Daemon CORS allowlist was hardcoded to torrentclaw.com + localhost. Browsers
playing from any other official mirror (.to, onion, www., staging.) received
200 + body from the daemon's HLS server but no Access-Control-Allow-Origin
header, so the response was dropped client-side. Probe loop treated every
candidate as a failure and surfaced "No se puede conectar con tu agente
— 404 todos los canales" even though the tunnel + ffmpeg were healthy.
Static baseline now includes the full known mirror set (.com / www / app /
staging / .to / www.to / built-in onion). At startup the daemon also fetches
/api/mirrors with IPFS fallback and merges the live origins, so a future
mirror addition does not require a CLI rebuild.
Gives the daemon a public HTTPS hostname (`https://<random>.trycloudflare.com`)
so the in-browser player on torrentclaw.com plays cross-network without
Tailscale or port forwarding — the mixed-content block that was breaking
HTTPS-page → HTTP-daemon fetches is gone. Bytes proxy through CloudFlare,
never through TorrentClaw infra (preserves the aggregator legal posture).
New surface:
• `internal/funnel/` package: subprocess wrapper + auto-download for
cloudflared. Linux amd64/arm64/armhf/386 fetched from GitHub releases
on first run, validated by ELF magic + size sanity, O_EXCL partial
write so concurrent daemons don't clobber each other.
• `unarr funnel on/off/status` cobra command (sibling of `unarr vpn`).
• Daemon supervisor goroutine keeps cloudflared up across crashes + CF's
~6h Quick Tunnel rotation. Exponential backoff (2 s → 5 min). On exit
the reported URL is cleared so the web stops handing out a dead host.
• Wire: agent registers/syncs a FunnelURL field; web prefers it over
Tailscale/LAN for in-browser playback (HlsStreamPlayer + Stremio
addon).
Default ON for fresh installs (NAS/Docker get it without terminal-in);
existing configs that pre-date the feature stay off until the operator
opts in with `unarr funnel on`.
Docker image now bundles cloudflared (built per TARGETARCH via buildx).
Also fixed: libx264 'frame MB size > level limit' on anamorphic >16:9
sources. The level we hint to libx264 was derived from height alone,
which busted on 720p cinemascope (1728×720 = 4860 MBs > level 3.1's
3600). Bumped each tier: 720p → 4.0, 1080p → 4.1.
Version: 0.9.4 → 0.9.5.
Drops the custom WebRTC DataChannel pipeline + pion deps + WSS signaling
client + wire framing. Every in-browser playback now uses HLS over HTTP
from the daemon (Tailscale/LAN/UPnP). Browser P2P never re-enabled.
Wire renames (incompatible with web < 2026-05-26): agent.WebRTCSession
=> agent.StreamSession, SyncResponse.WebRTCSessions (JSON: webrtcSessions)
=> StreamSessions (JSON: streamSessions). MIN_AGENT_VERSION is bumped
to 0.9.4 on the web side so older agents see an upgrade card.
Also fixes the libx264 'VBV bitrate > level limit' abort by clamping
the encoder bitrate to the effective output height instead of the
requested label (carried over from the prior 0.9.3 unreleased work).
The seed_file vertical (mode=seed_file handler + engine.SeedFile) was
retired with the in-browser P2P player. [downloads.webrtc] config block
deleted; existing TOML files with the section still parse fine.
Asking for 2160p quality on a 720p source kept the daemon's qcap.VideoBitrate
at 25 Mbps even after outputHeight was clamped to the source. The level
H264LevelForHeight picks for the 720p output is 3.1 / 4.0, which rejects any
VBV >20 Mbps — libx264 then exited with "VBV bitrate (25000) > level limit"
on every restart, ffmpeg auto-restarted 3 times, master.m3u8 never appeared,
and the player got stuck at "Preparando sesión".
Re-derive the (height, bitrate) cap from the EFFECTIVE outputHeight via the
new capForHeight helper. Result: 720p source asked for 2160p → outputs 720p
with the 3500 kbps bitrate the level actually accepts. ffmpeg runs cleanly,
master.m3u8 appears, playback starts.
