Just celebrated my birthday this last weekend, so apologies for forgetting last week’s update!
During testing at the beginning of last week, I realized that the mutex structure I had originally created to handle shared state was untenable for a system this size and complexity. I was getting repeated hangs where one thread would lock A and wait for B while another would lock B and wait for A. I decided I was going to have to use channels, handlers and internal message passing for shared state instead of trying to have mutexes for everything. As such, I began channelizing the main parts of the program last week. I was able to channelize the best header chain handler, and the peer handler and test them. I have begun work on have a handler deal with chain fragments, but this has proven to be more difficult more due to the complexity of dealing with chain fragments (and partial chain fragments) then anything to do with channels. Still, I am making progress and plan to have nearly everything channelized by the end of the week.
Let the channelization commence!
