#39972 [NEW]: pcntl_signal not working
From: kementeus at gmail dot com
Operating system: Debian 3.1
PHP version: 5.2.0
PHP Bug Type: PCNTL related
Bug description: pcntl_signal not working
Description:
------------
pcntl_signal is not executing the code inside the function handling of the
signal. The code example is taken from the php manual in
http://www.php.net/manual/en/ref.pcntl.php
and modified just to echo a
simple text
Reproduce code:
---------------
<?php
declare(ticks=1);
$pid = pcntl_fork();
if ($pid == -1) {
die("could not fork");
} else if ($pid) {
exit(); // we are the parent
} else {
// we are the child
}
if (!posix_setsid()) {
die("could not detach from terminal");
}
while (1) {
// do something interesting here
}
function sig_handler($signo)
{
switch ($signo) {
case SIGTERM:
// handle shutdown tasks
echo "I need to execute\n";
exit;
break;
case SIGHUP:
// handle restart tasks
break;
default:
// handle all other signals
}
}
// setup signal handlers
pcntl_signal(SIGTERM, "sig_handler");
pcntl_signal(SIGHUP, "sig_handler");
?>
Expected result:
----------------
When you send the signal SIGTERM with kill -15 PID the process should echo
the message "I need to execute" and then terminate.
Actual result:
--------------
The process terminate but doesn't echo or execute anything inside the
function handler.
