It seems that fread command leaks memory when data is
read from a socket. It does not leak memory if it reads
from open file descriptor. The speed of the process increse is as fast
as the data flow, i.e. all bytes
which are read leaks!
Here is a program that shows the problem. We have a file
server in the port 9229. When connection is opened there
and about 250 MB zip file is requested, the process dies
after it has received 8 MB of data. If the file is read
from an open file, the process size does not increse at
all, and it works perfectly.
<?php
$len=248532882;
header("Content-Type: application/octet-stream");
header("Content-Disposition: attachment; filename=file.zip");
header("Content-Length: $len");
$pkg_size=1024;
if(1) {
$sock=fsockopen("localhost", 9229) or die ("Cannot open socket");
fputs($sock, "GET file.zip\r\n");
}
else {
$sock=fopen("file.zip", "r");
}
while(!feof($sock)) {
$recv_amount=(($len > $pkg_size) ? ($pkg_size): ($len));
print fread($sock, $recv_amount);
$len=$len-$recv_amount;
if($len<1) break;
}
flush();
fclose($sock);
?>
Here is the configuration command of PHP 4.1.2 we are
using, as reported by the phpinfo().
'./configure' '--with-apache=../apache_1.3.23'
'--with-ldap=/data/usr/iPlanet/ldapcsdk414' '--prefix=/data'
'--enable-memory-limit'
