After more investigation with added console.log() I found, that in the file d...@rastersoft.com/app/templatesScriptsManager.js the function _processDirectory() is called 300 times a second.
This function can call itself, so it is an infinite loop taking all of CPU. More details (TSM=TemplatesScriptsManager, DM=DesktopManager): 17:20:01.693: DM constructor called 17:20:01.709: TSM constructor called 17:20:01.711: _processDirectory() 17:20:01.712: TSM constructor finished 17:20:01.745: TSM constructor called 17:20:01.746: _processDirectory() 17:20:01.746: TSM constructor finished 17:20:01.884: DM constructor finished 17:20:01.889: _processDirectory() calls itself 17:20:01.890: _processDirectory() 17:20:01.915: _processDirectory() calls itself 17:20:01.916: _processDirectory() 17:20:01.930: _processDirectory() calls itself 17:20:01.930: _processDirectory() 17:20:01.942: _processDirectory() calls itself 17:20:01.942: _processDirectory() 17:20:01.948: _processDirectory() calls itself 17:20:01.949: _processDirectory() 17:20:01.952: _processDirectory() calls itself ... infinite loop every time the parameter, that is passed, has different object adress file[1]=[object instance wrapper GType:GLocalFile jsobj@0xa8a6cc409e8 native@0x58a041c1c440] if you tell me how to extract file address from the passed js object, I will check it. I checked the files.length inside _processDirectory() function - it usually takes values below 10, but sometimes has up to 100, as the loop continues. If I restart the app, the sequence of the values of files.length repeats. After that I went to my ~/Templates folder and removed what was there, and re-run app. No _processDirectory() loop anymore. So the app scans ~/Templates folder recursively and it takes forever to read 5000 files in 1000 folders under ~/Templates. I also suspect the app hits 1024 open files limit in this log message DING: (gjs:75251): GLib-ERROR **: 14:45:47.778: Creating pipes for GWakeup: Too many open files and restarts again, to scan 5000 files, until restarts again. There should be limit on the number of recursive calls/recursive level of the _processDirectory(), so that it will not take forever. Nobody needs a thousand templates files, but one can easily put there a directory with 1000 files under it's subdirectories, especially as many people don't know what the Templates folder is for. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2081198 Title: ding.js is consuming too much CPU To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell-extension-desktop-icons-ng/+bug/2081198/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
