* Leave the prevMessage out of Activity serialization to save BW.Joey Hess2017-04-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Do include it in the data that gets signed, so it can be recovered by trying each likely (recently seen) Activity as the prevMessage, and checking the signature. The UserState and DeveloperState already had the necessary state about recently seen hashes, so this does not impact data use. One tricky bit is that relayFromSocket needs to wait for the TMChan to be empty before calling restorePrevActivityHash. Otherwise, the hashes of items in the channel that have not been processed yet won't be tried. The TMChan is not really being used as a channel since only 1 item can be in it. It could be converted to a TMVar, but closeTMChan is used so I left it as a channel. Note that the server does not restore hashes of messages that pass through it; it's just a dumb relay. Sending a single key press now only needs 94 bytes of data to be sent, down from 169! --- Also switched to SHA512, since hashes are no longer being sent over the wire and so the larger size does not matter. SHA512 is slightly faster and more secure. This commit was sponsored by Ewen McNeill.

* include elapsedTime in ActivityJoey Hess2017-04-26
| | | | | | | | | | | | Time is relative, so the debug-me proof chain doesn't prove when things happened, but it's still useful to have some idea of how long things took to happen. This makes --replay work with logs gotten by --download. Log still includes loggedTimestamp. This is a bit redundant, and is unused now, but it's useful for log files to record when messages were received. This commit was sponsored by Riku Voipio.
* make developer accept messages from user that chain to other developer's ↵Joey Hess2017-04-26
| | | | | | | | | | | | | | messages This makes --download always work, which was the real motivation. It's probably a good ways to having multiple connected developers able to simulantaneously interact. I tested that breifly, and it seems to work ok! It may however, not handle it perfectly when both developers are trying to type at the same time. Still, nice that's basically working for free!

* it worksJoey Hess2017-04-22
| | | | | | | | | Multi-user client-server debug-me is working, almost perfectly. All that was missing was replaying the log when the developer connected. A number of race conditions had to be avoided to do that sanely. This commit was sponsored by Ignacio on Patreon.

* clean up connection closingJoey Hess2017-04-22
| | | | | | For some reason, runClient throws ConnectionClosed on apparently clean shutdown. This happens even though clientApp uses sendClose, and the server receives it and shuts down entirely cleanly.

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.
