fix(external): split fetch timeout into read (60s) + total (30m) budgets (#883)
The single _FETCH_TIMEOUT=3000s meant different things per host: a TOTAL
wall-clock for mega (subprocess), but only a per-read socket timeout for HTTP
hosts (requests' timeout is the idle gap between bytes, never a total). So a
stalled HTTP connection tied up a download-worker slot AND the per-host
serialize lock for ~50 min before failing (operator-flagged 2026-06-17).

Split into two limits in external_fetch:
- read timeout (_READ_TIMEOUT=60s, with _CONNECT_TIMEOUT=30s) → requests gets
  (connect, read); a stalled socket now fails in ~60s.
- total budget (_TOTAL_TIMEOUT=30min) → enforced as a wall-clock deadline
  across chunks in _stream_to_file (HTTP has no total-download timeout), and
  passed as the subprocess total for mega.
fetch_external() signature: timeout= → read_timeout=/total_timeout=. gdrive
(gdown) self-manages; the celery hard limit is the outer backstop.

Also lowered the per-host lock TTL 3600→2400 so a worker that dies holding it
can't wedge a host's links much past one fetch's budget.

Each external link is already one Celery task (sweep enqueues one
fetch_external_link.delay per link), so these budgets are per-link.

Tests: total-budget-exceeded cleans the .part; HTTP gets (connect, read);
mega gets the total. Worker fakes updated to **kwargs.

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.
