From 1bdf8b9b2da9faac6504c664ade9fb4e24642d2f Mon Sep 17 00:00:00 2001 From: Felix Lange Date: Thu, 15 Feb 2024 19:43:37 +0100 Subject: [PATCH] cmd/devp2p/internal/ethtest: some fixes for the eth test suite (#28996) Improving two things here: On hive, where we look at these tests, the Go code comment above the test is not visible. When there is a failure, it's not obvious what the test is actually expecting. I have converted the comments in to printed log messages to explain the test more. Second, I noticed that besu is failing some tests because it happens to request a header when we want it to send transactions. Trying the minimal fix here to serve the headers.
