Bug #64770 [NEW]: stream_select() fails with pipes from proc_open()
From: ab
Operating system: Windows x64
PHP version: 5.5Git-2013-05-03 (Git)
Package: Streams related
Bug Type: Bug
Bug description:stream_select() fails with pipes from proc_open()
Description:
------------
When proc_open() delivers the pipes for a process, an attempt to
stream_select on them fails. However using stream_get_contents() on the
same readable pipes (like stdout) works fine. This bug currently prevents
the phpt test suite from running on windows x64.
Test script:
---------------
<?php
$descs = array(
0 => array('pipe', 'r'), // stdin
1 => array('pipe', 'w'), // stdout
2 => array('pipe', 'w'), // strerr
);
$other_opts = array('suppress_errors' => false, 'binary_pipes' => true);
$p = proc_open('dir', $descs, $pipes, '.', NULL, $other_opts);
var_dump($p);
if (is_resource($p)) {
$data = '';
while (1) {
$n = stream_select($pipes, $w = NULL, $e = NULL, 300);
var_dump($n);
if ($n === false) {
echo "no streams \n";
break;
} else if ($n === 0) {
echo "process timed out\n";
proc_terminate($p, 9);
break;
} else if ($n > 0) {
$line = fread($pipes[1], 8192);
if (strlen($line) == 0) {
/* EOF */
break;
}
$data .= $line;
}
}
var_dump(strlen($data));
$ret = proc_close($p);
var_dump($ret);
}
?>

Actual result:
