Dispatch read one byte of the code, so a code with a non-zero high byte
was handled as its low byte. Message::get_message_code now reads the
whole little-endian uint32 and handlers register by u32. PeerInit and
PierceFirewall, the only frames with a one-byte code, get their own
accessor for the listener's first frame.
Running the e2e suite against a real soulfind showed the per-member slots
field was implemented backwards. The wire field is `slotsfull` -- a boolean
that is true when the member's upload slots are all occupied -- not a count
of free ones. `slots_free: u32` named it, documented it and printed it as
the opposite of what the server means, so a caller reading it would pick the
busiest peer to download from.
- types: `slots_full: bool`, with the wire name in the doc comment
- the DTO, the `room users` output and SKILL.md follow
- a new e2e test joins a room with a member sharing a known three files and
asserts the counts, the roster alignment and the slot flag against
soulfind, so the parsing is checked against a real server rather than only
against frames this repo wrote itself
The JoinRoom (code 14) reply carries, after the membership list, four
parallel vectors describing each member: status, share statistics, free
upload slots and country. The handler stopped after the usernames, so all of
it was discarded. It is now parsed and exposed as Client::room_member_stats.
Issue #48 asked for RoomStats (57) and RoomListStats (55). Those codes are
UserInterests and MyRecommendations in the Soulseek protocol; there is no
RoomStats message on the wire. Per-room user counts already arrive with
RoomList (64), which the client handles, and the per-member statistics are
part of the JoinRoom reply -- so that is where this adds them.
- join_room.rs: parse the stat vectors, each bounded by the payload so a
hostile count cannot hang or overallocate
- types::RoomUserStats; every field looked up positionally so a server
sending short vectors (or omitting countries) does not shift the roster
- ServerMessage/ClientOperation::RoomMemberStats and the context snapshot
behind Client::room_member_stats, replaced on each rejoin
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.
