Bug #71448 [NEW]: declare(ticks=1) limited to scope of file makes Signal handling difficult
From: dave at atst dot io
Operating system: Linux
PHP version: 7.0Git-2016-01-25 (Git)
Package: PCNTL related
Bug Type: Bug
Bug description:declare(ticks=1) limited to scope of file makes Signal handling difficult
Description:
------------
Not sure if this is intended behaviour or fallout from other declare
directives intending to be scoped to a particular file.
The manual states:
The declare construct can also be used in the global scope, affecting
all code following it (however if the file with declare was included
then it does not affect the parent file).
I've attached a script that tries to show what I'm trying to do
automatically, but you can remove the forking and just try and ctrl-c
from your terminal.
Test script:
---------------
<?php
declare(ticks=1);
$start = time();
pcntl_signal(SIGINT, function() use ($start) {
$diff = time() - $start;
echo "SIGINT received after $diff seconds\n";
exit;
});
$id = posix_getpid();
$child = pcntl_fork();
if ($child) {
include 'inc.php';
} else {
posix_kill($id, SIGINT);
}
## inc.php
<?php
$a = 0;
$start = time();
while(time() < $start + 5) {
$a = $a + 2; # something tickable
}
Expected result:
----------------
SIGINT received after 0 seconds
Actual result:
--------------
SIGINT received after 5 seconds
