这是linux下运行的mysql软件包,可用于linux 下安装 php + mysql + apach 的网络配置

# This test doesn't work with the embedded version as this code
# assumes that one query is running while we are doing queries on
# a second connection.
# This would work if mysqltest run would be threaded and handle each
# connection in a separate thread.

--source include/not_embedded.inc
# PS causes different statistics
