Implement the DIRECT connection-initiation mode so a download can target a
peer the client is not already connected to:
- Fix the outbound peer handshake. on_connection_established sent
build_watch_user() (a server WatchUser message, wrongly framed with
get_data()) for outbound connections; it now sends a proper length-prefixed
PeerInit (peer code 1) with our own username. own_username is plumbed in
via PeerRegistry -> PeerActor; inbound peers (outbound=false) are unchanged.
- download() now auto-connects: if there is no control connection to the peer
it sends GetPeerAddress and defers the QueueUpload until the outbound stream
handshakes, signalled by a new ClientOperation::PeerConnected. A never-
connected client still resolves the download to Failed (unit test).
- Add Client::connect_peer(username) to open/pre-warm a control connection.
Verified end to end against soulfind: a_file_downloads_from_a_peer_via_direct_connection
logs a mock peer into the server, advertises its port via SetWaitPort, and the
client resolves the address, dials it, and downloads the file — bytes match.
The F-serve leg is shared with the passive-download mock.
Enable the full clippy all + pedantic + nursery groups as workspace warnings,
with a small documented allow-list for the pedantic/nursery lints this project
intentionally does not follow (rustdoc-style requirements, deliberate numeric
casts in the protocol/UI layers, and a few noisy nursery lints). Also enable
the rust unused_lifetimes and unsafe_op_in_unsafe_fn lints.
Fixed every resulting warning (527 -> 0) mechanically per clippy's suggestions:
inline format args, const fns, item ordering, let-else, redundant clones,
map_or, cast_lossless, Eq derives, associated-fn conversions for methods that
never used self, and removing unnecessary Result wrappers whose call sites could
never propagate an error. No runtime behavior changed; cargo fmt applied.
cargo clippy --workspace --all-targets: 0 warnings. All tests pass.
Splits the downloads area 60/40 with a new info pane that adapts to the
selected download's status: header (filename, user, size, status, save
path, bitrate, length) plus queued-specific fields (queue position, peer
slots, peer upload speed) or live progress/speed/ETA when transferring.
Plumbs queue position via a new ClientOperation::PlaceInQueueUpdate so
PlaceInQueueResponse messages from peers reach DownloadStore, and threads
search-time metadata (bitrate, length, peer slots/speed) onto Download
through a new download_with_metadata entry point.
Add SoulseekRs::LockPoisoned variant and a small RwLockExt/MutexExt
helper module exposing read_safe/write_safe/lock_safe that map
PoisonError to that variant. Walk every non-test lock acquisition
across client, peer/server actors, peer registry, listener and the
thread pool: propagate via ? where the function returns Result, log
and degrade to a sensible default (return early, false, None, empty)
where it does not. Client::connect now returns Result so the CLI can
surface the failure instead of panicking.
