  • Fixed timestamp bug
  • Updated traffic injection to continuous operation
  • Created IPFS mesh slices of arbitrary time length
• analysis:nomos:simulation-analysis
  • Finally zero'd in on the tree/branch bug. The pre and post-analysis are fine, the bug is in the Carnot sim.

• dr-support:vac:carnot-2-3rds-python-impl
  • investigate Carnot sim code
• eng-10ktool:vac:bandwidth-test
  • Finish exporting metrics (delayed)
  • Make sure new CIDR configuration supports 10k PODs
• wakurtosis:vac:rlog
  • finish simulations
• software-testing:waku:test-automation-js-waku
  • New tests:
    • Relay[WIP]
  • Improvements:
    • Speed up execution from 12m to 3.5m for 250 tests through parallelization(Significant refactoring needed to achieve this)
    • Follow up fix to only allow paralellization in CI env
  • Fixes:
    • Updated tests after gowaku store fixes
    • Updated tests after remote peer rejected error
• software-testing:waku:test-automation-nwaku
  • Relay and message id tests
    • PR
  • Merge filter subscribe PRs; Pending unsubscribe, missing one review.
  • Heavily investigate issues shown on tests
    • Max 1MB message size, no graceful handle.
    • After stopping and restarting a relay node, can't reconnect it with connectRelay.
    • Can't stop a relay node and send a message: Inconsistent with filter push behaviour.
    • Publishing multiple messages in a row triggers the same SEGFAULT as when refreshing a subscription.
• software-testing:waku:test-automation-go-waku
  • Wrote five tests - were added to the branch https://github.com/waku-org/go-waku/tree/chore(filterV2)-test-updates
  • Reported issue "Messages won't get through with multiple pubsub topics" https://github.com/waku-org/go-waku/issues/804
  • Tracking coverage as notes so far -> will change to tabular form. Notion has API, we could possibly update docs during test execution? https://www.notion.so/Filter-Test-Coverage-42fc15b503ec4621980a7757d85089db?pvs=4
