Bug description: pcntl_signal() does not work while waiting with socket_accept()
Configure Command: ./configure --with-imap --with-mysql --enable-sockets
--enable-pcntl
Example:
#! /usr/local/bin/php -q
<?php
error_reporting(E_ALL);
set_time_limit(0);
function sig_handler($signo) {
switch($signo) {
case SIGTERM:
// handle shutdown tasks
echo "Got SIGTERM! Closing sockets and exiting...\n";
@socket_close($msgsock);
@socket_close($sock);
exit;
break;
case SIGINT:
// handle shutdown tasks
echo "Got SIGINT! Closing sockets and exiting...\n";
@socket_close($msgsock);
@socket_close($sock);
exit;
break;
default:
// handle all other signals
}
}
$address = "127.0.0.1";
$port = 5550;
echo "Installing signal handler...\n";
if (pcntl_signal(SIGTERM, "sig_handler"))
echo "SIGTERM installed!\n";
if (pcntl_signal(SIGINT, "sig_handler"))
echo "SIGINT installed!\n";
if (($sock = socket_create(AF_INET, SOCK_STREAM, 0)) < 0) {
echo "socket_create() failed: reason: " . strerror($sock) . "\n";
exit;
}
if (($ret = socket_bind($sock, $address, $port)) < 0) {
echo "socket_bind() failed: reason: " . strerror($ret) . "\n";
exit;
}
if (($ret = socket_listen($sock, 5)) < 0) {
echo "socket_listen() failed: reason: " . strerror($ret) . "\n";
exit;
}
do {
echo "Listening...\n";
if (($msgsock = socket_accept($sock)) < 0) {
echo "socket_accept() failed: reason: " . strerror($msgsock) . "\n";
break;
}
else { socket_write($msgsock, "READY\n", 6); }
do {
break 1;
} while(true);
socket_close($msgsock);
} while(true);
socket_close($sock);
---END---
This peace of code is waiting for a socket connection
with socket_accept() and has installed
signal handlers for SIGINT and SIGTERM!
I'm expecting that catching signal SIGINT should
enter the function sig_handler() even if the script
is waiting for a connection at this moment.
That does not happen, any signal installed with
pcntl_signal() is ignored (of course not SIGKIL) while
waiting for connections with socket_accept().
The script does not enter the function sig_handler().
Kind regards
Chris
