The interface for playing files without importing them (the engine landed in #927), and a drop import that no longer registers the folder the files came from.

Play without importing

  • A drop has two targets, Play now and Add to the library, side by side while files are dragged over the window. The pointer picks one: Tauri's physical position is divided by devicePixelRatio and tested against the targets' own boxes, so a right-to-left layout needs no special case and the gap goes to the nearer target.
  • Sidebar: a Play without importing button in the My music header opens a menu with Play files… and Play a folder…, also bound to Ctrl+O and Ctrl+Shift+O (rebindable, allowed from a text field, held keys do not stack dialogs).
  • The overlay is portalled to document.body. It keeps a visible ring in the classic skins, where the card is restyled as a panel. On the fluid layout (Fluid, Liquid) it is recomposed through data-drop-* landmarks: surface cards, the accent edge and the wave mark under the hovered target.
  • The full-screen Importing… overlay is gone: it hid the app, and the task status bar that shows and stops the scan, for as long as the scan ran. That was minutes for a whole music folder.
  • The like shortcut no longer acts on a track without a library row.

Add to the library copies into a managed folder

Dropping one file used to add its parent folder to the library. Dropping a file from Music added all of Music, on top of the folders already there (thousands of tracks, every scan reading the shared files again). Now:

  • dropped files are copied into WaveFlow under the user's music folder (dirs::audio_dir, else ~/Music; the Flatpak already has xdg-music read-write). That folder is the library folder, and the originals stay where they are.
  • As they are: a folder keeps its name and tree and brings its covers (the scanner's own FOLDER_COVER_EXTENSIONS) and lyrics sidecars; a file goes to the root with its same-name .lrc.
  • An item already under a library folder is passed over. A folder holding one is refused: it would duplicate tracks, and the music folder would copy into itself.
  • No second copy: the same name and size count as already copied, and another size gets name (2).ext. Writes go through .waveflow-part and a rename. Already-copied files are still scanned, in case their folder left the library.
  • Limits: at most 20 000 files per drop. The copy is a drop_import task in the status bar, stoppable between files.
  • ImportNoticeToast (bottom centre) summarises what was copied, skipped, refused or failed. A notice that needs attention stays until dismissed.

import_paths is replaced by import_dropped.

Library folders never overlap

add_folder_to_library now refuses a folder that is, lies under or holds a folder already in any library of the profile, with AppError::FolderOverlap.

  • Why: a folder owns its tracks through track.folder_id, so two nested folders both claim the shared files, and removing either could delete tracks the other still shows.
  • Comparison: the paths are compared by name with waveflow_core::scanner::folders::relation: ./.. resolved, case ignored on Windows and macOS, never a string prefix.
  • What the user sees: the frontend reads the folder in the way from the error message and shows it once, from LibraryContext.importFolder, which covers the sidebar, Home, Library and onboarding.
  • Docs: the rule is added to invariants.md and CLAUDE.md.

Checks

  • typecheck, lint, cargo fmt --check and cargo clippy --workspace --all-targets pass.
  • Tests:
    • scanner::folders: 4 tests, run locally.
    • drop_import: 5 tests, run locally in a throwaway crate; the app crate's test binary does not start on Windows, so CI ubuntu runs them for real.
  • Checked by hand in a sandboxed debug build over CDP:
    • hover and drop routing;
    • the sidebar menu;
    • the Fluid, Liquid and Pulse skins;
    • one drop of an album, a file, a library folder and the whole music folder: 4 copied, 1 skipped, 1 refused, and only Music/WaveFlow scanned;
    • the same album dropped again: nothing new, already copied;
    • the three overlap refusals, including a different case and a trailing separator.
  • The local CodeRabbit review is clean: its two findings are applied (scan already-copied files; reuse the scanner's cover extensions).

Summary by CodeRabbit

  • Nouvelles fonctionnalités

    • Le glisser-déposer permet désormais de lire immédiatement ou d’importer des fichiers dans WaveFlow.
    • Les imports préservent l’arborescence, les pochettes et les fichiers associés, tout en gérant les doublons.
    • Ajout des raccourcis Ctrl+O et Ctrl+Shift+O pour lire des fichiers ou un dossier sans importation.
    • Des notifications détaillées indiquent le résultat des imports.
  • Corrections

    • Les dossiers qui se chevauchent sont refusés et signalés clairement.
    • La lecture sans importation prend en charge les extensions audio compatibles.

