feat: upload .lrc, .txt and .ttml lyrics to a track - #300
Merged

Conversation
Step 4 of RFC-012 (decision 6). Uploaded sheets live in their own table,
track_lyrics_upload, beside the scanner's track_lyrics, which every scan
rebuilds; nothing is written next to the audio.
- PUT /api/v2/tracks/{id}/lyrics/{format} stores lrc, txt or ttml, at most
a mebibyte (the route's own body ceiling; the router's default is
16 KiB), decoded through waveflow_core::text_encoding, replacing an
earlier upload in the same format. A sheet with nothing usable in it is
refused with 422. Owners and managers only; a listener gets the 404 an
unseen track would.
- DELETE removes an upload; the track falls back to what was scanned.
- GET /api/v2/tracks/{id}/lyrics now lists every sheet, uploads included,
in one order — uploaded TTML, uploaded LRC, scanned synced, uploaded
TXT, scanned plain — empty ones left out, each naming its source. The
Subsonic methods keep reading the scanned sheets, without a source: their
contract is frozen.
- GET /api/v2/tracks/{id}/lyrics/file downloads the first sheet, or one
upload by ?format=, as application/octet-stream, an attachment, and
nosniff, so an uploaded TTML is never rendered in this origin.
- TTML is read with roxmltree, whose default options refuse a DTD: lines
from each <p> with a begin in clock or offset time, frames refused,
xml:lang as the language. Word timings stay in the stored original.
- The web client's Properties shows each sheet with its source, the one
shown first, and lets owners and managers upload and remove a sheet;
anyone downloads the shown one under the server's name.

The write checked membership and role but not availability, while every read asks for it: a sheet stored for a missing track answered 404 yet went in. The test counts the row, since the 404 alone came from the read after the write. Signed-off-by: InstaZDLL <github.105mh@8shield.net>
A <p> nested in a <p> made every enclosing paragraph copy the inner text again, quadratic in a document the 1 MiB cap does not bound. Only the outermost paragraphs are kept, found without walking into one. Signed-off-by: InstaZDLL <github.105mh@8shield.net>

Explanation
La description est complète. Elle couvre le contexte RFC-012, les changements serveur et client, les règles d’accès, les limites, l’ordre de sélection, les tests, la validation et les points de revue. Elle n’utilise pas exactement les intitulés du modèle et ne contient pas la confirmation explicite du DCO, mais ces omissions ne bloquent pas l’évaluation.

- Around line 170-175: Dans le traitement du texte des paragraphes TTML,
modifiez la collecte utilisée par reads_a_ttml_sheet_with_word_spans pour
insérer un séparateur lorsqu’un élément br est rencontré, tout en conservant les
nœuds texte existants et le nettoyage par espaces. Ajoutez un cas de test
couvrant un paragraphe contenant <br/> afin de vérifier que les mots restent
séparés.
- Around line 144-151: Limitez la recherche de la langue aux nœuds racine et

valeur et le repli vers UNKNOWN_LANG, en utilisant l’itération sur root et les

Step 4 of RFC-012: lyrics uploaded to a track, the one order every reader chooses by, and the lyrics download. Decision 6.
Server
track_lyrics_upload(new dated migration): one sheet per track and format (lrc,txt,ttml), kept beside the scanner'strack_lyrics. Nothing writes a file; the audio stays read-only.PUT /api/v2/tracks/{id}/lyrics/{format}: the body is the file's bytes, decoded throughwaveflow_core::text_encoding(so GB18030 or Shift_JIS sheets read as written). Owners and managers only, like a metadata correction; a listener gets the same 404 as a stranger. A sheet with nothing usable in it answers 422, so an empty upload never stands in front of a real one. The route carries its own body limit of 1 MiB, the sidecar's cap, so anything larger answers 413; everything else keeps the router's 16 KiB.DELETE …/lyrics/{format}: 204, then 404 when there is nothing left to remove.GET …/lyrics/file[?format=]: the sheet shown, or one upload by name, as an attachment (application/octet-stream, RFC 6266filename+filename*,nosniff). An upload comes back as it was uploaded; a scanned sheet is written as.lrcor.txt.One order, decided once in

The local CodeRabbit pass suggested moving the TTML/LRC parsing into
waveflow-core. That is a cross-repository change outside this step. The parser here is small, tested, and only reads uploads; it can move later if the desktop app needs it.Summary by CodeRabbit
