- commands: /bot_dict dumped the whole chat state to any member of the chat
and could exceed Telegram's 4096-char message limit (the send then failed
and bubbled up as a handler error). It is now admin-only and capped at
MAX_DEBUG_DUMP_CHARS; README, README.en and the /help description updated.
- send: the edit-before-forward template buttons were built from a HashMap
walk, so their order changed between prompts. Now sorted by name.
- link_cache: an unparseable payload (older schema) was reported as a miss
but left in place, re-failing the parse on every later hit; the row is
dropped on read.
- handlers: a link handed to the URL workers after the channel closed
(shutdown) was discarded silently; it is now logged.
- rate_limit: LIMITERS kept one bucket per chat that ever sent media,
forever. The periodic sweep now drops buckets that are idle (refilled to
capacity) and not held by an in-flight sender; acquire's refill was
factored into a shared helper used by the idle check.
Tests: +3 (corrupted row dropped, sorted markup, idle-bucket pruning); the
cache one was verified to fail before the fix. fmt/clippy clean, 55 + 69.
- send: the PHOTO_INVALID_DIMENSIONS marker never matched (the description is
lower-cased, the marker was not), so oversized photos sent by URL were
classified Permanent instead of taking the download-and-downscale fallback.
- inline: the debounce state was one global slot, so a second user's query
cancelled the first user's pending answer entirely; it is now per user.
- state: prune_expired wrote back a stale snapshot without the per-chat lock,
clobbering a concurrent update() (lost edit-message record -> "Expired");
it now re-reads and prunes under the same lock update() uses.
- send/queue: a task dead-lettered on retry exhaustion kept its keep-alive
temp media (ugoira MP4) alive until process exit; dead_letter_notify now
releases it, and enqueue_retry releases when the enqueue itself fails.
Also folds the duplicated retry enqueue in post_send_actions into
send::enqueue_retry (single clock source, single place that releases).
Tests: +6 (marker, per-user debounce x3, keep-alive release, prune contract
x2); the marker and keep-alive cases were verified to fail before the fix.
cargo fmt/clippy clean, 52 + 69 tests pass.
Fourth site adapter: POST /api/notes/show, renote-aware caption and
media normalization, DriveFile type → Illustration/Animated/Video.
Empty thumbnailUrl strings filtered out in thumbnail_for.
- updated_sequence_task: clone the Task and mutate the two fields
instead of rebuilding all 12 by hand (-22 lines; new fields no
longer need a sync here)
- unify unix_now with db::now_f64 (unix_now() = now_f64() as i64),
moved to db.rs next to its clock source
- classify_to_send_error takes the MediaFetchFailure label, folding
the duplicated inline match in send_batch_via_upload (-8 lines)
- photo.rs: chunks_exact(4)/(2) -> as_chunks::<N>().0
(chunks_exact_to_as_chunks, the new lint prefers the
compile-time-checked slice split)
- send.rs: box the Task inside SendError so the error fits the
result_large_err limit (Task is ~400 bytes; the error now moves
through Result as a pointer); unbox with *task at the two
enqueue_retry call sites (handlers/urls.rs, handlers/callback.rs)
cargo clippy --workspace --all-targets is now warning-free; the
remaining proc-macro-error2 future-incompat note is upstream
(teloxide -> aquamarine) and unfixable locally. Full test suite passes.
1.3.0 → 1.4.0: new features (DATA_DIR config, /test blockquote HTML
report) plus the twitter entity-decode, post-send-actions and queue
lease-heartbeat fixes.
Replaces the strip-tags plain-text rendering: the /test reply is now an
HTML message (reply_html helper with ParseMode::Html). Raw fields (url,
source_url, title, author_url, media urls) are escaped, the pre-escaped
render fields are embedded as-is, and the caption is wrapped in
<blockquote>...</blockquote> so the report shows it exactly as it will
render in the sent media caption — escaped text and clickable links
included, no literal &/</> and no raw markup.
The DB file was hardcoded to CWD-relative data/task_queue.db — a footgun
for systemd/cron deployments and a confusing startup failure when the
data/ dir did not exist (SQLite never creates parent dirs).
db_path() now reads DATA_DIR (default data, CWD-relative, unchanged for
local runs and the docker-compose ./data mount) and creates the
directory automatically. README/README.en.md env tables and AGENTS.md
document the new variable.
Runs actions-rust-lang/audit after the offline tests in the test job: a
crate in Cargo.lock with an unfixed security advisory fails the build.
Verified locally against the current lockfile (0 vulnerabilities; the 3
warnings — unmaintained dotenv/proc-macro-error2 and transitive anyhow
unsoundness — do not fail by default).
AGENTS.md claimed user-facing bot strings are Chinese, but every
reply/send_message string in the code is English (Hello!, Send failed,
No media found, Reply to edit message, ...). README stays Chinese;
update both the overview line and the convention line to state the
actual split.
The report's caption line still showed the raw HTML markup
(<a href="...">...</a>). strip_html_tags now drops the tags (keeping
the visible text; the links are already reported via source_url /
author_url) and the remaining entity-encoded text is decoded — the
strip runs on the escaped caption so a tweet text like >^ω^< survives
instead of being eaten as markup. Custom-format captions contain no
tags and pass through unchanged.
