New next/kernel/peer_actors.erl is the federation-side cache for
{PeerActorId, PeerActorState} entries. PeerAS is exactly the shape
envelope:verify_signature/2 reads (proplist with :public_keys), so
the inbox handler can pipe the cache hit straight into
pipeline:validate_inbound/3 from Step 5b.
Pure-functional API:
new/0
lookup/2(PeerId, State) -> {ok, PeerAS} | not_found
store/3(PeerId, PeerAS, State) -> NewState
evict/2(PeerId, State) -> NewState
peers/1(State) -> [PeerId]
lookup_or_fetch/3(PeerId, FetchFn, State)
-> {ok, PeerAS, NewState} cache hit returns unchanged State,
miss stores FetchFn result.
| {error, Reason, State} FetchFn failure preserves cache.
| {error, {bad_fetch_return, X}, State}
FetchFn contract: (PeerId) -> {ok, PeerAS} | {error, Reason}.
Failed fetches do NOT poison the cache so callers can retry on
transient HTTP failures.
gen_server wrapper (registered name peer_actors):
start_link/0,1 start_link/1 accepts initial proplist for fixtures
stop/0
lookup_srv/1
store_srv/2
lookup_or_fetch_srv/2
peers_srv/0
evict_srv/1
handle_call dispatches mirror the pure-fn paths exactly.
The actual HTTP-GET fetch implementation (peer's actor doc -> peer
AS proplist) is Step 5d's responsibility — for 5c, FetchFn is just
the contract callers fill in.
19/19 in next/tests/peer_actors.sh:
- new/0 -> []
- lookup miss -> not_found
- store + lookup round-trip
- peers/1 in insertion order
- evict + evict-unknown no-op
- lookup_or_fetch miss invokes FetchFn, hits cache after
- lookup_or_fetch hit skips FetchFn (verified by tombstone fn)
- fetch error preserves cache state
- bad fetch return shape captured
- gen_server start_link + miss/hit/fetch/evict round-trips
- start_link/1 pre-populates cache from initial state
