Closes Fase 3.3b. Daemon now tells the server the moment a session's
first HLS segment + init.mp4 land on disk; the web side flips
streaming_session.ready_at = NOW(), which its SSE endpoint pushes to
subscribed players so the loading UI flips from "Preparando…" to
"Stream listo" without polling HEAD on the segment URL.
Surface:
- New Client.MarkSessionReady(ctx, sessionId) HTTP method →
POST /api/internal/agent/session-ready.
- New engine.HLSSession.ReadyCount() + FromCache() accessors so the
watcher goroutine doesn't reach into private state.
- New cmd.watchSessionReady(ctx, client, hsess, sessionId) goroutine
polls ReadyCount every 200 ms with a 60 s deadline + short-circuits
for cache-HIT sessions (ready the moment StartHLSSession returns).
- Daemon callback spawns it right after streamSrv.HLS().Register so
the watcher's lifecycle matches the session's.
Best-effort: a transient network failure on the webhook is logged + the
goroutine exits — the player's existing HEAD-probe retry path still
discovers ready state independently. The webhook is an acceleration,
not a hard dependency.
Daemon now runs engine.DetectHWAccelDiagnostic at startup (instead of the
lighter DetectHWAccel) and ships the full picture — ffmpeg version,
resolved binary path, HW encoders compiled in, device files / drivers
detected — up to the server in the RegisterRequest payload.
Why: the most common cause of slow first-play is a software-only ffmpeg
build. Surfacing the diagnostic in the web AgentsTab "Diagnose
transcoder" modal lets a user see *why* their backend landed on libx264
(e.g. brew's default formula ships without --enable-nvenc, or the
container is missing /dev/nvidia0) without SSHing in to run `unarr
probe-hwaccel` manually.
Also emits a single `[transcode]` startup log line summarising the same
data — convenient for `journalctl --user -u unarr | grep transcode`.
Bounded by a 10 s context so a hung ffmpeg binary can't stall daemon
startup forever.
Two bugs in 0.9.6/0.9.7 caused an infinite restart loop after a Force update
signal: the CLI never reported the upgrade outcome, so `upgrade_requested`
stayed `true`; AND `applyAutoUpgrade` called `os.Exit(0)` even when the
target version equalled the current one, so systemd respawned and saw the
flag again.
- new Client.ReportUpgradeResult → POST /api/internal/agent/upgrade-result
- applyAutoUpgrade calls it on success / failure / no-op
- no-op case detected up front (same version) — skips Execute + Exit,
clears server flag instead
OnUpgrade now downloads + replaces the binary and exits in a background
goroutine; the service supervisor (systemd Restart=always) respawns on the
new version. Removes the "run unarr update" manual step after pressing the
web's Force update button.
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.
A usenet-enabled agent silently produces corrupt files when par2 is
not installed: bad NNTP segments go unrepaired and unrar reports
checksum errors. Likewise, no unrar/7z means RAR-packed downloads
can't be unpacked at all.
When the registered agent has the usenet feature, check par2 and the
extractor (unrar/7z) in PATH and log a loud WARNING for each missing
one, mirroring the existing ffmpeg-for-HLS warning.
Add `unarr vpn` (status/enable/disable, with `status --check`) to manage the
managed WireGuard split-tunnel from the CLI. The daemon now reports its
split-tunnel state (active, mode, exit server) to the web on register and on
every sync, and sends its agent id when fetching the VPN config so the web can
arbitrate the single WireGuard slot (1 VPNResellers account = 1 WG keypair = 1
concurrent connection): the first agent claims it; the rest are told to run
OpenVPN on their own host (1 WireGuard + up to 9 OpenVPN = 10).
`status --check` passes probe=1 so it validates provisioning without claiming
the slot. VPNActive drops omitempty so a downed tunnel reaches the server and
frees the slot. Bumps to 0.9.2 with CHANGELOG + README VPN section.
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.
- Mirror pool with health tracking and exponential backoff for failed hosts
- Agent client routes requests through mirror pool with retry semantics
- New `unarr mirrors` command to inspect mirror state and force failover
- `unarr status` now detects 401 from /agent/register and suggests `unarr login`
instead of the generic "Could not fetch account info" message
- Config supports multiple ScanPaths for upcoming multi-path library scan
- Draft plan for bidirectional library sync (CLI ↔ Web) under Docs/plans/
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.
