- admin_safe_set_is_admin: short-circuit when target.is_admin == value,
before writing audit. PATCH {is_admin: true} on someone already admin
previously wrote a misleading "promote_user" row even though the UPDATE
was a no-op.
- list_chapters (/admin/mangas/:id/chapters): explicit exists() check on
manga_id, returns 404 instead of 200 [] for a typo'd / deleted manga.
- ChapterSyncState priority: the Failed branch now requires page_count = 0,
so a chapter with pages on disk AND a historical dead job (from a
re-download attempt that crashed) stays Synced. The old order
contradicted Synced's documented "downloaded at some point" contract.
Doc comments updated alongside the SQL.
Three new regression tests pin the behaviour.
Adds GET /api/v1/admin/mangas and /admin/mangas/:id/chapters guarded by
RequireAdmin. Sync state is computed at query time from the existing
crawler signals (manga_sources / chapter_sources / crawler_jobs) — no
new state column is persisted, so the crawler stays the single writer
of these signals.
Per-manga priority: InProgress (in-flight sync_manga or
sync_chapter_list job) > Dropped (all source rows soft-dropped) >
Synced (default; covers user-uploaded mangas with zero source rows).
Per-chapter priority: Downloading (in-flight sync_chapter_content) >
Dropped (all source rows soft-dropped) > Failed (most-recent terminal
job is dead) > NotDownloaded (page_count = 0) > Synced. The Failed
check sits ABOVE NotDownloaded so the more informative "we tried and
it died" state wins over "we never got around to it" — see the
priority comment in repo/admin_view.rs.
Migration 0020 adds a partial index on
crawler_jobs((payload->>'source_manga_key')) for the one job kind
(sync_manga) whose payload doesn't carry manga_id directly — without it
the in-flight detection for a manga falls back to a seqscan over the
job table.
