From 78c16c295e08456042543f23ccf513a64b54c2ea Mon Sep 17 00:00:00 2001 From: Deivid Soto Date: Wed, 8 Apr 2026 23:36:00 +0200 Subject: [PATCH 001/108] test: add comprehensive test suite for engine, agent and cmd packages MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Refactor download.go and stream.go with downloadDeps/streamDeps structs for dependency injection, enabling unit testing without real I/O - download_test.go: 15 tests — input validation, mock downloaders, method selection, cobra Args, deadlock detection - stream_test.go: input validation, noOpen flag, engine error handling - client_test.go: context cancellation, timeout, full Sync roundtrip, watch-progress and HTTP error unwrapping - sync_test.go: TriggerSync on watching transition, adjustInterval - torrent_test.go: TorrentDownloader lifecycle without network - stream_server_test.go: HTTP server lifecycle, SetFile/ClearFile, concurrent requests, Shutdown releases port, content-type - manager_integration_test.go: full pipeline — success, torrent→debrid fallback, all-fail, multi-concurrent, ForceStart, OnTaskDone, recent-finished drain, cancel mid-download, organize - usenet_test.go: Cancel/Pause race regression test (run with -race) - daemon_test.go: isAllowedStreamPath table tests - CI: split coverage gate to engine+agent only (50% threshold); cmd coverage still reported but not gated (interactive UI commands) - lefthook: add pre-push hook with go test -race -count=1 -timeout=120s --- .github/workflows/ci.yml | 28 +-

vulnerabilities MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - 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

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. --- internal/cmd/stream_handler.go | 7 +++ internal/engine/stream.go | 32 ++++++++++++ internal/engine/stream_server.go | 44 ++++++++++++++++ internal/engine/stream_server_test.go | 74 +++++++++++++++++++++++++++ internal/engine/stream_test.go | 28 ++++++++++ 5 files changed, 185 insertions(+) diff --git a/internal/cmd/stream_handler.go b/internal/cmd/stream_handler.go index aec884b..fa61220 100644 --- a/internal/cmd/stream_handler.go +++ b/internal/cmd/stream_handler.go @@ -148,6 +148,13 @@ func handleStreamTask(parentCtx context.Context, at agent.Task, reporter *engine task.StreamURL = srv.URLsJSON() log.Printf("[%s] stream ready: %s (url: %s)", at.ID[:8], eng.FileName(), srv.URL()) + // Pre-descargar los últimos 5 MB del archivo para que el moov atom (MP4) + // o el seekhead (MKV) estén disponibles cuando VLC los pida al abrir el + // stream.

charset=UTF-8 Content-Transfer-Encoding: 8bit Operators no longer have to install ffmpeg manually. Both the release tarballs (5 platforms × 2 binaries) and the Docker image now ship a working ffmpeg + ffprobe pair adjacent to the unarr binary; ResolveFFmpeg / ResolveFFprobe pick them up via the "adjacent to executable" branch with zero configuration.

The static GPL builds need glibc + libmvec / libgcc_s; gcompat alone is not enough (vector-math symbols unresolved).

This package decides per request whether to: • direct-play — input already MSE-compatible, just remux to fMP4 • transcode — re-encode video (libx264 / NVENC / QSV / VAAPI / VideoToolbox) + audio (AAC), fragment to fMP4 Pieces: - internal/streaming/transcoder.go — AnalyzeCompatibility decides the recipe from a parsed mediainfo. CompatibilityReport carries the reasons so the player UI can show "transcoding video: HEVC → H.264". - internal/streaming/ffmpeg_args.go — BuildFFmpegArgs assembles the argv for ffmpeg. Direct play uses `-c copy`; transcode uses libx264 or the selected HW encoder. Output is always fragmented MP4 piped to stdout (-movflags frag_keyframe+empty_moov+default_base_moof) so the HTTP handler can stream straight to the browser without disk I/O. Quality ladder: 480p (1.5Mb), 720p (3.5Mb), 1080p (6Mb), 2160p (25Mb). Default 1080p when unset / unknown. -ss seek for resume / scrubbing. - internal/streaming/hwaccel.go — DetectHWAccel runs `ffmpeg -encoders` once per process and caches the best available. Order: NVENC → QSV → VAAPI → VideoToolbox → libx264. VAAPI is the only family that wires up HW decode too (`-hwaccel vaapi`); the others software-decode and HW- encode (works fine and avoids /dev/dri permission rabbit holes). - internal/streaming/stream.go — Transcoder facade wires Analyze + Stream together for the API handler in Fase 4. Captures the last 8 KiB of ffmpeg stderr for diagnosable errors without unbounded memory. Tests (20 unit, all green): - AnalyzeCompatibility: h264+aac direct, video-only direct, HEVC → transcode, 10-bit HDR → transcode, EAC3 audio → transcode, nil guards - ResolveQuality: empty + unknown fallback to 1080p, 4-step ladder - BuildFFmpegArgs: direct play -c copy, transcode libx264 + bitrate + scale, NVENC swaps encoder & drops preset, VAAPI injects -hwaccel + scale_vaapi, -ss timestamp formatting - HWAccel: encoder-name table, VAAPI is the only one with HW decode - formatDuration: zero, sub-second, HH:MM:SS, negative-clamped - cappedBuffer: tail retention through multi-write and large-write paths - NewTranscoder: rejects empty paths --- internal/streaming/ffmpeg_args.go | 173 +++++++++++++++++ internal/streaming/hwaccel.go | 144 ++++++++++++++ internal/streaming/stream.go | 131 +++++++++++++ internal/streaming/transcoder.go | 135 +++++++++++++ internal/streaming/transcoder_test.go | 267 ++++++++++++++++++++++++++ 5 files changed, 850 insertions(+) create mode 100644 internal/streaming/ffmpeg_args.go create mode 100644 internal/streaming/hwaccel.go create mode 100644 internal/streaming/stream.go create mode 100644 internal/streaming/transcoder.go create mode 100644 internal/streaming/transcoder_test.go diff --git a/internal/streaming/ffmpeg_args.go b/internal/streaming/ffmpeg_args.go new file mode 100644 index 0000000..1869864 --- /dev/null +++ b/internal/streaming/ffmpeg_args.go @@ -0,0 +1,173 @@ +package streaming + +import ( + "fmt" + "strconv" + "time" +) + +// StreamOptions controls a single transcode/remux invocation. +type StreamOptions struct { + // Quality caps the output resolution and bitrate when transcoding. + // Direct play ignores it (the source bitrate wins).
