Description Rached Ben Mustapha 2001-07-02 15:57:29 UTC
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:0.9.2+) Gecko/20010701

Description of problem:
when i create a tar archive with some files hard-linked between them, some
have the leading '/' in their name, causing the file to be hard-linked with
the wrong inode when un-tarred.


How reproducible:
Always

Steps to Reproduce:
1. cd /tmp; tar cf foo.tar /bin
2. mkdir test; cd test
3. tar xf /tmp/foo.tar
4. ls -li bin/*awk*
5. ls -li /bin/*awk*

- or -

1. tar tvf /tmp/foo.tar




Actual Results:  "tar tvf /tmp/foo.tar" gives
-rwxr-xr-x root/root 157884 2000-08-16 19:26:13 bin/gawk-3.0.6
-rwxr-xr-x root/root 0 2000-08-16 19:26:13 bin/gawk link to /bin/gawk-3.0.6

and

in the un-tarred bin directory, gawk has the i-node number of /bin/gawk-3.0.6



Expected Results:  "tar tvf /tmp/foo.tar" should give "bin/gawk link to
bin/gawk-3.0.6"

and

in the un-tarred bin directory, gawk should have the same i-node number as
gawk-3.0.6 in the same directory



Additional info:

1. tar version is 1.3.19
2. when restoring an archive and modifying a file that was badly linked,
the wrong file is modified, so data loss can occur.

Bero: was there a reason for the pulling back from the 1.13.25 packages? Is this
one that missed the rebuilds in February?

Yes, it was missed in the mass rebuild.
