# Tests for the performance schema

# =============
# DOCUMENTATION
# =============

# Verify how connections are counted into various tables:
# - accounts
# - users
# - hosts
#
# The tests are written with the following helpers:
# - include/connection_setup.inc
# - include/connection_load.inc
# - include/connection_cleanup.inc
#
# Helpers are intended to be used as follows.
#
# A Typical test t/connection_xxx.test will consist of:
# --source ../include/connection_setup.inc
# --source ../include/connection_load.inc
# --source ../include/connection_cleanup.inc
# and a t/connection_xxx-master.opt file
#
# Naming conventions for t/connection_xxx.test are as follows:
# t/connection_<account><user><host>
#
# <account> corresponds to different sizing settings for 
# the variable performance-schema-accounts-size
# - (blank): accounts-size sufficient to represent all records
# - 3a: accounts-size set to 3
# - no_a: accounts-size set to 0
#
# <user> corresponds to different sizing settings for 
# the variable performance-schema-users-size
# - (blank): users-size sufficient to represent all records
# - 3u: users-size set to 3
# - no_u: users-size set to 0
#
# <host> corresponds to different sizing settings for 
# the variable performance-schema-hosts-size
# - (blank): hosts-size sufficient to represent all records
# - no_h: hosts-size set to 0
