#37381 [Com]: auto_globals_jit fails to correctly intialize variables
ID: 37381 Comment by: php at modem-help dot com Reported By: gcp at sjeng dot org Status: No Feedback Bug Type: Variables related Operating System: FreeBSD 6.0 PHP Version: 5.1.4 New Comment: PHP 5.1.6 (RedHat FC6; std PHP, Apache; fully updated) `auto_globals_jit = On' works fine with 'normal' PHP scripts. However, when included via `auto_prepend_file' $_SERVER is completely absent (together with other Globals). Test case: file script: httpd.conf: AddType application/x-httpd-php .html php_value auto_prepend_file "/path/to/test/file" php.ini: variables_order = "EGPCS" register_globals = Off register_long_arrays = Off register_argc_argv = On auto_globals_jit = On The above produces nothing ($_SERVER is absent). Change `auto_globals_jit' to `Off' (plus `apachectl graceful') and it works.

I've encountered the same problem, with a normal rpm installation of
php-5.1.4-1 which ships with FC5.
A simple reproducable script would be
which returns NULL if auto_globals_jit is set to on (default in this
rpm package). This is the same deal with $_REQUEST, which is also
NULL.
Now, even if auto_globals_jit is set to false, $_GLOBALS is still not
available.

Thank you for this bug report. To properly diagnose the problem, we
need a short but complete example script to be able to reproduce
this bug ourselves.
A proper reproducing script starts with ,
is max. 10-20 lines long and does not require any external
resources such as databases, etc.
If possible, make the script source available online and provide

Description:
In some circumstances, global variables will fail to be initialized
when auto_globals_jit is enabled (the default). This is a regression,
the problem did not exist in 5.1.2.
php.ini is default recommended one. Server is lighttpd 1.4.11 using PHP
in FastCGI mode.
Reproduce code:
---
Using for example, phpMyAdmin 2.8.0.3, and looking in the
libaries/Config.class.php code:
function checkPmaAbsoluteUri()
{
// Setup a default value to let the people and lazy syadmins
work anyway,
// they'll get an error if the autodetect code doesn't work
$pma_absolute_uri = $this->get('PmaAbsoluteUri');
if ( strlen($pma_absolute_uri) < 1 ) {
$url = array();
// At first we try to parse REQUEST_URI, it might contain
full URI
if ( ! empty($_SERVER['REQUEST_URI'] ) ) {
$url = parse_url($_SERVER['REQUEST_URI']);
}
// If we don't have scheme, we didn't have full URL so we
need to
// dig deeper
if ( empty( $url['scheme'] ) ) {
// Scheme
if ( ! empty( $_SERVER['HTTP_SCHEME'] ) ) {
$url['scheme'] = $_SERVER['HTTP_SCHEME'];
} else {
$url['scheme'] =
!empty($_SERVER['HTTPS']) &&
strtolower($_SERVER['HTTPS']) != 'off'
? 'https'
: 'http';
}
etc...
It's possible to enter this function with $_SERVER missing essential
things such as HTTP_HOST:
array(4) {
["PHP_SELF"]=>
string(21) "/mysqladmin/index.php"
["PHP_AUTH_USER"]=> (censored)
["PHP_AUTH_PW"]=> (censored)
["REQUEST_TIME"]=>
int(1147178223)
}
If auto_global_jit is disabled, this does not not happen, and HTTP_HOST
etc are set correctly.
