◆ doEnvironmentChecks()

Installer::doEnvironmentChecks ( )

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

◆ 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

◆ overrideConfig()

static Installer::overrideConfig ( )

static

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

Definition at line 1689 of file Installer.php.

References $GLOBALS, and CACHE_NONE.

◆ 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

$text	String
$lineStart	Boolean

Returns: String
