Fixed smoldot westend integration test #170

x3c41a · 2026-01-12T09:43:48Z

Key Fixes

Smoldot Bootnode Issue

Problem: Smoldot light client couldn't connect to parachain nodes. Smoldot supports only WebSocket transport, but zombienet bootnodes used only TCP.
Fix: I added convertBootNodeToWebSocket() that converts TCP multiaddrs to WebSocket format using convention ws_port = tcp_port + 1. Zombienet nodes configured with --listen-addr /ip4/0.0.0.0/tcp/{port+1}/ws

Transaction Indexing

Problem: Parachain wasn't properly indexing transactions for the TransactionStorage pallet,
Fix: Enabled transaction-index feature on cumulus-pallet-parachain-system:
cumulus-pallet-parachain-system = { features = ["transaction-index"], workspace = true }

CI apt-get 403 Errors

Problem: Microsoft package repos on Github runners returned 403 Forbidden
Fix: Removed Microsoft repo lists before apt-get update

Other Changes

Added waitForChainReady to verify chain accessibility
Refactored smoldot script for parachain support (relay + para chain specs)

@x3c41a after your WS magic :) the authorize is finalized and store just waits to be included in the block: https://github.com/paritytech/polkadot-bulletin-chain/actions/runs/20950357905/job/60202260127?pr=170#step:12:151

maybe few things to try:

can we increase smoldot level to see more logs?
check PAPI repo issues/examples and/or fill the issue there with full logs and reference to this code

x3c41a · 2026-01-13T10:31:08Z

Reverted to the previous version,
Applied your suggestion (mine was buggy),
Increased smoldot log level

+        if (tcpMatch) {
+            const [, hostPart, portStr, peerId] = tcpMatch;
+            const tcpPort = parseInt(portStr, 10);
+            const wsPort = tcpPort + 1; // Convention: WS port = TCP port + 1


That's a convention that lives as a code comment here and in zombienet/bulletin-westend-local.toml implicitly.

Maybe it's worth extracting this convention somewhere? But where? @bkontur

@x3c41a thank you, nice one, please just remove bulletin-westend-spec.json file and we can merge

x3c41a · 2026-01-14T08:32:09Z

remove bulletin-westend-spec.json file

I also thought that it was redundant but it actually contains account balance overwrites which allow Alice (IIRC) to sign and send/spend the transaction. Otherwise Westend DAG test fails

x3c41a · 2026-01-14T08:52:46Z

May I merge? @bkontur

bkontur · 2026-01-14T09:27:15Z

May I merge? @bkontur

that file is generated by create_bulletin_westend_spec.sh and should be copied to the ./zombienet dir when running, please remove and let's see the CI

Ahhh, I see. I simplified that script too
