[arch-projects] [dbscripts] Expected behavior of db-remove?

[Luke Shumaker]

From: Luke Shumaker <lukeshu at parabola.nu>

Following is a test-case for db-remove demonstrating a case where I'm
not sure what the intended behavior is.  Note that the test-case is
identical to the existing "remove multiple packages" test-case, except
that 'pkg-single-arch' has been added to the pkgs=() array.  With
pacman 5.0, the test-case would have passed, but with pacman 5.1, the
test-case fails.

With the pacman 5.1 version of repo-remove, if any of the named
packages are not found, the entire transaction is aborted, and *no*
packages are removed.  With 5.0, it would have said "error", but still
proceeded to remove the other named packages.

So, in my test-case, because 'pkg-single-arch' is an x86_64 only
package (while the others are x86_64 and i686), db-remove succeeds on
x86_64, but fails to remove anything on i686 because pkg-single-arch
isn't present there.  Also note that despite saying "ERROR" and
failing to do anything, db-remove has a 0 exit-code; the test-case
failure doesn't happen until it calls checkRemovedPackage.

So, what's the desired behavior here?  Ignore packages that are
already missing from the repo, or abort if any of the named packages
aren't found?
