Now that we no longer support py27, we can use the standard library unittest.mock module instead of the third party mock lib. Change-Id: I446ee142c7a17446372c910f7f2a36d55df18e04 Signed-off-by: Sean McGinnis <sean.mcginnis@gmail.com>
Hiding the unhandled exception in the test with a failure makes it harder to debug the problem. Let them pass unhandled so the test reports an ERROR instead of FAILURE. Change-Id: I4e435a6d276fdf161dac28f08c2c7efedd1d6385 Signed-off-by: Doug Hellmann <doug@doughellmann.com>
This requests commit [1] changed the behavior when a nonexistent cacert file is passed in: now it raises IOError. This is getting through glanceclient.common.http.HTTPClient._request, which used to raise CommunicationError in this scenario. Even though there is arguably a better exception than CommunicationError to represent this condition (like maybe IOError), for backward compatibility this change set converts IOError to CommunicationError. We also improve the unit test to raise the original exception if the expected conditions aren't met; this improves debugability.

Due to the change in python versions greater then 2.7.8, messages that SSL certificate handling module is producing are different from the error messages produced in earlier versions of py27. Fixed how the following test cases of TestHTTPSVerifyCert class are handling erroneous SSL certification messages: - test_v2_requests_valid_cert_no_key - test_v2_requests_bad_cert - test_v2_requests_bad_ca Closes-Bug:1499355 Change-Id: I3b939292ba0042bced5cc91a26e2593450f9cafe
Custom SSL handling was introduced because disabling SSL layer compression provided an approximately five fold performance increase in some cases. Without SSL layer compression disabled the image transfer would be CPU bound -- with the CPU performing the DEFLATE algorithm. This would typically limit image transfers to < 20 MB/s. When --no-ssl-compression was specified the client would not negotiate any compression algorithm during the SSL handshake with the server which would remove the CPU bottleneck and transfers could approach wire speed. In order to support '--no-ssl-compression' two totally separate code paths exist depending on whether this is True or False. When SSL compression is disabled, rather than using the standard 'requests' library, we enter some custom code based on pyopenssl and httplib in order to disable compression. This patch/spec proposes removing the custom code because: * It is a burden to maintain Eg adding new code such as keystone session support is more complicated * It can introduce additional failure modes We have seen some bugs related to the 'custom' certificate checking * Newer Operating Systems disable SSL for us. Eg. While Debian 7 defaulted to compression 'on', Debian 8 has compression 'off'. This makes both servers and client less likely to have compression enabled. * Newer combinations of 'requests' and 'python' do this for us Requests disables compression when backed by a version of python which supports it (>= 2.7.9). This makes clients more likely to disable compression out-of-the-box. * It is (in principle) possible to do this on older versions too If pyopenssl, ndg-httpsclient and pyasn1 are installed on older operating system/python combinations, the requests library should disable SSL compression on the client side. * Systems that have SSL compression enabled may be vulnerable to the CRIME (https://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2012-4929) attack. Installations which are security conscious should be running the Glance server with SSL disabled.

This commit enables new flake8 checks: * E265 block comment should start with '# ' * H405 multi line docstring summary not separated with an empty line * E123 closing bracket does not match indentation of opening bracket's line * H238 old style class declaration, use new style (inherit from `object`) * E128 continuation line under-indented for visual indent and makes related changes in the code.

Several tests with cert verification are broken. This code fixes it by setting right imports. Also some typos are fixed too. Change-Id: Ie014f90714c3dabee65459fd704dd11b1770c7de Closed-Bug: #1472234
