Fix: Test-Commit für VCS-Integration (MP-8) (#15)
* MP-8 OTHER Implementiere JWT-Authentifizierungs-Filter im Gateway

* Fix(ci): Update upload-artifact action to v4

* Fix(ci): Add start command for Keycloak and failure logs

* Fix(ci): Remove invalid 'command' property from Keycloak service

* Fix(ci): Use KC_DEV_MODE env var to start Keycloak

* Fix(ci): Keycloak service was removed from GitHub Actions services and replaced with a manual docker run step that starts Keycloak with the start-dev command.

* dev(ci): vereinheitliche Keycloak auf 26.4.2; aktiviere Health im CI (MP-8)

* Fix(ci): Stabilize Keycloak startup in integration tests via matrix

- Add `dev-file` Keycloak variant to matrix for stability fallback.
- Improve wait logic and health checks for Keycloak and Postgres.
- Unify Keycloak version to 26.4.2 across codebase.
- Add log dumps on failure.

* Fix(ci): Die betroffene Datei docs/Visionen-Ideen/Infrastruktur-Strategie_DSGVO-Konformität.md endet aktuell mit genau einer leeren Zeile (Zeile 87). Das entspricht der Regel MD047 („Files should end with a single newline character“). Damit ist deine Korrektur korrekt.

* Fix(ci): Repository-wide auto-fix for Markdown files was implemented with a GitHub Actions workflow and a local helper script. EditorConfig and markdownlint ignore files were added to ensure consistent formatting. Instructions for using the auto-fix both via GitHub Actions and locally were provided.

* fix(gradle): build.gradle.kts jsBrowser testTask disabled

* fix(gradle): build.gradle.kts jsBrowser testTask disabled

* Fix(ci): Stabilize integration tests with Keycloak matrix build (MP-8)

Introduces a matrix strategy (`keycloak_db: [postgres, dev-file]`)
in the integration-tests workflow to mitigate flaky Keycloak starts
when using the Postgres service container.

- Adds a `dev-file` Keycloak variant for stability fallback.
- Improves wait logic and health checks for Keycloak/Postgres.
- Unifies Keycloak version to 26.4.2 across codebase (Dockerfile, Compose,
  ADR, README, tests).
- Adds log dumps on failure in CI.
- Ensures `KC_HEALTH_ENABLED=true` is set.
- Updates related documentation (README, Schlachtplan).
- Includes broader Docker SSoT cleanup (versions.toml as source,
  script updates, env file cleanup, validator hardening).

This resolves recurring CI failures related to Keycloak startup and
ensures required checks for PRs (#15) are reliable, while also
improving overall Docker build consistency.

* feat(docs, ci): Implement YouTrack SSoT strategy with Dokka sync (MP-8)

- Add Dokka multi-module Gradle configuration and KDoc style guide.
- Add GitHub Actions workflow (docs-kdoc-sync.yml) and Python script
  (youtrack-sync-kb.py) to sync Dokka GFM output to YouTrack KB.
- Extend front-matter schema (bc, doc_type) and update relevant pages/stubs.
- Adapt CI scripts (validate-frontmatter, check-docs-drift, ci-docs link ignore).
- Update README.md to reference YouTrack KB.

* Fix(ci): Replace OpenAPI validator with Spectral

Replaces the deprecated 'char0n/swagger-editor-validate' action,
which failed due to sandbox issues in GitHub Actions, with the
modern '@stoplight/spectral-cli'.

This ensures robust OpenAPI specification validation without
requiring a headless browser environment. The 'generate-api-docs'
job now depends on the successful completion of the Spectral validation.

Part of resolving CI failures for PR #15 (MP-8).

* Fix(ci): Specify spectral:oas ruleset for OpenAPI validation (MP-8)

* Fix(ci): Remove explicit ruleset argument for Spectral validation (MP-8)

* Fix(ci): Added a .spectral.yaml file to fix Spectral linting errors. Corrected markdown lint issues in two documentation files. Updated README.md with a new guidelines section to fix link validation errors.

