Summary: PharData::extractTo fails for tarball created by BSD
tar
Status: Assigned
Type: Bug
Package: PHAR related
Operating System: Mac OS 10.7.5
PHP Version: 5.4.12

New Comment:
This is the version of tar that comes with Mac OS 10.7.5:
~ $ /usr/bin/tar --version
bsdtar 2.8.3 - libarchive 2.8.3
Files were created using:
tar -zcvf test-bsd.tar.gz test.txt
I have double checked and it indeed creates the PAX format by default, However
the
man page does not make this clear:
http://www.aelius.com/njh/tmp/tartest/tar.1.html
When forcing to the ustar format:
tar --format ustar -zcvf test-bsd-ustar.tar.gz test.txt
Then PharData::extractTo works correctly.

How did you create these tar files? On mac (10.8.2), I did:
tar cvf my-bsd.tar test.txt
This created a ustar format tar file. Yours seems to be a pax format tar file,
which I can't see how that is the default format on mac?

Description:
------------
The extractTo() method in Phar doesn't seem to work with tar archives generated
using the BSD version of the tar tool, which is the version that comes pre-
installed on Mac OS X.
I have uploaded two sample tar files, which both contain a single test.txt file:
http://www.aelius.com/njh/tmp/tartest/test-bsd.tar.gz
http://www.aelius.com/njh/tmp/tartest/test-gnu.tar.gz
When run the GNU generated tar file works correctly but the BSD generated tar
file fails.
This problem came up with trying to install dependencies using composer, that
had been generated using BSD tar on Mac OS X:
https://github.com/composer/composer/issues/1492
Test script:
---------------
<?php
$phar = new PharData('test-gnu.tar.gz');
$phar->extractTo('extracted-gnu');
$phar = new PharData('test-bsd.tar.gz');
$phar->extractTo('extracted-bsd');
Expected result:
----------------
Both the test-bsd.tar.gz and test-gnu.tar.gz should extract the test.txt file.
Actual result:
--------------
Fatal error: Uncaught exception 'UnexpectedValueException' with message 'phar
error: "/tmp/tartest/test-bsd.tar.gz" is a corrupted tar file (checksum

of file "18 uid=1451698731
