plugins declare the host binaries they need, and the installer checks
Offscale was self-sufficient. Music is not — it shells out to ffmpeg and ffprobe — and the way it fails without them is the reason this is a check rather than a line in a README. It does not fail. Missing ffprobe means the indexer catches the spawn error and returns a track carrying its filename and nothing else: no title, artist, album, duration or embedded lyrics. It then walks the whole library, writes a complete cache tree and reports success. Five swallowed catches, no log, no counter, and the only tell is coversSaved: 0 in a report nobody reads. So `osDependencies` is a manifest field: the binary to probe on PATH, why it is needed, and a package name per package manager. The shape is taken from scripts/setup-old/setup.sh rather than invented — probe the binary, case on $PM — and the names are per-manager rather than canonical-with-overrides because lib/packages.sh already recorded why that indirection was rejected. Probing the binary is what makes "built-in on this OS" free: on PATH means the package map is never consulted. Four decisions worth naming. Missing and uninstallable REFUSES the install, first, before a table is created or a row written — so there is nothing to undo, and the alternative is a plugin that installs, answers 200 and quietly produces nothing. The status is on GET /api/plugins and rendered before the button, because the owner is deciding whether to let the server run a package manager as root and that needs answering first. Installing by hand and watching it flip to present is the escape hatch on a machine without passwordless sudo. Package names get a deliberately narrow regex and reach Bun.spawn as an argv ARRAY, never a shell. Both halves are load-bearing: the regex means a metacharacter cannot get there, argv means it would be an argument rather than syntax if it did. Narrower than package managers actually accept — no `:`, no `+` version pins — because a plugin needing one wants a conversation. Success is OBSERVED, not inferred: after installing, the binaries are re-probed. A package manager exiting 0 having installed something that does not provide the binary is exactly the failure this exists to catch. installCommand mirrors lib/packages.sh's pkg_install_now exactly, including apt's non-interactive environment, so there is one definition of "install a package" rather than two that drift. sudo always gets -n: under PM2 a password prompt is not a slow path, it is a hang. brew never escalates. Verified live. ffmpeg and ffprobe were absent on this machine all evening; the page showed both missing with the exact root command, the install streamed `dependencies: installing ffmpeg with apt` then `ffprobe, ffmpeg now on PATH`, and X-Audio-Duration appeared on a stream response for the first time. The refusal path was exercised against a temporary probe dependency: HTTP 400, steps: [], reason named. THIS CHANGED THE MACHINE: ffmpeg 6.1.1-3ubuntu5 is now installed via apt. Found on the way: a manifest is read once per process. Discovery does `await import()` and the module cache holds it, so editing a manifest changes nothing until pm2 restart officer — including `outdated`. Cost ten minutes and is now in the runbook. bunx tsgo clean. 797 tests, 787 pass, 7 fail — the same seven, +25 new. |
