We use Mercurial for our source control, hosted by BitBucket. It's easy to branch off the main repository and contribute patches, tests, and documentation back upstream.
No registration is required. Please be sure to report bugs as effectively as possible, to ensure that we understand and act on them quickly.
This is a simple web “crawler” that fetches a bunch of urls using a coroutine pool. It has as much concurrency (i.e. pages being fetched simultaneously) as coroutines in the pool.
urls = ["http://www.google.com/intl/en_ALL/images/logo.gif", "https://wiki.secondlife.com/w/images/secondlife.jpg", "http://us.i1.yimg.com/us.yimg.com/i/ww/beta/y3.gif"] import eventlet from eventlet.green import urllib2 def fetch(url): return urllib2.urlopen(url).read() pool = eventlet.GreenPool() for body in pool.imap(fetch, urls): print "got body", len(body)
