From 8d28d7396db66da84be620c6447d7785b7751121 Mon Sep 17 00:00:00 2001 From: Ubuntu Date: Thu, 14 May 2026 18:25:41 +0000 Subject: [PATCH 01/11] feat: add --no-blockchain experiment for routing commits/identity updates to nodes Adds feature flags (XMTPD_PAYER_NO_BLOCKCHAIN, XMTPD_API_NO_BLOCKCHAIN) that bypass blockchain for commit and identity update messages, routing them to dedicated nodes instead. This enables testing XMTPD without Arbitrum L2 dependency as proposed in the "xmtpd without chain" experiment. Changes: - Add NoBlockchain, CommitNodeID, IdentityNodeID to PayerOptions and APIOptions - Modify payer groupEnvelopes() to route blockchain-bound messages to nodes - Make 3 node-side rejection points conditional on NoBlockchain flag - Wire config through gateway builder with WithNoBlockchain option - Add triple profile to docker-compose with 3rd postgres (port 8767) - Add dev/run-3 and dev/run-no-chain convenience scripts - Add 3rd Anvil account to local.env and node registration in dev/docker/up Co-Authored-By: Claude Opus 4.6 --- dev/docker/docker-compose.yml | 12 ++++++++++-- dev/docker/up | 20 +++++++++++++++++--- dev/local.env | 6 ++++++ dev/run-3 | 17 +++++++++++++++++ dev/run-no-chain | 23 +++++++++++++++++++++++ pkg/api/message/service.go | 6 +++--- pkg/api/payer/config.go | 13 +++++++++++++ pkg/api/payer/service.go | 15 ++++++++++++++- pkg/config/options.go | 8 ++++++++ pkg/gateway/builder.go | 19 +++++++++++++++++-- 10 files changed, 128 insertions(+), 11 deletions(-) create mode 100755 dev/run-3 create mode 100755 dev/run-no-chain diff --git a/dev/docker/docker-compose.yml b/dev/docker/docker-compose.yml index 88769082c..7aaff4068 100644 --- a/dev/docker/docker-compose.yml +++ b/dev/docker/docker-compose.yml @@ -3,7 +3,7 @@ x-postgres-image: &x-postgres-image postgres:16 services: db: image: *x-postgres-image - profiles: ["single", "dual"] + profiles: ["single", "dual", "triple"] environment: POSTGRES_PASSWORD: xmtp ports: @@ -11,12 +11,20 @@ services: db2: image: *x-postgres-image - profiles: ["dual"] + profiles: ["dual", "triple"] environment: POSTGRES_PASSWORD: xmtp ports: - 8766:5432 + db3: + image: *x-postgres-image + profiles: ["triple"] + environment: + POSTGRES_PASSWORD: xmtp + ports: + - 8767:5432 + chain: platform: linux/amd64 image: ghcr.io/xmtp/contracts:v2026.02.10-1 diff --git a/dev/docker/up b/dev/docker/up index cbf5d37e4..45beb24f7 100755 --- a/dev/docker/up +++ b/dev/docker/up @@ -4,7 +4,7 @@ set -eo pipefail if [ -z "$1" ]; then profile="single" echo "No profile provided, defaulting to single" -elif [ "$1" = "single" ] || [ "$1" = "dual" ]; then +elif [ "$1" = "single" ] || [ "$1" = "dual" ] || [ "$1" = "triple" ]; then profile="$1" else echo "Invalid profile '$1', defaulting to single" @@ -51,8 +51,8 @@ run_cli \ --add \ --node-id=100 -# Register and enable node 2 (dual only) -if [ "${profile}" = "dual" ]; then +# Register and enable node 2 (dual or triple) +if [ "${profile}" = "dual" ] || [ "${profile}" = "triple" ]; then run_cli \ nodes register \ --owner-address="${ANVIL_ACC_2_ADDRESS}" \ @@ -65,4 +65,18 @@ if [ "${profile}" = "dual" ]; then --node-id=200 fi +# Register and enable node 3 (triple only) +if [ "${profile}" = "triple" ]; then + run_cli \ + nodes register \ + --owner-address="${ANVIL_ACC_3_ADDRESS}" \ + --signing-key-pub="${ANVIL_ACC_3_PUBLIC_KEY}" \ + --http-address="${NODE_3_HTTP_ADDRESS}" + + run_cli \ + nodes canonical-network \ + --add \ + --node-id=300 +fi + echo diff --git a/dev/local.env b/dev/local.env index b84dacb36..5a2a24cc0 100755 --- a/dev/local.env +++ b/dev/local.env @@ -34,6 +34,12 @@ export ANVIL_ACC_2_PUBLIC_KEY="0x039d9031e97dd78ff8c15aa86939de9b1e791066a0224e3 export ANVIL_ACC_2_ADDRESS="0x3C44CdDdB6a900fa2b585dd299e03d12FA4293BC" export NODE_2_HTTP_ADDRESS="http://localhost:5051" +# Account 3.
