* feat(grep): integrate VikingDB bm25 keyword search for grep engine
* fix(grep): address CI review feedback: max-size eviction to _count_cache, use Literal, Split regex alternation into individual keywords for bm25 (max 10)
* fix(schema): use dynamic __version__ for schema_version and handle dev suffixes in version comparison
* fix(schema): upsert data to vikingdb lack of content
* chore: add benchmark for retrieval
* fix(grep): vikingdb return 200 and no results means no matching content, not necessary to fallback to local fs
* fix(benchmark): sub uri args; add report
* refactor: code format by ruff
* optimize: move grep config (engine and switch_to_remote_threshold) to ov.conf
* optimize: auto adapt remote_return_limit by agg API; rm unnecessary params in keywords search
* fix: adjust benchmark scripts
* fix(grep): store full content for BM25; use PathScope depth; reduce redundant API calls
* refactor: new benchmark
* fix: step1 add resource by real code data
* feat(benchmark): split grep benchmark into effectiveness/performance suites with async reindex
* optimize (benchmark): adjust keywords and ground truth for testing
* fix: truncate 64KB for content field
* optimize: effectiveness add resource plainly
* optimize: change param use of SearchByKeywords from "keywords" to "query"
* optimize(benchmark): refactor effectiveness scripts
* optimize: ensure raw data for content field
* optimize: fulltext analyzer's stop-words only use symbols
* fix: adapt to new ov cli for benchmark
* optimize: reuse file content to avoid re-read AGFS file
* optimize: tune grep vikingdb defaults and refresh bm25 benchmark scripts
* optimize: benchmark client timeout
* update README
* fix: rm unused param
* fix: default values in docs
* optimize: increase truncate byte size to 1MB for content field for VikingDB
* fix(logger): harden queued stream logging (#2786)
* fix(logger): replace StreamHandler with QueueHandler+QueueListener to prevent thread deadlock
When log.output='stdout' (default) and the server is managed by systemd,
concurrent log writes can deadlock because logging.StreamHandler holds a
thread lock across stream.flush() which blocks on systemd-piped file I/O.
During session.commit() phase 2, multiple async coroutines (memory
extraction, summarization) concurrently call logger.info()/warning()
with large payloads. The first thread's flush() blocks on the pipe,
while all subsequent threads block on handler.acquire() forever.
This permanently silences the server log and prevents _write_done_file()
from executing, leaving phase 2 hanging without .done.
Fix: use QueueHandler + QueueListener from stdlib logging.handlers
(Python 3.2+). QueueHandler.emit() does queue.put(record) with no lock
or I/O, returning immediately. QueueListener has a dedicated single
thread as the sole consumer touching the real StreamHandler, making
lock contention impossible.
Changes in _create_log_handler(): stdout/stderr branches now create
a shared QueueListener with unbounded queue, returning QueueHandler
instances to callers. _build_standard_handler() delegates formatter
and filter setup to the real handler in the listener thread.
Closes: #2752
