High level summary​

On the performance side, the team ran benchmarks for the the P2P feature and the 1.35.4 release. We finished a prototype for performance data publishing. We almost finished the local deployment backend for the workbench using the new SRE deployment infra. We worked on fixing and improving our data analysis pipeline.

On the tracing side, the team worked on isolating a critical issue causing message loss in the remote tracing backend. The issue was resolved and we now have proper end-to-end coverage for the scenario.

Executive summary​

  • The new tracing system public release is getting closer, as we're resolving remaining rough edges that are discovered in full-scale deployments. The local benchmarks we ran were already showing improvement relative to legacy tracing, so we expect similar results at full scale.
  • The first (local deployment) iteration of benchmarking adopting the new SRE deployment infra is nearly done. We thank Michael Fellinger and Robin Stumm for their assistance. Two further phases remain: CI integration and cloud deployment.
  • The benchmarking data publishing prototype is ready. This serves as a springboard for both opening our performance assessment workflow (to support the wider Cardano developer community), and for data provision to the business community. Our next steps are to secure a permanent deployment for this mechanism and to integrate it into the benchmarking infrastructure. This requires collaboration with SRE.

High level summary​

The SRE team is heavily working on the Equinix Metal migration, replacing Hydra with Cicero, and a new version of Spongix.

Lower level summary​

OpenZiti​

  • Work is ongoing on our OpenZiti integration into Bitte in [bitte-zt].
  • CI-World deployment of Darwin CI Ziti service in [ci-world-commit-d40f4d].
  • Multiple issues filed, and a lot of discussion with the OpenZiti developers, we're making pretty rapid progress thanks to them.
  • Work on getting Equinix baremetal machines integrated into AWS World Bitte clusters utilizing a Ziti ZTNA network overlay to bridge the networking of the two environments and get IAM extension to Equinix machine for Nomad client onboarding.
  • A Nix Flake for most of our OpenZiti dependencies including the Console, Controller, Edge Tunnel, and Router is now at [openziti-bins].
  • The Flake also includes a WiP NixOS modules for these components.
  • Tested Ziti Desktop Edge official app for Darwin x86_64 w/ GUI -- works with no issues seen so far
  • Moved the console to traefik routing service (zac.$DOMAIN) and controller/edge router stay at zt.$DOMAIN, but have registered consul services

Cicero & Tullia Integrations​

Cicero & Tullia Features​

  • Improvements to Tullia task aggregation to make [cardano-addresses] build correctly.
  • Better tullia CUE lib default for tags [tullia-commit-4df3c5d].
  • Put cache.nixos.org back in cache.iog.io's upstreams. This is now considered a public cache again, and without it some Cicero evaluations had to build huge packages.
  • Started working on a flake-parts module for Tullia.
  • Started working on cutting down Tullia task build time by putting facts in JSON files.
  • Fixed running into kernel arg limit by reading tullia's DAG from a file
  • Merged [tullia-pull-9] that fixes several issues related to error reporting. and escaping.
  • Added Mac builders in Cicero on CI-World.
  • Started work on Tullia invocation caching.

Spongix​

  • A lot of progress on an SQlite backed version of Spongix, it already supports the full HTTP binary cache protocol but still lacks comprehensive testing and some tuning, as well as recursive lookups.
  • First steps in the implementation of the nix-daemon ssh-ng protocol so Spongix can be used via SSH and we can get rid of basic auth.

Bugs​

  • Discovered Cicero bug where Nomad reschedules cause the Github commit status to get stuck in pending
  • Discovered Cicero race condition bug around concurrent transactions for codependent actions.
  • Fixed tullia task order bug in [cardano-addresses]
  • Diagnose Cicero action not triggered in [abcirdc]
  • Fixed meta/description of the Tullia package in [tullia-pull-7]
  • Add Vault token loop alerts in [bitte-cells-pull-40]
  • Ongoing investigation on recurring Patroni and nomad-follower issues related to token rotation.

High level overview​

The crypto team is primarily focusing in enabling SECP primitives, and preparing the KES agent. We are close to meeting the acceptance criteria in cardano-base, which lacks some editorial comments on the style of dQuandrant's PR, the inclusion of one additional test, and we are good to mark it as done. For the KES agent, we are still iterating over the best design of the solution, but also progressing on the implementation.

Low level overview​

SECP built-ins​

  • (missed last two weeks update) Audit was succesfully completed by bCryptic, and some minor changes where addressed in PR 313
  • CIP-0049 was addressed in the editors meeting, and PR 250 was merged
  • The unit-tests PR 320 is opened. Some editorial concerns still need to be addressed, and an additional (negative) test has been requested for addition.

KES agent​

  • We were working in investigating how to send OpCerts to KES agents, but turns out to be not necessary. OpCerts can be stored on-disk, so the agent does not need to be aware of them.
  • We are redesigning the architecture. Instead of connecting the control server to the agent, and then the latter to the node, we are directly connecting the control server to the node, and the latter to the agent(s).

High level summary​

This week, the hydra team reviewed and addressed several open comments on the new HeadV1 specification, completing a list the of identified gaps between specification and implementation while doing so. In the wake of the recent demonstration of SundaeSwap running their DEX in a Hydra Head, they met with them to capture feature ideas & incorporate their feedback on the roadmap, as well as potential research avenues.

What did the team achieve this week​

What are the goals of next week​

  • Complete the last two items required for a version 0.8.0.
  • Cut the next release, version 0.8.0
  • Get backup/recovery #187 done with proper event sourcing (ADR18)
  • Have the CI build macos artifacts

2022-10-19 - 2022-11-01

High level summary​

This sprint saw the addition of the long awaited tx-mempool command that allows user to query the local node's mempool for the following information:

  • Ask the node about the current mempool's capacity and sizes
  • Request the next transaction from the mempool's current list
  • Query if a particular transaction exists in the mempool

Outside of this feature the team has been focused on responding to user requests (e.g exposing functions, types and implementing instances they need) and refactoring cardano-cli/cardano-api. The metric tx_submit_fail_count has been added to the submit api so users can track how many transactions have failed. Other improvements have been made:

  • Documentation improvments
  • Release 1.35.4 was merged & released
  • Exported various types from cardano-api that were requested by community members
