My system is archlinux 64 bit, and this issue is new for my system. The strange fact is that it did not use to happen since the first day i used kde 4.3.1 and i noticed that few days ago. I cannot remember what might have changed in order to cause that problem 830469 1 mechmg93 2009-09-14 19:03:10 +0000 the problem only seems to be happening with kernel 2.6.31. i downgraded to kernel 2.6.30.6 and the issue disappeared. how is it possible that the newer kernel causes this problem? ps. apart from the kernel package downgrade i also downgraded the nvidia driver package, but it is just the same nvidia version built for another kernel. 830489 2 mechmg93 2009-09-14 19:37:05 +0000 reading the changelog of 2.6.31 from http://kernelnewbies.org/LinuxChanges#head-0c30611399be8bbb1b2c618211b8bf2d342527fb i read about a reimplementation of inotify and dnotify on top of a new filesystem notification infrastructure, so it seems that this is the reason for the problem. 831343 3 mechmg93 2009-09-16 12:06:03 +0000 i did some extra tests in order to see if it's nvidia fault. 1. i installed nvidia-beta driver 190.32 driver 2. i tested nv driver from xorg 3. i disabled composite and i deleted my xorg.conf file in all the above i kept having the same problem using kernel 2.6.31. 831918 4 andresbajotierra 2009-09-17 01:45:57 +0000 If it is a kernel thing it should be affecting all the applications using KDirWatch. Can you test if this also happens on Dolphin ? (example, open a folder in Dolphin, from the outside of the application (a shell, ex. Konsole) try to remove or add a file and see if the Dolphin file list is updated too. If it is not, then we should move this to kdelibs. Thanks 836119 5 koso.spam 2009-09-26 21:59:06 +0000 I can confirm, that Dophin is also affected. For a few weeks using Kubuntu Karmic 9.10 (kernel 2.6.31), I must manualy refresh directory views. 836120 6 andresbajotierra 2009-09-26 22:01:09 +0000 Thanks 840895 7 mechmg93 2009-10-06 10:04:51 +0000 i just tested kernel 2.6.31.2 and the problem remains. 841960 8 mechmg93 2009-10-08 15:15:42 +0000 i tested kernel 2.6.31.2 with new kde 4.3.2 and the copy problem is gone. the only remaining issue is when i cut and then paste a file. The desktop remains unrefreshed. 842959 9 andresbajotierra 2009-10-10 17:22:34 +0000 Mh, if it only happens with the Desktop (desktop:/ kioslave may be) it could be a different issue. Can you confirm you are talking about "desktop:/" instead of "~/Desktop" (or does it fails on both?) Thanks 847204 10 hugo_alobo 2009-10-19 16:16:45 +0000 I can confirm this issue on my computer with the same kernel. It happens not only to ~/Desktop or any other folder (inside Dolphin, Krusader, etc..) but on desktop:/ kioslave too. Procedure: 1- Open desktop:/ on Dolphin 2- Open konsole, "cd" to ~/Desktop and create a file or directory from there. 3- It won't appear on both "Desktop Folder View" and "desktop:/" 848308 11 jay 2009-10-21 17:21:44 +0000 Same problem here in Arch Linux (64-bit) as well with all updates as of today. This is VERY annoying. There is a few weeks left until 4.3.3, so is there any work around I might try to rectify it now?

Both distros using the same version of kde - 4.3.2. Summing up, we must try to find some patches from kubuntu guys. 853119 15 kneczaj 2009-10-30 22:10:24 +0000 I must add that for me downgrading to 2.6.30 and changing driver from nvidia to nv on my arch linux doesn't solve the problem. One more thing: The easiest way to reproduce is opening dolphin and then downloading some file with firefox to the folder opened in dolphin. After that the file should immediatly appear in dolphin but it doesn't. 853567 16 andresbajotierra 2009-10-31 19:23:30 +0000 If this is also happening with Kernel < 2.6.31 (comment 15), then the cause is at another place.. I wonder if you have FAM or other related daemon running. 853629 17 kneczaj 2009-10-31 21:52:54 +0000 I've tried fam and gamin with kernel 2.6.31 without any effect. I don't remember whether I've tested 2.6.30 with or without fam/gamin. I had downgraded only kernel, udev, hal etc. stayed at same version. 856221 18 asraniel 2009-11-05 13:00:33 +0000 *** Bug 210952 has been marked as a duplicate of this bug. *** 856225 19 asraniel 2009-11-05 13:02:56 +0000 *** Bug 212838 has been marked as a duplicate of this bug. *** 861421 20 mboquien 2009-11-14 03:48:37 +0000 *** Bug 214073 has been marked as a duplicate of this bug. *** 861470 21 jithin1987 2009-11-14 07:30:51 +0000 *** This bug has been confirmed by popular vote. *** 863542 22 dav.garcia 2009-11-17 12:59:42 +0000 Hi, This bug has been linked in Launchpad: https://bugs.launchpad.net/ubuntu/+bug/479527 Please have a look there for more details. As far as I know, it doesn't seem to be kernel related (happens in kernel 2.6.28 and 2.6.31), it's only triggered when you follow a symlink with Dolphin and has been there at least since KDE 4.2.4. 