What you can expect this week

We will test deploy and propose across the network. Testing will be similar to this demo.

Steps:

  1. Connect to the bootstrap and find your peers.

  2. Deploy a contract to your local node.

  3. Propose a block and observe the fork choice rule.


Configure your network

See RNode supported network configuration for information on how to configure your network to connect to other nodes.

Installation instructions

Updated 7/10/18, 12:53 UTC

Please install RNode prior to the start of the testing session. 

NOTE - At this time RNode does not run successfully in Docker on MacOSX. This is because you must run Docker with the host networking option.  By default, Docker runs in network bridge mode.  To use the host networking option, you must include the 'network=host' option  in your Docker run command. This flag does not work on MacOSX.

docker pull rchain/rnode:testing

Other requirements

Download and save the bonds.txt file

  • Download the file from https://repo.pyr8.io/rnode-test-sessions/bonds.txt

  • Save the file in a /genesis directory

  • Note - If you previously downloaded and save the bonds file for a different testing session, you need to make a change. Previously the system looked for the bonds file in the /validators directory. Changes in the software now supports looking for the bonds file in the /genesis directory. Please make sure the bonds file is stored in the correct directory.

Select a validator key

Empty the var/lib/rnode directory

  • If you have previously run RNode, we advise you empty this directory.

Connect to the bootstrap node 

rnode://c61769b39d368cbcbc9499634e030386c79d5b02@52.119.8.108:40400

Run instructions

rnode run -b rnode://c61769b39d368cbcbc9499634e030386c79d5b02@52.119.8.108:40400

Note the port is different than what is described in the network configuration dock.

Share your experience

You best support the improvement and development of the RChain platform when you file a bug to report challenge you faced or unsuccessful outcomes. This will help us collect all relevant information to better understand your setup and experience.



Testing session summary

  • Connections
    • Five peer connections
    • People who couldn't connect
      • Hang on key generation (known issue)
        • core-826
        •  Mateusz
          • about slow cert generation on linux. i "fix" this problem on my machine by install http://www.issihosts.com/haveged/ its additional enthropy source. on redhat/centos: `sudo yum install haveged -y && sudo systemctl enable haveged && sudo systemctl start haveged`
on ubuntu change yum to apt this is not safe. because random number generation will be far from ideal but ok for testing I think
          • Was able to connect after employing the fix described above
      • Node crash on startup java.lang.NullPointerException (core-821)

      • hang
        • core-822
        • both the show-blocks command and the propose commands both cause my terminal to hang
        • when i use the deploy, propose and show-blocks commands I get errors starting with “WARNING: An illegal reflective access operation has occurred”
    • Unable to see proposed blocks
      • core-825 
      • everyone has a different genesis block hash
      • Medha's genesis block
        • blocks { blockHash: "b87b9038f42e4811de2d143efc583a36f98b6324a8c2f672ce2784ce5e05900a" blockSize: "11717" blockNumber: 0 version: 0 deployCount: 0 tupleSpaceHash: "" tupleSpaceDump: "Tuplespace hash not found!" timestamp: 0 faultTolerance: -1.0 mainParentHash: ""

      • Fix is clearing the data directory

      • Node assumes you're starting with a clear tuplespace. If you didn't shut down with an empty tuplespace, then node thinks the tuplespace is empty when it's not.

      • There may be another issues at play
      • It may also be a problem that the bootstrap was not cleared
      • Medha 
        • After 2 deploys and 2 proposes
        • "Tuplespace hash not found"
