3 Commits • 2 Features
Oct 1, 2025Month: 2025-10. This month focused on establishing Microsoft 365 OAuth readiness in enso-org/enso and delivering end-to-end OAuth support. Key outcomes include groundwork for OAuth integration (environment and GUI configuration updates, removal of an obsolete sign-out URL, and updated dev-env submodules) and the introduction of end-to-end Microsoft 365 OAuth authentication (CI/workflow changes, environment variable updates, and new MS365 credential types/forms). No major bugs were reported in this period. Overall impact: enables enterprise-grade authentication, improves security posture, and accelerates future SSO integration with Microsoft 365. Technologies demonstrated: DevOps and CI/CD, environment/configuration management, GUI and submodule maintenance, OAuth 2.0 flows, and credential management for MS365.

Jun 1, 2025June 2025: Delivered significant improvements to the fixed-width data ingestion path in enso-org/enso, including robust encoding support (BOM handling, encoding detection, and fallbacks) and automatic column inference, along with row skipping and row limiting. These changes improve reliability when ingesting legacy data sources, broaden encoding compatibility, and reduce ingestion errors in edge cases. Targeted code cleanup removed verbose debug logging from Reporting_Stream_Decoder_Helper.enso to improve maintainability and reduce log noise. Overall, these efforts strengthen data ingestion capabilities, lower maintenance costs, and enhance interoperability for customers relying on legacy fixed-width formats.

Dec 1, 2024December 2024 in enso-org/enso focused on reliability, data freshness, and API capabilities. Delivered cross-component reload detection that clears caches on reload actions and ensures fresh data across the HTTP cache (LRUCache) and Excel connection pool. Improved HTTP cache behavior in low-disk environments with bounded file sizes and better error reporting for oversized responses, supported by tests for streaming fetch. Implemented deterministic sorting for File.list outputs to ensure predictable UI and downstream processing. Expanded Enso Tables with add_group_number to enumerate groups of rows (Unique and Equal_Count modes), with accompanying docs and tests. These changes reduce stale data risk, improve resilience and observability, and enable higher-level data operations across the platform.
