feat: Add integration tests 8-10 & fix CTest configuration
Added three new integration test scenarios: - Test 08: Config Hot-Reload (dynamic configuration updates) - Test 09: Module Dependencies (dependency injection & cascade reload) - Test 10: Multi-Version Coexistence (canary deployment & progressive migration) Fixes: - Fixed CTest working directory for all tests (add WORKING_DIRECTORY) - Fixed module paths to use relative paths (./ prefix) - Fixed IModule.h comments for clarity New test modules: - ConfigurableModule (for config reload testing) - BaseModule, DependentModule, IndependentModule (for dependency testing) - GameLogicModuleV1/V2/V3 (for multi-version testing) Test coverage now includes 10 comprehensive integration scenarios covering hot-reload, chaos testing, stress testing, race conditions, memory leaks, error recovery, limits, config reload, dependencies, and multi-versioning. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>

# Scénario 8: Config Hot-Reload
|
||||
|
||||
**Priorité**: ⭐ NICE TO HAVE
|
||||
**Phase**: 3 (NICE TO HAVE)
|
||||
**Durée estimée**: ~1 minute
|
||||
**Effort implémentation**: ~3-4 heures
|
||||
|
||||
---
|
||||
|
||||
## 🎯 Objectif
|
||||
|
||||
Valider que le système peut modifier la configuration d'un module à la volée sans redémarrage, avec:
|
||||
- Changement de paramètres en temps réel
|
||||
- Reconfiguration sans perte de state
|
||||
- Support de multiples types de configuration (scalaires, listes, objets)
|
||||
- Validation des valeurs et rollback en cas d'erreur
|
||||
|
||||
---
|
||||
|
||||
## 📋 Description
|
||||
|
||||
### Setup Initial
|
||||
1. Charger `ConfigurableModule` avec configuration de base:
|
||||
- `spawnRate`: 10 entités/seconde
|
||||
- `maxEntities`: 50
|
||||
- `entitySpeed`: 5.0
|
||||
- `colors`: ["red", "blue"]
|
||||
- `physics.gravity`: 9.8
|
||||
- `physics.friction`: 0.5
|
||||
2. Spawner des entités pendant 10 secondes
|
||||
3. Vérifier que les entités respectent la config initiale
|
||||
|
||||
### Phase 1: Config Hot-Reload Simple
|
||||
1. À t=10s, modifier configuration:
|
||||
- `spawnRate`: 20 (doubler le taux de spawn)
|
||||
- `entitySpeed`: 10.0 (doubler la vitesse)
|
||||
2. Appliquer config via `updateConfig()` sans reload du module
|
||||
3. Vérifier que:
|
||||
- Nouvelles entités utilisent nouvelle config
|
||||
- Entités existantes **gardent** leur config d'origine (continuité)
|
||||
- Pas de perte de state
|
||||
|
||||
### Phase 2: Config Hot-Reload Complexe
|
||||
1. À t=20s, modifier configuration avancée:
|
||||
- `maxEntities`: 100 (augmenter limite)
|
||||
- `colors`: ["green", "yellow", "purple"] (nouvelles couleurs)
|
||||
- `physics.gravity`: 1.6 (gravité lunaire)
|
||||
2. Vérifier que:
|
||||
- Nouvelles entités spawnent avec nouvelles couleurs
|
||||
- Physique appliquée correctement
|
||||
- Limite respectée
|
||||
|
||||
### Phase 3: Config Invalide + Rollback
|
||||
1. À t=30s, tenter d'appliquer config invalide:
|
||||
- `spawnRate`: -5 (négatif = invalide)
|
||||
- `maxEntities`: 1000000 (trop grand)
|
||||
2. Vérifier que:
|
||||
- Config invalide rejetée
|
||||
- Config précédente (valide) restaurée
|
||||
- Aucune corruption de state
|
||||
- Erreur loggée clairement
|
||||
|
||||
### Phase 4: Config Partielle
|
||||
1. À t=40s, modifier seulement une partie de la config:
|
||||
- `entitySpeed`: 2.0
|
||||
- (laisser tous les autres paramètres inchangés)
|
||||
2. Vérifier que:
|
||||
- Seul `entitySpeed` est modifié
|
||||
- Autres paramètres préservés
|
||||
- Merge correct

## 📅 Planning
|
||||
|
||||
**Jour 8 (3h):**
|
||||
- Implémenter `updateConfig()` et `updateConfigPartial()` dans IModule
|
||||
- Implémenter ConfigurableModule avec validation
|
||||
|
||||
**Jour 9 (1h):**
|
||||
- Implémenter test_08_config_hotreload.cpp
|
||||
- Debug + validation
|
||||
|
||||
---
|
||||
|
||||
## 🎯 Valeur Ajoutée
|
||||
|
||||
Ce test valide une fonctionnalité **cruciale pour le développement** :
|
||||
- **Tweaking en temps réel** : Ajuster paramètres de gameplay sans redémarrer
|
||||
- **A/B testing** : Tester différentes configs rapidement
|
||||
- **Debug facilité** : Modifier valeurs pour reproduire bugs
|
||||
- **Production-ready** : Hot-config peut servir en prod (feature flags, tuning)
|
||||
|
||||
Contrairement au hot-reload de code (recompilation), le hot-reload de config est **instantané** et ne nécessite pas de rebuild.