The web also clamps effectiveQuality to source resolution before the session
row is written, so the daemon mostly receives sane labels. This change keeps
the daemon defensive against (a) older web clients that still ask for
upscaled qualities, and (b) future quality="original" requests where qcap
is empty and Transcode.VideoBitrate could overshoot the level too.
A failed usenet extract sets task.ErrorMessage to the full unrar/par2
dump (multi-KB). Sent raw, the web /agent/status route rejected it and
the terminal report failed, leaving the task stuck non-terminal.
Cap the reported errorMessage at 2000 bytes (rune-safe) in the status
snapshot, matching the server's stored length.
In-process userspace WireGuard tunnel (wireguard-go + gVisor netstack) for
the managed-VPN add-on. No root, no OS routing changes: only the embedded
anacrolix/torrent client's peer + tracker traffic is routed through the
tunnel, so the swarm and trackers see the VPN IP, not the user's home IP.
unarr's control plane (API, heartbeats) keeps using the normal net.
- internal/vpn: FetchConfig (GET /api/internal/agent/vpn-config, Bearer auth,
typed errors for disabled/not_provisioned/slot_on_device) + Up (parse .conf
→ uapi, CreateNetTUN, device Up) + DialContext/ListenPacket adapters.
- engine/torrent.go: when a tunnel is set, wire TrackerDialContext +
HTTPDialContext + TrackerListenPacket to netstack, DisableUTP, and
AddDialer(NetworkDialer{tcp, netstack}) for peer conns.
- config: downloads.vpn.enabled flag.
- daemon: bring up the tunnel before the torrent client; non-fatal on
failure (logs + downloads in the clear); slot_on_device warns the user.
- version bump 0.8.1 → 0.9.0.
Pairs with the web VPN add-on (dormant behind NEXT_PUBLIC_VPN_ENABLED).
Runtime-verified once a VPNResellers trial provides a live endpoint.
Phase 3 security audit follow-up. Medium and low-severity hardenings
plus a deferred-work plan for the cross-repo stream-token rollout.
Stream server CORS: replace the wildcard Access-Control-Allow-Origin
with an allowlist that echoes back only torrentclaw.com,
app.torrentclaw.com, the local Next dev port (3030 — matches the web
repo package.json) and any extras the operator adds via the new
downloads.cors_extra_origins TOML key. A Vary: Origin header is now
emitted whenever the request carries an Origin header so an
intermediate cache cannot serve a stale ACAO to a different origin.
URL scheme guard: openBrowser and OpenPlayer refuse any URL that is
not http(s). Combined with passing the URL after "--" wherever the
launched helper supports it (open, mpv, vlc, cvlc), this stops a
leading "-" from being parsed as a switch by the spawned process.
State file permissions: WriteState now writes 0o600 so the agent ID,
PID and counters cannot be enumerated by another local user on a
shared host. Matches the existing config file mode.
ZIP slip defense-in-depth: extractZip extracts the safety check into
safeZipPath, which canonicalises the entry name (normalising
backslashes to "/"), rejects "..", "../" prefix and "/../" interior
components, and verifies the final destination stays inside destDir
before opening any file.
Mirror fallback: documented the design for multi-provider
mirrors.json hosting in the comment block on DefaultStaticFallbackURLs
and added a follow-up note about signing it with the same ed25519
release key. The list is kept at one provider until the second host
is provisioned and added to torrentclaw-web's STATIC_FALLBACKS.
Deferred work: a new plan document Docs/plans/security-stream-token.md
covers the per-task stream token (Phase 2.2 of the original audit)
which requires coordinated web + CLI work and ships separately.
Phase 2 security audit follow-up. Three independent hardenings against
the unauthenticated daemon surface, the long-lived agent SSE stream
and the self-update channel.
UPnP is now opt-in. The stream port + /hls endpoints have no auth, so
publishing them on the WAN via the gateway was a default that exposed
active downloads to anyone scanning the operator's external IP. New
config downloads.enable_upnp (default false) gates the mapping; LAN
and Tailscale clients continue to work unchanged. A startup log makes
the new default visible.
