<?php /** * NOTE: This is an ADVANCED feature that improves performance but adds a lot * of complexity! This is only suitable for production servers because workers * won't pick up changes between when they spawn and when they handle a request. * * Phabricator spends a significant portion of its runtime loading classes * and functions, even with APC enabled. Since we have very rigidly-defined * rules about what can go in a module (specifically: no side effects), it * is safe to load all the libraries *before* we receive a request. * * Normally, SAPIs don't provide a way to do this, but with a patched PHP-FPM * SAPI you can provide a warmup file that it will execute before a request * is received. * * We're limited in what we can do here, since request information won't * exist yet, but we can load class and function definitions, which is what * we're really interested in. * * Once this file exists, the FCGI process will drop into its normal accept loop * and eventually process a request. */ function __warmup__() { $root = dirname(dirname(dirname(dirname(__FILE__)))); require_once $root.'/libphutil/src/__phutil_library_init__.php'; require_once $root.'/arcanist/src/__phutil_library_init__.php'; require_once $root.'/phabricator/src/__phutil_library_init__.php'; // Load every symbol.
