From cd33aedf062bc83bcbbdff590a15a4fe90a9fb98 Mon Sep 17 00:00:00 2001 From: Molecule AI Core-DevOps Date: Mon, 11 May 2026 12:36:10 +0000 Subject: [PATCH] fix(harness-replays): use Gitea Compare API instead of git diff for detect-changes MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Replace the "Fetch base branch tip" step (git fetch that times out on Gitea runners per runbooks/gitea-operational-quirks.md §runner-network-isolation) and the git diff approach with a direct Gitea Compare API call. Before: 1. git fetch origin base-ref --depth=1 ← times out on runner 2. git diff BASE HEAD --name-only ← fails without fetch After: 1. Call Gitea Compare API (Gitea→Gitea, no runner network needed) 2. Parse JSON response for changed files 3. Apply path filter Also drops now-unnecessary fetch-depth:0 from the checkout step and removes continue-on-error: true from the decide step (the Compare API call is reliable from inside the Gitea Actions runner).
