Background refresh runs when iOS chooses, and for this app that has
been rarely, so the icon's unread count lagged until the app was
opened (#421). Now ipx sends the count:
- ipx: a push_devices table and POST/DELETE /api/push/devices. With
[push] set to an APNs key, a task compares each phone's All
Subscriptions unread count with the last sent, once a minute, and
sends a changed one to Apple as a badge-only push: no alert, no
sound. A token Apple says is gone is forgotten. The signing token is
ES256 over the team and time, made again every forty minutes, inside
Apple's limits.
- iOS: the aps-environment entitlement. The app registers for push
once badge permission is given, each launch, and hands its token to
the page.
- Page: registers the token with ipx as the person signed in, since
the player's address (ipxapi) lets through only the player's paths,
and removes it on signing out.
jsonwebtoken here is built without PEM support, so the .p8 key's
base64 is decoded in push.rs rather than turning on a feature and
changing Cargo.lock for one file.
cargo test -p ipx on macOS: 182 pass; the 3 that fail read /proc and
fail there without this change too.
