A failed connection or token step answered nothing about the channel, yet stamped it: one proxy blip
during an RSS blackout delayed every due channel by a whole window. YouTubeError now names the
endpoint that answered; a failure no endpoint gave, or a spent quota, ends the round and stamps
nothing.
A channel whose uploads playlist also failed was never stamped, so a terminated channel was charged
again on every 20-minute poll instead of once per rss_fallback_hours. An upstream quotaExceeded now
stops the round instead of charging every remaining channel the same refusal.
An INFO line outside a request never reaches log_events, so the fallback's
own summary was invisible in the Server log. Its counts ride on the
sync.rss.failed warning, the one line of a poll the console keeps.
Measured on localdev: 375 of 375 dark channels read, 403 new videos.
YouTube's RSS goes dark per channel for hours (prod 2026-09-18/19: 393 of
396 feeds answered 404 for four hours, sticky per channel, so a retry does
not help), and nothing else read a followed channel's new uploads. A
channel whose feed has not answered for `rss_fallback_hours` (admin knob,
default 2, 0 = off) now gets one page of its uploads playlist through the
Data API (1 unit), at most once per window, yielding to the backfill
reserve. Spend is attributed to its own quota action.
114 exception handlers neither logged nor re-raised. The defect was never that
they are silent — plenty of them should be — it is that their silence said
nothing, so nobody could tell a decision from an oversight. Each one has now been
read. 44 got a line; the other 70 carry `# silent-ok: <why>`.
What the silent ones had been hiding, in the cases that got a line:
- A failed ffprobe sent every HDR file down the 8-bit pipeline, so playback
degraded to a software transcode with nothing saying why; a failed audio probe
collapsed a multi-audio file to one track and the player showed no language
picker; a failed first-PTS probe left subtitles seconds out of sync.
- A subtitle sidecar that existed but would not parse made a PARTIAL track read as
complete, permanently — the viewer loses every cue past the cached window.
- An unreadable crop/trim/cut-list in an edit spec was dropped, so the clip came
out uncropped, untrimmed, or shorter than the one the user built.
- A dropped `max_height` downloaded at best quality against an explicit cap.
- A failed videos.list enrich made every candidate undroppable-from-judgement and
therefore dropped: a working search rendered as "no results".
- An unusable password hash answered as "wrong password", locking the owner out
and telling them they mistyped; a rotated TOKEN_ENCRYPTION_KEY turned every
stored token into "not connected".
- A stored admin setting that would not coerce fell back to the env default while
the settings page went on showing the saved value.
- A one-off InnerTube config failure pinned the whole process to the hard-coded
fallback key, and searches return nothing when that goes stale.
- The HLS sweep reported 0 swept — like a clean run — when it could not list its
own root, leaving every crashed session's segments on disk forever.
Four of them are counted rather than logged per item (dropped cues, dropped cut
list segments, unreclaimed GC files) and reported once per call, because the
alternative is one line per cue over a whole subtitle track.
ruff gains S110 and BLE001. Every blind `except Exception` that remains carries
`# noqa: BLE001 — <why>`, which is the point: catching everything is sometimes
right, and always worth a sentence. plex/sync.py's three best-effort backfill
catches now keep the traceback — a blind catch over a batch that fetches AND
writes could be Plex, the database or our own bug, and `%s` of the exception told
them apart badly. main.py's boot-time log-level read likewise.
logs.event's `code` is positional-only now: `event("x", code=...)` was a TypeError,
and `code` is exactly the word a caller reaches for when the thing that failed has
one of its own.
tests/test_swallowed_exceptions.py is the wider rule ruff cannot see: a handler
that neither logs nor re-raises must say why. Both cases mutation-checked — a
marker removed and a log line removed each fail it, naming the handler.
25 literal names covered 34 modules. plex/client.py, plex/stream.py,
plex/subtitles.py, plex/sync.py and two Plex route modules all called themselves
`siftlode.plex`; downloads/pipeline.py called itself `siftlode.worker`;
routes/channels.py called itself `siftlode.api`. The `logger` column is in every
stored row so E22.6's console can filter on it, and so an operator can pin a level
to one part of the system — neither works when six modules share a name.
