What

Five small bugs found while preparing 1.8.2. Each one was checked in the code before fixing. There is one commit per fix, so each gets its own changelog line.

Smart playlists offered in "Add to playlist"

A smart playlist is rebuilt from its rules. upsert_smart_playlist deletes its playlist_track rows before inserting the new set. So a track added by hand was accepted, shown, then dropped at the next regeneration.

  • Four lists offered smart playlists. All four now show regular playlists only:
    • the track context menu;
    • the selection bar;
    • AddToPlaylistPopover in LibraryView;
    • the folder menu in LibraryView.
  • add_track_to_playlist, add_tracks_to_playlist and add_source_to_playlist now refuse a smart playlist (refuse_smart_playlist, run inside the transaction). This covers every other way in.
  • smart-playlists.md promised a "Save as new playlist" action that does not exist. It now says what the app does. Freezing a mix into a playlist is a 1.9 draft.

LRC with every line on one time counted as synced

lyrics_are_synced accepted any LRC with a single complete stamp. Some sources stamp every line [00:00.00]. Such an answer ended the lyrics waterfall ahead of real timing, and the renderer lit only its last line.

  • Backend: lrc_has_timing replaces lrc_has_line_stamp. When more than half of the sung lines (a stamp followed by text) share one time, the lyrics are untimed. Stamps are normalised like the frontend's lrcStampToMs, so [00:01.5] and [00:01.500] count as one time.
  • Frontend: isUntimedLrc applies the same rule. useTrackLyrics then hands such lyrics out as a plain payload with the stamps stripped. Every surface already renders plain text, so no view changed.
  • Tests: these cases are covered:
    • everything on 0;
    • a title card at 0 followed by real timing (stays synced);
    • lines piled on another time;
    • mixed precision;
    • exactly half (stays synced);
    • stamps with no text.

Shift+click with no anchor

selectRange used the clicked row as the anchor when there was none, but never stored it. After clear(), which single-click play calls on every play, two Shift+clicks selected two lone rows. The same happened when the anchor row had been filtered out. Now the click becomes the anchor in both cases.

"Ma musique" hard-coded

Four paths created the first library as "Ma musique" whatever the UI language:

  • Sidebar;
  • HomeView;
  • LibraryView;
  • the drag-and-drop import.

They now use onboarding.defaultLibraryName, which onboarding already uses and which is translated in all 17 locales.

Offline radio tag filter

The tag: filter built LIKE '%' || ? || '%', so a % or _ in a tag matched anything. It now binds core's like_pattern with ESCAPE '\', as library search does.

Checks

  • bun run typecheck and eslint on the touched files pass.
  • cargo fmt --check passes.
  • cargo clippy -p waveflow --all-targets -D warnings passes on Windows.
  • The new Rust tests are left to the Ubuntu job, since the app crate's test binary cannot start locally on Windows.
  • Local CodeRabbit review: 0 findings.

@coderabbitai review

Summary by CodeRabbit

  • Améliorations

    • Les paroles LRC dont plus de la moitié des lignes chantées partagent le même horodatage sont reconnues comme non synchronisées, sauf si les horodatages des mots indiquent plusieurs instants distincts.
    • La recherche de stations par tag traite « % » et « _ » comme des caractères littéraux.
    • Le nom des bibliothèques créées lors d’un import s’adapte à la langue de l’application.
    • La sélection d’une plage fonctionne aussi lorsque son point d’ancrage n’est plus disponible.
  • Corrections

    • Les playlists intelligentes ne sont plus proposées comme destinations d’ajout, et les commandes d’ajout les refusent. Le retrait de morceaux reste possible jusqu’à la prochaine régénération.
    • Les menus indiquent lorsqu’aucune playlist régulière n’est disponible. La conversion d’une playlist intelligente en playlist régulière n’est pas encore proposée ; pour conserver une curation manuelle, créez une playlist régulière.
    • Les paroles LRC non synchronisées sont présentées sans horodatage.

