on php5.0.0,
I would like to have php core team opinion on this :
- cli version loose stdin when using pcntl_signal, but it's NOT possible to
recover it
- cgi version loose stdin when using pcntl_signal, and it's possible to
recover it
If it's not a bug, i just would like to understand ;)
Little test script :
<?php
// Use this little test script like that :
// while :; do date; sleep 1; done | php ./test2.php
function sig_handler($signo) {
global $stdin;
print "Caught SIGALM...\n";
pcntl_alarm(3);
// For explain line below, see http://bugs.php.net/bug.php?id=26838
// "signals make STDIN become EOF"
$stdin = fopen("php://stdin", 'r') or die('1');
}
print "Installing signal handler...\n";
pcntl_signal(SIGALRM, "sig_handler");
print "Generating signal SIGTERM to self...\n";
declare(ticks=1);
pcntl_alarm(3);
$stdin = fopen("php://stdin", 'r') or die('1');
while (!feof($stdin)) {
echo fgets($stdin);
}
print "Done\n"
/*
// Using PHP-5.0.0(cgi) --enable-cgi --enable-fastcgi, $stdin is recover
when sig_handler called
// WORK
