78a6648c8d perf(electron): let hidden and minimized windows report themselves hidden (#1724)
* perf(electron): let hidden and minimized windows report themselves hidden

The main window was created with backgroundThrottling: false (since #1123,
without a stated reason). Electron then keeps document.visibilityState at
"visible" for a hidden, minimized or fully covered window and never lets
Chromium throttle it, so every renderer timer, rAF and CSS transition ran at
full rate in the background, and the playback keep-awake gate, which
releases the display for a minimized window, could never see one.

Use Chromium's default. Audible media and picture-in-picture are exempt
from background throttling in Chromium, and a local check confirmed HLS
playback continues unchanged through more than six minutes minimized,
audible and muted.

Playwright's focus emulation pins every page it attaches to as visible, so
the new window-visibility E2E launches the app without Playwright and
drives it over raw CDP (electron-unautomated-launch.ts).

* test(e2e): harden the unautomated Electron launch

Review follow-ups for the window-visibility E2E:

- Resolve `electron` in the main process through a require created from
  the `node:module` builtin instead of `process.mainModule`, which only
  exists when the app entry is CommonJS.
- Bound teardown like closeElectronApplicationAndConfirmExit: SIGTERM,
  then SIGKILL, 5 s each, then fail instead of waiting forever.
- Surface CDP protocol errors from Runtime.evaluate instead of returning
  undefined.
- Wait until the window is actually shown before hiding it. The app shows
  its window on ready-to-show, and a hide() that lands earlier is undone
  by that show(); this was the first-attempt failure on the macOS shard.

* test(e2e): check the playback display lock is released while hidden

Review follow-ups for #1724:

- Add an E2E that plays the webm fixture in the unautomated launch,
  records the main process's prevent-display-sleep blockers, and asserts
  the keep-awake lock is taken while visible, released when the window is
  hidden, and taken again when it is shown. The visibility tests alone
  would still pass if the renderer gate or the bridge stopped updating
  powerSaveBlocker.
- Validate CDP replies before dispatch (CodeQL
  js/unvalidated-dynamic-method-call): only a numeric id with a pending
  settle function is called.

* test(e2e): skip killing an Electron that already exited

stopElectron now checks the recorded exit state before each signal and
tolerates a kill that races the exit: on Windows taskkill throws for a PID
that no longer exists. Startup cleanup can no longer replace the startup
error that explains the failure; a cleanup failure there is logged.

* fix(stalker): keep the watchdog cadence while the window is hidden

With background throttling on, Chromium wakes a hidden, silent page's
timers at most once per minute after five minutes, so a portal that asks
for get_events every 30 s would see pings at half its cadence while the
window is minimized. Tick the watchdog from a dedicated worker
(createBackgroundInterval, an inline blob worker allowed by the renderer
CSP), whose timers are not subject to page throttling. It falls back to a
page setInterval where no worker is available or the worker fails to load.

* fix(stalker): keep a stopped watchdog interval stopped

A worker error that arrived after stop() started the page fallback
interval, which nothing cleared, so pings continued for an inactive
playlist. stop() now marks the interval stopped, detaches the worker
handlers, and the fallback refuses to start afterwards.

Release notes (.changes/)

Every PR with a user-visible change drops one file here describing that change in plain language. At release time tools/release/build-release-notes.mjs turns the accumulated files into the GitHub release body, the CHANGELOG.md section, a blog-post scaffold for the website, and Telegram/Reddit announcement drafts — then deletes them.

The point is to write the note while the context is still fresh, instead of reconstructing three months of work from commit titles at release time.

File

Name it <area>-<short-slug>.md, e.g. .changes/playback-up-next-rail.md.

---
type: feature
area: playback
issues: [1187]
screenshot: up-next-rail
highlight: Up Next rail
---

Series now show an "Up Next" rail beside the player on wide windows: the rest
of the current season, watch progress, and click-to-play inline.
Field Required Value
type yes breaking, feature, fix, perf, or internal
area yes lowercase slug, same as the conventional-commit scope
issues no issue numbers this closes — [1187] or 1187
screenshot no slug from tools/release/screenshots.manifest.json
highlight no short headline (max 60 chars) marking a release highlight

There is no version field. The release version is chosen deliberately at release time, not derived from these files.

You never write a PR number: the generator resolves it from the commit that added the file.

Writing the body

One to three sentences, present tense, written for a user, not a reviewer. The body is capped at 400 characters — depth belongs in the blog post.

