Moving files results in destroyed Permissions under Linux.

[revast]

I use ultracopier from commandline:
(1.4.0.5 fresh from master, but this also happen with the 1.2.3.6 version)

ultracopier mv ~/Downloads/luckybackup_0.4.9-1_amd64.deb ~/Videos

what should happen:

file gets moved to ~/Videos

permissions via ls -al:
-rw-rw-r-- 1 hero hero 4.8M Mar 15 11:26 luckybackup_0.4.9-1_amd64.deb

via filebrowser:

what happens:

file gets moved to ~/Videos

permissions via ls -al:

Hi,
Can you test if http://doc.qt.io/qt-5/qfile.html#setPermissions-1 + http://doc.qt.io/qt-5/qfile.html#permissions work on your system? I just call this functions.
Cheers,

[revast]

not really a coder, so would be too much work to find out how. If you can write me a simple test program I can compile and try it. I use ubuntu 16.04, and my qt version is 5.6, 5.6.1+dfsg-3ubuntu1xenialoverlay14+fix1 from kubuntu ppa.

I try to compile it against a newer qt version (qt5.9.4) to see if this happens there, too

[alphaonex86]

Try a newer version of Qt else this will be fixed with the new standard C++17, the support will be done into the next years at compiler part.

[revast]

ok, I have tried with qt 5.9.4, and its the same problem.

I do not think it's the compiler's fault? There must be a way to fix this. Maybe you could hack together a test program to try if it's really qt's fault?

[alphaonex86]

No, I don't think.
Test this code: https://pastebin.com/9Kvk1vmN need have into the current path: the file "source" and the file "destination"
Send me the output console or debug report to see if contains "Unable to get the source file permission" and "Unable to set the destination file permission"
See if it's on all file into all path, or just into specific case.

[revast]

hmm. I tried to compile with:

put file called test.c in build folder
qmake -project
qmake
make

but no luck so far:

do you have a hint? or should I try with qtbuilder?

[alphaonex86]

With qt creator, new project, console application, replace the .c file content by the paste bin, compile, run, look into application output

[revast]

ok I have managed to do so
Just to be shure that its right what I did:
I compiled the program, then I did:
touch source
touch destiniation
./test

, no output with qt 5.9.4 as well as qt 5.6.1

[revast]

I guess that it works like it should then.
Does that now mean the problem is not related to qt itself?

[alphaonex86]

and the destination permission is well set as source permission?

[revast]

yes. I tried different combinations of permissions.. It worked as is should...

[alphaonex86]

ok, then this same file, try with ultracopier in debug mode, send me the debug repport

[revast]

ok, I hope I did it right. https://pastebin.com/bh8udZtm

[alphaonex86]

Yes, you have do right, contact me into few day if I forgot

[alphaonex86]

Hi, can you try the new version into git?

[revast]

Yes! I can confirm that it is fixed now.

[alphaonex86]

Then I will publish the version 1.4.0.6 into this days, thanks for your repport, contact me in private to have a ultimate version key

[alphaonex86]

I have pushed a new version, it work too?

[revast]

yes, can confirm. I just recompiled and it works as it should.

[alphaonex86]

ok, 1.4.0.6 release, include this fix

[revast]

cool! Thanks for your enthusiasm.
