Bug 889224 – sys-apps/portage: add a toggle for "load average" output

• Product: Portage Development
• Status: UNCONFIRMED ---

[Description Michael Jones 2022-12-31 21:08:19 UTC]

If --nospinner is not the intended option for turning that output off, can an option to prevent printing "Load avg: 3.00, 4.02, 4.84" be provided?

I want all of the other output that I currently have, i just want to turn off the load average output.

This behavior change would make emerge much easier to use with tools like jenkins that try to display the console output in a webbrowser.

Reproducible: Always

[Comment 1 John Helmert III 2022-12-31 21:11:59 UTC]

       --nospinner
              Disables the spinner for the session.  The spinner is active when the terminal device is determined to be a TTY.  This flag disables it regardless.

Not sure why that would be related to the load average output? See also bug 865841.

[Comment 2 Michael Jones 2022-12-31 22:28:07 UTC]

Because it generates output that looks like:

I'm specifically looking for a way to *only* turn off the load average output. I want everything else.

Hm, digging further it seems like the JobStatusDisplay *does* respect --quiet=y in that it doesn't output load average in that case, but it seems like it doesn't do it effectively in all cases.

Just to be precise, assuming Helmert's conclusion is referring to lines 167-8
