Bug description: PHP writing empty files
Description:
------------
A simple upload script uploads the file, fully intact, but then a few
seconds later zero's out the file making a zero byte length file.
Reproduce code:
---------------
<?
$size = exec("ls -l $upload_item");
if ($upload_item) {
print("<br />uploading to section = $section\n");
print("<br />file name = $upload_item_name\n");
print("<br />file size = $upload_item_size bytes\n");
print("<br />file in tmp = $size\n");
if (copy ($upload_item, "./$upload_item_name")) {
print("<html><body>\n");
print("<p><b>your file was successfully
uploaded!</b></p>\n");
print("<p>\n");
print("please note your file name -
<b>$upload_item_name</b>\n");
print("<br />you will need to enter it in the
appropriate form.\n");
print("</p>\n");
print("</body></html>");
} else {
print("can't be copied - there may be another file
with this name\n");
}
}
?>
Expected result:
----------------
The file should get written to the directory specified from the form and
named the same name as the uploaded file.
Actual result:
--------------
Appropriate directories are writable by the apache user/group. Not a quota
issue. 'upload_max_filesize' is set to 55 megs. No error log is generated
as PHP has, as far as it thinks, written the file.
What happens is the file gets uploaded to /tmp (full permisssions on /tmp)
and then copied to the requested directory. I can grab a directory listing
and see it in the specified directory in whole - original size and name.
If I refresh the page again the file is zero'd out but with the original
filename.
I'm hesitant to call this a bug but having bounced this off other contacts
in the industry I am left with no choice.
