◆ doEnvironmentChecks()

Installer::doEnvironmentChecks ( )

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

Parameters
string$pathPath to search
array$namesArray of executable names
array | bool$versionInfoFalse 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

Parameters
array$namesArray of possible names.
array | bool$versionInfoDefault: 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 1643 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
string$text
bool$lineStart
Returns
string

A list of environment check methods called by doEnvironmentChecks().

These may output warnings using showMessage(), and/or abort the installation process by returning false.

For the WebInstaller these are only called on the Welcome page, if these methods have side-effects that should affect later page loads (as well as the generated stylesheet), use envPreps instead.
