Hi,
issue in implementing multiprocessing with pxssh, its working fine with normal
operations but with pxssh its throwing error as below:
=========
multiprocessing.pool.RemoteTraceback:
"""
Traceback (most recent call last):
File "/usr/python/3.4.3/Lib/multiprocessing/pool.py", line 119, in worker
result = (True, func(*args, **kwds))
File "/usr/python/3.4.3/Lib/multiprocessing/pool.py", line 44, in mapstar
return list(map(*args))
File "./rmcomments.py", line 12, in xcute
s = pxssh.pxssh()
File
"/usr/python/3.4.3/custommodules/lib/python3.4/site-packages/pexpect/pxssh.py",
line 91, in __init__
spawn.__init__(self, None, timeout=timeout, maxread=maxread,
searchwindowsize=searchwindowsize, logfile=logfile, cwd=cwd, env=env)
File
"/usr/python/3.4.3/custommodules/lib/python3.4/site-packages/pexpect/__init__.py",
line 493, in __init__
fd = sys.__stdin__.fileno()
ValueError: I/O operation on closed file
"""
The above exception was the direct cause of the following exception:
Traceback (most recent call last):
File "./rmcomments.py", line 23, in <module>
output = p.map(xcute, [(srvrs) for srvrs in serverslist])
File "/usr/python/3.4.3/Lib/multiprocessing/pool.py", line 260, in map
return self._map_async(func, iterable, mapstar, chunksize).get()
File "/usr/python/3.4.3/Lib/multiprocessing/pool.py", line 599, in get
raise self._value
ValueError: I/O operation on closed file
======
Below is the code:
------------------------
serverslist = ['server1','server2']
username = 'user1'
password = 'password1'
def xcute(srvrs):
s = pxssh.pxssh()
s.login (srvrs, username, password)
---do stuff---
s.sendline('logout')
np = len(serverslist)
p = multiprocessing.Pool(np)
output = p.map(xcute, [(srvrs) for srvrs in serverslist])
can any one help me out!!!!!
Thanks
