One popular search produced a ConnectToPeer for every responder, and
each one cost a 2 MiB wrapper thread, an unbounded 256 KiB actor, a
listener thread per inbound socket, and on failure a 2 MiB thread that
slept for 20 seconds. A container with a pids limit died on one album
search (issues #32, #33).
Four bounds, no behavior change for a quiet session:
- P-type registrations run inline on the ops loop; only F transfers
keep a worker thread. The dial already ran on the actor thread.
- The broker timeout is a deadline swept by the ops loop instead of a
sleeping thread per failed dial.
- The registry caps live actors (default 512, Client::set_max_peers).
At capacity the oldest peer outside the caller's protected set
(live downloads, uploads, pending serves, queued messages, browses
in flight) is evicted; if none qualify the registration is refused
before any thread is spawned.
- Concurrent listener handshakes are bounded by a 128-permit
semaphore released once the peer-init arrives, so slow handshakes
cannot multiply threads while transfers stay unthrottled.
A replayed TransferResponse for an InProgress or Completed token is
dropped instead of starting a second transfer thread over the same
.part file.
Fixes#32Fixes#33
An agent driving the binary could search, fetch and chat, but it could not be
a peer: nothing kept a session online to serve files, nothing reported an
upload, shares could only be set at startup, and there was no way to ask
whether a peer was worth queueing to or to check credentials without doing
something else.
New commands:
serve [--follow] stay online sharing; one record per upload
whoami credentials, connection and what we offer
user <NAME> a peer's presence and share counts
room users <ROOM> the member roster
shares list|add|remove|status|reindex
config path|list|get|set
`config` and `shares list|add|remove` need no account, so they run before the
credential check — asking a script to log in for a `config get` would be a
poor trade. `serve` is the only place uploads are visible: they live in the
process serving them, so a one-shot `uploads list` could print nothing but an
empty list.
Library additions, all request/poll pairs matching the existing conventions:
- Client::room_members, kept current from the join and leave events
- Client::request_user_info / user_info, backed by new handlers for
GetUserStatus (7) and GetUserStats (36) — codes the dispatcher previously
logged as unhandled. The wire format is taken from soulfind's own source
and pinned by an e2e test that asserts a peer's real share count.
- UserInfo carries presence and stats as Options, so a reply that never
arrived cannot be read as "offline" or "shares nothing"
- request_user_info clears the previous answer, so the documented poll loop
observes this request rather than the last one
- ServerMessage and ClientOperation are now #[non_exhaustive]: every protocol
message the client learns adds a variant, and that should not break callers
- the crate root and prelude re-export every type a Client method returns
Also pins the output contract with tests: under --json, stdout carries only
newline-delimited JSON across fifteen command shapes while progress still
goes to stderr, and a failing command writes nothing to stdout at all.
Client::set_shared_directories rescans the given roots into a fresh
in-memory index, swaps it for peers, and re-announces the folder/file
counts to the server. The current directory list moves into the client
context so the running set is queryable. e2e-verified: a browser sees a
directory that was added after login.
- remove 34 trivial restating comments (auto-fix)
- replace all 20 production .unwrap() calls with graceful handling:
?-propagation via LockPoisoned, unwrap_or_default on infallible
conversions, let _ = on actor-channel sends, and a downloads_sender()
helper in the TUI that also dedupes three channel-init blocks
- collapse nested if into match guard (clippy::collapsible_match)
- split client.rs (2275 lines) into a client/ module: connection,
search, downloads, uploads, rooms, operations
- split ui/main_tui.rs (2027 lines) into a main_tui/ module: render,
input, browse, rooms, downloads, search
- extract oversized functions: peer_actor/server_actor handle_message
into per-message helpers, main() into init_logging/run_default_tui,
download_selector and main_tui render into per-section helpers
Mechanical only, zero behavior change. Verified: clippy clean
(pedantic+nursery), fmt clean, 143 unit tests + 16 e2e tests against
soulfind pass, lint clean.
