Bug 462696

SUMMARY

Kompare doesn't request superuser privileges, like Kate does, when the user asks to save/commit diff data to a compared file that's in a root-owned directory. Instead of outright denying the user's request, it should ask for permission to do so instead.


STEPS TO REPRODUCE
1. (On Arch Linux, an example: ) "kompare /etc/mkinicpio.conf.pacnew /etc/mkinitcpio.conf"
(On Arch Linux, updates can save new configuration files as ".pacnew" files so that users can manage their changes to their already existing configurations. As it stands, kompare is hindered in attempts to use it in this manner.)
2. Apply differences to the target file
3. Attempt to save the new changes

OBSERVED RESULT
kompare is completely held back from managing file changes for system configuration files

EXPECTED RESULT
kompare should do what it's meant to and instead ask for permissions to touch files instead of rejecting the user