`logs.get_logger(__name__)` derives it: app/plex/sync.py -> siftlode.plex.sync.
One name per module, and it cannot drift from the file it sits in.
tests/test_logger_names.py pins the derivation, that everything stays under the
one `siftlode` tree the handler and the tests attach to, and that no module
hand-rolls a name again unless the line says why (`# logger-name-ok: <why>`).
Two do: get_logger's own call, and `siftlode.http`, which is named for the traffic
it carries rather than the module it lives in — it replaced uvicorn's access log
and is what an operator pins when they want request lines and nothing else.
app/scheduler.py called its logger `logger`; every other module calls it `log`.
ruff gains LOG, G, T20, TRY400, TRY401 and S112. Four findings cleared with them:
worker.py logged `str(exc)[:120]` where the traceback was the whole question, and
three prints/f-strings that are deliberate now say so on the line. S110 and BLE001
stay off until S3 — 23 handlers are outstanding and each is a judgement about one
of them; enabling the rules first would just mean 23 blanket noqas.
The explore purge rebuilt followed_channel's two EXISTS clauses inline, so what is polled and what may be deleted could drift; it now uses the predicate, which moved to sync/explore.py. The env validator and sysconfig each folded a choice value on their own; both call config.canonical_choice. The deep-backfill comment no longer calls recent backfill unconditional.
The scheduled RSS poll and recent backfill covered every channel row,
but rows also come from search results, playlist sync and dropped
subscriptions, and nothing deletes them. On prod 582 of 979 polled
channels had no follower, three of them dead feeds answering 404 on
every poll. Both jobs now take subscribed or explored channels only,
and the scheduler card counts the same set. As a deliberate trade-off,
the shared Library no longer receives new uploads from channels nobody
follows.
The log now has a stored, queryable copy for the diagnostics console:
every WARNING and above plus the request line of every request, kept
for log_retention_days (default 7, no "forever") and pruned hourly by
the new log_gc job.
Rows are built on the logging thread from the same redacted fields as
the stdout line, queued without blocking and written in batches by one
background thread on its own connection. A full queue or a failed write
drops and reports instead of retrying. Flood control keeps 30 of any
one message per minute plus a count of the rest; anonymous request
lines are capped at 60 a minute per client, and the client address is
never stored. Deleting an account deletes its stored events.
Measured on prod first: a YouTube RSS outage wrote 11k warnings in four
hours, one per channel per poll. The poll now writes one warning with
per-reason counts and a few examples, and a failure on our side gets
one traceback per poll instead of one per channel.
Addresses the code-review findings on the immediate full-history change:
- Extract quota.backfill_reserve_reached(): the remaining/reserve compare was
open-coded at seven sites (recent/deep/immediate backfill, explore, rolling
revalidation, and the new per-page guard). It reads in its OWN short-lived
session (like record_usage/log_action), so a per-page guard no longer holds
the caller's transaction open across the YouTube fetch that follows — the
400-page immediate run no longer pins a pooled connection idle-in-transaction
through each network round-trip. Migrated all call sites; dropped the now-dead
sysconfig imports in channels.py and maintenance.py.
- Simplify the deep-backfill loop: channel.backfill_done = not page_token (done
is False on entry) plus one break, replacing the doubled `if not page_token`.
- Tests patch the backfill_reserve_reached seam directly instead of mocking
remaining_today internals, removing the fragile dead-value budget iterator.
Full backend suite green; ruff clean.
The user-triggered "get full history" (backfill_channel_now) capped at
max_pages=60 = 3000 videos. A channel just over that (BBC Earth: 3403
uploads = 69 pages) stopped one page short, so its tail dribbled in over
the scheduler's paced 10-minute ticks (250 videos/tick) and the button
spinner looked stuck for ~18 minutes with no visible progress.
- Raise the immediate cap to max_pages=400 (20 000 videos) so any
realistic channel completes in the single background run.
- Make a high cap safe: backfill_channel_deep now re-checks the shared
quota before each page and yields at the backfill reserve (previously
quota was checked once by the caller before the whole run), and commits
the advanced cursor after every page so a restart resumes instead of
re-fetching — and re-charging quota for — pages already stored.
