[00:26:42] <ST47>	 Okay, I'm lost now. I have a private wiki with PluggableAuth and the Language Extension Bundle. In my Preferences, there's no way to customize my signature. The "New signature:" field label is displayed, but no actual field is. Any idea how I can find out why not?
[09:14:07] <awight>	 TimStarling: I'm curious about this line, https://phabricator.wikimedia.org/source/mediawiki/browse/master/includes/ForkController.php$126
[09:14:29] <awight>	 It looks like you added it to runJobs.php in 2009, in 59036f4d824cc9dc6b50981050ae15b6dd4df651
[09:14:55] <awight>	 Doesn't that cause an extra instruction for every interpreted line?
[09:17:10] * awight shudders, reading about PHP's signal handling
[09:19:56] <awight>	 Okay I guess it's a fallback to check for signals when the PCNTL extension is missing.
[10:05:33] <TimStarling>	 in PHP 7.1 it's not so bad, this was written for PHP 5
[10:06:33] <TimStarling>	 no it's not a fallback
[10:07:09] <TimStarling>	 it's for before PHP 5.3, when pcntl_signal_dispatch() was introduced
[10:08:17] <TimStarling>	 before PHP 5.3, the only way to check for pending signals was with declare(ticks)
[10:08:36] <TimStarling>	 since PHP 7.1, signal handlers can be called any time
