Subject [jira] Created: (HTTPCLIENT-588) relative URIs with internal double-slashes ('//') misparsed
Date Fri, 16 Jun 2006 01:58:29 GMT
relative URIs with internal double-slashes ('//') misparsed

         Key: HTTPCLIENT-588
         URL: http://issues.apache.org/jira/browse/HTTPCLIENT-588
     Project: Jakarta HttpClient
        Type: Bug

  Components: HttpClient  
    Versions: 3.0.1    
    Reporter: Gordon Mohr

URI.parseUriReference()'s heuristic for interpreting URI parts is thrown off by relative URIs
which include an internal '//'. As a result, portions of the supplied relative URI (path)
can be lost. 

For example:

URI rel = new URI("foo//bar//baz");
(java.lang.String) //bar//baz

The culprit seems to be line 1961 of URI improperly concluding that two slashes later than
the beginning of 'tmp' are still indicative the URI is a 'net_path'. 

A possible quick fix might be to add a '!isStartedFromPath &&' to the beginning of
the line 1961 test, making the line:

            if (!isStartedFromPath && at + 2 < length && tmp.charAt(at
+ 1) == '/') {

... and thus preventing the misguided authority-parsing from happening when earlier analysis
already identified the current string as a strictly path-oriented URI.

(It also appears the setting of the is_net_path boolean at the end of this if's block may
be wrong; this code is run for hier_path URIs that are not net_paths in the 2396 syntax. For

URI uri = new URI("http://www.example.com/some/page");
 (boolean) true
