James M Snell resolved ABDERA-225.
----------------------------------
Resolution: Fixed
Fix checked in
> At ("@") and colon (":") in path segments should not be escaped by
> IRI.normalize()
> ----------------------------------------------------------------------------------
>
> Key: ABDERA-225
> URL: https://issues.apache.org/jira/browse/ABDERA-225
> Project: Abdera
> Issue Type: Bug
> Affects Versions: 0.4.0
> Reporter: Niklas Lindström
>
> The `normalize` method on IRI objects escapes ":" and "@" in path segments,
> which doesn't seem to comply with the ABNF rules given in the IRI RFC (RFC
> 3987 section 2.2. <http://tools.ietf.org/html/rfc3987#section-2.2>).
> It seems that `isegment` explicitly *allows* for ":" and "@", according to:
> isegment = *ipchar
> ...
> ipchar = iunreserved / pct-encoded / sub-delims / ":" / "@"
> The `normalize` method encodes each segment by filtering on
> `CharUtils.Profile.IPATHNODELIMS`, via `CharUtils.is_ipathnodelims`, which
> uses `is_ipath` && `!isGenDelim`.
> The effect is that this (groovy):
> import org.apache.abdera.i18n.iri.IRI
> println new IRI("http://example.org/publ/1999:175";).normalize()
> println new IRI("http://example.org/people/[email protected]";).normalize()
> prints out:
> http://example.org/publ/1999%3A175
> http://example.org/people/admin%40example.org
> , where I would expect no escaping at all. Note that:
> println new java.net.URI("http://example.org/publ/1999:175";).normalize()
> println new
> java.net.URI("http://example.org/people/[email protected]";).normalize()
> results in the expected:
> http://example.org/publ/1999:175
> http://example.org/people/[email protected]
> Since an ipath is composed of "/"-separated isegments (with some specifics
> regarding absolute, rootless and noscheme), perhaps a solution would be to
> rework `is_ipath` into calls fully mimicking these ABNF rules, and use
> `UrlEncoding.encode(..., Profile.IPATH.filter())` in `IRI.normalize(path)`?
