bvandeusenandClaude Opus 5.5	5259caa846	fix: dead external links are retried sparingly, not three times a day ... The daily recovery reset every dead link to a fresh three-attempt budget, so a link that can never succeed (an archive too big to import inside the fetch's hard limit, a file made private) was downloaded up to three times a day, every day. Recovery now gives a dead link one more attempt once it has been dead for 2**recoveries days (1, 2, 4, 8, 16), and stops after five. A recovered link that fails again goes straight back to dead. Retention prunes only links recovery has given up on, 30 days after their last attempt. A manual refetch of a post restores the full budgets. Migration 0118 adds external_link.recoveries.

bvandeusenandClaude Opus 5.5	157f2803c0	fix: downloads stop leaving files on disk that the library doesn't use ... - An archive whose images were extracted was kept at its download path as well as in the attachments store. Both download paths now remove the downloaded copy. - A downloaded file the import filters reject (too small, transparent, single colour, unreadable) was left on disk with no record. A later walk found it, imported it again and rejected it again, every time. Rejected files are now removed; the seen ledger keeps them from being downloaded again. - Both paths share one policy, Importer.discard_after_attach, which never removes a file an ImageRecord points at. - An external-link fetch that fails, or whose worker was killed, left partial files (megatools' .megatmp.*) in the link's dir, and a killed fetch left its link 'downloading' for good. A fetch now clears unrecorded leftovers before starting and after failing. The sweep returns a link to retry once it has been 'downloading' past the task's hard limit, using a new external_link.started_at column (migration 0117). - The orphaned temp-file sweep now recognises .megatmp.* as well as .part and .partial.

bvandeusenandClaude Opus 5	08418d54a3	db: index the seven unindexed FKs, drop the seven redundant ones (#3300, #3301) ... A structural sweep of the deployed schema, run AFTER 0088 got the models and the chain to exact agreement. That agreement is what 0088 achieved, and it is worth naming what it does not prove: a models-vs-chain diff shows the two describe the same schema, not that the schema is right. Everything here was wrong in BOTH. The one that matters: image_tag has PRIMARY KEY (image_record_id, tag_id) and no other index, so tag_id is unindexed. That is the gallery's tag filter (tag_query.py builds `image_tag.c.tag_id == tid`) and the ON DELETE CASCADE from tag, both scanning the largest table in the schema. Six more FKs were unindexed on smaller tables; presentation_review.tag_id also CASCADEs. Dropped, on the other side: ix_image_record_sha256 was an exact duplicate of the index uq_image_record_sha256 already builds — two btrees on the same column of the highest-insert-rate table. The other six are single-column indexes a later composite superseded without the narrow one being retired; a btree on (a,b) already serves lookups on a. 0088 deliberately taught the models to declare BOTH sha256 indexes so they would describe reality. This changes the reality instead, and the models change with it — otherwise the next baseline.yml run reintroduces exactly the drift 0088 removed. CONCURRENTLY throughout, so building the image_tag index does not hold an ACCESS EXCLUSIVE lock over every write for the duration. The cost is that the migration cannot run in a transaction and so is not atomic: every statement is IF NOT EXISTS / IF EXISTS, making a re-run after a partial failure safe. The docstring carries the query for finding an INVALID index left by an interrupted CONCURRENTLY build. What the sweep found clean, for the record: all 43 tables have a primary key; all 51 FKs declare an explicit ON DELETE, so none silently blocks a delete; the three enum CHECKs match the code that writes them (rule 36).

