Extension:ContactPage (2.3)

Feature by Stip, includes/SpecialContact.php
(restricts legal characters in field "your name")
search replace 
			if ( !Sanitizer::validateEmail( $fromAddress ) ) {
				return [ 'invalidemailaddress' ];
			}

				return [ 'contactpage-invalidusername' ];
			}
Security Fix by Stip, includes/SpecialContact.php
(removes option of cc-mails; if this extension is activated for anonymous users, this option could be used by anyone to send mails with arbitrary content to arbitrary people, thus sending spam from your email address.)
search replace 
			'CCme' => [
				'label-message' => $this->getFormSpecificMessageKey( 'emailccme' ),
				'type' => 'check',
				'default' => $this->userOptionsLookup->getBoolOption( $user, 'ccmeonemails' ),
			],

			if ( $hookRunner->onContactForm(
				$fromUserAddress, $senderAddress, $cc_subject, $text, $this->formType, $formData )
			) {
				wfDebug( __METHOD__ . ': sending cc mail from ' . $senderAddress->toString() .
					' to ' . $fromUserAddress->toString() . "\n"
				);
				// @phan-suppress-next-line SecurityCheck-XSS UserMailer::send defaults to text/plain if passed a string
				$ccResult = UserMailer::send(
					$fromUserAddress,
					$senderAddress,
					$cc_subject,
					$text,
				);
				if ( !$ccResult->isOK() ) {
					// At this stage, the user's CC mail has failed, but their
					// original mail has succeeded. It's unlikely, but still, what to do?
					// We can either show them an error, or we can say everything was fine,
					// or we can say we sort of failed AND sort of succeeded. Of these options,
					// simply saying there was an error is probably best.
					return [ $ccResult->getMessage( 'contactpage-usermailererror', false, $language ) ];
				}
			}

Extension:DynamicPageList3 (3.6.1)

Bugfix by Stip, includes/Lister/Lister.php
(replaced deprecated system message from Extension:HitCounters)
search replace 
				'(' . wfMessage( 'hitcounters-nviews', $lang->formatNum( $article->mCounter ) )->escaped() . ')'

				'(' . wfMessage( 'hitcounters-pop-page-line', $lang->formatNum( $article->mCounter ) )->escaped() . ')'
Bugfix by Stip, includes/LST.php
(defines variable before testing it, see stackoverflow.com)
search replace 
			if ( !$end_off ) {

			$isset = array_key_exists('end_off', get_defined_vars());

			if ( !$isset ) {

Bugfix by Laskyr, includes/Query.php
(simultaneous usage of "uses", "linksfrom" or "linksto" no longer results in empty result list; see this diff)
search replace

Extension:RSS (2.25.1)

Bugfix by Stip, RSSParser.php
(self-closing img tags are filtered)
search replace 
			$ret = Sanitizer::removeSomeTags( $text, [
				'extraTags' => $extraInclude,
				'removeTags' => $extraExclude,
			] );

			$text = preg_replace( '#<img (.*?) />#i', '', $text );
			$ret = Sanitizer::removeSomeTags( $text, [
				'extraTags' => $extraInclude,
				'removeTags' => $extraExclude,
			] );

Extension:NamespaceRelations (0.3.0)

Bugfix, NamespaceRelations.php
fixes variable initialization, see MediaWiki
search replace 
$namespaceInfo = MediaWikiServices::getInstance()->getNamespaceInfo();
move to 
$namespaceInfo = MediaWikiServices::getInstance()->getNamespaceInfo();
if ( array_key_exists( $subjectNS, $this->namespacesToNamespace ) ) {

Extension:SyntaxHighlight (2.0)

Bugfix, /pygments/pygmentize
(enables extension, see MediaWiki)

change file permissions from 644 to 744 (file needs to be executable by owner)

Extension:Quiz (1.2.0)

Adjustment, /modules/ext.quiz.css
(correct/incorrect should not be colored green/red, because of Congenital red–green color blindness; ideally this should be a configuration variable)
search replace
#14866d #0000ff

Extension:Patroller (2.1)

Adjustment, /includes/specials/SpecialPatroller.php
(in our wiki there are not many edits we have to patrol, so edits which were taken but not marked as patrolled should be available faster; ideally this should be a configuration variable)
search replace 
		if ( mt_rand( 0, 499 ) == 0 ) {

		if ( mt_rand( 0, 9 ) == 0 ) {
Adjustment, /includes/specials/SpecialPatroller.php
(we do want to patrol all changes to one page, not only the last one; ideally this should be a configuration variable)
search replace 
		'rc_this_oldid = page_latest',

Extension:MultiBoilerplate (2.2.0)

Feature by Orci, includes/Hooks.php
(we only want content between pre and nowiki)
search replace 
	$editPage->textbox1 = $content;

    $content = preg_replace( '#<pre>(.*?)</pre>#ims', '$1', $content );
    $content = preg_replace( '#<nowiki>(.*?)</nowiki>#ims', '$1', $content );
	$editPage->textbox1 = $content;

Extension:Favorites (1.2)

First of all, apply this patch.

Multiple MediaWiki functions which were in use by this extensions were declared "private", and thus cannot be used by this extension anymore; quickfix: Copy the code.
