Bug in GNOME extension causes `pamac-checkupdates` to spawn and show notifications every 10 seconds

[doraeric]

Component: GNOME Shell Extension (pamac-updates@manjaro.org)

Overview:

I am reporting a bug involving the pamac-updates@manjaro.org GNOME Shell extension. A fault occurred where the extension began spawning the pamac-checkupdates process continuously, causing a new update notification to appear approximately every 10 seconds.

This was an occasional incident and has not been reproduced since. It is noteworthy that while the bug was active and notifications were appearing, the extension's icon remained visible in the system tray.

System Information:

• Operating System: Manjaro Linux (rolling)
• GNOME Shell Version: 48.4
• Pamac Version: pamac-cli 11.7.3 / libpamac 11.7.3

Evidence from Logs:

System logs captured during the event show the extension encountering errors, which is the likely trigger for the continuous spawning loop. The errors indicate the extension was attempting to access UI elements that had already been destroyed.

When trying to replicate this specific behavior on a clean manjaro gnome stable install I come up with nothing. The journal and looking glass do not generate any errors. I to have seen this behavior once or twice. The behavior might be caused by other extensions?

[kanmeiban]

@HanzelM I have the same issue appear from time to time. Extensions I use:

System:

1. Auto Move Windows
2. Dash to Panel
3. Legacy (GTK3) Theme Scheme Auto Switcher
4. User Themes

User:

1. Bring Out Submenu Of Power Off Button
2. Clipboard History
3. No overview at start-up.

I have the same thing, just enabling "pamac updates indicator" in extensions menu causes the notification to appear every 5-10 seconds, did not even get away after I disabled it nor pkill pamac. Had to uninstall pamac completely, then got stuck with a pamac-manager --updates - command not found spamming at the same rate until a reboot.

[HanzelM]

@kanmeiban @doraeric From your descriptions and extensions I could replicate the specific issue with the specific pamac / libpamac: 11.7.3. After updating to 11.7.4-1 (Current Manjaro stable version) I cannot replicate this anymore by switching the extensions on/of and forcing a downgrade of a package to for the notification to pop.

@dkaszews
Since /usr/bin/pamac-manager is owned by pamac-gtk and removing pamac will also remove the pamac-manager. This behavior seems normal until a reboot or the extension is killed.
