"""ProxMenux-managed installs registry.
|
|
|
|
Single source of truth for "things ProxMenux installed (or detected as
|
|
already installed) and can check for updates on". Replaces the
|
|
type-specific polling we had before — every check now flows through
|
|
this module, so adding a new tracked install (Coral driver, Frigate,
|
|
etc.) is one entry in DETECTORS + one entry in CHECKERS.
|
|
|
|
Two operation modes:
|
|
|
|
* **Detection** — at AppImage startup and every 24h, every registered
|
|
``DETECTOR`` runs against the host. If the probe finds the thing
|
|
installed and it's not in the registry, we add it (with
|
|
``installed_by="detected"`` so the operator sees we autodiscovered
|
|
it). If it's in the registry but the probe fails, we mark it
|
|
``removed_at`` instead of deleting — keeps history and avoids
|
|
spurious notifications when a probe transiently fails.
|
|
|
|
* **Update check** — for every active entry, the matching ``CHECKER``
|
|
runs and updates ``current_version`` + ``available`` + ``latest``.
|
|
Each checker is responsible for its own per-source cache (the
|
|
Tailscale OCI checker memoises for 24h, NVIDIA for 7 days). The
|
|
notification poll loop reads the registry, emits a notification when
|
|
``available`` flips false→true for a (type, latest) pair it hasn't
|
|
notified yet.
|
|
|
|
Persistence is a single JSON file at
|
|
``/usr/local/share/proxmenux/managed_installs.json``. Atomic writes
|
|
via tmp+rename so a crash mid-write can't leave a half-written file.
|
|
|
|
The module is concurrency-safe: a single ``threading.RLock`` guards
|
|
every read-modify-write so the periodic detector and a request handler
|
|
calling ``get_registry()`` can run in parallel without stepping on
|
|
each other.
