Plaintext profiler
[edit]MediaWiki-Docker comes with php-tideways pre-installed, which provides support for profiling web requests and maintenance scripts. This result is the same as in production with WikimediaDebug#Plaintext_request_profile.
Add once to LocalSettings.php:
// Use ?forceprofile=1 to profile the request.
// Output is added to the end of the response (use view-source if the response is HTML).
if ( extension_loaded( 'tideways_xhprof' ) ) {
if ( isset( $_GET['forceprofile'] ) || PHP_SAPI === 'cli' ) {
$wgProfiler = [
'class' => ProfilerXhprof::class,
'flags' => TIDEWAYS_XHPROF_FLAGS_CPU | TIDEWAYS_XHPROF_FLAGS_NO_BUILTINS,
'output' => 'text',
];
}
}
Flame graph
[edit]MediaWiki-Docker does not yet come with Excimer installed. To install it one time, follow Excimer#MediaWiki-Docker installation steps.
Then, to enable it in LocalSettings, refer to the recipe at Excimer#Per-request flame graph from MediaWiki.
