[Pyobjc-dev] Threads and Queue

[Justin M. <ju...@th...>]

Hey All,

I am a little new to both Python and PyObjC. So please be gentle if I am 
missing something obvious :)

I have a project, most of which is written in Objective-C. In an effort 
to cut down on the amount of code I have to write and to take advantage 
of Python's large library, I have implemented one of my model's objects 
in Python. This was  easily done, by following examples, including the 
glue code etc..

But now I have run into some troubles with threading. In an effort to 
understand threading in python, I have cut and pasted the 'WorkerThread' 
class (found in Examples/WebServicesTool), this class has functionality 
similar to my needs (later when I understand what is happening I will 
make a thread pool class).  However, the thread function is only rarely 
scheduled to execute.

It seems to be a problem with Queue. The actual thread function runs OK, 
and waits on the queue. But when an item is placed on the Queue, via 
scheduleWork(), only rarely does queue.get() return in the thread, 
allowing it to run.

Is there something I should be doing before I use threads in PyObjC? 
Some obj-c runtime function I should be calling? Some python function?

Thanks in advance,

Justin
