Thanks for reporting the problem.

Which platform is impacted by this issue ?

I have this problem with today's nightly on Mac.

Is this message on Slicer startup expected:

[SSL] Failed to load Slicer.crt

?

At the same time, the test is passing on the dashboard mac: http://slicer.cdash.org/testDetails.php?test=6859382&build=691530

Fixed in r24658
See http://viewvc.slicer.org/viewvc.cgi/Slicer4?view=revision&revision=24658

The problem is that the dashboard doesn't test the packaged application. It only run the tests within a build tree.

Aha! Thanks a lot!

I will close the issue once I confirm it is working in the nightly.

Unfortunately, the problem is still there. The missing cert error on startup is gone, but I am still unable to open https URLs.

Tested with today's nighty on Mac: 4.4.0-2015-10-23 r24659

Steps to reproduce:

import urllib2
urllib2.urlopen('https://services.cancerimagingarchive.net/services/TCIA/TCIA/query')

Traceback (most recent call last):
File "<console>", line 1, in <module>
File "/Applications/Slicer-nightly/Slicer.app/Contents/lib/Python/lib/python2.7/urllib2.py", line 154, in urlopen
return opener.open(url, data, timeout)

raise URLError(err)
URLError: <urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:590)>

From a terminal, could you then try something like:

export SSL_CERT_FILE=/path/to/Slicer.app/Contents/share/Slicer-4.4/Slicer.crt

Then:

open -a /path/to/Slicer.app

And let me know.

With explicit import, it works fine.

To clarify, when you mention with "explicit import", you mean that by first setting the env. variable "SSL_CERT_FILE", it works ?

Correct.

That last issue should be fixed in r24662
See http://viewvc.slicer.org/viewvc.cgi/Slicer4?view=revision&amp;revision=24662

I just confirmed that the generated MacOSX package now behave as expected:

factory@kitware:/Users/kitware/Dashboards/Nightly/Slicer-0-build/Slicer-build/_CPack_Packages/macosx-amd64/DragNDrop/Slicer-4.4.0-2015-10-25-macosx-amd64/Slicer.app/Contents> ./MacOS/Slicer -c "import urllib2;print(urllib2.urlopen('https://www.eff.org/https-everywhere').getcode())&quot;
200

Confirmed it is working now, thank you!
