Bug #77603 [NEW]: Unexpected behavior with reloading php-fpm and sleep method

From: aliborhani1 at gmail dot com Operating system: Ubuntu 18.04.2 LTS PHP version: 7.3.2 Package: FPM related Bug Type: Bug Bug description:Unexpected behavior with reloading php-fpm and sleep method Description: ------------ When I use sleep() method in my script and set process_control_timeout to 20s in php-fpm.conf, I see unexpected behavior when I reload the php-fpm. It seems it doesn't respect the sleep's argument (e.g. 10 seconds) and wakes up the script too early. However, when I use exec('sleep 10') instead, it works correctly: ``` [02-11-2019 11:39:15] before sleep [02-11-2019 11:39:25] after sleep [02-11-2019 11:39:25] after echo ``` PHP Version: PHP 7.3.2-3+ubuntu18.04.1+deb.sury.org+1 (cli) (built: Feb 8 2019 15:43:57) ( NTS ) Webserver: Nginx - using unix socket Test script: --------------- <?php slog("before sleep"); // this works: // exec('sleep 10'); // but, this doesn't work: sleep(10); slog("after sleep"); echo "Done!" . PHP_EOL; slog("after echo"); function slog(string $text) { $text = '[' . strftime("%m-%d-%Y %H:%M:%S") . '] ' . $text . PHP_EOL; file_put_contents(__DIR__ .
