Hi:
how about use makeClassy for Config type?

in Config.hs

          module Juno.Types.Config
          ( Config(..)
          , HasConfig(..)   -- we don't have to list all the fields here
          , KeySet(..), ksClient, ksCluster
          ) where

             -- makeLense ''Config
             makeClassy ''Config

in Simple.hs

         instance HasConfig (RaftEnv m) where
             config = cfg

then we can access config field like this:

    nid <- view (cfg.nodeId)   -- it's ok
    nid <- view nodeId         -- it's ok too

After update to julia-client v.0.5.12 and ink v. 0.6.3 plots do not fit the plot pane anymore:

Everything was fine right before the update.

language-julia v. 0.10.0
Running Juno under Windows.

I'm facing a wierd exception about SHA2 installation, when calling "cabal install". the description ends with ExitFailure1 !!

Attached is the log file
sha2.txt

I'm using Ubuntu 16.04 LTS on Virtual Box.

the build works, but when trying to run ./junoclient.sh it throws

rlwrap: error: Cannot execute junoclient: No such file or directory.

Any troubleshooting would be helpful, and will contribute to adding details to project!
Thanks :)

Is this project still active?

In the read me it says:
"There were fundamental issues with the protocol and implementation that removed further stability, performance, and scalability gains."

I'm curious if those issues were every publicly presented?

Looks like there is an issue running the demo if installing on Mac and using brew to install tmux. Must manually install an older version of tmux <= 1.8 appears to work.

hello everyone :
i have spent a lot of time to read juno code and run the test in my computer
i am trying to implement persistence feature myself, and this is my idea and plan:

       1.   change Seq LogEntry  to   Seq (LogIndex, LogEntry),  all unapplyed command stay in memory, and all applied command save to database.

       2.  declare PLogEntry , means persisntent LogEntry:

-- 只保存已经确认并已apply的LogEntry
share [mkPersist sqlSettings, mkMigrate "migrateBlockchain"] [persistLowerCase|
PLogEntry
    index Int
    term Int
    clientId ByteString
    requestId ByteString
    commandEntry ByteString
    commandSig   ByteString
    quorum_votes  ByteString
    sig           ByteString
    hash    ByteString
    commandResult ByteString
    deriving Show
|]

  3.  when server start , i need to load latest logentry to memory(LastAppliedIndex, LastCommitIndex...)

  4.  when a command is confirmed and applied, i need to write it to the database

  of course it need modify a lot of code ,  

  is this idea works? or any better idea?

 by the way , can i join the dev team and do some develop work? and how?

It really cool that use guy have achieved this and are working on it. I hope you don't mind If I use this heavily as a learning tool for architecting solutions for my own project http://prometheus.network and https://github.com/Prometheus-SCN

It seems that Juno and acid-state (Hackage) is a match made in heaven - eventual consistency with ACID guarantees on each of the nodes, allowing for any* haskell datatype to be easily turned into a distributed shared variable. I was planning to implement this myself, but since large changes are planned, I thought I'd make the suggestion so it can be implemented internally instead of needing to be rewritten once the changes are made.