- Channel page: while loading, the button shows the live stored/total
count and a tooltip explaining the tail finishes in the background, so a
very large channel's paced remainder reads as progress, not a hang.
Adds deep-backfill paging tests (per-page cursor commit + resume, and the
per-page quota yield).
- Make the immediate-backfill guard SYMMETRIC: run_deep_backfill now also
registers the channel it pages in _backfill_in_progress, so it and
backfill_channel_now mutually exclude per-channel and never advance the
same cursor concurrently (whichever started first). The interactive cap
moves to a separate _immediate_running counter so the scheduler's channels
don't false-trip it.
- Attribute the immediate backfill's spend: wrap it in
quota.attribute(user_id, VIDEOS_BACKFILL_FULL) (route passes user.id), so
it shows under the user's full-backfill action, not the OTHER/system bucket.
- Tests: the update_channel->background-task wiring + the demo guard
(scheduled for a real user, NOT for demo); distinct N/S/L counts (2 short
+ 1 live) so a short/live swap fails; extracted channelDetailPollMs with a
pure unit test of the poll-or-stop predicate.
- a11y: role="img" on the fully-synced charm so screen readers announce it.
- list_channels no longer computes the Normal/Shorts/Live aggregation the
frontend stopped reading when R14 dropped the N/S/L table column; the dead
ManagedChannel.count_* fields are gone too.
- Immediate "get full history" backfill now coordinates with the paced
scheduler via a small in-flight set: capped at 2 concurrent + per-channel
dedup, and run_deep_backfill skips a channel an immediate backfill owns —
killing the cursor race and bounding the quota-drain burst, without losing
the speed win.
- Add test_channel_backfill.py: the channelDetail N/S/L counts + the guard's
no-op / cap / scheduler-skip behaviour.
- Inline the syncedChannels useMemo (its dep is a fresh array each render, so
it never cached); fix the stale "~2-min ticks" comment (it's 10 minutes).
Clicking "get full history" now kicks an immediate background deep
backfill of that one channel (backfill_channel_now: own session, up to
~3000 videos in one pass, quota-guarded) instead of waiting for the
scheduler's paced 10-minute ticks (5 pages/channel/tick). The request
returns instantly and the channel page's live poll shows the count fill
in seconds. A very large channel's tail still falls to the scheduler
(deep_requested stays set).
The worst one was, again, the previous round's own fix.
- Round 7 stopped awaiting the HLS sweep so startup could serve immediately — which
also made it run CONCURRENTLY with playback, and `sweep_orphans` snapshotted the
live-session set BEFORE listing the root and rmtree'd outside the lock. Since
`start_session` reuses a directory path for the same (key, offset, tag), a stale
name can become a live session at any moment. Two guards now: nothing whose mtime
is newer than this process's start is ever deleted, and the live check + rmtree
happen together under the lock, one directory at a time.
- The sweep task is awaited after cancel, so shutdown can't leave it pending.
- `_rate_limiter` used a truthiness test on its timestamp, so a `now()` of exactly
0.0 read as "never ran" — unreachable in production, but `now` exists to be
injected and a test clock starting at 0 is the obvious choice.
- The RSS total-outage error now carries the first underlying error: "all N channels
failed" is also what ONE dead feed id looks like on a small instance, and a red
card the user can't act on is its own kind of dishonest.
- The WebKit fullscreen handling moved into `lib/fullscreen` and PlexPlayer uses it
too — it had the same unprefixed-only reads in three places, including an Escape
branch that would have closed the whole player instead of leaving fullscreen.
- The `--max` CSS comment claimed `inset: 0` did the sizing; Tailwind's `w-full` is
still on the element and wins. Comment now states the real mechanism.
Verified in real Chrome (the pane can't composite or do native fullscreen):
- F fills the 1920x889 viewport; the exit pill renders top-right on the letterbox
band and overlaps NO YouTube control — the collision this round suspected does not
reproduce in this embed (its own buttons sit bottom-left / bottom-right).
- Four real ArrowDown presses while maximised: persisted volume 100 -> 80, with the
level flash visible on screen.
- A real click on the exit pill un-maximises and returns focus to the card.
