Third of four PRs for the music player: connecting Spotify through the person's own Web API app. Without a connection everything works as before, through the local app.

  • /glowup spotify connect (or k in the music dialog) walks through creating a developer app and pasting its Client ID, then runs glowup-installer spotify-login: PKCE, a loopback callback on 127.0.0.1, and a paste field for when the browser is on another machine. No client secret.
  • The token file is written only by the Go helper, atomically, at mode 0600. spotify-refresh holds an O_EXCL lock and a generation counter, so two sessions refreshing at once make one network call. spotify-logout takes the same lock, so a refresh in flight can't write a token back after disconnect.
  • When connected, the Web API runs the player: the heart (l), Up next on the tab, and shuffle, repeat and volume on Linux too. (local) shows while the API isn't answering and the local app is used. A write falls back to the local app only on a 429; after a 5xx, a timeout or a busy endpoint the person sees "Spotify is not answering right now", because the write may have landed and a local fallback would apply it twice.
  • A hung API request keeps its endpoint busy until the engine finishes it, so polls can't pile up. Liked state and the queue are read once per track.
  • A token file from a newer glowup is refused and never refreshed or overwritten; a damaged one says so and can be replaced by connecting again.
  • /glowup spotify shows the connection; /glowup spotify disconnect removes the token file.

Known limit, documented in docs/spotify.md: the engine gives the mod no way to kill a child's process group, so after Cancel the login helper can live up to five minutes, and agreeing in the browser in that window still connects. Each login gets its own paste file, so a lingering helper can't take the next login's address.

Checked live in tmux with a stand-in xdg-open (no browser opened, Spotify not running): /glowup spotify unconnected, the tab and dialog without a connection, the connect steps, Copy address, the bad Client ID error, the waiting step, the paste field taking the keyboard, Cancel and Escape ending the helper. Not checked yet, because they need a Spotify developer app: login, refresh, the heart, Up next and the API's art host (#51).

Summary by CodeRabbit

  • New Features
    • Connect a Spotify Premium account to control playback across devices, like tracks, and view the next queued track and active device.
    • Use Spotify playback controls on Windows. On other platforms, controls use Spotify when connected and fall back to the local player when needed.
    • Manage Spotify connection status, connect, or disconnect with the /glowup spotify command.
  • Documentation
    • Added a Spotify connection guide with setup, account requirements, and troubleshooting information.

Walkthrough

The change adds Spotify account connection and Web API playback alongside local playback. It adds token and login commands, routes playback controls between Spotify and the local app, and updates the player, music pane, help, and documentation.

Changes

Spotify playback and API

Layer / File(s) Summary
Playback contracts and Web API
hooks/music/parse.ts, hooks/music/player.ts, hooks/music/spotify.ts, hooks/music/webapi.ts, test/music-*.test.ts
Music state now includes optional Spotify source, device, liked-track, and queue data. Web API requests, response parsing, error handling, playback-state merging, and command routing are added, with tests for parsing, refresh, polling, and fallback behavior.
Credential lifecycle and installer commands
hooks/music/tokens.ts, installer/internal/spotify/*, installer/main.go
Token files can be read, written, refreshed, and removed. The installer adds PKCE login through a loopback callback or paste file, plus spotify-login, spotify-refresh, and spotify-logout commands.
Host and runtime wiring
hooks/host.ts, hooks/launch.ts, hooks/register.tsx, hooks/command.ts, test/spotify-wiring.test.ts, test/spotify-kit.ts, test/kit.ts
The host adds timed HTTP and subprocess support. Runtime wiring polls Spotify, merges its state with local playback, routes controls, and handles connect and disconnect actions.
Player UI and documentation
hooks/musicplayer.tsx, hooks/pane.tsx, hooks/music/reader.ts, docs/*, CHANGELOG.md
The player adds account setup and connection states. The music pane can show like status, the next track, playback device, and local playback attribution. Help and documentation describe setup, commands, requirements, and fallback behavior.

Merge Risk: 🔵 Low · up to a4455

The Spotify connection is optional, and local playback is unaffected. One failed request can hide the heart or Up next until the track changes. A refresh running in another session can occasionally undo a new login, and connecting again recovers it. The change is mergeable, with these as small follow-ups.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Clear the in-flight key when a like or queue read fails.

readLiked sets link.liked = { uri } before the request. When the read fails, the function returns and leaves that key in place. pollApi then skips readLiked for this track, because link.liked?.uri === uri. One transient error (a timeout or a 5xx) therefore hides the heart for the whole track. readQueue has the same behavior for Up next while the dialog is in sight. The code comment says this is intended for likes. For a queue that only needs one retry, the cost is the same. Reset the key when the read fails and still targets this track. A later poll can then retry it.

Proposed fix
   const on = a.ok ? parseLiked(a.text) : undefined
-  if (on === undefined || s !== spotify || link?.liked?.uri !== uri) return
+  if (s !== spotify || link?.liked?.uri !== uri) return
+  if (on === undefined) { if (!a.ok && link.liked.on === undefined) link.liked = undefined; return }

🗄️ Data Integrity & Integration | 🟡 Minor | ⚡ Quick win

Take the token-file lock before login writes the token file.

Refresh and LogoutMain hold lockFile(path) for their whole read-modify-write. finish calls WriteTokens without that lock. The race works like this:

  1. Another session's spotify-refresh reads the old file (for example, Gen: 5).
  2. That refresh sends its token request.
  3. The login writes the new account's tokens with Gen: 1.
  4. The refresh then writes the old account's tokens with Gen: 6.

The new connection is lost without any error, and the old login comes back. A user who connects again while an earlier connection is refreshing can hit this. Take the same lock around the write.

lockFile returns ErrNotExist when the directory is missing. WriteTokens creates the directory, so create it with os.MkdirAll(filepath.Dir(l.Out), 0o700) before you call lockFile.
