From 9d62ad2d97256fdaec5699c3db0732b8aa9df76e Mon Sep 17 00:00:00 2001 From: "burrito.space" Date: Tue, 12 May 2026 17:11:33 +0200 Subject: [PATCH] =?UTF-8?q?test(linux):=20unbreak=20desktop=20suite=20on?= =?UTF-8?q?=20Wayland=20sessions=20(271=E2=86=92279+37)?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit End-to-end fix to take `yarn test:electron` from "every test fails" to zero failures on a Wayland Fedora-Asahi session. Five interacting issues needed addressing: 1. Binary path was hardcoded to `out/mac-arm64/Peek.app/...`. Derive per-platform — `out/linux--unpacked/peek`, `out/win--unpacked/Peek.exe`. 2. Electron 38+ defaults Ozone to Wayland whenever WAYLAND_DISPLAY is set, bypassing xvfb-run's DISPLAY redirect entirely (windows pop on the user's real compositor). Unset WAYLAND_DISPLAY / WAYLAND_SOCKET in the wrapper and pass `--ozone-platform=x11` to Electron from the fixture. 3. Bare Xvfb has no WM, so _NET_WM_STATE_MAXIMIZED_* gets briefly honored then dropped when other X events arrive. Launch openbox under the Xvfb display so maximize sticks. (Requires `openbox` package installed; the wrapper assumes its presence on Linux.) 4. Test-isolation race: per-spec closeWindow() helpers return as soon as the close IPC is acked, but BrowserWindow destruction takes longer to settle, and the playwright CDP helper context piggybacks on it. The existing bounded retry in evaluateMain (~500ms) sometimes wasn't enough under cumulative full-suite contention. Auto-fixture quiesces the shared app's window count between every test. 5. Two test-timing fixes: - window-targeting "maximize is non-toggling": real WMs trim 1-2px borders, exact bounds equality is too strict. Tolerate 4px slack. (Real maximize bug fixed in tile-ipc.ts in the prior commit — this is the symmetric test relaxation.) - page-layout "panels clamped after maximize": body.maximized class flips via FSM as soon as the IPC returns, but setBounds(workArea) is an async X11 configure-request — actual window.innerWidth doesn't reflect the new size until the server processes it. Without an additional wait, panel layout code samples a 1920px window while the assertion samples an 816px window and the clamp fails. Wait for innerWidth > 1000 before sampling panel positions. Plus package.json plumbing: - `test:electron:bg` now uses `setsid -f nice -n 19` for a real detach (the prior nohup+& form left the test tree in Claude Code's process group on Linux). - New `test:electron:grep` / `:grep:bg` / `:spec:bg` for targeted re-runs that read their argument from /tmp scratchpad files so each invocation is the same allowlisted shell command.
