refactor: break up the three large modules in src/ - #137
Merged
Conversation
`services.rs` held 4 273 lines and a single `impl DomainServices` of some 3 600. The block is now fourteen `impl DomainServices` blocks under `src/services/`, which Rust allows within one crate, and `mod.rs` keeps what they share: the SQL projection macros, the read-model types, `ServiceError`, the struct, and the free row-mapping helpers. Pure movement. The macros stay at the top of `mod.rs`, ahead of the `mod` declarations, so the textual scope of `macro_rules!` reaches every child and none of the 36 call sites changed. The free helpers stay private to `mod.rs`, which its descendants can still see. The one visibility change: nine `*_on` helpers that run inside a caller's transaction are used across the new boundaries, so they widen from private to `pub(super)` — visible within `services` and nowhere else. No behaviour change; 42 unit and 46 integration tests pass unchanged. Signed-off-by: InstaZDLL <github.105mh@8shield.net>
`subsonic.rs` held 2 434 lines flat. It becomes eleven modules under `src/subsonic/` — authentication, browsing, lyrics, playlists, user data, media, shares, administration, node projection, protocol rendering and the error constructors — while `mod.rs` keeps what the dispatch needs: the constants, `Principal`, `Params`, `Node`, `ProtocolError`, the router and `dispatch` itself. Pure movement. Every moved item was private to the flat module, so each widens to `pub(super)` and `mod.rs` re-globs them; no call site changed. Beyond that prefix the only diff is rustfmt wrapping the signatures it pushed past 100 columns. The wire contract is frozen for v2.0-beta and nothing here touches it: 42 unit and 46 integration tests pass unchanged, the Subsonic XML/JSON compatibility test among them. Signed-off-by: InstaZDLL <github.105mh@8shield.net>
`http.rs` held 2 415 lines and every `/api/v2` route. It becomes eighteen modules under `src/api/`, one per resource, plus the three that cut across them: `error` for `ApiError` and its mappings, `access` for who is calling and what their token allows, and `web_session` for the browser's cookies, CSRF and origin checks. `mod.rs` keeps the header constants and `router`. The module is renamed `http` to `api` because that is the surface it serves; `crate::http` was only ever the file it lived in. `mod.rs` re-exports each child, so the hundred-odd `api::` paths the utoipa declaration in `lib.rs` names still resolve, and no handler moved out of reach. The `access` re-export is `pub(crate)`, its widest item being `pub(crate)` too — a `pub use` there re-exports nothing and warns. Pure movement. Private helpers widen to `pub(super)`; the rest is rustfmt wrapping the signatures that prefix pushed past 100 columns. 42 unit and 46 integration tests pass unchanged. Signed-off-by: InstaZDLL <github.105mh@8shield.net>
`services.rs`, `subsonic.rs` and `http.rs` are directories, so the two rules that named them by file pointed at nothing. Adds the layout rule alongside them: which directory carries which surface, what each `mod.rs` is allowed to keep, and why the SQL macros sit ahead of the `mod` declarations. Signed-off-by: InstaZDLL <github.105mh@8shield.net>

