John J Lee <[EMAIL PROTECTED]> added the comment:
There already is a test for the breakage, but the patch changes the
expected output to match the new return value of .header_items():
- [('Foo-bar', 'baz'), ('Spam-eggs', 'blah')]
+ [('Foo-Bar', 'baz'), ('Spam-Eggs', 'blah')]
Code that previously worked fine, for example code that iterates through
.header_items() and does string comparisons on the header names, or does
"in" tests on the keys of dict(header_items), etc. will break, the
existence of .has_header() notwithstanding.
What is the purpose of this change? Can you explain how that justifies
breaking working code?
The alternative to this change is to leave the return value of
.header_items() unchanged. That could be done by performing case
normalisation at a later stage.
