in thread Relative URI

He expects http://a.b.c/d/../e/ to be the same as http://a.b.c/e/.
If I read section 5.2 of RFC 3986 correctly, the OP quite rightly expects that to be.

    There is a violation of 5.2 elsewhere, though.

    use strict; use warnings; use Test::More tests => 1; use URI qw( ); # if defined(R.scheme) then # T.scheme = R.scheme; # T.authority = R.authority; # T.path = remove_dot_segments(R.path); # T.query = R.query; is( URI->new_abs('http://a.b.c/d/../e/', 'http://a.b.c/'), 'http://a.b +.c/e/' ); 1;
    1..1 not ok 1 # Failed test at a.pl line 8. # got: 'http://a.b.c/d/../e/' # expected: 'http://a.b.c/e/' # Looks like you failed 1 test of 1.

    I would except cannonical to implement 6.2.2.3. It does implement other similar rules.

    use strict; use warnings; use Test::More tests => 6; use URI qw( ); is( URI->new('hTtP://a.b.c/' )->canonical, 'http://a.b.c/', 'R +FC 3986, 6.2.2.1' ); is( URI->new('http://a.b.c/d/../e/')->canonical, 'http://a.b.c/e/', 'R +FC 3986, 6.2.2.3' ); is( URI->new('http://a.b.c' )->canonical, 'http://a.b.c/', 'R +FC 3986, 6.2.3' ); is( URI->new('http://a.b.c:' )->canonical, 'http://a.b.c/', 'R +FC 3986, 6.2.3' ); is( URI->new('http://a.b.c:/' )->canonical, 'http://a.b.c/', 'R +FC 3986, 6.2.3' ); is( URI->new('http://a.b.c:80/' )->canonical, 'http://a.b.c/', 'R +FC 3986, 6.2.3' ); 1;
    1..6 ok 1 - RFC 3986, 6.2.2.1 not ok 2 - RFC 3986, 6.2.2.3 # Failed test 'RFC 3986, 6.2.2.3' # at a.pl line 10. # got: 'http://a.b.c/d/../e/' # expected: 'http://a.b.c/e/' ok 3 - RFC 3986, 6.2.3 ok 4 - RFC 3986, 6.2.3 ok 5 - RFC 3986, 6.2.3 ok 6 - RFC 3986, 6.2.3 # Looks like you failed 1 test of 6.

    5.2 describes how to make an absolute uri from a (possibly) relative URL.

    In that context, "/d/../e/" is equivalent to "/e/", but the module already does that correctly.

    Update: 6.2.2.3 seems more relevant here.