* Fix(ci): Markdownlint errors were fixed by adding required blank lines. The Guidelines Validation error was resolved by updating the README.md link. The API Documentation Generator workflow was stabilized by updating paths, tasks, and validation steps.

* Fix(ci): Alle vier fehlerhaften GitHub-Action-Prüfungen wurden behoben. Fehler in der OpenAPI-Spezifikation, Probleme mit der Markdown-Linting-Analyse und Validierungsfehler bei Querverweisen wurden korrigiert. Die README.md enthält nun alle erforderlichen Links zu den Richtlinien.

* Fix(ci): Markdown linting errors in docs/api/README.md were fixed by specifying languages in fenced code blocks. OpenAPI specification errors in documentation.yaml were resolved by correcting example property types to strings. Cross-reference validation errors in README.md were fixed by adding the missing link to project-standards/coding-standards.md.

* Fix(ci): Duplicate heading errors in docs/api/members-api.md were fixed. Cross-reference validation errors for docker-architecture.md were resolved. All originally reported issues passed validation successfully.

* Fix(ci): The markdown heading levels in docs/api/members-api.md were corrected from h5 to h4 to fix linting errors. The missing cross-reference link from technology-guides/docker/docker-development.md to docker-overview.md was added. These fixes resolved the original validation and linting errors causing the process to fail.

* Fix(ci): Duplicate heading warnings in docs/api/members-api.md were resolved. Cross-reference validation for docker-development.md to docker-architecture.md was fixed. A new unrelated warning about docker-production.md was identified but not addressed.

* refactor(ci,docs): Simplify CI pipeline and migrate docs to YouTrack SSoT

BREAKING CHANGE: Documentation structure radically simplified

- Consolidate 9 GitHub Actions workflows into 1 main pipeline (ci-main.yml)
- Remove redundant workflows: ci-docs, markdownlint-autofix, guidelines-validation, api-docs
- Delete documentation migrated to YouTrack: api/, BCs/, Visionen-Ideen/, reference/, now/, overview/
- Keep only ADRs, C4 diagrams, and essential dev guides in repo
- Update README.md with YouTrack KB links
- Create new docs/README.md as documentation gateway
- Relax markdown-lint config for pragmatic developer experience

Kept workflows:
- ssot-guard.yml (Docker SSoT validation)
- docs-kdoc-sync.yml (KDoc → YouTrack sync)
- integration-tests.yml (Integration tests)
- deploy-proxmox.yml (Deployment)
- youtrack-sync.yml (YouTrack integration)

* refactor(ci,docs): Die Markdownlint-Fehler in README.md und docs/README.md wurden behoben, indem die Überschriftenebenen angepasst, überflüssige Satzzeichen am Ende entfernt und die notwendigen Leerzeilen um Überschriften, Listen, Tabellen und Codeblöcke eingefügt wurden. Das problematische Leerzeichen am Ende in docs/README.md wurde ebenfalls entfernt. Die Dateien entsprechen nun den vorgegebenen Markdownlint-Regeln und sollten die CI-Validierung bestehen.

Redis Cache Module

Überblick

Dieses Modul stellt eine konkrete Implementierung der cache-api unter Verwendung von Redis als Caching-Backend bereit.

