Bug ID: 419373
Summary: Synchronizer: Files that are linked lose their dates
Product: krusader
Version: Git
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: synchronize
Assignee: krusader-bugs-n...@kde.org

Target Milestone: ---
SUMMARY
When using Synchronizer, files that are linked lose their dates. At least, if a
symlink is added to a folder and it's synchronized: after the synchronization,
in the destination folder, the corresponding linked file loses its date (and
gets the date of the symlink).
This is a (fortunately) reproducible problem.
STEPS TO REPRODUCE
1) Execution of:
mkdir /tmp/source
touch /tmp/source/1.txt --date "2011-11-11 11:11:11 +0100"
mkdir /tmp/dest
cp -a /tmp/source/1.txt /tmp/dest
cd /tmp/source
ln -s 1.txt 1link.txt
2) Execution of:
ls --full-time /tmp/source
and
ls --full-time /tmp/dest
in order to have written information about some dates, for example:
$ ls --full-time /tmp/source
total 0
lrwxrwxrwx 1 user user 5 2020-01-11 12:28:52.269082028 +0100 1link.txt ->
1.txt
-rw-rw-r-- 1 user user 0 2011-11-11 11:11:11.000000000 +0100 1.txt
$ ls --full-time /tmp/dest
total 0
-rw-rw-r-- 1 user user 0 2011-11-11 11:11:11.000000000 +0100 1.txt
3) Use of Krusader to synchronize /tmp/dest (in the left part) and /tmp/source
(in the right part). Note: The only change that Synchronizer suggested was the
copy of the symlink.
4) After the synchronization, execution of:
ls --full-time /tmp/source
and
ls --full-time /tmp/dest
in order to see what has happened to some dates, for example:
$ ls --full-time /tmp/source
total 0
lrwxrwxrwx 1 user user 5 2020-01-11 12:28:52.269082028 +0100 1link.txt ->
1.txt
-rw-rw-r-- 1 user user 0 2011-11-11 11:11:11.000000000 +0100 1.txt
$ ls --full-time /tmp/dest
total 0
lrwxrwxrwx 1 user user 5 2020-01-11 12:30:57.833085753 +0100 1link.txt ->
1.txt
-rwxrwxrwx 1 user user 0 2020-01-11 12:28:52.000000000 +0100 1.txt
Therefore we can see that an existing file (/tmp/dest/1.txt) in the destination
folder has lost its date.
Note: After the copy, it would also be correct that the date of the copied
symlink was the same as its source.
OBSERVED RESULT
An existing file (/tmp/dest/1.txt) in the destination folder has lost its date.
EXPECTED RESULT
The "/tmp/dest/1.txt already existing file in the destination folder...
shouldn't lose its date.
Additionally, it would be better if the date of the copied symlink was the same
as its source.
SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Kubuntu 19.10 and Kubuntu 18.04 LTS
KDE Plasma Version: 5.16.5 and 5.12.9
KDE Frameworks Version: 5.62.0 and 5.44.0
Qt Version: 5.12.4 and 5.9.5
ADDITIONAL INFORMATION
The problem is possibly related to the `KIO::symlink` lines in
synchronizer.cpp.
