# Use this script to manage Galaxy, Tool Shed Install, and Tool Shed database migrations.
#
# For advanced usage and access to the full scope of command line options provided by
# Alembic, you may use the run_alembic.sh script. However, for regular database management
# tasks, we encourage you to use the manage_db.sh script.
#
# NOTE: If your database is empty, use create_db.sh instead.
#
# Database options: galaxy (default), install, tool_shed
# To pass a galaxy config file, you may use `-c|--config|--config-file your-config-file`
#
# To upgrade or downgrade to some version X:
# sh manage_db.sh [upgrade|downgrade] --version=X [tool_shed|install|galaxy]
#
# You may also skip the version argument when upgrading, in which case the database
# will be upgraded to the latest version.
#
# Example 1: upgrade "galaxy" database to version "abc123" using default config:
# sh manage_db.sh upgrade --version=abc123
#
# Example 2: downgrade "install" database to version "xyz789" passing config file "mygalaxy.yml":
# sh manage_db.sh downgrade --version=xyz789 -c mygalaxy.yml install
#
# Example 3: upgrade "galaxy" database to latest version using default config:
# sh manage_db.sh upgrade
#
# (Note: Tool Shed migrations use the legacy migrations system, so we check the
# last argument (the database) to invoke the appropriate script. Therefore, if
# you don't specify the database (galaxy is used by default) and pass a config
# file, your config file should not be named `tool_shed`.)
