fix: stop button e hang su ffmpeg orfano in Upgrade (bump v1.9.2)

Il worker Python era bloccato in `for line in proc.stdout` che non ritornava mai quando il subprocess yt-dlp veniva killed ma lasciava figli ffmpeg orfani con pipe stdout ancora aperto. Effetti: 1) Il bottone Stop non fermava l'upgrade 2) Anche il watchdog kill non liberava il thread Fix: - Lettura stdout in thread separato + queue.Queue - Main loop polla ogni 500ms con timeout: controlla is_stopped() e proc.poll() -> Stop risponde entro 1s - Watchdog usa kill() (SIGKILL) invece di terminate() (SIGTERM) per garantire cleanup child orfani
fix: watchdog su download upgrader (bump v1.9.1)

+# Traxsource Charts — Design Spec
+
+- **Data:** 2026-08-01
+- **Autore:** LuZa + Claude
+- **Stato:** Approvato, pronto per implementation plan
+- **Target release:** MusicTools v1.9.0
+
+## Obiettivo
+
+Nuova tab "▲ Traxsource" nell'app che permette di:
+
+1. Scegliere un genere musicale da un elenco di ~15 generi Traxsource
+2. Caricare la **Top 100** ufficiale del mese corrente per quel genere
+3. Anteprima checkbox + download riusando il pipeline esistente (Spotify search → yt-dlp → tag ID3 + cover)
+
+Sostituisce l'attività manuale di copiare/incollare tracklist Traxsource.
+
+## Non-goals
+
+- Chart diverse dalla Top 100 (Must Have, Just Added, ecc.)
+- Ricerca artista/label specifica su Traxsource
+- Preview audio (Traxsource ha DRM)
+- Duration tracks (non è nell'HTML della lista; sarebbe una richiesta extra per track)
+- Login/account Traxsource
+
+## Ricognizione tecnica (fatta 2026-08-01)
+
+- **Cloudflare Managed Challenge attivo** su tutte le pagine tranne home e /top. Bypass: session-based con `curl_cffi.Session(impersonate='chrome131')`, prima GET a `/`, poi le pagine sensibili con `Referer: https://www.traxsource.com/`.
+- **Non è Next.js** → no `__NEXT_DATA__`. HTML server-rendered.
+- **Struttura URL:**
+  - Genre index: `/genre/<id>/<slug>` — es. `/genre/18/tech-house`. Contiene solo 10 top track più altri widget
+  - Top 100 corrente: `/title/<title_id>/top-100-<genre>-of-<month>-<year>` — es. `/title/2847986/top-100-tech-house-of-july-2026`. Contiene 100 track completi in un unico documento (~394KB)
+  - **Il title_id cambia ogni mese.** Non è hardcodabile. Va scoperto dinamicamente
+- **Discovery Top 100 URL:** nella pagina `/genre/<id>/<slug>` c'è (almeno un) `<a href="/title/<id>/top-100-<slug>-of-<month>-<year>">`. Estrai col regex `href="(/title/\d+/top-100-[a-z0-9-]+)"`
+- **Track markup (stabile):**
+  ```html
+  <div data-trid="14842066" class="top-item play-trk ptk-14842066">
+    <div class="ttib position">1</div>
+    <div class="image"><img src="https://.../52x52/HASH.jpg" /></div>
+    <div class="ttib info">
+      <a href="/track/14842066/badman-sound-extended-mix" class="com-title">Badman Sound (Extended Mix)</a>
+      <a href="/artist/92248/hannah-wants" class="com-artists">Hannah Wants</a>,
+      <a href="/artist/321517/trace" class="com-artists">Trace</a>
+      <a href="/label/325/nervous" class="com-label">Nervous</a>
+    </div>
+  </div>
+  ```
+  Class names sono stabili (semantici, non generati da bundler).
+- **Cover art:** URL contiene la size (`/52x52/`). Sostituendo con `/500x500/` si ottiene la versione grande per tagging ID3.
+
+## Approccio scelto
+
+- Session `curl_cffi` con `impersonate='chrome131'`. Cookie CF conservati automaticamente. Preriscaldamento con GET a `/` al primo utilizzo.
+- Parser: `BeautifulSoup4` con selettori CSS puliti — `div.top-item.play-trk` per righe, `a.com-title` per titolo, `a.com-artists` per artisti, `a.com-label` per label, `div.ttib.position` per rank, `img` per cover URL.
+- Regex sul titolo per estrarre "mix name" tra parentesi: `Song Title (Extended Mix)` → title="Song Title", mix="Extended Mix".
+- Cache in-memory 15 min per la lista, come Beatport.
+- Genere → (numeric_id, slug, display_name) map hardcoded (estratti dalla home /top).
+
+**Alternative scartate:**
+- `requests` puro: bloccato da CF, verificato
+- API interna Traxsource: non esistono API pubbliche gratuite documentate; reverse engineering rischio ban
+- Playwright: overkill (~100MB dep) quando session + BeautifulSoup basta
+

