Let's have the serializer just worry about serializing the dict
that we hand it, and move the unicode stuff up to a serialize module.
This should hopefully let us move toward using a version string in
cassettes.
There is a weird quirk in HTTP. You can send the same header twice.
For this reason, headers are represented by a dict, with lists as the
values. However, it appears that HTTPlib is completely incapable of
sending the same header twice. This puts me in a weird position: I want
to be able to accurately represent HTTP headers in cassettes, but I
don't want the extra step of always having to do [0] in the general
case, i.e. request.headers['key'][0]
In addition, some servers sometimes send the same header more than once,
and httplib *can* deal with this situation.
Futhermore, I wanted to keep the request and response cassette format as
similar as possible.
For this reason, in cassettes I keep a dict with lists as keys, but once
deserialized into VCR, I keep them as plain, naked dicts.
Add the ability to filter out sensitive data, using one of three
methods: from headers, from a query string, and by using a custom
callback to modify the request.
Closes#67
Before this change, vcrpy would not work with modules of Boto (e.g., boto.iam)
that use Boto's CertValidatingHTTPSConnection to connect to AWS (unless you
went through the extra effort of disabling certificate validation during the
tests). This change adds support for those modules.
This test will fail with the following error:
TypeError: unbound method __init__() must be called with VCRHTTPConnection
instance as first argument (got CertValidatingHTTPSConnection instance instead)
The TypeError is raised because the __init__ method of Boto's
CertValidatingHTTPSConnection (which extends httplib.HTTPConnection) calls
httplib.HTTPConnection.__init__, and during the test httplib.HTTPConnection
actually refers to the patched verison (i.e., VCRHTTPConnection). When
VCRHTTPConnection.__init__ is called, it expects to receive a
VCRHTTPConnection object as its first argument, but instead it receives a
CertValidatingHTTPSConnection object. Because the only ancestor class of
CertValidatingHTTPSConnection is the original, un-patched
httplib.HTTPConnection, the first argument is not considered to be a
VCRHTTPConnection object, so a TypeError is raised.
