Bootstrap

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!

Methods

baseSetup()

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

public static baseSetup() : mixed

Script execution will be aborted if something fails here.

Internal

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

Tags
throws
RuntimeException

when TYPO3_REQUESTTYPE was not set before, setRequestType() needs to be called before

checkIfEssentialConfigurationExists()

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

public static checkIfEssentialConfigurationExists(ConfigurationManager $configurationManager) : bool
Parameters
$configurationManager : ConfigurationManager
Internal

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

Return values
bool —

TRUE when the essential configuration is available, otherwise FALSE

createCache()

Instantiates an early cache instance

public static createCache(string $identifier[, bool $disableCaching = false ]) : FrontendInterface

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
$identifier : string
$disableCaching : bool = false
Internal
Return values
FrontendInterface

createConfigurationManager()

We need an early instance of the configuration manager.

public static createConfigurationManager() : ConfigurationManager

Since makeInstance relies on the object configuration, we create it here with new instead.

Return values
ConfigurationManager

createPackageManager()

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

public static createPackageManager(string $packageManagerClassName, PackageCacheInterface $packageCache) : PackageManager
Parameters
$packageManagerClassName : string

Define an alternative package manager implementation (usually for the installer)

$packageCache : PackageCacheInterface
Internal

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

Return values
PackageManager

init()

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

public static init(ClassLoader $classLoader[, bool $failsafe = false ]) : ContainerInterface
Parameters
$classLoader : ClassLoader

an instance of the class loader

$failsafe : bool = false

true if no caching and a failsafe package manager should be used

Return values
ContainerInterface

initializeBackendAuthentication()

Initializes and ensures authenticated access

public static initializeBackendAuthentication([bool $proceedIfNoUserIsLoggedIn = false ]) : mixed
Parameters
$proceedIfNoUserIsLoggedIn : bool = false

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

Internal

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

initializeBackendUser()

Initialize backend user object in globals

public static initializeBackendUser([string $className = BackendUserAuthentication::class ][, ServerRequestInterface|null $request = null ]) : mixed
Parameters
$className : string = BackendUserAuthentication::class

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

$request : ServerRequestInterface|null = null
Internal

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

initializeClassLoader()

Sets the class loader to the bootstrap

loadBaseTca()

Load $TCA

public static loadBaseTca([bool $allowCaching = true ][, FrontendInterface|null $coreCache = null ]) : mixed

Parameters
$allowCaching : bool = true

True, if loading TCA from cache is allowed

$coreCache : FrontendInterface|null = null
Internal

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

loadExtTables()

Load ext_tables and friends.
