bvandeusen e35fb1edf7 fix(scan): recovery sweep for stranded download events
The scan tick (scan.py:_tick_due_sources_async) inserts
DownloadEvent(status='pending') and fires download_source.delay(). If the
task dies before finalizing the event — worker OOM/SIGKILL, lost task, or
a gallery-dl that didn't unwind on the 1200s hard time_limit — the event
stays in-flight forever. Every later tick then skips the source via the
in-flight guard (scan.py:168), so Source.last_checked_at is never written
and the operator sees "last check never" in the Subscriptions health
column, permanently.

cleanup_old_download_events only prunes terminal events (by design); no
existing sweep covered the pending/running case. Operator confirmed
2026-05-29 with a diagnostic query: all 43 "never checked" sources were
stranded behind stale in-flight events (eligible_stuck_inflight = 43,
every other bucket zero).

New recover_stalled_download_events task (Beat every 5 min):
- Flips DownloadEvent rows pending/running > 30 min (10 min past the
  download_source 1200s hard kill, so legitimately-running tasks are
  never touched) to status='error' with a sentinel message.
- Bumps each affected Source's consecutive_failures ONCE per source —
  backoff is 2^N on that counter so per-event bumps would needlessly
  inflate the next interval — sets last_error, stamps last_checked_at.

UPDATE...RETURNING source_id avoids a SELECT-then-UPDATE-WHERE-IN that
would hit the psycopg 65535-param ceiling on a large strand pile.

Net: the 43 currently-stranded sources unstick on the first sweep after
deploy, their health dots flip amber instead of unchecked, and the next
scan tick re-queues them.

FabledCurator

Self-hosted media curation — gallery, ML tagging, and subscription-driven downloading in one app. Part of the FabledSword family.

Combines what was ImageRepo (gallery, ML, importer) and GallerySubscriber (gallery-dl wrapper, subscriptions, credential capture) into a single product.

Status

Pre-v1. Not yet functional.

Quick start

For local development and testing, just:

docker compose up -d
# UI: http://localhost:8080

That uses sane dev defaults baked into docker-compose.yml and the dev override (docker-compose.override.yml, auto-merged) — local builds, DEBUG logging, exposed Postgres + Redis ports on the host. No .env required.

For a production-like deployment, override the dev defaults via shell env or a .env file (see .env.example for the variable names) and use:

docker compose -f docker-compose.yml up -d
# (skips the override so containers pull registry images)

Deployment posture

FabledCurator is designed to run inside a self-hosted homelab environment over plain HTTP. If you want TLS, terminate it at your reverse proxy. The app does not generate certificates, redirect to HTTPS, or set HSTS.

CI / Forgejo setup

The repo's workflows expect:

  • Runner label python-ci — a Forgejo runner with Python 3.14, ruff, and Node 22 pre-installed. Both ci.yml and build.yml use this label. The runner image (runner-base:python-ci) is built from CI-Runner/CI-python/ in the operator's workspace; make push from that directory builds and pushes a new image when toolchain pins change.

  • Repo secret RELEASE_TOKEN — a Forgejo PAT with the following scopes:

    • write:package + read:package — for docker push to git.fabledsword.com
    • write:release — for future release-cutting workflows
    • write:issue — for future issue-management automation

    Generate at https://git.fabledsword.com/user/settings/applications. The injected GITHUB_TOKEN cannot be used because it lacks write:package.
