 New Comment:

sorry for some stupid questions of a newbie in this area:

1) how will a normal Linux user get your correction? Will it be included in official packages with
an offical php-release? Or do I have to build the package mod-fpm myself and apply the patch somehow
in the build-process??

2) do you see any relation to the discussion in

https://bbs.archlinux.org/viewtopic.php?id=178551

In this discussion progandy stated that the package mod_proxy_handler currently is a workaround till
a bug in apache (probably 2.4.9) is corrected. He doesn't mention your patch. He obviously
doesn't see this as mod-fpm problem.


All this is very confusing to someone who only wants to use apache as php-enabled webserver.

I added fix_script_name_in_fpm_with_apace_fixed that fixes the previous one (it seems it was an
outdated buggy one, wrong malloc call...). I cannot (or don't know how) remove the old one. In
case someone finds it useful :).

This problem is still unsolved in release 5.5.10.

The archlinux distribution just updated their packages from apache2.2+mod-php to apache2.4 +
php-fpm.

But since php-fpm does not provide a correct content for the array $_SERVER (at least SCRIPT_NAME
seems to be wrong) php-based websites won't run with apache2.4+php-fpm. 

e.g  the software "owncloud" is not able to run on php-fpm.

Is it possible to provide a source correction based on the available patch (if that has been tested)
in one of the next php-releases for standard Linux-distributions?

Description:
------------
When using Apache + PHP_FPM, the SCRIPT_NAME variable is incorrectly set. For 
example, accessing "http://127.0.0.1/sample/test.php/a/b/c",
results in:

ORIG_SCRIPT_NAME: 
SCRIPT_NAME: /sample/test.php/a/b/c
ORIG_SCRIPT_FILENAME: //tmp/sample/test.php/a/b/c
SCRIPT_FILENAME: //tmp/sample/test.php
PATH_INFO: /a/b/c
ORIG_PATH_INFO: 

While when using mod_php, the values are:

SCRIPT_NAME: /sample/test.php
SCRIPT_FILENAME: /tmp/sample/test.php
PATH_INFO: /a/b/c

It is also working fine when using NGINX

Test script:
---------------
A sameple script to reproduce the issue:

<?php
echo("ORIG_SCRIPT_NAME: " . $_SERVER['ORIG_SCRIPT_NAME']);
echo('<br/>');

echo("SCRIPT_NAME: " . $_SERVER['SCRIPT_NAME']);
echo('<br/>');
echo("ORIG_SCRIPT_FILENAME: " . $_SERVER['ORIG_SCRIPT_FILENAME']);
echo('<br/>');

echo("SCRIPT_FILENAME: " . $_SERVER['SCRIPT_FILENAME']);
echo('<br/>');

echo("PATH_INFO: " . $_SERVER['PATH_INFO']);
echo('<br/>');

echo("ORIG_PATH_INFO: " . $_SERVER['ORIG_PATH_INFO']);
echo('<br/>');

?>

And a very simple apache conf:

Alias /sample /tmp/sample
ProxyPassMatch .*/sample/(test.php.*) fcgi://127.0.0.1:9000//tmp/sample/$1
<Directory /tmp/sample/ >
    Require  all granted
</Directory>


Expected result:
----------------
ORIG_SCRIPT_NAME: 
SCRIPT_NAME: /sample/test.php
ORIG_SCRIPT_FILENAME: //tmp/sample/test.php/a/b/c
SCRIPT_FILENAME: //tmp/sample/test.php
PATH_INFO: /a/b/c
ORIG_PATH_INFO:
