Parameters:

array	$callback	A valid installation callback array, in this form: array( 'name' => 'some-unique-name', 'callback' => array( $obj, 'function' ) );
string	$findStep	the step to find. Omit to put the step at the beginning

Definition at line 1780 of file Installer.php.

static Installer::apacheModulePresent ( $ moduleName ) [static]

Checks for presence of an Apache module.

Works only if PHP is running as an Apache module, too.

Parameters:

string $moduleName Name of module to check.

Returns:: bool

Definition at line 1372 of file Installer.php.

Installer::createMainpage ( DatabaseInstaller $ installer ) [protected]

Insert Main Page with default content.

Parameters:

$installer DatabaseInstaller

Returns:: Status

Definition at line 1716 of file Installer.php.

References $res, and Status\warning().

Create the first user account, grant it sysop and bureaucrat rights.

Returns:: Status

Definition at line 1643 of file Installer.php.

Installer::dirIsExecutable	(	$	dir,
		$	url
	)

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

Installer::doEnvironmentChecks ( )

Do initial checks of the PHP environment.

Set variables according to the observed 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.

Under the web subclass, it can already be assumed that PHP 5+ is in use and that sessions are working.

Used only by environment checks.

Parameters:

string	$path	path to search
array	$names	of executable names
	$versionInfo	Boolean false or array with two members: 0 => Command to run for version check, with $1 for the full executable name 1 => String to compare the output with

If $versionInfo is not false, only executables with a version matching $versionInfo[1] will be returned.

See also:: locateExecutable()

Parameters:

$names
$versionInfo	bool

Returns:: bool|string

Definition at line 1306 of file Installer.php.

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 559 of file Installer.php.

static Installer::overrideConfig ( ) [static]

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

Definition at line 1742 of file Installer.php.

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:

$text	String
$lineStart	Boolean

Returns:: String

Definition at line 590 of file Installer.php.

Installer::performInstallation	(	$	startCB,
		$	endCB
	)

Actually perform the installation.

Parameters:

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

Returns:: Array of Status objects
