Lyrics, versioning, and the song page's fact line.
- Lyrics are suggested at submission and never imposed: the worker makes one
LRCLIB lookup, and Hae sanoitukset re-queries with whatever title and artist
are typed. Neither overwrites what the submitter wrote. They live on the
submission, travel to the song at publish, and stay editable after the song
locks — the lock freezes what a song claims to be, and nobody reviewed the
lyrics
- The review strip reads and writes side by side: lyrics left, review right.
Synced LRC highlights the playing line and seeks on click; plain text scrolls
continuously with a nudge knob. Following can be turned off
- CalVer YYYY.MM.DD-N, injected from the git tag with -ldflags, shown in the
footer, the startup log and /healthz
- The song page's metadata became four labelled cells instead of one flat run
of five different kinds of fact
Fixes: publishing wiped lyrics the worker had just fetched (a request that
omitted a field cleared it), lyric auto-scroll landed in the wrong place, and
the fader shifted the deck sideways at score 100.
Step 6. The surfaces around the review loop.
- Nine leaderboards, ordered and limited in SQL, each with a deterministic
tie-break so a tied board doesn't reshuffle between reloads. Min 3 reviews
to qualify, for reviewer boards too
- Profiles show counts and history-wide averages and the member's songs,
never a list of their reviews — per-song opinion stays gated
- Avatars: 5MB in, 256px JPEG out, ffmpeg's re-encode being the validation.
No upload still means initials, and avatars are public
- Changing your own password requires the current one and drops your other
sessions
- Palaute: free text plus the page you were on, carried in a footer link, and
the user agent from the header. Reporters see their own; the admin resolves
them with a timestamp rather than a status enum
- Admin gained the song list with delete, the reports page, and an open-report
count on the dashboard
Two theme fixes the screenshots caught: leaderboard ranks need a CSS counter
because display:grid suppresses list markers, and count-based boards were
printing 3.0 where they mean 3.
Step 5. A URL goes through the same pipeline as an upload — it just gains a
download step and a source_url.
- The host allowlist is checked on the parsed hostname before yt-dlp is
invoked, so lookalikes and userinfo tricks are refused too
- yt-dlp -J reads metadata synchronously with a 15s timeout; a timeout leaves
the fields blank rather than failing the submission
- Over-long tracks are refused from that metadata, before a byte is downloaded
- Failed URL submissions offer Yritä uudelleen with the typed text intact;
uploads cannot retry, so they offer re-upload
Prefill takes track then title, and artist then creator then uploader, and
leaves a field blank rather than inventing one. testdata/ytdlp-noose.json is a
real dump of an ordinary upload, which has none of the music fields.
Also fixes a URL-only submit being blocked by the file input's required
attribute — HTML cannot express "one of these two", so the server says it.
The image now takes yt-dlp from Alpine 3.24 instead of pip, which drops
python3 and pip entirely; see decision 19.
Steps 3 and 4 of the build order. A member can now upload a song, watch it
convert, publish it, and review what everyone else has published.
Pipeline:
- ffprobe reads tags synchronously at submit so prefill never races typing;
ffmpeg converts to Opus in the background, two at a time
- ffmpeg succeeding is the validation — no container sniffing
- publish moves the file inside the transaction, so a song row and its .ogg
appear together or neither does
- five submissions per rolling 24h, failures excluded
Reviews and the reveal rule:
- the queue is unreviewed songs only, oldest first, never your own
- other people's reviews and the average are withheld in the query, not the
template — a hidden average is never sent
- 30 minutes to edit or delete your own review, enforced in the WHERE clause
- deleting the last review unlocks the song for its submitter again
The waiting page has one button: the metadata form autosaves after a pause in
typing, and Julkaise submits it and publishes in the same request, so nothing
is lost without JS.
Genres store an English code and render a Finnish label.