A smart playlist is rebuilt from its rules, so a track added to it by
hand showed up and then vanished at the next regeneration. The four
add-to-playlist lists now offer regular playlists only, and the three
add commands refuse a smart one.
Some sources stamp every line [00:00.00]. One stamp was enough to call
such lyrics synced: they ended the search for real timing, and only
their last line lit up. When more than half of the sung lines share
one time, the backend keeps looking and the panels show plain text.
After the selection was cleared, which single-click play does on every play, two Shift+clicks selected two lone rows and never the range between them.
Four paths created the first library as "Ma musique" whatever the language. They now use the name onboarding already gives it.
A % or _ in a tag matched any text in the offline catalogue.

Priority: ➖ Normal

Estimated code review effort: 3 (Moderate) | ~20 minutes

Change: Bug fix

Merge Risk: ⚪ Minimal · up to ca1d6

The changes are small and independent: lyric timing classification, smart-playlist add refusal, literal tag-search wildcards, translated library names and a range-selection anchor fallback. No outstanding merge-blocking issue was found; the Rust tests still need to pass in CI.

Security Architecture Review

Security architecture risk: 🔵 Low · up to ca1d6

The changes reinforce existing playlist ownership rules and correct lyric selection without adding new endpoints or privileges. No introduced security issue was established, but database concurrency and recovery behavior were not fully validated.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

  • inferred — The changed playlist guard acts on caller-selected playlist IDs within the leased active-profile database. It enforces playlist type, not authentication or tenant ownership, and does not itself grant access to another database or service.

Trust Boundaries and Controls

  • observed — Bypassing frontend playlist filtering does not bypass the new type restriction in the three changed add commands: each independently reads the persisted playlist flag and refuses smart-playlist insertion before mutation.
  • inferred — Provider-controlled lyric text can affect timing classification and which existing fallback provider is consulted. The inspected change alters content precedence and display behavior, not command identity, plugin authority, or a demonstrated privileged sink.

Resilience and Maintainability Implications

  • inferred — Smart-playlist refusal exits before membership writes or post-commit effects, preventing the previously accepted-then-discarded addition. Ordinary playlist insertion retains its existing duplicate-skipping behavior. This supports containment of the changed rejection path, but does not establish all concurrency or recovery guarantees.

Enhanced LRC words stamped at two or more times carry the karaoke even when every line sits on one time, so the untimed rule no longer turns them into plain text. The smart-playlist doc now says removals are still allowed and last until the next regeneration.

@coderabbitai Thanks, both findings checked against the code. Addressed in the latest commit.

docs/features/smart-playlists.md: valid. remove_track_from_playlist does not refuse a smart playlist, and that is intended. The section now separates the two cases:

  • adding is refused, because the track would be accepted and then vanish;
  • removing is still allowed, from the track menu and the selection bar, and lasts until the next regeneration.

Enhanced LRC in lrc_has_timing / isUntimedLrc: valid. Lyrics whose lines are all stamped on one time but whose words are stamped at real times would have been flattened to plain text, losing their word timing.

  • Enhanced LRC word stamps at two or more different times now count as timing on both sides: LRC_WORD_STAMP in Rust, and line.words in the frontend. In that case the untimed rule does not apply and the structure is kept.
  • There is a new test for it, and integrations.md mentions it.

Not done: changing findActiveLineIndex to choose the active line from word timestamps when lines share a stamp. Such files already behaved like that before this PR, so it is not a regression introduced here. It is a renderer improvement for an unusual file shape, not a fix, and stays out of this patch release.

@InstaZDLL Merci pour les précisions. La lecture du dernier code confirme les deux corrections :

  • smart-playlists.md distingue bien l’ajout refusé du retrait autorisé jusqu’à la prochaine régénération.
  • lrc_has_timing et isUntimedLrc préservent les paroles Enhanced LRC dès que les horodatages des mots comportent au moins deux instants distincts.

Les deux constats sont donc traités. Je n’ai pas exécuté les tests.

Je respecte le périmètre de cette version corrective pour findActiveLineIndex. Souhaites-tu ouvrir une issue de suivi pour cette amélioration du rendu ?

Ignorez les horodatages Enhanced LRC sans texte.