- lib/fullscreen driven from a real click: enter (innerHeight 889 -> 1024), the
change listener fires exactly once per transition, exit returns to 889.
Backend suite 150 -> 158; the new sweep tests are mutation-checked, and they read
their cutoff from the filesystem rather than a clock (the container VM and the
bind-mounted host disagree by enough to make a clock-based assertion flaky).
Five of them sit where round 6 turned F from a Fullscreen API call into a CSS
maximise: the guards around it still asked `isFullscreen`, which that pivot made
permanently false.
- Arrow-key volume was dead in the maximised view: the scroll-deference checked
only `isFullscreenRef`, so the (now hidden but still scrollable) card kept
swallowing Up/Down. Both flags now count as "the video fills the screen".
Measured: 87px of scroll room on the focused card, ArrowDown moves 80 -> 75
and scrolls nothing.
- The maximised view had no way out once the pointer touched the video. Reaching
YouTube's controls means clicking into the cross-origin iframe, which takes
keyboard focus with it, and the re-arm paths (stage mouseleave, window focus)
need the pointer to leave the browser entirely while the stage fills it. So
the exit now lives on screen, in our DOM: a button that un-maximises AND pulls
focus back, re-arming every shortcut.
- WebKit fires only `webkitfullscreenchange`/`webkitFullscreenElement`, so on
Safari/iPadOS YouTube's own fullscreen never registered — no overlay yield, no
focus reclaim. One `fullscreenEl()` reader, both event spellings.
- The stage claimed `z-index: 9999`, the glass tuner's reserved level, for a job
that only needs to beat the modal chrome it is nested in (its siblings top out
at z-menu). Dropped to rail-level; nothing escapes the modal's stacking
context either way.
- `inset: 0` already sizes a fixed layer — the inherited `100vw`/`100vh`
over-constrained it, which is how a classic scrollbar gets a horizontal
overflow and a mobile URL bar hides the bottom edge (YouTube's control bar).
- The shortcut hint still promised "F: fullscreen" in both locales.
Backend, both "the fix stopped one layer short":
- The startup HLS sweep was awaited inside lifespan, so uvicorn still served
nothing until it finished — a thread doesn't help when nothing is listening
yet. Fire-and-forget task instead, cancelled on shutdown. Measured with 200
planted segments: "Application startup complete" now precedes "swept 1".
- An RSS poll where every channel failed returned normally, so the scheduler
recorded `ok` with the outage buried in the summary string. `failed == total`
now raises: a run that reached nothing is a failed run.
Suites: backend 147 -> 150.
- run_ffmpeg stops the process from ONE exit path (`except BaseException`), so
an exception out of on_progress (a DB write) can no longer orphan a live
ffmpeg after a 10s join on its pipes; _stop is now a no-op on a dead process
- both run_ffmpeg callbacks are throttled to ~1s (they were a DB round-trip per
output line: ~10^5 queries on a long re-encode), mirroring the download hook
- volume arithmetic extracted to lib/playerVolume with unit tests; a corrupt
level now falls back to the LAST GOOD one instead of full blast, and the
sanitising happens where the stored value enters
- RSS is back to two except clauses (the shared tail already sits after the try)
- new tests: callback-exception cleanup, the two throttles; the fake Popen grew
poll() and its wait count is now asserted
Mutation-checked: each new group goes red when its fix is reverted.
- Feed memoizes onClose (like Playlists already did): the inline closure re-ran
PlayerModal's keydown effect on every Feed render, which since the debounce
landed also flushed the volume write and re-stole focus
- the player reads its volume with readAccountMerged again — a partial stored
object made the level undefined -> NaN -> a persisted null; applyVolume also
refuses a non-finite level outright
- that read moved into a lazy useState initializer (was running per render)
- the two RSS except branches share one tail, so a counter can't drift again
- run_ffmpeg tests cover the SIGTERM->SIGKILL escalation and the lingering-
process path; dropped an assertion that only restated the fixture
- storage.ts documents the actual { volume } shape (0 IS muted)
- the sweep guard anchors the rating_key to digits: the round-2 widening had
degenerated to "anything ending in _<digits>" (backup_2024, release_10)
- RSS counts apply-side failures too, so a read-only database no longer reports
a wholly failed poll as "ok — new=0, failed=0"
- the player reads/writes its volume directly (readAccount/writeAccount): the
persisted-object hook rendered nothing and cost a second write per settle
- new tests: the sweep guard's accept/reject table, and run_ffmpeg's threading
(drain, cancel while silent, stall watchdog, stderr tail on a nonzero exit)
- the breaker sentinel is checked one way (isinstance) at all four sites
- run_rss_poll is typed dict[str, int]
All three new test groups were mutation-checked: reverting each fix turns them
red (or, for the cancel/stall pair, hangs — which is the bug itself).
