Bug description: fgets causes memory leaks
Try this script (tested on windows, linux and open BSD(:
<?php
set_time_limit(0);
while (1) {
unset($page);
print "iteration ". ++$c;
$fp = fsockopen("google.com", 80);
fwrite($fp, "GET / HTTP/1.0\r\n\r\n");
while (!feof($fp)) {
$page .= fgets($fp, 1000);
}
}
?>
Run it with top or whatever running and watch the memory usage go up and up (not
especially quickly because the page is small, but in certain situations I've had
memory chewage of 1mb/minute).
Now cf.
<?php
set_time_limit(0);
while (1) {
unset($page);
print "iteration ". ++$c;
$fp = fsockopen("google.com", 80);
fwrite($fp, "GET / HTTP/1.0\r\n\r\n");
while (!feof($fp)) {
$page .= fread($fp, 1000);
}
}
?>
Memory usage remains constant here.
[This meant I had to rewrite the readLine method in Net_Socket to use fread instead of
fgets.]
