Today the ingest core does `if not media: continue`, so a post with no downloadable media (a pure-text post — which often holds the ONLY copy of an external mega/gdrive/pixeldrain link) never upserts a Post. Now the native ingester emits a post-only sidecar (`_post.json`) for every media-less post, gated through the seen-ledger via a synthetic `post:<id>` key so the body is detail-fetched + recorded ONCE (not re-walked every tick); recovery bypasses the gate. Phase 3 imports these via Importer.upsert_post_record, keyed on external_post_id so it UPDATES the same Post a media import would create — never doubles, never clobbers a populated body with an empty one. - gallery_dl.py: DownloadResult.post_record_paths (default []; gallery-dl path unaffected — all constructions are keyword). - ingest_core.py: media-less branch (optional client/downloader seams via getattr; stub clients in tests skip it as before). - patreon_client.py: post_record_key(post). patreon_downloader.py: write_post_record + _write_sidecar_data refactor (shared serializer). - importer.py: upsert_post_record. download_service.py: phase-3 import loop. - tests: client/downloader/ingester (gate + recovery)/importer (no-double). Slice 0b of milestone #64. Refs FC #830. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

"""Native Patreon media downloader (build step 2b of the native ingester).
|
|
|
|
Given a Patreon post and its already-resolved `MediaItem`s (from
|
|
patreon_client.extract_media), download the media to the EXACT on-disk layout
|
|
gallery-dl produces, write a sidecar JSON the existing importer consumes, and
|
|
report per-media outcomes.
|
|
|
|
This module is PURE: no DB. The cross-run seen-ledger and the iter_posts
|
|
orchestration are a LATER step. The tier-1 (seen) skip is an INJECTED predicate
|
|
(`is_seen`), so this module needs no DB and is unit-testable without network.
|
|
|
|
On-disk layout (matches gallery-dl):
|
|
<images_root>/<artist_slug>/patreon/<DIR>/<NN>_<filename>
|
|
where <DIR> = "<YYYY-MM-DD>_<post_id>_<title40>" (date prefix omitted when the
|
|
post's published_at is unparseable), <NN> is the 1-based index of the item in
|
|
the post zero-padded to 2, and <filename> is MediaItem.filename. The sidecar
|
|
is written next to the media as <NN>_<stem>.json (media_path.with_suffix).
|
|
|
|
Video: a MediaItem whose URL is a Mux/HLS stream (host stream.mux.com or path
|
|
endswith .m3u8) is fetched with yt-dlp (subprocess), passing the same
|
|
Referer/Origin headers gallery-dl forwards for Mux playback (see gallery_dl.py
|
|
_get_default_config). yt-dlp may remux to a container of its own choosing, so we
|
|
accept the actual output extension and record the real path.
|
|
|
|
FC runs on a plain-HTTP homelab; nothing here uses a secure-context Web API.
