Mark Mielke commented on HTTPCLIENT-1995:
-----------------------------------------
If you are agreeing that it is a bug, and it will get attention in HttpClient
5.1+, but not HttpClient 4.5.x, and you are planning to move the HttpClient
5.1+ work to a new ticket, can you please change the status of this ticket from
"Invalid" to something else like "Needs Resources" or "Won't Fix", to indicate
you agree the bug is real?
My main concern is about the stance that it is "Invalid".
For example, let us say that somebody reading - myself, or one of the earlier
people affected - were to submit a fix to HttpClient 4.5.x, to correct the
regression, would it be accepted? If this issue says "Invalid", I am presuming
it will be rejected outright. If this issue says something else, then I'm
presuming it might be accepted.
> Percent-encoded ampersand in URI path not preserved
> ---------------------------------------------------
>
> Key: HTTPCLIENT-1995
> URL: https://issues.apache.org/jira/browse/HTTPCLIENT-1995
> Project: HttpComponents HttpClient
> Issue Type: Bug
> Components: HttpClient (classic)
> Affects Versions: 4.5.8, 4.5.9
> Environment: Linux Mint 19, OpenJDK 8
> Reporter: none_
> Priority: Major
>
> Starting with HttpClient 4.5.8, percent-encoded ampersand characters in URI
> path segments are not preserved any longer but written in decoded form to
> wire due to path normalization performed by URIUtils.rewriteURI(URI,
> HttpHost).
>
> According to RFC 3986 (page 11+), the ampersand character is a delimiter and
> thus needs to be percent-encoded when not used for this purpose. Path
> normalization, as performed by HttpClient v4.5.8+, creates a new URI that is
> not equivalent to the original URI and thus leads to misinterpretation on
> server/receiver side.
> ??URIs that differ in the replacement of a reserved character with its??
> ??corresponding percent-encoded octet are not equivalent. Percent-??
> ??encoding a reserved character, or decoding a percent-encoded octet??
> ??that corresponds to a reserved character, will change how the URI is??
> ??interpreted by most applications??.
>
> A very simple test case is as follows:
> {code:java}
> @Test
> public void testAmpersand() throws Throwable
> {
> final URI uri = new
> URI("http://example.org/some/path%26with%20percent/encoded/segments";);
> final URI uri2 = URIUtils.rewriteURI(uri, null);
>
> Assert.assertEquals(uri, uri2);
> }
> {code}
>
