[00:26:42] 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] TimStarling: I'm curious about this line, https://phabricator.wikimedia.org/source/mediawiki/browse/master/includes/ForkController.php$126 [09:14:29] It looks like you added it to runJobs.php in 2009, in 59036f4d824cc9dc6b50981050ae15b6dd4df651 [09:14:55] 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] Okay I guess it's a fallback to check for signals when the PCNTL extension is missing. [10:05:33] in PHP 7.1 it's not so bad, this was written for PHP 5 [10:06:33] no it's not a fallback [10:07:09] it's for before PHP 5.3, when pcntl_signal_dispatch() was introduced [10:08:17] before PHP 5.3, the only way to check for pending signals was with declare(ticks) [10:08:36] since PHP 7.1, signal handlers can be called any time
