Paul Nothaft 446d80a4cc feat: presigned download UI + S3 prefix walker auto-importer (follow-ups)
Closes the user-facing surface for the two #328 follow-ups previously
landed in code form (presigned route + S3 mode notes), plus the schema
migration that backs both #328 and #327 follow-ups.

Migration 083
- events.allow_presigned_download — per-event opt-in for the
  presigned-URL "Download All" path. Off by default because it bypasses
  watermarks; admins flip it knowingly. Mutually exclusive with
  watermark_downloads.
- webhooks.filter (jsonb default {}) — dot-path equality predicate
  evaluated at fire time. Empty object = no filter, fire always.
  Backs the filter logic that shipped with #327.
- webhooks.template (text nullable) — optional ${dot.path} string
  substitution applied at delivery time. NULL = use the default JSON
  envelope (back-compat). Backs the template logic from #327.

S3 prefix walker (services/s3AutoImporter.js)
- Replaces the chokidar file-watcher in S3 mode (where there's no
  inotify equivalent on remote objects).
- Polls every active event's S3 prefix every 5 min by default
  (STORAGE_AUTO_IMPORT_INTERVAL_MS overridable).
- Eventual-consistency gate: an object is only imported after it's
  been seen for two consecutive polls. Avoids flapping when S3 returns
  a freshly-uploaded object that disappears on the next list (a
  documented S3 behavior on certain backends).
- Skips generated artifacts (thumb_*, hero_*, dot-files).
- Inserts photos rows + fires photo.uploaded webhooks the same way
  the local fileWatcher does.
- Opt-in via STORAGE_AUTO_IMPORT=true. Off by default because it adds
  API call cost.

EventDetailsPage UI (frontend)
- Round D queryKey alignment for #325 dedup — replaces useQuery on
  publicSettingsService with the shared usePublicSettings() hook so
  the page joins the same React Query cache as every other consumer.
- Per-event "Allow direct S3 download (no watermark, S3 mode only)"
  toggle in Download Protection. Disabled when watermark_downloads is
  on; tooltip explains the bandwidth/watermark trade-off. Toggling
  watermark_downloads on automatically clears allow_presigned_download
  to keep the two mutually exclusive in the UI.

Verified live against MinIO
- Presigned: GET /api/gallery/.../download-all → 302 with
  Location: http://minio:9000/...?X-Amz-Signature=...&X-Amz-Expires=300.
  Following the URL inside the docker network → HTTP 200, valid
  PK ZIP archive containing the photo.
- Auto-importer: dropped a file via `mc cp` directly into the bucket;
  watcher imported it after 2 polls; webhook subscribed to
  photo.uploaded fired with source=s3-auto-import; receiver got POST
  with valid HMAC, status=success, 3ms latency.

Database Migrations

This directory contains database migrations for the PicPeak photo sharing platform.

Directory Structure

/core

Essential migrations that are always run for new deployments. These include:

  • init.js - Initial database schema creation
  • Backup service tables (029-035)
  • Gallery feedback tables (033)
  • Pre-generated watermarks (061)

/legacy

Migrations needed only when upgrading from older versions. New deployments can skip these as the core schema already includes all necessary tables and columns.

For New Deployments

If you're deploying this application for the first time:

  1. The initializeDatabase() function in src/database/db.js will create all necessary tables
  2. Only migrations in the /core directory will be run
  3. This ensures a clean, optimized database schema

For Existing Deployments

If you're upgrading from an older version:

  1. All migrations (both core and legacy) will be run in sequence
  2. The migration system tracks which migrations have been applied
  3. Only new migrations will be executed

Running Migrations

# Development
npm run migrate

# Production
npm run migrate:prod

Note on Duplicate Migration Numbers

The legacy directory contains renamed duplicates:

  • 014_add_host_name_to_events_duplicate.js (was duplicate of 014)
  • 027_add_rate_limit_settings_duplicate.js (was duplicate of 027)

These have been renamed to avoid conflicts while preserving the migration history.
