Bug description: stream_copy_to_stream returns invalid values for memmapped
streams
Description:
------------
When copying from a memmapped stream, stream_copy_to_stream returns the
length of the memory-mapped segment, regardless of how much data was
actually written to the recipient stream.
Reproduce code:
---------------
<?php
class DummyWriteStream
{
function stream_open($path, $mode, $options, &$opened_path) { return
TRUE; }
function stream_write($data) { return 0; }
}
stream_wrapper_register('test2', 'DummyWriteStream');
$fp1 = fopen('/etc/hosts', 'r');
$fp2 = fopen('test2://test', 'w');
var_dump(stream_copy_to_stream($fp1, $fp2, 8192));
?>
Expected result:
----------------
int(0)
Actual result:
--------------
int(1228)
