[zypp-devel] resolving dependency chain of named installed packages
I'm working on zypp supprt for supermin, a helper for libguestfs which creates an appliance based on a list of package names. My current approach is to download all packages from the repo and pass the filename of downloaded rpm packages to the tool for further processing. It does something like this, which downloads over 100 packages in my local 11.4 installation: zypper --verbose --verbose --verbose \ --root $PWD/tmp/root \ --reposd-dir $PWD/zypp/repos.d \ --cache-dir tmp//cache-dir \ --pkg-cache-dir tmp/pkg_cache_dir \ --gpg-auto-import-keys \ --non-interactive \ install \ --auto-agree-with-licenses \ --download-only \ \ bash kernel-default mkinitrd The next step would be to make use of already installed packages. What I would like to have is something like this: $new_tool --names bash kernel-default mkinitrd And the output would the name of rpm packages required for the named packages, like the following would produce: find tmp/pkg_cache_dir -name "*.rpm" | xargs rpm -qp --qf '%{NAME}\n' If $new_tool would be able to just download missing dependencies of uninstalled packages and list all the remaining installaed packages, that would be even better. How can I achieve this? Is there already example code which can be reused?

Sorry, but I don't get if you are actually interested in downloading all these rpms, or if it would be sufficient to parse the todo list from zyppers xml output: # create an 'empty system' /tmp/foo rm -rf /tmp/foo mkdir /tmp/foo # add your repos to /tmp/foo zypper --root /tmp/foo ar \ http://download.opensuse.org/distribution/12.2/repo/oss oss # install zypper --root /tmp/foo --xml install --dry-run bash... Unless you actually installed packages below /tmp/foo, the system there is empty and the xml output contains a <to-install> node which conatins a list of <solvable> nodes for all items to be installed: <to-install> <solvable type="package" name="bash" edition="4.2-51.6.1" arch="x86_64" summary="The GNU Bourne-Again Shell">description</solvable> ... </to-install> -- cu, Michael Andres +------------------------------------------------------------------+ Key fingerprint = 2DFA 5D73 18B1 E7EF A862 27AC 3FB8 9E3A 27C6 B0E4 +------------------------------------------------------------------+ Michael Andres SUSE LINUX Products GmbH, Development, ma@suse.de GF:Jeff Hawn,Jennifer Guild,Felix Imendörffer, HRB16746(AG Nürnberg) Maxfeldstrasse 5, D-90409 Nuernberg, Germany, ++49 (0)911 - 740 53-0 +------------------------------------------------------------------+ -- To unsubscribe, e-mail: zypp-devel+unsubscribe@opensuse.org To contact the owner, e-mail: zypp-devel+owner@opensuse.org

Thanks, that goes into the right direction. I want the reuse the files from installed packages. For this its required to know what other installed packages 'bash' for example needs. This way I get to the list I would like to have, with an empty --root: env -u LANG LC_ALL=C zypper \ --root $PWD/tmp/root \ --reposd-dir /etc/zypp/repos.d \ --cache-dir tmp/cache-dir \ --pkg-cache-dir tmp/pkg_cache_dir \ --gpg-auto-import-keys \ --non-interactive \ --xml \ install \ --auto-agree-with-licenses \ --dry-run \ bash | awk '/^.solvable/ { print $3}' | cut -f 2 -d '"' bash bash-doc bundle-lang-common-en filesystem glibc info libbz2-1 liblzma5 libncurses5 libreadline6 libzio ncurses-utils readline-doc terminfo-base zlib Is there an easy way to get the same list of packages with just the rpm database?

AFAIK not. -- cu, Michael Andres +------------------------------------------------------------------+ Key fingerprint = 2DFA 5D73 18B1 E7EF A862 27AC 3FB8 9E3A 27C6 B0E4 +------------------------------------------------------------------+ Michael Andres SUSE LINUX Products GmbH, Development, ma@suse.de GF:Jeff Hawn,Jennifer Guild,Felix Imendörffer, HRB16746(AG Nürnberg) Maxfeldstrasse 5, D-90409 Nuernberg, Germany, ++49 (0)911 - 740 53-0 +------------------------------------------------------------------+ -- To unsubscribe, e-mail: zypp-devel+unsubscribe@opensuse.org To contact the owner, e-mail: zypp-devel+owner@opensuse.org

Replacing awk with xmlstarlet works like that: zypper ... --xml install ... | xml sel -t \ -m "stream/install-summary/to-install/solvable[@type='package']" \ -c "string(@name)" -n I think using an empty --root is a usable workaround to get the list of packages.
