Extension:WikiFeeds

From MediaWiki.org
Jump to: navigation, search
This extension stores its code inside a wiki page. Please be aware that MediaWiki developers do not review or keep track of extensions that put their code on the wiki.
  • These types of extensions may contain security holes that have not been noticed by a capable developer.
  • ...may use out of date interfaces and lose compatibility with new versions of MediaWiki easily as developers do not review on-wiki extension code when removing old interfaces.
  • ...and may suffer from various forms of bad coding style which could cause problems in use of the extension.
  • Additionally, it's possible that a 3rd party may alter the code and insert vulnerabilities into the code.
The developer is encouraged and invited to get commit access to MediaWiki's code repository to address this.
WARNING: the code or configuration described here poses a major security risk.

Problem: Vulnerable to SQL injection attacks, because it passes user input directly into SQL commands. This may lead to user accounts being hijacked, wiki content being compromised, private data being leaked, malware being injected, and the entire wiki content being erased, among other things.

Solution: make proper use of MediaWiki's database class instead of concatenating raw sql

Check usage (experimental)

The RSS and ATOM 0.3 feeds coming out of MediaWiki are not robust enough for all individuals. Hence the need for WikiFeeds. WikiFeeds is an alternative feed generator that outputs RSS 2.0 and ATOM 1.0 feeds. It can generate the following feeds:

  • Recent page changes
  • Newest pages
  • Recent changes by user
  • Newest pages by user
  • User watchlist (can be either public or private)
  • Recent changes for articles in a category
  • Recent changes for articles except changes made in selected category
  • Newest articles in a category
  • Newest articles except articles in selected category

WikiFeeds is present as a special page. It also inserts itself into the page view process and creates links to the available feeds. For example, when you are on a category page, the appropriate links to the per-category feeds are inserted into the HTML document for feed auto-discovery.

[edit] Demo

See http://wiki.case.edu/Special:WikiFeeds

[edit] Instructions

Most recent version of source code is available at http://opensource.case.edu/svn/MediaWikiHacks/extensions/WikiFeeds/trunk/SpecialWikiFeeds.php. (This URL seems to be down for good - try /SpecialWikiFeeds.php and /GenericXmlSyndicationFeed.php instead. No guarantee of being current.)

Installation directions are located in this source file.

Feeds can be accessed by visiting Special:WikiFeeds in your wiki. This page should show up on the special page list page.

WikiFeeds requires PHP 5 because it makes use of the PHP 5 class constants, the PHP 5 DOM functions, and the PHP SPL.

Newer versions of WikiFeeds have some of the class declarations split off in a separate file, GenericXMLSyndicationFeed.php. This file can be obtained at http://opensource.case.edu/svn/MediaWikiHacks/classes/GenericXmlSyndicationFeed/GenericXmlSyndicationFeed.php. It is recommended to use the most recent version of this file with WikiFeeds.

[edit] Unique Parameter

If you want use the unique parameter change the sql-query in line 545

replace

$sql = "SELECT rev_id AS revid, rev_page AS page, rev_user_text as user, rc_id AS rcid
      FROM $recentchanges, $revision
      WHERE rc_this_oldid=rev_id AND rev_deleted=0
      ORDER BY rev_id DESC LIMIT $count";

by

if ($unique == true) {
        $unique_sql = " AND rc_id=
                (SELECT MAX(rc_id) 
                FROM $recentchanges tmp 
                WHERE tmp.rc_cur_id=rc.rc_cur_id) ";
}
$sql = "SELECT rc_id, rev_id AS revid, rev_page AS page, rev_user_text as user, rc_id AS rcid 
        FROM $recentchanges rc, $revision 
        WHERE rc_this_oldid=rev_id AND rev_deleted=0 $unique_sql
        ORDER BY rev_id DESC LIMIT $count;";

[edit] Namespace Parameter

If you want to filter feeds by a namespace, add parameter /namespace/<namespace_name> or /namespace/<namespace_id> to URL.
