From 04700e97d372bec715e9f911507db0a650a60d14 Mon Sep 17 00:00:00 2001 From: Patrick Ohly Date: Tue, 3 May 2022 13:18:23 +0200 Subject: [PATCH] hack: prepare for strict golangci-lint in pull-verify-kubernetes The long-term goal is that when "make verify" is invoked in pull job, it will also run golangci-lint with the strict configuration and write an $ARTIFACTS/golangci-lint-githubactions.log file with GitHub actions annotations. How to get those published for the GitHub PR is open. When "make verify" is invoked manually or in any other job, the stricter check will be skipped. That works because "PR_NUMBER" is only set for pre-merge jobs (https://github.com/kubernetes/test-infra/blob/master/prow/jobs.md#job-environment-variables). Because strict linting is still new and might not be useful without a better UI (= GitHub annotations), this PR does not fully enable the integration into "make verify". Instead, the new verify-golangci-lint-pr.sh is excluded from it and needs to be run in a separate job. --- hack/make-rules/verify.sh | 1 + hack/verify-golangci-lint-pr.sh | 37 +++++++++++++++++++++++++++++++++ hack/verify-golangci-lint.sh | 33 ++++++++++++++++++++++------- 3 files changed, 63 insertions(+), 8 deletions(-) create mode 100755 hack/verify-golangci-lint-pr.sh diff --git a/hack/make-rules/verify.sh b/hack/make-rules/verify.sh index 41ab4adcb7f..1d5556ac8a2 100755 --- a/hack/make-rules/verify.sh +++ b/hack/make-rules/verify.sh @@ -33,6 +33,7 @@ source "${KUBE_ROOT}/third_party/forked/shell2junit/sh2ju.sh" EXCLUDED_PATTERNS=( "verify-all.sh" # this script calls the make rule and would cause a loop "verify-*-dockerized.sh" # Don't run any scripts that intended to be run dockerized + "verify-golangci-lint-pr.sh" # Don't run this as part of the block pull-kubernetes-verify yet.
