From 3005815fe41f983a9d21b4111777674ff75c3754 Mon Sep 17 00:00:00 2001 From: magdev Date: Sat, 2 May 2026 20:01:52 +0200 Subject: [PATCH] Phase 4a sub-commit 5: performance-smoke harness + 4a closure MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit examples/todo/tests/perfsmoke.sh asserts the PLAN.md §11 budgets against the built AppImage: - Bundle size ≤ 200 MB (hard cap; ≤ 120 MB target) - Cold start ≤ 2000 ms from launch to first /healthz 200 - Idle RSS (host + descendants in the process group) ≤ 200 MB after a 2 s settle. Each budget is overridable via env (PERF_COLD_START_MS etc.) for slow shared CI runners; defaults are the strict numbers from the plan. Runs the AppImage under xvfb-run when DISPLAY is unset; falls back to QT_QPA_PLATFORM=offscreen otherwise (the build script already bundles libqoffscreen.so via EXTRA_PLATFORM_PLUGINS). Wired into: - examples/todo/Makefile → `make perf` - .gitea/workflows/release.yml → runs after AppImage build, before zsync + upload, with cold-start budget bumped to 4 s for CI. CI now also installs zsync + xvfb in one step. examples/todo/README.md gains an "AppImage packaging (Phase 4a)" section walking through `make appimage`, bundled-mode behaviour, the auto-update QML hooks (BackendConnection.checkForUpdates() / applyUpdate()), and `make perf`. PLAN.md §13 Phase 4 marked **4a closed**. 4b (macOS) and 4c (Windows) stay stubs until their runners + certs exist.
