From 36100edc77e8245b080343e12f59c26e35d66f2e Mon Sep 17 00:00:00 2001 From: Jonathan Maw Date: Thu, 29 Nov 2012 16:13:48 +0000 Subject: Avoid rebuilds when unimportant morphology contents change This changes the cache key generation so that it will ignore unimportant fields of the morphology, e.g. description, build-depends, chunks. description is unimportant because it does not affect building, and build-depends/chunks are unimportant because they are already considered --- ...hology-contents-do-not-change-cache-keys.script | 41 ++++++++++++++++++++++ 1 file changed, 41 insertions(+) create mode 100755 tests.as-root/unimportant-morphology-contents-do-not-change-cache-keys.script (limited to 'tests.as-root') diff --git a/tests.as-root/unimportant-morphology-contents-do-not-change-cache-keys.script b/tests.as-root/unimportant-morphology-contents-do-not-change-cache-keys.script new file mode 100755 index 00000000..27adf8c6 --- /dev/null +++ b/tests.as-root/unimportant-morphology-contents-do-not-change-cache-keys.script @@ -0,0 +1,41 @@ +#!/bin/bash +# +# Copyright (C) 2012 Codethink Limited +# +# This program is free software; you can redistribute it and/or modify +# it under the terms of the GNU General Public License as published by +# the Free Software Foundation; version 2 of the License. +# +# This program is distributed in the hope that it will be useful, +# but WITHOUT ANY WARRANTY; without even the implied warranty of +# MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
