Subject SourceResolver in M3 and symbolic links
Date Mon, 07 Jul 2003 20:55:28 GMT
The latest version of excalibur.source.SourceResolver packaged 
with Cocoon-2.1m3 normalizes URIs containing "/foo/../bar" to "/bar".
At first sight this looks a good idea and is according to RFC 2396.

But when dealing with file: URIs foo can be a symbolic link
(aka short-cut) such as "foo -> some/where/else".  Following 
filesystem semantics, "/foo/../bar" results in "/some/where/bar".  
Used with care this can be a powerful feature, which got lost now.  
(My setup is currently royally screwed due to that.)

So is file:/foo/../bar going to stay a URI as per RFC 2396, or shall 
we have an exception to suppress the "<segment>/.." normalization
step for file:.

Cheers, Alfred.
