In Puppet 2.7 this is handled by the save method called on the node instance of Puppet::Node::Yaml which is a subclass of Puppet::Indirector::Yaml. The method that actually writes the node cache file to disk is implemented in the Puppet::Indirector::Yaml class here: https://github.com/puppetlabs/puppet/blob/master/lib/puppet/indirector/yaml.rb#L41-47 This save method is called on the master before the catalog is returned to the agent. I'm not sure why we're not writing this node cache in Puppet 3.x, but it may be a performance optimization because this is a synchronous write operation called in line while the agent is blocked waiting for a catalog to be returned. What are you trying to do with the node cache? Perhaps there's another approach in Puppet 3.x. For more detail, here's the point where the node cache is written to disk in Puppet 2.7. As you can see, this is happening in-line with the HTTP request so it's a bit of a performance concern for us. --> #0 Puppet::Indirector::Yaml.save(request#Puppet::Indirector::R...) at line /vagrant/src/puppet/lib/puppet/indirector/yaml.rb:34 #1 Puppet::Indirector::Indirection.expire(key#String) at line /vagrant/src/puppet/lib/puppet/indirector/indirection.rb:182 #2 Puppet::Node::Facts::NodeExpirer.save(instance#Puppet::Node::Facts, key#NilClass,...) at line /vagrant/src/puppet/lib/puppet/node/facts.rb:19 #3 Puppet::Resource::Catalog::Compiler.extract_facts_from_request(request#Puppet::Indirector::R...,...) at line /vagrant/src/puppet/lib/puppet/indirector/catalog/compiler.rb:26 #4 Puppet::Resource::Catalog::Compiler.find(request#Puppet::Indirector::R...) at line /vagrant/src/puppet/lib/puppet/indirector/catalog/compiler.rb:31 #5 Puppet::Indirector::Indirection.find at line /vagrant/src/puppet/lib/puppet/indirector/indirection.rb:196 #6 Puppet::Network::HTTP::Handler.do_find(indirection_name#String, key#String, params#Hash,...) at line /vagrant/src/puppet/lib/puppet/network/http/handler.rb:109 #7 Kernel.send(request#WEBrick::HTTPRequest, response#WEBrick::HTTPResponse, indirection#String,...) at line /vagrant/src/puppet/lib/puppet/network/http/handler.rb:68 #8 Puppet::Network::HTTP::Handler.to_s(request#WEBrick::HTTPRequest, response#WEBrick::HTTPResponse,...) at line /vagrant/src/puppet/lib/puppet/network/http/handler.rb:68 #9 Puppet::Network::HTTP::WEBrickREST.service(request#WEBrick::HTTPRequest, response#WEBrick::HTTPResponse,...) at line /vagrant/src/puppet/lib/puppet/network/http/webrick/rest.rb:24 #10 WEBrick::HTTPServer.service(req#WEBrick::HTTPRequest, res#WEBrick::HTTPResponse,...) at line /Users/jeff/.rvm/rubies/ruby-1.8.7-p334/lib/ruby/1.8/webrick/httpserver.rb:104 #11 WEBrick::HTTPServer.run(sock#OpenSSL::SSL::SSLSocket) at line /Users/jeff/.rvm/rubies/ruby-1.8.7-p334/lib/ruby/1.8/webrick/httpserver.rb:65 #12 Proc.listen(sock#OpenSSL::SSL::SSLSocket) at line /vagrant/src/puppet/lib/puppet/network/http/webrick.rb:45 #13 WEBrick::GenericServer.start_thread(sock#OpenSSL::SSL::SSLSocket) at line /Users/jeff/.rvm/rubies/ruby-1.8.7-p334/lib/ruby/1.8/webrick/server.rb:173 Cheers, -Jeff -- You received this message because you are subscribed to the Google Groups "Puppet Users" group.
