Research direction

Start with the mimeparse.quality entry point and reproduce both examples from the issue. Compare the results with the media-negotiation rules and examples in RFC 7231 and RFC 9110; done means parameter ordering no longer changes the result when the inputs are semantically equivalent.

Written by the indexing model from the issue text.

Description

Although much of the negotiation is dependent on the specific server logic, it feels that the current implementation does not always follow the spirit of the HTTP semantics as detailed in RFC 7231 (now superseded by 9110, but 7231 has IMHO clearer examples) and RFC 9110.

Cf

>>> mimeparse.quality('text/html;level=3', 'text/*;q=0.3, text/html;q=0.7, text/html;level=1,text/html;level=2;q=0.4, */*;q=0.5')
0.7
>>> # So far so good. text/html;level=3 does not match the ranges for level=1 and level=2, so we get the generic value (0.7).
>>> # Now, just change the order of the example:
>>> mimeparse.quality('text/html;level=3', 'text/*;q=0.3, text/html;level=1, text/html;q=0.7, text/html;level=2;q=0.4, */*;q=0.5')
