From f0ebd36dda37e193c04742e0c24b947afda13bf6 Mon Sep 17 00:00:00 2001 From: Molecule AI Infra-SRE Date: Fri, 15 May 2026 15:55:25 +0000 Subject: [PATCH 01/19] fix(ci): increase Platform(Go) timeouts for cold runner tolerance MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Cold runners need ~45m for the full ./... suite with race detection + coverage (no Go module cache volume mount). Previous 10m step-level timeout was too short, causing CI to fail mid-test on cold runners while passing on warm (~12m). Changes: - go test -race -timeout: 10m → 60m - golangci-lint --timeout: 3m → 10m - job timeout-minutes: 15 → 75 Warm runner completion time (~12m) is well within the 60m ceiling. This fix is based on empirical data from PRs #1177 and #1107 cold-run failures and the warm-run success on PR #1199 (12m on warm runner).
