Am I wrong in remembering that old packages get dropped from the
simple index?
I'm not saying they get deleted from the server, but they are made
unavailable to easy_install without special knowledge of how to get
them, Â So old packages can have requirements in setup.py which become
unavailable  for simple install.
If you give pip or easy_install (or I assume buildout) a requirement
like Foo==0.1, then they will look at
<http://pypi.python.org/simple/Foo/0.1>http://pypi.python.org/simple/Foo/0.1,
easy_install doesn't do that, unless you explicitly add that URL via
-f or --find-links. Is that a feature you added in pip?
and if the release is hidden that will still return the links for
that version of the package. If you give a version like Foo<=0.1
then it won't work (assuming 0.1 is hidden), as there's no deep link
that either installer will look at.
A weird case is that links in long_description in old releases will
show up regardless, so if you actually want to purge a link (e.g.,
to a non-existent repository) then it require editing all versions
of the package. This might be unintentional.
It's at least consistent -- all URLs for all versions (whether hidden
or not) show up when you access the packagewide page.
There was some discussion in the past about whether this was
appropriate; IMO it's not, as it was an effective API change from the
pre-/simple days. Before, if a release was hidden, there was no way
for easy_install to find it except via explicit -f usage. Now, there
is no way for an author to hide a release from automatic installation
and still allow for manual installation.
