I have Windows 7, 64 bit. I'm running the example.py file (code posted below) that comes with the pyHook package. Whenever my active window is Skype, either my computer crashes or I get 'TypeError: KeyboardSwitch() missing 8 required positional arguments: ..'. I assume that the code in the example is okay, and if I'm not using Skype it runs fine. Any thoughts?
from __future__ import print_function
import pyHook
def OnMouseEvent(event):
print('MessageName:',event.MessageName)
print('Message:',event.Message)
print('Time:',event.Time)
print('Window:',event.Window)
print('WindowName:',event.WindowName)
print('Position:',event.Position)
print('Wheel:',event.Wheel)
print('Injected:',event.Injected)
print('---')
# return True to pass the event to other handlers
# return False to stop the event from propagating
return True
def OnKeyboardEvent(event):
print('MessageName:',event.MessageName)
print('Message:',event.Message)
print('Time:',event.Time)
print('Window:',event.Window)
print('WindowName:',event.WindowName)
print('Ascii:', event.Ascii, chr(event.Ascii))
print('Key:', event.Key)
print('KeyID:', event.KeyID)
print('ScanCode:', event.ScanCode)
print('Extended:', event.Extended)
print('Injected:', event.Injected)
print('Alt', event.Alt)
print('Transition', event.Transition)
print('---')
# return True to pass the event to other handlers
# return False to stop the event from propagating
return True
# create the hook mananger
hm = pyHook.HookManager()
# register two callbacks
hm.MouseAllButtonsDown = OnMouseEvent
hm.KeyDown = OnKeyboardEvent
# hook into the mouse and keyboard events
hm.HookMouse()
hm.HookKeyboard()
if __name__ == '__main__':
import pythoncom
pythoncom.PumpMessages()
I had this and traced it to a UnicodeDecodeError when pyHook tries to interpret the window name as ascii. It fails on Skype which has unicode characters in its window name. I've posted how I fixed it here. But I had to rebuild pyHook.
PS: kind of a duplicate answer but wanted to connect this question to what I found.

I tried to run parallel, but it didn't work as I expected
The progress bar doesn't work the way I thought it would.
I think that both operations should be executed at the same time.

I am not sure but I think you should set up a executor with parallelism available. You could use multiprocess_executor.
"Executors are responsible for executing steps within a pipeline run.
Once a run has launched and the process for the run, or run worker,
has been allocated and started, the executor assumes responsibility
for execution."
modes provide the possible set of executors one can use. Use the executor_defs property on ModeDefinition.
MODE_DEV = ModeDefinition(name="dev", executor_defs=[multiprocess_executor])
#pipeline(mode_defs=[MODE_DEV], preset_defs=[Preset_test])
the execution config section of the run config determines the actual executor.
in the yml file or run_config, set:
execution:
multiprocess:
config:
max_concurrent: 4

I know because of the logs that I should not do any HTTP request inside "vehicle.on_attribute" decorator method and I should search for information on how to solve this problem but I didn't found any info about the error.
Hope you could help me.
Thank you very much,

The emit() function by default returns an event back to the active client. If you call this function outside of a request context there is no concept of active client, so you get this error.
You have a couple of options:
indicate the recipient of the event and the namespace that you are using, so that there is no need to look them up in the context. You can do this by adding room and namespace arguments. Use '/' for the namespace if you are using the default namespace.
emit to all clients by adding broadcast=True as an argument, plus the namespace as indicated in #1.
I'm trying to get the external IP that Tor uses, as mentioned here. When using something like myip.dnsomatic.com, this is very slow. I tried what was suggested in the aforementioned link (python + stem to control tor through the control port), but all you get is circuit's IPs with no assurance of which one is the one on the exitnode, and, sometimes the real IP is not even among the results.
Any help would be appreciated.
