"""Test proper handling of Content-Type headers.
|

|
|
encode_headers() must be called as late as possible before a
|
|
request is sent. If this principle is violated, and if any
|
|
changes are made to the headers between encode_headers() and the
|
|
actual request (for instance a call to
|
|
_set_common_request_kwargs()), and if you're trying to set a
|
|
Content-Type that is not equal to application/octet-stream (the
|
|
default), it is entirely possible that you'll end up with two
|
|
Content-Type headers defined (yours plus
|
|
application/octet-stream). The request will go out the door with
|
|
only one of them chosen seemingly at random.
|
|
|
|
This test uses a call to update() because it sets a header such
|
|
as the following (this example may be subject to change):
|
|
Content-Type: application/openstack-images-v2.1-json-patch
|
|
|
|
This situation only occurs in python3. This test will never fail
|
|
in python2.
|
|
|
|
There is no test against the CLI because it swallows the error.
