Port Discovery Protocol

Port discovery is the mechanism where the Runtime transmits its WS Port information to interested parties. On each successful launch, once the socket server has obtained a port the Runtime will publish port Information via two mechanisms:

WMCopyData:

If a window with a class name OPENFIN_ADAPTER_WINDOW is found it will receive a WMCopyData message with the following payload:

{
    version: string,
    sslPort: number (defaults to -1),
    port: number,
    requestedVersion: string (example: "stable", "beta", "alpha"),
    securityRealm: string,
    runtimeInformationChannel: string
}

Named Pipes

If the runtime-information-channel-v6 argument was passed during launch then its value will be used as the pipe name for a chromeIpc send message containing the following payload:

{
    action: "runtime-information",
    payload: {
        version: string,
        sslPort: number (defaults to -1),
        port: number,
        requestedVersion: string (example: "stable", "beta", "alpha"),
        securityRealm: string,
        runtimeInformationChannel: string
    }
}
