[Yum] Using yum against password protected http repositories

[Ryan Tomayko]

I think I found it. It looks to be a yum/urlgrabber issue.

urlgrabber.py:
<<
  # should we be using urllib.splituser and splitpasswd instead?
  user_password, host = string.split(host, '@', 1)
  user, password = string.split(user_password, ':', 1)
  auth_handler.add_password(None, host, user, password)
>>

See how we're using string.split on user_password? That isn't doing any
url unescaping. So when we add the user/password to the auth handler, it
contains the escaped text (p%40ssword instead of p at ssword). The funny
thing is that Michael has a comment on using splituser/splitpasswd
instead, which does do unescaping and is probably the best way to fix
this. I remember seeing that comment in some of my recent urlgrabber
work and thinking that string.split should work fine, not to worry about
it. :/

I'll put something in bugzilla, send up a patch for yum2.0.5 and fix
this in the new urlgrabber cvs as well.
