Jul 1, 2026July 2026 monthly summary for CorfuDB/CorfuDB: Executed a security-focused dependency maintenance patch with a Netty upgrade to 4.2.15.Final to remediate a set of CVEs (including request smuggling, DNS codec validation, memory exhaustion, and related issues). No source code changes were required; this was a pure dependency management task. The change reduces security risk across the distributed storage stack and aligns with security advisories. Verified compatibility via existing tests and CI, with no behavior changes observed. Key audit trail documented in the commit ee401a0aa71979eb6d30c607164174c672d31e9a, including CVE references. This effort strengthens the platform’s security posture and demonstrates disciplined maintenance practices that enable faster risk response while preserving stability.

Mar 1, 2026March 2026 monthly summary for CorfuDB/CorfuDB focusing on Java version upgrade and CI/CD alignment. Key outcomes include migrating the core codebase from JDK 21 to JDK 25, updating CI/CD pipelines to reference the new Java version, and aligning Docker/Maven configurations with the new runtime. The effort also encompassed stabilizing cloud deployment tests and ensuring branch hygiene after merge. Summary of work: - Upgraded CorfuDB from JDK 21 to JDK 25 and aligned CI/CD pipelines to use Java 25 across workflows, including updates to 8 workflows and documentation. Commits include a full migration (Migrate CorfuDB to JDK 25) and branch synchronization after the merge. - Modernized Docker and Maven configurations for JDK 25 compatibility, upgrading base images to eclipse-temurin:25-jdk-noble and adding necessary --add-opens flags to handle Java module encapsulation; Maven source/target updated to 25 and related flags added in tests and plugins. - Stabilized Docker API interactions and environment: pinned Docker API version to 1.43 across install steps, added DOCKER_API_VERSION where needed, and updated cloud deployment tests to remove deprecated flags. - Improved cloud deployment test reliability: pre-created /tmp/k3dvol to prevent k3d warnings and updated k3s arguments from --no-deploy to --disable, ensuring smoother test runs. - Branch and documentation hygiene: switched corfudb-cloud branch to master after JDK25 merge and updated README with new JDK requirement. No API breakages identified. Business impact: The upgrade enables the project to run on a modern, supported Java runtime with improved security and performance, while maintaining compatibility and stability in CI/CD, deployment pipelines, and tests. The changes reduce upgrade risk and improve developer productivity through more reliable, reproducible builds.
