Symlinks are broken when extracting tar archive #19879
Description
Description
I have a TAR archive that contains symlink(s).
mkdir test
cd test
echo "file1" > file1
ln -s file1 file2
mkdir a
cd a
echo "file3" > file3
cd ..
ln -s a b
cd ..
tar -cf test.tar test
Extracting using tar works fine:
rm -r test
tar -xvf test.tar
ls -lah test
total 24K
drwxr-xr-x 3 michal michal 4.0K Sep 19 09:36 .
drwxr-xr-x 104 michal users 12K Sep 19 09:37 ..
drwxr-xr-x 2 michal michal 4.0K Sep 19 09:36 a
lrwxrwxrwx 1 michal michal 1 Sep 19 09:36 b -> a
-rw-r--r-- 1 michal michal 6 Sep 19 09:36 file1
lrwxrwxrwx 1 michal michal 5 Sep 19 09:36 file2 -> file1
The following code extracts the archive using php:
<?php
$tar = '/home/michal/test.tar';
$targetDir = '/tmp/phpissue';
$phar = new \PharData($tar);
$phar->extractTo($targetDir, null, true);Resulted in this:
ls -lah /tmp/phpissue/test/
total 16K
drwxr-xr-x 3 michal michal 4.0K Sep 19 09:42 .
drwxr-xr-x 3 michal michal 4.0K Sep 19 09:42 ..
drwxr-xr-x 2 michal michal 4.0K Sep 19 09:42 a
-rwxrwxrwx 1 michal michal 0 Sep 19 09:42 b
-rw-r--r-- 1 michal michal 6 Sep 19 09:42 file1
-rwxrwxrwx 1 michal michal 0 Sep 19 09:42 file2
The directory "b" is just an empty file, also the file2 is just en empty file. Both were symlinks.
I expect that those symlinks are correctly extracted.
