Bug description:proc_open: all file handles are connected to same pty
Description:
------------
If you open a program with proc_open and you connect both stdout and stderr
of that program to a pty, the same pty is used. If you use select_stream on
both stdout and stderr, select marks both as ready and you can not
distinguish which one hash data as you can read from both resources.
Test script:
---------------
$descriptorspec = array(
0 => array("pipe", "r"),
1 => array("pty"),
2 => array("pty"),
);
$proc = proc_open("programpath", $descriptorspec, $handles = array());
stream_select($read = array($handles[1], $handles[2]), $write = null,
$urgent = null, $timeout = 10);
// $read now contains $handles[1] AND $handles[2], does not matter where
the data was written to
