Remote Procedure Call

Connector can do RPC in a easy way. It can call functions, call system commands and run scripts on remote computer. In following description, client means client object on client side, means client peer on server side.

• client.eval(statement, block = True): Let remote computer call python eval and get return value.

  • statement: The string of Python code.

  • block: If block is True, it will block process until remote eval returns. Otherwise it will immediately return a Future object which you can call result() on it to get real return value.

• client.exec(code, block = True): Let remote computer call python exec and get return value. Usage just like client.eval.

• client.execfile(local_script_path, block=True): Let remote computer run a local python script.

  • local_script_path: Script file path on local computer.

  • block: If block is True, it will block process until remote computer run script finished. Otherwise, it will immediately return a Future object which you can call result() on to wait it finished.

• client.exec_remote_file(remote_script_path, block=True): Let remote computer run a remote python script. The usage is just like client.execfile.

• client.system(cmd, quiet=False, remote_quiet=False, once_all=False, block=True): Let remote computer run system command.

  • cmd: System command string need to be call.

  • quiet: If quiet is True, local side won’t print anything of standard output and standard error.

  • remote_quiet: If it’s True, remote side won’t print anything of standard output and standard error.

  • once_all: Local and remote side won’t print anything during system call processing and will print message after system finished.

  • block: If block is True, it will block process until system call finished and return system call’s return value. Otherwise, it will immediately return a Future object which you can call result() on it to get system call’s return value.

• client.call(function, args=(), kwargs={}, block=True): Let remote computer call a local function.

  • function: A local callable python object, for example print is OK.

  • args: Function’s positional arguments need to be passed.

  • kwargs: Function’s key words arguments need to be passed.

  • block: If block is True, it will block process until remote computer call this function finished and return this function calling return value. Otherwise, it will immediately return a Future object which you can call result() on it to get function calling return value.

• client.call_remote(function_name, args=(), kwargs={}, block=True): Let remote computer call a remote function.

  • function_name: A remote function name string, for example "print" is OK.

  • args: Function’s positional arguments need to be passed.

  • kwargs: Function’s key words arguments need to be passed.

  • block: If block is True, it will block process until remote computer call this function finished and return this function calling return value. Otherwise, it will immediately return a Future object which you can call result() on it to get function calling return value.