Inline comments:
In `@src/api/access.rs`:
- Around line 88-95: Update bearer_token so the Authorization scheme check
accepts “Bearer” with any casing, while preserving the existing token extraction
and non-empty validation behavior.
- Around line 43-53: Update Access::granted_by so non-empty scope lists require
the documented catalog:read scope for Self::Read, while preserving the existing
empty-list behavior and intended Write/Admin implications. Add focused tests
covering an empty list, catalog:read, write, and an unknown scope.
In `@src/api/auth.rs`:
- Around line 92-102: Mettre à jour les annotations OpenAPI de web_login et
web_refresh pour déclarer également les réponses 422 et 503 avec ErrorResponse,
en conservant les statuts existants et leur comportement d’exécution.
In `@src/api/catalog.rs`:
- Line 156: Update the OpenAPI parameter list in the search endpoint’s
#[utoipa::path] attribute to declare the SearchQuery pagination parameters
artist_offset, album_offset, and song_offset, alongside the existing q, offset,
and limit parameters. Preserve their optional i64 query-parameter types so
generated clients can paginate each result type independently.
In `@src/api/error.rs`:
- Around line 110-139: Déplacez le test
secure_cookie_detection_uses_the_parsed_url_scheme dans le module
web_session.rs, près de public_url_is_https, et déplacez
lagged_sync_socket_recovers_from_the_durable_cursor dans sync.rs, près de
sync_notice_action et SyncNoticeAction. Retirez ces tests et leurs imports
associés du module de tests de error.rs, sans modifier leur comportement.
In `@src/api/libraries.rs`:
- Around line 87-102: Update create_library’s scanner.trigger failure handling
so a persisted library is not left without a successful client response: either
return the created library with HTTP 201 and an absent scan_id when queueing
fails, or delete the newly created library before returning
ApiError::Unavailable. Preserve the existing error logging and avoid allowing
retries to create duplicates.
- Around line 120-136: Dans la validation utilisant account_by_id et
all_libraries, remplacez le chargement global par une recherche ciblée de la
bibliothèque via son identifiant. Traitez l’absence de la bibliothèque ou du
compte associé comme une erreur 404, tout en conservant une réponse identique
lorsqu’une bibliothèque appartient à un autre compte.
In `@src/api/web_session.rs`:
- Around line 62-70: Mettre à jour secure_cookies et son flux d’appel afin que
public_url reste prioritaire, mais qu’une URL publique absente ou non HTTPS
utilise le schéma HTTPS transmis par le proxy ou l’option de configuration
explicite prévue. Faire remonter cette information jusqu’à secure_cookies et
conserver Secure activé lorsque le déploiement est TLS derrière un terminateur.
In `@src/services/catalog.rs`:
- Around line 149-152: Replace the local folder_ids serialization in the
surrounding method with the existing super::folder_filter helper, reusing its
returned value directly and preserving the current empty-filter behavior. Remove
the redundant local folder_filter construction while leaving the downstream
filter usage unchanged.
In `@src/services/favorites.rs`:
- Around line 214-227: Move the rating range validation in the relevant
favorites operation before acquiring writer_guard(), beginning the transaction,
or calling claim_operation(). Preserve the existing Invalid error for values
outside 0 through 5 and keep the replay handling unchanged for valid ratings.
In `@src/services/mod.rs`:
- Around line 753-771: Déplacez le bloc de documentation décrivant song_select!,

Ajoutez un test couvrant une ligne track conservée avec is_available à 0 et
vérifiez ce comportement via les données de file concernées.
In `@src/services/playlists.rs`:

la taille de track_ids dans create_playlist_with_context et de la collection
résultant de l’ajout add dans update_playlist_with_context avant toute écriture
en base. Utilisez le même comportement de rejet et le même type d’erreur que
MAX_QUEUE_TRACKS et MAX_SHARE_TRACKS.
- Around line 18-39: Replace the per-playlist song lookup in playlist loading
with one batch flow: collect all track IDs for the account in a single query,
call songs_by_ids_lenient_on once, and group the resolved songs by playlist_id
before constructing PlaylistItem values in the playlists service. In playback.rs
lines 105-125, likewise collect all now_playing track_id values, resolve them
once through songs_by_ids_lenient_on on the shared connection, and associate
results by ID while preserving omission of non-visible tracks.
In `@src/services/shares.rs`:
- Around line 191-216: Update public_share to resolve songs through the lenient
songs_by_ids_lenient_on variant, matching shares_on, so unavailable tracks are
omitted while the share remains accessible after the visit count is recorded.
Preserve the existing visit validation and ShareItem construction.
In `@src/services/songs.rs`:
- Around line 229-244: Dans la méthode starred, acquérir une seule connexion au
début et réutiliser cette connexion pour les trois fetch_all ainsi que pour
attach_album_relations et attach_song_relations, au lieu d’appeler
pool().acquire() séparément pour chaque relation. Préserver l’ordre des requêtes
et leur comportement existant.
In `@src/subsonic/admin.rs`:
- Line 105: Remplacez le panic du sous-dispatch admin dans
src/subsonic/admin.rs:105, au sein du dispatch correspondant, par l’erreur
ProtocolError « Requested method is not implemented ». Appliquez le même
changement dans src/subsonic/shares.rs:66 pour le sous-dispatch des partages,
afin que les méthodes non reconnues renvoient une erreur de protocole plutôt que
de paniquer.
In `@src/subsonic/browse.rs`:
- Around line 401-413: Ajouter la pagination SQL au flux de recherche autour de
catalog_search et de l’appel depuis browse.rs : transmettre les trois BrowsePage
au service, puis appliquer leurs limites et offsets dans la requête avec
LIMIT/OFFSET, en reprenant le modèle de browse_all. Adapter search_result pour
ne plus effectuer une pagination mémoire redondante tout en conservant les
résultats paginés attendus.
In `@src/subsonic/lyrics.rs`:
- Around line 12-23: In the lyrics handler, validate the artist and title
parameters before calling lyrics_by_metadata: when both are absent, return the
empty lyrics Node immediately, preserving any available metadata attributes and
avoiding an unfiltered service lookup. Keep the existing lyrics lookup behavior
when either criterion is present.
In `@src/subsonic/protocol.rs`:
- Around line 312-319: Update xml_escape to remove XML 1.0–forbidden control
characters (U+0000–U+0008, U+000B, U+000C, and U+000E–U+001F) before applying
the existing entity escaping, while preserving all valid characters and current
escaping behavior.

