Hello! After a day of various attempts yesterday, I managed to get cython installed on my windows 10 machine.
Allow me to prefix this by saying, if there is somewhere else I should put this, II'M SORRY! So I ran cython on my python project, and it worked fine, there was one error about an int, which I have put at the end of this document. In summary though I don't think it has any relevance, might be me though. Here's the problem. In my program, when you load a new feed, the program launches a separate thread for using feedparser to download the rss feed, like this: def loadfeed(feed): # do the feed loading code here # play a sound to say the feed was loaded the loadfeed function is called through the threading module. I put some print statements in, to establish what is going on in cython. According to what I see, it launches the thread fine, it starts, and then it gets to this line: newfeed=feedparser.parse(url) And just, stops. I admit, it could be a speed problem, as I've not had the patients to let it run past about a minute, but in the normal, uncythonised python code, it runs in between 1 and 5 seconds, based on size of feed. It doesn't error, it just acts like it has frozen. The thread doesn't disappear, because the little status checker I have set up to keep an eye on threads within the program says it is still running, it just... seems not to. I know this because, after the line above, I then have: print '2' Which it never does. I was wondering if there is a common cython... thing, I have missed here, where you have to compile feedparser separately? not at all? or something. My worry is not speed, in this instance, 1 to 5 seconds is fine, all things considered and it being in a separate thread... I'm unworried at those timings. My aim with cython was a simple, but nice enough, layer of protection That being said, in my research I had read about the gil? Or something similar to do with only one python thread running at any one time in cython? I admit to not understanding this, though. Any explanations anyone can offer here would be greatly appreciated. Thank you very much. A confused Nate.
