      org.freedesktop.Flatpak.SessionHelper:
      @short_description: Flatpak session service

      The Flatpak session service is used by the
      <command>flatpak run</command> command
      to bridge various resources from the host system into Flatpak
      sandboxes. It is not intended to be contacted by third-party
      applications or libraries.

      This interface is provided on the D-Bus session bus by the
      well-known D-Bus name org.freedesktop.Flatpak,
      at the object path /org/freedesktop/Flatpak/SessionHelper.

      Note that the service owning the org.freedesktop.Flatpak
      well-known name also exports the
      org.freedesktop.Flatpak.Development interface. As a result,
      letting a sandboxed application contact that well-known name
      is a sandbox escape, which must only be allowed for trusted
      applications where there is not intended to be any security
      boundary between sandbox and host system.

      This documentation describes version 1 of this interface.

      org.freedesktop.Flatpak.Development:
      @short_description: Flatpak development interface

      The Development interface lets any client, possibly in a sandbox if
      it has access to the session helper, spawn a process on the host,
      outside any sandbox.

      Clearly this is not something you typically want a sandboxed app to
      do: it is a sandbox escape allowing arbitrary code execution,
      and must not be allowed for applications where sandboxing is
      intended to be a security boundary.

      However, it is very useful when using Flatpak for distribution and
      choice of runtime library stack, without intending to create a
      security boundary. For instance, if an IDE like GNOME Builder is
      distributed as a trusted Flatpak app and will be used to build other
      Flatpak apps, it needs to use this facility to launch a Flatpak
      build operation inside the sandbox, because otherwise recursive
      calls to flatpak will not work.

      This interface is provided on the D-Bus session bus by the
      well-known D-Bus name org.freedesktop.Flatpak,
      at the object path /org/freedesktop/Flatpak/Development.

      This documentation describes version 1 of this interface.

        HostCommand:
        @cwd_path: the working directory for the new process
        @argv: the argv for the new process, starting with the executable to launch
        @fds: an array of file descriptors to pass to the new process
        @envs: an array of variable/value pairs for the environment of the new process
        @flags: flags
        @pid: the PID of the new process

        This method lets trusted applications (insider or outside a
        sandbox) run arbitrary commands in the user's session, outside
        any sandbox.

        The following flags values are supported:

        <variablelist>
          <varlistentry>
            <term>1 (FLATPAK_HOST_COMMAND_FLAGS_CLEAR_ENV)</term>
            <listitem><para>
              Clear the environment.
            </para></listitem>
          </varlistentry>
          <varlistentry>
            <term>2 (FLATPAK_HOST_COMMAND_FLAGS_WATCH_BUS)</term>
            <listitem><para>

            </para></listitem>
          </varlistentry>
        </variablelist>

        Unknown (unsupported) flags are an error and will cause HostCommand()
        to fail.

        Note that unlike org.freedesktop.portal.Flatpak.Spawn(), there
        is no options parameter here.

        This signal is not emitted for processes that were not launched
        directly by HostCommand(), for example if a process launched by
        HostCommand() runs foreground or background child processes.

      org.freedesktop.Flatpak.SystemHelper:
      @short_description: Flatpak system service

      The Flatpak system service is used by the libflatpak library
      to manipulate Flatpak applications and runtimes that are installed
      system-wide, for example when implementing
      <command>flatpak install</command>.
      It is not intended to be contacted by third-party applications
      or libraries. See the Flatpak source code for more
      details of this interface's methods.

      This interface is provided on the D-Bus system bus by the
      well-known D-Bus name org.freedesktop.Flatpak.SystemHelper,
      at the object path /org/freedesktop/Flatpak/SystemHelper.

      The system helper runs as a privileged user at the system level,
      and receives method calls from less-privileged users.
      Authorization for method calls on this interface is mediated by
      polkit (formerly PolicyKit) using the policy configuration
      org.freedesktop.Flatpak.policy, and can be configured by
      system administrators in the same way as for any other system service
      that uses polkit.
