Each database owns an embedder, so embedding per database cost a round
trip each. One database still embeds inside the repository, which returns
early for a filter that matches nothing.
haiku.rag.config exported two configuration instances: the lazy _config
behind get_config/set_config, and Config, loaded at import time. Nothing
linked them, and eleven signatures captured Config as a default argument,
so set_config could not reach the factories, the client, the store or the
MCP server. reranking/base.py went further and snapshotted the configured
reranker name into a class attribute at import.
Config is removed. Internal defaults are config: AppConfig | None = None,
resolved through get_config() per call. RerankerBase._model is None and
CohereReranker takes its model name as an argument, like every other
reranker.
The suite patched attributes on Config while production read the instance
get_config() returns, a different object, so those patches were no-ops
waiting to happen. They now go through get_config().
Parametrize the get_model tests whose only assertion was the returned model
type, extending the table to the reasoning-off, groq-parsed and Bedrock
o-series/qwen/unmapped branches. Fold format_citations_no_title into the
superset test that already covered its scenario.
Add tests for cosine_similarity on parallel vectors, multi-citation Rich
rendering, picture rendering with missing and undecodable bytes, a missing
docling distribution, and the visualize_chunk short-circuits for absent
documents, absent rasters and refless chunks.
Parametrize sibling tests that differed only in a literal value, and fold
two strict-subset tests into the survivors that already covered their
scenario. Every case that ran before still runs; the union of assertions
is applied to each case, strengthening list_all, get_pages_data and
resolve_doc_items.
Replace four hand-rolled log-capture handlers with a shared
capture_logs() contextmanager in conftest.
13 fewer test functions, 348 fewer lines.
reranking.multimodal (vllm provider only) attaches picture bytes to
synthetic picture chunks before rerank; VLLMReranker sends them as
content-parts documents (base64 data URI + description text) in the
same /v1/rerank request as plain text documents.
Convert all LanceDB operations from sync calls wrapped in async
functions to the native async API (connect_async, AsyncConnection,
AsyncTable, AsyncQuery). Database I/O no longer blocks the event loop.
- Store and HaikuRAG use async context managers (async with). Store
initialization is deferred to __aenter__; direct construction
without async with is no longer supported.
- Index creation uses config objects (FTS, BTree, IvfPq) instead of
string-based index_type parameter.
- Upgrade callbacks are async.
- HaikuRAG tracks background vacuum tasks and awaits them in __aexit__
and before destructive rebuild operations to avoid races with
concurrent table mutations.
- temp_db_path fixture uses pytest's tmp_path for reliable async
cleanup.
- Strengthen test_search_returns_search_result with chunk_id, document_id, and
non-empty labels assertions
- Remove test_chunks_include_document_title (subsumed by strengthened test) and
its cassette
- Rename test_chunks_include_document_info to
test_search_chunk_includes_document_provenance; add document_title is None
assertion for untitled documents
- Move test_search_result_get_primary_label from test_context_enhancement.py to
test_search.py; rename, remove unnecessary @pytest.mark.vcr() decorator
