From 214452e6452f38132d5a8f27e10ef85b82b27ebb Mon Sep 17 00:00:00 2001 From: Dave Rolle Date: Thu, 11 Jun 2026 01:22:34 +0200 Subject: [PATCH 01/79] Fix outage-class error handling (baseline review issues) The polling loop previously died permanently on any escaped handler error (telegraf's default handler rethrows), and telegraf's 90s handlerTimeout guaranteed exactly that on slow downloads - the likely cause of the historical crash. Now: - bot.catch logs and keeps polling (sets exitCode for parity); handlerTimeout raised above the worst-case handler - launch() crash exits the process so docker restarts it instead of leaving a zombie; start() resolves via onLaunch + a bounded wait for telegraf's polling field (instead of the unbounded private-field spin) - LogMessage: debounce-timer flush catches its own errors; failed initial replies are logged and retried on the next flush - handlers: root cause logged before (and independent of) the user-notification attempt; callback handler has a last-resort catch; non-Error throws render sensibly - getInfo: corrupt cache entries (incl. symlinked canonical targets) are discarded and re-scraped; cache writes are awaited but can no longer fail a successful scrape Each behavior has a test; suite is 160 green with thresholds met. Closes #6's crash-amplifier portion; remaining baseline findings tracked in #4-#10.

From cf60d4aa371ba24adf77f97cbbaeeaedf53b31d4 Mon Sep 17 00:00:00 2001 From: Dave Rolle Date: Sat, 13 Jun 2026 00:28:18 +0200 Subject: [PATCH 15/79] Durable job queue: parallel downloads that survive restarts Handlers now only persist a job file (so the telegram ack stops being the durability mechanism) and a worker pool processes up to 3 jobs in parallel, recovering queued work on boot. yt-dlp concurrency is capped at the execYtdlp layer so inline queries count against it too. LogMessage/download-video/handlers run off (telegram, me, job fields) instead of telegraf ctx. handlerTimeout drops to 5 minutes; an inline query exceeding it is logged and left to finish detached, while a timeout on the enqueue-only handlers still flags the process.

charset=UTF-8 Content-Transfer-Encoding: 8bit QA found restart-mid-send delivers the video twice: the job file outlives a completed send, so recovery replays it. Jobs are now renamed to .sending right before the telegram send and recovery drops marked jobs ā€” downloads stay at-least-once, sends become at-most-once. limit() handed its slot non-atomically (a microtask-window arrival could exceed the cap); the releaser now passes the slot to the waiter directly. SIGTERM stops the queue from starting new jobs, and the e2e harness drains in-flight jobs before deregistering its mock API.

From ab383b3c465bdb779c567e2f2ff7a1c398fcf5e3 Mon Sep 17 00:00:00 2001 From: Dave Rolle Date: Sat, 13 Jun 2026 19:21:57 +0200 Subject: [PATCH 17/79] Resolve open decisions: at-least-once queue, store unification, clean exit Settled the PR's open questions: - Send delivery is at-least-once: recovery re-runs jobs (reverting the at-most-once .sending-drop). Duplicates are minimized by prompt unlink and a 30s compose stop grace so in-flight sends finish before SIGKILL. - An unexpected processor throw retries up to 3 times (attempts counter in the job file), then drops, so a deterministic bug can't crash-loop; a failed retry-write drops cleanly rather than orphaning the job. - bot.catch no longer sets process.exitCode on contained errors, so a later graceful shutdown isn't reported as failed. - The confirmation store is unified: parked files are confirmed-job shaped, and confirming is one atomic rename into the queue (adoptJob) instead of take-then-enqueue with a restore-on-failure dance.

The marker is consumed before check.sh and expires after 5 min, so a stale or abandoned one can't approve an unrelated commit. Because check.sh now gates every commit, the flaky 'recovers persisted jobs in FIFO order' test had to go: run() lazily reads each job file before calling the processor, so at concurrency 3 two recovered jobs race and completion order isn't deterministic. The test now forces concurrency 1 (sequential), via a test-only resetJobQueue override, so processor-call order equals the dequeue order it means to assert.

Reserve before the rename, mirroring enqueueJob, and roll back `known` if the rename throws. Give ids a fixed-width monotonic counter between the timestamp and the uuid so same-millisecond enqueues keep submission order through the recovery name-sort (a random uuid tail reordered them). Tested. Quiet the run() "unreadable job" log for ENOENT: a missing file is a consumed job, not corruption (Bun throws SyntaxError, code undefined, for malformed JSON, so real corruption still logs). No deterministic test pins the adoptJob race itself: reproducing it needs an injected seam between the rename syscall and the JS continuation, and a non-deterministic test is a false guard (verified: the obvious Promise.all test passes with the fix reverted). The intent comment carries the invariant instead.

