144 Commits • 59 Features
Dec 1, 2024December 2024 (signal18/replication-manager) delivered security, reliability, and onboarding improvements at scale. Key features delivered include: GitLab login support with ACL-based shared clusters view; Admin-only global settings access; peer API handling with token persistence; automated log directory creation for error_log and slow_log; onboarding enhancements including peer registration UI, registration email, and success text notification. Additional improvements included CORS hardening (setting Access-Control-Allow-Origin to '*'), logout token removal, and governance-oriented changes such as enforcing verified GitLab emails for peer access. Major bugs fixed include: fixes to ensure consistent peer cluster list display after the patch (peer list bug fixes); race-condition fix when initializing privileges to prevent access-denied for generated keys; graceful error handling for failed read responses; 404 handling for peer requests; and cleanup preventing keys from being stored in git. The month also laid groundwork for better performance and observability (reduced pull frequency; enhanced logging/monitoring; and deployment hygiene). Overall impact: increased security, multi-tenant readiness, improved developer and user experience, and stronger reliability. Technologies/skills demonstrated include OAuth/GitLab integration, ACL/RBAC refactoring, token lifecycle management, CORS configuration, concurrency/race-condition handling, proactive logging/monitoring, and config/service plan management.
