[dokuwiki] [Patch] XMLRPC listLinks support

Hi everyone,

attached is a patch that adds support for the listLinks() method
(suggested in the Wiki RPC Interface 2 specs) to DokuWikis xmlrpc
interface (and another one which fixes a little typo).

Unfortunately the docs aren't very clear about what links should be
returned - they only say local and external. With this patch
interwikilinks are treated as external links and other "links" like
windows shares or mail links are completely ignored. Changing that would
be easy though.

And another thing: I know the XMLRPC support of DokuWiki isn't high
priority, however I still like the idea. My question is - are we
strictly bound to the RPC Interface 2 specs or would it be OK to
introduce some own additional methods (only if they're actually useful
of course)?

Cheers,
    chi

[Add the Universal Wiki Edit Button to the deafault template
Andreas Gohr <andi@xxxxxxxxxxxxxx>**20071026213115
 
 The "Universal Wiki Edit Button" is a movement to make Wikis easily
 recognizable to users regardless of the used engine or template. The
 aim is to create an icon which is as easy to recognize as the now well
 known RSS icon. The hope is to spread the Wiki idea and make more people
 aware of the use of Wikis outside the scope of Wikipedia.
 
 The logo is added through a background CSS defined in UWEB.css
 
 More info about the Universal Wiki Edit Button can be found at
 http://www.aboutus.org/uweb - you may also add your thoughts about it
 there.

[X-Sendfile support for fetch.php
Andreas Gohr <andi@xxxxxxxxxxxxxx>**20071008185019
 This patch enables the use of the X-Sendfile extension offered by certain
 webservers to deliver static files after running a dynamic script. This
 combines the flexibility of a PHP file to check for authorization, caching
 and resizing with the low memory footprint and high performance of static
 file delivery of the webserver.
