#
# This perl script checks for availability of the Perl modules DBI and
# DBD::mysql using the "current" perl interpreter.
#
# Useful for test environment checking before testing executable perl scripts
# in the MySQL Server distribution.
#
# NOTE: The "shebang" on the first line of this script should always point to
# /usr/bin/perl, so that we can use this script to check whether or not we
# support running perl scripts with such a shebang without specifying the
# perl interpreter on the command line. Such a script is mysqlhotcopy.
#
# When run as "checkDBI_DBD-mysql.pl" the shebang line will be evaluated
# and used. When run as "perl checkDBI_DBD-mysql.pl" the shebang line is
# not used.
#
# NOTE: This script will create a temporary file in MTR's tmp dir.
# If modules are found, a mysql-test statement which sets a special
# variable is written to this file. If one of the modules is not found
# (or cannot be loaded), the file will remain empty.
# A test (or include file) which sources that file can then easily do
# an if-check on the special variable to determine success or failure.
#
# Example:
#
# --let $perlChecker= $MYSQLTEST_VARDIR/std_data/checkDBI_DBD-mysql.pl
# --let $resultFile= $MYSQL_TMP_DIR/dbidbd-mysql.txt
# --chmod 0755 $perlChecker
# --exec $perlChecker
# --source $resultFile
# if (!$dbidbd) {
# --skip Test needs Perl modules DBI and DBD::mysql
# }
#
# The calling script is also responsible for cleaning up after use:
#
# --remove_file $resultFile
#
# Windows notes:
# - shebangs may work differently - call this script with "perl " in front.
#
# See mysql-test/include/have_dbi_dbd-mysql.inc for example use of this script.
# This script should be executable for the user running MTR.
