Smart URL actions: multi-step browser automation for web cells behind
login pages. Steps: navigate, fill (form fields), click, wait, wait_for
(element selector), javascript (raw eval). Passwords in fill steps
encrypted with per-kiosk key for transport.
Schema: server/src/schemas/wire/smart-url.ts defines step types.
Stored in layout_cells.options.smart_url (no migration needed).
Bundle: includes smart_url config per cell. Fill step values encrypted
at bundle generation time with per-kiosk key (or cluster key fallback).
Kiosk: execute_smart_url_steps() builds an async JS sequence from the
steps and injects via WebKit evaluate_javascript on LoadEvent::Finished.
Supports session expiry detection via login_detect_url.
Admin UI: step builder TODO (currently configure via cell options JSON).
Data model + kiosk execution + bundle transport are complete.
Three bugs:
1. std::mem::forget(generation) leaked the Arc → old threads never
stopped on bundle reload. Now stored in a static Mutex; new start()
replaces it → old Arc drops → old Weak::upgrade() returns None.
2. CreatePullPoint Address uses namespace prefix (wsa5:Address,
a:Address, etc.). Parser only matched plain <Address>. New
extract_tag_ns tries common prefixes + fallback regex scan.
Also validates address starts with "http" and logs response
preview on failure for debugging.
3. Pull failure → immediate resubscribe with no delay → hammers camera.
Added 15s backoff after pull failure before resubscribe.
Full ONVIF event management overhaul:
DB: cameras gain event_source (auto|server|kiosk:<id>), event_sink
(auto|server|kiosk:<id>), and supported_event_topics (JSON array).
Server:
- GetEventProperties SOAP call in onvif.ts — queries camera for all
supported event topics (motion, ANPR, line crossing, etc.)
- POST /admin/cameras/:id/refresh-events route — runs GetEventProperties
via designated event source (kiosk WS relay or server direct)
- Camera edit form: event_source + event_sink dropdowns
- Camera detail: supported event topics table with refresh button
- Bundle includes event_source + event_sink so kiosk knows its role
Kiosk:
- onvif_events.rs respects event_source: only subscribes when "auto"
or "kiosk:<this_id>", skips when "server"
- Subscription status tracking: state (subscribing/active/failed),
last_event_at, error — reported in heartbeat for admin visibility
- BundleCamera gains event_source + event_sink fields
Auto logic for source: camera in kiosk's bundle → kiosk subscribes.
Auto logic for sink: TODO — same-subnet detection for WSBaseNotification.
Currently PullPoint only; push model is the next step.
Root cause: kiosk never stored cluster_key from pairing response.
Bundle ships onvif_password_encrypted (AES-256-GCM with cluster key).
decrypt_cluster was a stub returning None → empty password → WSSE auth
fails → CreatePullPoint rejected → no events ever.
Fix:
1. ClaimResp now includes cluster_key field
2. Stored encrypted at rest alongside kiosk_key (at_rest.rs)
3. Loaded at bundle render, passed to onvif_events::start()
4. decrypt_cluster implements full AES-256-GCM: parse v1.<iv>.<tag>.<ct>
format, base64url decode, decrypt with cluster key
Also: removed BF_ENABLE_ONVIF_EVENTS env gate — if camera is type=onvif
with onvif_host, subscribe. Gate was redundant with the type filter.
Also: bump Angie proxy_read_timeout to 600s on /api/admin/ for OS
bundle import (downloads ~1GB from GitHub, was timing out at 60s).
NOTE: existing paired kiosks won't have cluster_key stored. They need
to re-pair (delete + re-add) to receive it. New pairings get it
automatically.
New kiosk/src/onvif_events.rs: for each ONVIF camera in the bundle,
creates a PullPoint subscription, polls every 3s, parses
NotificationMessage XML into structured JSON (topic + source key/values
+ data key/values + timestamp), and POSTs to /api/kiosk/event with
source_type=onvif + camera_id.
Forwards ALL event topics: motion, ANPR (LicensePlateRecognition),
line crossing, intrusion, digital input, analytics, tamper — everything
the camera exposes. Node-RED sorts what matters.
Subscription lifecycle:
- CreatePullPointSubscription with 60s InitialTerminationTime
- Renew every 55s before timeout
- Unsubscribe on bundle change / shutdown
- Auto-resubscribe on pull/renew failure (30s backoff)
- Generation tracking via Weak<()> so old workers self-terminate
when start() is called with a new bundle
WSSE PasswordDigest auth for SOAP calls — same scheme the server's
onvif.ts uses. sha1 crate added.
BundleCamera extended with onvif_host/port/username/password_encrypted
fields (server already ships them; kiosk just wasn't deserializing).
Gated by BF_ENABLE_ONVIF_EVENTS=1. Enabled by default in the pi-gen
image env file.
TODO: cluster-key-based decryption of onvif_password_encrypted. For
now relies on the RTSP URI having plaintext credentials embedded (which
the ONVIF import path already ensures via rtspWithCredentials).
