* Handle going down with an exceptionmartin f. krafft2008-03-21
| | | | | | | | We previously used None as a sentinel to exit, but None is now a proper value, so now it's the job of an exception-like object (except it isn't an exception). Signed-off-by: martin f. krafft <madduck@madduck.net>
* put XMLStreamParser in public namespacemartin f. krafft2008-03-21
| | | | | | | Since we might throw sub-class exceptions, the class should be in the public namespace, meaning its name should not be prefixed with _. Signed-off-by: martin f. krafft <madduck@madduck.net>
* Allow individual hook registration to override IDmartin f. krafft2008-03-21
| | | | | | | | | The preprocessor hooks need to specify IDs different from the ID used to initialise the proxy. Thus, the hook function now takes an optional id keyword argument and uses the ID used during initialisation if none is provided. Signed-off-by: martin f. krafft <madduck@madduck.net>
* Refactor remote procedure calls in the proxymartin f. krafft2008-03-21
| | | | | | | | | | | Add an rpc() method to the proxy to allow users to call remote procedures, and route the proxy's own import registration via this function. Also, implement convenience functions for the RPC calls exported in the IkiWiki::XML::RPC namespace. Signed-off-by: martin f. krafft <madduck@madduck.net>
* Make proxy object available to hook functionsmartin f. krafft2008-03-21
| | | | | | | Hook functions now get the proxy object as first argument to be able to use RPC via the proxy. Signed-off-by: martin f. krafft <madduck@madduck.net>

* Allow external plugins to return no valuemartin f. krafft2008-03-21
| | | | | | | | | | | | | Instead of using the XML-RPC v2 extension <nil/>, which Perl's XML::RPC::Parser does not (yet) support (Joey's patch is pending), we agreed on a sentinel: {'null':''}, that is, a hash with a single key "null" pointing to the empty string. The Python proxy automatically converts None appropriately and raises an exception if a hook function should, by weird coincidence, attempt to return {'null':''}.

* Provide XML-RPC proxy abstraction for Python pluginsmartin f. krafft2008-03-15
The proxy module provides an abstraction to facilitate writing ikiwiki plugins in Python. Signed-off-by: martin f. krafft <madduck@madduck.net> (cherry picked from commit f347e83d82f26cdc59de17b754a78db58a933ea6)
