#1308 moved /api/overpass to the keyless cross-site gate: foreign origins
and cross-site fetches are still refused, but forwarding headers are not,
so the map works behind a reverse proxy. Voice place search spends the same
operator Overpass, so it now uses the same gate; with the stricter one,
place search failed behind a proxy while the map kept working. The prompt
lint note records the merged size, 55,370 with an operator Overpass.
From review:
- /api/osm/features now refuses cross-site browser requests like the other
quota-bearing routes, so a page elsewhere cannot spend the operator's
Overpass. SECURITY.md lists the route, its limits and its disk cache.
- One client runs one search at a time and two run at once in all, instead
of one global slot any single client could hold.
- A search gets 45 s across every configured endpoint in turn, answered 504
when it runs out.
- A cache write no longer waits on the disk prune; prune() waits until the
cache is idle for callers that need it.
The /api/osm/features cache key was the query alone, kept for a day, so after
an operator repointed OVERPASS_UPSTREAMS the old instance's answers were still
served. The key now includes the configured-upstream tag, as main's other
Overpass caches check it, so a new instance is always asked.
- turn named places and mapped landmarks into reusable bounded areas
- count loaded records inside resolved, drawn and annotated geometry
- find recent imagery for an area, the view or the pointer snapshot
- keep osm place search behind an operator-configured overpass endpoint
- preserve cancellation, ownership and follow-up memory across every action
- cover geometry, provider lifecycle, cache isolation and voice routing
