Daemon imlementation

Modules

workspace 🔒

Structs

Client 🔒

Representation of a client

Clients 🔒

Collection of Clients maintaining insertion order and a PID-indexed lookup table.

Daemon 🔒

The daemon is responsible to launch a client for each host, positioning the client windows, forwarding input records to all clients and handling control mode.

HWNDWrapper 🔒

Hacky wrapper around a window handle.

Enums

ControlModeState 🔒

Enum of all possible control mode states.

PipeServerState 🔒

Runtime state of a client’s assigned pipe server task.

Constants

SENDER_CAPACITY 🔒

The capacity of the broadcast channel used to send the input records read from the console input buffer to the named pipe servers connected to each client in parallel.

Functions

arrange_client_window 🔒

Re-sizes and re-positions the given client window based on the total number of clients, the size of the daemon console window and its index relative to the other client windows.

defer_windows 🔒

Move all given windows to the foreground.

determine_client_spatial_attributes 🔒

Calculates the position and dimensions for a client window given its index, the total number of clients and the aspect_ratio_adjustment daemon configuration.

ensure_client_z_order_in_sync_with_daemon 🔒

Spawns a background thread that ensures the z-order of all client windows is in sync with the daemon window. I.e. if the daemon window is focussed, all clients should be moved to the foreground.

get_console_rect 🔒

Transform the position and dimensions of a console window based on the workspace area.

get_console_window_wrapper 🔒

Returns a window handle to the current console window.

get_foreground_window_wrapper 🔒

Returns a window handle to the foreground window.

launch_client_console 🔒

Launchs a client console process with its own window with the given CLI arguments/options: host, username, port, debug.

launch_clients 🔒

Launches a client console for each given host and waits for the client windows to exist before returning their handles.

main

The entrypoint for the daemon subcommand.

named_pipe_server_routine 🔒

Wait for the named pipe server to connect, correlate the client by its process id, then forward serialized input records read from the broadcast channel to the named pipe server.

read_client_pid 🔒

Read the connecting client’s 4 byte little-endian process id from the pipe.

resolve_cluster_tags

Resolve cluster tags into hostnames

toggle_processed_input_mode 🔒

The processed console input mode controls whether special key combinations such as Ctrl + c or Ctrl + BREAK receive special handling or are treated as simple key presses.
