komodo thread problem
Komodo problem with threading: Hello, I can't run this program: def printtime(Max): i = 0 while True: time.sleep(1) print time.ctime(time.time()) i+=1 if i==Max : break pass if __name__ == "__main__": thread.start_new_thread(printtime,(2,)) But it runs inside IDLE. pujo -- http://mail.python.org/mailman/listinfo/python-list
freebsd thread problem
Hi there, I have installed python(2.4.3) & trac(0.9.4) on freebsd(4.8) from the ports collection and I seem to have an underlying problem with the thread module. Pysqlite is calling 'import thread' which is failing with "no such module" and causing it not to load. I thought that 'thread' was one of the core sys.modules and when I install python via ports I can see in the makefile that threading is turned on. Salling 'import thread' from the python prompt yields the same result. I have a 'threading.py' and a 'dummy_thread.py' in my /usr/local/lib/python2.4 folder and I only have one version of python installed. Can anyone help me with this? I've googled it and can't find any mention of a similar problem anywhere else. I've also been through the trac mailing-list, but it doesn't seem like a trac-specific problem. All/any help greatly appreciated dorian -- http://mail.python.org/mailman/listinfo/python-list

How did you install python? By default, if built from ports, it should pop up a configuration dialog in which one of the options is to enable thread support. If you have a bad configuration record, you can do a "make config" in /usr/ports/lang/python to re-create it. (if there's no such option, then maybe using threads with python is disabled in 4.x) -- http://mail.python.org/mailman/listinfo/python-list

That was the problem. thanks for the clarity - finally working. > How did you install python?

os.system() inside a thread problem
Hello,
my thread calls a program with os.system().
> os.system("/usr/bin/wine /path/to/ultima/online.exe")
Ultima Online is starting and i can enter commands and navigate through the
game with my keyboard. If I move the mouse over the Ultima Online window
Ultima Online crashes. (the mouse just need to overlap 1 pixel of the egde
of the window. titlebar inlcuded)
> /usr/bin/wine: line 55: 11675 Segmentation fault
Same with os.popen()
If I run os.system() outside the thread everything is working like expected.
Other programs (wine emulated and nativ) work inside and outside the thread.
Can anyone tell me how I can fix this?
Google told me simillar problems were fixed by upgrading to python 2.4. that
is no option for me.
Thanks,
Daniel
some example code:
from threading import Thread
runuo = StartUO(command)
runuo.start()
class StartUO(Thread):
def __init__(self,command):
Thread.__init__(self)
self.command = command
def run(self):
os.execv(self.command)

in the example you included, you use execv. which one is it?

just curious: do you really have to use a thread? why not just do
os.system(command + "&")

I just wanted learn something about it and thought it would be a good start. I will use "os.system(command + "&")" as you said to solve the problem.

python's thread problem on Linux platform
I found that multi-threaded program(io-centralize ) runs very slowly on linux while the same program runs very quickly on windows.If I change the thread number to one ,the program runs quickly on linux, in fact the speed is quicker than the multi-threaded version . It turns out that python's multi-thread support on linux has some problems.Any comments? -- http://mail.python.org/mailman/listinfo/python-list

Python's thread/threading/Queue stuff is unfortunately Java-ish/ OS-mindset and not functional. Thus encourages screwing "ego threads". Maybe you get things organized frictionless with those 2? : http://aspn.activestate.com/ASPN/Cookbook/Python/Recipe/491281 http://aspn.activestate.com/ASPN/Cookbook/Python/Recipe/491280 -robert -- http://mail.python.org/mailman/listinfo/python-list