- the volume keys no longer defer to a scrollable card while in fullscreen
(mirrored into a ref: the keydown handler is bound once and state would be stale)
- the debounced volume flush writes straight to storage; persisting inside a
setState updater is not guaranteed to run for an unmounting component
- the HLS sweep also matches the original {key}_{start} directory naming, which
is what the oldest leftovers on disk actually use
- run_rss_poll returns {new, failed} so an egress outage stops rendering as
"ok — 0" in the scheduler card and the audit log; /api/sync/rss reports it too
- drop the unused poll_rss_channel (it silently gained a new exception)
- _Breaker.run is generic, so a call site keeps its item-id type
- test helper instead of the generator-throw idiom
- never prune subscriptions on an empty fetch: one anomalous empty-but-200
response wiped every subscription (and its deep_requested flag) in one run
- push_playlist: stop after 5 consecutive write failures — a quota-dead or
scope-revoked account otherwise burns 50 units per remaining item
- RSS: raise RssError instead of returning [] on a transport/HTTP failure, so a
failed poll no longer stamps last_rss_at and a 404 feed stops looking healthy
- worker: exit when the schema never appears instead of "continuing" into a
crash one call later
- Extract runner.token_users(db): the "all users with a stored refresh token"
query was spelled 3× (get_service_user, run_subscription_resync,
sync_all_playlists). get_service_user now reuses it ([0]); sync_all_playlists
imports it from runner (no cycle — runner doesn't import playlists); the now-
unused OAuthToken import is dropped there.
- scheduler.py: _job("rss_poll", lambda db: run_rss_poll(db)) → _job("rss_poll",
run_rss_poll) — the lambda was dead indirection; all sibling jobs pass the
callable directly and _job calls fn(db).
Behavior-neutral. ruff clean, localdev boots, re-review clean.
Replace the leftover 'subfeed' name across logger names + log_config,
frontend localStorage keys, Postgres user/db/volume defaults in the
compose files, .env.example, config.py, backup/restore scripts and the
README. Pure rename; no behavioural change. localStorage keys move from
subfeed.* to siftlode.* (one-time UI-state reset is acceptable).
Register 8 more keys in the sysconfig registry (quota daily budget + backfill
reserve, recent-backfill window, shorts-probe params, enrich/autotag batch sizes)
and route their reads through the DB-override-or-env resolver at every call site
(quota.py, sync/runner.py, sync/videos.py, sync/autotag.py, sync/maintenance.py,
routes/scheduler.py). All read sites already had a db session in scope. Reads are
read-through (no cache), matching app.state; admin can tune them live, no redeploy.
Every background job now reports progress, so the dashboard can show a live
bar for any run (not only enrich/backfill/shorts/maintenance): rss_poll and
subscriptions (runner), autotag, and playlist_sync gained progress.report
calls over their loops.
RSS polling now fetches the channel feeds concurrently (16 workers) instead
of one-at-a-time — a slow/unreachable feed no longer blocks the rest, cutting
a full poll of the catalogue from minutes to seconds. Feed fetches are
network-bound and run in the pool; DB inserts stay on the session's thread
(SQLAlchemy sessions aren't thread-safe), applied as each fetch completes.
Split the DB-write half of poll_rss_channel into apply_rss_feed so the fetch
and apply phases compose cleanly.