# Scénario 9: Module Dependencies
|
||||
|
||||
**Priorité**: ⭐ CRITICAL
|
||||
**Phase**: 2 (CRITICAL)
|
||||
**Durée estimée**: ~2 minutes
|
||||
**Effort implémentation**: ~4-5 heures

|
||||
|
||||
## 🎯 Objectif
|
||||
|
||||
Valider que le système peut gérer des modules avec dépendances explicites, où un module A dépend d'un module B, avec:
|
||||
- Cascade reload automatique (reload de B → force reload de A)
|
||||
- Ordre de reload correct (B avant A)
|
||||
- Protection contre déchargement si dépendance active
|
||||
- Détection de cycles de dépendances
|
||||
- Préservation des données partagées entre modules

## 📋 Description
|
||||
|
||||
### Architecture des Modules de Test
|
||||
|
||||
**BaseModule**: Module de base sans dépendances
|
||||
- Expose des services/données (ex: génère des nombres aléatoires)
|
||||
- Trackable pour valider les reloads
|
||||
- Version incrémentale
|
||||
|
||||
**DependentModule**: Module qui dépend de BaseModule
|
||||
- Déclare explicitement BaseModule comme dépendance
|
||||
- Utilise les services de BaseModule
|
||||
- Doit être rechargé si BaseModule est rechargé
|
||||
|
||||
**IndependentModule**: Module sans dépendances
|
||||
- Sert de témoin (ne devrait jamais être affecté)
|
||||
- Permet de valider que seules les bonnes dépendances sont reload
|
||||
|
||||
### Setup Initial
|
||||
1. Charger **BaseModule** (version 1)
|
||||
- Expose service: `generateNumber()` → retourne 42
|
||||
- Pas de dépendances
|
||||
2. Charger **DependentModule** (version 1)
|
||||
- Dépend de: `["BaseModule"]`
|
||||
- Utilise `BaseModule.generateNumber()`
|
||||
- Accumule les résultats
|
||||
3. Charger **IndependentModule** (version 1)
|
||||
- Pas de dépendances
|
||||
- Témoin indépendant
|
||||
4. Vérifier que tous les modules sont chargés et fonctionnent
|
||||
|
||||
### Phase 1: Cascade Reload (BaseModule → DependentModule)
|
||||
**Durée**: 30 secondes
|
||||
|
||||
1. À t=10s, modifier et reloader **BaseModule** (version 2)
|
||||
- `generateNumber()` → retourne maintenant 100
|
||||
2. Vérifier cascade reload:
|
||||
- ✅ BaseModule rechargé automatiquement
|
||||
- ✅ DependentModule **forcé** à reloader (cascade)
|
||||
- ✅ IndependentModule **non** rechargé (isolé)
|
||||
3. Vérifier ordre de reload:
|
||||
- BaseModule reload **avant** DependentModule
|
||||
- État cohérent (pas de références cassées)
|
||||
4. Vérifier continuité:
|
||||
- State de DependentModule préservé
|
||||
- Nouvelles valeurs de BaseModule utilisées (100 au lieu de 42)
|
||||
|
||||
**Métriques**:
|
||||
- Cascade reload time: temps total pour recharger B + A
|
||||
- Dependency resolution time: temps pour identifier dépendants
|
||||
|
||||
### Phase 2: Protection contre Déchargement
|
||||
**Durée**: 10 secondes
|
||||
|
||||
1. À t=40s, tenter de **décharger BaseModule**
|
||||
2. Vérifier rejet:
|
||||
- ❌ Déchargement **refusé** (DependentModule en dépend)
|
||||
- ⚠️ Erreur claire: "Cannot unload BaseModule: required by DependentModule"
|
||||
- ✅ BaseModule reste chargé et fonctionnel
|
||||
3. Vérifier stabilité:
|
||||
- Tous les modules continuent de fonctionner
|
||||
- Aucune corruption de state
|
||||
|
||||
### Phase 3: Reload Module Dépendant (sans cascade inverse)
|
||||
**Durée**: 20 secondes
|
||||
|
||||
1. À t=50s, modifier et reloader **DependentModule** (version 2)
|
||||
- Change comportement interne
|
||||
- Garde même dépendance sur BaseModule
|
||||
2. Vérifier isolation:
|
||||
- ✅ DependentModule rechargé
|
||||
- ✅ BaseModule **non** rechargé (pas de cascade inverse)
|
||||
- ✅ IndependentModule toujours isolé
|
||||
3. Vérifier connexion:
|
||||
