The results pane now has the whole width, where a long file name needs it,
and Searches, Downloads and Info share the row underneath. Tab and Shift-Tab
walk the panes, z zooms the focused one to the window, w hides it so the
others widen, and its number brings it back. Every list takes the same
navigation keys, the shortcuts bar wraps instead of cutting keys off, and ?
lists every key by pane, scrolling on a short terminal.
Follows up on #55.
Closes#54.
A download can now be cancelled whether it is queued, in progress, or
paused. Cancelled is a terminal status: the store refuses to overwrite
it, the status channel relays nothing after it, the partial file is
deleted, and the transfer thread releases its socket at its next
one-second poll instead of the 30s read deadline. A queued download that
is cancelled declines the peer's later offer with TransferResponse
"Cancelled", and an inbound file connection for it is refused. A fresh
download of the same file evicts the dead row so it is not shadowed,
and a cancelled transfer is not re-queued after a restart.
Surfaces: Client::cancel_download, download.cancel over RPC, `transfer
cancel <user> <path>` on the CLI (which also stops an upload by that
name), and x in the transfers pane, where d dismisses the row.
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.
The cursor row set a foreground, and ratatui only skips a cell's colour
when that field is None — so selecting a row repainted its gold sizes,
blue usernames and status glyphs into one flat cream. Table cursors now
tint the background only, over a warm oxide wash instead of neutral.
Browse files, their sizes and the settings popup rendered in the raw
terminal foreground; they take the palette now, and free slots read
green when a peer has one.
Replace the ANSI Light* palette with the design system's tokens
(tokens/colors.css): oxide accent, phosphor focus, tape/signal/alarm
semantics, paper text on dust chrome. Only foregrounds and the row
highlight are painted so the user's terminal background shows through.
Route every bordered pane through a single pane_block() helper carrying
one column of horizontal padding, and give legends a consistent
[n] Title form with the tag in signal. The command bar now derives its
cursor position from the block's inner rect instead of a hardcoded
border offset.
Also collapses the download-status glyph match that was duplicated
across three render sites into download_status_glyph().
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.
