Hi Everyone, I am fairly new to Node.js and I have a hard time trying to figure this one out. Here's I am trying to do:
I have a node instance acting as a master program who will spawn other long running applications (possible up to 100 programs) (that is not a node.js instance) as worker applications. I would like my node instance to be able to communicate with them via a REPL style, that is 1) node would issue "work commands" to the worker applications, 2) and the worker applications would be reply with "acknowledgements", "work done" or "error" back to the node, so 3) node.js could effective schedule jobs and optimize the worker applications. The problem here is that the streams between node and the child_process are buffered by default to a length of 8192 bytes, which means that I have to pad my message until it is of this length which is inelegant. I want a much smaller buffer for message, which presumably would be give less communications overhead, and I dont want to be counting characters to make just they return in the same buffer at every message response. Making stream emit a "data" on detection of a "\0" character would be idea. I have tried, various custom stdio options for child_process<http://nodejs.org/api/child_process.html#child_process_child_process_spawn_command_args_options>, to try to modify the buffer length but it was to no avail. Help or pointers would be very much appreciated!
