Enhancement Request - Set Process Title

[radio...@gmail.com]

Happy New Year!

 

Thanks to everyone who contributes to WeeWx.     

 

In order to effectively find the WeeWx process in a process list,  I’d like tor suggest that weewxd set the process name when it starts.

 

I’ve tested the “setproctitle” library (GitHub - dvarrazzo/py-setproctitle: A Python module to customize the process title) but would not object to some other process.

 

Here’s the diff for version 5.1.0

 

21a22

> import setproctitle

44a46

>     setproctitle("weewx")

Oops!

 

The call should be

setproctitle.setproctitle(“weewx”)

[Tom Keffer]

Unfortunately, setproctitle is not part of the standard Python library, and would have to be installed separately. Adding a dependency for so little value is not worth it. 

If you want to use it, just add it to the file user.extensions.py. That file is loaded before anything else.

This is a function that I use to find weewx in the process list:

    def chkWeewx(self, wxName='weewx'):

        try:

            result = subprocess.run(

                ["ps", "-eo", "user:20,group:20,args"],

                capture_output=True,

                text=True

            )

            if result.returncode == 0:

                processes = result.stdout.splitlines()

                for line in processes:

                    if wxName in line:

                        fields = line.split(None, 2)

                        wxOwner = fields[0]

                        wxGroup = fields[1]

                        return True, wxName, wxOwner, wxGroup

                return False, wxName, None, None

            else:

                return False, wxName, None, None

        except Exception:

            return False, wxName, None, None

and I call it in this manner

weewxRunning, self.wxName, self.wxOwner, self.wxGroup = self.chkWeewx()\

It doesn't need anything extra.
