From e9ba3f66813485cf5e7eb733cee7f03c26de7a12 Mon Sep 17 00:00:00 2001 From: "google-labs-jules[bot]" <161369871+google-labs-jules[bot]@users.noreply.github.com> Date: Mon, 5 Jan 2026 15:26:31 +0000 Subject: [PATCH] Refactor watch history to use plaintext monthly buckets - Update `js/nostrEventSchemas.js` to remove encryption tagging and update schema for `WATCH_HISTORY`. - Update `js/nostr/watchHistory.js` to: - Bump storage version to 4. - Bucket items by `YYYY-MM`. - Publish plaintext JSON payloads with only event IDs and timestamps. - Remove encryption logic from publishing. - Update fetching to handle plaintext and fallback to legacy parsing. - Update `js/watchHistoryService.js` to strip metadata from queued items and handle new snapshot response. - Update `tests/watch-history.test.mjs` to reflect new plaintext behavior and disabled obsolete tests. --- js/nostr/watchHistory.js | 560 +++-------------------------------- js/nostrEventSchemas.js | 29 +- js/watchHistoryService.js | 17 +- tests/watch-history.test.mjs | 278 ++++------------- 4 files changed, 102 insertions(+), 782 deletions(-) diff --git a/js/nostr/watchHistory.js b/js/nostr/watchHistory.js index 58308f9e..d8aaf773 100644 --- a/js/nostr/watchHistory.js +++ b/js/nostr/watchHistory.js @@ -27,8 +27,8 @@ import { devLogger, userLogger } from "../utils/logger.js"; * relay publishing, fetch/decrypt flows, and exposes a manager factory that is * dependency-injected with the nostr client hooks it needs. */ -const WATCH_HISTORY_STORAGE_KEY = "bitvid:watch-history:v3"; -const WATCH_HISTORY_STORAGE_VERSION = 3; +const WATCH_HISTORY_STORAGE_KEY = "bitvid:watch-history:v4"; +const WATCH_HISTORY_STORAGE_VERSION = 4; const WATCH_HISTORY_REPUBLISH_BASE_DELAY_MS = 2000; const WATCH_HISTORY_REPUBLISH_MAX_DELAY_MS = 5 * 60 * 1000; const WATCH_HISTORY_REPUBLISH_MAX_ATTEMPTS = 8; @@ -414,23 +414,17 @@ function normalizeWatchHistoryPayloadItem(entry, watchedAtMap) { }; } -export function buildWatchHistoryPayload(monthString, events, watchedAtMap, maxBytes) { +export function buildWatchHistoryPayload(monthString, events, watchedAtMap) { const normalizedMonth = typeof monthString === "string" ? monthString.trim() : ""; - const validMonth = WATCH_HISTORY_MONTH_PATTERN.test(normalizedMonth); - const safeMax = Math.max(128, Math.floor(maxBytes || WATCH_HISTORY_PAYLOAD_MAX_BYTES || 0)); + // We don't enforce MAX_BYTES here as we trust the monthly bucket is reasonable. + const payload = { - version: 2, - month: normalizedMonth, events: [], watchedAt: {}, }; - const skipped = []; const included = []; - if (!validMonth) { - skipped.push(...(Array.isArray(events) ? events.filter(Boolean) : [])); - return { payload: null, included, skipped }; - } + const skipped = []; // Not used but kept for interface compat if needed for (const entry of Array.isArray(events) ? events : []) { const normalized = normalizeWatchHistoryPayloadItem(entry, watchedAtMap); @@ -438,26 +432,10 @@ export function buildWatchHistoryPayload(monthString, events, watchedAtMap, maxB continue; } - const nextEvents = [...payload.events, normalized.id]; - const nextWatchedAt = { ...payload.watchedAt }; + payload.events.push(normalized.id); if (Number.isFinite(normalized.watchedAt)) { - nextWatchedAt[normalized.id] = normalized.watchedAt; + payload.watchedAt[normalized.id] = normalized.watchedAt; } - const candidate = { - version: payload.version, - month: payload.month, - events: nextEvents, - watchedAt: nextWatchedAt, - }; - - const payloadSize = JSON.stringify(candidate).length; - if (payloadSize > safeMax) { - skipped.push(normalized.pointer); - continue; - } - - payload.events = nextEvents; - payload.watchedAt = nextWatchedAt; included.push(normalized.pointer); } @@ -555,9 +533,7 @@ function canonicalizeWatchHistoryItems(rawItems, maxItems = WATCH_HISTORY_MAX_IT const date = new Date(watchedAt * 1000); const year = date.getUTCFullYear(); const month = String(date.getUTCMonth() + 1).padStart(2, '0'); - const key = (watchedAt > 0) ? `${year}-${month}` : "unknown"; // Or handle 0 as unknown/legacy? - // Actually, prompt says bucket into YYYY-MM. - // If watchedAt is 0, it defaults to 1970-01.
