Version: (using Devel)
Installed from: Compiled sources

Having mounted a remote samba share via cifs (or smbfs) i noticed
dolphin crashes / freezes when trying to change the sort mode or view
mode on a directory that my user has no write-permissions on the server.
(yet the share is being mounted as rw). Changing the mount options to ro
(read-only) fixes the issue, yet I think dolphin shouldn't crash /
freeze in such a situation, but handle the error gracefully. It appears
it tries to write a lock-file in this directory - which it obviously
fails to do.

I experience the same kind of freeze of dolphin on my NAS (mounted "rw")

I have write permissions on the directory.
BTW: Thanks a lot for dolphin - it is a great application!

I have the problem, too, with trunk (kdebase rev. 816127). If I remove
the .directory.lock file by hand (which I can do as the same user as
dolphin runs on cifs), dolphin unfreezes and changes the settings. I
guess it should a) not freeze on any view mode changes and at least
timeout and b) should work in default here. But this is only my 2 pence.
I hope you fix it somehow.

I can confirm Dolphin hangs on change of view mode while navigating cifs mount. When run from command line, it complains of "problem deleting stale lockfile". Deleting .directory.lock manually does unfreeze but only until the next view change. Since I mount most of my home directory over cifs, this is a bit of showstopper.

@David: I cannot reproduce this issue - although I've write access to my
samba-share, Dolphin (correctly) stores the .directory files mirrored
inside ~/.kde4/share/apps/dolphin -> no locking.
I had a look at the code and from my point of view Dolphin should never
try to write on non-local directory. Inside ViewProperties.cpp there is
the following check (simplified here - 'url' is the input, m_filePath
the path where the .directory file will be written):
KUrl cleanUrl(url);
cleanUrl.cleanPath();
m_filepath = cleanUrl.path();
...
if (cleanUrl.isLocalFile()) {
const QFileInfo info(m_filepath);
if (!info.isWritable()) {
m_filepath = destinationDir("local") + m_filepath;
}
} else {
m_filepath = destinationDir("remote") + m_filepath;
}
Where destinationDir() is implemented like this:
QString ViewProperties::destinationDir(const QString& subDir) const
{
QString basePath = KGlobal::mainComponent().componentName();
basePath.append("/view_properties/").append(subDir);
return KStandardDirs::locateLocal("data", basePath);
}
I'm confused now as cleanUrl.isLocalFile() should return false in the
case of cifs/smbfs and hence never may touch the .directory file. And
even if true would be returned, then isWritable() may not return true if
it is not writable.
>From a quick look at this code: Do you see a general flaw here? Thanks!

yes, it looks like dolphin checks the timestamp on the .directory file
like: "m_node->timestamp() < settings->viewPropsTimestamp()". I'm pretty
sure this is error prone for mounted devices, as it will probablt get
the server timestamp. So if the date/time on the server does not match
exactly the one on the client, this could cause trouble in theory. I
just can't see how it could make dolphin hang though. Maybe this helps.

Additional behaviour I've observed: Dolphin will crash if you try to
switch view or sort mode on ANY directory, whilst you have a SMBFS/CIFS
directory open. So, if you have an SMBFS/CIFS window open, split the
view, use the second pane to navigate through the local filesystem and
then try and change view/sort mode on the local fs, Dolphin will freeze
as there is an SMBFS/CIFS window open, even though this is not the
directory you are trying to sort.
This applies even if the SMBFS/CIFS system is open in a completely
Dolphin window; changing view or sort on the local fs will still cause
Dolphin to freeze.

Doh, I first tested with a NFS mount, but those work fine.
With smbmount I see "couldn't lock local file" indeed, for a readonly mount
(this is because smbmount doesn't adjust permissions like nfsmount does, for a readonly mount, so the permissions seem to indicate that the directory is writable, while it is not). Ah, with a readwrite mount I finally get the bug.

etc. forever. Definitely a KLockFile bug. Investigation showed:
lockFile() always returns LockFail, even though it creates the lock file
fine.
173 if (st_buf != st_buf2 || S_ISLNK(st_buf.st_mode) || S_ISLNK(st_buf2.st_mode))
174 {
175 // SMBFS supports hardlinks by copying the file, as a result the above test will always fail

181 }
182 return KLockFile::LockFail;
The first if() is indeed always false, but the second one too:
st_buf.st_nlink is 2, st_buf2.st_nlink is 2 as well, and the st_ino differ indeed.
So I have a patch which fixes this, but KLockFile is still VERY slow locking that file (i.e. every time I click on the view mode change button!), because of the slow testLinkCountSupport() code that the snipped code in the above if runs... Ouch I wanted to ask the author of the code about all this, but that's Waldo...

bjoern: Thanks for the tip. It solved the problem for me on two out of

Just a warning though: According to the mount.cifs man page you should
NOT use this workaround if your share spans more than one disk partition
on the server, as that would give you duplicate inode numbers on the
client (two files, same mount, same inode number = trouble).

This bug not only freezes dolphin but also all applications which are
trying to access the share (including konsole windows). Worse, many of
these processes (including dolphin) share instances, and *cannot be
terminated even by SysRq commands*. As a result, rebooting is necessary.
This is a severe bug, and needs to be treated as such.