Also, from here, at the bottom, Amine suggests a way to renew the identity in Tor. There is an instruction, controller.get_newnym_wait(), which he uses to wait until the new connection is ready (controller is from Control in steam.control), isn't there any thing like that in Steam (sorry, I checked and double/triple checked and couldn't find nothing) that tells you that Tor is changing its identity?
You can get the exit node ip without calling a geoip site.
This is however on a different stackexchange site here - https://tor.stackexchange.com/questions/3253/how-do-i-trap-circuit-id-none-errors-in-the-stem-script-exit-used-py
As posted by #mirimir his code below essentially attaches a stream event listener function, which is then used to get the circuit id, circuit fingerprint, then finally the exit ip address -
#!/usr/bin/python
import functools
import time
from stem import StreamStatus
from stem.control import EventType, Controller
def main():
print "Tracking requests for tor exits. Press 'enter' to end."
print
with Controller.from_port() as controller:
controller.authenticate()
stream_listener = functools.partial(stream_event, controller)
controller.add_event_listener(stream_listener, EventType.STREAM)
raw_input() # wait for user to press enter
def stream_event(controller, event):
if event.status == StreamStatus.SUCCEEDED and event.circ_id:
circ = controller.get_circuit(event.circ_id)
exit_fingerprint = circ.path[-1][0]
exit_relay = controller.get_network_status(exit_fingerprint)
t = time.localtime()
print "datetime|%d-%02d-%02d %02d:%02d:%02d % (t.tm_year, t.tm_mon, t.tm_mday, t.tm_hour, t.tm_min, t.tm_sec)
print "website|%s" % (event.target)
print "exitip|%s" % (exit_relay.address)
print "exitport|%i" % (exit_relay.or_port)
print "fingerprint|%s" % exit_relay.fingerprint
print "nickname|%s" % exit_relay.nickname
print "locale|%s" % controller.get_info("ip-to-country/%s" % exit_relay.address, 'unknown')
print
You can use this code for check current IP (change SOCKS_PORT value to yours):
import re
import stem.process
import requesocks
SOCKS_PORT = 9053
tor_process = stem.process.launch_tor()
proxy_address = 'socks5://127.0.0.1:{}'.format(SOCKS_PORT)
proxies = {
'http': proxy_address,
'https': proxy_address
}
response = requesocks.get("http://httpbin.org/ip", proxies=proxies)
print re.findall(r'[\d.-]+', response.text)[0]
tor_process.kill()
If you want to use socks you should do:
pip install requests[socks]
Then you can do:
import requests
import json
import stem.process
import stem
SOCKS_PORT = "9999"
tor = stem.process.launch_tor_with_config(
config={
'SocksPort': SOCKS_PORT,
},
tor_cmd= 'absolute_path/to/tor.exe',
)
r = requests.Session()
proxies = {
'http': 'socks5://localhost:' + SOCKS_PORT,
'https': 'socks5://localhost:' + SOCKS_PORT
}
response = r.get("http://httpbin.org/ip", proxies=proxies)
self.current_ip = response.json()['origin']
I'm creating a module for OpenERP in which I have to launch an ongoing process.
OpenERP runs in a continuous loop. My process has to be launched when I click on a button, and it has to keep running without holding up OpenERP's execution.
To simplify it, I have this code:
#!/usr/bin/python
import multiprocessing
import time
def f(name):
while True:
try:
print 'hello', name
time.sleep(1)
except KeyboardInterrupt:
return
if __name__ == "__main__":
count = 0
while True:
count += 1
print "Pass %d" % count
pool = multiprocessing.Pool(1)
result = pool.apply_async(f, args=['bob'])
try:
result.get()
except KeyboardInterrupt:
#pass
print 'Interrupted'
time.sleep(1)
When executed, Pass 1 is printed once and then an endless series of hello bob is printed until CTRL+C is pressed. Then Pass 2 is obtained and so on, as shown below:
Pass 1
hello bob
hello bob
hello bob
^CInterrupted
Pass 2
hello bob
hello bob
hello bob
hello bob
I would like the passes to keep increasing in parallel with the hello bob's.
