Re: [softwaremgmt] Is 1-Click reliable?

I totally agree on the repository de-duping issue. This has been a problem from the beginning, and there's still no way to uniquely identify a repository based on the metadata stored in the repository. See https://bugzilla.novell.com/377568 , until this is resolved it's also difficult to solve some of the other issues you raise.
Good to know the problem is being worked on
Regarding which repository packages will be installed from. The handler will prefer packages from the repositories explicitly mentioned in the YMP itself over others that are present on the user's system. However, you are correct that there is currently no way to explictly specify which repository every single package comes from.
The problem is you must add the OSS repo since you don't know if the user already added it, and since what you are trying to archieve is a sustitution of OSS repo packages...
Repository priorities are not supported yet since there was no support in libzypp/yast for repository priorities at the time, it should be in the future.
Ok.
There are a couple of things you can use in the meantime to work around some of the problems you have noticed. One possibility is to work with the package maintainers to adjust the dependencies and package naming to create something uniquely available. eg. packman-foo. Another is to use the more powerful Pattern format and in the YMP simply specify to install the Pattern instead of a package. N.B. this will not work in 11.0 due to a regression in that version of libzypp where it didn't support rpm-md patterns https://bugzilla.novell.com/419947 . I understand this is fixed in 11.1, though I haven't had time to install 11.1 yet.
Yes, even in an _updated_ 11.0 system rpm-md patterns work. I must admit I never understood what patterns offer that a simple rpm metapackage doesn't, but looking into an example (http://novell.com/package/metadata/suse/pattern returns 404, I don't know where I can find a spec... even if I don't talk XML/XSD :-p ) it looks like they offer the same than 1-Click, limited to a single repo, plus "recommends" and "suggests". I _suppose_ that even if just package names are provided, ZYpp will select packages only from the same repo the pattern comes from, true? If so, would be a good idea to talk with Packman... but, how can patterns.xml be created? http://en.opensuse.org/Enhancerepo talks about patterns like something "planned", and so I suppose createrepo doesn't supports them. Right now a text editor is everything Packman has available to create patterns? -- To unsubscribe, e-mail: opensuse-softwaremgmt+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-softwaremgmt+help@opensuse.org

A pattern is an object that does not gets installed in your system, but can depend, recommend, suggest, obsolete, conflict with anything else so it can be used to trigger complex selections. For the pattern to exist, it has to be in some repo, that is the difference with 1Click, which can live on its own.

Not true, it depends on the package versions, the vendors, repo priorities and your system policies.

I haven't implemented patterns in enhancerepo because I don't have a good idea how to make the user input the data in order to generate the xml, so it is actually worth it, otherwise you can always write the xml by hand and use enhancerepo or modifyrepo to add it to the metadata ;-) Duncan -- To unsubscribe, e-mail: opensuse-softwaremgmt+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-softwaremgmt+help@opensuse.org

So the only difference with a rpm metapackage is that a pattern does not gets installed? I ask because Packman seems to prefer metapackages (they have amarok-packman, but no patterns).

Not true, it depends on the package versions, the vendors, repo priorities and your system policies.
So we still have the same problem? A pattern in the Packman repo with: <rpm:requires> <rpm:entry name="gstreamer-0_10-plugins-ugly" /> </rpm:requires> could install the gstreamer-0_10-plugins-ugly package from OSS instead of Packman?

OK, I don't have a good idea neither. But I was more worried about having to modify manually also repomd.xml, checksums included. If enhancerepo/modifyrepo allows to add a manually created patterns file it seems good enough to me. -- To unsubscribe, e-mail: opensuse-softwaremgmt+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-softwaremgmt+help@opensuse.org
