Detailed Description

This class provides a wrapper around a subprocess that
implements a simple request/response usage model. The primary benefit
is that reading responses takes a deadline, so that we don't ever block
indefinitely. The class also handles transparently restarting processes
as necessary to keep issuing commands.

__init__()

def webkitpy.port.server_process.ServerProcess.__init__	(		self,
			port_obj,
			name,
			cmd,
			env = None,
			universal_newlines = False,
			treat_no_data_as_crash = False,
			worker_number = None
	)

Member Function Documentation

has_crashed()

def webkitpy.port.server_process.ServerProcess.has_crashed

(

self

)

kill()

def webkitpy.port.server_process.ServerProcess.kill

(

self

pid()

def webkitpy.port.server_process.ServerProcess.pid

(

self

poll()

def webkitpy.port.server_process.ServerProcess.poll

(

			deadline
	)

read_stderr_line()

def webkitpy.port.server_process.ServerProcess.read_stderr_line	(		self,
			deadline
	)

read_stdout()

def webkitpy.port.server_process.ServerProcess.read_stdout	(		self,
			deadline,
			size
	)

read_stdout_line()

def webkitpy.port.server_process.ServerProcess.read_stdout_line	(		self,

			timeout_secs = 3.0
	)

write()

def webkitpy.port.server_process.ServerProcess.write	(		self,
			bytes,
			ignore_crash = False
	)

Write a request to the subprocess. The subprocess is (re-)start()'ed
if is not already running.