+        TraxsourceParseError su HTML non conforme (title link non trovato, meno di 50 track, ecc.)
+    """
+```
+
+**Internals:**
+- `_session()` singleton — inizializza `curl_cffi.Session(impersonate='chrome131')` e fa GET a `/` una volta per riscaldare CF cookies. Riusata per tutte le fetch successive.
+- `_discover_top100_url(session, slug) → str` — fetcha `/genre/<id>/<slug>`, regex per il link Top 100
+- `_parse_tracks(html) → list[TraxsourceTrack]` — BeautifulSoup, itera `div.top-item.play-trk`, estrae campi
+- `_split_title_mix(full_title) → (title, mix)` — parsa `"Foo (Extended Mix)"` → `("Foo", "Extended Mix")`. Se no parentesi, mix = "".
+- `_format_artists(anchors) → str` — join `[a.text for a in anchors]` con formattazione "A, B & C"
+- `_large_cover(url) → str` — sostituisce `/52x52/` con `/500x500/` nel path
+
+**Retry + timeout:** riusa gli stessi pattern di `core/beatport.py`: 3 tentativi con backoff [1, 3]s, timeout 15s.
+
+### Nuovi metodi in `api/bridge.py`
+
+Paralleli ai metodi Beatport (stesso schema):
+
+- `traxsource_genres() → list[dict]`
+- `traxsource_fetch_chart(slug, force_refresh) → {ok, tracks} | {ok:false, error, message}` — salva anche `traxsource_last_genre` in config
+- `traxsource_check_existing(tracks, genre_name) → list[bool]` — check in `<output_dir>/Traxsource_<genre>/`
+- `traxsource_download_selected(tracks, genre_name) → dict` — costruisce metadata (title/artist/album=label/date=YYYY-MM/genre=display_name/cover_url) e chiama `start_tracks_download` riusando il pipeline con tagging ID3
+
+**Metadata per il tagger:**
+- title, artist: dai campi track
+- album: label Traxsource (best proxy — non c'è "album" per singole tracce)
+- date: mese/anno corrente (dato che la Top 100 è mensile)
+- genre: display_name del genere
+- cover_url: `cover_url_large` (500x500)
+
+### Frontend
+
+Nuova tab in sidebar dopo YouTube (o Beatport):
+```html
+<button class="nav-item" data-view="traxsource" data-feature="audio">
+  <span class="nav-icon">▲</span><span>Traxsource</span>
+</button>
+```
+
+Section `#view-traxsource` con struttura identica a Beatport (dropdown genere + Carica Top 100 + tabella + toolbar + log). Riusa tutte le classi `.beatport-*` per lo stile.
+
+Modulo `TraxsourceUI` in `webui/js/app.js` — copia diretta di `BeatportUI` con selettori cambiati (`traxsource-*` invece di `beatport-*`) e chiamate API alle nuove funzioni.
+
+**Ordinamento colonne** (sortable) e **cover art** già supportati riusando la stessa struttura tabella + modulo helper `_sortPairs`/`_bindSortableHeaders`/`_updateSortArrows` esistenti.
+
+### Persistenza
+
+Nuovo campo in `core/config.py::DEFAULTS`:
+```python
+"traxsource_last_genre": "tech-house",
+```
+
+### Dipendenze
+
+- `beautifulsoup4` — nuova dep runtime. Aggiungere in `requirements.txt`. Serve `--collect-data bs4` in build_windows.py + build_macos.py? Verificare — bs4 di solito no.
+
+## Testing
+
+**Unit tests `tests/test_traxsource.py` (senza rete, con fixture HTML):**
+
+Serve una fixture HTML reale della pagina Top 100 (~400KB). Task 1 la genera con `curl_cffi` come fatto per Beatport (`beatport_melodic_top100.html`).
+
+| Test | Verifica |
+|---|---|
+| `test_list_genres_shape` | Lista dict con {slug, id, name}, ordinati |
+| `test_parse_top100_extracts_100_tracks` | Fixture HTML → 100 track |
+| `test_parse_positions_sequential` | 1..100 senza buchi |
