Hi Hackers,
the support for *path* in repositories (the piece appended to baseurl) is still not perfect in libzypp. I am about to fix it, but first i've got a few questions.
- DO WE NEED THIS AT ALL? :O)
AFAICT, we needed this for multi-product media (like patch-CDs probably). I'm not sure why, though, can't we just go about it with two different URLs? If some 'conent' file references the other repo with a relative path, it should be no problem for libzypp to just use the baseurl+this_path, no need to treat them separately(?).
To handle a media set we need to to know 2 urls. 1) the media root - This is the location of media.<n>/media. We need it to check e.g whether the correct media is inserted. There are also other files like the gpg-keys, releasenotes,.. kept in the media root directory and not per repository. - In case you copy a media set to your disk (to offer it via http, nfs,...) /somewhere/DVD1 /DVD2 ... /DVD<N> this is the place where you have to change DVD1 to DVD2 when changing from media 1 to 2. 2) the repositories root on the media This is the path to acces the repository on the media. If the media has just one repo at /, you don't need the path. Libzypp could live without 'path'. We could simply guess the media root when changing or verifying media. For CD/DVD it's obvious. And for disc copies we could probe for a ending in digits, or for a media.<n> directory. But you also have to adapt YaST (and maybe other tools), which currently expect the url pointing to the media root. They download e.g repo.url()/control.xml Or we have to change the media layout an keep certain files per repo and not per media. This might even be reasonable, but... It's not a zypp local change. If we want to go for this, we have to convince some people. But it could be worth trying to do this.
Is the 'path' part of YUM's definition?
AFAIK not. It's not needed if you don't deal with media sets the way we do it. 'path' is actually part of the media handling, not of the repo.
- our repository definition allows multiple baseurls to be defined, as well as mirrors (these are ignored currently IIRC). What to do with this:
[foorepo] baseurl = http://url1.org/repos baseurl = http://url2.org/whatever path = foorepo/openSUSE/11.1
not to mention mirrors. Should we just use the path for all of the baseurls?
We have to. We must assume all urls point to locations with the same layout (not just same content). And in most cases you dont need the path as it's /. -- cu, Michael Andres +------------------------------------------------------------------+ Key fingerprint = 2DFA 5D73 18B1 E7EF A862 27AC 3FB8 9E3A 27C6 B0E4 +------------------------------------------------------------------+ Michael Andres YaST Development ma@novell.com SUSE LINUX Products GmbH, GF: Markus Rex, HRB 16746 (AG Nuernberg) Maxfeldstrasse 5, D-90409 Nuernberg, Germany, ++49 (0)911 - 740 53-0 +------------------------------------------------------------------+ -- To unsubscribe, e-mail: zypp-devel+unsubscribe@opensuse.org For additional commands, e-mail: zypp-devel+help@opensuse.org
