The file_holders table is now the only tracker of per-file peer relationships. post_upstream, post_downstream, blob_upstream, and blob_downstream are dropped at first launch after the seed migration copies any existing entries. Schema: - DROP TABLE IF EXISTS on all four legacy tables after seeding - Seed migration guards with sqlite_master table_exists check so fresh installs don't crash trying to read non-existent sources - Remove CREATE TABLE statements for the four tables from init - Remove Protocol v4 Phase 6 post_upstream priority migration (dead) - Remove blob_upstream preferred_tree column migration (dead) Rust: - Remove add/get/remove post_upstream, post_downstream, blob_upstream, blob_downstream methods - Remove get_blob_upstream_preferred_tree / update variant - Rewrite get_eviction_candidates's downstream_count subquery to count file_holders entries - Rewrite apply_delete's cascade cleanup to clear file_holders instead of post_upstream/post_downstream - cleanup_cdn_for_blob now clears file_holders for the CID Callers: - All dual-write sites in connection.rs and node.rs now do touch_file_holder only (legacy writes removed) - get_stale_manifests replaced with get_stale_manifest_cids; caller in node.rs picks a refresh source from file_holders Tests: - Remove blob_upstream_crud, blob_downstream_crud_and_limit, blob_upstream_preferred_tree, remove_blob_upstream, post_downstream_crud - Add file_holders_lru_cap and file_holders_direction_promotion tests All 110 core tests passing. Workspace compiles clean. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> |
