From d229bb760c49b65e19ec28342236961ad961d7fe Mon Sep 17 00:00:00 2001 From: Ridha Chahed Date: Mon, 13 Jul 2026 17:01:07 +0200 Subject: [PATCH 2/4] Bug#39724798 Streamline GitHub contribution automation Problem: ======== The GitHub contribution path lacked consistent intake templates, shared local CI entry points, and automated build, test, formatting, ownership, and triage feedback. Pull requests could also define workflow changes that executed before those definitions were merged into trunk. The selected-actions policy prevented the external Codex action from running. Solution: ========= Add structured issue and pull request templates, CODEOWNERS-based review routing, path-based area labels, and an expanded contributor guide while preserving the existing non-code contribution terms. Add scripts/ci helpers for Ubuntu toolchain setup, Ninja and ccache builds, clang-format, and the default MTR test selection. Run automatic PR automation from trunk with pull_request_target. Verify PR merge parents, disable persisted checkout credentials, scope permissions per job, restore caches without saving PR-controlled data, and execute build and MTR helpers from the trusted base SHA. Build Debug configurations with GCC and Clang, run default MTR with six-hour limits, publish statuses on the PR head, assign code owners after OCA verification, reconcile approved PRs daily, and apply PR-only stale handling.
