Description

Two major issues:
  • bad formatting on the API documentation page - every single string / text is displayed as a link resulting in limited readability
  • unable to find any external links through http://rbose.org/wiki/Special:LinkSearch - the list of supported protocols is empty

Even if protocols have been defined in config and properly parsed on wiki pages, the reported problems were observed.

According to https://secure.wikimedia.org/wikipedia/mediawiki/wiki/Manual:$wgUrlProtocols allowed values are:
  • array of strings
  • string containing a regular expression before 1.6.0

Therefor a change from:

$wgUrlProtocols = 'http:\/\/|https:\/\/|ftp:\/\/|irc:\/\/|gopher:\/\/|news:|mailto:|mumble:\/\/|magnet:\?';

to:

$wgUrlProtocols = array('http://',
                        'https://',
                        'ftp://',
                        'irc://',
                        'gopher://',
                        'news:',
                        'mailto:',
                        'mumble://',
                        'magnet:',
);

solved the problems.

Documented because I haven't found this solution and these bugs reported on the web, hopefully it will help someone.

I discovered that the table of external links was screwed up somehow. rebuildall.php and refreshLinks.php did not work. Many links which did not show up through api and Special:LinkSearch. They were present in el_to column but their value in el_index was set strangely to './'. Somehow I'm not able to edit values in that table.

To fix the externallinks table:
  • set the database to read only mode in wiki configuration file
  • backup externallinks table
  • drop the externalinks table
  • created and empty version of externalinks table
  • launched refreshLinks.php (you may need to disable some plugins if you see errors, like gnuplot, graphviz, etc.)

That finally worked!
