From 259d9c501472315e539701f00095743390eb89e5 Mon Sep 17 00:00:00 2001 From: Ryan Harper Date: Thu, 16 Jan 2020 11:29:59 -0600 Subject: Ensure util.get_architecture() runs only once (#172) * Ensure util.get_architecture() runs only once util.get_architecture() recently was wrapped using python3's lru_cache() which will cache the result so we only invoke 'dpkg --print-architecture' once. In practice, cloud-init.log will show multiple invocations of the command. The source of this was that the debian Distro object implements the get_primary_arch() with this command, but it was not calling it from util, but issuing a util.subp() directly. This branch also updates cc_apt_configure methods to fetch the arch value from the distro class, and then ensure that the methods apt_configure calls pass the arch value around. * utils: remove lsb_release and get_architecture wrappers The original lsb_release wrapper was used to prevent polluting the single value we cached, however lru_cache() already handles this case by using args, kwargs values to cache different calls to the method. * rename_apt_list: use all positional parameters --- cloudinit/distros/debian.py | 3 +-- 1 file changed, 1 insertion(+), 2 deletions(-) (limited to 'cloudinit/distros') diff --git a/cloudinit/distros/debian.py b/cloudinit/distros/debian.py index cf082c73..79268371 100644 --- a/cloudinit/distros/debian.py +++ b/cloudinit/distros/debian.py @@ -205,8 +205,7 @@ class Distro(distros.Distro): ["update"], freq=PER_INSTANCE) def get_primary_arch(self): - (arch, _err) = util.subp(['dpkg', '--print-architecture']) - return str(arch).strip() + return util.get_architecture() def _get_wrapper_prefix(cmd, mode): -- cgit v1.2.3