- DependentModule peut toujours utiliser BaseModule
|
||||
- Pas de références cassées
|
||||
|
||||
### Phase 4: Détection de Cycle de Dépendances
|
||||
**Durée**: 20 secondes
|
||||
|
||||
1. À t=70s, créer module **CyclicModule** avec dépendance circulaire:
|
||||
- CyclicModuleA dépend de CyclicModuleB
|
||||
- CyclicModuleB dépend de CyclicModuleA
|
||||
2. Tenter de charger les deux modules
|
||||
3. Vérifier détection:
|
||||
- ❌ Chargement **refusé**
|
||||
- ⚠️ Erreur claire: "Cyclic dependency detected: A → B → A"
|
||||
- ✅ Aucun module partiellement chargé (transactional)
|
||||
4. Vérifier stabilité:
|
||||
- Modules existants non affectés
|
||||
- Système reste stable
|
||||
|
||||
### Phase 5: Déchargement en Cascade
|
||||
**Durée**: 20 secondes
|
||||
|
||||
1. À t=90s, décharger **DependentModule** (libère dépendance)
|
||||
2. Vérifier libération:
|
||||
- ✅ DependentModule déchargé
|
||||
- ✅ BaseModule toujours chargé (encore utilisable)
|
||||
3. À t=100s, décharger **BaseModule** (maintenant possible)
|
||||
4. Vérifier succès:
|
||||
- ✅ BaseModule déchargé (plus de dépendants)
|
||||
- ✅ IndependentModule toujours actif (isolé)

### ModuleLoader Extensions
|
||||
|
||||
Le `ModuleLoader` doit être étendu pour:
|
||||
|
||||
1. **Dependency Resolution**:
|
||||
```cpp
|
||||
// Lors du chargement
|
||||
std::vector<std::string> resolveDependencies(const std::string& moduleName);
|
||||
bool checkCyclicDependencies(const std::string& moduleName, std::set<std::string>& visited);
|
||||
```
|
||||
|
||||
2. **Cascade Reload**:
|
||||
```cpp
|
||||
// Lors du reload
|
||||
std::vector<std::string> findDependents(const std::string& moduleName);
|
||||
void reloadWithDependents(const std::string& moduleName);
|
||||
```
|
||||
|
||||
3. **Unload Protection**:
|
||||
```cpp
|
||||
// Lors du déchargement
|
||||
bool canUnload(const std::string& moduleName, std::string& errorMsg);
|
||||
```
|
||||
|
||||
### Dependency Graph
|
||||
|
||||
```
|
||||
Phase 1-5:
|
||||
┌─────────────────┐
|
||||
│ IndependentModule│ (isolated, never reloaded)
|
||||
└─────────────────┘
|
||||
|
||||
┌──────────────┐
|
||||
│ BaseModule │ (no dependencies)
|
||||
└──────┬───────┘
|
||||
│
|
||||
│ depends on
|
||||
▼
|
||||
┌──────────────────┐
|
||||
│ DependentModule │ (depends on BaseModule)
|
||||
└──────────────────┘
|
||||
|
||||
Cascade reload:
|
||||
BaseModule reload → DependentModule reload (cascade)
|
||||
DependentModule reload → BaseModule NOT reloaded (no reverse cascade)
|
||||
|
||||
Phase 4 (rejected):
|
||||
┌────────────────┐ ┌────────────────┐
|
||||
│ CyclicModuleA │───────▶│ CyclicModuleB │
|
||||
└────────────────┘ └────────┬───────┘
|
||||
▲ │
|
||||
└───────────────────────────┘
|
||||
CYCLE! → REJECTED

|
||||
|

|
||||
|
||||
## 🎯 Valeur Ajoutée
|
||||
|
||||
Ce test valide une fonctionnalité **critique pour les systèmes complexes** :
|
||||
- **Modularité avancée** : Permet de construire des architectures avec dépendances claires
|
||||
- **Sécurité** : Empêche les déchargements dangereux qui casseraient des références
|
||||
- **Maintenabilité** : Cascade reload automatique garantit cohérence
|
||||
- **Robustesse** : Détection de cycles évite les deadlocks et états invalides
|
||||
|
||||
Dans un moteur de jeu réel, typiquement:
|
||||
- **PhysicsModule** dépend de **MathModule**
|
||||
- **RenderModule** dépend de **ResourceModule**
|
||||
- **GameplayModule** dépend de **PhysicsModule** et **AudioModule**
|
||||
|
||||
Le hot-reload de `MathModule` doit automatiquement recharger `PhysicsModule` et tous ses dépendants (`GameplayModule`), dans l'ordre topologique correct.

