urllib.urlopen blocking?

[Dominik Gabi]

Hi,

I'm new to python and have been playing around with it for a few days
now. So please forgive me if this is a stupid question

I've tried writing a little application with pygtk and urllib. When a
button is clicked I create a new thread that opens an URL with urllib.
The new thread is running but as soon as I call
urllib.urlopen("https://someurl", postdata) it blocks. It blocks until
I do something in the interface (e.g. click another button). I've
obviously missed something here. The interface should not interfere
with anything that runs in an other thread!?

Here are a few extracts from my code:

def send_message(self, widget, data=None):
# This is called when the button is clicked ...
threading.Thread(target=message.send).start() ...

def send(self):
# This is executed in its own thread
...
postdata = urllib.urlencode(data) # This line is the last one
executed
resp = urllib.urlopen('https://theurl', postdata)

Regards, Dominik.

For the record, have you tried calling gobject.threads_init() at the
beginning of your application (just after importing all modules)?

I haven't... now it works, thanks Any tips on how to avoid mistakes
like that in the future? I'm somewhat confused as to how I was
supposed to get this out of the documentation...

I'm afraid I don't know the answer. I'm not a pygtk expert at all, I
just remember that I had to do that in one of my applications long ago,
otherwise pygtk doesn't support Python threads properly.
