hi,
please let me explain my idea of simple ruby-based backup system
on each node runs XML-RPC server; these nodes recieve commands from master server;
for example, node recieves:
Backup.run("rsync", "/etc", "backup.clnet.cz")
answers:
"code => "100", "description" => "command queued"
does backup (long-run process) and informs administrator (via email, or xml-rpc call to master server)
the problem is that i don't know how to implement this with xml-rpc ruby implementation; only way how to send answer to xml-rpc client is "return" in xml-rpc handler
so a little recap i want to receive command, answer to client and do something after it (and NOT receive command, do something and answer to client after it)
-------------------------------------------------------
require "xmlrpc/server"
server = XMLRPC::CGIServer.new
server.set_parser(XMLRPC::XMLParser::REXMLStreamParser.new)
class BackupHandler
def run(method, path, destination)
return "code" => "100", "description" => "command queued"
"backup stuff"
"xml-rpc call to master server"
end
end
server.add_handler("Backup", BackupHandler.new)
server.serve
