Debrid downloads to a network mount (the prod download dir is an NFS share
at /mnt/nas/peliculas) could fail verification with "size mismatch:
expected N, got M" where the file on disk was smaller than the bytes
streamed. Every Write() succeeded into the client page cache (progress
reached 100%) but the function returned before the asynchronous write-back
to the NAS completed, so the caller's verify() stat'd a half-flushed file
and rejected it. Concurrent downloads to the same mount made the contention
worse; a lone retry succeeded because there was no flush pressure.
- fsync the file (file.Sync) and check the error before reporting success,
so a write-back failure surfaces here instead of silently truncating.
- Stop swallowing the file.Close() error via a guarded close: error paths
still clean up through defer, the success path closes explicitly and
inspects the error.
- Guard against a premature end-of-stream (downloaded < Content-Length).
- Safety-net re-stat after the flush: if the on-disk size is short, remove
the corrupt partial and return a retryable error. This is also the only
integrity check when the server sends no Content-Length.
Add TestDebridDownloadTruncatedStream.
CheckDiskSpace (internal/engine/diskspace.go) refuses a download before
writing when its expected size wouldn't leave a configurable reserve free,
so a download never fills the filesystem to 0 mid-write (which corrupts the
partial file). Wired into all three downloaders ahead of any write — torrent
(DataDir), debrid (outputDir, resume-aware), usenet (outputDir, fresh only).
Reserve from downloads.min_free_disk_mb (default 2048 MiB) via SetMinFreeBytes.
The manager treats an InsufficientDiskError as terminal — no source fallback,
since another source would fill the same disk — and surfaces the clear message.
Best-effort: unknown size or a stat failure doesn't block (ENOSPC stays the
backstop). Also hardens formatBytes against an exabyte-scale out-of-bounds panic.
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)
- Expand default trackers from 5 to 31 (synced with web tracker-list.ts)
- Add DHT node persistence between sessions (~/.local/share/unarr/dht-nodes.txt)
Saves known nodes on shutdown, restores on startup for warm DHT bootstrap
- Make metadata_timeout and stall_timeout configurable in config.toml
Default: 0 (unlimited, like qBittorrent) — users can set custom values
- Fix CleanTitle to handle web domains and format patterns (e.g. pctfenix.com)
- Consolidate 3 maps (active, taskDirs, taskTrackers) into single
activeDownload struct — eliminates out-of-sync state on mid-function panic
- Cancel() runs os.RemoveAll in background goroutine (non-blocking)
- Flush(): clear dirty before unlock to prevent concurrent flush race on
same tmp file; remove fragile re-mark-on-error pattern
- Revert RWMutex → Mutex in ProgressTracker (negligible benefit under
write-heavy workload, higher overhead)
- Remove file.Sync() from debrid and usenet downloaders (Close flushes
kernel buffers; fsync blocks for seconds on large files)
- Pin golangci-lint to v2.1.6 in CI (was floating with `latest`)
- Fix CI matrix: Go 1.25+1.26 (was 1.24+1.25, but go.mod requires 1.25)
- 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
DebridDownloader receives directUrl from the server and downloads via
plain HTTPS with progress reporting, resume (Range), and pause/cancel.
- Add DirectURL, DirectFileName to agent Task and engine Task types
- Implement DebridDownloader: HTTPS download with progress, resume, cancel
- HTTP client with 30s ResponseHeaderTimeout
- Safe shortID helper to prevent slice panic on short IDs
- Validate 416 against Content-Range server size for resume integrity
- Register debridDl in daemon and one-shot download command
- Tests: available, download, resume, cancel, pause, fallback filename,
expired URL (410), unauthorized (401), shutdown, task propagation
