The problem with the isSlow() is that it needs to work out what drive we're on. To handle symlinks, we need to stat the folder - this means we can freeze in the path to work out whether we do things to avoid freezing. Only helps if we do it in advance. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=379994 --- Comment #13 from David Edmundson --- Git commit 09624c713e63563b740385ade86414b9782263ea by David Edmundson. Committed on 26/08/2017 at 11:08. Pushed by davidedmundson into branch 'master'. Don't special case file URLs when processing .desktop files Summary: At first glance this looks faster, as we skip KIO for a simple stat(), but as the result isn't cached we do file lookups on every single mouse move. This also has the side effect of not blocking Plasma when stat-ing a file on a disconnected remote drive. Test Plan: Created two .desktop files one pointing to a dir, another to a file. One had the arrow to expand the folder, the other did not.

https://bugs.kde.org/show_bug.cgi?id=379994 --- Comment #12 from Dennis Knorr --- Hi again :-) regarding the symlink on the desktop version: I fear your proposed solution via desktop files will not work. The problem is, that a creation of a link via gui methods on the desktop does create a symlink as well and not a desktop file. So users will create symlinks. Even if we tell systemadministrators not to create symlinks via scripts. And users want to put links of deep directories within shares on the desktop for their "current projects". Can this not be fixed? Your approach with the isSlow() method seemed to help at the akademy? Could you attach your isSlow-Method patch at the very least so that we could look into it on our own, too? Perhaps we could figure something out? Regarding the file dialog patch: Could you attach the patch or show a git with a branch we could use for testing? Do you have an realistic/pessimistic time estimation how fast the dialog problem can be fixed upstream? For example that it is in the next lts plasma edition and/or in the next kubuntu lts-release? If that's not reasonable, that's okay, but that would be good to know for us :-) Thanks for your support, the limux guys :) -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=379994 --- Comment #11 from Dennis Knorr --- Hey, working late :) For the file dialog patch: Yeah, giving us the patch would be very nice! At least we can play around with it and see, if there's any cases we can test for. How long would a proper real fix take? Just out of curiosity :-D As for the symlink on the desktop, that might work perhaps, i have to ask my colleagues tomorrow and write at the weekend a response.

https://bugs.kde.org/show_bug.cgi?id=379994 --- Comment #10 from David Edmundson --- As for the file dialog, I can give you a patch right now that will work at the expense of removing the blue progress bars underneath the mount points showing how much disk is used. I can't merge that like that as it's clearly just removing a feature, but for you it might be worth the hit. Fixing that properly I think is doable. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=379994 --- Comment #9 from David Edmundson --- I don't think I can easily fix the case of a symlink on the desktop. *BUT* I can fix something that is identical to the end user. Instead of creating a symlink create a .desktop file with the contents: [Desktop Entry] Type=Link URL[$e]=file:///mnt/server This (currently) does still freezes when disconnected, but that one is nice and fixable. Would that work for you? -- You are receiving this mail because: You are watching all bug changes.

--- Comment #5 from Dennis Knorr ---
For complete documentation i add a few backtraces created at the akademy.
The serversetup was done on debian 9 stretch stable with
> apt install samba samba-client
and configured for homes it is configured like it is described in
https://wiki.debian.org/SambaServerSimple
The client was a KDE Neon Developer Edition. Installation is:
> apt install samba-client cifs-utils
Then beware uids/gids and name and groups should be the same. This is not
ultimate necessary, but you could run into strange issues while running
diagnostics.
Then i mount the share.
> sudo mount -t cifs
> -osoft,username=benutzer01,uid=1000,gid=1000,file_mode=0660,dir_mode=0770,password=Benutzer_01
> //192.168.122.150/benutzer01 /mnt/benutzer01/eins/
umounting can be done via "umount /mnt/benutzer01/eins"
Then there are two options.
1. Create a symlink on Desktop to the mountpoint
2. Create a symlink in ~/shares/folder to the mountpoint
Then i kill smbd and nmbd process on the server with kill -9 with a command
like:
ps aux | egrep -i "smbd|nmbd" | awk '{ print $2 }' | tr '\n' ' ' | xargs -IX
sudo kill -9 X
though this version is not working 100% properly and i hard to copy the pids
and kill again.
restart is done via systemctl restart smbd nmbd
With the first option, the desktop freezes though there are short periodic
updates. You can see that, if you activate the seconds on your desktop clock
With the second option, desktop does not freeze, only if you open a file dialog
in kate for example.
Warning:
1. I did NOT test any more Applications at the moment
2. There's a fairly good chance, that System behaviour changes a little bit if
the network device vanishes instead of killing the server. But this is more
hard to test.
3. Another Test could be that the symlink is not linking to the mountpoint but
to a directory or data WITHIN the mountpoint.

https://bugs.kde.org/show_bug.cgi?id=379994 Dennis Knorr changed: What|Removed |Added CC||dennis.kn...@gmx.net --- Comment #3 from Dennis Knorr --- Hi, The problem is, not only the App freezes, but with a certain user configuration which is perfectly possible (as described by viperomega) the entire Desktop freezes. The funny thing is: when i login via tty into the session, i can work there without any problem. But KDE/Plasma freezes. Soon we will have examples if this happens in other Environments with KDE Applications, too. I work for the city of munich (we are not dead yet :) and we could not deploy an graphical mobile client because of this issue. on the other hand, windows does not have that problem of freezing the desktop. It is not a problem if the app which accesses the folder, freezes. But if there's a symlink to that folder on the desktop or in the app, but no activity is there and then the entire Desktop freezes, this is from a business/enterprise standpoint a nogo. >From my point of view, this is not fixed or resolved and i will try to discuss this in the wider community. -- You are receiving this mail because: You are watching all bug changes.
