fed-sx-m2: Step 8f — live HTTP delivery dispatch (+ 10 tests)
Test, Build, and Deploy / test-build-deploy (push) Failing after 36s
Closes Step 8 (except 8b-timer which still gates on Blockers #3
send_after). New next/kernel/dispatch_http.erl wires the BIF
landed in Step 8e into a delivery_worker-shaped dispatch_fn.
dispatch_http API:
make_dispatch_fn(PeerId, Cfg) -> fun((Activity) -> ok | {error,_})
dispatch(Url, Activity, Cfg) -> ok | {error, _}
inbox_url(BaseUrl, PeerAtom) -> <Base>/actors/<peer>/inbox
resolve_peer_url(PeerId, Cfg) -> {ok, Base} | {error, no_peer_url}
content_type/0 -> <<"application/vnd.fed-sx.activity">>
Peer URL resolution composes:
{peer_url, [{PeerId, BaseUrl}, ...]} static map (tests)
{peer_url_fn, fun ((PeerId) -> {ok, Url} | not_found)} closure
(Step 10c peer_actors)
Result mapping at dispatch/3:
2xx -> ok (worker drops the entry)
non-2xx -> {error, {status, N}} (worker bumps attempt)
resolver miss -> {error, no_peer_url}
transport -> {error, Reason} (BIF re-raises, caught here)
httpc:request/4 BIF wrapper updated to catch host Eval_error via
SX `guard` and re-raise as Erlang `error:{network, ReasonBinary}`
so callers can handle it through standard try/catch — previously
the host exception bubbled past the Erlang try/catch surface
(which only handles er-thrown? / er-errored? / er-exited? markers).
Subtle Erlang-port note documented in dispatch/3: this port's
try/catch requires a literal class atom (`error:Reason`); the
generic `Class:Reason` syntax is not supported. dispatch_http
catches `error:Reason` only, which is what the BIF re-raise
produces.
Test: next/tests/dispatch_http.sh 10/10 against background
python3 http.server (always-200 handler):
- module loads
- inbox_url builds /actors/X/inbox
- static :peer_url map resolves
- missing peer -> {error, no_peer_url}
- live POST -> 200 -> ok
- closure path -> ok
- closure on missing peer -> {error, no_peer_url}
- closed port -> {error, _}
- delivery_worker drains the queue via the live closure
- :peer_url_fn closure path resolves
No-regression gates green: Erlang conformance 761/761,
httpc_request 10/10, http_listen_bif 5/5, delivery_worker 17/17,
delivery_retry 11/11, delivery_dispatch 7/7.
