Definition at line 1546 of file Installer.php.

◆ apacheModulePresent()

static MediaWiki\Installer\Installer::apacheModulePresent ( $moduleName )

static

Returns: bool

Definition at line 1158 of file Installer.php.

protected

This is overridden by the web installer to provide the detected wgScriptPath.

Returns: array

Reimplemented in MediaWiki\Installer\WebInstaller.

Definition at line 469 of file Installer.php.

◆ dirIsExecutable()

MediaWiki\Installer\Installer::dirIsExecutable	(		$dir,
			$url )

Checks if scripts located in the given directory can be executed via the given URL.

Used only by environment checks.

Parameters

string	$dir
string	$url

Returns: bool|int|string

Reimplemented in MediaWiki\Installer\CliInstaller.

Definition at line 1103 of file Installer.php.

Definition at line 786 of file Installer.php.

◆ disableStorage()

static MediaWiki\Installer\Installer::disableStorage	(	Config	$config,
		string	$lang )

static

Reset the global service container and associated global state, disabling storage, to support pre-installation operation.

Parameters

Config	$config	Config override

◆ disableTimeLimit()

MediaWiki\Installer\Installer::disableTimeLimit ( )

Disable the time limit for execution.

Some long-running pages (Install, Upgrade) will want to do this

Definition at line 1554 of file Installer.php.

Referenced by MediaWiki\Installer\WebInstaller\execute().

◆ doEnvironmentChecks()

MediaWiki\Installer\Installer::doEnvironmentChecks ( )

Do initial checks of the PHP environment.

It's possible that this may be called under the CLI SAPI, not the SAPI that the wiki will primarily run under. In that case, the subclass should initialise variables such as wgScriptPath, before calling this function.

It can already be assumed that a supported PHP version is in use. Under the web subclass, it can also be assumed that sessions are working.

Returns: Status

◆ getVar()

MediaWiki\Installer\Installer::getVar	(		$name,
			$default = null )

Get an MW configuration variable, or internal installer configuration variable.

The defaults come from MainConfigSchema. Installer variables are typically prefixed by an underscore.

Parameters

string	$name
mixed \| null	$default

Returns: mixed

Definition at line 603 of file Installer.php.

◆ overrideConfig()

static MediaWiki\Installer\Installer::overrideConfig ( SettingsBuilder $settings )

static

Override the necessary bits of the config to run an installation.

References CACHE_NONE, and MediaWiki\Settings\SettingsBuilder\overrideConfigValues().

◆ parse()

MediaWiki\Installer\Installer::parse	(		$text,
			$lineStart = false )

Convert wikitext $text to HTML.

This is potentially error prone since many parser features require a complete installed MW database. The solution is to just not use those features when you write your messages. This appears to work well enough. Basic formatting and external links work just fine.

But in case a translator decides to throw in a "#ifexist" or internal link or whatever, this function is guarded to catch the attempted DB access and to present some fallback text.

Parameters

string	$text
bool	$lineStart

Returns: string