Architektur

Das Modul folgt dem Provider-Pattern:

  • cache-api: Provider-agnostische Interfaces (CacheService, DistributedCache)
  • redis-cache: Redis-spezifische Implementierung

Verwendung

Dependency Hinzufügen

dependencies {
    implementation(projects.infrastructure.cache.redisCache)
}

Konfiguration

Das Modul verwendet Spring Boot Auto-Configuration. Konfigurieren Sie Redis über application.yml:

redis:
  host: localhost
  port: 6379
  password: null  # Optional
  database: 0     # Default cache database
  connectionTimeout: 2000
  readTimeout: 2000
  usePooling: true
  maxPoolSize: 8
  minPoolSize: 2

Code-Beispiel

@Service
class MyService(private val cache: DistributedCache) {

    suspend fun getData(key: String): MyData? {
        return cache.get(key, MyData::class)
    }

    suspend fun saveData(key: String, data: MyData) {
        cache.put(key, data, ttl = 1.hours)
    }
}

Features

  • TTL-Unterstützung für Cache-Einträge
  • Connection State Tracking
  • Health Monitoring
  • Jackson-basierte Serialisierung
  • Connection Pooling mit Lettuce
  • Kotlin Coroutines Support

Beans

Das Modul registriert folgende Spring Beans:

  • redisConnectionFactory: Standard Redis ConnectionFactory
  • redisTemplate: RedisTemplate<String, ByteArray> für Cache-Operationen
  • cacheSerializer: Jackson-basierter Serializer (kann überschrieben werden)
  • cacheConfiguration: Standard Cache-Konfiguration (kann überschrieben werden)

Gleichzeitige Verwendung mit redis-event-store

⚠️ WICHTIG: Wenn Sie sowohl redis-cache als auch redis-event-store im selben Service verwenden:

Unterschiedliche Databases

Die Module verwenden separate Redis Databases, um Konflikte zu vermeiden:

  • redis-cache: Database 0 (Standard)
  • redis-event-store: Database 1 (konfigurierbar)

Konfigurationsbeispiel

# Redis Cache Konfiguration
redis:
  host: localhost
  port: 6379
  database: 0  # Cache verwendet Database 0
# Redis Event Store Konfiguration
redis:
  event-store:
    host: localhost
    port: 6379
    database: 1  # Event Store verwendet Database 1

Bean-Namen

Die Module verwenden unterschiedliche Bean-Namen:

Komponente redis-cache redis-event-store
ConnectionFactory redisConnectionFactory eventStoreRedisConnectionFactory
Template redisTemplate eventStoreRedisTemplate
Serializer cacheSerializer eventSerializer

Keine Konflikte

Die Module sind so designed, dass sie ohne Konflikte gleichzeitig verwendet werden können:

  • Separate ConnectionFactories mit @Qualifier
  • Separate Property-Prefixes (redis vs redis.event-store)
  • Unterschiedliche Database-Nummern
  • Unterschiedliche Bean-Namen

Serialisierung

Das Modul verwendet Jackson für die Serialisierung:

  • Automatische Kotlin-Modul Integration
  • Java 8 Date/Time Support
  • Custom Serializer können via @Bean überschrieben werden

Health Checks

Das Modul tracked automatisch den Redis-Verbindungsstatus:

  • Connection State (CONNECTED, DISCONNECTED, CONNECTING)
  • Connection State Listeners für Benachrichtigungen
  • Automatische Reconnect-Versuche

Performance

  • Connection Pooling: Wiederverwendbare Verbindungen via Lettuce
  • Non-blocking I/O: Reaktive Operations mit Kotlin Coroutines
  • Optimierte Serialisierung: Jackson-basiert mit Byte-Array-Caching

Troubleshooting

Redis Verbindungsfehler

RedisConnectionFailureException: Unable to connect to Redis

Lösung: Überprüfen Sie Redis-Server und Netzwerk-Konfiguration.

Serialisierungsfehler

SerializationException: Could not serialize object

Lösung: Stellen Sie sicher, dass Ihre Datenklassen mit Jackson serialisierbar sind (data classes, keine private Konstruktoren).

Bean-Konflikte mit Event Store

Wenn Sie Fehler wie "Multiple beans of type RedisConnectionFactory" erhalten:

Lösung: Verwenden Sie @Qualifier Annotations oder stellen Sie sicher, dass Sie die neueste Version beider Module verwenden (Bean-Namen-Konflikte sind bereits behoben).
