◆ doEnvironmentChecks()

Installer::doEnvironmentChecks ( )

Parameters

string[] $files

Returns: array LoadExtensionSchemaUpdates legacy hooks

References StatusValue\newGood().

◆ maybeGetWebserverPrimaryGroup()

static Installer::maybeGetWebserverPrimaryGroup ( )

static

On POSIX systems return the primary group of the webserver we're running under.

On other systems just returns null.

This is used to advice the user that he should chgrp his mw-config/data/images directory as the webserver user before he can install.

Public because SqliteInstaller needs it, and doesn't subclass Installer.

Returns: mixed

Definition at line 743 of file Installer.php.

◆ overrideConfig()

static Installer::overrideConfig ( SettingsBuilder $settings )

static

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

Parameters

SettingsBuilder $settings

Definition at line 1895 of file Installer.php.

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

◆ parse()

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

	)

Actually perform the installation.

Parameters

callable	$startCB	A callback array for the beginning of each step
callable	$endCB	A callback array for the end of each step

Returns: Status[]