bvandeusenandClaude Opus 5	b979062dd7	db: rename the four double-prefixed CHECK constraints (#3275) ... Run 5026 got the models-vs-chain diff to 7 lines. Three findings, and one of them reverses an assumption I made in the previous commit. The doubled CHECK names are what the DATABASE has, not what the generator invented. base.py's convention is ck_%(table_name)s_%(constraint_name)s, which — unlike uq/fk/ix — applies even to a constraint that already has a name, so four migrations that passed an already-prefixed name got it prefixed twice: ck_import_settings_ck_import_settings_singleton ck_ml_settings_ck_ml_settings_singleton ck_post_ck_post_translation_override ck_tag_ck_tag_fandom_requires_character The workflow repair added last commit is still correct and still needed — autogenerate really does re-double a name on the round trip — but it was making the MODELS side clean against a chain that is dirty. The comment in ml_settings.py claiming its bare name "matches migration 0003" was simply false; 0003 produces the doubled form. Nothing reads a CHECK constraint by name, so this has never done harm. But it is precisely the development-era residue the collapsed baseline exists to leave behind, and a public schema should not ship it — so 0088 renames the deployed constraints and all six models now declare bare names. RENAME CONSTRAINT is catalog-only: no scan, no rewrite, no revalidation, which is why this is safe on post and tag. Guarded on pg_constraint scoped by conrelid, so it is a no-op on a database built from the models. ix_tag_fandom_id showed as a difference only because chain_ref was pinned to 0a5bbe8, which predates 0088 — the comparison was measuring the models against a chain missing the migration that closes the gap. chain_ref now defaults to blank, meaning "the chain in this ref". Pin it to a commit only after the collapse, when the tree no longer carries the revisions.

bvandeusen	5e1996e77f	db: reconcile the models with the deployed schema (#3275) ... Milestone 328's acceptance test compared a database built by the real 0001..0087 chain against one built from the models, and found ~130 places where they disagree. This closes them. Almost all were the MODEL being wrong, so almost all of this is model edits with no DDL — the database already had these things, nothing in it changes, and no deploy is needed for this part: * 92 columns gained server_default. The models carried Python-side `default=` only, so the ORM filled the value and the column had no database default. Anything inserting outside the ORM behaved differently from production. * Eleven indexes that existed only in migrations are now declared: the three backup_run reporting indexes, the two date-ordered image_record browse indexes, import_task and presentation_review, and the three task_run history indexes. All use text() for their DESC ordering and postgresql_where for the partial one. * Two UNIQUE indexes that autogenerate silently proposed DROPPING, because neither is expressible as a UniqueConstraint: uq_tag_name_kind_fandom — an EXPRESSION index over (name, kind, COALESCE(fandom_id, 0)) uq_post_artist_external_id_null_source — PARTIAL, WHERE source_id IS NULL post.py already had a comment describing the second one. The comment was right; nothing declared it. * The two external_link enum CHECKs (host, status) — rule 36 territory, and absent from the model entirely. * Two indexes were named explicitly. A bare index=True generated ix_tag_alias_canonical_tag_id where the database has ix_tag_alias_canonical, so autogenerate proposed a drop+create of an index that was already there under another name. Same for tag_suggestion_rejection. Only ONE thing needed DDL, as 0088: tag.fandom_id is declared index=True but no migration ever created that index. Deliberately NOT here: image_record.sha256. The model says unique=True; 0001 created a plain index. Duplicates are possible today and the ORM believes otherwise. The fix depends on whether duplicates already exist — if they do, that is a dedupe decision, not a constraint — so it waits on an answer about live data. The real severity of #3275 is not the squash. It is that --autogenerate has been unsafe on this project: run against the old models it would have proposed dropping eleven indexes and two uniqueness guarantees.	2026-08-30 14:42:30 -04:00
bvandeusenandClaude Opus 4.8	d96918d777	feat(posts): extract + record external file-host links (Phase 3) ... Capture off-platform links (mega/gdrive/mediafire/dropbox/pixeldrain) embedded in post bodies so they're never silently dropped, and surface them in the post view. The download worker (Phase 4) walks these rows. - link_extract.py: pure extractor — <a href> + bare URLs, unwraps Patreon redirect shims, PRESERVES the full url incl. #fragment (mega's key), dedups. Reusable by every platform (runs off Post.description). - external_link model + migration 0049: post_id/artist_id/host/url/label/status /attempts/last_error/attachment_id/timing; CHECK whitelists (full enum incl. worker statuses up front) + (post_id,url) unique. - importer._sync_external_links: insert-missing on both import paths (_apply_sidecar + upsert_post_record) so a re-import never resets a link's status; runs for all platforms. - post_feed_service.get_post: returns external_links (detail-only). - PostCard: renders the links (host chip + label + status) once expanded. - tests: extractor (5 hosts, fragment, shim unwrap, dedup), importer (record + no-dup on reimport), serializer.
