Every section inherited plain BaseModel, so unknown keys were dropped
silently: providers.docling_serve.timeout was documented for months while
being ignored, and a typo in any setting took the default. Sections now
derive from ConfigModel, which forbids extras, so a stale or misspelled key
fails with its path. This already found search.context_radius in a live app
config and providers.vllm in soliplex's example.
converter, chunker and chunker_type are Literals. Sizes, limits,
dimensions, token budgets, attempt counts and breaker thresholds must be
positive; retention, delays, intervals and cooldowns non-negative;
similarity_threshold within 0-1; port within 0-65535. port 0 keeps its
OS-assigned meaning and worker_count allows 0 for an API-and-reaper-only
process.
get_reranker caught ImportError and returned None, so a configured reranker
whose extra was missing silently disappeared. It now propagates.
raise_missing_extra names the install command and re-raises when the failure
came from inside an installed package, so a broken transitive import is not
reported as a missing one. zeroentropy imported bare and now guards like the
others.
The haiku.rag package declares the jina extra. jina-local already worked
there through cross-encoder's transitive transformers and torch; the
resolved package set is unchanged, but the support is now promised rather
than inherited.
Provider fields stay unconstrained: get_model ends in a pass-through to
pydantic-ai for any provider it supports, so a Literal there would reject
valid configurations.
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().
check_source_accessible narrowed its handler to ValueError, but Path.exists
re-raises errno values outside its ignored set (EACCES, ENAMETOOLONG). Those
were swallowed before and now escaped into the rebuild sweep the guard exists
to protect. Catch OSError too.
Restore the arity guard in _common_path_prefix: without it an empty list
raises from min() and a single label yields a prefix covering the whole path.
Two tests would have hung rather than failed on regression (the vacuum skip
and the protected-wait cancellation); both are now bounded. The import
vacuum test raced against the done-callback that discards the task, and now
spies on the call instead, with a negative control.
Replace assertions that could not fail: blank-query search against an empty
corpus, a batch flush counted against an empty table, a picture description
asserting its own input state, and an FS scheme check with nothing on disk to
resolve. The get_model matrix asserted only the returned type across 26
cases and now pins the per-provider settings. The three batching tests now
count flushes, which revealed embed-only writes through chunks_table.add
rather than _flush_rebuild_batch.
Add tests for the MCP tools' degradation contracts, malformed WebDAV
multistatus bodies, dry-run poller sweeps including the circuit-open and
discover-failure paths, FS source scheme and symlink handling, docling-serve
zip parsing, and the remaining embedding and reranker helpers. Parametrize
_strip_etag.
Drop the misplaced pragma on the analyze handler, which sat on the return and
left the except uncovered. Add one on the FS symlink OSError guard, which
resolve(strict=False) absorbs for every real link.
- Add `chunker_type` config field to choose between "hybrid" (default) and "hierarchical" chunking strategies
- Add `chunking_merge_peers` config field for HybridChunker (default: true)
- Add `chunking_use_markdown_tables` config field to control table serialization format (default: false, matching docling's default)
