Behaviour tests for export (json/csv/errors), duplicate detection and
merging, image metadata storage and lookup, missing-file cleanup,
statistics, bulk operations, orphan pruning, consistency checks,
subfolder listing, tag queries and management edge cases, legacy tag
column parsing, config-driven path resolution, model housekeeping and
the TEXT -> INTEGER prompt_id migration. database/operations.py and
database/models.py are both above 85% statement+branch coverage.
generated_images was UNIQUE(prompt_id, filename) on the basename, so
ComfyUI's same-named files in different date folders were silently
ignored by INSERT OR IGNORE, and the lastrowid == 0 branch after it
never ran. The table now carries file_path (normcase/normpath/abspath
of the image path) with UNIQUE(prompt_id, file_path); the migration
collapses rows that normalise to one file and supersedes the old
basename migration, which would otherwise undo it on every start.
search_prompts and the tag search escaped nothing, so 100% matched
'100 percent' and a_b matched aXb; user text now goes through
escape_like with ESCAPE. save_prompt no longer stamps last_used_at, the
usage backfill runs only on the upgrade that adds the columns, and the
Recently Used / Most Used orders put never-run prompts (NULL) after run
ones instead of first.
Node execution, the queue hook and the image monitor all do
get_prompt_by_hash() then save_prompt(). When two of them race on the
same text the second INSERT failed on UNIQUE(hash) and surfaced an
IntegrityError. save_prompt now catches it, re-fetches by hash and
returns the existing id, so eight threads saving one prompt end with a
single row and every record_prompt_use counted.
PromptModel.get_connection() handed every thread the same
check_same_thread=False connection, so a commit or rollback from the
watchdog, executor or queue-hook thread could land on another thread's
half-done write (sqlite3 raised 'bad parameter or other API misuse'
under concurrent saves). Connections now live in threading.local, each
with WAL, Row factory, foreign_keys and busy_timeout, and are tracked so
they can be closed. PromptModel.close() / PromptDatabase.close() close
the calling thread's connection so tests and restores can delete the
file on Windows.
