Bug
Having namespaced paths with spaces causes the
compare_images.rbscript to hang or fail. This was reported in #527.Example Bad Path in Wraith Config File
This bug is happening because the constructed shell command in
compare_images.rbdoes not escape the supplied pathnames resulting in a faultycompareCLI command.What this PR does
The included changes make the pathname strings escaped for the shell.
This will allow people to use spaces for their named paths and the
compare_images.rbscript can correctly compare the files and generate the diff image.
