High level summary​

We started working on a new way to switch between root & ledger peers (see below). We continued to work on eclipse-evasion. We merged changes to Handshake contributed by Galois Inc. We made improvements to our tests (fixed a flaky test, added cddl specs for NodeToNodeVersionData and NodeToClientVersionData). We improved our CI and automated the process of releasing new package version to CHaP.

Detailed summary​

We continued to work on testing eclipse-evasion.

We came up with an idea to limit how full node wallets relay on root peers (currently operated by IOG, in future also CF and Emurgo). We designed a switch to use ledger peers if the node tip is close enough to the current time. For more details see #4530.

We merged changes to the handshake mini-protocol which allow one to query server's node-to-node / node-to-client parameters. We are grateful to Galois Inc. for implementing it, #4256 and #4538. We published new version of packages to CHaP chap-#253.

We added DiffusionError wrapper. Thanks to it, ouroboros-consensus will not duplicate diffusion errors messages in the log, #4537.

We fixed an issue which caused one of our tests to be flaky, #4515.

We added cddl tests for NodeToNodeVersionData and NodeToClientVersionData: #4540, #4544 (in review).

We wrote scripts which will help us release packages as well as verify that we released all the package necessary to build the newest set of packages, #4542.

We renamed the consensus startup tracer and make sure it doesn't log ExitSuccess exceptions, consensus-#71.

We reviewed PR which adds RawBearer API, #4395.

We made series of improvements to our CI:

  • #4539: we don't need to install cryptographic libraries in CI;
  • #4545: Javier Sagredo (consensus) cleaned up CI after consensus moved to a new repo;
  • #4546: we switched to use GitHub merge queues;
  • #4549: we made it possible to trigger building haddocks manually;
  • #4553: we fixed and enhanced caching of building dependencies.
