            Bug ID: 402363
           Summary: File mode always set to 0600 when saving changes
           Product: kompare
           Version: unspecified
          Platform: FreeBSD Ports
                OS: FreeBSD
            Status: REPORTED
          Severity: normal
          Priority: NOR
         Component: general
          Assignee: kompare-devel at kde.org
          Reporter: jhb at FreeBSD.org
  Target Milestone: ---

SUMMARY

When using kompare to apply changes from one file to another, the updated
file's permissions are reset to 0600 (presumably you are creating a new file
with 0600 and renaming it on top of the old file instead of opening and
rewriting the existing file and this is losing the existing permissions as a
result?).  This seems like a regression from kompare in KDE 4.

STEPS TO REPRODUCE
1. echo foo > foo
2. echo bar > bar
3. ls -l foo bar
-rw-r--r--  1 john  john  4 Dec 19 11:58 bar
-rw-r--r--  1 john  john  4 Dec 19 11:58 foo
4. kompare foo bar
<space> to apply delta
Ctrl-Q to quit and save
5. ls -l foo bar
-rw-------  1 john  wheel  4 Dec 19 11:58 bar
-rw-r--r--  1 john  john   4 Dec 19 11:58 foo

OBSERVED RESULT

-rw-------  1 john  wheel  4 Dec 19 11:58 bar

EXPECTED RESULT

-rw-r--r--  1 john  wheel  4 Dec 19 11:58 bar
