Detailed Description

This class encapsulates bootstrap related methods. It is required directly as the very first thing in entry scripts and used to define all base things like constants and paths and so on.

Most methods in this class have dependencies to each other. They can not be called in arbitrary order. The methods are ordered top down, so a method at the beginning has lower dependencies than a method further down. Do not fiddle with the load order in own scripts except you know exactly what you are doing!

Member Function Documentation

◆ baseSetup()

static TYPO3\CMS\Core\Core\Bootstrap::baseSetup ( )

static

Run the base setup that checks server environment, determines paths, populates base files and sets common configuration.

Script execution will be aborted if something fails here.

Exceptions

◆ checkEncryptionKey()

static TYPO3\CMS\Core\Core\Bootstrap::checkEncryptionKey ( )

staticprotected

Check if a configuration key has been configured

Definition at line 527 of file Bootstrap.php.

References $GLOBALS.

◆ checkIfEssentialConfigurationExists()

static bool TYPO3\CMS\Core\Core\Bootstrap::checkIfEssentialConfigurationExists ( ConfigurationManager $configurationManager )

staticprotected

checks if LocalConfiguration.php or PackageStates.php is missing, used to see if a redirect to the install tool is needed

Parameters

ConfigurationManager $configurationManager

Returns: ‪bool TRUE when the essential configuration is available, otherwise FALSE

This is not a public API method, do not use in own extensions

Definition at line 228 of file Bootstrap.php.

◆ createCache()

static FrontendInterface TYPO3\CMS\Core\Core\Bootstrap::createCache	(	string	$identifier,
		bool	$disableCaching = `false`
	)

static

Instantiates an early cache instance

Creates a cache instances independently from the CacheManager. The is used to create the core cache during early bootstrap when the CacheManager is not yet available (i.e. configuration is not yet loaded).

Parameters

string	$identifier
bool	$disableCaching

Returns: ‪FrontendInterface

Definition at line 321 of file Bootstrap.php.

References $GLOBALS.

◆ createConfigurationManager()

static ConfigurationManager TYPO3\CMS\Core\Core\Bootstrap::createConfigurationManager ( )

static

We need an early instance of the configuration manager. Since makeInstance relies on the object configuration, we create it here with new instead.

Returns: ‪ConfigurationManager

Definition at line 292 of file Bootstrap.php.

◆ createPackageManager()

static PackageManager TYPO3\CMS\Core\Core\Bootstrap::createPackageManager	(		$packageManagerClassName,
		FrontendInterface	$coreCache
	)

static

Initializes the package system and loads the package configuration and settings provided by the packages.

Parameters

string	$packageManagerClassName	‪Define an alternative package manager implementation (usually for the installer)
FrontendInterface	$coreCache

Returns: ‪PackageManager

This is not a public API method, do not use in own extensions

Definition at line 243 of file Bootstrap.php.

◆ init()

static ContainerInterface TYPO3\CMS\Core\Core\Bootstrap::init	(	ClassLoader	$classLoader,
		bool	$failsafe = `false`
	)

static

Bootstrap TYPO3 and return a Container that may be used to initialize an Application class.

Parameters

ClassLoader	$classLoader	‪an instance of the class loader
bool	$failsafe	‪true if no caching and a failsafe package manager should be used

Returns: ‪ContainerInterface

◆ initializeBackendAuthentication()

static TYPO3\CMS\Core\Core\Bootstrap::initializeBackendAuthentication ( $proceedIfNoUserIsLoggedIn = false )

static

Initializes and ensures authenticated access

This is not a public API method, do not use in own extensions

Parameters

bool $proceedIfNoUserIsLoggedIn ‪if set to TRUE, no forced redirect to the login page will be done

Definition at line 607 of file Bootstrap.php.

References $GLOBALS.

◆ initializeBackendRouter()

static TYPO3\CMS\Core\Core\Bootstrap::initializeBackendRouter ( )

static

Initialize the Routing for the TYPO3 Backend Loads all routes registered inside all packages and stores them inside the Router

This is not a public API method, do not use in own extensions

Deprecated:: ‪this does not do anything anymore, as TYPO3's dependency injection already loads the routes on demand.

Definition at line 579 of file Bootstrap.php.

◆ initializeBackendUser()

static TYPO3\CMS\Core\Core\Bootstrap::initializeBackendUser ( $className = BackendUserAuthentication::class )

static

Initialize backend user object in globals

Parameters

string $className ‪usually \TYPO3\CMS\Core\Authentication\BackendUserAuthentication::class but can be used for CLI

◆ initializeBasicErrorReporting()

static TYPO3\CMS\Core\Core\Bootstrap::initializeBasicErrorReporting ( )

staticprotected

Initialize basic error reporting.

There are a lot of extensions that have no strict / notice / deprecated free ext_localconf or ext_tables. Since the final error reporting must be set up after those extension files are read, a default configuration is needed to suppress error reporting meanwhile during further bootstrap.

Please note: if you comment out this code, TYPO3 would never set any error reporting which would need to have TYPO3 Core and ALL used extensions to be notice free and deprecation free. However, commenting this out and running functional and acceptance tests shows what needs to be done to make TYPO3 Core mostly notice-free (unit tests do not execute this code here).
