Subject: buildhistory: Allow the version backwards check to be disabled
Date: Sun, 03 Mar 2013 13:07:18 -0000
From: Richard Purdie <richard.purdie@linuxfoundation.org>
X-Patchwork-Id: 45449
Message-Id: <1362316038.4325.4.camel@ted>
To: openembedded-core <openembedded-core@lists.openembedded.org>
Cc: "Eggleton, Paul" <paul.eggleton@intel.com>

When the PR service is not enabled, the versions can go backwards and there
are cases we don't want to know about this. This patch adds a variable
allowing these checks to be turned off whilst still using buildhistory.
