Logos Delivery

Messaging API — General Availability

• [Deliverable] Reliability and scale validation with DST

  • achieved:
    • chore(docker): rename compose folder and fix review follow-ups from #4057
    • docs: mark repository as archived, point to logos-delivery — the compose stack now lives in logos-delivery
  • next:
    • fix(e2e): stop the API/e2e suite segfaulting at process exit — the pool recycles FFI contexts without stopping their threads, so the interpreter finalizes the DSO underneath them; 20% of the api-e2e job failures

• [Deliverable] Create Rate Limit Manager

  • achieved:
    • make rate limit manager section clearer

RLN on Logos Blockchain

• [Deliverable] Implement pluggable RLN membership interface
  • next:
    • Add RLN api folder structure and consumer-facing interface — the seam from the RLN Module API spec, kept free of web3/keystore imports

Fleet Stability

• [Deliverable] Resolve known fleet stability issues
  • achieved:
    • fix: partition messages_lookup to stop the index bloat
    • Rework logging to be useful
  • next:
    • fix(archive): make a node that writes nothing visible — adds logos_delivery_archive_inserts_total{source}; a drifted database discarded a testnet’s traffic for 75+ hours with every signal green
    • fix(postgres): guard the partition maintenance against concurrent writers — two nodes per DC share one database, and a lost race killed the node inside the wrapper, so the container never exited and the restart policy never fired
    • fix(postgres): survive a database restart without leaking connections — closeDbConn failed before pqfinish, leaving connections open and turning a restart into quit(QuitFailure)
    • chore: Fix dead CLI config field for storeSync

Logos Chat

Chat — Beta

• [Deliverable] Stabilize and polish API

  • achieved:
    • expose ConversationClass : https://github.com/logos-messaging/libchat/pull/214
    • fix forking issue : https://github.com/logos-messaging/libchat/pull/217

• [Deliverable] Reliability testing with DST

  • achieved:
    • Update Chat-CLI with groups for testing: https://github.com/logos-messaging/libchat/pull/206
    • Update Chat-CLI with member management : https://github.com/logos-messaging/libchat/pull/208, https://github.com/logos-messaging/libchat/pull/209

Status

Status: Logos Delivery Integration

• [Deliverable] Integrate Messaging API in status-go
  • achieved:
    • feat: Messaging API (MessagingClient) — also migrates the bindings to the new nim-ffi C ABI and fixes two callback lifetime bugs found on the way
    • feat: let Nimble dependents build liblogosdelivery — ship library/, tools/ and migrations/ in the Nimble package
    • feat: DISABLE_RLN builds the library without zerokit — builds with no Rust toolchain and no vendored zerokit
    • fix(nix): emit and install the generated C header
    • status-go package layout — internal/, pkg/services, test/, root packages dissolved (#7723, #7724, #7725, #7726, #7732, #7733, #7740, #7741, #7742)
    • go-generate-fast: protoc --go_prefix, upstreamed
  • next:
    • feat: nimble package — pins the liblogosdelivery revision the bindings’ C ABI matches, so consumers inherit the pairing
    • feat(messaging): logos-delivery backend — build, bindings, adapter sketch
    • status-go protobuf v36 (#7738, #7739, status-app#22064, status-app#22067)
    • status-go networks service (#7747, #7748, #7749, #7750, #7751, status-app#22061)

Maintenance

• achieved:
  • nim-libp2p 2.2.1 stack merged onto the migration branch — libp2p NATService port mapping and live announced addresses (#4139, #4140, #4141, #4142, #4143)
  • fix(ci): daily build times out
  • fix(ffi): quarantine a context whose {.ffiDtor.} did not finish
  • boringssl: -fvisibility=hidden per compiled file
• next:
  • feat: migrate to nim-libp2p 2.2.1 — needs nim-libp2p-mix#54
  • chore: pin boringssl v0.0.11
  • nim-ffi: reverse FFI, pool-wide shutdown
  • logos-delivery-module: migrate to the nim-ffi 0.3 C ABI
