualenv.

Thanks for the report.

This is failing in the code that is asking if an SSH agent is running, in order to populate the main window status bar.

The code loops over all running processes (via psutils) asking to see if ssh-agent is running by name. That's the part that looks like it's failing. It's almost like there are some short-lived processes, that have been closed between finding their pid, and querying about them.

I've not seen this particular failure before, so need to try to reproduce myself. Although I have an idea for a band-aid.

[markfinal]

Not had any luck in reproducing, so used some advice from psutils docs to work around.

Would you mind trying a development build to see if it helps?

• Git clone this repo
• Checkout the branch mf/issue8_ignore_no_such_process_psutils_for_sshagent
• pip install -e .
• cruiz

Thanks

It works from your branch.

But it doesn't play very nice with Apple's dark theme

Thank you for the quick fix!

[markfinal]

Themes are definitely something on the TODO list to make it a nicer experience.

There's a dark theme (from another pip package) that is semi-good but application specific in the preferences dialog.

I need some more knowledge on how to make Qt play nice with the OS choice.

I'll roll this fix into a patch release now. Thanks for testing.

Fix discussed here is now available on PyPi
