xvfb-run accepts some parameters and calls CutyCapt with parameters for it
The command is this:
xvfb-run --auto-servernum --server-num=55 --server-args "-screen 0,
> 1024x768x24" {0} --url="{1}" --private-browsing=on --out={2}
So server1, opens a process with CutyCapt which points to server1
address/url, does its thing and saves the result in out
Server2 in the other hand has a different address/url, different
server-num, and different out
As a workarround i've added close_fds=True, preexec_fn=os.setsid, and
after communicate(), i am doing os.killpg(server1.pid, signal.SIGUSR1)
Although i am not sure if this will work 100% because i have to wait X days
until something crashes
Any ideas are welcomed
P.S. After adding os.killpg, lsof and ps aux dont show more than 4 or 5
xvfb and cutycapt processes while running
Thanks and Regards

Re: problem in event handling on change of variable value.
hello sirjee,
i have read You solution for handling of events from CANoe in python.
I've implemented and its work correctly when I waiting in a msgbox (0,
"Finished the Test", "Info", 16).
I will implement it in a loop with a sleep time. The standard python
function of the sleep blocks the actual task and the event handling dosn't
work.
Now I search for a solution to start the event class in a extra task with
treahding.Thread.
I've write a simple claas for testing of this:
class Tester (threading.Thread):
def __init__ (self, variable):
threading.Thread.__init__ (self)
self.__debug = True
self.__env_event = None
self.__appl = win32com.client.Dispatch
('CANoe.Application')
self.__env = self.__appl.Environment
self.__var_name = variable
self.__var = self.__env.GetVariable (variable)
def run (self):
if self.__var != None:
self.__env_event = win32com.client.WithEvents
(self.__var, Tester)
print 'run'
i = 0
while True:
pass
time.sleep (10)
print i
i = i + 1
def OnChange (self, value):
if self._debug: print ('VariableEvents:OnChange now called
with %s' %value)
a = Tester ('dummy')
a.start ()
The run() dosn't work. I can't register the COM event. Have You a solution
for this?
The claas tester works without self.__env_event =
win32com.client.WithEvents (self.__var, Tester).
Regards,
Bernd

networking question: 2-way messaging w/o wireless modem config?
I have a Raspberry Pi board with a wireless usb modem on it. I wish to be able to message 2-way with the board from across the internet, without having to open ports on the wireless modem. Is there a way to do this? I have been looking at udp, but imagine that a udp packet is allowed in, but not out? The amount of data transmission I want is very small, maybe lt 30 bytes. So a client http request could include this data? I have been looking at messaging systems like MQTT as well, but don't know if they require opening a port in the typical modem-router. Any ideas appreciated! -- https://mail.python.org/mailman/listinfo/python-list

The answer depends on how you setup your wireless modem | router. There are many ways to set this up depending on your project goals. If you're trying to setup a sniffer (well, just don't do that, its not nice). If you were trying to setup a micro server on my network (for instance), well, you couln't, because I don't permit the outgoing connection without authorization and port (actually, same is true for incoming connections. I would have to setup auth and port for you to connect your Pi as a micro server on my wireless network. Most public access points are blocked (peer to peer) too (if they're smart). For legitimate non trivial setups (not experiments) you want to control the connection with auth and ports. A word of caution about udp. If the data you are sending is contained in one datagram (one packet), then no problem; however, if you are sending multiple packets over the WAN it can be a big problem because the upd in|out does not guarantee correct packet ordering. Is there a python question in here somewhere? marcus -- https://mail.python.org/mailman/listinfo/python-list
Soap list and soap users on this list

I've used SOAP, but not with Python. (I've also used soap, but never with any form of python. Snakes can stay dirty for all I care.) Wouldn't really call myself a "soap user", tbh. Is your question regarding anything at all Python, or are you just looking for helpful nerds? :) ChrisA -- https://mail.python.org/mailman/listinfo/python-list
RE: Soap list and soap users on this list
> Is your question > regarding anything at all Python, or are you just looking for helpful > nerds? :) Hi Chris, Thanks for responding. I've been looking at Spyne to produce a service that can accept a request formatted as follows: http://..."; xmlns:xsi=http:/..." xmlns:xsd="http://...";> Where I am interested in the ID attribute of the attr tag as well as _all_ the varying xml within the data tags. The docs are good, but a bit thin on more intricate examples. Maybe your previous soap experience might lead you to a tip that would eternally in debt me to you:) I have only ever done the most simplest work with soap and or ajax and hence got away with not knowing much... Thanks again for your help! jlc -- https://mail.python.org/mailman/listinfo/python-list

Usually, with consumer modems, you can do http client activity. (just connect another PC to the local network.) So I guess I could iniate a http request from the Pi. I just wondered if there were other protocols that would allow me to just communicate with the Pi. As far as sniffers etc., I adhere to a complete personal honesty - that's my policy, as anything else just won't do. I hope to program the item in Python, though I'm wondering if C is better for network programming. Thanks for help. jb -- https://mail.python.org/mailman/listinfo/python-list

You can do basic TCP/IP sockets pretty much the same way in every language, but with high level languages like Python, you get extra facilities that C won't give - most notably, the urllib.request module [1]. Same goes for quite a few other high level protocols. Take the easy way out! ChrisA [1] https://docs.python.org/3/library/urllib.request.html -- https://mail.python.org/mailman/listinfo/python-list
