[Bug-tar] Symlink extraction broken w/recent CVS versions

[MrC]

It appears that symlink extraction is broken in recent CVS versions of tar.

Here's a directory tree, with two symlinks:

# ls -lR /tmp/test
/tmp/test:
total 4
-rw------- 1 root root    0 May 31 13:03 a
-rw------- 1 root root    0 May 31 13:03 b
drwx------ 2 root root 4096 May 31 13:23 somedir/

/tmp/test/somedir:
total 0
lrwxrwxrwx 1 root root 4 May 31 13:23 a -> ../a
lrwxrwxrwx 1 root root 4 May 31 13:23 b -> ../b


Tar archive is create just fine, and is shown to contain:


# ~/build/tar-cvs/src/tar -tvf /tmp/test.tar
drwx------ root/root         0 2007-05-31 13:03 test/
drwx------ root/root         0 2007-05-31 13:23 test/somedir/
lrwxrwxrwx root/root         0 2007-05-31 13:23 test/somedir/a -> ../a
lrwxrwxrwx root/root         0 2007-05-31 13:23 test/somedir/b -> ../b
-rw------- root/root         0 2007-05-31 13:03 test/a
-rw------- root/root         0 2007-05-31 13:03 test/b

However, upon extraction, symlinks a and b are not created correctly, and
become dead links:

# mkdir extract
# cd extract
# ~/build/tar-cvs/src/tar -tvf /tmp/test.tar
# ls -lR 
.:
total 4
drwx------ 3 root root 4096 May 31 13:03 test/

./test:
total 4
-rw------- 1 root root    0 May 31 13:03 a
-rw------- 1 root root    0 May 31 13:03 b
drwx------ 2 root root 4096 May 31 13:23 somedir/

./test/somedir:
total 0
lrwxrwxrwx 1 root root 1 May 31 13:25 a -> a
lrwxrwxrwx 1 root root 1 May 31 13:25 b -> b
