Following up on issue 033, the following equation is an
important test of consistent implementations:
resolve_relative_URI(compute_relative_URI(u, base), base) = u
To satisfy this for all examples in section 5.4 of rfc2396bis-02,
a change in the algorithm of section 5.2 is required.
The change is needed to ensure that the ./ and ../ processing
is applied even when a relative URI is a path starting with "/".
In my implementation:
if R_path[0] == "/": T_path = merge('', R_path[1:])
A parser and URI processing algorithms that pass all the tests
are available for examination and comment at the following URL.
http://www.cs.sfu.ca/~cameron/uri/URIbis2.py
The parser is based on abnf2re and the algorithms include
compute_relative_URI as described yesterday, with one bug fix
to handle the authorityless relative URI.
The test program is available as well.
