Re: setup: problems with local install

So yeah, I guess putting some complexity back in accessible() would work, or perhaps the attached?  (This doesn't do the right thing for a few packages, for reasons I'm still looking into...)

To be specific it was doing the wrong thing for those few packages with no source

  /* scan for local copies of package */
-void
+bool
  packagemeta::scan (const packageversion &pkg, bool mirror_mode)
  {
-  /* Already have something */
+  /* empty version */
    if (!pkg)
-    return;
+    return true;

So, this needs to be 'return false', as the empty version is always inaccessible, to get the same behaviour as before.

I've found another problem with local installs: If a package needs upgrading, then the chooser will offer the upgraded version for install, even if there's no archive available. As a result, the current version will get uninstalled, and then setup will discover that it doesn't have the archive to install the new version.

The problem occurs because packagedb::defaultTrust() is called after ScanDownloadedFiles() has already done its work. solution.update() and solution.trans2db() are called, and pkg->desired is set equal to an inaccessible version pv (which has been previously removed from pkg->versions).

I guess trans2db() should check that pv is in pkg->versions before acting on an install transaction for pv. And then we also have to make sure to ignore the erase transaction for the current version of pkg.

Alternatively, can we just remove an inaccessible packageversion from the libsolv pool, or at at least just tell libsolv that we don't want to install it?