The agent SSE reader now uses a bounded bufio.Scanner instead of an
unbounded ReadString. A hostile or buggy server can no longer grow
daemon memory by streaming a single line forever or by emitting
unbounded data: continuation lines — both are capped at 256 KiB and
1 MiB respectively, and an error is surfaced so SignalLoop reconnects.
Self-update now verifies an ed25519 signature over checksums.txt when
the binary was built with a release public key embedded (injected via
goreleaser ldflags from RELEASE_SIGNING_PUBKEY). The companion
scripts/sign-checksums runs in the release workflow when both the
public-key variable and the private-key secret are present, uploading
checksums.txt.sig next to the existing checksums file. Builds without
the embedded key continue to update with SHA256-only verification; a
--allow-unsigned flag is provided so users on a signed build can
still install pre-signing releases or recover from an accidental
unsigned release.
A new scripts/gen-release-key helper documents the one-time keypair
generation procedure required before flipping signing on.
Phase 1 security audit follow-up:
- Reject HLS session IDs that aren't safe filesystem components
(regex allowlist) to defend against path traversal via a buggy or
compromised server. Applied at StartHLSSession and at the /hls URL
handler; invalid IDs share the 404 of unknown sessions so the
accepted format isn't enumerable.
- /health no longer leaks the active filename, taskID prefix or client
IP to non-loopback callers. Uses net.IP.IsLoopback so IPv4-mapped
IPv6 (::ffff:127.0.0.1) is recognised and the empty-string parse
failure stops bypassing the boundary.
- unrar/7z passwords now travel through stdin instead of -p<password>
in argv, removing /proc/<pid>/cmdline disclosure. Control characters
in the password are rejected up front so a hostile NZB cannot feed
extra prompt answers. Both invocations are bounded by a 30-minute
context to stop indefinite hangs if the tool ever decides to prompt.
Three related fixes around 4K-source transcoding that left the web
player stuck on "preparing session" with no useful diagnostics:
1. Dynamic -level:v derived from output height (hls.go, transcoder.go).
The previous fixed "4.0" silently rejected anything taller than 1080p
inside libx264 — "frame MB size > level limit", "DPB size > level
limit" — and emitted unplayable segments. Helper H264LevelForHeight()
now picks 4.0 / 5.0 / 5.1 / 6.0 from the actual encode height.
2. New `unarr probe-hwaccel` diagnostic command. Lists the HW encoders
compiled into ffmpeg, the device files / drivers present, and the
backend the daemon would actually pick today. Surfaces the canonical
gotcha: a host with an RTX 3090 + nvidia-smi but a Homebrew ffmpeg
built without --enable-nvenc still falls back to libx264 software.
3. Register payload now includes hwAccel + maxTranscodeHeight so the web
side can suggest a smaller alternate quality before the user even
tries to play a 4K source on a software-only host. Software-only =
1080p cap, any HW backend = 2160p cap.
Follow-ups from /critico review on commits eb2548f + 40e7977. No
functional change.
- engine/hls.go restartFromSegment now reads `s.exited` under
`readyMu`. The field is documented as readyMu-protected (see field
declaration) and writers in waitFFmpeg / pollSegments hold the lock
consistently; the previous direct read produced a `go test -race`
warning under concurrent restart paths.
- engine/hls.go renderMasterPlaylist drops the `defaultIdx := -1`
branch that was unreachable (no rendition was ever flagged DEFAULT
or AUTOSELECT). Output is unchanged; the source is just shorter.
- engine/hls.go subtitle "(forzados)" suffix → "(forced)". Daemon
convention is English; the web client localises if needed.
- engine/hls.go hlsStderrCapture now also caps single-write payloads
larger than maxStderrBuf (was only capping the cumulative buffer).
- engine/hls.go waitFFmpeg restart-window reset drops the redundant
`!IsZero` guard — a zero time is far enough in the past that the
`> restartWindow` branch covers it.
Reliability hardening pass for the HLS daemon. None of these change the
public API, all reduce the chances of an end-user seeing a broken
session in production.
- engine/hls.go waitFFmpeg now supervises ffmpeg: on a non-graceful
exit while the session is still in use, restart from the last good
segment up to 3 times within a 60 s window. Beyond that we give up
and log the file as broken — better than a perpetually black player
with no error.
- engine/hls.go CleanupHLSOrphanDirs() removes tmpdirs older than 1 h
at startup; cmd/daemon.go calls it before streamSrv.Listen so a
daemon crash + restart doesn't leak gigabytes of segment files.
