** Description changed: Start software-properties-gtk, switch to additional drivers tab. The program will start consuming 100% CPU for quite some time (many seconds or minutes depending on the machine). There is however no way to cancel the operation other than killing software-properties. Trying to close the window or clicking Close button hangs. Test plans ---------- 1. Start software-properties-gtk 1.1. Go to additional drivers tab. 1.2. Click close at the south-east corner or close the window via your window manager. Expected. Window closes immediately. 4. Start software-properties-gtk 4.1. Go to additional drivers tab and wait. - Expected: The viewport will at the end say that either no drivers are available or show a list of drivers such as in the drivers-list.png attachment. The cancel and retry buttons are gone in the latter case. + Expected: The viewport will at the end say that either no drivers are available or show a list of drivers such as in the drivers-list.png attachment. The cancel/retry buttons are gone in the latter case. 2. Start software-properties-gtk and 'top' in a terminal 2.1. Go to additional drivers tab. Expected: The 'python3' command starts consuming 100% CPU. 2.2. Click cancel. - Expected: The aforementioned process is no longer hogging the CPU, indicating that the driver scan really stopped. The retry button is clickable but cancel is not. + Expected: The aforementioned process is no longer hogging the CPU, indicating that the driver scan really stopped. The button is now retry, clickable. 2.3. Click retry. - Expected: The 'python3' command starts consuming 100% CPU. The retry button is not clickable but cancel ist. + Expected: The 'python3' command starts consuming 100% CPU. The button is now cancel. 3. Start software-properties-gtk and 'top' in a terminal 3.1. Go to additional drivers tab. 3.2. Get the PID of the 'python3' process consuming 100% CPU and kill it with kill -29 PID - Expected: The viewport says "An error blabla. Exit status: -29." Retry is clickable but cancel is not. + Expected: The viewport reports the error. Retry is clickable. 5. Start software-properties-gtk 5.1. Introduce a unconditional exception in /usr/lib/python3/dist-packages/UbuntuDrivers/detect.py:system_device_drivers, e.g.: ---> --- /usr/lib/python3/dist-packages/UbuntuDrivers/detect.py +++ /usr/lib/python3/dist-packages/UbuntuDrivers/detect.py @@ -866,4 +866,5 @@ def system_device_drivers(apt_cache=None, sys_path=None, freeonly=False): +print(fooo) '''Get by-device driver packages that are available for the system. <--- 5.2.
