Comment:
I was able to get things working by causing Mac OS X's auto-detection of
proxy information to be skipped. This possibility is mentioned
[https://docs.python.org/3/library/urllib.request.html#urllib.request.ProxyHandler
here] in CPython's `urllib.request.ProxyHandler` documentation.
More detailed instructions appear in `urllib.request`'s module docstring.
To disable the auto-detection, I followed the instructions in the above-
mentioned module docstring and modified `LiveServerBase.urlopen()` to look
like the following (this is just a proof of concept):
{{{#!python
def urlopen(self, url):
import urllib.request
# Pass an empty dictionary to disable auto-detecting the proxy.
proxy_support = urllib.request.ProxyHandler({})
opener = urllib.request.build_opener(proxy_support)
urllib.request.install_opener(opener)
return urlopen(self.live_server_url + url)
}}}
After doing this, the following command worked fine:
{{{
$ ./runtests.py servers.tests
}}}
Since this seems like a fundamental bug / limitation on Mac OS X (in at
least some versions), it seems worth considering including Mac-specific
code to enable the parallel running of tests on this platform.