- Around line 54-83: Bound client-provided UUID mutation lists to prevent
unbounded serialized writes. In src/subsonic/userdata.rs lines 54-83, enforce

before the scrobble loop. Use the existing save_queue batching/validation
pattern where applicable, while preserving normal behavior within the limit.

The splitter recognised functions, types and `impl` blocks as top-level items, but not `mod`. The `#[cfg(test)] mod tests` at the end of `http.rs` was therefore swallowed by the range of the item above it and landed in `error.rs`, which covers neither of the two tests it holds. They move to the modules that own what they exercise: `public_url_is_https` to `web_session`, `sync_notice_action` to `sync`. Content unchanged; only the `use super::` line narrows to each module's own items. This is the failure the split cannot verify by compiling — the movement proof compares content, and content was preserved. Filing is what a person has to check. Signed-off-by: InstaZDLL <github.105mh@8shield.net>
Three OpenAPI declarations described less than their handler does. `web_login` reaches 422 through `AuthError::InvalidDeviceName` and 503 through `AuthError::Unavailable`; `web_refresh` and `web_logout` reach 503 the same way, and through `append_cookie`. Their native counterparts declare those statuses already — only the browser variants were short. `/api/v2/search` accepts `artist_offset`, `album_offset` and `song_offset` on `SearchQuery`, which is what lets a client page songs past the end of the artists, but the parameter list named only `q`, `offset` and `limit`, so no generated client could reach them. And in `services/mod.rs`, the doc block describing the batched `track_artist` and `track_genre` reads sat above `folder_filter`, whose own doc followed it without a blank line — so rustdoc merged the two onto the JSON library filter. It goes back onto `attach_song_relations`, which is what it describes. Pre-existing, not from the split. No runtime behaviour changes. Signed-off-by: InstaZDLL <github.105mh@8shield.net>
All pre-existing, none introduced by the split. Kept in their own commit so the movement commits stay verifiable as movement. **A share died with its last track.** `public_share` resolved songs strictly while the owner's listing resolved them leniently, so a track gone unavailable turned every visit into a 404 — after the visit counter had already been incremented, outside the transaction. It now matches `shares_on`. The test proves it: without the change the assertion fails with `NotFound`. **A queue named a song it did not hand back.** `current` was read from the row whatever the lenient resolution returned, so it could point at a track absent from `songs`. It is now cleared when the track is not there. **`Bearer` was matched case-sensitively.** RFC 7235 §2.1 makes the scheme name case-insensitive; a client spelling it `bearer` was turned away as unauthenticated. **XML 1.0 forbids some control characters outright** — U+0000..U+0008, U+000B, U+000C, U+000E..U+001F — and no entity spells them, so a tag carrying one produced a document no client can parse. They are dropped before escaping; tab, newline and carriage return are legal and stay. **`getLyrics` with neither artist nor title** left the lookup unfiltered and answered with whichever track sorts first among those that carry lyrics. Nothing asked for, nothing returned. **An out-of-range rating** was refused only after taking the process-wide writer gate and claiming the operation. The range check moves ahead of both; the claim was rolled back either way, so only the ordering changes. **`starred` acquired five pool connections** for three projections and two relation batches, all answering one question. One connection now serves the whole call. Two assertions added to the existing unavailable-track test, both confirmed to fail against the previous behaviour.

The test asserted `Send(0)` for a user drawn at random, which has no journal entries — so `latest_user_cursor` answers 0, and a branch returning a constant 0 would have passed just as well. It proved the Lagged arm was wired to something, not that it recovers the durable cursor its name claims. It now creates an account and writes one event through the real journal path, then asserts the recovered value equals the cursor that write returned. The empty case stays as a second assertion, since falling back to the base cursor rather than failing is also part of the contract. Checked by replacing the arm with `Send(0)`: the test now fails with left `Send(0)`, right `Send(1)`. Signed-off-by: InstaZDLL <github.105mh@8shield.net>

`main` is at `d36e929` with 48 integration tests. The mission list said the module split and the track pid were still to do; both shipped, as #137 and #139, and each carries the thing the review caught that the first attempt had wrong — a test filed under a module that covers neither, and a hint compared across two specs that are not separate namespaces. Adds the trap that cost `main` six hours of red: a green pull request merged onto a base dependabot had already broken. Check the base commit's CI colour, not only the pull request's. Everything above the mission list is the record of 2026-08-23 and is left as written. Signed-off-by: InstaZDLL <github.105mh@8shield.net>