The lease was set once to now + LOCK_TTL_SECONDS (120 s) with no
renewal. Tasks that legitimately take longer — slow CDN downloads,
ugoira encodes, rate-limited batch forwards (a 100-message channel copy
waits ~4 min on the per-chat token bucket) — had their lease expire
mid-run; the 30 s expiry sweep flipped the row back to pending and
another worker processed it again, double-sending.
run_with_lease now drives the handler through tokio::select! and
refreshes locked_until every 30 s while it runs. The heartbeat lives in
the same future as the handler, so a panicking worker still lets the
sweep recover the row (no leaked task keeping the lease fresh forever).
A task only reaches the queue after a failed send, so the fresh attempt
never ran post_send_actions (edit-before-forward prompt / channel
forward) — it failed before that point. The old guard skipped
post_send_actions for resumed tasks (batch_index > 0 or sent ids
present), which meant any send that needed a retry after partial
progress silently lost its forward and edit prompt.
post_send_actions is now run unconditionally on a successful queue send;
it executes exactly once, after the whole sequence completed.
AGENTS.md: document the twitter API entity decode and the /test report
HTML-decoded display; add the missing db.rs / media_sender.rs /
rate_limit.rs module rows; fix the statics location (handlers/statics.rs);
refresh test counts (~115, twitter live 5, pixiv api.rs 1, photo heavy
test); versioning convention now includes README.en.md.
README.md / README.en.md: add TELOXIDE_PROXY to the env variable list.
Twitter's syndication and GraphQL APIs return tweet text and display
names pre-escaped for HTML (> < & '); the caption builder
escaped the text again, so sent messages showed literal entities (e.g.
>^ω^< came back as >^ω^<). from_syndication_json now decodes the
API text before storing it — both the syndication path and the
TWITTER_AUTH_TOKEN GraphQL fallback route through it — so the caption
escapes exactly once and renders correctly.
The /test report is a plain-text message but printed the pre-escaped
caption and render fields; it now HTML-decodes them for display so the
report shows the rendered text.
Deleted tweets answer the syndication endpoint with HTTP 200 and a
TweetTombstone (no `errors`, no `id_str`). The body classifier only
knew the `errors` shape, so tombstones fell through to the
`no id_str -> Sensitive` branch and degraded to an empty result,
making the bot reply "No media found" for a deleted tweet.
- extract parse_syndication_body(); tombstone shape -> NotFound
- propagate NotFound from the TWITTER_AUTH_TOKEN GraphQL fallback
instead of swallowing it into empty_fetched
- unit tests for all body classes + live regression test on a real
tombstoned tweet
P0 — level rework + redaction:
- info now carries only lifecycle, per-post business results (sent /
forwarded / copied / template applied), admin actions and anomalies
(upload fallback, retry enqueue; dead-letter stays error).
- Per-request detail moved to debug: message/command logging, URL
extraction, fetching/fetched, link-cache hits, media-group batch sends,
queue processing (enqueue/processing/completed/rescheduled), photo
processing (downscale/transcode), inline queries, sensitive-tweet note.
- Full user-submitted URLs and message text now appear only at debug; at
info and above links are printed via the normalized cache key.
P1 — request correlation:
- handlers::log_key() maps a URL to its normalized post key
(twitter:<id> / pixiv:<id> / bsky:<handle>/<rkey>). The whole lifecycle
of one link (fetch -> send -> cache -> fallback) now logs [key=...], so
multi-worker logs can be correlated by grepping the key.
Convention documented in AGENTS.md.
site::fetch retried every PixivError, so a bad/expired token (403) or a
deleted artwork (404) burned all 3 attempts with backoff against pixiv's
API for nothing. Add PixivError::Status(u16) — the app-API calls now
surface the HTTP status — and retry only the transient classes: network
errors, 429 and 5xx. 4xx / Api (token errors) / Json / NoAuth are
returned immediately. The classification is a pure helper
(fetch_error_is_retryable) with unit tests.
The old stop only set an atomic flag checked between jobs: a worker
blocked in recv() never woke (the channel was never closed), and queued
jobs were neither drained nor abandoned in a defined way despite the
"drains up to 256 jobs" comment. Now stop_url_workers sets the flag,
drops the sender so blocked recv() calls wake with None, and awaits the
worker JoinHandles (each finishes its in-flight job first). main awaits
it inside the existing 30s shutdown timeout.
Smaller/faster production binary (verified: cargo build --release -p
xmedia-bot builds clean with the new profile). panic=abort is
intentionally not set — queue workers and db closures rely on JoinHandle
catching panics, which abort would defeat.
Full English translation of README.md — features, quick start, webhook
deployment (domain + IP-only with acme.sh), env table, command table.
The Chinese README stays the primary one.
A typo in EDIT_MESSAGE_TTL_SECONDS / WEBHOOK_PORT etc. used to silently
fall back to a default, so the bot ran with different behavior than the
operator intended (or failed much later on a bare .expect). Unparseable
values now log a loud warning naming the variable; invalid webhook
settings still surface as a hard .expect in webhook mode.
The stop sequence awaited the queue workers, which can be mid-download
(30s client timeout) or mid-ugoira encode (minutes). A stuck worker would
hold shutdown forever; now the process logs and exits after 30s.
