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)
- 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
