Logbook

This page records a log of the team’s work, thinking, discussions, pains, joys, events, and experiences that happen on a daily basis. It’s supposed to be a kind of Stream of consciousness that can later be searched, analyzed, reviewed in more formal retrospectives.

Rules:

• Log days in reverse chronological order, recent first

• When the stream is getting too big, such that github refuses to render do the following:

  • extract biggest logical section (half-year or quarter) out of this into a correspondingly named Logbook-Year-Hn.md or Logbook-Year-Qn.md page
  • update links on top of this page to make it easier to navigate try to fix all links in the wiki at least
  • notify the team

• Move (and link) recurring sections to relevant dedicated pages.

2024-09-13

• Today, we worked on these issues:
  • Release 2437 distribution #1901: we have decided to wait until almost all the signers run a version >0.2.170 before we can activate the certification of the Cardano stake distribution. We have also noticed that the signature of the Cardano transactions stopped working on pre-release-preview and we suspect that a state corruption may have happened between stable and unstable versions of the Cardano transactions. We will keep investigating and probably create a fix with a new pre-release distribution
  • Aggregator buffers signatures for unknown open message #1900: the PR Aggregator single signatures buffer #1934 has been created and is pending review

  • We have also checked if some of our test SPOs needed to have their KES keys rotated: this was not needed

2024-09-12

• Today, we have worked on these topics:
  • Release 2437 distribution #1901: we have released the 2437.0-pre which has been deployed to the pre-release-network. We have noticed some problem with the signers running the previous version of the signer when we have activated the certification of the Cardano stake distribution: the signers were crashing and restarted to register to the aggregator. We have deactivated the certification until we notice enough signers run the latest version in order to minimize the crashes on the signer. We have also identified where the problem lies in the code, and it is due to some todo!() which was shipped with previous versions. This is not something that will happen with the Cardano transactions once activated on the release-mainnet: outdated signers will just log an error when they see a pending certificate for a signed entity type they don't know yet. We will keep monitoring the deployment until we are ready to create the release distribution. It is expected to be the case early next week
  • Aggregator buffers signatures for unknown open message #1900: we have kept working on the issue and the developments have been pushed to the ensemble/1900/aggregator_signatures_buffer branch. A PR will be created shortly
