Logos Delivery

    • use segment type instead of class

• [Deliverable] Add Segmentation to Reliable Channel API

  • next:
    • integrate nim-segmentation — replaces the skeleton in channels/segmentation/; pulls in nim-leopard, so cmake becomes a build-host requirement and the Android/iOS toolchain is a follow-up

Status

Status: Logos Delivery Integration

• [Deliverable] Integrate Messaging API in status-go
  • achieved:
    • feat(messaging): advertise WakuMessage version=0 on send — phase 2 of #7499, which is now closed
    • fix(waku): widen the filter full-node rate limit
  • next:
    • test(functional): migrate the functional-test fleet to a logos-delivery image, test(e2e): migrate the local e2e fleet to a logos-delivery image
    • chore(tests): use nightly Logos delivery node for functional tests

Maintenance

• achieved:
  • Stop epochmonitorfuture with rln stop — the epoch monitor future was never cleaned up
  • fix(build): misc build system fixes, fix: fix tests (e2e, macos)
  • fix(conf): drop duplicated dnsDiscovery name servers
  • chore(ffi): move the request registry out of ffi_types
• next:
  • fix(build): bump Nimble and chronos, simplify build — the new Nimble reads nimble.lock directly, so most of the resolution harness goes away
  • Refactor when nim-chronos shutdown is available
  • CI chores: unquote the forge-std branch, put foundry on PATH before using it
