Version: unspecified (using Devel) OS: Linux Hi, I have a bunch of drives in my pc which totals to 9 partitions. I can access them all (except swap, obviously) just fine in Dolphin, however in other applications (QtCreator in this case) i see the file open dialog appear, freeze for ~40 seconds, then i see everything besides the partitions followed by another freeze of ~40 seconds and after that i (finally) see all the partitions. However then the gui is completely non responsive and only seems to do something once every few seconds. Something is obviously seriously wrong, but it's not taking 100% CPU usage. It's not crashing either, just not responsive. I strangely could only reproduce this behavior in QtCreator's file open dialog. But when that one is open is slows down everything that does a file open dialog and dolphin becomes non responsive till i close the dialog. Reproducible: Always Steps to Reproduce: Have udev + udisks installed and running No HAL running (don't know if that matters) Install QtCreator and open a file open dialog in it And you should have a non responsive qtcreator, dolphin and everything else that has a file open dialog open. Actual Results: Non responsive apps that have a file open dialog open. Expected Results: File open dialog should be very responsive and not slowing anything down.

Please try to reproduce with a recent kdelibs/solid version
how recent ? I can reproduce with r1187456 (so, one week old)
I have the same issue with kdelibs r1190424 and non-KDE apps. On my x86_64 Arch Linux box with Qt 4.7 and dbus 1.4.0, QtCreator always freezes when attempting to open a project. The same thing happens when using VLC (1.1.4.1) and attempting to open a file though opening a directory works just fine! Here is the backtrace I consistently get when I run QtCreator through gdb and press CTRL+C when the freeze occurs: #0 0x00007ffff5dab173 in poll () from /lib/libc.so.6 #1 0x00007fffeca8d170 in ??

SVN commit 1190737 by lukas: rework the device cache to use QMetaObject and QMetaProperty, thus avoiding the freezes with newer dbus versions (which was due to a bug in QtDbus) CCBUG: 253039 M +1 -1 udisks/udisks.h M +8 -18 udisks/udisksdevice.cpp M +1 -2 udisks/udisksdevice.h M +8 -18 upower/upowerdevice.cpp M +1 -2 upower/upowerdevice.h WebSVN link: http://websvn.kde.org/?view=rev&revision=1190737
Could you tell me how i can get partitions to automount using udisks? It used to "work" some time ago without changing anything anywhere, but now (since ~ 1 month) i don't see any partitions anymore. Is there a special way to turn this on?

