From a249b3e6fd798935a02b769149c9791a6fa6ef16 Mon Sep 17 00:00:00 2001 From: David Kalnischkies Date: Thu, 21 Jan 2016 23:22:00 +0100 Subject: reimplement build-dep via apts normal resolver MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit build-dep was implemented by parsing the build-dependencies of a package and figuring out which packages to install/remove based on this. That means that for the first level of dependencies build-dep was implementing its very own resolver with all the benefits (aka: bugs) this gives us for not using the existing resolver for all levels. Making this work involves generating a dummy binary package with fitting Depends and Conflicts and as we can't create them out of thin air the cache generation needs to be involved so we end up writing a Packages file which we want to parse – after we have parsed the other Packages files already. With .dsc/.deb files we could add them before we started parsing anything. With a bit of care we can avoid generating too much data we have to throw away again (as many parts assume that e.g. the count of packages doesn't change midair), so that on a speed front there shouldn't be much of a difference, but output can be slightly confusing as if we have a completely valid cache on disk the "Reading package lists... Done" is printed two times – but apt is pretty quick about it in that case.