+| `test_parse_track_shape` | Ogni track ha title, artists, label, cover URLs non vuoti |
+| `test_split_title_mix_with_parens` | `"Foo (Extended Mix)"` → `("Foo", "Extended Mix")` |
+| `test_split_title_mix_no_parens` | `"Foo"` → `("Foo", "")` |
+| `test_format_artists_multi` | `["A", "B", "C"]` → `"A, B & C"` |
+| `test_large_cover_url_substitution` | `.../52x52/x.jpg` → `.../500x500/x.jpg` |
+| `test_discover_top100_url_returns_playlist_link` | HTML genre stub → estrae `/title/N/top-100-...` |
+| `test_fetch_top100_invalid_slug_raises_value_error` | slug non in GENRES → ValueError early |
+
+Mock HTTP con `unittest.mock.patch("core.traxsource._session")` (patch della session singleton).
+
+**Test manuale end-to-end:**
+1. Avvia app → tab Traxsource
+2. Selezione "Tech House" → Carica Top 100 → tabella 100 righe in <5s
+3. Verifica cover art (thumbnail nella tabella)
+4. Deseleziona 90, tieni 10 → Scarica selezionati
+5. File in `MUSICA/Traxsource_Tech House/` con tag ID3 completi (title, artist, album=label, genre=Tech House, cover 500x500)
+6. Ricarica stesso genere → cache hit
+7. Riavvio → ultimo genere ricordato
+
+## Rollout
+
+1. Branch `feat/traxsource-charts`
+2. Bump `core/config.py::VERSION` → `v1.9.0` (minor: nuova tab visibile)
+3. Note release `/tmp/notes-v1.9.0.md`
+4. Merge → tag → CI → server DB update (stesso flusso di sempre)
+
+## Struttura file impattati
+
+**Nuovi:**
+- `core/traxsource.py` (~250 LOC)
+- `tests/test_traxsource.py` (~200 LOC)
+- `tests/fixtures/traxsource_tech_house_top100.html` (~400KB)
+- `scripts/refresh_traxsource_genres.py` (~50 LOC, opzionale)
+
+**Modificati:**
+- `requirements.txt` — `beautifulsoup4>=4.12.0`
+- `build_windows.py` + `build_macos.py` — verificare se serve `--collect-data bs4`
+- `core/config.py` — VERSION bump + `traxsource_last_genre`
+- `api/bridge.py` — 4 metodi Api `traxsource_*` (~150 LOC)
+- `webui/index.html` — nav-item + section (~90 LOC)
+- `webui/js/app.js` — modulo `TraxsourceUI` (~250 LOC, copia BeatportUI adattata)
+
+## Considerazioni operative
+
+- **Fragility scraping:** i class name di Traxsource (`com-title`, `com-artists`, `top-item`, ecc.) sono usati anche nel JS del sito → stabili nel tempo. Rischio: se Traxsource migra a un framework nuovo (React/Next), parser va rifatto.
+- **Rate limiting:** un solo GET per la genre + un GET per la playlist Top 100 = 2 richieste per caricare la chart. Cache 15 min. Zero rischio ban in uso normale.
+- **Legal:** stesso perimetro di Beatport — lettura di pagine pubbliche, no ToS violation esplicito.
+- **Comparabilità con Beatport:** un utente power potrebbe usare entrambe le tab per triangolare le release del mese. UX consistente = curva apprendimento zero.

luciano	eb20a034e6	fix: stop button e hang su ffmpeg orfano in Upgrade (bump v1.9.2) Il worker Python era bloccato in `for line in proc.stdout` che non ritornava mai quando il subprocess yt-dlp veniva killed ma lasciava figli ffmpeg orfani con pipe stdout ancora aperto. Effetti: 1) Il bottone Stop non fermava l'upgrade 2) Anche il watchdog kill non liberava il thread Fix: - Lettura stdout in thread separato + queue.Queue - Main loop polla ogni 500ms con timeout: controlla is_stopped() e proc.poll() -> Stop risponde entro 1s - Watchdog usa kill() (SIGKILL) invece di terminate() (SIGTERM) per garantire cleanup child orfani	2026-08-02 11:37:40 +02:00

Ora: threading.Timer da 5 min uccide il subprocess se in scaduta.
