31 Commits • 8 Features
Oct 1, 2025Monthly summary for 2025-10 focused on delivering API rendering and docs improvements, performance optimizations, governance and admin UX enhancements, and testing alignment for kobotoolbox/kpi. Highlights include open API enhancements, HTML rendering for API endpoints, improved docs structure and HTML templates, and Swagger UI fixes. Performance optimizations reduce transaction overhead for submissions, storage counters, and imports. Strengthened permissions and governance with inactive-user handling, non-cascading removal of permissions, and a guard against self-deletion when data exists. Admin UI improvements for data collectors and exposure of collection client URLs in Django Admin, plus OpenAPI schema settings enhancements and updated tests for query counts.

Oct 1, 2024October 2024 focused on security hardening, reliability improvements, and maintainability in kobotoolbox/kpi. Key outcomes include improved SSRF protection parsing, a new multiline parsing utility, and lint/name cleanup for base settings to enhance readability and reduce future bugs. Implemented robust signal management for bulk operations by temporarily disconnecting Celery Beat signals via a context manager, improving reliability and efficiency of bulk updates. Removed throttling around PeriodicTasks.update_changed(), ensuring updates run consistently during change cycles. These changes reduce security risk, increase operational reliability, and improve code quality, enabling faster, safer deployments.
