Description

This change works to standardize how we store headers, both for requests
and responses, in the new hosting service HTTP implementation. We now
store all headers as lowercase, and normalize on lookup.

HostingServiceHTTPResponse now has a get_header() method, just like
HostingServiceHTTPRequest. This is now preferred over accessing
headers directly, and will handle normalization on the caller's
behalf. This is future-proof and avoids any further confusion around
headers.

Testing Done

Unit tests pass on Python 2.7 and 3.6 through 3.8.

Add header normalization and fetching for hosting service HTTP support. We've had some annoyances with properly looking up headers from an HTTP response in hosting service implementations in a consistent manner across versions of Review Board, and across versions of Python. Work has been done to fix this for GitHub, where this was more immediately noticed.

The first and third Authorization header tests are the same test.
The Content-length header tests are the same too.
Let me know if this is done on purpose.

Oops, definitely not! They were supposed to be lowercased. I did something wrong for sure. Good catch!

chipx86 Sept. 25, 2020, 1:05 a.m.

That is, the 3rd one was supposed to be lowercase. The 2nd was supposed to be all caps.

Change Summary:

Fixed some bad variations on HTTP headers in the unit tests.
