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

Used only by environment checks.

Parameters

Definition at line 1818 of file Installer.php.

Referenced by WebInstaller\execute().

◆ doEnvironmentChecks()

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.

◆ 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 ( )

References $GLOBALS, CACHE_NONE, and class.

◆ 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.
