Repository Work​

Cardano-faucet​

Cardano-parts​

  • Sets cardano-node to 10.1.1, mithril to v2442.0 and updates iohk-nix-ng for the recent sanchonet respin. Updates for cardano-cli breaking changes were incorporated into nix jobs, justfile recipes, bash and python scripts, process-compose processes. New template just recipes and psql prepared statements were added for ease of governance action pool voting and follow up vote analysis. Some nixosModule options were refactored for consistency across the module set. More detail is available in the release notes: cardano-parts-release-v2024-11-06

Cardano-playground​

  • Sets cardano-node to 10.1.1, mithril to v2442.0. Sanchonet was respun on 2024-10-21 and private and shelley-qa chains were retired. Breaking change fixes for cardano-cli were applied and new just recipes added. More detail is available in the PR description: cardano-playground-pull-35

Cardano-mainnet​

  • Sets cardano-node to 10.1.1, mithril to v2442.0. Kes was rotated for block producers. Breaking change fixes for cardano-cli were applied and new just recipes added. More detail is available in the PR description: cardano-mainnet-pull-25

High level summary​

The SRE team continues work on Cardano environment improvements and general maintenance.

Some notable recent changes, updates or improvements include:

  • All environments have been upgraded to cardano-node 9.2.1.

  • Cardano-faucet 9.2 is available and deployed which is compatible with node 9.2.x and has fixed ipv6 functionality.

  • All deployed machines now default to nix 2.24-maint after an upstream bug causing a hash miscalculation in submodules has been fixed. Nix 2.21 forward required some rework of the colmena deployment recipes as dirty git trees now force an impure colmena deployment.

  • To ease the process of upgrading cardano-parts, releases will now be made instead of only PR merges with migration notes.

Repository Work​

Cardano-faucet​

  • Binds ipv6 interface in addition to ipv4, parses and logs all ips to a unified ipv6 format and applies hlint and fmt updates. cardano-faucet-pull-14

  • Makes required changes for cardano-api 9.2.0.0 and 9.3.0.0, removes void type sig constraints, bumps haskellNix, CHaP, cardano-api -> 9.3.0.0 for node 9.2.x compatibility. Disables mingw32 builds until alex in current haskellNix pin is updated. cardano-faucet-pull-15

Cardano-parts​

Begins cardano-parts date-based releases for an improved upgrade process. Adds misc fixes and improvements. More detail is available in the release notes: cardano-parts-release-v2024-10-07

Cardano-playground​

  • Deploys cardano-node to 9.2.1, cardano-faucet to 9.2. Bumps nix to 2.24-maint and adds ipv6 and nix versioning fixes and other improvements. Adds a wip node pparams api server. More detail is available in the PR description: cardano-playground-pull-33

Cardano-mainnet​

  • Deploys cardano-node to 9.2.1, bumps nix to 2.24-maint and adds ipv6 and nix versioning fixes and other improvements. Converts bootstraps to a new cached-index-patch branch and upgrades CF canary sql queries. More detail is available in the PR description: cardano-mainnet-pull-23
