Decentralized social media network — no central server, user-owned data

Protocol v4 sync overhaul: - Slim PullSyncRequest: per-author timestamps (since_ms) replace full post ID lists Request size O(follows) instead of O(posts). Backward-compatible via serde default. - Tiered pull frequency: 60s ticks, only syncs stale authors (4hr default) Full pull only on first tick (bootstrap). Most ticks skip — no stale authors. - Tiered engagement checks: frequency scales with content age 5min (<72h), 1hr (3-14d), 4hr (14-30d), 24hr (>30d) Single SQL query filters posts due for check. - Header-driven post discovery: ManifestPush triggers PostFetch for missing followed-author posts (capped 10 per manifest). CDN tree = notification system. - Multi-upstream (3 max): composite PK, priority ordering, engagement diffs sent to all upstreams, promote/remove on failure. DB schema: - follows.last_sync_ms — Self Last Encounter per author - posts.last_engagement_ms — last reaction/comment timestamp - posts.last_check_ms — last engagement check timestamp - post_upstream: single-row → 3-row with priority column Lock contention fixes: - get_blob_for_post: 3 locks → 1 - prefetch_blobs_from_peer: lock-free blob checks - fetch_engagement_from_peer: explicit lock release before I/O - serve_post: 4 locks → 2 (eliminated redundant queries) - run_replication_check: 2 locks → 1 - Badge cycle: N+2 IPC calls → 1 (get_badge_counts) Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> |
