- fetchIpv4 builds its Response inside the https response callback, outside
the promise. A 204, 205 or 304, a status above 599 or an invalid reason
phrase made the Response constructor throw there, an uncaught exception
that stops the dev server. Null-body statuses now get a null body and
anything else that cannot become a Response rejects, as the Radio Browser
transport does.
- A non-OK FIRMS or mapkey-status response cancels its body so the IPv4
socket closes at once instead of at the deadline.
- Tests: the crash cases (fail on the old code), a source check that every
upstream request goes through fetchFirms and that fetchSource's body read
shares its deadline (fails if either call reverts to fetch), a real-fetch
contract test for the address-selection error shape, and an explicit skip
in the IPv4-only socket test where the host cannot tell the families apart.
- Changelog entry moves to changelog.d/1078-firms-ipv4-fallback.md per
CONTRIBUTING; CURRENT-STATE says which timeouts are retried and that the
retry does not follow redirects.
Resolve fetchSource onto main's shared deadline: one AbortSignal covers the
fetchFirms request and the capped body read. The CHANGELOG entry moves to a
changelog.d fragment in the next commit.
Node's network-family auto-selection gives each resolved address a short
attempt timeout. On hosts where IPv6 is unreachable, a slow IPv4 handshake
is abandoned for the IPv6 address, which fails at once, and the request
reports only `fetch failed`. Retry such failures once with a single IPv4
connection within the same deadline, and log the per-address connection
errors (never the keyed URL). Node 26 wraps the AggregateError one level
deeper, so both shapes are recognised.
Fixes#68
Route the six proxied fetches that still buffered upstream bodies without
a limit through the shared capped readers in src/sources/httpBody.js:
FIRMS CSV, CelesTrak TLE groups, adsb.lol /v2/mil (both the OK and
relayed-status paths), TomTom flow tiles, OpenSky states/all and adsbdb
enrichment lookups. Each cap is a bound sized well above the measured
payload, not a budget.
readResponseBytesCapped gains the same optional abort signal as the text
reader, with the same cancel-on-abort plumbing and reader release, so the
TomTom tile path can share the route deadline instead of reading
arrayBuffer() unbounded. Where a route already had a deadline, the same
signal now covers the body read as well as the headers. Two polls had no
deadline at all: the adsb.lol military poll gains a 12-second one and the
OpenSky states/all exchange, including its Basic-auth retry, a 20-second
one; both miss into their existing STALE paths.
FIRMS map-key status, the OpenSky token exchange and CCTV media are left
as they are.

Adds MODIS NRT to Active Fires and a keyless Fire Perimeters layer (NIFC WFIGS) with
InciWeb incident links, served through a capped, cached /api/fire-perimeters proxy.
