PHP version: 5.2.6RC5
PHP Bug Type: Scripting Engine problem
Bug description: File handling causes issues
Description:
------------
5.2.6RC starts behaving very strangely if you have a code that sets chmod
and chown on the new file being uploaded.
This function used to work before, and now it starts causing issues.
It seems to crash on chmod, chown, and chgrp
Reproduce code:
---------------
function handleFileUpload($uploadpath, $filenameprepend, $filesField)
{
$filename = NULL;
if (isset($_FILES[$filesField]['name']) &&
!empty($_FILES[$filesField]['name']) )
{
$pinfo = pathinfo($_FILES[$filesField]['name']);
$extn = strtolower($pinfo['extension']);
$uploaddir = $uploadpath;
$filename = $filenameprepend . '.' . $extn;
$uploadfile = $uploaddir . $filename;
move_uploaded_file($_FILES[$filesField]['tmp_name'],
$uploadfile);
sleep(2);
chmod($uploadfile,"0666");
chown($uploadfile,$this->getSystemUser());
chgrp($uploadfile,$this->getSystemGroup());
}
return $filename;
}
Expected result:
----------------
The above code block worked on 5.2.4. I believe this is being caused by
Fixed move_uploaded_file() to always set file permissions of resulting file
according to UMASK. (Andrew Sitnikov)
It should set the mode and ownership and group IF the user is explicitly
coding it in.
Actual result:
--------------
Errors like the following show up
Warning: chown() [function.chown]: Operation not permitted in
/home/chinajapantraders/www/scripts/generalfunctions.php on line 43
Warning: chgrp() [function.chgrp]: Operation not permitted in
/home/chinajapantraders/www/scripts/generalfunctions.php on line 44
chmod doesnt give an error, however, the modes arent being set correctly
either. The modes show up as : --w--wx-wT if i set it as 0666 as mentioned
above.
