Debug output goes to the log file, so a site that fires per received message
or per retry lets someone else decide how much a machine writes to disk. The
WebRTC work added the first such sites.
- KCP io loop: absorbing ICMP errors as packet loss made a broken socket write
~100 lines a second for the 60s until the pong timeout reaps it. Log by run
instead: one line when a run starts, one per ~5s while it persists so a stuck
socket stays visible, and one on recovery with the total.
- punch_udp: the recv error retries every 10ms for up to MAX_TIME, so one line
per occurrence wrote thousands per punch. Log the first, report the count in
the timeout message.
- ICE candidate paths (client, mediator): the peer sets the candidate rate and
the rendezvous route carrying them needs no prior punch, so throttle to one
line a minute each with the suppressed count.

Candidates arrive in gathering order — host, then srflx, then relay — so a
full buffer was discarding exactly the ones that traverse NAT while keeping
host ones that only work on a shared LAN. Evict from the front instead.
Also document why the controller's ICE bridge must not reconnect on error, in
contrast to the controlled side's per-candidate retry: its socket address is
the return route itself (mangled into PunchHole.socket_addr, echoed back in
IceCandidate.socket_addr, resolved through tcp_punch), so a reconnect would
arrive from an address no route points at, and the server drops the old entry
when the connection closes. Once it dies both directions are dead, and
abandoning WebRTC is the correct response rather than retrying.

race_transports_prefer_webrtc committed any success from its first argument
outright, on the assumption that it is the WebRTC connect. It is not: the call
site passes a whole punch attempt, which internally falls back to request_relay
when its direct transports fail. That relay was therefore committed instantly
while the offer-less fallback's TCP punch was still in flight — inverting the
preference this function exists to enforce, since the is_p2p predicate the
caller already supplies was applied only to the `others` branch.
Apply it to both branches: a direct result from either side still commits
immediately, and a relayed result from either side is held for the window so
the other side can land something direct. Also commit a held connection when
the surviving branch errors, which the previous code only did on the first
branch's failure path.

The rebase onto master (switch-code feature) added an 8th request_relay
parameter; pass the interface's switch code from both WebRTC->relay
fallback paths so a role-swap session survives the fallback. Also drop

- treat ICMP-driven UDP socket errors (WSAECONNRESET 10054 on Windows,
ECONNREFUSED on Linux) as packet loss in punch_udp and the KCP pump
instead of tearing the session down; KCP retransmits through them and a
truly dead link is still reaped by the pong/app-level timeouts
- resolve STUN hostnames via tokio::net::lookup_host so DNS never blocks a
runtime worker; fix the inverted non-IPv4 error message
- add enable-kcp-congestion-control option (default on): switch the turbo
profile to nc=0 so brief loss on constrained links no longer spirals into
stalls; sender-side only, no wire negotiation
- pin kcp-sys to the rustdesk-patches branch: upstream main lost the
RustDesk patches on the EasyTier sync, and this branch also wires

- the WebRTC offer now rides any punch request; only an offer-less request
may close and reuse the rendezvous socket for TCP punching
(request_allows_tcp_punch replaces the udp_port-based invariant), with a
separate offer-less request racing as the TCP fallback
- WebSocket mode no longer disables WebRTC — ws only tunnels the
signaling/relay legs while ICE stays the only P2P path there; SOCKS proxy
still disables it (ICE would bypass the proxy and leak the real IP)
- controlled side: WebRTC-only punch replies and trickled ICE candidates go
over dedicated TCP connections to the rendezvous server instead of the UDP
mediator channel, for ws/TCP-only hbbs deployments; drop the now-redundant
rz_sender plumbing and the 400ms candidate re-send on that leg
- guard is_udp handling against responses to requests that advertised no
udp_port; skip the IPv6 socket bind under force-relay
- test_udp_uat: drop the STUN port race — the punch port must come from the
rendezvous server's TestNatResponse observing this socket's mapping, a
STUN probe from another socket can advertise an unreachable port

* feat(clipboard): optionally sync clipboard between connected sessions
Clipboard content received from a remote session is written to the local
clipboard with an owner marker, so the client clipboard loop deliberately
skips re-broadcasting it to avoid echo loops. As a result, text copied in
one remote window could not be pasted in another connected remote window.
Add an opt-in local option (allow-sync-clipboard-between-sessions) that
relays Clipboard/MultiClipboards messages received from one session to
all other connected sessions, excluding the source session. Per-session
clipboard permissions and view-only mode are still respected via the
existing send path, and the owner marker on the receiving peers prevents
any echo back.
Desktop (flutter) only; file clipboard is not affected.
* fix(lang): propagate sync-clipboard-between-sessions-tip to all locale files
Add the new key to template.rs and every locale file per the localization
convention, move the en.rs entry to the end of the list, and drop comments
that only restated the names next to them.
* fix(lang): add the 'Sync clipboard between sessions' label to the localization catalog
The checkbox label goes through translate(), so add it to template.rs
and every locale file so non-English locales can translate it. en.rs is
skipped since the English display text is identical to the key.
* fix(clipboard): check the source session's full clipboard permission before relaying
The relay was gated only by the incoming clipboard_allowed check
(!disable_clipboard && !view_only). Gate it with
is_text_clipboard_required() instead, which additionally respects the
source session's server_clipboard_enabled and server_keyboard_enabled
state, matching the predicate already applied to destination sessions.
A message arriving after the source permission was revoked (or from a
non-conforming peer) is no longer propagated to other sessions. The
existing local update_clipboard behavior is unchanged.
* fix(lang): translate the new clipboard sync entries in all locale files
Fill the 'Sync clipboard between sessions' label and its tooltip in
every locale file instead of leaving them blank, following each file's
existing terminology. template.rs keeps the empty master entries.

* perf(linux): stop the service loop from forking a shell per environment variable
The service loop re-derives the desktop every 500 ms, and every lookup on that
path forks. A healthy GNOME session spends ~104 process spawns a second, 8 full
`ps -u <uid>` scans and 2 full `ps aux` scans, to re-answer a question whose
answer has not changed. `get_env` alone is a `sh -c` pipeline of ~12 processes
per variable.
`get_envs` already reads `/proc` directly and was documented as the intended
replacement, so move the remaining `get_env` callers to it and delete it. The
xwayland probe drops from 4 pipelines (~48 processes) to one `/proc` walk, and
the pathological walk that #15952 was about drops from ~2900 processes to at
most 60 `/proc` walks. `get_cm` and `is_xwayland_running` read `/proc` instead
of forking `ps aux` and `pgrep -a`; `get_cm` also called `current_exe()` once
per line of `ps` output.
Selection semantics are preserved where they were load-bearing:
* `get_envs_of_newest` reproduces the `ps ... | tail -1` the removed pipelines
used, so a variable the newest matching process does not have means moving on
to the next pattern, never on to an older process that may belong to a session
which has since logged out.
* `get_envs` keeps its own order (readdir) and its all-process ranking, so the
existing `get_display_xauth_wayland` caller is unaffected. Only its handling
of an exported-but-empty value changes: `DISPLAY=` no longer counts as found,
where it used to satisfy a single-name query and return the empty value before
a process holding a real one was examined.
* `get_envs_where` lets the caller state what a complete answer is. Ranking by
how many of the requested names a process carries cannot know that `DISPLAY`
is mandatory and the rest interchangeable, so it could rank a process holding
three optional values above the one holding the pair that matters.
`is_xwayland_running` is scoped to the session's uid. The compositor starts
Xwayland as the session user, so another user's Xwayland -- a switched-away
session, a second seat -- used to route a pure-Wayland session into the Xwayland
probe, which has no display for it to find there.
Not addressed: this discovery path has never had any notion of the active
session, and filters by uid alone. Constraining candidates to the active session
is not possible for the most important one, since `xdg-desktop-portal` and its
backends run under `user@<uid>.service`, which spans sessions and carries no
`XDG_SESSION_ID`, no session cgroup and no audit sessionid.

* fix(linux): the newest-process walk must not answer with a grep or an older PID
Three findings from review of the commit before this one.
`/proc/<pid>/environ` failing to read left the walk on to the next PID, which in
`newest_first` mode is an older process -- possibly of a session that has since
logged out -- where the `ps ... | tail -1` pipeline this replaces stopped at the
one PID it had already picked. A read that fails is a process carrying none of
the requested names, not a process to skip. The `seen` latch that was meant to
hold the newest process is deleted: `accept` is reached once per matching
process, so returning on the first is what it already did.
The regex is matched against the whole `/proc/<pid>/cmdline`, where the pipeline
had a `grep -v 'grep'`. A user running `grep Xwayland` is otherwise the newest
match for that pattern and answers with whatever environment their shell had --
an X forwarding endpoint over ssh, say. This is the one place the walk still
differs from the `get_envs` it grew out of, which never had that filter and
could take an ssh `grep` over the portal it was looking for.
`get_envs` is left exactly as it was. Its completeness test was every requested
name *present*; stating it through `accept` turned it into every name *non-empty*
and, with the empty-value change that went with it, moved which process the
existing `get_display_xauth_wayland` caller settles on. `accept` is now told the
count and asks the question the loop it replaced asked. This supersedes the
`get_envs` bullet of the previous commit message: an exported-but-empty value
counts as found again, as it always did.

Pick up rustdesk-org/rustdesk_desktop_multi_window#37, which re-arms the existing bounded redraw timer whenever a secondary window is shown, including when its first frame was generated while hidden but not presented.
This may perform one delayed child refresh on each show. It intentionally does not add a presentation-complete flag: Flutter reports frame generation rather than successful presentation, so recording success after a synthetic refresh could suppress later self-recovery without a reliable success signal.
Fixes#15952.
Hyprland runs Xwayland without exporting `XAUTHORITY`, and
`get_display_xauth_xwayland` only returns once it has both `DISPLAY` and
`XAUTHORITY`. On such a session that condition is never met, so every refresh
runs the retry loop to the end: 10 rounds x 6 process patterns x 4 variables =
240 `get_env` calls, each a `sh -c` pipeline of ~12 processes starting with a
full `ps -u <uid> -f`. That is ~2900 fork/exec per refresh, and the service loop
repeats every 500 ms. The reporter measured a full core on a low-end laptop and
~60% of a core on a 13600KF.
The Wayland side answers for such a session, so accept `DISPLAY` together with
either `XAUTHORITY` or `WAYLAND_DISPLAY` + `DBUS_SESSION_BUS_ADDRESS`. The
portal answers on the first pattern, which ends the walk there, as it already
did on desktops that do export an xauth.
The loop also assigned all four variables unconditionally per pattern, so the
patterns that do not run on a given desktop blanked out what an earlier one had
answered with -- the portal's valid `DISPLAY=:1` included. That is why the
`--server` was then started with no `WAYLAND_DISPLAY` and no
`DBUS_SESSION_BUS_ADDRESS`. Candidates are now taken from one pattern as a whole
and ranked, so a later pattern replaces an earlier answer only by being better,
and a session that can only offer a compositor and a bus still keeps them.
A compositor that starts Xwayland on demand shows the same shape from the other
side: the portal came up before Xwayland did, so its environment carries a valid
`WAYLAND_DISPLAY` and `DBUS_SESSION_BUS_ADDRESS` but no `DISPLAY`, and no pattern
here may ever produce one. That pair alone is a session the child server can be
started against -- it is exactly what `get_display_xauth_wayland` returns on --
so it outranks a bare `DISPLAY` and ends the retrying, while the rest of the
round still looks for something that completes the session.
Not specific to the drm build: the function is not feature-gated, and the commit
the report points at does not touch it.

* fix(linux): a session logout should hand the peer to the login screen
Logging out closes every window in the session, the connection manager's
included, and its close handler kicks every peer with the reason a person
gets when they disconnect one by hand. That reason is the one thing the
client never retries on, so the remote session dies on a frozen frame
instead of reconnecting to the greeter that is already there.
The close carries nothing to tell the two apart: measured on KDE, the CM
receives no signal and logind still reports the session active at that
instant, and the server is killed within a few hundred ms either way, so
neither a state check nor a grace period can decide it. What is
distinguishable is the ACTION: disconnecting a peer is not the same event
as this window going away. So the window-close path now says so, and the
server ends the session without poisoning the retry; the Disconnect
button and the app's own close control keep kicking exactly as before.
Linux only, since that is where a logout closes the window.
Verified on plasma/sddm with a client attached: a logout now reconnects
to the greeter with no dialog, while closing the manager window still
shows Closed manually by the peer.
* fix(linux): close the tunnel too, and keep the web build compiling
Three seams the first pass missed. The web bridge is hand written, not
generated, so the new call needs its stub there or flutter build web
stops compiling - and that job is disabled in CI, so it would have gone
green. try_port_forward_loop is a second consumer of the same channel
and only knew Close, so a forwarded tunnel outlived the window it was
supposed to die with. And the variant had landed inside the DRM section,
whose comment says everything below it is drm-gated.

AppRun sets XDG_DATA_DIRS to
"$APPDIR/usr/local/share:$APPDIR/usr/share:$XDG_DATA_DIRS". When the host
leaves XDG_DATA_DIRS unset, the result contains no /usr/share, and setting
the variable at all suppresses the XDG default of /usr/local/share:/usr/share.
gdk-pixbuf 2.43+ (Arch, CachyOS, Gentoo, Fedora, openSUSE) no longer ships PNG,
JPEG or WebP as loader modules; libgdk_pixbuf links libglycin and decodes them
through it, and glycin discovers its loaders in
$XDG_DATA_DIRS/glycin-loaders/<ver>/conf.d/*.conf. With /usr/share missing,
glycin finds none and every PNG decode inside the AppImage fails with
"Unrecognized image file format".
RustDesk sends remote cursors to flutter_custom_cursor as PNG, and that plugin
returns nullptr from a std::string function when the decode fails, so the first
non-default cursor of a session aborts the process:
GdkPixbuf-CRITICAL **: gdk_pixbuf_copy: assertion 'GDK_IS_PIXBUF (pixbuf)' failed
terminate called after throwing an instance of 'std::logic_error'
what(): basic_string::_M_construct null not valid
Debian and Ubuntu compile PNG straight into libgdk_pixbuf and never reach
glycin, which is why this only affects non-Debian hosts.
Append the two XDG defaults so they are present when the host does not provide
them. They go last, so a session that sets XDG_DATA_DIRS properly keeps its own
precedence, and appending is a no-op where those paths are already listed.
Verified on CachyOS (gdk-pixbuf 2.44.7) against a stock 1.4.9 AppImage: with
only this variable changed, a full remote session runs without crashing and
renders remote cursors correctly.

* Prefer active X11 session display
* Update linux.rs
* fix(linux): keep the logind display only when it is a local one
`get_display_from_session` returns the value pam_systemd was handed at session
creation, and logind never updates it afterwards. That value is not always a
usable local display: it can be qualified with this host (`myhost:0`), name an
X forwarding endpoint (`localhost:10.0`), or be a bare `:`.
Taking it unconditionally is worse than taking nothing, because a non-empty
`self.display` suppresses every fallback below it, `get_display_by_user` and the
`:0` default alike. The stripping at the end of `get_display_x11` does not save
the last two cases either: it leaves `:` as is and turns `localhost:10.0` into a
local looking `:10.0`, either of which is then exported as DISPLAY and leaves the
session unreachable, where before this PR the host got a working `:0`.
Strip this host so `myhost:0` is still accepted as `:0`, leave `localhost` in
place, and require a display number after the colon. Anything else falls through
to the existing chain.

The "Be minimally invasive" rules already ask for purely additive diffs, but not
in the case where the addition would otherwise reshape an existing function so
the two can share code. Repeating a few lines is the better diff there.

* fix(windows): restore keyboard focus when the cursor re-enters the remote image
On Windows the raw key focus node is unfocused on window blur and nothing
requests it back, so returning to an already connected session left the
keyboard dead until the remote image was clicked.
Request focus from enterView(), gated on the window being active, the tab
being selected and no blocking overlay, so a background window cannot grab
system keys. enterOrLeave(true) is still driven by RawKeyFocusScope's
onFocusChange, so it is not called twice.
* fix(windows): refocus on window focus when the cursor already hovers the image
Alt+Tab or a taskbar click returns focus without a PointerEnter, so
enterView() cannot restore the keyboard. Reuse _cursorOverImage, gated
on the selected tab and no blocking overlay.
* refactor(windows): share one focus predicate for every requestFocus path
The relative-mouse-mode restore on window focus could hand remote input
to this page while a blocking dialog was up or the tab was not selected.
* fix(flutter): make Adjust Window reliable across desktop platforms
- Fix incorrect sizing on scaled displays by calculating the target from the
rendered canvas scale and platform-specific window coordinate units.
- Fix adjustments using the wrong monitor by querying the current remote
window's screen, with the main window as fallback.
- Fix stale geometry after fullscreen or maximized transitions by refreshing
metrics before calculating and applying the target frame.
- Fix fullscreen availability checks on Windows and macOS by predicting the
restored window borders and caching each macOS window's pre-fullscreen work area.
- Fix incorrect Linux work areas by handling GNOME Wayland fractional scaling
and caching compositor/X11 work-area measurements when visibleFrame is wrong.
- Prevent unsafe adjustments by rejecting invalid, oversized, or implausibly
small target frames.
- Avoid failures during window teardown by skipping adjustment when the view,
screen, or native window frame is unavailable.

* fix(flutter): harden Adjust Window handling
- Use the dynamic Linux resize edge when predicting restored window bounds.
- Treat GNOME fractional-scaling lookup failures as unknown without repeating
the lookup for the remote window.
- Stop adjustment safely when native window calls fail during window teardown.

The CursorData constructor copies hotxOrigin into hoty. Latent today:
both consumers call updateGetKey() before reading, and _checkUpdateScale
recomputes hoty from hotyOrigin - but any future read before that call
inherits the x value silently.
* fix: hide the printer settings tab when settings are disabled
The Security and Network tabs already honour `disable-settings`, but the
Printer tab was gated only on `hide-remote-printer-settings`, so custom
clients built with settings disabled still exposed it.

* feat: add hide-general-settings builtin option
Hides the General tab of the settings page. Unlike the other
hide-*-settings options this one is still useful when settings are
disabled, since `disable-settings` does not cover the General tab.
