This works on my machine and on the travis (both linux and osx https://travis-ci.org/MacPython/scipy-stack-osx-testing). Unfortunately the code currently snarfs all exceptions so this makes it hard to sort out what exactly is going wrong. > Yes, the "not found in the style library and input is not a valid URL or path” message is not exactly clear about that. Both with lynx and wget I am getting a warning about an invalid ssl certificate for that URL, so I need to explicitly override it or use ‘wget —no-check-certificate’. Curl seems to have some issues of its own, does not download the raw file anyway, though silently unless given ‘-v': > curl -v -O https://gist.github.com/adrn/6590261/raw * Hostname was NOT found in DNS cache % Total % Received % Xferd Average Speed Time Time Time Current Dload Upload Total Spent Left Speed 0 0 0 0 0 0 0 0 --:--:-- --:--:-- --:--:-- 0* Trying 192.30.252.143... 0 0 0 0 0 0 0 0 --:--:-- 0:00:02 --:--:-- 0* Connected to gist.github.com (192.30.252.143) port 443 (#0) 0 0 0 0 0 0 0 0 --:--:-- 0:00:03 --:--:-- 0* TLS 1.2 connection using TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA256 * Server certificate: *.github.com * Server certificate: DigiCert SHA2 High Assurance Server CA * Server certificate: DigiCert High Assurance EV Root CA > GET /adrn/6590261/raw HTTP/1.1 > User-Agent: curl/7.37.1 > Host: gist.github.com > Accept: */* > < HTTP/1.1 301 Moved Permanently < Content-length: 0 < Location: https://gist.githubusercontent.com/adrn/6590261/raw < Connection: close < 0 0 0 0 0 0 0 0 --:--:-- 0:00:03 --:--:-- 0 * Closing connection 0 > wget https://gist.github.com/adrn/6590261/raw --2015-02-09 01:38:16-- https://gist.github.com/adrn/6590261/raw Resolving gist.github.com (gist.github.com)... 192.30.252.143 Connecting to gist.github.com (gist.github.com)|192.30.252.143|:443... connected.

To connect to gist.github.com insecurely, use `--no-check-certificate’. I don’t know if this is only due to something peculiar with my proxy or cache settings, but the mpl error comes down to python2.7’s urllib rejecting this certificate >>> from urllib2 import urlopen >>> fp = urlopen('https://gist.github.com/adrn/6590261/raw') Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/sw/lib/python2.7/urllib2.py", line 154, in urlopen return opener.open(url, data, timeout) File "/sw/lib/python2.7/urllib2.py", line 431, in open response = self._open(req, data) File "/sw/lib/python2.7/urllib2.py", line 449, in _open '_open', req) File "/sw/lib/python2.7/urllib2.py", line 409, in _call_chain result = func(*args) File "/sw/lib/python2.7/urllib2.py", line 1240, in https_open context=self._context) File "/sw/lib/python2.7/urllib2.py", line 1197, in do_open raise URLError(err) urllib2.URLError: <urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:581)> (even when using ‘http://...' in the URL), while python3.4 urllib apparently has no problems with it: >>> from urllib.request import urlopen >>> fp = urlopen('https://gist.github.com/adrn/6590261/raw') >>> fp <http.client.HTTPResponse object at 0x10c782a90> >>> fp.read() b'axes.facecolor : adeade’ MacOS X’s own /usr/bin/python (2.7.6) works as well, and Safari displays that URL as encrypted with a trusted certificate from DigiCert SHA2 High Assurance Server CA. An obvious suspect would be the latter two using Mac OS X’s system ssl, which is OpenSSL 0.9.8za, while lynx, wget and fink python all use fink’s OpenSSL 1.0.2; on a Linux machine with OpenSSL 1.0.1e wget and python2.7 can resolve the URL as well (though curl doesn’t download anything there either). But Fink’s python3.4 is using the same OpenSSL 1.0.2 as it’s python2.7, and accepts the certificate as well!

Can you track this back any further to sort out what is going on?

But another library update in between broke a compatibility version; after rebuilding ffmpeg those tests are passing now. > > ====================================================================== > ERROR: Failure: AttributeError ('module' object has no attribute 'test_backend_qt4') > FAILED (KNOWNFAIL=372, SKIP=1, errors=7) > > The bunch of these look like something is very broken about the installation. AttributeErrors like that tend to mean that something in the imports of those test modules errors (and nose eats those errors). > Unfortunately yes, the actual error was a failing ‘import mock’, so the mock package just needs to be added to the test dependencies for the python2.7 flavour. With it installed, those 4 above pass as well, so I seem to be left with only the openssl problem. Thanks for the assistance! Derek |
