The level lived in a `static mut` read from every logging thread and
written by `init`, an unsynchronised access the compiler only tolerates
inside `unsafe`. It is an atomic now, read without `unsafe`, and a host
can raise or lower it while running through `set_log_level`.
Nothing in the repo said that pull requests go to develop rather than master,
or that release-plz reads the commit subject to pick the next version. Both
cost a first-time contributor a round trip.
CONTRIBUTING.md covers those, the three checks CI runs, and the fact that the
e2e suites skip without a soulfind server. The README and the community page
link to it, and it joins the footer's Project column.
An AdminMessage (server code 66) is how a server tells everyone it is
going down, and the client dropped it on the floor. It now arrives in
the private-message inbox as a message from the user "server", which is
also the name the server's own command replies already come from, so
every reader of that inbox shows it without a new API.
A browse or folder listing and a search reply went out as zlib "stored"
blocks, so a big share cost every browser its full uncompressed size,
and the inflater ignored the adler32 trailer, so corrupt data passed.
Listings now deflate through a fixed-Huffman encoder over an LZ77 match
finder, which shrinks a listing's repeated path prefixes to about a
tenth, and a stream whose trailer does not match is refused. No crate:
the encoder is a hundred lines beside the inflater it feeds, and the
inflater is named for what it does.
Answering a search lowercased every shared path again for every query:
with a large share and the steady stream of searches the server forwards,
that is an allocation per file per search. The lowercase key is now
computed once when the share is scanned.
Downloads read the peer socket 8 KiB at a time, eight syscalls where one
now does; the reference clients read 50 to 256 KiB. Progress was reported
every fifteen reads, a cadence that stops meaning anything once a read
can be anywhere from a few bytes to 64 KiB, so a report now lands every
128 KiB received instead: the same volume as before for a fast peer, and
a window wide enough for a slow peer's rate to mean something.
Progress assumed every read had filled the buffer, so a peer trickling
small chunks was reported at up to several times its real rate. The
rate now comes from the bytes received since the last report.
A NAT that drops an idle mapping leaves the server socket looking
connected while the server can no longer reach us, and nothing errors:
peers stop finding us and searches go unanswered until a restart. The
server socket now carries TCP keepalive (idle 10s, interval 2s, ten
probes), which keeps the mapping alive and turns a dead path into a read
error within about half a minute, as Nicotine+ does. The server stopped
answering ServerPing (code 32) long ago, so an application ping is no
substitute. Windows gets a no-op until the daemon ships there.
Opening a user's profile in SoulseekQt or Nicotine+ asks that peer
directly (peer code 15), and a peer that never answers shows an endless
spinner. The reply (code 16) carries no description or picture, the
configured upload slot count, how many uploads are waiting, and whether a
slot is free right now, which is what the reference clients send.
soulfind has reported the host's LAN address for a loopback login since
1eab2e8 (November 2025), so the client dials the mocks there and a
listener bound to 127.0.0.1 refuses it: every upload and most downloads
failed against a current soulfind while the e2e suite, whose mocks
already bind all interfaces, stayed green.
"Download folder" in SoulseekQt and Nicotine+ asks the sharer for that
one folder (peer code 36) instead of the whole share, and a sharer that
never answers leaves the folder download hanging. The requested folder
now comes back as a FolderContentsResponse (code 37), which carries a
directory listing in the same form a browse does, so the two share one
codec. The browse and folder replies also share one reply helper.
Every reply to a peer's search claimed a free upload slot, no speed and
an empty queue, whatever the sharer was doing, and searchers rank
sources on exactly those fields. A reply now says whether a slot is
free, the bytes per second of the last completed upload, and how many
uploads are waiting.
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.
A search token was the first five hex digits of the query's MD5, so two
queries could share one, and a peer's answer to either landed in whichever
search the map handed back first. Tokens now come from a counter, which
no two live searches can share.
The e2e test uses two queries that collide under the old scheme.
A broad query against a big share was answered with every match, so one
search could hand the whole index to a stranger, and every such search
did it again. A reply now carries at most MAX_SEARCH_REPLY_FILES (150,
Nicotine+'s default), which is more sources than any searcher scrolls
through.
The keys overlay scrolled with its own counter, a fixed page of ten and a
usize::MAX sentinel that the renderer clamped back; it now reads through
the same LogView as the chat and room logs, so the page is the window it
last drew and the half-page keys work there too.
One pane_area lookup and one page_of helper replace the pane-to-area match
that page_size, highlighted_name_end and the mouse hit test each repeated,
and list_jump takes its page as a usize so the callers stop converting.
The pane number keys are one range arm over FocusedPane::ALL, whose index
is the declaration order. The row layout carries each pane's weight beside
it instead of re-matching with an unreachable arm, and the help columns are
measured from the lines already built rather than built again for their
width. The shortcut legend borrows its static keys instead of allocating
three strings per entry per frame.
The sideways keys the results had (h/l, arrows, 0 and $) now scroll a
transfer's file name and a query too, each list on its own. The browse tree
and the room list take Home/End, PgUp/PgDn and the vim jumps like the main
lists, and a chat log, room or private, pages back through its history and
holds its place while new messages arrive; what arrives meanwhile counts as
unread until the reader returns to the end.
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.
Scrolled rows cost 31.7ms per frame at 30k results against 13.3ms on
develop, because every row segmented its whole filename into grapheme
clusters. Walk back from the end for at most one column of cells and
forward for at most the offset, so a row costs the column width rather
than the filename, and drop unicode-truncate for unicode-width. A tail
never starts on a combining mark.
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.
Closes#55.
While [2] Results is focused the Info pane describes the highlighted
result, so a truncated path can be read in full. h/l (or the arrow keys)
scroll the filename column by display cells, 0 and $ jump to either end
of the highlighted name, and Home/End, g/G, PgUp/PgDn and Ctrl-f/b/d/u
move through the list; the same keys work while a filter is being typed.
Ctrl chords are no longer read as their bare letter: outside [2] they do
nothing, where before Ctrl-d deleted a search and Ctrl-c opened rooms.
Space after a filter that matches nothing no longer indexes an empty
list.
