<?php
/**
 * The setup for all MediaWiki processes (both web-based and CLI).
 *
 * The entry point (such as WebStart.php and doMaintenance.php) has these responsibilities:
 * - The entry point MUST:
 *   - define the 'MEDIAWIKI' constant.
 * - The entry point SHOULD:
 *   - define the 'MW_ENTRY_POINT' constant.
 *   - display an error if MW_CONFIG_CALLBACK is not defined and the
 *     file specified in MW_CONFIG_FILE (or the LocalSettings.php default location)
 *     does not exist. The error should either be sent before and instead
 *     of the Setup.php inclusion, or (if it needs classes and dependencies
 *     from core) the error can be displayed via a MW_CONFIG_CALLBACK,
 *     which must then abort the process to prevent the rest of Setup.php
 *     from executing.
 *
 * This file does:
 * - run-time environment checks,
 * - define MW_INSTALL_PATH, $IP, and $wgBaseDirectory,
 * - load autoloaders, constants, default settings, and global functions,
 * - load the site configuration (e.g. LocalSettings.php),
 * - load the enabled extensions (via ExtensionRegistry),
 * - trivial expansion of site configuration defaults and shortcuts
 *   (no calls to MediaWikiServices or other parts of MediaWiki),
 * - initialization of:
 *   - PHP run-time (setlocale, memory limit, default date timezone)
 *   - the debug logger (MWDebug)
 *   - the service container (MediaWikiServices)
 *   - the exception handler (MWExceptionHandler)
 *   - the session manager (SessionManager)
 * - complex expansion of site configuration defaults (those that require
 *   calling into MediaWikiServices, global functions, or other classes.).
