usage_description = "
Runs all of the scripts given as arguments against multiple MySQL versions using docker
Uses mysqld.sh to boot a mysql docker environment and pipe source statements in to the container
Sources each script in MySQL in the order given
Runs against a list of MySQL versions from the first of the following conditions:
- If \$ MYSQL_VERSIONS environment variable is set, then only tests against those versions in the order given, space or comma separated, with 'x' used as a wildcard ( eg. '5.x , 8.x' )
- If \$ GET_DOCKER_TAGS is set and dockerhub_show_tags.py is found in the \$ PATH ( from DevOps Python tools repo) , then uses it to fetch the latest live list of version tags available from the dockerhub API, reordering by newest first
- Falls back to the following pre-set list of versions, reordering by newest first:
$( tr ' ' '\n' <<< " $mysql_versions " )
If a script has a headers such as:
-- Requires MySQL N.N
-- Requires MySQL >= N.N
-- Requires MySQL < N.N
then will only run that script on the specified versions of MySL
This is for convenience so you can test a whole repository such as my SQL-scripts repo just by doing: ${ 0 ##*/ } mysql_*.sql
and have this code figure out the combinations of scripts to run vs versions
