#Want to skip this test from daily Valgrind execution

# Adding big test option for this test.

# ==== Purpose ====
|
|
#
|
|
# Test that @@GLOBAL.GTID_PURGED is maintained correctly when the server
|
|
# restarts and when logs are purged.
|
|
#
|
|
# @@GLOBAL.GTID_PURGED contains the GTIDs that were in binary logs that
|
|
# have been purged. It is initialized at server start and updated
|
|
# each time logs are purged.
|
|
#
|
|
# Test that GTID_PURGED is:
|
|
# - updated when a log is purged
|
|
# - initialized when the server is started
|
|
# - initialized correctly even when the first binlog begins with a
|
|
# truncated Previous_gtids_log_event
|
|
# - initialized correctly even when the first binlog is truncated
|
|
# before the Previous_gtids_log_event
|
|
#
|
|
# ==== Implementation ====
|
|
#
|
|
# Make three big iterations:
|
|
# - first, the server behaves normally and generates a Gtid_log_event
|
|
# - second, the server generates a binlog that is truncated in the
|
|
# middle of the Gtid_log_event
|
|
# - third, the server generates a binlog that is truncated just before
|
|
# the Gtid_log_event
|
|
#
|
|
# Each big iteration has two phases:
|
|
# - In the first phase, we generate a sequence of binlogs.
|
|
# - In the second phase, we purge the binlogs, one at a time, and
|
|
# verify that GTID_PURGED is updated accordingly.
|
|
#
|
|
# In the first phase, we have three nested loops:
|
|
# - The innermost loop generates a sequence of transactions.
|
|
# - The middle loop executes FLUSH LOGS before and after invoking the
|
|
# innermost loop.
|
|
# - The outermost loop restarts the server after invoking the middle
|
|
# loop.
|
|
