Issues List for the
URI Test Cases and Implementation Reports

The examples provided in the specification (section 5.4) use a base
URI of "http://a/b/c/d;p?q" and should be consistent with almost all
implementations.  A rel_examples1
Test Page is provided for visual testing.  Note that this is only
a test of the URI reference parser and conversion to absolute form.

I have created a testing page at http://www.w3.org/2004/04/uri-rel-test.html
to make (manual) testing of the implementations in various browsers easy.

I have added some more tests to my page at

   http://www.w3.org/2004/04/uri-rel-test.html#reg-percent

What they test is whether %hh in reg-name is dealt with according
to the spec. There are two parts, one for cases that correspond
to US-ASCII only, and the other for cases that correspond to IDN.

This simple perl script was used by Roy to test the algorithms described
within the specification.  Usage:

  cat list-of-URI-refs.txt | perl uri_test.pl "base-URI"

Here are examples of its input and output when given the
base URI of "http://a/b/c/d;p?q".

Roy tested the URI reference parser on Apple Safari 1.0.2 by simple
observation of the test cases.  The results were consistent with
those of rfc2396bis except in that Safari will add a default path
of "/" to http URIs that have an empty path.  Since that is consistent
with a scheme-specific optimization, Safari 1.0.2 is compliant.

I have used this page to test Amaya (my version, compiled from CVS
checkout on 2004-01-04). I don't know whether (or to what extent)
processing is done by Amaya or by libwww. Here are the results:

All tests are passed, except the following:

#       rel             correct                 Amaya

6       //g             http://g                http://g/ (additional slash)
7       ?y              http://a/b/c/d;p?y      http://a/b/c/?y (d;p removed)
9       #s              http://a/b/c/d;p?q#s    {testpage URI}#s
15                      http://a/b/c/d;p?q      not tested
43      g.              http://a/b/c/g.         http://a/b/c/g (dot removed)
51      ./../g          http://a/b/g            http://a/b/c/g (/c not removed)
55      g;x=1/./y       http://a/b/c/g;x=1/y    http://a/b/c/g;x=1/./y
                                                        (precedence of ; over /)
56      g;x=1/../y      http://a/b/c/y          http://a/b/c/g;x=1/../y
                                                        (precedence of ; over /)

For test 71, Amaya uses strict parsing.

All tests are passed, except the following:

#       rel             correct                 Amaya

6       //g             http://g                http://g/ (additional slash)
9       #s              http://a/b/c/d;p?q#s    {testpage URI}#s
15                      http://a/b/c/d;p?q      not tested
51      ./../g          http://a/b/g            http://a/b/c/g (/c not removed)

For test 71, Opera uses backwards-compatible parsing.

All tests are passed, except the following:

#       relative        absolute                Link checker

6       //g             http://g                http://g/  (added slash)
7       ?y              http://a/b/c/d;p?y      http://a/b/c/?y  (missing d;p)
31      ../../../g      http://a/g              http://a/../g    (leftover ../)
32      ../../../../g   http://a/g              http://a/../../g (leftover ./../)
41      /./g            http://a/g              http://a/./g     (leftover ./)
51      ./../g          http://a/b/g            http://a/b/c/g   (leftover c/)

For test 71, the link checker uses strict parsing.

#       rel             correct                 Firefox 0.8

6       //g             http://g                http://g/
15                      http://a/b/c/d;p?q      not testable
51      ./../g          http://a/b/g            http://a/b/c/g
71	http:g					http://a/b/c/g
