# ==== Purpose ====
#
# Check that anonymous ownership is acquired and released as expected.
#
# When a client sets GTID_NEXT='ANONYMOUS', it 'acquires anonymous
# ownership'. Then, when it commits or rolls back, it 'releases
# anonymous ownership. If GTID_NEXT='AUTOMATIC' and GTID_MODE=OFF or
# OFF_PERMISSIVE, then a client 'acquires anonymous ownership' when
# the transaction is flushed to the binary log, and releases it on
# commit. If a client already has GTID_NEXT='ANONYMOUS' but anonymous
# ownership has been released by a commit or rollback, then anonymous
# ownership is re-acquired when the next statement begins to execute.
# As an exception, "innocent" statements do not re-acquire anonymous
# ownership; here "innocent" statements include SET, SHOW, SELECT, and
# DO statements that do not invoke stored functions.
#
# Multiple clients can 'hold anonymous ownership' at the same time.
# The global status variable ONGOING_ANONYMOUS_TRANSACTION_COUNT
# contains the number of clients that 'hold anonymous ownership'. The
# session variable @@session.gtid_owned contains the string
# 'ANONYMOUS' if the client hold anonymous ownership.
#
# This test checks different ways to acquire and release ownership,
# and verifies that ONGOING_ANONYMOUS_TRANSACTION_COUNT and
# @@SESSION.GTID_OWNED change accordingly.
#
# ==== Implementation ====
#
# We test a number of statements. For each statement we specify what
# is the expected values of GTID_NEXT, GTID_OWNED, and
# ONGOING_ANONYMOUS_TRANSACTION_COUNT after the statement. Each
# statement is stored together with the expected values of these
# variables in one row of the table 'statements'. Thus the test
# scenarios are specified by the contents of this table in the
# 'Initialize' section below. In the 'Test' section, we execute one
# row at a time from the table and check that the variables change as
# specified.

#
# WL#7083: GTIDs: set gtid_mode=ON online
# - Behavior of anonymous ownership was specified in this worklog.
# - Most of test was implemented in this worklog.

# WL#7592: GTIDs: generate Gtid_log_event and Previous_gtids_log_event always
# BUG#20341210: WL7592: ASSERT AT BINLOG.CC:1139 FOR IMPLICIT COMMIT WHEN GTID_NEXT=ANONYMOUS
# - The bugfix was verified by the test case
# binlog_gtid_next_anonymous_implicit_commit.test, which was
# subsequently moved into the present test (the cases for implicit
# commit inside a transaction).
# Test sets gtid_mode explicitly, no need to run in multiple combinations.
