Title: Lifecycle of a Message Post by: cloudboy on August 20, 2014, 04:31:41 AM I understand that messages are handled by ThreadMessageHandler in net.cpp, and are received/sent/processed in main.cpp.
My questions are:

No. Quote Is pnode->PushMessage() enough to broadcast a message? From what I understand, it adds the message to the queue of outgoing messages, which are then gathered by SendMessages() and sent. PushMessage sends a message to a peer. Only certain message types are then broadcast to the rest of the network. Quote Is it possible to assign an expiration date to an individual message? So all nodes know to stop propagating it at that time? No, but that's not necessary. Nodes don't propagate duplicate information, so block/tx/addr broadcasts reach every network node in a matter of minutes and then stop propagating. Quote How can you reject an incoming message and make sure it doesn't get relayed or processed? Just ignore it when you receive it. ProcessMessage would probably be a good place to put additional logic of this sort. |
