From: Dan McGee This allows architecture to be multivalued. On x86-64 machines, this could be something like: Architecture = x86-64-v3 x86-64 We use the first specified Architecture value in mirrorlist $arch variable replacement, as this is backwards-compatible and sane. Original-patch-by: Dan McGee Patch-updated-by: Allan McRae Signed-off-by: Allan McRae --- Here is the link to Dan's original patch from 2012! https://code.toofishes.net/cgit/dan/pacman.git/commit/?h=multiarch&id=673c7d08c30fc897f534bda24e88e806e27bea2b Getting this patch to apply did not require much effort, so I left Dan as the author. We guess the original patch did not get applied because it got lost due to no-one pushing it for inclusion. doc/pacman.conf.5.asciidoc | 10 +++--- lib/libalpm/alpm.h | 30 ++++++++++++----- lib/libalpm/handle.c | 30 +++++++++++++---- lib/libalpm/handle.h | 2 +- lib/libalpm/trans.c | 21 ++++++++++-- src/pacman/conf.c | 33 ++++++++++++------- src/pacman/conf.h | 4 +-- src/pacman/pacman-conf.c | 4 +-- src/pacman/pacman.c | 2 +- test/pacman/meson.build | 2 ++ test/pacman/tests/multiple-architectires01.py | 14 ++++++++ test/pacman/tests/multiple-architectires02.py | 16 +++++++++ 12 files changed, 127 insertions(+), 41 deletions(-) create mode 100644 test/pacman/tests/multiple-architectires01.py create mode 100644 test/pacman/tests/multiple-architectires02.py diff --git a/doc/pacman.conf.5.asciidoc b/doc/pacman.conf.5.asciidoc index 9bd31916..11ca1e4f 100644 --- a/doc/pacman.conf.5.asciidoc +++ b/doc/pacman.conf.5.asciidoc @@ -113,9 +113,9 @@ Options general configuration options.
