Description Ales Kozumplik 2013-05-20 13:32:56 UTC

It looks besides substituting variables in mirrorlist URLS and baseurls, Yum is able do $basearch and $releasever substitutions in the mirrorlists itself, e.g when one downloads mirrorlist containing the following entries:

http://mirror.unl.edu/kde-redhat/fedora/$releasever/$basearch/stable
http://ftp.heanet.ie/pub/kde-redhat/fedora/$releasever/$basearch/stable
http://apt.kde-redhat.org/apt/kde-redhat/fedora/$releasever/$basearch/stable
http://kdeforge.unl.edu/apt/kde-redhat/fedora/$releasever/$basearch/stable
http://kdeforge2.unl.edu/kde-redhat/fedora/$releasever/$basearch/stable

It replaces all $releasever and $basearch with proper string before issuing a HTTP request to one of the mirrors.

Several approaches toward implementing this in librepo can be considers of which, I'd like to point out, a callback mechanism seems the least practical to me. Perhaps passing the handler list of substitutions beforehand?

Fixed in https://github.com/Tojaj/librepo/commit/a97530214cc39f1a63f51ca76baa9a8640d03bfb

Add option LRO_VARSUB.

Example of usage:

h = librepo.Handle()
h.varsub = [("releasever", "18"), ("basearch", "i386")]

Looks good. Tomas, could you roll a new release with this functionality included into Fedora rawhide please. librepo isn't really usable without LRO_VARSUB unless you like butchering your .repo files with sed :).

Hi, new build is done (http://koji.fedoraproject.org/koji/buildinfo?buildID=426150).
