Socket Unix / systemd:
- RuntimeDirectory=logcorrelator dans logcorrelator.service : systemd
recrée /run/logcorrelator avec logcorrelator:logcorrelator à chaque
démarrage/restart, éliminant le problème de droits root:root
- Ajout de packaging/rpm/logcorrelator-tmpfiles.conf pour recréer le
répertoire au boot via systemd-tmpfiles (couche de protection boot)
- Retrait de /var/run/logcorrelator du RPM %files et du %post
- Dockerfile.package : copie de logcorrelator-tmpfiles.conf dans SOURCES/
Corrélation — bugs:
- Fix CRITIQUE emitPendingOrphans : corruption de slice lors de l'expiration
simultanée de plusieurs orphelins pour la même clé (aliasing du tableau
sous-jacent, orphelins émis en double et fantômes persistants)
- Fix HAUT rotateOldestA : événement silencieusement perdu même avec
ApacheAlwaysEmit=true ; retourne désormais *CorrelatedLog propagé dans
ProcessEvent
- Fix MOYEN processSourceB (pending orphan path) : en mode one_to_many, le
B event n'était pas bufferisé après corrélation avec un pending orphan A,
cassant le Keep-Alive pour les requêtes A2+ sur la même connexion
- Fix BAS : suppression du champ mort timer *time.Timer dans pendingOrphan
Corrélation — observabilité:
- Ajout keepalive_seq (1-based) dans NormalizedEvent : numéro de requête
dans la connexion Keep-Alive, incrémenté par processSourceA
- Tous les logs orphelins incluent désormais keepalive_seq=N
- keepAliveSeqA nettoyé automatiquement à l'expiration du TTL B
Tests: 4 nouveaux tests de non-régression (32 tests au total)

- feat: new config directive include_dest_ports ([]int) in correlation section
- feat: if non-empty, only events with a matching dst_port are correlated
- feat: filtered events are silently ignored (not correlated, not emitted as orphan)
- feat: new metric failed_dest_port_filtered tracked in ProcessEvent
- feat: DEBUG log 'event excluded by dest port filter: source=A dst_port=22'
- test: TestCorrelationService_IncludeDestPorts_AllowedPort
- test: TestCorrelationService_IncludeDestPorts_FilteredPort
- test: TestCorrelationService_IncludeDestPorts_EmptyAllowsAll
- docs(readme): full rewrite to match current code (v1.1.12)
- docs(readme): add include_dest_ports section, fix version refs, clean outdated sections
- docs(arch): add dest_port_filtering section, failed_dest_port_filtered metric, debug log example
- fix(config.example): remove obsolete stdout.level field
- chore: bump version to 1.1.12

- feat(observability): correlation metrics (events, success/failed, reasons, buffers)
- feat(correlation): IP exclusion filter (exact IPs and CIDR ranges)
- feat(correlation): pending orphan delay for late-arriving B events
- fix(stdout): sink is now a no-op for data; JSON must never appear on stdout
- fix(clickhouse): all flush errors were silently discarded, now properly logged
- fix(clickhouse): buffer overflow with DropOnOverflow now logged at WARN
- fix(clickhouse): retry attempts logged at WARN with attempt/delay/error context
- feat(clickhouse): connection success logged at INFO, batch sends at DEBUG
- feat(clickhouse): SetLogger() for external logger injection
- test(stdout): assert stdout remains empty for correlated and orphan logs
- chore(rpm): bump version to 1.1.11, update changelog
- docs: README and architecture.yml updated

Build optimizations implemented:
1. Makefile: Remove --no-cache flag
- Docker builds now use layer cache (incremental builds)
- Added DOCKER_BUILDKIT=1 for better performance
- Added buildx support for parallel builds
- New targets: docker-build-dev-no-test, package-rpm-sequential
2. Dockerfile: Add SKIP_TESTS argument
- SKIP_TESTS=true for faster production builds
- Tests still run in CI by default
- Added BuildKit cache mounts for:
- /go/pkg/mod (Go modules)
- /var/cache/apt (APT cache)
- /var/lib/apt/lists (APT lists)
3. Dockerfile.package: Factorize common RPM tools
- New stage: rpm-common-tools (shared across el8/el9/el10)
- fpm installed once, reused 3 times
- Common build script: /build-rpm.sh
- Reduced duplication from 300 lines to 60 lines per stage
4. Parallel RPM builds with buildx
- make package-rpm now uses buildx for parallel builds
- el8, el9, el10 built simultaneously
- Fallback: make package-rpm-sequential (if buildx fails)
Expected performance gains:
- Incremental build (code change only): 15-25 min → 3-5 min (-80%)
- Full build (no cache): 15-25 min → 8-12 min (-50%)
- RPM builds (parallel): 9 min → 4 min (-55%)
- Total typical workflow: ~20 min → ~5-7 min (-65%)

- Fix cleanExpired() to use TTL map instead of event timestamp for B events
- Increase default correlation time window from 1s to 10s
- Increase default network TTL from 30s to 120s for long sessions
- Use payload timestamp for network events when available (fallback to now)
- Add comprehensive Keep-Alive tests (TTL reset, long session scenarios)
- Bump version to 1.1.7

- Install logcorrelator.yml.example to /etc/logcorrelator/ instead of /usr/share/logcorrelator/
- Change default socket permissions from 0660 to 0666 (world read/write)
- Bump version to 1.1.2
- Remove CHANGELOG.md

- Replace rocky8/rocky9/almalinux10 with el8/el9/el10
- Rename Docker build stages: rpm-rocky* → rpm-el*
- Update Makefile to use new directory structure
- Update comments: 'Rocky Linux' → 'Enterprise Linux'
- Simplify Docker volume mount path for RPM output
This makes the naming more generic and aligned with RPM conventions
(el8, el9, el10) rather than specific distribution names.
