[FIX] Problems on windows servers

[bsemf]

Hi,

First I wanna say: Great Chat, I've never seen such a nice ajax chat.

My Problem:
I'm running a windows 2003 server with apache 2.2 and php5.
Still 0.6 makes problems with the RelativePath function.

I just wanted to post that problem, I don't know you already know this bug.

[phpfreechat]

Could you post the result of this little script ?

Code: Select all

<?php
 echo "<pre>"; print_r($_SERVER); echo "</pre>";
?>

it will help to understand why the relative path is wrong.

Moreover, do you have :
1. URL RewritingRules for the chat in your Apache configuration ?
2. Do you have a CGI installation of php ?
(I know pfc makes problems on such configs)

Here you are:

I have ModRewrite ON but I don't use it within the chat.
My PHP is running as mod_php for apache

[phpfreechat]

Code: Select all

[SCRIPT_FILENAME] => C:/Programme/xampp/htdocs/test.php

Seems to be correct.

Could you copy/paste the error message you get ?

[bsemf]

My error I get with demo1:
Fatal error: Maximum execution time of 60 seconds exceeded in C:Programmexampphtdocsphpfreechat-0.6srcphpfreechattools.class.php on line 40

I think the while expression causes that error

[phpfreechat]

Line 40 is :

Code: Select all

if(session_id() == "") session_start();

it seems you have a problem with your sessions.

Does session_id and session_start exists on your system ?

try this script to know:

Code: Select all

<?php
if (!function_exists("session_id")) echo "session_id doesn't exists!";
if (!function_exists("session_start")) echo "session_start doesn't exists!";
?>

Maybe there is a mistake in your php.ini config about sessions ?

[bsemf]

Sessions are all fine, I use a phpBB2 Forum and there are no problems, the problem is the while clause in this function

Code: Select all

function RelativePath($p1, $p2)
  {
    if (is_file($p1)) $p1 = dirname($p1);
    if (is_file($p2)) $p2 = dirname($p2);
    // using realpath function is necessary to resolve symbolic links
    $p1 = realpath(phpFreeChatTools::CleanPath($p1));
    $p2 = realpath(phpFreeChatTools::CleanPath($p2));
    $res = "";
    while( $p1 != "" && $p1 != "/" && strpos($p2, $p1) === FALSE)
    {
      $res .= "../";
      $p1 = dirname($p1);
    }
    $p2 = substr($p2, strlen($p1)+1, strlen($p2)-strlen($p1));
    $res .= $p2;
    // remove the last "/"
    if (preg_match("/.*/$/", $res)) $res = preg_replace("/(.*)//","$1",$res);
    // if rootpath is empty replace it by "." to avoide url starting with "/"
    if ($res == "") $res = ".";
    return $res;
  }

I tried to replace the while clause with serveral IF ones, and it didn't work either but the script finished.

Then this error comes:

Code: Select all

Fatal error: The xajax uncompressed Javascript file could not be found in the ./data/public//xajax_js folder. Error in C:Programmexampphtdocsphpfreechat-0.6libxajax_0.2_stablexajax.inc.php on line 557

Ok thanks!
I based this method on unix standard : with "/" separator.

It will be hard for me to debug because I don't have a windows platform...

I can give you ftp access just write me an e-mail.

bsemfger <at> aim.com

btw: Are you planning to make this chat multi-language enabled?? With language files? I could translate them an the Homepage into german, just please give the files or tell me where I do find them.

I don't have time for now but I will contact you when I have a minute.

Yes, this is exactly on what I'm working today.
Wait for 0.7 release it will include multi-language labels.

About the homepage (overview, install, customize) I really interested by any translations.

I now manged to fix this bug

Code: Select all

function RelativePath($p1, $p2)
  {
    if (is_file($p1)) $p1 = dirname($p1);
    if (is_file($p2)) $p2 = dirname($p2);
    // using realpath function is necessary to resolve symbolic links
    $p1 = realpath(phpFreeChatTools::CleanPath($p1));
      $p2 = realpath(phpFreeChatTools::CleanPath($p2));
    $res = "";
    while( $p1 != "" && $p1 != "/" && strpos($p2, $p1) === FALSE)
    {
      $res .= "../";
      $p1 = dirname($p1);
    }
    $p2 = (isset($_SERVER["WINDIR"])) ? str_replace("\","/",substr($p2, strlen($p1)+1, strlen($p2)-strlen($p1))) : substr($p2, strlen($p1)+1, strlen($p2)-strlen($p1));
    $res .= $p2;echo "<br>n";
    // remove the last "/"
    if (preg_match("/.*/$/", $res)) $res = preg_replace("/(.*)//","$1",$res);
    // if rootpath is empty replace it by "." to avoide url starting with "/"
    if ($res == "") $res = ".";
    return $res;
  }

  function CleanPath($path)
  {
    $result = array();
    // $pathA = preg_split('/[/\]/', $path);
    $pathA = (isset($_SERVER["WINDIR"])) ? explode('\', $path) : explode('/', $path);
    if (!$pathA[0])
      $result[] = '';
    foreach ($pathA AS $key => $dir) {
      if ($dir == '..') {
        if (end($result) == '..') {
          $result[] = '..';
        } elseif (!array_pop($result)) {
          $result[] = '..';
        }
      } elseif ($dir && $dir != '.') {
        $result[] = $dir;
      }
    }
    if (!end($pathA))
      $result[] = '';
    return implode('/', $result);
  }

And in the pfc.class.php
Replace line 81 with

Code: Select all

$xajax_js = (isset($_SERVER["WINDIR"])) ? phpFreeChatTools::RelativePath(phpFreeChatTools::GetScriptFilename(), $c->data_public."/") : $c->rootpath.'/data/public/';
