Summary

0003979: is_executable is broken

Description

is_executable delegates to com.caucho.vfs.Path.isExecutable().
However, this seems to be broken, which then breaks various PHP applications that require external binaries (e.g. ImageMagick) and check if they are executable before calling them (e.g. Typo3, PHPGallery).

<?
touch("someprogram.sh");
chmod("someprogram.sh", 0700);

if( file_exists("someprogram.sh"))
{
    echo "SUCCESS";
}
else
{
    echo "FAILED: someprogram.sh should have been created";
}
echo "
";

if( is_executable("someprogram.sh") === true){
    echo "SUCCESS";
}
else
{
    echo "FAILED: someprogram.sh should be executable";
}
echo "
";

if( is_executable("/bin/bash") === true){
    echo "SUCCESS";
}
else
{
    echo "FAILED: /bin/bash should be executable";
}
echo "
";

if( is_executable("/bin/sh") === true){
    echo "SUCCESS";
}
else
{
    echo "FAILED: /bin/sh should be executable";
}
echo "
";

?>

Notes
