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