Using Windows binary with Gtk+ 2.10 with GTK::IO_HUP | GTK::IO_IN the
script doesn't hang anymore but shows the content partially. For example
sometimes only the first lines, others only the last, and regularly
there's no output at all.

If you use the second argument of the watch :

function hupin($pipe, $condition)

Only IO_IN (integer 1) is fired, in few cases both IO_IN| IO_HUP
(integer 17). In previous version (2.0.0 alpha) IO_HUP worked
correctly.

This only is a toy example, but my main application uses this behavior
avoiding the 'busy-wait' effect in several long running tasks (wrapping
svn commands for example), and currently it's loosing functionality in
Windows.

You need to add code to detect HUP | IN - hup is never being called
separately so the second watch is never being fired

<?php

function out($pipe) {
       echo "STDOUT\n";
       echo stream_get_contents($pipe);
}

function hupin($pipe){
       echo "STDOUT\n";
       echo stream_get_contents($pipe);
       echo "HUP\n";
       Gtk::main_quit();
       return false;
}

function hup($pipe){
       echo "HUP\n";
       Gtk::main_quit();
       return false;
}

$pipes = null;
$descriptor = array(
       0 =>  array("pipe", "r"),  // stdin
       1 =>  array("pipe", "w"),  // stdout is a pipe that the child
will write to
       2 =>  array("pipe", "w")   // stderr
);
$cmd = 'dir';
$p = proc_open($cmd, $descriptor, $pipes);
Gtk::io_add_watch($pipes[1],GTK::IO_IN, 'out');
Gtk::io_add_watch($pipes[1],GTK::IO_HUP, 'hup');
Gtk::io_add_watch($pipes[1],GTK::IO_HUP | GTK::IO_IN, 'hupin');

Gtk::main();
echo "EXIT\n";
fclose($pipes[0]);
fclose($pipes[1]);
fclose($pipes[2]);
?>

Description:
------------
It seems that Gtk::io_add_watch
can't detect HUP conditions using
beta Windows binary with Gtk+ 2.10.

In some cases the only workaround that I've found is to look the
process status info [1] in the STDOUT callback (sometimes it sends IO_IN
signals constantly), but randomly losses some information.


[1]
<?php

$status = proc_get_status($proc_id);
if (! $status['running']) {
	$this-> io_hup($pipe);
}	

?> 

Reproduce code:
---------------
<?php

function out($pipe) {
       echo "STDOUT\n";
       echo stream_get_contents($pipe);
}

function hup($pipe){
       echo "HUP\n";
       Gtk::main_quit();
       return false;
}


$pipes = null;
$descriptor = array(
       0 =>  array("pipe", "r"),  // stdin
       1 =>  array("pipe", "w"),  // stdout is a pipe that the child
will write to
       2 =>  array("pipe", "w")   // stderr
);
$cmd = 'dir';
$p = proc_open($cmd, $descriptor, $pipes);
Gtk::io_add_watch($pipes[1],Gtk::IO_IN, 'out');
Gtk::io_add_watch($pipes[1],Gtk::IO_HUP, 'hup');

Gtk::main();
echo "EXIT\n";
fclose($pipes[0]);
fclose($pipes[1]);
fclose($pipes[2]);

?> 

Expected result:
----------------
STDOUT
[Dir contents]
HUP
EXIT

Actual result:
--------------
STDOUT
[The script hangs]
