PHP Bug Type: Apache2 related
Bug description: flush sometimes don't work
Description:
------------
it works under apache1, but not on apache2
this script is used for network-speed testing
yet, i don't know if it's relative to php or apache
Reproduce code:
---------------
<?php
header("Content-Type: binary");
// while (@ob_clean());
set_time_limit(5); // may be 1
$fp = fopen("/dev/urandom");
$u = fread($fp, 1024 * 1024); // 1mb
while (1) {
echo $u;
ob_flush(); flush();
}
?>
Expected result:
----------------
under apache1, each time request to this file will download start from 0%
immediately
tested under IE & Flashget
Actual result:
--------------
but under apache2, 1st time seems ok, cancel IE download or stopped
flashget, then try again(with "Rang" header), download will not start
until script is timedout, then, start with a content-length in response
header
the process of apache2 is taking so much memory about XXmb even 1XXmb
