#
# Test mysql_plugin tool
#
# This test contains test cases for testing the mysql_plugin client with
# the daemon_example plugin. Test cases include tests for:
#
#   - successful enable/disable
#   - incorrect paths
#   - missing paths/options
#
# Implementation Notes
#
# The mysql_plugin tool now accepts --mysqld the path to mysqld server. The
# mysqld path is extracted from MYSQLD_BOOTSTRAP_CMD line. We also extract
# the path of MYSQLD_BASEDIR (where mysql exists) and use it for the errmsg
# file. The directories differ between Windows and Unix but the Perl script
# included below will pick as per platform.
#
# The test is also designed to issue the --skip directive if the location of
# the mysqld, my_print_defaults, or daemon_example.ini files cannot be found.
#

--source include/not_embedded.inc

# Add the datadir, basedir, plugin_dir to the bootstrap command
let $MYSQLD_DATADIR= `select @@datadir`;
let $MYSQL_BASEDIR= `select @@basedir`;
let $MYSQL_ERRMSG_BASEDIR=`select @@lc_messages_dir`;
let $PLUGIN_DIR=`select @@plugin_dir`;

--disable_abort_on_error

# Perl script to extract the location of the basedir from environment
# variables. This is needed to ensure the test will run on the PB machines
# designed to test release as well as debug builds. It also checks for the
# location of the my_print_defaults and daemon_example.ini files.