- engine/hls.go StartHLSSession wraps ffprobe in a 15 s timeout. A
hung probe on a slow remote fs would otherwise block the goroutine
forever and the player would stay on "Preparando sesion".
- engine/hls.go hlsStderrCapture buffer is capped at 64 KiB; a
misbehaving ffmpeg that emits megabytes without newlines used to
grow daemon memory unbounded.
Follow-ups on the daemon HLS pipeline (0fc0e1c):
- engine/hls.go HLSSession.Register now closes every other active
session in the registry. Modeled as "one viewer == one transcode" so
repeated quality switches or page reloads don't leave orphan ffmpegs
saturating the CPU until the idle sweeper reaps them 30 min later.
- engine/hls.go restartFromSegment kills + respawns ffmpeg with
-ss / -output_ts_offset / -start_number when the browser asks for a
segment far ahead of the writer head. Segments already on disk stay
cached. Without this, a user dragging the scrubber to minute 30 of a
fresh stream blocks until the encoder reaches minute 30 in real time.
- engine/hls.go subtitle disambiguation: never set DEFAULT=YES on any
rendition (anime forced "signs only" tracks were autoselected and
rendered nothing during opening dialogue, looking broken). Names get
numeric suffixes when language is duplicated; FORCED tracks get a
"(forzados)" suffix.
- engine/hls.go ProbeInfo() exposes codec / audio / subtitle metadata
to the new GET /hls/<id>/probe.json endpoint for the player's info
badge + bandwidth logic.
- engine/hls.go scale chain fix: chains a trunc(iw/2)*2 scale after
the height cap so libx264 stops rejecting odd widths (853x480 etc.).
- engine/hls.go HW encoder tuning: NVENC -preset p4 -rc vbr -tune hq,
QSV -preset medium.
- engine/stream_server.go routes /hls/<id>/probe.json to the session.
- cmd/daemon.go runs an idle sweeper goroutine every 5 min, reaping
sessions whose last segment fetch was >30 min ago.
Introduces an HLS-over-HTTP path as Plan B for in-browser streaming. The
WebRTC + MSE pipeline keeps working untouched; the new path is selected
when the backend sets transport="hls" on a streaming session.
Daemon scope:
- engine/hls.go: HLSSession + HLSSessionRegistry. Spawns ffmpeg with
-f hls -hls_segment_type fmp4 + force_key_frames aligned with 4 s
segments. Pre-renders master + media playlists from the probe duration
so the browser knows the total timeline before any segment exists,
fixing seek/duration/pause/multi-track issues seen with the live fMP4
pipe.
- engine/probe.go: enumerate every audio + subtitle track instead of
collapsing to a single default audio track.
- engine/stream_server.go: route /hls/<id>/{master.m3u8,video/...,
subs/...} to the matching session. Emit a synthesised single-VTT
subtitle playlist per text track; bitmap subs (PGS/DVB) skip silently.
- cmd/daemon.go: branch on WebRTCSession.Transport == "hls" to register
an HLS session instead of running the legacy DataChannel pump.
- agent/types.go: WebRTCSession.Transport + AudioIndex fields.
Backend + web sides land in a follow-up commit.
Two transcoder fixes for browser MediaSource Extensions parsing:
1. -ar 48000 -ac 2 on the audio output. Source 5.1 / 7.1 streams produced
a moov atom Chrome CHUNK_DEMUXER refuses to parse, even when the video
metadata is fine and a non-MSE video element accepts the same file.
Forcing AAC-LC stereo 48 kHz makes the moov shape MSE-compatible.
2. -frag_duration 1000000 (1 second) so each moof+mdat fragment caps at
~1s of media. Without it, ffmpeg only splits at keyframes and high-
bitrate 1080p produces 8 MiB+ mdat boxes — MSE waits for the whole
mdat before parsing the first fragment, so playback never starts.
3. -movflags +negative_cts_offsets so b-frames carry the right pts/dts
offsets and the playhead doesn't reset every fragment.
4. New range_req debug log to make sizing bugs greppable.
1. -profile:v main + -level:v 4.0 to avoid Chrome's HW decoder path that
failed with "VaapiWrapper: failed initializing for h264 high" on Linux.
