General

  • Sprint
    • Sprint 33 in progress. 
      • Consensus team
        • Completing foundation for bonding and unbonding in Rholang
        • Improve message protocol in Casper to improve perforamance
        • Providing peek to Casper
      • Node team
        • Investigation of challenges of processing a genesis block that includes RHOC balances
        • Support for investigation of testnet failure
      • Rholang team
        • Completion of work to bridge cost accounting with the wallet and proof of stake contract
        • Completion of work to resolve open bugs
        • Start on work to reduce Rholang garbage in the tuplespace
      • RSpace team
        • Investigation of the performance of RSpace
        • Completion of implementation of peek in Rholang
      • SRE team
        • Support for investigation of testnet failure
        • Completing infrastructure and tooling for hardening testing 
  • Release
  • Mercury requirements and acceptance criteria
  • Testnet status
    • Testnet-1 is down. RCHAIN-3593 - What's happening when pubnet validator nodes die without logging an error? Done  is a critical bug under investigation. We are currently running a test on the public testnet infrastructure to support the investigation. 
    • Please see RChain public testnet information to learn more about public testnet as well as a FAQ.
  • Community testing

Blockers to testnet-2

  • See complete view in  RCHAIN-3168 - Launch Testnet-2 Done
  • Planned steps to address delay in the launch of testnet-2
    • Release testnet-2 incrementally
    • Revisit how we understand the blockers and are dedicating development effort to them

Risks to code completion for Mercury

  • Addition of work in Rholang to address bloat in the tuplespace.  RCHAIN-3542 - Reduce Rholang garbage in the tuplespace To Do

Consensus

  • RCHAIN-3611 - Modify conflicts so that volatile events do not conflict Done  in review. This is part of the solution to resolving conflicting blocks observed with cost accounting.
  • Draft PR in for  RCHAIN-3582 - Refactor the feedback loop in Casper to improve message queuing and processing Done
  • PRs in review to complete the delivery of methods needed to build validator bonding/unbonding and rewards. 

    Key Summary T Created Updated Due Assignee Reporter P Status Resolution
    RCHAIN-3466 "closeBlock" part 3 for unbonding Story 24/May/19 3:41 PM 21/Aug/19 12:21 PM Ovidiu Deac Kelly Foster Medium Done Done
    RCHAIN-3465 "withdraw"method for unbonding Story 24/May/19 3:39 PM 21/Aug/19 12:16 PM Ovidiu Deac Kelly Foster Medium Done Done
    2 issues Refresh

Rholang

  • Resolution identified for two bugs that prevent the interpreter from stopping when an error occurs.  RCHAIN-3505 - Replayable error-model for Rholang To Do
  • First of two planned PRs in review for  RCHAIN-3220 - Rholang interpreter prints out unmatched sends To Do
  • Reviewing work needed to complete cost accounting.

RNode

  • Work in progress to resolve  RCHAIN-3561 - --private-key-path option should work for any instance where a private key is required Done  so that RNode operators can use a password protected key pair anytime a key is needed.
  • Node and SRE teams continuing the investigation of testnet issues observed late last week and through the weekend. The issues included nodes stopping without warning and not related to errors that would generate heap dumps at the time of death.
    • Completed work to provide more detailed metrics.
    • Running tests in testing networks
  • Investigation for  RCHAIN-3431 - Genesis creation runs out of memory after 2 days of runtime Done  revealed the RevGenerator contract to be the bottleneck. Next steps are to run benchmarks in Rholang to further investigate the issue. RCHAIN-3621 - Benchmark Rholang to further investigate inability to process genesis block that includes RHOC balances Done .

RSpace

  • PR review to deliver peek to Rholang.  RCHAIN-2107 - Modify rholang interpreter to accommodate peek behaviour. Done
  • Work in progress investigate performance of RSpace.  RCHAIN-3567 - Investigate the performance of new RSpace To Do
  • Draft PR in review for  RCHAIN-3509 - Remove source: Produce and source: Consume from Datum and WaitingContinuation. Preserve sequenceNumber. To Do  as part of the effort to optimize how source for produce and consume is stored.
