Weekly Update (@notunrandom)

What did you work on this week?

• https://github.com/CardanoSolutions/kupo/pull/204
  • Investigated the 6 failing/flaky end-to-end tests:
    • "restart(s)"
    • "read-only permissions"
    • "point when syncing"
    • "auto-magically"
    • "can connect"
    • "point when at the tip"
  • There is a new race condition that occurs, owing to the way the endToEnd tests are run (with skippableContext)
  • May be related to some of the hackage upgrades
  • Decided to re-write those flaky tests (see next item)
• https://github.com/CardanoSolutions/kupo/tree/flaky
  • create separate test suite
  • extract "read-only permissions" into new format

What outcome/key result did it support?

• Maintain Kupo among the top three most-used Cardano chain indexers as measured by state of the Cardano developer surveys. Specifically:
  • Ensure software compatibility with upcoming intra-era hard forks & eras

What's immediately next?

• Extract the remaining flaky tests and push to master
• Rebase PR#204, finalise and merge.
