** Description changed: [Impact] - Upgrade processes that take too long will result in the service not - being restarted. + Since php7.0 still follows the compat level 9 defaults of stopping the + service at the start of an upgrade, and then starting it again at the + end of the upgrade, there is potentially a long period of the service + being stopped when there are many packages to upgrade, leading to + unwanted downtime. [Test Case] - The test case is difficult to reproduce, because it requires the upgrade - process to take a long time. + A simple apt install --reinstall will exhibit the behavior in + /var/log/syslog: + + Command: + + apt install --reinstall -y php7.0-fpm + + /var/log/syslog: + + Mar 12 13:40:17 tester systemd[1]: Reloading. + Mar 12 13:40:17 tester systemd[1]: Stopping The PHP 7.0 FastCGI Process Manager... + Mar 12 13:40:17 tester systemd[1]: Stopped The PHP 7.0 FastCGI Process Manager. + Mar 12 13:40:17 tester systemd[1]: Reloading. + Mar 12 13:40:18 tester systemd[1]: Reloading. + Mar 12 13:40:19 tester systemd[1]: Reloading. + Mar 12 13:40:19 tester systemd[1]: Reloading. + Mar 12 13:40:19 tester systemd[1]: Starting The PHP 7.0 FastCGI Process Manager... + Mar 12 13:40:19 tester systemd[1]: Started The PHP 7.0 FastCGI Process Manager. + + php-fpm is down during the entire update process. + + When upgrading to the fixed PPA, it will still shut down at the start + due to the old script being run. + + Command: + + add-apt-repository -y ppa:kstenerud/xenial-php7.0-restart-after- + upgrade-1819033 && apt update && apt dist-upgrade -y + + /var/log/syslog: + + Mar 12 13:41:40 tester systemd[1]: Reloading. + Mar 12 13:41:41 tester systemd[1]: Stopping The PHP 7.0 FastCGI Process Manager... + Mar 12 13:41:41 tester systemd[1]: Stopped The PHP 7.0 FastCGI Process Manager. + Mar 12 13:41:41 tester systemd[1]: Reloading. + Mar 12 13:41:43 tester systemd[1]: Reloading. + Mar 12 13:41:52 tester systemd[1]: Reloading. + Mar 12 13:41:52 tester systemd[1]: Reloading. + Mar 12 13:41:52 tester systemd[1]: Stopped The PHP 7.0 FastCGI Process Manager. + Mar 12 13:41:52 tester systemd[1]: Starting The PHP 7.0 FastCGI Process Manager... + Mar 12 13:41:52 tester systemd[1]: Started The PHP 7.0 FastCGI Process Manager. + + The extra "Stopped" at 13:41:52 is due to the new behavior calling + restart. + + With the new package installed, it no longer stops when beginning an + upgrade, and does a restart at the end (which php-fpm accomplishes with + a stop and start). + + Command: + + apt install --reinstall -y php7.0-fpm + + /var/log/syslog: + + Mar 12 13:43:00 tester systemd[1]: Reloading. + Mar 12 13:43:00 tester systemd[1]: Reloading. + Mar 12 13:43:01 tester systemd[1]: Reloading. + Mar 12 13:43:02 tester systemd[1]: Reloading. + Mar 12 13:43:02 tester systemd[1]: Stopping The PHP 7.0 FastCGI Process Manager... + Mar 12 13:43:02 tester systemd[1]: Stopped The PHP 7.0 FastCGI Process Manager. + Mar 12 13:43:02 tester systemd[1]: Starting The PHP 7.0 FastCGI Process Manager... + Mar 12 13:43:02 tester systemd[1]: Started The PHP 7.0 FastCGI Process Manager. + [Regression Potential] - These changes have already been applied in other releases, but were - missed on xenial for some reason. The changes are designed to address - this particular issue, and so shouldn't cause a regression. + If the service tries to load a file that has been replaced during + upgrade, but before it was restarted, it could cause a failure. However, + the service will soon be restarted anyway. + + If the restart takes too long it could fail. + [Original Description] The unattended update has launch the update of php7.0-fpm that trigger the stop of php7.0-fpm service (timestamp match that operation). The service does not restart within 10 minutes. # systemctl status php7.0-fpm ● php7.0-fpm.service - The PHP 7.0 FastCGI Process Manager - Loaded: loaded (/lib/systemd/system/php7.0-fpm.service; enabled; vendor preset: enabled) - Active: inactive (dead) since Thu 2019-03-07 15:21:00 UTC; 8min ago - Main PID: 3505 (code=exited, status=0/SUCCESS) - Status: "Processes active: 0, idle: 32, Requests: 0, slow: 0, Traffic: 0req/sec" + Loaded: loaded (/lib/systemd/system/php7.0-fpm.service; enabled; vendor preset: enabled) + Active: inactive (dead) since Thu 2019-03-07 15:21:00 UTC; 8min ago + Main PID: 3505 (code=exited, status=0/SUCCESS) + Status: "Processes active: 0, idle: 32, Requests: 0, slow: 0, Traffic: 0req/sec" Mar 07 15:14:55 xxx systemd[1]: Starting The PHP 7.0 FastCGI Process Manager...
