Subject [jira] Updated: (HTTPCLIENT-658) Custom Protocol in HostConfiguration ignored
Date Fri, 15 Jun 2007 19:34:26 GMT

     [ https://issues.apache.org/jira/browse/HTTPCLIENT-658?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Roland Weber updated HTTPCLIENT-658:

      Priority: Minor  (was: Major)
    Issue Type: Improvement  (was: Bug)

Firstly, this is not a bug. It has been documented several times on the mailing list and in
the bug tracking system that setting the scheme handler in the HostConfiguration will only
work for relative URLs. Bugs are deviations from intended or documented behavior, not things
that work differently from what somebody expected. This is a feature request, and I'll grant
that it is an improvement.
Secondly, this is not major. As far as I can tell, in HTTPCLIENT-634 John Kristian provided
us with a solution to this problem that does not affect the default behavior. A previous lack
of test coverage is not a good argument for changing default behavior that late in the release

Before I agree to this change, I would like to see discussion of two questions:
1) What and how many applications might be affected by this change? Over the years, we've
told a lot of people that it will only work for relative URLs. Has anyone written an application
that _relies_ on this behavior?
2) If we apply this patch, how can an application switch back to the current behavior? Ignoring
a method call by providing a custom HostConfiguration implementation is easy, but how do you
act on a method _not_ being called?

The second question is independent of the first one. Even if we can't think of any reason
for an application to rely on the scheme handler being reset, we must not change the behavior
between RC1 and final unless we can tell people how to get back to the original one. Respectfully,
I am -0 on this change.

> If you you do not register a custom Protocol as scheme default handler but set it in
HostConfiguration, it will be ignored if the URL given to a Method instance is absolute.
> HttpClient will then override it by calling hostconfig.setHost(uri).
