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.

Introduces FileWorker for background file operations with dual-queue
architecture (public/private). Handles refresh, move, and rename tasks
with progress tracking, job completion monitoring, and batch processing.
Compares DB FileGroups to filesystem state using FileGroupDiff to detect
new/modified/deleted files. Designed for memory efficiency on Raspberry Pi.
Python 3.11 is now required, old versions were causing unpredictability in tests. (Sanic does not yet
support 3.12)
Sanic has been upgraded to 23.6.0, which is the latest version that avoids this bug:
https://github.com/sanic-org/sanic/issues/2921
New strategy for multiprocessing is to create all multiprocessing tools in one process, then fork
to other processes. The previous strategy was to declare multiprocessing tools at the top of every
file, or wherever they were needed at import/creation. Now all multiprocessing tools are attached to the
app.shared_ctx. This means `api_app` is imported in many, many places.
This forced a change in how the DownloadManager works. Previously, it would continually run
download workers which would pull downloads from a multiprocessing.Queue. Now, a single worker checks
for new downloads and sends a Sanic signal.
Flags have been reworked to use the `api_app`. I removed the `which` flag functionality because the
`which` are called at import and needed their own multiprocessing.Event.

Using zim file names as FileGroup.title.
Removing accidental output commit.
* A new zim module has been added, this module allows several things to interact with Zim files.
* Allow searching of Zim files using libzim.
* Allow downloading of Kiwix projects (wikipedia, wikibooks, etc) on a schedule which replaces the outdated files.
* Creation of a new zim docker container which allows viewing of the Zim file contents.
* This commit also adds move/rename/mkdir features in the File Browser.
* File tags are preserved when moving/renaming.
