slack-get development diary #3
Hi,I was a bit lazy about blogging the slack-get development progression... Me bad, please accept my deepest apologies.
In the other hand, where do you think I spent all the time I didn't on blog ? Yes, you are right : playing SSX Blur on my Wii
More seriously, I made some nice improvements in sg_daemon :
- The file downloading code is now working and use a lot POE. If you checkout the code on Sourceforge's SVN and try out sg_daemon you will see that it is downloading all files to build the updates cache ! I'm quite happy to have this functionality working. Although it's not perfect and I'll make the slackget10::Network::Connection* drivers using the POE way of passing parameters. This will become very handy when I will update the drivers to a trully POE based architecture.
- The other big progress is about the network protocol. I think that I finally managed to define the needs of slack-get . The keys points are : flexibility and powerfullness. The XML based protocol I defined should meet those requirements. So I defined a base data structure that all network messages must respect, and after that I defined a way to serialize those data. So basically you just need the right serialization component to change the way sg_daemon and slack-get client talks. For the moment I will only develop the XML one but, in order to make easy the creation of other components, when a client connects to sg_daemon a quick handshake is made (sg_daemon send a message with the protocol version, client send a message with its protocol version and his supported serialisation method.
- Following the move slackget10::Network.pm was almost entirely rewrote to only format the network messages. A new class appeared : slackget10::Network::Message wich is an abstraction of a network message (unbelievable isn't it ?), an object of this type must now be give as parameter to all sg10::Network methods. Those changes are all due to the redefinition of the network protocol and to the rewriting of sg_daemon.
See ya next time !