From ba43a8bb94c0dbcd0518c1889f0cefbf936ae123 Mon Sep 17 00:00:00 2001 From: Dave Rolle Date: Mon, 15 Jun 2026 07:39:03 +0200 Subject: [PATCH 30/79] Self-update yt-dlp atomically; poll every 5 min MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit yt-dlp's zip-variant `--update` rewrites the binary in place, so a download exec'ing it mid-rewrite could get a corrupt file. Update a copy and atomically rename it in instead ā€” running execs keep the old inode, new execs see old-or-new, never a partial. Drop the interval 24hā†’5min so a broken extractor is fixed within minutes; each poll is one unauthenticated GitHub API call, well under 60/hr/IP. Single-flight so the boot call and the timer can't overlap. Skip the swap only when yt-dlp reports it's current AND the copy's size+mtime didn't move ā€” biased toward swapping so a real update is never silently dropped.

Both cleanup paths ā€” the prompt-send failure (requestConfirmation's catch) and the requester's cancel ā€” unlinked that file but left the memo. A retry or a re-request of the same URL then replayed the stale 'downloaded' verdict without re-downloading, and sendVideo threw on the now-missing file; since that error isn't permanent, the job crash-looped to MAX_ATTEMPTS and the video was lost for the process lifetime. Route both cleanup paths through a shared discardConfirmedDownload helper that unlinks the file and drops the memo entry together, so neither site can drift out of lockstep again. sendVideo's own post-send unlink stays outside the helper: it writes the .id file in the same breath, so isDownloaded remains truthful and the memo verdict is still valid.

That kept spawning races and durability gaps we patched one at a time (the take/adopt race, the non-atomic retry-persist, double-queue windows). Replace it with one embedded SQLite database (bun:sqlite ā€” built into Bun, no dependency, no separate process, synchronous). A new src/db.ts owns the connection, the WAL pragmas, a versioned migration, a tx() helper, and a test-only resetDb(). job-queue.ts and pending-downloads.ts become thin table wrappers; the in-memory pump/concurrency/backoff layer is kept verbatim on top. What the transaction dissolves: - confirm vs cancel: both DELETE ā€¦ RETURNING the same pending row, so exactly one wins ā€” no rename/unlink race. - retry-persist: a single UPDATE replaces the non-atomic in-place file rewrite. - FIFO + recovery: rowid is the submission order; recovery is SELECT ā€¦ ORDER BY id; at-least-once is a row that outlives a crash. adoptJob now takes a pending id (not a file path) and does the delete-pending + insert-job move in one transaction. isNotFound moves to src/fs-utils.ts (the blob bytes and yt-dlp temp files still live on disk). The blobs / video_info tables and blob_key columns are created now but unused ā€” the content-addressed blob store that fills them is the next phase. Tests run against a real DB (SQLite is ours, so it isn't mocked); resetDb() replaces the per-test directory wipes, and the e2e seeds a row instead of a job file.

Title/URL-derived names plus no shared ownership are what made the cross-job unlink races possible. Replace all three: - A content-addressed blob store (src/blob-store.ts): a blob's key is a hash of yt-dlp's stable video identity (extractor:id:format), known before download, so the "already have it" short-circuit survives. Bytes live at /storage/blobs/.; downloadVideo renames yt-dlp's output there and records a `blobs` row. The file_id moves into that row (the `.id` file is gone); the info cache moves into a `video_info` table (the symlinks are gone). - Refcounted GC (releaseBlob): the bytes are unlinked only when no parked confirmation still references the blob_key and it has no file_id ā€” the reference check and the row delete are one transaction, so two concurrent releases can't both unlink. This dissolves the shared-blob race at the root. - Confirmed jobs self-heal: processConfirmedJob now always calls downloadVideo (a no-op when the blob is present, a re-fetch when it was GC'd), so a blob a concurrent release dropped is re-downloaded instead of failing the send. discardDownload (release the blob + invalidate the in-process memo) runs on every abandoned-work path: a failed confirmation prompt, a cancel, a terminal job failure, and a failed inline query. The Telegram file_id is now a single column rather than per-bot-identity ā€” correct for the single-bot deployment (dev and prod aren't meant to share the DB).

charset=UTF-8 Content-Transfer-Encoding: 8bit Content-addressing the blob store removed the last use of the bot username: it only ever named the per-bot `.id` file_id cache, which is now a DB column. So `me` is dead weight threaded from bot.ts through processJob into downloadVideo/sendVideo. Remove it from those signatures (and their memo-key tuples), from processJob/processUrlJob/processConfirmedJob, and from the inline handler. The bot.ts processor closure no longer reaches for bot.botInfo!.username, so the stale "recovered jobs need botInfo for file naming" comment goes too (the bounded polling-wait stays ā€” it's there so SIGINT's bot.stop() doesn't throw before telegraf sets its polling field).

