Public bug reported:
Binary package hint: dpkg
Maybe this is a tar bug. It gives an unsettling error message under
dpkg. One or the other should probably change.
First noticed on 6.10 amd64 however can be reproduced on x86 version
also.
Steps to reproduce:
apt-get source <almost any package>
cd <where you build it>
make -f debian/rules binary
...
dpkg-deb: building package `whatever' in `someplace'.
tar: -: file name read contains nul character
For example:
cd /usr/src
mkdir login
cd login
apt-get build-dep login
apt-get source login
cd shadow-4.0.16
make -f debian/rules binary
...
dh_builddeb -plogin
dpkg-deb: building package `login' in `../login_4.0.16-2ubuntu4_amd64.deb'.
tar: -: file name read contains nul character
>From an 'strace -f' of the above:
execve("/bin/tar", ["tar", "-cf", "-", "-T", "-", "--null", "--no-recursion"],
[/* 20 vars */]) = 0
which from the rest of the strace looks like the tar in question. The "tar"
manpage appears to support this usage. However if I run the following
script:
#!/bin/bash
# Script: breaktar.sh
rm -f t1 t2 t3.tar
cat <<EOF >t1
some stuff
EOF
cat <<EOF >t2
more stuff
EOF
printf "%s\0%s\0" t1 t2 |
/bin/tar -cf - -T - --null --no-recursion >t3.tar
I get:
breaktar.sh
/bin/tar: -: file name read contains nul character
although oddly enough t3.tar has the expected contents. The tar
version on 6.10:
$ tar --version
tar (GNU tar) 1.15.91

An older version of tar does not give this error message:
$ tar --version
tar (GNU tar) 1.15.1
breaktar.sh
(no error message)
