PHP Bug Type: *Directory/Filesystem functions
Bug description: File_exists and clearstatcache not working on network volume
Description:
------------
When files are saved on AFP or SMB mounted sharing, file_exists() and
clearstatcache() function are not working as expected. No problem when
files are saved on local disk. On AFP or SMB volume, file_exists
continue to return true when the file is deleted outside of PHP.
clearstatcache() function seems to have no effect.
But, if the file is deleted with the unlink() function in php,
file_exists return false.
Reproduce code:
---------------
<?
header("Content-type: text/html");
header("Expires: Mon, 26 Jul 1997 05:00:00 GMT");
header("Cache-Control: no-store, no-cache,must-revalidate");
header("Cache-Control: post-check=0, pre-check=0",false);
header("Pragma: no-cache");
clearstatcache();
$ttt="/Volumes/testdaniel/ttt.txt";
#exec("touch ".$ttt);
#...@unlink($ttt);
if(file_exists($ttt)){
echo "exists";
}else{
echo "not exists";
}
clearstatcache();
?>
Expected result:
----------------
"exists" when file really exists
"not exists" when file doesn't exists
Actual result:
--------------
"exists" even after the file was deleted