fix audit findings MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The whole-PR review surfaced a blob-GC race ā€” a job's terminal failure could unlink bytes a concurrent job for the same video was mid-upload on ā€” plus a few smaller edge bugs. Rather than refcount in-flight jobs, serialize them: withBlobLock(info, fn) is a per-content-key FIFO async lock, and every operation that materializes, sends, or deletes a blob's bytes (both job processors, the inline handler, and cancel's cleanup) runs under it. Concurrent same-video work takes turns: the second reuses the first's cached file_id, or re-downloads cleanly if the first failed and discarded. The download/send/release primitives stay lock-free; only those entry points acquire it (via releaseAbandoned for the out-of-lock release paths), so there is no reentrancy. Also from the audit: - sendVideo now releases an over-size video's blob ā€” it returned without sending, leaking a multi-GB file and its row forever. discardDownload moved into download-video.ts so sendVideo can call it. - getInfo skips the DB cache for a verbose request, so /verbose actually re-scrapes and streams yt-dlp output instead of silently returning a cached row. - probeDuration returns undefined without spawning ffprobe when the file is gone (an already-uploaded blob), dropping a spurious error log. - Removed the obsolete `mutations` test-seam; the durability tests now drive real DB write failures (RAISE(FAIL) triggers) and a real EISDIR unlink rather than spying owned code. - Refreshed stale filesystem-era comments left by the SQLite rewrite. Test-run hardening (the CPU incident): check.sh and CLAUDE.md wrap the containerized `bun test` in `timeout -k 30 300`, so a hung/non-exiting run self-kills and `--rm` cleans up instead of orphaning a 100%-CPU container.

The initial migration is unreleased (prod creates the DB fresh at merge), so it's finalized in place. - Remove the sendVideo memoize. withBlobLock serializes concurrent sends of the same video and blobs.file_id handles reuse, so the memo could only ever cache a stale result ā€” e.g. a repeated inline query of an over-size video re-cached its `undefined` and needlessly re-downloaded the bytes. - Reject an over-size video for an inline query before downloading it: inline is for small clips, and a >2GB video can't be sent anyway. New tooLargeToSend() gates on the scraped size up front; sendVideo still gates on the real on-disk size after download (for when the estimate is missing/wrong). - Comments: the refcount is a release-guard, not a GC; refresh stale filesystem-era test comments left by the SQLite rewrite.

charset=UTF-8 Content-Transfer-Encoding: 8bit The commit gate's marker was content-free: `touch .commit-approved` let any `git commit` through once /commit had run at some point, so "fix every review finding" relied on discipline ā€” the recurring failure mode. Make the approval deterministic and un-inheritable: - stage-id.sh: a content-bound id for the staged snapshot = HEAD + the staged tree SHA (git's own content hash of the index). Returns nonzero if the index can't be hashed (unmerged), so callers fail closed instead of minting a degraded value. - review-approve.sh: mints the approval, run by /commit's new review-attestation step ONLY after a fresh agent finds the staged change clean. Computes the id before writing, so a hashing failure leaves no marker. - commit-gate.sh: allows a commit only with a fresh approval whose hash matches the EXACT staged snapshot. A direct commit (no marker), an inherited/stale approval, or any re-stage after the mint all block. It does not claim to prove a review ran ā€” it makes an omitted review a deliberate, visible bypass. - pr-approve.sh / pr-gate.sh: the same for /pr's merge gate ā€” pr-gate.sh stamps all-pr-skill-steps-passed only with a whole-PR approval bound to HEAD, instead of a raw `gh api` call. - /commit and /pr SKILLs: a fresh attestation agent re-reviews the final change and mints the approval (you never mint it yourself); the gate is run, not hand-stamped. Every block/allow path was tested directly, including the unmerged-index fail-closed path; this commit itself went through the new gate.

tighten one comment MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Content-addressing put the format into the blob path: the sha is sha256(extractor:id:format) and the mock's file_id is hash(blob path), so a yt-dlp format-selection shift would spuriously break the download/cache snapshots ā€” the very drift scrub() exists to absorb. Extend scrub to normalize the blob sha (/storage/blobs/<sha>) and the derived file_id (<file_id>); the download-vs-cache snapshot shapes stay distinct, so the cache assertion holds. Regenerate accordingly. Also tighten the inline-query comment to drop a clause that restated `?.[0]`.
