Apr 1, 2026April 2026 (cs3org/reva) monthly summary focused on improving ACL robustness in the EOS integration. Delivered a critical bug fix for EOS ACL error handling by introducing explicit checks for error codes in EOS ACL responses. The fix reduces the risk of silent failures, enhances fault tolerance, and improves incident response for ACL management in EOS workflows. This aligns with reliability and security goals for the EOS-backed ACL subsystem and sets the stage for future resilience improvements.

The month focused on centralizing and hardening the sharing subsystem, delivering two core features, and fixing critical reliability issues to improve business impact and stability. Key features delivered: - SQL Share Driver Integration: Migrated the SQL share driver from cernbox/reva-plugins into the core cs3org/reva repository, aligning data models, management, and driver initialization; resolved a registration bug to ensure reliable startup and operation. - Project Admin Shares View Enhancement: Enabled project admins to view all shares within a project, introduced a storage-space cache to optimize performance, fixed an infinite loop in mtime handling, and updated related tests. Major bugs fixed: - OCM Sharing Robustness: Hardened OCM-based sharing by guarding queries behind OCMEnabled, handling OCM errors gracefully, and filtering shares to prevent memory leaks. - Machine-type Authentication Safety: Prevented creation of home directories for users authenticating with the 'machine' type to avoid unnecessary resource provisioning. Overall impact and accomplishments: - Increased stability and reliability of the sharing subsystem, enabling scalable admin governance and safer user provisioning. Centralized core sharing functionality in the main repository to streamline maintenance and iteration, reducing risk of regressions and optimizing performance for admin workflows. Technologies/skills demonstrated: - Go-based backend integration, repository migration, caching strategies, error handling, testing, and performance optimization for share listings.
