User is always reported as "root"

[pauldoo]

Is there an existing issue for this?

• I searched the existing issues and did not find anything similar.

Current Behavior

All process report to be running under the "root" user, not their actual user.

I am using Resources 1.10.2 from Flathub. All processes including those for my own user account show up as user "root". Both in the process list and in the process details dialog (see screenshot).

❯ ps auxww | grep 140036
paulrich  140036  8.7  0.2 1267964 147384 ?      Sl   09:47   0:09 resources
paulrich  154241  0.0  0.0   9156  2376 pts/3    S+   09:49   0:00 grep --color=auto 140036

Expected Behavior

The correct user should be reported for processes, not always "root".

Steps to Reproduce

Install Resources from Flathub (version 1.10.2), open the process list.

Debug Logs

I've not provided everything here, as the logs are long and I'm not 100% certain there's nothing sensitive there. I can provide further pieces of the log if you can tell me what to look for specifically.

Hi, thanks for the issue.
Resources labels processes owned as root if it can't associate the user id with a name. Could you please run

RUST_LOG=trace ~/.local/share/flatpak/app/net.nokyan.Resources/current/active/files/libexec/resources/resources-processes -o -r > /dev/null 2> /tmp/resources-stderr.txt

or

RUST_LOG=trace /var/lib/flatpak/app/net.nokyan.Resources/current/active/files/libexec/resources/resources-processes -o -r > /dev/null 2> /tmp/resources-stderr.txt

(depending on whether you've installed Resources as a Flatpak user-wide or system-wide respectively) in a terminal and look for the string "User of" in the file /tmp/resources-stderr.txt? This search should return all the instances where Resources tried to figure out the user ID of a process.

I've pulled out one example, for firefox:

❯ ps -fp 69603
UID          PID    PPID  C STIME TTY          TIME CMD
paulrich   69603   10827  7 09:03 ?        00:06:59 /usr/lib/firefox/firefox

In the resources log for that process I see this:
