rustdesk 20b3540151 server: end a connection a newer one from the same session has replaced
When a controller's link dies without a close reaching the peer - the only case
that matters, since anything graceful already closes cleanly - the connection it
abandoned keeps running here until the inactivity timeout. If the controller
reconnects in the meantime, and it does, two connections for one session overlap,
and everything the stale one costs is charged to the session that replaced it.

The cost is not only cosmetic. A stale remote control or camera view stays a
video subscriber, and the capture loop waits for every subscriber to fetch the
current frame before capturing the next, for up to three seconds; a connection
whose own send is blocked never fetches, so frames for the live session arrive at
that rate. It stays a viewer the rate control averages in, holding the shared
target down. A stale transfer or tunnel holds its own resources. And the
connection manager lists it: its own same-peer dedup only drops entries already
marked disconnected, which this one is not.

So end it when the replacement authorizes. Same kind only: one session
legitimately holds remote control and a file transfer or port forward at once,
and those must not end each other, while two of the same kind under one session
id is what only a link failing without a close can produce. Nothing is sent to
the peer - the link it would go over is the one that just failed, and the peer
that owned this connection has already moved on - and the screen is not locked,
because the session is continuing rather than ending.

Dependencies

Desktop versions use Flutter or Sciter (deprecated) for GUI. This tutorial is for Sciter only, since it is easier and more friendly to start. Check out our CI for building the Flutter version.

Please download Sciter dynamic library yourself.

Raw Steps to build

  • Prepare your Rust development env and C++ build env

  • Install vcpkg, and set VCPKG_ROOT env variable correctly

    • Windows: vcpkg install libvpx:x64-windows-static libyuv:x64-windows-static opus:x64-windows-static aom:x64-windows-static
    • Linux/macOS: vcpkg install libvpx libyuv opus aom
  • run cargo run

Fedora 28 (CentOS 8)

Install vcpkg

git clone https://github.com/microsoft/vcpkg
cd vcpkg
git checkout 2023.04.15
cd ..
vcpkg/bootstrap-vcpkg.sh
export VCPKG_ROOT=$HOME/vcpkg
vcpkg/vcpkg install libvpx libyuv opus aom

Fix libvpx (For Fedora)

cd vcpkg/buildtrees/libvpx/src
cd *
./configure
sed -i 's/CFLAGS+=-I/CFLAGS+=-fPIC -I/g' Makefile
sed -i 's/CXXFLAGS+=-I/CXXFLAGS+=-fPIC -I/g' Makefile

cp libvpx.a $HOME/vcpkg/installed/x64-linux/lib/
cd

Build

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
source $HOME/.cargo/env
git clone --recurse-submodules https://github.com/rustdesk/rustdesk
cd rustdesk
mkdir -p target/debug
wget https://raw.githubusercontent.com/c-smile/sciter-sdk/master/bin.lnx/x64/libsciter-gtk.so
mv libsciter-gtk.so target/debug

How to build with Docker

Begin by cloning the repository and building the Docker container:

git clone https://github.com/rustdesk/rustdesk
cd rustdesk
git submodule update --init --recursive
docker build -t "rustdesk-builder" .

Then, each time you need to build the application, run the following command:

docker run --rm -it -v $PWD:/home/user/rustdesk -v rustdesk-git-cache:/home/user/.cargo/git -v rustdesk-registry-cache:/home/user/.cargo/registry -e PUID="$(id -u)" -e PGID="$(id -g)" rustdesk-builder

Note that the first build may take longer before dependencies are cached, subsequent builds will be faster. Additionally, if you need to specify different arguments to the build command, you may do so at the end of the command in the <OPTIONAL-ARGS> position. For instance, if you wanted to build an optimized release version, you would run the command above followed by --release. The resulting executable will be available in the target folder on your system, and can be run with:

target/debug/rustdesk

Or, if you're running a release executable:

target/release/rustdesk

Please ensure that you run these commands from the root of the RustDesk repository, or the application may not find the required resources. Also note that other cargo subcommands such as install or run are not currently supported via this method as they would install or run the program inside the container instead of the host.