How do I do that?
Here what you can do id you can create then Multi Threaded Implementation of Python under the server memory, which will run independently then server execution thread.
Trick behind this will be used is we will fork one thread from server on your required click and we will assign all server variable separate copy to the new Thread so that thread will execute independently and at then end of process you have to commit the transaction as this process will be not main server process. Here the small example of it how you can do it .
import pprint
import pooler
from threading import Thread
import datetime
import logging
pp = pprint.PrettyPrinter(indent=4)
class myThread(Thread):
"""
"""
def __init__(self, obj, cr, uid, context=None):
Thread.__init__(self)
self.external_id_field = 'id'
self.obj = obj
self.cr = cr
self.uid = uid
self.context = context or {}
self.logger = logging.getLogger(module_name)
self.initialize()
"""
Abstract Method to be implemented in the real instance
"""
def initialize(self):
"""
init before import
usually for the login
"""
pass
def init_run(self):
"""
call after intialize run in the thread, not in the main process
TO use for long initialization operation
"""
pass
def run(self):
"""
this is the Entry point to launch the process(Thread)
"""
try:
self.init_run()
#Your Code Goes Here
#TODO Add Business Logic
self.cr.commit()
except Exception, err:
sh = StringIO.StringIO()
traceback.print_exc(file=sh)
error = sh.getvalue()
print error
self.cr.close()
LIke this you can add some code in some module like (import_base module in 6.1 or trunk)
Now what Next you can do is you can make extended implementation of this and then make instace of the service or you can directly start forking the treads like following code:
service = myServcie(self, cr, uid, context)
service.start()
now this we start background services which run faster and give you freedom to use the UI.
Hope this will help you
Thank You
I have a setup such that an nginx server passes control off to uWsgi, which launches a pylons app using the following in my xml configuration file:
<ini-paste>...</ini-paste>
Everything is working nicely, and I was able to set it to debug mode using the following in the associated ini file, like:
debug = true
Except debug mode only prints out errors, and doesn't reload the code everytime a file has been touched. If I was running directly through paste, I could use the --reload option, but going through uWsgi complicates things.
Does anybody know of a way to tell uWsgi to tell paste to set the --reload option, or to do this directly in the paste .ini file?
I used something like the following code to solve this, the monitorFiles(...) method is called on application initialization, and it monitors the files, sending the TERM signal when it sees a change.
I'd still much prefer a solution using paster's --reload argument, as I imagine this solution has bugs:
import os
import time
import signal
from deepthought.system import deployment
from multiprocessing.process import Process
def monitorFiles():
if deployment.getDeployment().dev and not FileMonitor.isRunning:
monitor = FileMonitor(os.getpid())
try: monitor.start()
except: print "Something went wrong..."
class FileMonitor(Process):
isRunning = False
def __init__(self, masterPid):
self.updates = {}
self.rootDir = deployment.rootDir() + "/src/python"
self.skip = len(self.rootDir)
self.masterPid = masterPid
FileMonitor.isRunning = True
Process.__init__(self)
def run(self):
while True:
self._loop()
time.sleep(5)
def _loop(self):
for root, _, files in os.walk(self.rootDir):
for file in files:
if file.endswith(".py"):
self._monitorFile(root, file)
def _monitorFile(self, root, file):
mtime = os.path.getmtime("%s/%s" % (root, file))
moduleName = "%s/%s" % (root[self.skip+1:], file[:-3])
moduleName = moduleName.replace("/",".")
if not moduleName in self.updates:
self.updates[moduleName] = mtime
elif self.updates[moduleName] < mtime:
print "Change detected in %s" % moduleName
self._restartWorker()
self.updates[moduleName] = mtime
def _restartWorker(self):
os.kill(self.masterPid, signal.SIGTERM)
