rpc: use synctest for TestClientCancelHTTP to fix CI flakiness by AskAlexSharov · Pull Request #20368 · erigontech/erigon

AskAlexSharov · 2026-04-07T03:54:19Z

Replace real TCP connections with in-memory net.Pipe-based listener for the HTTP cancel test, wrapped in synctest.Test for deterministic fake-time execution. The test now runs in ~0s instead of timing out on slow CI runners.

WebSocket cancel test keeps real TCP due to complex goroutine shutdown dependencies incompatible with synctest's bubble requirements.

Pull request overview

Updates RPC client cancellation testing to reduce CI flakiness by making the HTTP-path test deterministic and in-memory while keeping the WebSocket-path test on real TCP due to shutdown constraints.

Changes:

Refactors testClientCancel to split HTTP (synctest + in-memory listener) vs WS (real TCP) implementations.
Introduces memListener + memHTTPTestClient (net.Pipe-based) to avoid real networking in the HTTP cancel test.
Extracts the concurrent cancel-caller logic into runCancelCallers for reuse across transports.

💡 Add Copilot custom instructions for smarter, more guided reviews. Learn how to get started.

Replace real TCP connections with in-memory net.Pipe-based listener for the HTTP cancel test, wrapped in synctest.Test for deterministic fake-time execution. The test now runs in ~0s instead of timing out on slow CI runners. WebSocket cancel test keeps real TCP due to complex goroutine shutdown dependencies incompatible with synctest's bubble requirements.

Replace real TCP connections with in-memory net.Pipe-based listener for the HTTP cancel test, wrapped in synctest.Test for deterministic fake-time execution. The test now runs in ~0s instead of timing out on slow CI runners. WebSocket cancel test keeps real TCP due to complex goroutine shutdown dependencies incompatible with synctest's bubble requirements. err: ``` [WARN] [04-07|01:51:47.496] Cannot register RPC callback [invalidRets1] -
