Detailed Description

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, and $IP,
• 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.).

Variable Documentation

$dynamicDefaults

if (defined('MW_SETUP_CALLBACK')) $dynamicDefaults = new DynamicDefaultValues( $wgSettings->getConfigSchema() )

Customization point after most things are loaded (constants, functions, classes, LocalSettings.

Note that this runs before extensions are registered, and before most singletons become available, and before MediaWikiServices is initialized.

$IP

if(!defined( 'MEDIAWIKI')) if (!defined('MW_ENTRY_POINT')) $IP = wfDetectInstallPath()

Environment checks.

These are inline checks done before we include any source files, and thus these conditions may be assumed by all source code.

Access: internal

For read-only use in LocalSettings.php.

Source code should use the MW_INSTALL_PATH constant instead (T56483).

$wgCommandLineMode

if (!interface_exists(LoggerInterface::class)) $wgCommandLineMode = MW_ENTRY_POINT === 'cli'

Pre-config setup: Before loading LocalSettings.php.

These are changes and additions to runtime that don't vary on site configuration.
