[SOLVED] Sending large file in websocket before timeout

Sending large file in websocket before timeout

I'm using Faye and EventMachine to open a socket to another server. The server times out if it doesn't detect activity. How do I send the file (binary encoded) so the server doesn't time out?

Here's what I have:

media_path = "/path/to/media/file"

EM.run {
  ws = Faye::WebSocket::Client.new(uri)

  ws.on :open do |event|
    puts "Opening socket"
    ws.send(File.read(media_path))
  end

  ws.on :message do |event|
    puts "Recieving message"
  end

  ws.on :close do |event|
    ws = nil
    EM.stop
  end
}

Solution

You need to send your file in batches. Something like that:

ws.on :open do |event|
  puts "Opening socket"
  File.open('filename','r') do |f|
    ws.send(f.gets)
  end
end

You solve another problem this way: you wouldn't place your whole file in RAM + you'll send it faster. You can read about nodejs streams, there is a similar principle of operation.
