New Comment:
all errors happen here ---> $ret = copy($out, $dest);
should be:
all errors happen here ---> $ret = fs_copy($out, $dest);
and /home/platform/fs_unix.php line 15
is just:
$result = copy($source, $dest);

Description:
------------
I have a script which unzip an uploaded ZIP file (contains image files)
into a temp directory, "/dev/shm/tmp" (tmpfs for speed, I tried to use
/tmp but still got the problem), which is owned by "nobody" and 777 in
permission.
The script will then process the unzipped image files, one by one, by
calling an resize_image() function.
The resize_image() function will try to resize the image, then copy the
resized image to somewhere else.
The script works most of the time, but sometime, it failed with
something like:
[04-Jun-2005 17:19:47] PHP Warning: copy(/dev/shm/tmp/00800040.jpg):
failed to open stream: Permission denied in /home/platform/fs_unix.php
on line 15
[04-Jun-2005 17:19:48] PHP Warning: copy(/dev/shm/tmp/00800041.jpg):
failed to open stream: Permission denied in /home/platform/fs_unix.php
on line 15
[04-Jun-2005 17:19:49] PHP Warning: copy(/dev/shm/tmp/00800042.jpg):
failed to open stream: Permission denied in /home/platform/fs_unix.php
on line 15
[04-Jun-2005 17:19:50] PHP Warning: copy(/dev/shm/tmp/00800043.jpg):
failed to open stream: Permission denied in /home/platform/fs_unix.php
on line 15
.....
when the error happens, all of the files insize the same zip file will
result in same error.
I don't really know what's wrong since the scipt sometime works,
sometime doesn't
Reproduce code:
---------------
util.php, $src will == $dest, $target is target size
function resize_image($src, $dest, $target) {
if (!strcmp($src,$dest)) {
$useTemp = true;
$out = "$dest.tmp";
}
else {
$out = $dest;
$useTemp = false;
}
/* resize xxx.jpg to xxx.jpg.tmp at the same directory */
$err = exec_wrapper("convert -quality 85 -size ${target}x${target} $src
$out");
if (file_exists("$out") && filesize("$out") > 0) {
if ($useTemp) {
//// copy back xxx.jpg.tmp to xxx.jpg ////
all errors happen here ---> $ret = copy($out, $dest);
unlink($out);
if (!$ret){
return 0;
}
return 1;
}
} else {
return 0;
}
}
Expected result:
----------------
fs_copy() should not be failed with "permission denied" error
Actual result:
--------------
something failed with permission error
