Rather than using
rminside asubprocessshell command, this PR switches to usingsubprocesswithout shell to open the image and thenos.remove. This should resolve any path problems.But there is a twist on macOS - Pillow sleeps before removing the image, and we presumably don't want to make our Python script hang for 20 seconds. Instead, this PR uses
subprocessto start a Python process that sleeps and removes the file afterwards.And since that makes
sleeping before removing the file nicer, this PR addssleepforxdg-open, instead of #5950, to help #5945 and #5968
