First step in build avoidance is the creation of a reference build. We need to capture the state of all the git trees that contribute to the reference build. This update will save the git context to $MY_WORKSPACE/CONTEXT The context file format is actually a shell script that can be run to recreate the build context. repo init ... repo sync cd $MY_REPO/.. source .../CONTEXT Sample CONTEXT file .... (cd ./cgcs-root && git checkout -f 12a159594130d75aedf40da3f3b1e6bd7f9ff375) (cd ./cgcs-root/stx/git/calico && git checkout -f 12a159594130d75aedf40da3f3b1e6bd7f9ff375) (cd ./cgcs-root/stx/git/ceilometer && git checkout -f 12a159594130d75aedf40da3f3b1e6bd7f9ff375) ... (cd ./stx-tools && git checkout -f 12a159594130d75aedf40da3f3b1e6bd7f9ff375) (cd ./.repo/manifests && git checkout -f 12a159594130d75aedf40da3f3b1e6bd7f9ff375) (cd ./.repo/repo && git checkout -f 12a159594130d75aedf40da3f3b1e6bd7f9ff375) This update also the git_list function, which populates the previously introduced GIT_LIST variable, and can be used in several other code paths where we want to find all gits in a directory tree.
