coinosv3.git/tools/feed-media-cache-test.js, branch master

Feed videos before they play: the picture fills the box with only the play button and size (no seek bar or sound button until playing); hovering the cover no longer paints it over with the app's button grey; upright phone clips (stored sideways with a quarter-turn matrix) paint upright, v1 size caches dropped; a clip the probe found HEVC switches to the copy before fetching the original

Browser tests: public relays answered in the page, never reached

2026-10-07T19:02:51Z

A suite run let ~90 throwaway test wallets subscribe and publish on public relays from one home address, and nos.lol and relay.damus.io banned it. tools/puppeteer.js wraps puppeteer-core: every socket to a non-local host gets an in-page stand-in relay (EVENT -> OK, REQ -> EOSE). Tests that read real content launch with { relays: 'read' } (real reads, publishes answered in place); feed-live, chat-layout and cordn-ui launch with { relays: 'live' }. LIVE_RELAYS=read|1|host,... overrides per run. profile-key-qr: measure the QR again if a repaint swapped it out. Co-Authored-By: Claude Opus 5.5

Feed tests: catch up with Articles, Popular as the default feed, timed feed defs and the tint that fades on sight

2026-10-07T15:12:38Z

- feed-media-views: the mode switch has an Articles button now - feed-media-cache: the live watch's since-only subscription isn't part of the crawl - feed-switch-seed: seeded feeds carry their edit time (the feeds sync merge drops one without) - feed-editor-relays: nos.lol is a local stand-in relay, so the test doesn't depend on reaching it - feed-streaming: the stub wallet opens on Following (no remembered feed = Popular); the held picture answers repeat fetches once released; the new-post tint is recorded as it paints (it fades on sight) Co-Authored-By: Claude Opus 5.5

Rebuildable caches move from localStorage to IndexedDB (cache-store.js)

2026-10-07T14:24:33Z

localStorage is ~5M characters per site whatever the device, and a phone had filled it. Profiles, faceless list, reports, follow packs, profile pages, relay lists, the moderation baseline, community directory, link previews, video sizes/probes and search profiles (~3M on that phone) now live in IndexedDB, which shares the site's disk allowance (GBs). cacheStorage keeps localStorage's string API: reads from memory, coalesced write-behind, flushed on hide. Copies migrate on open and are removed once written. Boot waits for it (max 3s) beside the Ark store; caches read at construction re-merge on ready; an early write can't replace the stored copy. A copy an older build writes to localStorage later moves in on first ask. Wallet wipes reach it; private mode stays on localStorage. Read markers, drafts, follows, note threads and sync outboxes stay in localStorage on purpose (cross-tab consistency, early server-rendered seeding). Also asks navigator.storage.persist().

Video frames from bytes, not from a CORS player; pager clips load plainly again

2026-10-03T22:52:38Z

Regression from 6488806: pager clips were loaded crossorigin so their frame could be kept, and on a phone the large clip's slide went black. Some hosts (Primal's R2 bucket) send CORS headers only to a request with an Origin and don't Vary on it, so a copy the browser cached from a plain player load answers a later CORS load without them, and it fails. The same thing made the size probe fail for any clip that had played in the feed. - Pager clips load plainly again; the still under a tap-to-play cover is restored on every return. - The probe (and its HEAD) go past the browser cache (no-store). - A clip's frame is now made from bytes: the opening of the file (index plus about 1 MB, no-store) decoded from a blob and kept as a JPEG — for tiles and as the pager's poster. No CORS player anywhere. Files whose index trails, or hosts whose bytes can't be read, keep the plain player still (shown, not kept). - Kept frames are 480 px wide (were 270) and capped at 600. - Probe failures are stored as failedAt, so earlier failures are asked again at once. - Test: an R2-style host, its clip cached by a plain load first, is still measured and its frame kept (failed before this change).

Video tiles: a frame even when the size check fails; retry it later

2026-10-03T22:32:41Z

Efrat's clip (blossom.primal.net → r2a.primal.net) showed a blank tile on a phone: the 64 KB probe failed there (slow connection), the failure was kept for good, and a tile with a failed probe never tried for a frame. - A failed probe is dated and asked again after an hour (it was kept forever; old 'failed: true' entries are retried). The probe waits 10 s. - A tile whose probe failed still tries for a first frame, giving up and letting go of the file after 8 s. - Primal's CDN lets scripts read the bytes but not Content-Range, so the size was unknown: a HEAD's Content-Length (readable by any page) fills it in. - No size in imeta but a bitrate and duration (Primal posts those): the size is estimated from them. 'dim 1080.0x1920.0' is understood. - A tile with nothing to show is dark, like a video, not a pale gap.

Media views keep their own cache and crawl for media directly

2026-10-03T22:05:52Z

Videos was slow because the grid read from the feed's page of posts: the feed cache holds 30, so after every reload the grid re-crawled the relays, ten posts a step, each post first waiting (up to 8 s) for its avatar, pictures and link cards — none of which the grid shows. - Each feed now keeps a media index (IndexedDB, src/media-cache.js): the posts carrying pictures and those carrying clips, 400 of each, and how far back it has looked. The grid and pager read from it; a reload paints them at once. - The crawl reads older posts straight into the index, 100 at a time, without the readiness wait and without touching the feed's own page; it resumes from where it stopped. The bottom of a feed is looked for again after a day. Curated feeds still page the usual way. - A tile's first frame is kept (a small JPEG in the Cache API, when the host lets its pixels be read) and painted as a picture from then on: in the grid, as the pager's poster and the feed's. - Probe results kept for 2000 clips (was 600). - Forgetting a wallet wipes the index and the frames. tools/feed-media-cache-test.js Co-Authored-By: Claude Opus 5.5 Claude-Session: https://claude.ai/code/session_01ULQZS9MQa6iAsXnrJUD9Du
