April 2026 (2026-04) monthly summary for containers/ramalama focusing on local path handling, RAG transport reliability, and model versioning semantics. Delivered fixes, validation, and test coverage that improve local usage, avoid unnecessary network pulls, and strengthen versioning guarantees. Key features delivered: - Bug fix: RagTransport local path handling preserved local model strings by introducing an overridable formatting hook (OCI.format_model) and early kind initialization. This prevents local directories from being incorrectly treated as images and stops exists() from falling through to podman pull. Committed changes include: 2ef2b9468ea669372f67fc77dd2318af04b900ba. - Feature: Model Versioning Validation for IMAGE-mode to ensure :latest suffix is applied. Added test asserting IMAGE-mode model gets the :latest suffix. Commit: 8b4d907888a89fa8d9f6cad097a1d858f30c937a. Major bugs fixed: - Corrected RagTransport local path handling to preserve filesystem paths and avoid false errors when checking path existence. This eliminates erroneous pulls and TTY issues reported when local Rag directories are used. Overall impact and accomplishments: - Increased reliability and correctness of local RAG usage and model versioning in IMAGE-mode, reducing runtime errors and network pulls. - Strengthened test coverage for local path handling, DB classification, and IMAGE-mode suffix behavior, enabling safer refactors and faster iteration. Technologies/skills demonstrated: - Python OOP and subclassing (RagTransport, OCI.format_model override) - Test-driven development with pytest and regression tests - Clear commit discipline and documentation in changes (anchored to issue fixes and feature adds)
