24 * LIBRARY USED - POSSIBLE PROBLEMS
25 * ================================
27 * This file provides an XML-RPC interface for PhpWiki.
28 * It checks for the existence of the xmlrpc-epi c library by Dan Libby
29 * (see http://uk2.php.net/manual/en/ref.xmlrpc.php), and falls back to
30 * the slower PHP counterpart XML-RPC library by Edd Dumbill.
31 * See http://xmlrpc.usefulinc.com/php.html for details.
33 * INTERFACE SPECIFICTION
34 * ======================
36 * The interface specification is that discussed at
37 * http://www.ecyrd.com/JSPWiki/Wiki.jsp?page=WikiRPCInterface
39 * See also http://www.usemod.com/cgi-bin/mb.pl?XmlRpc
40 * or http://www.devshed.com/c/a/PHP/Using-XMLRPC-with-PHP/
42 * Note: All XMLRPC methods are automatically prefixed with "wiki."
43 * eg. "wiki.getAllPages"
48 * Change to unit tests: XmlRpcTest v1, v2 and private
49 * Return list of external links in listLinks
50 * Support RSS2 cloud subscription: wiki.rssPleaseNotify, pingback.ping
52 * API v2 http://www.jspwiki.org/wiki/WikiRPCInterface2 :
54 * array listAttachments( utf8 page ) - Lists attachments on a given page.
55 The array consists of utf8 attachment names that can be fed to getAttachment (or putAttachment).
56 * base64 getAttachment( utf8 attachmentName ) - returns the content of an attachment.
57 * putAttachment( utf8 attachmentName, base64 content ) - (over)writes an attachment.
58 * array system.listMethods()
59 * string system.methodHelp (string methodName)
60 * array system.methodSignature (string methodName)
63 Test hwiki.jar xmlrpc interface (java visualization plugin)

836 * String pingback.ping(String sourceURI, String targetURI)
838 Spec: http://www.hixie.ch/specs/pingback/pingback
841 sourceURI of type string
842 The absolute URI of the post on the source page containing the
843 link to the target site.
844 targetURI of type string
845 The absolute URI of the target of the link, as given on the source page.
847 A string, as described below.
849 If an error condition occurs, then the appropriate fault code from
850 the following list should be used. Clients can quickly determine
851 the kind of error from bits 5-8. 0x001x fault codes are used for
852 problems with the source URI, 0x002x codes are for problems with
853 the target URI, and 0x003x codes are used when the URIs are fine
854 but the pingback cannot be acknowledged for some other reaon.
857 A generic fault code. Servers MAY use this error code instead
858 of any of the others if they do not have a way of determining
859 the correct fault code.
861 The source URI does not exist.
863 The source URI does not contain a link to the target URI, and
864 so cannot be used as a source.
866 The specified target URI does not exist. This MUST only be
867 used when the target definitely does not exist, rather than
868 when the target may exist but is not recognised. See the next
871 The specified target URI cannot be used as a target. It either
872 doesn't exist, or it is not a pingback-enabled resource. For
873 example, on a blog, typically only permalinks are
874 pingback-enabled, and trying to pingback the home page, or a
875 set of posts, will fail with this error.
877 The pingback has already been registered.
881 The server could not communicate with an upstream server, or
882 received an error from an upstream server, and therefore could
883 not complete the request. This is similar to HTTP's 402 Bad
884 Gateway error. This error SHOULD be used by pingback proxies
885 when propagating errors.
887 In addition, [FaultCodes] defines some standard fault codes that
888 servers MAY use to report higher level errors.
890 Servers MUST respond to this function call either with a single string
891 or with a fault code.
893 If the pingback request is successful, then the return value MUST be a
894 single string, containing as much information as the server deems
895 useful. This string is only expected to be used for debugging
898 If the result is unsuccessful, then the server MUST respond with an
899 RPC fault value. The fault code should be either one of the codes
900 listed above, or the generic fault code zero if the server cannot
901 determine the correct fault code.
903 Clients MAY ignore the return value, whether the request was
904 successful or not. It is RECOMMENDED that clients do not show the
905 result of successful requests to the user.
907 Upon receiving a request, servers MAY do what they like. However, the
908 following steps are RECOMMENDED:
910 1. The server MAY attempt to fetch the source URI to verify that
911 the source does indeed link to the target.
912 2. The server MAY check its own data to ensure that the target
913 exists and is a valid entry.
914 3. The server MAY check that the pingback has not already been registered.
915 4. The server MAY record the pingback.
916 5. The server MAY regenerate the site's pages (if the pages are static).
