* bug#22817: 25.0.91; [PATCH] Include versioned preloaded libraries in `package--builtin-versions'

Currently `package--builtin-versions' does not contain versioned preloaded
libraries (cl-generic, tabulated-list), which makes package.el believe they're
not builtin and install the versions from ELPA.  This patch fixes the problem.

Also, since `package--builtin-versions' is now complete, should we remove the
version info in `package--builtins'?

I forgot to mention that the bug can be reproduced by installing a
package having a preloaded lib as a dependency, e.g.:

  M-x package-install RET xelb RET

Then cl-generic 0.2 will get installed.

Not sure what you mean nor what would be the benefit.

A more direct way is to check (assq 'cl-generic package--builtin-versions)
which should not return nil (but does :-( ).

I haven't looked in detail at your patch, but it'd be good to do
something along these lines.

It's probably too late to use your approach for emacs-25, but I think we
need to install some fix for this problem in emacs-25, since otherwise
Emacs-25.1 will end up insisting on installing cl-generic from GNU ELPA
every occasion it gets.

How 'bout you install your patch into master and we install the patch
below into emacs-25?

I just noticed you wrote this in finder.el:

    ;; FIXME: Now that we have package--builtin-versions, package--builtins is
    ;; only needed to get the list of unversioned packages and to get the
    ;; summary description of each package.

That'd be okay.

I think we can simply drop the version info in `package--builtins' /
`package--bi-desc' so as to eliminate duplicated info and prevent
future confusion.  Also the variables are only used in a few places so
it'd be easy to make the change.

I'm not completely sure the end result will be simpler/cleaner, but
I guess it's worth a try.

I've installed this patch into master.  It turns out
`package--builtins' and `package--bi-desc' cannot be elegantly cleaned
up so I just give up the idea.

I'm not quite clear on the impact of this patch, so I defer to Eli on this
one.