  • ❌ "Refactor WebVideoControlsAdapter to hoist volume state into the session"

  • ✅ "The player now remembers volume between episodes"

  • ❌ "Fix off-by-one in resolveEnrichmentSeasonNumber"

  • ✅ "Series whose title carries a season marker no longer show the wrong season"

highlight marks the change as one of the release's headline features and gives it a short, poster-worthy name. The 60-character cap keeps it roughly to one line on the hero card; card text wraps by estimated width, so a headline of unusually wide glyphs may still wrap or ellipsize rather than overflow. Highlights lead the Telegram/Reddit announcements (everything else collapses into a "+N more" counter) and open the blog scaffold: a row in its "What changed" table and a ## section ahead of the themed sections, while fixes without a highlight collapse under a spoiler there. Set it on the two or three changes worth announcing — a release where everything is a highlight has none. Not allowed on type: internal.

type: internal records invisible maintenance. Internal notes stay collapsed in CHANGELOG.md, are omitted from the blog scaffold, and are removed from the authored public GitHub body by extract-changelog-section.mjs --public. GitHub's generated commit list remains separate. An internal-only release can therefore have an empty authored body.

When a note is not needed

The gate auto-exempts website, E2E and mock-server apps, *.spec.{js,ts}, *.e2e.{js,ts}, snapshots, any /testing/ path, and Markdown. For other test-only, documentation, CI/workflow, or pure-refactor changes under apps//libs/, apply no-release-note when no user-visible note is warranted.

Commands

pnpm run release:notes:validate
pnpm run release:notes:github
pnpm run release:notes:changelog
pnpm run release:notes:blog
pnpm --silent run release:notes:telegram
pnpm --silent run release:notes:reddit
node tools/release/build-release-notes.mjs --consume

The release version comes from the root package.json — bump it first, then generate. --version 0.24.0 overrides it to preview a release before the bump:

pnpm run release:notes:github --version 0.24.0

A bare -- separator is accepted and ignored, so the npm habit of pnpm run release:notes:github -- --version 0.24.0 works too: pnpm forwards that separator to the script rather than consuming it the way npm does.

--validate, --format github, --format telegram, and --format reddit only read and print. --format changelog and --format blog write their target file (rerunning changelog for the same version replaces that section rather than duplicating it). Only --consume deletes anything.

The announcement formats print paste-ready posts to stdout, each guaranteed to fit its platform's limit: Telegram plain text within 4096 characters, Reddit markdown within 40,000, with a suggested post title on the first line. Whatever does not fit collapses into a counter; a breaking change is never collapsed, and if the highlights alone will not fit, the render fails with an actionable error rather than shipping a post that cannot be submitted. Use pnpm --silent run for these two — plain pnpm run prints its lifecycle banner to the same stdout, so a redirected post starts with two lines of build noise. Render and save them before --consume — the changelog keeps the entries, but the highlight: metadata lives only in the note files. Publishing is manual; nothing posts anywhere. An internal-only release has nothing to announce: both formats then print an explanation on stderr, leave stdout empty, and exit 0 — the same shape extract-changelog-section.mjs --public uses for its empty public body.

The release sequence is: bump the version → release:notes:changelog → release:notes:blog → release:screenshots → release:notes:telegram / release:notes:reddit → release:cards:generate → --consume → commit → tag → push → release:verify:draft. Everything reading highlight: comes before --consume, because that step deletes the only copy of it. Full contract: docs/architecture/release-pipeline.md. The tag build then extracts the new CHANGELOG.md section into the GitHub release body (tools/release/extract-changelog-section.mjs) and fails the release if the section is missing — a tag cut without the changelog step cannot silently ship PR-title-only notes.

The website publishes one post per minor version (v0-18 … v0-22), and release screenshots live under the matching blog/v0-24/ directory. A patch release therefore edits the existing post rather than generating a new one, so --format blog refuses to overwrite unless you pass --force.

Screenshots

pnpm run release:screenshots captures every manifest shot in dark and light against the built app plus the Xtream mock server — never a real account. The run is fail-closed: it proves the real ~/.iptvnator/databases directory (including the SQLite WAL sidecars, checked after Electron exits) was not touched, launches the app with an allowlisted environment, records and blocks all non-localhost traffic, scans every frame for external resources and credential-shaped text, and asserts TMDB enrichment stays disabled. Frames are staged outside the repository and published only once every shot and every guard has passed.

Adding a shot for a new feature = one entry in tools/release/screenshots.manifest.json (plus, if navigation is new, one named action in tools/release/capture-navigation.ts).

Highlight cards

pnpm run release:cards:generate renders one branded 1200×630 card per highlight: note (headline, body, and a framed screenshot strip when the note names one) plus a release hero card — for Telegram/Reddit previews and the blog hero.jpg. It reads screenshots from the published blog directory, so it runs after release:screenshots and, like the announcement formats, before --consume. Output goes to dist/release-highlight-cards/v<version>/, and a rerun replaces the cards it previously wrote there; copying a card into the website tree is a deliberate manual act. release:cards:dry-run lists what would be rendered. A release without highlights still gets its hero card, and an internal-only release writes nothing — neither is an error.

pnpm nx run electron-backend:build-e2e   # once, before capturing
pnpm run release:screenshots             # all shots, both themes
pnpm run release:screenshots -- --only dashboard --theme dark
pnpm run release:screenshots -- --release v0-24