|
||||
**Priorité**: ⭐⭐ HIGH
|
||||
**Phase**: 3 (ADVANCED)

|
||||
|
||||
## 🎯 Objectif
|
||||
|
||||
Valider que le système peut gérer plusieurs versions d'un même module chargées simultanément en production, avec:
|
||||
- Chargement de multiples versions (v1, v2, v3) du même module en parallèle
|
||||
- Canary deployment (routage progressif du traffic vers nouvelle version)
|
||||
- Migration progressive du state entre versions
|
||||
- Rollback instantané en cas de problème
|
||||
- Isolation mémoire complète entre versions (pas de corruption croisée)
|
||||
- Garbage collection automatique des versions inutilisées

## 📋 Description
|
||||
|
||||
### Cas d'Usage Réel
|
||||
|
||||
Dans un jeu en production, ce scénario permet de:
|
||||
- **Zero-downtime deployments**: Déployer nouveau système de combat sans redémarrer serveurs
|
||||
- **Canary releases**: Tester optimisation sur 10% des joueurs avant rollout complet
|
||||
- **A/B testing**: Comparer performance v1 vs v2 en production avec métriques
|
||||
- **Instant rollback**: Revenir à version stable en < 1s si bugs critiques
|
||||
- **Blue/Green deployment**: Basculer instantanément entre versions
|
||||
|
||||
### Architecture des Modules de Test
|
||||
|
||||
**GameLogicModule v1**: Version baseline
|
||||
- Logic simple: position update (x += vx * dt, y += vy * dt)
|
||||
- 100 entités actives
|
||||
- Pas de collision detection
|
||||
- Version = 1
|
||||
|
||||
**GameLogicModule v2**: Version avec nouvelle feature
|
||||
- Logic v1 + collision detection (nouvelle feature)
|
||||
- Compatibilité state avec v1
|
||||
- Version = 2
|
||||
|
||||
**GameLogicModule v3**: Version optimisée
|
||||
- Physics system optimisé (SIMD, spatial hashing)
|
||||
- Collision detection améliorée
|
||||
- Version = 3
|
||||
|
||||
### Setup Initial (Phase 0)
|
||||
**Durée**: 10 secondes
|
||||
|
||||
1. Charger **GameLogicModule v1**
|
||||
- 100 entités actives (position, velocity)
|
||||
- State baseline enregistré
|
||||
2. Vérifier stabilité:
|
||||
- ✅ v1 traite 100% des entités
|
||||
- ✅ Aucune erreur
|
||||
- ✅ Performance baseline établie
|
||||
|
||||
### Phase 1: Canary Deployment v2
|
||||
**Durée**: 30 secondes
|
||||
|
||||
**Objectif**: Tester v2 sur 10% du traffic (canary)
|
||||
|
||||
1. À t=10s, charger **GameLogicModule v2** en parallèle de v1
|
||||
2. Configurer traffic split:
|
||||
- 90% → v1 (90 entités)
|
||||
- 10% → v2 (10 entités, canary)
|
||||
3. Vérifier isolation:
|
||||
- ✅ v1 traite exactement 90 entités
|
||||
- ✅ v2 traite exactement 10 entités
|
||||
- ✅ Total = 100 entités (aucune perdue)
|
||||
- ✅ State complètement isolé (pas de corruption)
|
||||
- ✅ Canary accuracy: 10% ±2%
|
||||
|
||||
**Métriques**:
|
||||
- `version_load_time_ms`: Temps de chargement de v2 (< 200ms)
|
||||
- `canary_accuracy`: Précision du routage (10% ±2%)
|
||||
- `isolation_check`: Aucune corruption mémoire croisée
|
||||
|
||||
### Phase 2: Progressive Migration v1 → v2
|
||||
**Durée**: 40 secondes
|
||||
|
||||
**Objectif**: Migration graduelle du traffic vers v2
|
||||
|
||||
1. Migration progressive du traffic:
|
||||
- t=50s: **30% v2, 70% v1** (30 entités → v2)