Actually things are worse now. Before there were only freezes for non-KDE apps such as QtCreator. Now I get the noticable delays in KDE apps as well. So I did some digging into the issue a bit, I found that removing the line that attempts to prefill the cache in UDisksManager's ctor (line #60) fixes the lag/freeze issue completely on my system. No clue why such a slow operation is called from the ctor in the first place, but still I am not entirely sure how doing so would cause the lags or freezes either... Can someone experiencing the same issues please try the attached one liner patch and confirm whether or not it resolves the issue for you ?
Created attachment 53007 [details] proposed patch...
Uhm interesting but the proposed patch touches a different piece of code, unrelated to my patch above. I'll investigate more here
SVN commit 1191945 by lukas: patch proposed by adawit (remove the device cache prefill) CCBUG: 253039 M +0 -2 udisksmanager.cpp WebSVN link: http://websvn.kde.org/?view=rev&revision=1191945
Created attachment 53117 [details] proposed patch updated... Here is a better patch. The new patch does the following: 1.) Remove the call to allDevices() from UDisksManager's ctor. Instead a new private method is added to properly initialize the devices list cache before use. 2.) Removes the aggessive caching logic in UDisksDevice::checkCache. It is deterimental to performance when accessing device properties in short live UDisksDevice objects. 3.) Remove the 'result' variable from UDisksManager::allDevices since it is unnecessary and m_deviceCache can be used directly. 4.) Other minor namespace (foreach -> Q_FOREACH) and macro-performance (moving the call for propertyCount() out of the for loop.
well , i am having a kinda similar problem. right now , every dolphin/konqueror file manager/file open operation freezes for 5 to 10 seconds. while it freezes , it displays in strace an infinity of these messages : recvmsg(13, 0x7fff625d3e50, MSG_CMSG_CLOEXEC) = -1 EAGAIN (Resource temporarily unavailable) sendmsg(13, {msg_name(0)=NULL, msg_iov(2)=[{"l\1\0\1<\0\0\0\337\t\0\0\220\0\0\0\1\1o\0%\0\0\0/org/fre"..., 160}, {"\35\0\0\0org.freedesktop.UDisks.Devic"..., 60}], msg_controllen=0, msg_flags=0}, MSG_NOSIGNAL) = 220 poll([{fd=13, events=POLLIN}], 1, 25000) = 1 ([{fd=13, revents=POLLIN}]) recvmsg(13, {msg_name(0)=NULL, msg_iov(1)=[{"l\2\1\1\10\0\0\0:\230\5\0.\0\0\0\6\1s\0\5\0\0\0:1.96\0\0\0"..., 2048}], msg_controllen=0, msg_flags=MSG_CMSG_CLOEXEC}, MSG_CMSG_CLOEXEC) = 72 recvmsg(13, 0x7fff625d3e50, MSG_CMSG_CLOEXEC) = -1 EAGAIN (Resource temporarily unavailable) sendmsg(13, {msg_name(0)=NULL, msg_iov(2)=[{"l\1\0\1:\0\0\0\340\t\0\0\220\0\0\0\1\1o\0%\0\0\0/org/fre"..., 160}, {"\35\0\0\0org.freedesktop.UDisks.Devic"..., 58}], msg_controllen=0, msg_flags=0}, MSG_NOSIGNAL) = 218 poll([{fd=13, events=POLLIN}], 1, 25000) = 1 ([{fd=13, revents=POLLIN}]) recvmsg(13, {msg_name(0)=NULL, msg_iov(1)=[{"l\2\1\1\10\0\0\0;\230\5\0.\0\0\0\6\1s\0\5\0\0\0:1.96\0\0\0"..., 2048}], msg_controllen=0, msg_flags=MSG_CMSG_CLOEXEC}, MSG_CMSG_CLOEXEC) = 72 recvmsg(13, 0x7fff625d3e50, MSG_CMSG_CLOEXEC) = -1 EAGAIN (Resource temporarily unavailable) sendmsg(13, {msg_name(0)=NULL, msg_iov(2)=[{"l\1\0\1?\0\0\0\341\t\0\0\220\0\0\0\1\1o\0%\0\0\0/org/fre"..., 160}, {"\35\0\0\0org.freedesktop.UDisks.Devic"..., 63}], msg_controllen=0, msg_flags=0}, MSG_NOSIGNAL) = 223 poll([{fd=13, events=POLLIN}], 1, 25000) = 1 ([{fd=13, revents=POLLIN}]) recvmsg(13, {msg_name(0)=NULL, msg_iov(1)=[{"l\2\1\1\10\0\0\0<\230\5\0.\0\0\0\6\1s\0\5\0\0\0:1.96\0\0\0"..., 2048}], msg_controllen=0, msg_flags=MSG_CMSG_CLOEXEC}, MSG_CMSG_CLOEXEC) = 72 recvmsg(13, 0x7fff625d3e50, MSG_CMSG_CLOEXEC) = -1 EAGAIN (Resource temporarily unavailable) sendmsg(13, {msg_name(0)=NULL, msg_iov(2)=[{"l\1\0\0019\0\0\0\342\t\0\0\220\0\0\0\1\1o\0%\0\0\0/org/fre"..., 160}, {"\35\0\0\0org.freedesktop.UDisks.Devic"..., 57}], msg_controllen=0, msg_flags=0}, MSG_NOSIGNAL) = 217 poll([{fd=13, events=POLLIN}], 1, 25000) = 1 ([{fd=13, revents=POLLIN}]) recvmsg(13, {msg_name(0)=NULL, msg_iov(1)=[{"l\2\1\1\10\0\0\0=\230\5\0.\0\0\0\6\1s\0\5\0\0\0:1.96\0\0\0"..., 2048}], msg_controllen=0, msg_flags=MSG_CMSG_CLOEXEC}, MSG_CMSG_CLOEXEC) = 72 i am using kde trunk, compiled on 26-11-2010. thanks
well ... updated to current trunk of today and my bug problem seems to be fixed. thanks :)

Sergio, can you find out which entry in the places list is responsible for the blocking?
This was related to upower demon not running ( due to a polkitd screw up ). It's good now for me.
