# 2. Some subtests
# - create a new time zone
# - run some statements
# - delete the new time zone.
# But the time zone name used gets somewhere cached and it cannot be
# "reused" later in the same or another session for a new time zone.
# Experiments (2008-11 MySQL 5.1) showed that none of the available
# RESET/FLUSH commands removes these entries.
# 2008-11 MySQL 5.1 Bug#39979 main.events_time_zone does not clean up
# second bad effect
# Therefore we compute unique and unusual timezone names to minimize
# the likelihood that a later test uses the same name.
#
# 3. The subtests mentioned in 2. cause that the AUTO_INCREMENT value
# within "SHOW CREATE TABLE mysql.timezone" differ from the initial one.
# (Bug#39979 main.events_time_zone does not clean up)
# Therefore we reset this value after each of these subtests.
#
# Note(mleich):
# There is a significant likelihood that future improvements of the server
# cause that the solutions for the issues mentioned in 2. and 3. will no
# more work.
# A mysql-test-run.pl feature which allows to enforce
# 1. Server shutdown (-> Problem mentioned in 2. disappears)
# 2. Reset all data to initial state (-> Problem mentioned in 3. disappears)
# 3. Server start
# after a tests would be a perfect replacement.
