get_image_link_matches streamed one sqlite3_step per linked row, and
Python's sqlite3 releases and retakes the GIL around every step. While
ComfyUI generates, each retake waits on the busy thread, so the
first-page link read of the workspace Images page stretched from tens of
milliseconds to seconds.
SQLite now returns the unchanged filter SELECT's rows as one JSON value
(json_group_array), decoded with json.loads: a constant two or three GIL
hand-backs instead of one per row. Nothing is cached. Any
OperationalError from the wrapped statement, or a BLOB file_path or
rating, makes that read stream as before with one warning per process; a
missing JSON function stops the attempt for the rest of the process.
tests/test_database_link_matches.py proves the result equals the
streamed read on every filter combination and on NULL ratings, quoted,
backslashed, non-ASCII and multi-line paths, ambiguous and pair links,
an empty database and both fallbacks; the structural budget test also
checks the wrapped query plan.