2. setparams to rewrite HDR HEVC color metadata to SDR Rec.709 so browsers
don't reject wide-gamut output.
3. serveRange caps `want` by estimated final size (not current). ReadAt
blocks until ffmpeg catches up — that's the right behaviour. Returning
RangeEnd inmediato was making the browser abort with "Format error".
4. Debug log on every range_req.
The previous scale expression `min(iw,iw*H/ih)':'min(ih,H)` produced odd
widths (e.g. 1425×720 for a 16:9 source capped at 720p) which libx264
refuses with `width not divisible by 2`, killing the encoder before a
single byte was written.
Switch to `scale=-2:H:force_original_aspect_ratio=decrease`, which
derives a width that preserves aspect ratio AND is rounded to a multiple
of 2. Always set `-pix_fmt yuv420p` so 10-bit HEVC sources are downcast
to the 8-bit format browser <video> elements actually decode.
Also add `-y`, guard nil pipe in Close(), and the related transcode
plumbing for browser-decided per-session quality.
Adds WebRTCSession.Quality to the sync payload so the daemon can pick a
MaxHeight + bitrate per session instead of using the global config cap.
resolveQualityCap() maps the label to a (height, b:v) pair and
buildStreamSource() promotes a passthrough decision to ActionTranscodeVideo
when the source resolution exceeds the cap (4K source on a phone client
with quality="720p" must transcode, not pass-through).
Also lands the transcode-on-by-default fix for legacy configs without a
[downloads.transcode] section so existing installs pick up h264+aac
fallback for HEVC/AC3 content without re-running setup.
Source files in HEVC, AV1, AC3, DTS, EAC3, etc. now transcode through ffmpeg
to fragmented MP4 (h264 + aac) on-the-fly when the browser would otherwise
play silent black. Decision matrix lives in engine.DecideAction:
passthrough → remux → audio-transcode → full video-transcode.
Architecture — temp file + growing-size source:
- engine.streamSource interface abstracts byte source. Two impls:
* diskFileSource: passthrough when codecs are already browser-friendly.
* transcodeSource: spawns ffmpeg writing to a /tmp/tc-stream-*.mp4 file.
A ticker polls file size and wakes blocked ReadAt callers as ffmpeg
produces output. Estimate of final size (bitrate × duration) is
announced over the wire so the browser's scrubber has something to
anchor on.
- dataChannelPump now reads from streamSource instead of *os.File. HELLO
carries Transcoding=true + an estimated total size; Seekable=true (we
read random-access from the temp file even while writing).
- Transcoder runtime resolved per session by buildTranscodeRuntime in
cmd/daemon: ffmpeg/ffprobe path lookup + HWAccel auto-detection
(NVENC/QSV/VAAPI/VideoToolbox).
- New [downloads.transcode] TOML section: enabled (default true), hw_accel
(auto), preset (veryfast), video_bitrate (5M), audio_bitrate (192k),
max_height (optional downscale), max_concurrent (safety cap).
Falls back to passthrough if ffprobe is missing, fails, or codecs are
already browser-friendly. tmp file is cleaned up on session shutdown.
Surfaces tracker-announce + WebRTC peer events that were previously
swallowed by the Critical filter. Required for diagnosing the browser
↔ Go piece-transfer issue uncovered during the e2e smoke (peers
connect, signalling brokers, WebRTC handshake completes, but
anacrolix's outbound seeding to webtorrent.js browsers — known
upstream weak spot, issues #402/#752/#805 — produces zero pieces).
No behaviour change in normal operation; only changes what gets
logged.
Closes the agent half of in-browser playback for arbitrary files. When
the web app inserts a download_task with mode="seed_file", the daemon
now wraps the on-disk file as a single-file torrent, adds it to the
existing WebRTC-enabled torrent client, and reports the generated
info_hash back so the browser can target /stream/<hash>.
Pieces:
- internal/agent/types.go: Task.FilePath (received from claim) +
StatusUpdate.InfoHash (sent back). Both serialise compatibly with
the matching Zod schemas in the Next.js sync route.
