Description George Kiagiadakis 2008-07-31 19:53:33 UTC

Version:           1.1 (using KDE 4.1.0)
Installed from:    Debian testing/unstable Packages
Compiler:          gcc version 4.3.1 (Debian 4.3.1-2)
 
OS:                Linux

Steps to reproduce:
1) $ mknod test p
2) open dolphin in that directory
3) get the mouse over the "test" file.
4) dolphin is now freezed.
5) to make it continue, use "echo garbage > test"

As far as I can tell, it just opens the pipe and tries to read its contents, which is obviously the wrong thing to do, as this operation is blocking. That's why it returns to the event loop only if it reads something from the pipe.

Reassigned this issue to Strigi. @Jos: This seems to be an issue when getting the meta information with KFileMetaInfo. The issue can be reproduced when hovering the file if the Information Panel from Dolphin is enabled.

I have strigi disabled and the bug still exists. I belive this is an issue with file contents preview.

Comment 4 Jos van den Oever 2009-01-03 14:18:12 UTC

SVN commit 904860 by vandenoever:

Check whether a file can be opened by QFile.
If a file is not a file, a directory or a symlink, it is not opened for analysis.
QFile::open(QIODevice::ReadOnly) will hang when trying to open a pipe created with e.g. "mknod test p".
