From 7a948ec719ecc020c2337fe3f41c5fc42699e2c1 Mon Sep 17 00:00:00 2001 From: David Kalnischkies Date: Wed, 26 Jun 2013 17:37:57 +0200 Subject: [PATCH] Version 3 for DPkg::Pre-Install-Pkgs with MultiArch info Adds on top of Version 2 to all displayed version numbers the architecture as well as the MultiArch flag for consumption by the hooks. Most of the time the architecture will be the same for both versions displayed, but packages might change from "all" to "any" (or back) between versions so we can't display the architecture for packages. Pseudo-Format for Version 3: Examples: stuff - - none < 1 amd64 none **CONFIGURE** libsame 1 i386 same < 2 i386 same **CONFIGURE** stuff 2 i386 none > 1 i386 none **CONFIGURE** libsame 2 i386 same > - - none **REMOVE** toolkit 1 all foreign > - - none **REMOVE** Closes: #712116 --- apt-pkg/cacheiterators.h | 1 + apt-pkg/deb/dpkgpm.cc | 71 ++++++++++---- apt-pkg/deb/dpkgpm.h | 4 +- apt-pkg/pkgcache.cc | 12 +++ doc/apt.conf.5.xml | 14 ++- ...12116-dpkg-pre-install-pkgs-hook-multiarch | 95 +++++++++++++++++++ 6 files changed, 171 insertions(+), 26 deletions(-) create mode 100755 test/integration/test-bug-712116-dpkg-pre-install-pkgs-hook-multiarch diff --git a/apt-pkg/cacheiterators.h b/apt-pkg/cacheiterators.h index 179a0e963..886d84838 100644 --- a/apt-pkg/cacheiterators.h +++ b/apt-pkg/cacheiterators.h @@ -220,6 +220,7 @@ class pkgCache::VerIterator : public Iterator { inline VerFileIterator FileList() const;
