Bug ID: 449020
Summary: No way to elevate read permissions when opening a
file, no error, blank document shown
Product: kate
Version: unspecified
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: kwrite
Assignee: kwrite-bugs-n...@kde.org
Reporter: rula...@wp.pl
Target Milestone: ---
SUMMARY
KWrite refuses to run with sudo, and claims in the output that it is "not
necessary", because the user will be prompted for elevated permissions when
they want to save the file. But what if permissions prevent KWrite from opening
the file in the first place? There is no prompt for elevated permissions in
this case, nor is there an error message, and KWrite shows an untruth: a blank
document.
STEPS TO REPRODUCE
1. Try to open a file to which you HAVE the r permission, but DON'T have the x
permission for its containing directory (e.g. another user's .ssh/id_rsa.pub)
OBSERVED RESULT
No prompt for elevated permissions, no error message, blank document. An
attempt to save the document _does_ prompt for privilege elevation, resulting
in a risk of overwriting the file without even having seen its contents first.
EXPECTED RESULT
The mechanism for permission elevation should be implemented for opening files
too.