- internal/engine/seed_file.go: SeedFile(client, filePath, trackers)
builds the metainfo via metainfo.Info.BuildFromFilePath +
bencode.Marshal, then AddTorrent + DownloadAll() so anacrolix
hashes the file and flips pieces to "have" as it goes. The
libtorrent piece-size ladder is mirrored from wstracker-probe so
generated torrents are interoperable with mainstream clients.
SeedFileOnDownloader is the daemon-facing convenience wrapper —
bails loud when [downloads.webrtc].enabled = false instead of
silently producing a torrent no browser can find.
- internal/cmd/seed_file_handler.go: handleSeedFileTask invoked from
the existing OnTasksClaimed dispatcher in daemon.go for mode=
seed_file. Validates filePath, calls the engine helper, and pushes
the resulting info_hash via Client.ReportStatus. Failures (missing
file, WebRTC disabled, ffmpeg-style oddities) report status="failed"
+ errorMessage so the browser's WatchInBrowserButton can show the
reason instead of timing out at 60 s.
- internal/cmd/daemon.go: dispatcher learns the seed_file branch in
the same shape as the existing stream branch.
Tests (6 unit, all green):
- SeedFile rejects missing files + directories.
- SeedFile yields a deterministic info_hash for the same payload across
fresh clients (web client polls expecting this).
- SeedFileOnDownloader errors when WebRTC is disabled.
- chooseSeedPieceLength matches the ladder breakpoints.
- makeAnnounceList handles nil/empty/partial inputs.
Web side compatible: mode=seed_file is already accepted by the sync
schema; agent.Task.filePath + StatusUpdate.infoHash now propagate
through the existing claim/report endpoints. End-to-end browser ↔
unarr smoke is the next concrete verification step (needs a running
unarr-dev daemon plus library scan + a file with no source torrent).
Wires anacrolix/torrent's built-in webtorrent package so a browser
running webtorrent.js can fetch pieces from this CLI via WebRTC data
channels. The daemon stays the seeder; we never relay bytes through
TorrentClaw infrastructure — same legal posture as today.
Changes:
- internal/config: new [downloads.webrtc] section
(enabled/trackers/stun_servers/turn_servers/turn_user/turn_pass).
Disabled by default, opt-in via config.toml. When enabled but
trackers / STUN slices are empty, defaults are reapplied on Load() so
users get a working setup with a single `enabled = true`.
- internal/engine: TorrentConfig gains WebRTCEnabled / WebRTCTrackers
/ ICEServers; NewTorrentDownloader populates ClientConfig.ICEServerList
and forces NoUpload=false when WebRTC is on (browsers can't pull
otherwise). buildMagnet now accepts variadic extra trackers and the
downloader method prepends WSS trackers so anacrolix's
webtorrent.TrackerClient picks them up first.
- internal/engine/webrtc.go: BuildICEServers helper converts the TOML
WebRTCConfig into []webrtc.ICEServer with shared TURN credentials.
- internal/cmd/daemon.go + download.go: pass WebRTC config through to
the engine.
Tests (8 new, all green; full suite 0 lint issues, 0 vet):
- buildMagnet free function: defaults-only, with extras, trim+empty-skip
- downloader method: WebRTC disabled keeps WSS out, enabled prepends them
- BuildICEServers: nil when disabled, STUN-only path, TURN+credentials
- NewTorrentDownloader: full WebRTC-enabled construction (logs WebRTC
peer enabled, magnet contains wss://tracker.torrentclaw.com)
End-to-end smoke (browser ↔ unarr peer transfer) is deferred to a
manual test once tracker.torrentclaw.com WSS is live.
Three root-cause fixes for VLC showing a black screen when opening a
stream from a different network or via Tailscale:
1. PrioritizeTail: when VLC opens an MKV/MP4 stream it immediately seeks
to the end of the file to read the container index (seekhead/moov
atom). For active torrents those end-pieces aren't downloaded yet, so
the reader blocks indefinitely. PrioritizeTail() opens a background
reader positioned at the last 5 MB, keeping those pieces at high
priority until ctx is cancelled or they finish downloading.
2. /health endpoint: GET /health returns a lightweight JSON response
{"status":"ok","streaming":bool,...} so connectivity can be tested
with a simple curl from any device before involving VLC.
3. Per-request logging: every incoming /stream request now logs the
client IP and Range header, making it trivial to confirm whether
remote/Tailscale clients are reaching the server at all.