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.
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.
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).
- Use a dedicated 10-minute HTTP client for library-sync so libraries
with hundreds or thousands of items no longer time out
- Show actionable ffprobe-not-found error: detects Docker and suggests
FFPROBE_PATH env var, config.toml setting, or package install
- Include static ffprobe binary in Docker image (johnvansickle.com)
- Bump version to 0.6.2
- 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)
Without a SetReadDeadline, a silently dead WebSocket (e.g. Cloudflare
dropping the connection without a close frame) would block readLoop
forever. The daemon would appear connected but never receive tasks,
and never fall back to HTTP polling.
- Send RFC 6455 pings every 30s (resets Cloudflare's idle timer)
- SetReadDeadline of 45s, refreshed on every pong and text message
- SetWriteDeadline of 10s on all writes to prevent blocked sends
- On timeout, readLoop emits "disconnected" → HybridTransport falls
back to HTTP and starts WS reconnection loop
Include StreamPort, LanIP, and TailscaleIP in RegisterRequest so the
server knows the agent's stream endpoints from the moment it registers,
not just after the first heartbeat. Align HeartbeatRequest field order
with RegisterRequest for consistency.
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
- Fix stream handler resource cleanup and ffprobe error handling
- Auto-scan: daemon scans library daily (configurable via config.toml)
[library] auto_scan = true, scan_interval = "24h"
- Force start: tasks with forceStart=true bypass concurrency semaphore
(like Transmission's Force Start — opens temporary extra slot)
- Stall timeout default: 30m instead of unlimited, prevents dead torrents
from permanently blocking download slots
- ForceStart field in agent.Task for CLI/server communication
- Migration wizard from Sonarr/Radarr/Prowlarr (unarr migrate) [pre-beta]
- Auto-detect instances via Docker, config files, port scan, Prowlarr
- Import wanted list (monitored+missing movies/series)
- Import download history and blocklist to avoid re-downloading
- Extract debrid tokens from *arr download clients
- Quality profile mapping to preferred_quality config
- DISTINCT ON PostgreSQL query for optimal torrent selection
- JSON export with --dry-run --json (text to stderr, JSON to stdout)
- Media server detection (Plex/Jellyfin/Emby) in unarr init
- Detects library paths and offers them as download directory options
- Debrid auto-configuration in unarr init
- Scans *arr instances for debrid tokens
- Validates and saves via API if user confirms
- New preferred_quality setting in config (2160p/1080p/720p)
- Library scan command (unarr scan) with ffprobe metadata extraction
- Go deps: cobra 1.10.2, fatih/color 1.19, tablewriter 1.1.4,
anacrolix/torrent 1.61, charmbracelet/huh 1.0, pion/webrtc 4.2.11
- GitHub Actions: checkout v6, setup-go v6, golangci-lint-action v9,
codecov-action v5, ghaction-upx v4, goreleaser-action v7
- CI matrix: drop Go 1.22, test on 1.24 + 1.25
- Migrate tablewriter API from v0 to v1 (breaking change)
- Fix data race in WSTransport.readLoop (pass conn as parameter)
- Add file.Sync() before close in debrid and usenet downloaders
- Improve progress tracker: dedup MarkDone, re-mark dirty on flush error
- Add daemon state persistence and stale resume file cleanup
- Add TriggerPoll for WebSocket resume actions
- Improve stream server with graceful shutdown and connection tracking
- Add desktop notifications for download completion
- Add media file organization with Movies/TV Shows detection
- Improve usenet downloader with progress tracking and resume support
- Add self-update package with GitHub release verification
- Downgrade tablewriter to v0.0.5 (v1.x API breaking change)
Complete usenet download support for unarr CLI:
- NZB XML parser with password extraction from <head> meta
- yEnc decoder with CRC32 verification
- NNTP client with TLS, auth, and connection pool (up to 10 conns)
- Segment downloader with parallel workers and progress reporting
- Post-processing: par2 verify/repair, unrar/7z extraction with password support
