# A shell script to build and run different versions of ldb to check for
# expected forward and backward compatibility with "current" version. The
# working copy must have no uncommitted changes.
#
# Usage: <SCRIPT> [ref_for_current]
# `ref_for_current` can be a revision, tag, commit or branch name. Default is HEAD.
#
# Return value 0 means all regression tests pass. 1 if not pass.
#
# Environment options:
# SHORT_TEST=1 - Test only the oldest branch for each kind of test. This is
# a good choice for PR validation as it is relatively fast and will find
# most issues.
# USE_SSH=1 - Connect to GitHub with ssh instead of https