- task.go: fix deadlock in ToStatusUpdate() — calling Percent() (which
RLocks) while already holding RLock caused deadlock when a writer was
waiting; compute percent inline instead
- usenet.go: fix data race in Cancel() — tracker and taskDir were read
without the mutex while Download() writes them under it; read all
fields under the same lock
- upnp.go: fix UPnP Remove() blocking shutdown — run cleanup in goroutine
with 10s deadline (removeNATPMP worst case is 3s dial + 5s deadline)
- daemon.go: add path traversal protection for stream requests — validate
sr.FilePath is within configured directories before os.Stat; defends
against compromised API server sending arbitrary paths
- client.go: add wakeClient without timeout for long-poll wake endpoint
where context controls cancellation
- sync.go: trigger immediate sync when entering watching mode so stream
requests are picked up without waiting for the next scheduled interval
Replace the WebSocket + Cloudflare Durable Object architecture with a
single POST /sync endpoint. The CLI now operates autonomously with local
state (tasks.json) and syncs bidirectionally via adaptive-interval HTTP
polling (3s watching, 60s idle).
- Remove transport_ws, transport_hybrid, transport_http (~2,600 lines)
- Add SyncClient with adaptive interval loop
- Add LocalState for CLI-side task persistence
- Add TaskStateFromUpdate() helper (DRY)
- Extract finalize() to deduplicate processTask/processTaskRetry
- Consolidate shortID() into agent.ShortID (was in 3 packages)
- Wire GetActiveCount so `unarr status` shows active tasks
- Remove poll_interval, heartbeat_interval, ws_url from config
- Simplify ProgressReporter (sync replaces direct HTTP reporting)
- Register WatchReporter cancel funcs in streamRegistry so they get
cancelled when switching to a different stream (prevents goroutine leak)
- Re-notify streamReady when the server is already serving the requested
task (handles duplicate stream requests from the web UI)
- Rewrite tests for byte-based tracking semantics, remove dead
parseRangeStart tests
EstimatedProgress now returns video duration in seconds (from ffprobe).
WatchReporter sends Position and Duration fields when available, giving
the server precise playback time instead of just a percentage.
Replace Range-header-based progress tracking with a trackingReader that
measures actual bytes read per connection. This gives accurate playback
position even for local/NAS files where VLC buffers aggressively.
- Token bucket rate limiter at 2x video bitrate (from ffprobe)
- CAS loops for lock-free atomic progress updates without regression
- probeMediaInfo extracts bitrate + duration via ffprobe (3s timeout)
- Defense-in-depth: only probe regular files, reject FIFOs/devices
- Remove dead parseRangeStart function
- Consistent [stream] log prefix
Replace anacrolix/upnp with huin/goupnp + custom NAT-PMP (RFC 6886)
implementation. NAT-PMP is tried first (faster, more compatible with
TP-Link routers), with UPnP-IGD SOAP as fallback. Gateway detection
reads /proc/net/route for accuracy. Includes unit tests with mock
NAT-PMP server and permanent e2e tests (build tag manual).
Track the highest byte offset served by the stream server to estimate
playback progress (0-100%). A WatchReporter goroutine sends progress
to POST /api/internal/agent/watch-progress every 10s during streaming.
- Add maxByteOffset + totalFileSize to StreamServer for Range tracking
- Add FileSize() to fileProvider interface (all 3 providers)
- New WatchReporter: periodic progress reporter tied to daemon context
- New WatchProgressUpdate type with optional progress/position/duration
- Wire reporter into all 3 stream paths (task stream, disk stream, active download stream)
- Replace `upgrade` stub with real command (alias for `self-update`)
- Also register `update` as alias: `unarr update` works too
- Rewrite `status` to show full config, disk usage, daemon state, and
update availability with colored sections
- Add version check cache (1h TTL) so `status` is instant on repeat runs
- Guard against division by zero on empty filesystems
- Guard against negative durations from clock skew
- Guard against stale PID via heartbeat recency check (2 min)
- Add comprehensive test coverage across agent, engine, upgrade, usenet,
arr, library, mediaserver, and UI packages
- Improve Makefile coverage target to exclude cmd/ glue code
