TYPO3 Core

I was just figuring out why my ImageMagick static binaries were not
detected by Typo3 in safe_mode php enviroment and came to supprising
results!

First of all I did chech that

exec('/usr/bin/convert');

actuall worked. And it DID! OK so I checked all other required files and
it also worked. But Typo3 still didn't found them. So i started to play
around with class.tx_install.php file and function checkImageMagick
which is responsible for detection.

Well somehow test failed here:

if (ini_get('open_basedir') ||
((at)file_exists($v)&&(at)is_file($v.$filename.$isExt)))

So I figured out that my "open_basedir" is empty so first one didn't
apply but also for example is_file($v.$filename.$isExt) returned false.

OK....So I did a little test:

echo exec('/usr/bin/whoami')."\n";
if (is_file('/usr/bin/whoami')){
echo "Exists: $v.$filename.$isExt\n";
}

DAMN I WAS SUPRISED!

whoami actually returned username so it executed, but is_file returned
FALSE! Beats me why!

Then I tried to play with:

is_dir('..') OK
is_dir('/') FALSE
is_file('/usr/bin/convert') FALSE
...

So when I commented out this "if" sentance that required either
open_basedir value or is_file Imagemagick started to WORK!

So there must be special cirmustance (everything is on linux server,
info follows) where Imagemagick detection FAILS even IM IS there!
