RAGFlowChainR (development version)

  • Wrapped FTS-related tests in tryCatch() + skip() to avoid segmentation faults on Fedora-clang during CRAN checks.
  • Informative skip() messages added for systems without FTS extension support.
  • Ensured all tests pass cleanly on platforms with partial DuckDB extension support.
  • Maintained full feature test coverage in interactive/development environments.
  • No user-facing changes or exported API modifications.

RAGFlowChainR 0.1.1

CRAN release: 2025-04-24

  • Prevented segfaults on CRAN by disabling the experimental vss extension during checks.

  • Fallback to FLOAT[] column type when vss is unavailable, avoiding Fedora-clang binary-extension errors.

  • create_vectorstore() now:

    • Skips vss installation/loading under CRAN but retains support in dev environments.
    • Returns a persistent DuckDB connection (no longer auto-disconnects).

  • insert_vectors():

    • Handles single-column frames safely using drop = FALSE.
    • Dynamically switches between array_value() and list_value() based on schema.

  • build_vector_index():

    • Skips HNSW index creation when VECTOR[] columns are missing (with a warning).

  • RAG chain integration:

  • DESCRIPTION and metadata:

    • Set minimum required version: duckdb (>= 0.10.0) and testthat (>= 3.0.0).
    • Added Config/testthat/edition: 3 for consistent test behavior.
    • Tidied Description field by removing unnecessary single quotes around names.
    • Expanded common acronyms like HNSW, LLM, etc.

  • Testing improvements:

    • Suppressed non-critical test warnings.
    • Removed fragile FTS assertions (fts_main).
    • Introduced mock_embed() and dummy_embed() to remove dependency on external APIs.
    • Skipped RAG-chain integration tests on CRAN and gated test-data downloads.
