free_port() hands out a port that is free when asked, not when soulfind
binds it, and soulfind exits when the port has gone. The library
harness also gave soulfind only five seconds and did not notice a child
that had died, so either read as "no soulfind server" and failed the
test. It now waits ten seconds like the CLI harness, never takes a
child that has exited as up, and retries on a fresh port; the CLI
harness gets the same retry.
A listener that takes the port first can still answer before soulfind
has got as far as binding, so the two library tests that bind listeners
outside the server gate now take it too: while a soulfind starts, no
other test in that binary binds anything.
Two daemon tests cancel a download that has to still be waiting, and both
waited on e2e_ghost_peer, a user who never logs in. That only ever worked
inside a timer: the download sat unconnected until the 20-second broker
timeout failed it, and the tests cancelled inside that window. Since
CantConnectToPeer ends the wait on downloads for a peer the server cannot
reach, soulfind answers the brokered dial straight away and the download
fails before the cancel lands. The CLI test failed on every daemon-mode run,
which is what blocked the v19.0.0 release; the protocol suite's twin only
passed because its cancel raced the server's answer and won.
Both now download from a silent peer: a raw login whose announced listener
accepts the connection and never replies, so the download stays queued the
way it does behind a busy peer, for as long as the test needs it.
The client read the distributed network but never carried it: a peer
dialling with a D connection was logged and dropped, and AcceptChildren
was hardcoded false, so this client took from the tree without ever
relaying a search for anyone else.
With accept_children set, peers hang from us: each is told where our
branch sits when it connects and again when the branch moves, every
search that reaches us is passed down, and a child that goes away loses
its slot. Ten at a time, matching Nicotine+, since each costs a socket
and a copy of the network's whole search stream — which is also why it is
opt-in, through the new accept_children config key (ignored without a
listener, since a child would have nothing to dial).
The TUI suite had grown its own copy of the soulfind spawner the protocol
suite already carried, and its own copy of the CLI suite's in-process
client and settle helpers. All four suites now spawn, log in, settle and
skip through `tests/common`: the CLI suite's own server goes too, and
the fixture checks its child is still alive before calling the port
answered, so a lost port cannot pass another server off as ours.
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.
