Seven region audits, every finding adversarially verified against the
whole workspace before being applied; 80 landed and the two that failed
in application were refuted honestly (ParseError has a from_str_radix
producer the audit missed; NatPmpError's Display is the only reader of
its diagnostic payloads).
The bigger cuts:
- The NewPeer/PierceFireWall cluster: an operation variant nothing ever
sent, its 77-line arm, a protocol-wrong Client::pierce_firewall that
wrote a peer-init frame down the server socket, and the struct only
they used. The live paths in peer/listen.rs are untouched.
- The ops loop reads `for operation in reader` instead of hand-rolling
recv/break, de-indenting the whole dispatch body.
- Dead lib surface: Message::print_hex and four unused accessors,
UploadFailed, registry and actor getters, build_watch_user,
strip_ansi_codes, delegating shims on ClientContext. Removing public
items makes this a semver major, which the release pipeline enforces.
- Never-used flexibility: the state-migration framework that never held
a migration, border-type helpers that all answered Rounded, the TUI's
max_concurrent_downloads field nothing read.
- Convergence: six poll loops into poll_until, three wrap-around
navigation blocks into cycle, hit tests into Rect::contains, char
walkers into floor/ceil_char_boundary, five Download literals into
one helper, the suites' shared scaffolding into tests/common.
Deliberately not taken: swapping the hand-rolled zlib inflate and MD5
for crates (they replace wire-facing machinery whose tolerance of
real-world peer quirks no local test exercises) and pulling chrono into
the lib for a log timestamp. Recorded for their own decision.
Net -1002 lines. Both e2e modes stay green: 94 CLI tests each way, 16
protocol, 33 lib, unit suites, clippy pedantic clean, aislop 100/100
with the four scanner false positives suppressed inline where they
fire.
Adversarial review of the chat-rooms feature surfaced seven confirmed
issues; all fixed with regression tests:
lib (DoS hardening — a malicious/MITM server could send a tiny frame
with a ~4-billion element count):
- room_list: bound the name/count vector loops by remaining payload.
- join_room: bound the member-list loop the same way.
TUI (soulseek-rs/src/models/rooms.rs, ui):
- a message for a room we already left no longer resurrects its tab
(route via open_index, not ensure_open).
- closing a tab now clears the unread badge on the room we land on.
- a room-list refresh keeps the highlight on the same room across a
re-sort (track selection by name, not index).
- Esc in the room list clears a lingering filter before closing, matching
the title's 'Esc: clear' hint.
- chat log renders one row per line so the newest message is never
clipped by wrapping.
Implement the Soulseek chat-room server messages against soulfind's
wire format:
- MessageFactory builders: room-list request (64), join (14),
leave (15), say (13).
- Handlers parsing the server side: RoomList (64) names+counts,
JoinRoom (14) membership, SayChatroom (13), UserJoinedRoom (16),
UserLeftRoom (17), LeaveRoom (15).
- Surface everything to the client as a drained RoomEvent stream plus
a room-list snapshot; new Client API: request_room_list, join_room,
leave_room, say_in_room, room_list, take_room_events.
Unit tests cover each builder and handler; server-gated e2e tests
exercise message delivery and room listing against soulfind.
- Drop dead Rooms/Room infrastructure and the rooms field on Context.
- Remove unused ActorMessage::Tick variant and the now-empty handler arm.
- Strip dead active-thread tracking machinery from ThreadPool (unused
getters, _id/_active_threads/_total_threads parameters).
- Flatten ServerActor::initiate_connection: the duplicated retry block
was a copy-paste retry against the same address with the same args
and could never succeed where the first attempt failed.
- Delete commented-out print_hex2/decode debug stubs, dead test
fixtures in login.rs and message_user.rs, the 47-line commented body
of RoomListHandler, and assorted // TODO theater.
