* initial http serverJoey Hess2017-04-21
| | | | | | | | | | | | Incomplete, but the client is able to connect and send messages which get logged. Split up debug-me.hs into Role/* Switched from cereal to binary, since websockets operate on lazy ByteStrings, and using cereal would involve a copy on every receive.

* use cereal for efficient serialization for wire formatJoey Hess2017-04-21
| | | | | | | | | | | I tried both binary and cereal. For a ActivityMessage that takes 341 bytes in JSON and has a dataSize of 129, both used 165 bytes. Went with cereal since lazy bytestrings are not needed, and I might want to use https://hackage.haskell.org/package/safecopy later. (Perhaps I should be using protocol buffers or something to make it easier for non-haskell implementations? But that would complicate things a lot.)
* reorganized message typesJoey Hess2017-04-19
| | | | | | | | | Make Control messages be out-of-band async messages, without a pointer to a previous message. And then followed the type change through the code for hours.. This commit was sponsored by Nick Daly on Patreon.
* initial CryptoJoey Hess2017-04-18
| | | | | Will use Ed25519 because it's from DJB and well regarded and in common use now.
* memory DOS preventionJoey Hess2017-04-18
| | | | | | | | | | | | Prevent DOS of user side by limiting the size of the BackLog that is maintained. This should not cause problems in even high latency environments, and should prevent memory use > 16 mb. The developer side does not keep much data, other than a list of the Hashes of things it has recently sent, so is not susceptable to memory DOS.
