Postgres -> SQLite hard cutover: the database moves into the media directory.
The database now lives at <media>/config/wrolpi.db so a library (files,
configs, AND database) travels with the drive between WROLPi systems.
Core:
- wrolpi/db.py: lazy SQLite engine factory (WAL, busy_timeout=30s,
foreign_keys=ON); get_db_curs yields a plain sqlite3.Cursor; native
sqlite3 paramstyle everywhere (no compatibility shims); global sqlite3
adapters keep raw-SQL datetime formats identical to the ORM's.
- wrolpi/fts.py: FTS5 external-content search replacing tsvector/GIN.
Injection-proof websearch->FTS5 translator, bm25(10,4,2,1) reproducing
A/B/C/D weighting, fast(abc)/deep column filtering, snippet headlines.
Stemming contract pinned by dedicated tests (watch/watches/watched/
watching are interchangeable).
- wrolpi/schema_ddl.py: SQLite triggers shared verbatim by the alembic
baseline and test DBs; fixes the channel video_count DELETE/UPDATE
bugs and a latent total_size bug (it used the video id as channel id).
- wrolpi/db_bootstrap.py: startup auto-create/migrate; refuses databases
written by a newer WROLPi (db_version_mismatch); SQLite 3.40 floor;
network-filesystem refusal; never creates/migrates/trusts a database
beneath an unmounted production media directory (shadow-DB guard).
- Alembic: 85 Postgres-era migrations squashed into one baseline;
revision ids are dates (2026_07_10_1350) so filenames self-sort and
alembic_version says when a schema was created; render_as_batch=True.
- All raw Postgres SQL rewritten (ANY->json_each IN, array_agg @> ->
HAVING COUNT(DISTINCT), unnest->executemany/UPDATE..FROM,
generate_series histograms->strftime GROUP BY, DISTINCT ON->
row_number(), writable CTEs->two statements, jsonb_*->json_*, explicit
NULLS FIRST/LAST, LIMIT-before-OFFSET). Simple statements converted
to SQLAlchemy instead (flag upsert, download retry/summary/tag checks,
channel-by-tag estimate, Directory delete).
- Config imports count skipped entries; background dumps are blocked
after a lossy import so partial imports can never overwrite YAML
configs (they are the sole source of truth for rebuilds now).
- Search tolerates explicit JSON nulls for limit/offset (Postgres
treated OFFSET NULL as 0; SQLite errors).
- file_group.id/doc_section.id render as INTEGER PRIMARY KEY on SQLite
(BIGINT is not a rowid alias; FTS5 content_rowid requires it).
Ops teardown: docker-compose db service, CI postgres sidecars,
initialize_api_db.sh, controller postgresql service, psycopg2-binary all
removed. upgrade.sh stops/disables postgresql (data is NOT deleted;
`systemctl enable --now postgresql` restores it); systemd units no
longer Want postgresql.service.
Existing-user upgrade: first boot creates+migrates the DB, configs
import (tags recreate their FileGroups from disk), a refresh rebuilds
the library index. QA'd on the 10.0.0.8 RPi: rebuild matched the
Postgres baseline exactly; survived an uncontrolled hard reboot with
clean integrity checks.
Accepted behavior changes: FTS5 has no stopwords; bm25 length
normalization shifts some rank orders; fast-path d_headline is
un-highlighted; all-negative queries match nothing.
Deferred: Debian/trixie package lists (incl. sqlite3 CLI), Cypress
re-baseline, VACUUM INTO snapshots, exFAT/NTFS warning, auto-kicked
rebuild refresh with progress UX.
