feat: v6.4.0 Realtime production — merge 3-voix (au-delà du LWW) + broadcast non bloquant
- app/services/realtime_merge.py : merge à 3 voix diff3-lite, regions disjointes conservees, conflit par champ + drapeau - protocole base (client embarque la base de sa saisie) ; sans base -> LWW historique (retro-compat) - ack renvoie le bloc fusionne + conflict ; adoption cote client + toast ; broadcast du resultat fusionne - broadcast non bloquant : file sortante + tache writer par connexion, coalescence des curseurs - clients trop lents deconnectes (4413), budget ops anti-flood (400/10s) - fix fuite room 4404 + room_state() sur page inexistante - GET /api/realtime/stats (observabilite) - 26 tests test_realtime_v64.py ; suite 725 verte ; ruff + eslint OK ; version 6.4.0

# Changelog - FlowDeck
|
||||
|
||||
## v6.4.0 (2026-09-22) — Realtime editing (production)
|
||||
|
||||
> Le realtime passe en mode production : résolution de conflits au-delà du last-write-wins (merge à trois versions) et édition à grande échelle (broadcast non bloquant, coalescence des curseurs, corrections de fuites, observabilité).
|
||||
|
||||
### Added
|
||||
|
||||
- **Merge à 3-voix (diff3-lite)** — nouveau `app/services/realtime_merge.py` :
|
||||
- `merge_text_3way(base, current, incoming)` : fusion de caractères. Les régions modifiées qui ne se chevauchent pas sont **toutes conservées** (les deux saisies survivent) ; ordre d'arrivée indifférent ; un chevauchement réel retombe en LWW et est signalé.
|
||||
- `merge_block_3way(base, current, incoming)` : fusion **champ-par-champ**. Serveur et client modifiant des champs différents n'ont plus de conflit ; conflit limité au seul champ divergent (plus « tout le bloc perdu »).
|
||||
- Fonctions pures, testées sans WebSocket ni base de données.
|
||||
- **Protocole `base`** — chaque `update` envoyé par le client embarque la version du bloc dont dérive sa saisie ; le serveur calcule `merge_block_3way(base, current, incoming)`. Sans `base` (ancien client) → LWW historique, rétro-compatible.
|
||||
- **Adoption du résultat fusionné** — l'`ack` renvoie le bloc fusionné + drapeau `conflict` ; le client met à jour sa `base`, adopte le résultat (hors bloc en cours d'édition) et affiche un toast en cas de conflit. Le serveur diffuse toujours le bloc final fusionné pour convergence de tous les pairs.
|
||||
- **Broadcast non bloquant** — chaque connexion a une file sortante (`asyncio.Queue`) + une tâche `_writer` dédiée ; `_broadcast()` fait `put_nowait` et n'attend plus le socket → un client lent ne fige plus la room entière.
|
||||
- **Coalescence des curseurs** — le writer réduit les messages `sel` empilés à la position la plus récente (seule la dernière compte), en préservant l'ordre des messages importants.
|
||||
- **Anti-flood** — budget d'opérations par connexion (`OP_WINDOW_MAX=400` / fenêtre 10 s) ; au-delà, réponse `ack stale` sans application.
|
||||
- **Observabilité** — `GET /api/realtime/stats` (authentifié) : rooms, connexions (dont totales), ops, merges, conflits, déconnexions lentes, + détail par page.
|
||||
|
||||
### Changed
|
||||
|
||||
- **Déconnexion des clients trop lents** — file sortante pleine (`MAX_OUT_QUEUE=512`) → fermeture 4413 + compteur `slow_disconnects`, pour qu'une room ne stagne jamais sur un pair mortel.
|
||||
- `app/templates/_page_editor_realtime.html` — les updates incluent désormais `base` ; nouveau traitement de l'`ack` avec `merged`.
|
||||
|
||||
### Fixed
|
||||
|
||||
- **Fuite de rooms** — une tentative de connexion WS sur une page inexistante (4404) enregistrait une `Room` orpheline en mémoire pour toujours ; la room n'est plus enregistrée tant que la page n'est pas validée.
|
||||
- **`room_state()` sur page inexistante** — retournait/plantait sur `None` ; retourne désormais `{"blocks": [], "title": "", "version": 0}` sans laisser d'entrée dans `_rooms`.
|
||||
|
||||
### Tests
|
||||
|
||||
- **26 nouveaux tests** `tests/test_realtime_v64.py` : merge purs (régions disjointes, ordre indépendant, chevauchement → conflit, suppression de champ, id préservé), protocole WS (ack fusionné, convergence de 2 clients sur le même bloc, rétro-compat LWW sans `base`, conflit scalaire), fuite 4404, coalescence des curseurs, endpoint stats, anti-flood.
|
||||
- **14 tests** `tests/test_realtime.py` existants préservés (non-régression).
|
||||
- `ruff check app tests` OK · `eslint static/js` 0 problème.

