Topic on Extension talk:Semantic Need

• General:
  • Don't use closing ?>, ever.
  • $wgExtensionMessagesFiles is supported since 1.16, this check makes no sense.
  • Don't use SMW-style localisation, it makes no sense in current MW versions.
  • Don't use comparison operators with $wgVersion, it's unreliable. Use version_compare().
  • Don't use global objects like $wgArticle, instead use RequestContext (for example, from $out).
  • Don't use superglobals like $_POST, there's WebRequest for that.
  • Don't create tables with hardcoded SQL, instead use LoadExtensionSchemaUpdates hook.
  • While I don't see an SQL injection after a brief glance, all DB code is extremely clumsy and looks like there's a lack of understanding what Database::tableName() is for: it's for building table names with prefixes (using $wgDBprefix and $wgSharedTables), not for constructing filed names. All this code will fail with non-empty table prefix.

• SNE.php:

        echo <<<EOT
To install my extension, put the following line in LocalSettings.php:
require_once( "$IP/extensions/SemanticNeed/SNE.php" );
EOT;

Double register_globals/XSS vulnerability, as it actually tries to substitute $IP.

• • What Semantics from the people means?
  • Use 'descriptionmsg' with l10n instead of 'description'.
  • No need in global $wgVersion;

• SNEBox.php:
  • Where is $sneBox defined? Looks like a register_globals vulnerability.

• SNEHooks.php:
  • Don't include scripts and styles directly, use ResourceLoader.
