Add vector-index creation tests including the warned failure, chunk
repository get_by_id, list_all pagination, blank-query and precomputed-vector
search, the unknown-score-column guard, settings row recreation, and
replace_for_document with no items.
Delete repository methods with no callers (SettingsRepository CRUD,
ChunkRepository.update/delete/get_chunks_in_range), the DataFrame branch of
_process_search_results whose only caller always passes a query, and guards
that cannot be reached from their call sites: the rebuild mode=None default,
the staging drop already performed by _resolve_rebuild_recovery, the empty
batch skip, two context fast paths, the doctor prefix guard, the poller
_task attribute that is never assigned, and a docling caption fallback for
a field name no item class defines.
set_haiku_version built a recreated settings row from the process-global
Config rather than the store's own, so a store opened with a custom config
stamped global settings into the database.
check_source_accessible called urlparse outside its try block, so a stored
URI with a malformed IPv6 host raised ValueError instead of reporting the
source as inaccessible, aborting the whole rebuild sweep.
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.