|
||||
- t=60s: **50% v2, 50% v1** (50 entités → v2)
|
||||
- t=70s: **80% v2, 20% v1** (80 entités → v2)
|
||||
- t=80s: **100% v2, 0% v1** (migration complète)
|
||||
|
||||
2. Vérifier migration:
|
||||
- ✅ State migré progressivement (pas de perte)
|
||||
- ✅ Chaque étape: total = 100 entités
|
||||
- ✅ Performance stable durant migration
|
||||
- ✅ Aucune corruption de données
|
||||
|
||||
**Métriques**:
|
||||
- `state_migration_time_ms`: Temps pour migrer state v1→v2 (< 500ms)
|
||||
- `migration_data_loss`: Aucune entité perdue (0)
|
||||
- `traffic_accuracy`: Précision du routage à chaque étape (±2%)
|
||||
|
||||
### Phase 3: Garbage Collection v1
|
||||
**Durée**: 10 secondes
|
||||
|
||||
**Objectif**: Décharger automatiquement v1 (plus utilisée)
|
||||
|
||||
1. À t=90s, déclencher auto GC:
|
||||
- v1 inutilisée depuis 10s (0% traffic)
|
||||
- Seuil GC atteint
|
||||
2. Vérifier déchargement:
|
||||
- ✅ v1 déchargée automatiquement
|
||||
- ✅ v2 continue sans interruption (100 entités)
|
||||
- ✅ Mémoire libérée (> 95% de la mémoire v1)
|
||||
|
||||
**Métriques**:
|
||||
- `gc_trigger_time_s`: Temps avant GC après inutilisation (10s)
|
||||
- `gc_efficiency`: % mémoire libérée (> 95%)
|
||||
- `gc_time_ms`: Temps pour GC complète (< 100ms)
|
||||
|
||||
### Phase 4: Emergency Rollback v2 → v1
|
||||
**Durée**: 20 secondes
|
||||
|
||||
**Objectif**: Rollback instantané si v2 plante
|
||||
|
||||
1. À t=100s, simuler bug critique dans v2:
|
||||
- Exception dans collision detection
|
||||
- Ou: performance dégradée (lag)
|
||||
- Ou: corruption de state
|
||||
2. Déclencher rollback automatique:
|
||||
- Recharger v1 en urgence
|
||||
- Restaurer state depuis backup
|
||||
3. Vérifier rollback:
|
||||
- ✅ v1 rechargée en < 200ms
|
||||
- ✅ State restauré depuis backup (aucune perte)
|
||||
- ✅ Service continuity (downtime < 1s)
|
||||
- ✅ 100 entités actives
|
||||
|
||||
**Métriques**:
|
||||
- `rollback_time_ms`: Temps total de rollback (< 200ms)
|
||||
- `rollback_downtime_ms`: Temps sans service (< 1000ms)
|
||||
- `state_recovery`: State restauré complètement (100%)
|
||||
|
||||
### Phase 5: Three-Way Coexistence (v1, v2, v3)
|
||||
**Durée**: 30 secondes
|
||||
|
||||
**Objectif**: 3 versions en parallèle (A/B/C testing)
|
||||
|
||||
1. À t=120s, charger v3 (version optimisée)
|
||||
2. Configurer traffic split à 3 voies:
|
||||
- 20% → v1 (20 entités, baseline)
|
||||
- 30% → v2 (30 entités, feature test)
|
||||
- 50% → v3 (50 entités, optimized test)
|
||||
3. Vérifier coexistence:
|
||||
- ✅ 3 versions actives simultanément
|
||||
- ✅ Total = 100 entités (aucune perdue)
|
||||
- ✅ Isolation mémoire stricte (3 heaps séparés)
|
||||
- ✅ Routage correct du traffic (±2%)
|
||||
- ✅ Métriques séparées par version
|
||||
|
||||
**Métriques**:
|
||||
- `multi_version_count`: Nombre de versions actives (3)
|
||||
- `traffic_split_accuracy`: Précision du routage 3-voies (±2%)
|
||||
- `memory_isolation`: Aucune corruption croisée (100%)
|
||||

|
||||
|
||||
---
|
||||
|
||||
## ✅ Critères de Succès
|
||||
|
||||
### MUST PASS
|
||||
1. ✅ Chargement de 3 versions du même module simultanément
|
||||
