About the file "obstart.php" nothing special, it's a simple test that determines the nature of the account "Gold, premium or free" to view ads or not.
for the second file, I could not see, because it is owned by root and chmod 600.
a sample from the file "obsatrt.php":

Code: [Select]  

$pro = $rest->pro;
$vip = $rest->vip;
$suspendu = $rest->suspendu;   

// si vip = 1, on affiche pas la pub.
if($vip=='1')
{ $pub='0'; }

// si le compte est en gold, on checke la date
if($pro=='1')
{
// on regarde si la date est ok ou non
$jour = substr($date,0 , 2);
$mois = substr($date,3 , 2);
$annee = substr($date,6 , 4);

$expire = mktime('0','0','0',$mois, $jour, $annee, '-1');
$date_actuelle = time();
if($date_actuelle < $expire) {
    $pub = 0;
}
else
{ $pub='1'; }
}

// si le compte n'est pas gold, on affiche la pub
if($pro=='0')
{ $pub='1'; }

// si le compte est suspendu, on le d?gage
if($suspendu=='1')
{
header("location: http://www.freeheberg.com/suspendu.html");
}

// on r?cup?re les valeurs

if($pub=='1')
{

#$piece1='<div style="display: none;">';
#$piece2='</div>';
#$ListeChiffre = fopen("http://partenaires.greatsong.net/zik/free_great.php?id=$_SERVER[HTTP_HOST].$_SERVER[REQUEST_URI]","r");
#$df = fgets($ListeChiffre, 1000);
#fclose($ListeChiffre);

$tagpub="<script type=\"text/javascript\" src=\"http://78.41.233.99/~fhv3/slidein.php\"></script>
";
$tagpub2="
<!-- Tag Publicitaire Freeheberg.com -->
<script type=\"text/javascript\" src=\"http://www.veoxa.com/get_trackingcode.php?aid=63&linkid=O31&type=jscript&r=\" + document.referrer></script>
<script type=\"text/javascript\" src=\"http://www.veoxa.com/get_trackingcode.php?aid=63&sid=59&linkid=O592&type=jscript\"></script>
</body>
</html>
<!-- Pour une validation w3c, ne rajoutez pas les balises body et html a votre page. -->
<!-- FIN TAG PUBLICITAIRE -->";
} 
}

// si la pub doit ?tre ? 0, on remet bien tout ? 0
if($pub=='0')
{
$tagpub='';
$tagpub2='';
}

In any case the problem is not there.
I replaced this code :

Code: [Select]  

/* alle eventuelle Ausgaben verwerfen */
        while (ob_get_level()) {
            ob_end_clean();
        }

by this:

Code: [Select]  

/* alle eventuelle Ausgaben verwerfen */
        $buffer_level = ob_get_level();

        while (ob_get_level() > $buffer_level) {
            ob_end_clean();
        }
error_log($buffer_level , 3, $this->pmxroot . 'dynadata' . DIRECTORY_SEPARATOR . 'cache' . DIRECTORY_SEPARATOR . 'erreurs.log');

And with "firefox" the level is 2 "in the generated file
Whatever the number of levels, the server sends an error on line 155
The server crashes on this iteration, if we put a break or delete "while" the function __destruct () will not work properly
I tried with theme-cache enabled and disabled, same result.
all this concerns only firefox & IE
everything is normal for opera.



I know I should write in the section dedicated to pmx0.1.12.
but I do not know German

Hi, 

Please excuse my late reply.

Algebre has found the problem already.

My solution would be as follows:

Code: [Select]  

        /* alle eventuelle Ausgaben verwerfen */
        for ($i = 1; ($i <= 10 && ob_get_contents()); $i++) {
            ob_end_clean();
        }

The only purpose of this action is to remove any content from the output buffer. The level does not matter.
For safety, a counter is included that prevents an infinite loop.

hi
I noticed that problem is related to "zlib.output_compression = On" in php.ini.
with "Off" everything is ok. You can try it ..
With both solutions "break & for", the server sends to  the browser a file with extension "gz". but the theme is deformed (tested with firefox 3.6)


I tried with "ini_set('zlib.output_compression', 'Off');"  in the top of the file "default.css.php".
but  not work

[Andi]

Hi

we have two problems...

1.) infinite loop => solved

2.) double encoded css-output.
I think there is a bug in method compress_output() in the default.css.php and i'm just looking at the error...

try this: http://web-sniffer.net/
and check this url http://ns12.freeheberg.com/~shortym2/layout/style/default.css.php
and compare with http://www.pragmamx.org/layout/style/default.css.php
When you have not selected the option "Accept-Encoding: gzip", all is ok...

[Andi]

Hi

ok, in default.css.php is no check for zlib.output_compression off/on.
If the browser sends the 'Accept-Encoding' header to compress the data, the data are compressed twice...

The solution is, to check if zlib.output_compression is on in php.ini and if it's true, dont compress the data twice.
Add two lines in the case construct in function compress_output():

Code: [Select]  

           case !function_exists('gzcompress'):
            case ini_get('zlib.output_compression'):

Here ist the complete new function in pragmaMx 1.12 RC1:

Code: [Select]  

   private function compress_output($contents, $level = 0)
    {
        /* versuchen zu zippen? */
        $encoding = (isset($_SERVER['HTTP_ACCEPT_ENCODING'])) ? $_SERVER['HTTP_ACCEPT_ENCODING'] : '';
        $size = strlen($contents);
        switch (true) {
            case !$level:
            case $size < 2048:
            case headers_sent():
            case !function_exists('gzcompress'):
            case ini_get('zlib.output_compression'):
            case ini_get('output_handler') == 'ob_gzhandler':
                return $contents;
                break;
            case $encoding && strpos($encoding, 'x-gzip') !== false:
                header('Content-Encoding: x-gzip');
                break;
            case $encoding && strpos($encoding, 'gzip') !== false:
                header('Content-Encoding: gzip');
                break;
            default:
                return $contents;
        }
        $crc = crc32($contents);
        $out = "\x1f\x8b\x08\x00\x00\x00\x00\x00";
        $out .= substr(gzcompress($contents, $level), 0, - 4);
        $out .= pack("V", $crc) . pack("V", $size);
        return $out;
    }

changed files for pragmaMx 0.1.11 and pragmaMx 1.12 RC1 nearby...
