Improves messaging when an existing upgrade lock file is present, adds warnings in non-development environments, and enhances path handling and module loading for robustness. Impact: clearer upgrade workflows and fewer operational surprises. Major bugs fixed: - WebDAV Permissions Refinement for Update vs Delete (commit 7895f0039754bf2ab0b0e4bc2ef4d2efc570bb0a, Issue 51500). Fix incorrect access control logic for WebDAV by aligning permissions with DeletePermission, ensuring users who can update but not delete are treated correctly. Impact: correct access behavior and reduced privilege misconfigurations. - Database Connection Shutdown Cleanup (commit 6558f096d9f84bc22335b25f371a14547d2dd611, Issue 51483). Ensure long-running database connections are forcibly closed during server shutdown to prevent resource leaks; refine shutdown listener behavior across modules. Impact: reduced resource leaks and improved shutdown reliability. Overall impact and accomplishments: - Strengthened reliability: more predictable upgrade flows and robust shutdown handling reduce downtime risk and support smoother maintenance windows. - Improved security posture: hiding server details by default and improving access control logic reduces exposure vectors and aligns with compliance requirements. - Operational efficiency: clearer upgrade lock messaging and robust module loading simplify issue diagnostics and onboarding of new deployments. Technologies/skills demonstrated: - Java server lifecycle management (shutdown handling, listener behavior) - Access control and WebDAV permission modeling - Upgrade/lock file workflows and robust path/module loading - Site customization testing and test-driven development