…and ctrl+o

A drop on the window now offers two targets, play now or add to the library, picked by the pointer against the targets' own boxes. The sidebar's my music header gains a play without importing menu (files or a folder), bound to Ctrl+O and Ctrl+Shift+O. The overlay is portalled, keeps a visible ring in skins that restyle it as a panel, and follows Fluid Editorial in the fluid skin.
…ull-screen overlay

Dropping a whole music folder kept a blurred importing screen over the app for the minutes its scan took, hiding the task status bar that already shows and stops that scan.
…erlapping library folders

A drop on add to the library used to register the folder the files came from, so dropping one file from Music added all of it. The files are now copied into WaveFlow under the user's music folder, which is the library folder; items already in the library are passed over and folders holding one refused. Adding a folder that is, lies under or holds a library folder is refused with a toast naming the folder in the way.
…d folder

The drop's sidecar list knew jpg, png and webp only, so a folder.bmp or cover.gif stayed behind. It now reuses the scanner's FOLDER_COVER_EXTENSIONS.

Merge Risk: 🟡 Moderate · up to 35868

After importing a drop, users cannot add their Music folder to the library without first removing the managed folder’s library tracks. Resolve or explicitly accept that workflow limitation before merging.

Security architecture risk: 🟡 Moderate · up to 35868

The new import flow limits accidental imports and protects ordinary copies from partial writes. However, concurrent imports can create conflicting ownership of the managed folder, and pre-existing symbolic links can redirect writes outside it. The latter requires access to the managed directory; no remote exploit or privilege escalation was established.

Retained concerns

  • Medium · reliability · inferred: Managed-folder ownership is selected before copying and inserted afterward without shared lifecycle serialization. Two imports into different libraries can both observe no owner, copy unrelated inputs into the same WaveFlow directory, and create separate folder rows for that directory. The file-copy lock does not cover this transition, and database uniqueness is only per library. This undermines the new single-owner invariant and exposes library records to conflicting scans and folder removal. Unlike the base flow, unrelated source folders now converge automatically on one destination.
  • Medium · security · inferred: The new writer copies into a predictable target.waveflow-part path without exclusive creation or symlink rejection. On systems that follow destination symlinks, an actor able to pre-place that entry can redirect a subsequent legitimate import into another application-writable file before the rename. Symlinked destination parents also lack a confinement check. Ordinary path construction and the process-wide lock do not prevent pre-existing filesystem redirection. This is a conditional local integrity concern, not an established remote attack or elevation of privilege.
Security review details

Security Blast Radius

  • inferred — The supported exposure is the desktop application's accessible filesystem and active profile's library records. A redirected write cannot exceed the process's filesystem authority. The evidence does not establish a remote actor capable of planting managed-directory links, cross-user privilege escalation, or cross-tenant access.

Security Findings and Attack Paths

  • inferred — A conditional integrity path is pre-placement of a destination temporary-file symlink followed by a legitimate drop selecting that filename. The new copy operation can follow the link before rename. The lock prevents competing application imports from choosing the same temporary name, but does not authenticate a pre-existing directory entry.

Trust Boundaries and Controls

  • observed — For ordinary paths, destination construction uses the fixed managed root plus a filename or source-relative tree, rather than an arbitrary renderer-supplied destination. Planning bounds primary copies and visited entries, filters supported content, skips reserved directories, and checks cancellation. These controls limit accidental expansion but do not replace symlink-safe writes.

Resilience and Maintainability Implications

  • inferred — Concurrent removal can also invalidate the indexing-folder snapshot during a long copy. The subsequent scan rejects the deleted folder ID, leaving completed files on disk without the intended indexing transition. Repeating the import provides a recovery route, but the copy and ownership lifecycle are not atomic. Cancellation separately preserves existing availability by skipping the scanner's disappearance sweep.