863628 23 jay 2009-11-17 14:48:27 +0000 I posted this comment in Launchpad and I will post here too to make sure the proper people see it. ----- I am using Kubuntu 9.10 on my laptop, and Arch on my desktop. Both 64-bit. I am not following any symlinks when this happens, so I am not convinced that it's related to symlinks. I have the problem with both Kubuntu and Arch. In Kubuntu 9.10, it starts off working fine but for some reason, something gets out of sync and the problem starts. With Arch, the problem is always there. For me, here are a few examples of my reproducing this problem in both Arch and Kubuntu: Example 1: 1.) Either set the desktop to a Folder View or include a Folder View on the desktop 2.) Open Firefox 3.) Download a file to the desktop 4.) The download completes 5.) The file is not on the desktop 6.) Right click the desktop and click "refresh" 7.) The file you downloaded now appears Example 2: 1.) Either set the desktop to a Folder View or include a Folder View on the desktop 2.) Find a random file on your desktop 3.) Open Dolphin 4.) Right-click the file chosen on the desktop in step 2, and click "cut" 5.) Go into the Dolphin window and click "Paste" 6.) The file is now moved to the folder you opened in Dolphin 7.) The file is still showing on the desktop 8.) Click on the file on the desktop 9.) It will say the file is not there 10.) Right-click the desktop and click "refresh" 11.) The file disappears Example 3: 1.) Open KTorrent 2.) Open Firefox 3.) Find a torrent to download in Firefox 4.) Send the Firefox open dialogue for the torrent to KTorrent 5.) Choose the desktop as the place KTorrent will save the downloaded torrent to 6.) KTorrent starts downloading the torrent 7.) No files have appeared on the desktop 8.) Right-click the desktop and click "refresh" 9.) The files that KTorrent is downloading now appears on the desktop I deal with this problem in both Kubuntu 9.10 AND Arch with KDE 4.3.3, even after reinstalling my OS completely and/or deleting my .kde and .kde4 folders. This is extremely annoying. I have to babysit my desktop and constantly refresh it manually to see any changes. If I never refresh it, I will never see any changes. 863671 24 sebastien.rohaut 2009-11-17 15:30:01 +0000 My two cents. The problem doesn't occurs only in desktop but everywhere. I found it using ksnapshot / KDE file chooser. As it occurs with 2.6.31 and its new fsnotify/inotify implementation, the problem should come from the kernel or from an old and/orr incorrect use of notify system calls in kdelibs. Three bugs reports are in Novell Bugzilla for openSUSE 11.2 : Two for KDE file refresh https://bugzilla.novell.com/show_bug.cgi?id=547903 https://bugzilla.novell.com/show_bug.cgi?id=544153 One for a true problem with 2.6.31 fsnotify : https://bugzilla.novell.com/show_bug.cgi?id=546491 I don't think it's a coincidence. kdelibs4 has been updated sunday in openSUSE KDE 4.3.x repositories : * dim. nov. 15 2009 dmueller@suse.de - refresn patches It's seems it works now. I don't know what are these patches. From Novell bugzilla #546491, Andreas Gruenbacher: I have pushed two fixes into the 11.2 git tree; they should show up in the KOTD in a while. Could you please see if they make a change? Changelog entry: - patches.fixes/dnotify-ignore-FS_EVENT_ON_CHILD.diff: dnotify: ignore FS_EVENT_ON_CHILD. - patches.fixes/inotify-fix-coalesce-duplicate-events-into-a-single.diff: inotify: fix coalesce duplicate events into a single event in special case. So there was a problem. I didn't test the kernel fix. i will do tomorrow. But I can confirm current 2.6.31 has a problem with inotify, because my own code doesn't work. 863903 25 faure 2009-11-17 21:35:49 +0000 (In reply to comment #22) > As far as I know, it doesn't seem to be kernel related (happens in kernel > 2.6.28 and 2.6.31), it's only triggered when you follow a symlink with Dolphin > and has been there at least since KDE 4.2.4. You're confusing bugs. You're talking about bug 213799, which I fixed for 4.4.0. However there -is- a kernel-related bug, I'm sure of that, since kdelibs/kio/tests/kdirlistertest worked fine before I upgraded from 2.6.28 to 2.6.31 (kubuntu karmic). Comment #24 has more details, I see - very cool. 864145 26 dav.garcia 2009-11-18 08:36:22 +0000 Agreed. Thanks for fixing that bug. Just one question: do you know whether the fix for bug 213799 is being backported to a 4.3.X release?

Makes KDE pretty much worthless for file management. 866546 29 jay 2009-11-22 18:17:56 +0000 I agree. Waiting to fix this would be silly because KDE is essentially broken right now. This worked fine in the initial release of KDE 4.3.0 so it should work fine now. This bug has basically ruined my KDE 4.3.x experience. This is not just a small flaw, this is HUGE. 866867 30 mr 2009-11-23 09:55:11 +0000 Hey, please backport the fix. Now it's total pain to use KDE. 869674 31 andresbajotierra 2009-11-27 22:21:44 +0000 The fix which is not going to be backported is the one for bug 213799 (only related to *symlinks*....). The inotify issue was not even fixed on KDE SC 4.4 yet... If you want that issue(symlinks) to be backported then your comments should be in *that bug report* and not into this... otherwise this was a misunderstood...