Add per-job "Run now" buttons and a "Start all now" button to the admin Scheduler
dashboard (admin-gated endpoints). Triggers run the job in a background thread
independent of its interval, refusing a concurrent run (409). While running, the
long jobs (maintenance, enrich, backfill, shorts) report live progress through a
decoupled contextvar sink, shown as a progress bar on the job row via the existing
4s poll. A manually-triggered run posts a completion notification to the triggering
admin's inbox (scheduled runs stay silent to avoid spam); the inbox renders the
"scheduler" type trilingually from type+data. While here, give the maintenance job
its missing dashboard label/description in all three languages.
enrich_pending only touches enriched_at IS NULL, so a video first seen
while live was stamped live + duration-null and never revisited — staying
'live' with no duration forever after the broadcast ended. Add refresh_live
(run after each enrich pass) that re-fetches anything still live/upcoming,
plus just-ended was_live videos that haven't got their duration yet, until
they settle. Cheap: videos.list is 1 unit per 50 ids.
A channel whose stored uploads already meet or exceed YouTube's advertised
video_count holds its whole history, but backfill_done could stay false forever
when the deep cursor never reached the end (e.g. a small channel that was never
deep-requested, so the demand-driven deep job never ran). Such channels nagged
as 'needs full history' despite having every video. Add reconcile_full_history()
(idempotent, no quota) and run it at the end of each recent/deep backfill cycle
so backfill_done self-heals.
Per-user opt-in to full-history (deep) backfill so a new user's unique
channels no longer trigger a big shared-quota burst.
- migration 0007: Subscription.deep_requested (default false); seed admins'
existing subscriptions to preserve today's global-backfill behaviour
- run_deep_backfill is now demand-driven: only channels at least one user has
requested are deep-backfilled; recent backfill stays unconditional (cheap)
- estimate_deep_backfill ETA helper (quota-bound) surfaced in /api/sync/my-status
- POST /api/sync/deep-all to opt all my channels in; PATCH channels accepts
deep_requested
- UI: per-channel Full history toggle, Backfill everything action, deep
progress + ETA in Channels header and Settings - Sync
- uvicorn --log-config (log_config.json): timestamped formatters for uvicorn
access/error and the app's own "subfeed" loggers (ms precision)
- Log key activity: startup/shutdown, login/denied, token refresh, YouTube API
errors, subscription imports, sync pause/resume
- Background sync jobs no longer swallow errors silently — failures in RSS poll,
backfill, enrichment, autotag and resync are logged with tracebacks
- Language detection: classify one cleaned+concatenated blob (strip emoji,
@mentions, #tags, numbers, punctuation); fixes caps/emoji-heavy channels
(e.g. Nessaj -> Hungarian, no more bogus Chinese/Korean)
- Feed now joins the user's subscriptions, so unsubscribing on YouTube removes a
channel from the feed; periodic subscription re-sync job picks up changes
- Watched/Saved/Hidden views ignore the Shorts/live default-hiding so the full
set is visible (fixes hidden videos missing from the Hidden view)
- Persist feed filters + search across reloads (localStorage)
- 3D polish: cards lift with shadow on hover; chips/buttons get depth and a
press effect; undo toast lasts longer
- Shorts: confirm via youtube.com/shorts/<id> probe (SOCS cookie bypasses the
consent redirect) instead of a 60s heuristic; concurrent probing, shorts_probed
flag, scheduled refinement (migration 0005)
- Search: match title + channel name only (descriptions caused noisy results)
- Faceted tag filtering: AND across categories (language AND topic narrows),
OR within a category; any/all toggle applies to topics
- Language detection: majority vote over individual titles (fixes misdetections
like multipoleguy -> English; drops bogus Polish/Romanian)
- Login: drop forced consent so returning sign-in is quick (select_account)
- Feed cards: clickable channel name (opens channel), persistent saved badge,
undo toast on hide, Hidden view to restore; tag chips show counts in tooltip
- Free per-channel RSS reader for quota-less fresh-video detection
- Recent-first backfill (configurable: 100 videos / 1 year) plus resumable deep
backfill from the uploads playlist
- Enrichment via videos.list: duration, view/like counts, category, topics,
language, Shorts heuristic and livestream/premiere classification
- Reusable sync runners + APScheduler jobs (rss / enrich / backfill), all
quota-aware with a reserve so backfill never starves fresh enrichment
- Manual triggers: POST /api/sync/{rss,backfill,enrich}
- Exact insert counting via RETURNING with in-batch de-duplication
