It looks like zypper has no "ignore unknown packages/provides" flag.
zypper .. install $pkg is called with an unknown package then zypper
will just abort because it expects valid input.
Maybe there should be some code which iterates over "names" and lets
zypper check for every single pkg and drop the ones which it can not
resolve. Later the smaller "names" list can be passed to zypper.
Are other plugins more forgiving in this?
Yes. For example, the yum/RPM plugin does effectively this:
#!/usr/bin/python
import yum
import yum.misc
import sys
yb = yum.YumBase ()
yb.setCacheDir ()
patterns = ["bash", "notarealpackage"]
pkgs = yb.pkgSack.returnPackages (patterns=patterns, repoid=0)
for pkg in pkgs:
print pkg
... which prints (after ages, for yum is very slow):
bash-4.2.39-3.fc18.x86_64
bash-4.2.45-1.fc18.x86_64
This is a feature of supermin, because it lets you have package lists
that don't need to be heavily conditionalized based on the precise
version of a distro, especially when packages are often being renamed
(like util-linux -> util-linux-ng and back again).
