Package: xdu
Version: 3.0-18+b2
Severity: normal
I found that xdu miscounts the size of root directory.
The problem is reproducible as follows.
I used small chroot environment but this problem can occur without chroot.
# mkdir /tmp/chroot
# cd /tmp/chroot
# mkdir -p lib64 lib/x86_64-linux-gnu
# cp /lib64/ld-linux-x86-64.so.2 lib64/
# cp /lib/x86_64-linux-gnu/libc.so.6 lib/x86_64-linux-gnu/
# cp /usr/bin/du du
# find .
.
./lib64
./lib64/ld-linux-x86-64.so.2
./lib
./lib/x86_64-linux-gnu
./lib/x86_64-linux-gnu/libc.so.6
./du
# chroot . /du / > /tmp/du-abs.txt
# cat /tmp/du-abs.txt
156 /lib64
1656 /lib/x86_64-linux-gnu
1660 /lib
1924 /
# du . > /tmp/du-rel.txt
# cat /tmp/du-rel.txt
156 ./lib64
1656 ./lib/x86_64-linux-gnu
1660 ./lib
1924 .
# xdu < /tmp/du-abs.txt
# xdu < /tmp/du-rel.txt
"xdu < /tmp/du-abs.txt" shows following tree as boxes:
* [root] (3740)
* lib64 (156)
* lib (1660)
* x86_64-linux-gnu (1656)
* (1924)
"xdu < /tmp/du-rel.txt" shows following tree as boxes:
* . (1924)
* lib64 (156)
* lib (1660)
* x86_64-linux-gnu (1656)
"[root] (3740)" in "xdu < /tmp/du-abs.txt" is wrong.
The correct total size is 1924 which is described in du-abs.txt and du-rel.txt.
The size 1924 is shown as a unnamed directory under the root directory.
I think "xdu < /tmp/du-abs.txt" should show same as
"xdu < /tmp/du-rel.txt" except top directory name.