Quand une ligne contient seulement des stamps, isUntimedLrc ajoute tout de même leurs temps à wordTimes. Avec [00:00]<00:01><00:02> suivi de deux lignes chantées à [00:00], la fonction renvoie false. useTrackLyrics conserve alors ces lignes comme synchronisées, même si aucun mot ne possède de texte. Filtrez les segments vides avant d’ajouter leur temps.

@coderabbitai Both valid, fixed in the latest commit.

  • lrc_has_timing: a word stamp now counts only when non-blank text follows it, up to the next stamp or the end of its line. The stamp that closes an Enhanced LRC line marks where the line ends, not a word. Before this, end markers at different times let words piled on one time pass as synced. The distinct-time check is unchanged: two or more qualifying stamps are needed.
  • isUntimedLrc: words with blank text are skipped the same way, so both sides apply the same rule.

Tests: closers covers words piled on 0 with end markers at 5 s and 6 s, which stay untimed. An inverse case covers real word timing with the same kind of end markers, which stays synced.

Text before a line's first word stamp is a word sung at the line's own time in parseEnhancedLrc. The backend ignored it, so the two sides could disagree on whether such lyrics are synced.

@coderabbitai Valid, fixed in the latest commit.

lrc_has_timing now reads each line the way parseEnhancedLrc does:

  • lines without a line stamp are skipped;
  • word stamps are found in the body once the line stamps are removed;
  • non-blank text before the first word stamp counts as a word sung at each of the line's own times.

The two sides used to disagree on, for example, [00:00.00]a <00:05.00>b repeated on two lines. The frontend saw words at 0 s and 5 s and called the lyrics synced. The backend saw 5 s only and called them untimed. The new prefixed case in the test covers exactly that.

@InstaZDLL Merci pour les précisions. La lecture du code confirme la correction :

  • lrc_has_timing ignore les lignes sans horodatage de ligne.
  • La fonction retire les horodatages de ligne avant de chercher les horodatages de mots.
  • Le texte non blanc avant le premier horodatage de mot compte à chaque instant de la ligne, comme dans parseEnhancedLrc.
  • Le test prefixed vérifie que les mots à 0 s et 5 s conservent la classification synchronisée.

Le constat est traité. Je n’ai pas exécuté les tests.

Learning: Dans WaveFlow, src-tauri/crates/app/src/commands/lyrics.rs::lrc_has_timing doit interpréter les mots Enhanced LRC comme src/lib/tauri/lyrics.ts::parseEnhancedLrc : ignorer les lignes sans horodatage de ligne, retirer les horodatages de ligne avant de chercher les horodatages de mots, et compter le texte non blanc avant le premier horodatage de mot à chacun des instants de la ligne. Le test prefixed couvre deux lignes horodatées à 0 s avec un préfixe chanté à 0 s et un mot horodaté à 5 s ; ces paroles restent synchronisées.

Learning: Dans WaveFlow, les horodatages Enhanced LRC de fermeture de ligne ne représentent pas des mots et ne doivent pas contribuer au décompte des instants distincts. Dans src-tauri/crates/app/src/commands/lyrics.rs::lrc_has_timing, un horodatage de mot compte seulement si du texte non blanc le suit jusqu’au prochain horodatage ou à la fin de la ligne. Dans src/lib/tauri/lyrics.ts::isUntimedLrc, les mots dont le texte est blanc sont ignorés. L’exception qui préserve la synchronisation Enhanced LRC exige au moins deux instants distincts parmi ces horodatages admissibles.

Timestamp: 2026-10-05T06:52:01.061Z
Learning: Dans WaveFlow, les paroles Enhanced LRC dont les lignes partagent un horodatage doivent conserver leur structure si les mots portent au moins deux instants distincts. src-tauri/crates/app/src/commands/lyrics.rs::lrc_has_timing et src/lib/tauri/lyrics.ts::isUntimedLrc appliquent cette exception. Le choix de la ligne active selon les horodatages des mots dans findActiveLineIndex est une amélioration du rendu préexistant, hors du périmètre de la version corrective 1.8.2 et de la PR #804.
