            Bug ID: 424555
           Summary: dolphin doesn't refresh contents of mounted samba
                    shares when they are changed remotely
           Product: dolphin
           Version: 19.12.3
          Platform: Kubuntu Packages
                OS: Linux
            Status: REPORTED
          Severity: minor
          Priority: NOR
         Component: view-engine: general
          Assignee: dolphin-bugs-null at kde.org

  Target Milestone: ---

SUMMARY
When the contents of a mounted samba share are modified remotely, dolphin does
not refresh the view. Even navigating to a different folder and then back or
closing and reopening does not trigger a refresh. Only manual refresh with F5
updates the view.

I can go as far as closing dolphin, reopen it a few seconds later and files
that had been deleted are still there. When I try to access them I get an error
that they don't exist obviously and finally the view is updated.

Furthermore, when having multiple dolphin windows open, manually refreshing the
view in one window does not trigger a refresh in the other windows.


STEPS TO REPRODUCE
1. Mount a samba shared folder
2. View the contents of this folder in dolphin
3. Add/delete/modify files in this folder from another computer

OBSERVED RESULT
The contents of the folder remain unchanged until a manual refresh command is
issued or an error is encountered trying to access the files.

EXPECTED RESULT
The contents of the folder should be updated almost instantly.

SOFTWARE/OS VERSIONS
Windows: 
macOS: 
Linux/KDE Plasma: Kubuntu 20.04
(available in About System)
KDE Plasma Version: 5.18.5
KDE Frameworks Version: 5.68.0
Qt Version: 5.12.8

ADDITIONAL INFORMATION

Modifying the contents of the folder locally through a terminal window does
trigger a refresh. It's only when the changes happen remotely that a refresh
isn't triggered. 

Finally, doing the opposite (modifying the contents of the folder in dolphin
while watching it on a win10 file explorer window) triggers an instant refresh
in file explorer.
