The problem is that the OSS repository contains more than 60.000 (!) packages. Iterating over dependencies of all packages will take lot of time, speed optimizations can help only a bit. In pkg-bindings we have Pkg.PkgQueryProvides() function (https://github.com/yast/yast-pkg-bindings/blob/3ed52e693ca6a79fd7ee6db41e024...) which handles the "Provides" RPM dependency in a very efficient way. I thought we could create a similar function (PkgQuerySupplements) which would handle the "Supplements" dependency used in by AutoYaST. Unfortunately libzypp does not support that, it only supports WhatProvides (https://github.com/openSUSE/libzypp/blob/master/zypp/sat/WhatProvides.h) and WhatObsoletes (https://github.com/openSUSE/libzypp/blob/master/zypp/sat/WhatObsoletes.h). So my proposal is: 1) Switch from "Supplements: autoyast(foo)" to Provides: Provides: autoyast-tag() Provides: autoyast-tag(foo) ("autoyast-tag" is just a proposal, feel free to suggest anything better ;-)) 2) In the code: a) first get packages providing "autoyast-tag()" using Pkg.PkgQueryProvides("autoyast-tag()"), that should return few packages (like a dozen or so) b) then for that few packages get all dependencies and find out that "autoyast-tag(.*)" details That should be both fast and memory efficient. -- You are receiving this mail because: You are on the CC list for the bug.