Hardening Proposals

  • proposed — Establish managed-folder ownership through a serialized reservation or transaction shared with folder creation and removal, then revalidate that identity before scanning. This would preserve one owner across concurrent imports without holding a database transaction throughout file copying.
  • proposed — Create temporary files exclusively without following links, and define whether destination parents may be symlinks. If confinement is required against directory tampering, enforce it using filesystem handles rather than lexical checks alone.

… reported play failures

The drop's task is announced before the walk and its flag stops it; unreadable entries count as errors; a lyrics sidecar is copied under the name its audio lands at; overlap and indexing_folder move to core's scanner::folders. Playing without importing reports a failed picker or command through the playback alert.

Canonicaliser les chemins dans relation

relation compare des composants textuels et ignore les liens symboliques. Un appel peut donc enregistrer /music/Library puis /music/Alias/Albums lorsque Alias pointe vers Library.

WalkDir::new(root).follow_links(false) n’empêche pas la résolution d’un lien utilisé comme composant parent du chemin racine. Les deux scans peuvent lire les mêmes fichiers. Le second scan réattribue alors leur folder_id, et la suppression d’un dossier peut marquer indisponibles les pistes encore associées à l’autre.

Canonicalisez les chemins existants dans cette frontière de comparaison commune. Conservez les chemins originaux pour la base et les messages d’erreur. Ajustez aussi le calcul de profondeur de indexing_folder.

Choosing a free target name and the rename that completes the copy now run under one process-wide lock, recovered if poisoned, so concurrent drops take turns file by file instead of writing the same .waveflow-part.

@coderabbitai About the outside-diff comment on scanner::folders (canonicalising existing paths before relation): declining it, on purpose.

  • The comparison is lexical by design, on the paths the library stores. A track's file_path lies under its folder as given, never as resolved, so this is the form two folders actually conflict in.
  • fs::canonicalize touches the file system for every folder of the profile. On a network share that is offline it can block for seconds, inside the async add_folder_to_library command.
  • It changes the path's form: \\?\ on Windows, a UNC path for a mapped network drive. One side canonicalised and the other missing (the managed folder before its first drop, a folder unplugged) would no longer compare at all, which is worse than the gap it closes.

The gap is real but narrow: an overlap reached only through a junction or a symlink is not seen. The module doc says links are not followed, so it is a stated limit, not a silent one.

@InstaZDLL Merci pour la précision. Je retire ma suggestion de canonicalisation.

La documentation de scanner::folders confirme que la comparaison lexicale est intentionnelle et que les liens ne sont pas suivis. L’implémentation de relation respecte ce contrat, sans accès au système de fichiers.

La canonicalisation ajouterait des accès potentiellement bloquants et risquerait de comparer des formes de chemins incompatibles. Les chevauchements accessibles uniquement par jonction ou lien symbolique restent une limite explicite, pas un défaut à corriger dans cette PR.

Learning: Dans WaveFlow, le module Rust src-tauri/crates/core/src/scanner/folders.rs compare intentionnellement les chemins de manière lexicale, dans leur forme stockée par la bibliothèque. Ne pas proposer de canonicaliser les chemins avant relation : cela ajoute des accès au système de fichiers potentiellement bloquants sur les partages hors ligne et peut produire des formes incompatibles avec les chemins stockés, notamment avec le préfixe Windows \\?\ ou des chemins UNC. Les chevauchements accessibles uniquement par jonction ou lien symbolique constituent une limite explicite du module, dont la documentation indique que les liens ne sont pas suivis.

Learning: Dans WaveFlow, le refus des chevauchements dans `src-tauri/crates/app/src/commands/library.rs`, fonction Rust `add_folder_to_library`, est un choix produit explicite. Il s’applique aussi à l’ajout de `Music` lorsque le dossier géré `Music/WaveFlow` est déjà enregistré. Ne pas proposer une fusion automatique avec réaffectation de `track.folder_id` : cela modifierait implicitement les pistes supprimées lors du retrait d’un dossier. Le parcours prévu affiche un toast qui nomme le dossier bloquant et suggère d’ajouter les autres sous-dossiers.
