Compiler / Interpreter status - what features will be ready for 3/29

@Kyle Butt, @Henry Till

• Open work items - what will happen next sprint.

• Joe is going on vacation

• Progress being made on the matching algorithm. Parallel matching is tricky. 

• Scala Protobuf will allow you to serialize and de-serialize to custom classes, so we were able to get a bitset and serialize it to bytes. 

  • we will do the same thing for maps and sets, allowing us to avoid the non-determinstic corners of protobuf (at the expense of lang interop)

• Storage tier is progressing fine.  In memory version is in flight, LMDB version is in flight as well. 

• Locking story is a WIP.  Competing writes is an issue we will need to look at.  

• Highest risk for 3/29 is the Evaluator - Joe's holiday was a surprise.  Fallback, halt matching work (it's done enough for 3/29) and ensure evaluator is solid

  • Enlist Kent's help as well.

Node Status - what features will be ready by 3/15

 @Chris Kirkwood-Watts / @Kelly Foster

• 3/15 is in excellent shape. Stretch goals - clearer by end of week

• Encryption and Handshake is moving along nicely.

• Talk about how much 'splash' we want for the 3/15 release, or do we defer in favor of 3/29

  • Blog post about release.

  • Demo?  Kelly and Medha to meet.  It's a small incremental improvement over the last release.

VM - Status.

@Timm Schäuble

• Plan for testing Transition function. 

  • We need to analyze the code coverage reports /tests and validate that the system is being properly tested.

• Compiler extraction plan - Keith to test this out starting next sprint.

• Primitives plan

Last meeting rolled over items

@Chris Kirkwood-Watts

• Compiler extraction plan - dive into details.

  • Will we run it in 32 bit mode?  It doesn't run particularly well in a modern Linux system.

    • Plan - Test that we can extract the environment literals, the compiler sets the VM environment.  That dependency needs to be broken.

      • Keith and Nash are working on this.

      • Need to include the 64 bit port of the compiler as part of the work items.

Depencies Discussion

• Lay out any dependencies that you may have on other teams work.

  • Node team will need to know how to integrate with Interpreter.  CLI and REPL are not done yet.  Kent is working on those pieces

    • Rholang team to deliver a REPL.  Node team will want to look at the main function and do the same thing. 

    • To integrate the Node and Interpreter, the file parser will look very similar to the current compiler. 

    • Read in a file → parse it → pass to Normalizer → pass to Interpreter.

Releases / Roadmap

Whats next.

Everyone

• Medha reviews Roadmap

• Medha needs to work with Mike to get the interface for the powerbox documented

  • Understand how the authority for the powerbox is bundled up and exposed.  We need more specificity so we can implement. 

  • Can Mike write the powerbox code to lay down an initial pattern and interfaces that the teams need to write code adhering to.

  • Get a pattern in place for the system contracts.