#### Conflits au-delà du LWW
|
||||
|
||||
- [x] **Merge à 3 voix (diff3-lite)** — nouveau service `app/services/realtime_merge.py` : `merge_text_3way()` (merge de caractères) + `merge_block_3way()` (merge champ-par-champ), fonctions pures et testées sans WebSocket ni base
|
||||
- [x] **Régions disjointes conservées** — deux utilisateurs tapant à des endroits différents du *même* bloc voient leurs deux saisies survivre (au lieu d'écraser l'une par l'autre) ; ordre d'arrivée indifférent
|
||||
- [x] **Chevauchement réel → LWW par champ + drapeau** — un conflit n'est plus « tout le bloc perdu » mais limité au champ concerné ; `conflict: true` renvoyé dans l'`ack` et le broadcast
|
||||
- [x] **Protocole `base`** — le client embarque dans chaque `update` la version du bloc dont dérive sa saisie ; le serveur fait `merge_block_3way(base, current, incoming)` ; sans `base` → LWW historique (rétro-compat ancien client)
|
||||
- [x] **Adoption côté client** — l'`ack` renvoie le bloc fusionné ; le client met à jour sa `base`, adopte le résultat (hors bloc en cours d'édition) et affiche un toast en cas de conflit
|
||||
- [x] **Broadcast du résultat fusionné** — le serveur diffuse toujours le bloc final fusionné (jamais la proposition brute) pour convergence garantie de tous les clients
|
||||
|
||||
#### Échelle & robustesse
|
||||
|
||||
- [x] **Broadcast non bloquant** — chaque connexion a une file sortante (`asyncio.Queue`) + une tâche `_writer` dédiée ; `_broadcast()` fait `put_nowait` et n'attend plus le socket → un client lent ne fige plus la room
|
||||

|
||||
- [x] **Anti-flood** — budget d'opérations par connexion (`OP_WINDOW_MAX=400` / 10 s) ; au-delà, réponse `ack stale` sans application
|
||||
- [x] **Fix fuite de rooms** — une connexion 4404 n'enregistre plus de `Room` orpheline en mémoire ; `room_state()` sur page inexistante retourne un dict vide au lieu de planter sur `None`

merge à trois versions des opérations de blocs (au-delà du last-write-wins) +

|
||||
|
||||
Améliorations « production » par rapport à v5.13.0 :
|
||||
|
||||
* **Conflits** — les mises à jour de bloc embarquent la ``base`` dont dérive la
|
||||
saisie du client ; le serveur fait un merge 3-voix champ-par-champ + texte
|
||||
(voir ``realtime_merge``) au lieu d'écraser le bloc entier. Les deux saisies
|
||||
disjointes survivent, les chevauchements réels retombent en LWW *par champ*
|
||||
avec drapeau de conflit renvoyé au client.
|
||||
* **Échelle** — chaque connexion possède une file sortante + une tâche writer
|
||||
dédiée ; le broadcast devient non bloquant (un client lent ne bloque plus la
|
||||
room), les mises à jour de curseur se coalescent (une seule par flush), et un
|
||||
client trop lent (file pleine) est déconnecté proprement (4413).
|
||||
* **Anti-flood** — budget d'opérations par connexion (fenêtre glissante).
|
||||
* **Fuites corrigées** — une room 4404 n'est plus enregistrée ; ``room_state``
|
||||
ne crée plus d'objet None ; les rooms vides sont évacuées.
|
||||
* **Observabilité** — compteurs (rooms, conns, ops, merges, conflits, déconnexions
|
||||
lentes) exposés par ``stats()``.
|
||||
|
||||
Rooms in-memory (un seul worker uvicorn). Persistance en base (page.content)
|
||||
avec debounce. Fallback polling côté client si le WS est indisponible.
