Description:
------------
When including multiple .phar archieves into the code and one of the archieves contains for example an autoloading script to include files, the script breaks when the reference to the phar wrapper is too far back in the include path. It works anytime when using the phar:// wrapper and not when referencing the file via the include path.

That is not helpful, when the provided autoloader of the framework does not care whether the file is within a different .phar. 

The two used .phars used can be downloaded here:
http://dl.dropbox.com/u/3319901/autoload.phar
http://dl.dropbox.com/u/3319901/libA.phar

Just put those into the root directory with the test script code. To build the .phars I used the export functionality of Zend Studio, as well as a Phing target, both yielded the same results.

Test script:
---------------
<?php

$phars = array( 'phar://libA.phar',
				'phar://autoload.phar');

$usedPath = implode(PATH_SEPARATOR, $phars);

//working with this include path length
//set_include_path(str_pad(PATH_SEPARATOR . $usedPath, 218, 'a', STR_PAD_LEFT));

//NOT working with this include path length
set_include_path(str_pad(PATH_SEPARATOR . $usedPath, 219, 'a', STR_PAD_LEFT));

include 'libA.phar';
include 'autoload.phar';

include 'autoload/autoload.php';

//works at any time
autoload('phar://libA.phar/libA/libA.php');

//NOT working when include path is too long
autoload('libA/libA.php');

Expected result:
----------------
included file phar://libA.phar/libA/libA.php
included file phar://libA.phar/libA/libA.php

Actual result:
--------------
included file phar://libA.phar/libA/libA.php
Warning: include() [function.include]: Failed opening 'libA/libA.php' for inclusion (include_path='aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa;phar://libA.phar;phar://autoload.phar') in phar://autoload.phar/autoload/autoload.php on line 5

Same on PHP 5.3.8 on Win 7 64Bit

Works as expected on PHP Version 5.3.8-ZS5.5.0 / Debian 2.6.32-5-amd64

I have the same problem on PHP 5.3.10 / Windows Server 2008 / IIS 7.5.
We have a workaround for now but soon the 218 character limit is going to be an issue for us. Hope you can fix it!

For the record here. This is certainly due to MAXPATHLEN check in the stream 
implementation.

The question now is to verify where it fails, whether in stream core itself or in 
phar. If the sooner, we have some kind of a problem here and could be harder to 
solve.

Temporary work around would be to use aliases.

I can't reproduce this error with 5.3.8-TS or 5.3.14rc2-NTS on Windows 7. I've posted the output of the test script above for 5.3.8-TS.

The test script doesn't pass regardless of turning off the str_pad calls. Could there be something wrong with the 2 phar files themselves?

What INI directives are you using? 

The PHAR section of my INI file is:
[Phar]
;phar.readonly = On
; http://php.net/phar.require-hash
;phar.require_hash = On
;phar.cache_list =

I am using the official 5.3.8 build, which has PHAR builtin.

With both set_include_path() calls commented out (ie it should work):

With the second set_include_path() call uncommented (so it should fail), I get:

With the 2nd set_include_path() commented out and the 1st uncommented (so it should pass), instead I get:

Yes, this is likely MAXPATHLEN related.  Since the phars are no
longer available, I can't easily test, but I assume this issue is
practically resolved as of PHP 7.1.0 which introduces support for
long paths and defines MAXPATHLEN to 2048 on Windows.  Or can
anybody still reproduce this with any of the actively supported
PHP versions[1]?
