Method Details [hide private]

__init__(self, cmd, std_in=None, timeout=30, pipesize=0, blocksize=1024, capturestderr=False)
(Constructor)

source code  

cmd       = command to be executed.
std_in    = input for the command.
timeout   = timeout between blocks of the command output (in seconds).
pipesize  = the size (in blocks) of the queue used to buffer
            the blocks read.
blocksize = the maximum block size for a raw read.
capturestderr if True tells to merge std_out and std_err of the command.

submit(self)

source code 

Legacy method. Deprecated.

isRunning(self)

source code 

Shows is command running or not. If there is no way to establish this (win32 without extensions) always returns True.

readOutput(self, pipe_ind, maxblocks=0, timeout=None)

source code 

Read no more than maxblocks from out pipe i. i = 0 std_out (or std_out + std_err) i = 1 std_err. If maxblocks = 0 (default) read till the end of data or timeout between blocks arrival

finalize(self)

source code 

Tries to kill command process, close pipes and stop threads. Can block on win32 without win extensions.

getOutput(maxblocks=...)

source code  
--> [std_out and std_err lines],
    if capturestderr = True
--> ([std_out lines], [std_err lines]),
    if capturestderr = False
