Bug ID: 388071
Summary: KMountPoint doesn't handle bind mounts correctly,
breaks Trash
Product: frameworks-kio
Version: unspecified
Platform: Other
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: general
Assignee: fa...@kde.org
Reporter: bugreporte...@protonmail.com
CC: kdelibs-b...@kde.org
Target Milestone: ---
KMountPoint doesn't determine the correct mount point, if there are bind
mounts. This breaks the Trash handling, files from other devices are moved to
the home directory trash folder instead of the trash folder on the other
device.
dd if=/dev/zero of=/tmp/test-disk1 bs=1024 count=10000
dd if=/dev/zero of=/tmp/test-disk2 bs=1024 count=10000
mkfs.ext4 /tmp/test-disk1
mkfs.ext4 /tmp/test-disk2
mkdir /mnt/test-disk1
mkdir /mnt/test-disk2
mount -o loop /tmp/test-disk1 /mnt/test-disk1
mount -o loop /tmp/test-disk2 /mnt/test-disk2
mkdir -p /mnt/test-disk1/aaa
mkdir -p /mnt/test-disk2/aaa/bbb
touch /mnt/test-disk2/aaa/bbb/file
mount --bind /mnt/test-disk2/aaa/bbb /mnt/test-disk1/aaa
Stat:
# stat /mnt/test-disk1
File: /mnt/test-disk1
Size: 1024 Blocks: 2 IO Block: 1024 directory
Device: 701h/1793d Inode: 2 Links: 4
# stat /mnt/test-disk2
File: /mnt/test-disk2
Size: 1024 Blocks: 2 IO Block: 1024 directory
Device: 702h/1794d Inode: 2 Links: 4
# stat /mnt/test-disk1/aaa/file
File: /mnt/test-disk1/aaa/file
Size: 0 Blocks: 0 IO Block: 1024 regular empty file
Device: 702h/1794d Inode: 13 Links: 1
------------------------------------------------------
KMountPoint::currentMountPoints():
#include <QDebug>
#include <KMountPoint>
int main() {
const QString origPath = "/mnt/test-disk1/aaa/file";
KMountPoint::Ptr mp =
KMountPoint::currentMountPoints().findByPath(origPath);
qDebug() << mp->mountPoint();
}
-------------------------------------------------------
Which returns: "/mnt/test-disk1/aaa", while the file resides on test-disk2.
