Subject Re: Authentication patch
Date Wed, 22 Jan 2003 19:18:07 GMT
Note: Taking discussion to xml-rpc-dev list.

For Dejan:

We have a short page on our site on contributing to the XML-RPC project:

There are several things we like to see accompanying your contribution:
1. A feature request / bug report on  Anyone 
can register for a free account.   If not, a post to the dev list 
( with [PATCH] in the title will work as well.
2. A clear and concise description of the problem you are trying to 
solve.  Your web site has this information, but it is more of a nice 
piece of documentation of your code than a description.  Put this 
description in the bug report, it will eventually end up in changes.xml.
3. A unit test that fails before your patch is applied and passes 
afterwards.  For new features, the fact that the unit test doesn't 
compile before your patch is OK.

For the other developers:
OK I took the time to read this.  It seems like the point of it is this 
(taken from the page):

can make a call to any public method

And the substantive change to the code is here:

+                else if (handler instanceof AuthenticatedHandler)
+                {
+                        if (((AuthenticatedHandler)handler).authenticate(user, password))
+                        {
+                                Invoker invoker = new Invoker(handler);
+                                outParam = invoker.execute(methodName, inParams);
+                        }
+                        else
+                        {
+                                throw new XmlRpcException(0, "Username or password does not
+                        }
+                }

If we don't hear from Dejan again soon I will put this in nagoya and 
take it from there.
