@cirocosta any plans for tackling this one?

cirocosta commented 6 years ago

Hey @galvez , not really, even though it's an interesting one.

At the time I was going to perform A record queries as I was curious about how the docker internal DNS server would react.

Maybe something in the area of:

create N threads which form the worker pool
on each worker:
  - use epoll up to a limit of inflight non-blocking queries

Are you looking for something else in particular or does this scenario fits your needs?

@cirocosta Nope, just something to add my 2018 study todo list. I liked the project and have been looking for things to exercise my C. Aaaand am fairly familiar with DNS. Thanks for the pointers, you've been doing an awesome work.

That's cool! Thanks!

By the time I coursed networking I worked though this book: http://www.unpbook.com/

It's very "C" based and unix oriented so I highly recommend.

It doesn't cover some "new" stuff that is mentioned in the c10k problem (http://www.kegel.com/c10k.html) but it's pretty useful as a foundation.

Have a good one!
