Re: [PHP-GTK-DEV] Bug and fix for GtkScintilla on Linux | [PHP-GTK-DEV] #41875 [Bgs]: io_add_watch can't detect HUPs
From:             sebastianmarconi at gmail dot com
Operating system: Windows XP
PHP version:      5.2.3
PHP Bug Type:     PHP-GTK related
Bug description:  io_add_watch can't detect HUPs

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]