2. ✅ Traffic routing précis (±2% de la cible) pour canary et 3-way split
|
||||
3. ✅ Migration de state progressive sans perte de données
|
||||
4. ✅ Rollback en < 200ms avec state restauré
|
||||
5. ✅ Isolation mémoire complète (aucune corruption croisée)
|
||||
6. ✅ GC automatique des versions inutilisées après seuil
|
||||
7. ✅ Total entités constant (100) durant toutes les phases
|
||||
8. ✅ Aucun crash durant tout le test
|
||||
|
||||
### NICE TO HAVE
|
||||
1. ✅ Hot-patch d'une version sans full reload (micro-update)
|
||||
2. ✅ A/B testing metrics (compare perf v1 vs v2 vs v3)
|
||||
3. ✅ Version pinning (certaines entités forcées sur version spécifique)
|
||||
4. ✅ Circuit breaker (auto-rollback si error rate > 5%)
|
||||
5. ✅ Canary promotion automatique si metrics OK après 30s

- Étendre IModule avec `migrateStateFrom()`
|
||||
- Implémenter GameLogicModuleV1, V2, V3
|
||||
- Créer Entity struct et logic de base
|
||||
|
||||
**Jour 14 (3h):**
|
||||
- Implémenter MultiVersionEngine class
|
||||
- Implémenter TrafficRouter (canary, multi-way split)
|
||||
- Implémenter StateMigrator
|
||||
|
||||
**Jour 15 (2h):**
|
||||
- Implémenter Auto GC system
|
||||
- Implémenter Emergency Rollback
|
||||
- Ajouter métriques par version
|
||||
|
||||
**Jour 16 (2h):**
|
||||
- Implémenter test_10_multiversion_coexistence.cpp
|
||||
- Debug + validation
|
||||
- Intégration CMake

## 🎯 Valeur Ajoutée
|
||||
|
||||
Ce test valide une fonctionnalité **critique pour la production** :
|
||||
|
||||
### Zero-Downtime Deployments
|
||||
- Déployer nouveau système de combat sans arrêter serveurs
|
||||
- Migration progressive pour minimiser risques
|
||||
- Rollback instantané si problème
|
||||
|
||||
### Canary Releases
|
||||
- Tester nouvelle version sur 5-10% des joueurs d'abord
|
||||
- Comparer métriques (perf, bugs) avant rollout complet
|
||||
- Réduire blast radius si bugs critiques
|
||||
|
||||
### A/B Testing en Production
|
||||
- Comparer performance v1 vs v2 vs v3 avec vraies données
|
||||
- Décisions data-driven pour optimisations
|
||||
- Validation de nouvelles features avant déploiement global
|
||||
|
||||
### Business Value
|
||||
- **Réduction des downtimes** : 0s au lieu de 5-10min par déploiement
|
||||
- **Réduction des risques** : Canary détecte bugs avant rollout complet
|
||||
- **Time-to-market** : Déploiements plus fréquents et plus sûrs
|
||||
- **Player experience** : Aucune interruption de service
|
||||
|
||||
### Exemple Réel
|
||||
Dans un MMO avec 100k joueurs connectés:
|
||||
1. Deploy nouveau système PvP sur 5% (5k joueurs)
|
||||
2. Monitor crash rate, lag, feedback
|
||||
3. Si OK → gradual rollout 10% → 30% → 100%
|
||||
4. Si bug critique → instant rollback en < 1s
|
||||
5. Zero downtime, minimal risk

* - Phase 1: Cascade reload (BaseModule → DependentModule)

* with canary deployment, progressive migration, and instant rollback.
|

* - Phase 1: Canary deployment (10% v2, 90% v1)
|

* - Phase 2: Progressive migration (v1 → v2: 30%, 50%, 80%, 100%)
|

* - Phase 3: Auto garbage collection (unload v1)
|
||||
* - Phase 4: Emergency rollback (v2 → v1)
|
||||
* - Phase 5: Three-way coexistence (20% v1, 30% v2, 50% v3)
