Package: tar
Version: 1.23-1
Severity: important
Hello!
I found a problem in this version of tar.
tho...@boole:/tmp/d $ ar x
../tmp.cgJjcD65ng/target/var/cache/apt/archives/bash_4.1-2_hurd-i386.deb
tho...@boole:/tmp/d $ gunzip < data.tar.gz | tar -xkf -
tho...@boole:/tmp/d $ ls -l bin/sh
lrwxrwxrwx 1 thomas thomas 4 8. Apr 00:23 bin/sh -> bash
tho...@boole:/tmp/d $ ar x
../tmp.cgJjcD65ng/target/var/cache/apt/archives/dash_0.5.5.1-3_hurd-i386.deb
tho...@boole:/tmp/d $ gunzip < data.tar.gz | tar -xkf -
At this point no further progress is being made, and strace tells me:
symlink("dash", "./bin/sh") = -1 EEXIST (File exists)
symlink("dash", "./bin/sh") = -1 EEXIST (File exists)
symlink("dash", "./bin/sh") = -1 EEXIST (File exists)
symlink("dash", "./bin/sh") = -1 EEXIST (File exists)
symlink("dash", "./bin/sh") = -1 EEXIST (File exists)
[...]
dash tries to replace the /bin/sh symlink (which tar -k should prevent),
but there's obviously something wrong.
This should not be specific to using hurd-i386 debs, but I didn't check.
(I found this problem while doing an installation of Debian GNU/Hurd
using Debian's crosshurd package.)
After installing tar_1.20-1_amd64.deb (Debian stable):
tho...@boole:/tmp/d $ rm -rf ./*
tho...@boole:/tmp/d $ ar x
../tmp.cgJjcD65ng/target/var/cache/apt/archives/bash_4.1-2_hurd-i386.deb
tho...@boole:/tmp/d $ gunzip < data.tar.gz | tar -xkf -
tho...@boole:/tmp/d $ ar x
../tmp.cgJjcD65ng/target/var/cache/apt/archives/dash_0.5.5.1-3_hurd-i386.deb
tho...@boole:/tmp/d $ gunzip < data.tar.gz | tar -xkf -
tar: ./bin/sh: Cannot create symlink to `dash': File exists
tar: ./usr/share/man/man1/sh.1.gz: Cannot create symlink to `dash.1.gz':
File exists
tar: Error exit delayed from previous errors
tho...@boole:/tmp/d $ echo $?
2
tar doesn't hang. (I'm not sure that this error message is appropriate
with tar -k, but that's a different issue.)
