Description

Details for the Testing release install (from kinfocenter): KDE Plasma version: 5.8.6 KDE Frameworks version: 5.28.0 QT Version: 5.7.1 Kernel Version: 4.12.0-0.bpo.2-amd64 OS Type: 64 Bit Created attachment 108829 [details]
Sample strace of plasmashell
STrace of SourceGuardian shows no activity (in a wait state), but this is what PlasmaShell is looping on continuously with 100% utilisation (small sample)
Does SourceGuardian have some sort of system tray icon? Or just the icon in the task manager? What sort of time period is the strace log over. If it's 5 minutes, then it's not a huge number of lookups. If it's 2 seconds, then it is. Please reset the status to unconfirmed when replying Hi No icon that I'm aware of (no animated icon in the taskbar, either visible or in the "hidden" area, and no option in SourceGuardian for any such icon or alert). Attaching an strace with -tt, runs from 20:35:34.477 thru 20:35:56.05 - in that time it logged 418598 lines strace -v -tt -o strace-sg-openproject.txt -p 30760 30760 is the PID for plasmashell I've gzipped it due to uncompressed size being so large Created attachment 108833 [details]
Detailed strace with timestamps
More detailed strace of issue occurring
Sorry - there is an icon showing in the taskbar for the App itself (to the left of the app text), but nothing animated or controlled/varied by the application that I can tell. I can see that icon file being referenced (I think) in the calls that are happening. If I open bigger projects in SourceGuardian, it appears I get a longer delay. On my desktop machine (SSD+spinning rust) the delay is only a couple of minutes, but on the laptop (which is SSD only) I can get up to 8 minutes before I can get a response from the taskbar again (based on timing the delay today as a sample, opening a project for the first time after a reboot). Update: Issue remains with current updates on both stable and testing environments. *** Bug 392327 has been marked as a duplicate of this bug. *** Is this still a problem with Plasma 5.27? I see another bug was marked as a duplicate of this, but it seems like there's no clear relation to this bug. I'd like to be able to test this bug with an open source app so I can really see what's going on in the code, but I'm not sure what the root problem is here.

Thank you for helping us make KDE software even better for everyone! Hi - this was a long time ago, and I'd need to retest this with current SourceGuardian builds. I know it takes SG a long time to build the file list when it starts (a feature of them, I think, not plasmashell), and I don't recall in recent times it freezing the rest of the system. SourceGuardian is also not open source. Please let me know if you want me to do updated testing. Dear Bug Submitter, This bug has been in NEEDSINFO status with no change for at least 15 days.
