Bug description: pcnt_signal does not work
I'm currently working with PHP-CLI in order to write a comprensive
multithread server framework, using the following PHP modules:
-PCNTL (for process forking)
-SOCKETS (for managing of sockets...)
-SYSVSEM (semaphores to syncronyze threads)
-SYSVSHM (for sharing data between threads)
-XMLRPC (the best object broking for me)
I noticed a strange behaviour of my apps when i use the PHP4.3 executable;
the following test script does not work under 4.3, while it works under
4.2.
<?php
define (PULL_TIME,"1"); //event check frequency (secs)
function usr1_handle($signal){
if ($signal==SIGUSR1)
print time() . "-Received signal!\n";
}
print "Server starting at " . time() . " ...\n";
$pid=pcntl_fork();
if ($pid==0) {
// this is the child
pcntl_signal(SIGUSR1, "usr1_handle");
sleep(5);
$i = 0;
while(true) {sleep(1);}
} else {
//this is the parent
sleep(5);
while(true) {
posix_kill($pid,SIGUSR1);
sleep(PULL_TIME);
}
}
?>
No backtrace avaible, PHP does not crash, simply do nothing.
