Bug description: Calling flush from within an output buffer prevents headers from being sent
Description:
------------
Calling flush in Apache and Apache 2 produce different results.
Within Apache after calling flush you can still send headers as the output
buffer prevents it from actually being flushed.
Within Apache 2 after calling flush you can no longer send headers even
though headers_sent still returns false.
Reproduce code:
---------------
<?php
ob_start();
echo 'test';
flush();
$newtext = ob_get_clean();
if (strpos(' ' . $_SERVER['HTTP_ACCEPT_ENCODING'], 'gzip') !== false AND
!headers_sent())
{
header('Content-Encoding: gzip');
$newtext = gzencode($newtext, 1);
}
header('Content-Length: ' . strlen($newtext));
echo $newtext;
?>
Expected result:
----------------
test
Actual result:
--------------
