* 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!

* include "session is done" in the session transcriptJoey Hess2017-04-25
| | | | | | Including the process exit status. And cleaner Role.User shutdown sequence.
* fix connection closingJoey Hess2017-04-24
| | | | Now when the user quits, the developer also exits.

* 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.

* 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. This commit was sponsored by Boyd Stephen Smith Jr. on Patreon.
* 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.)

* 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.

* developer side checking of chain almost doneJoey Hess2017-04-17
| | | | | | | Seems to work well with networkDelay on both sides now. However, typing "top" causes the "to" to be accepted, but the "p" is rejected.
* Include Entered in the Activity chainJoey Hess2017-04-17
| | | | | | | | So when the developer makes 2 keypresses close together, they send the second Activity Entered with the first Activity Entered as its HashPointer. This allows the developer to prove the order they did things. This commit was sponsored by Peter Hogg on Patreon.

* copy terminal attrs to the ptyJoey Hess2017-04-13
| | | | | | | | | | | This fixes the control-d issue, and many more besides. See https://github.com/merijn/posix-pty/issues/11 Also though, it means that if the user has set some unusual stty value, it gets copied into the pty. We want this in debug-me, because it ought to replicate the environment it's run in as well as possible. This commit was sponsored by Thomas Hochstein on Patreon.
* use posix-pty, and forward SIGWINCHJoey Hess2017-04-13
| | | | | | | | | | | | | | | | I discovered the posix-pty library while looking for a way to forward SIGWINCH to the slave pty. It's taken care of a lot of nasty pty handling details, so let's use it! Unfortunately, this broke control-d exiting debug-me, which used to work great. I think that the problem is that readPty never returns B.empty, even on control-d. Or perhaps, posix-pty is doing something to the pty that prevents control-d getting through. I kept all the withoutMode code; at least withoutMode EnableEcho is still needed. This commit was sponsored by Jochen Bartl on Patreon.

Lots of terminal mode fun. Has a few warts still, but it works well enough to be comfortable, and even vim works ok. This commit was sponsored by John Peloquin on Patreon.
