Description

On Windows-Systems with safe_mode = On the exec()-Command for ImageMagick/GraphicsMagick fails.
It's not possible to run TYPO3 correct with IM e.g. GM when safe_mode is On.

Same Problem in TYPO3 4.0.2 and 4.0.4

Tested with PHP 4.4.4 and PHP 5.0.2

Affected File: t3lib/class.t3lib_div.php

Function: imageMagickCommand

Solution: Unset the path when on Windows and safe_mode = On, see the Code-Snippet below

function imageMagickCommand($command, $parameters, $path='')    {
        $gfxConf = $GLOBALS['TYPO3_CONF_VARS']['GFX'];
        $isExt = (TYPO3_OS=='WIN' ? '.exe' : '');
        $switchCompositeParameters=false;
if(!$path)    { $path = $gfxConf['im_path']; }
>     if ((TYPO3_OS=='WIN') and (ini_get('safe_mode')==1) ) {
>          $path = '';
->     }

Put IM into the safe_mode_exec_dir directory. See http://www.php.net/manual/en/features.safe-mode.php.

Hi Martin,

I have forgotten to say that it happens on Windows XP.
I have no Windows 2003 Server to test this.

GM resides in the safe_mode_exec_dir!
Only the exec()-Command has to be changed without leading path.

My Settings:
safe_mode On
safe_mode_exec_dir /Programme/TYPO3_4.0.2/GraphicsMagick/

With my Hack:
exec('gm.exe identify -version') works fine !

Without my Hack:
exec('/Programme/TYPO3_4.0.2/GraphicsMagick/gm.exe identify -version') fails !

regards, Andreas

The issue is very old, does this issue exists in newer versions of TYPO3 CMS (4.5 or 6.1)?

safe_mode is deprecated in PHP - or even already removed. Anyway: Current versions of TYPO3 do not support safe_mode=On anymore. Without safe_mode ImageMagick/GraphicsMagick are generally working.
