# Source validation pre-commit hook
#
# Adapted from the source validation pre-commit hook used in Peloton.
# (see https://github.com/cmu-db/peloton/blob/master/script/git-hooks/pre-commit)
#
# This script collects all modified files and runs it through our source code
# validation script. The validation script returns 0 on success and 1 on any
# failure. This script can also run the server and controller tests by
# uncommenting lines 26-28 and 31-33, respectively. 
#
# To enable, symlink this file to '.git/hooks/pre-commit' like so:
#   cd $OTTERTUNE_DIR/.git/hooks
#   ln -s ../../script/git-hooks/pre-commit ./pre-commit
