+# Purpose:
+#   This test ensures that, during mysqld initialization, the mysql handle
+# manager starts before the binlog background thread. This is because the
+# binlog background thread uses the mysql handle manager, and if the background
+# thread tries to submit a job to the handle manager before it is
+# initialized/started, mysqld can crash (the actual behavior is undefined).
+# This race condition lead to the problem described in MDEV-26473.
+#
+# Methodology:
+#   This test ensures that the binlog background thread cannot be started
+# before the mysql manager is started. Specifically, it forces a path in
+# the binlog background thread to call mysql_manager_submit() by reducing
+# --gtid-cleanup-batch-size to be 1 (which submits a job to delete unused rows
+# from the mysql.gtid_slave_pos* tables). With this path forced, the main
+# mysqld thread is suspended just before its handle manager initialization to
+# allow time for the binlog thread to call mysql_manager_submit. The fix
+# associated with this test should enforce that the binlog background thread is
+# not created before the handle manager is initialized.

+#
+# Purpose:
+#   This test validates that data is consistent between a primary and replica
+# in semi-sync mode when the primary is issued `SHUTDOWN WAIT FOR SLAVES`
+# during an active communication. More specifically, the primary should not
+# kill the connection until it is sure a replica has received all binlog
+# data, i.e. once the primary receives the ACK. If a primary is issued a
+# shutdown before receiving an ACK, it should wait until either 1) the ACK is
+# received, or 2) the configured timeout (rpl_semi_sync_master_timeout) is
+# reached.
+#
+# Methodology:
+#   Using a topology consisting of one primary with two replicas, all in
+# semi-sync mode, we use DEBUG_DBUG to simulate an error or delay on the
+# replicas during an active communication while the primary is issued
+# `SHUTDOWN WAIT FOR SLAVES`. We create four test cases to ensure the primary
+# will correctly wait for the communication to finish, and use the semi-sync
+# status variables Rpl_semi_sync_master_yes_tx and Rpl_semi_sync_master_no_tx
+# to ensure the connection was not prematurely killed due to the shutdown.
+#   Test Case 1) If both replicas simulate a delay that is within the allowed
+#                timeout, the primary should delay killing the suspended thread
+#                until an ACK is received (Rpl_semi_sync_master_yes_tx should
+#                be 1).
+#   Test Case 2) If both replicas simulate an error before sending an ACK, the
+#                primary should delay killing the suspended thread until the
+#                the timeout is reached (Rpl_semi_sync_master_no_tx should be
+#                1).
+#   Test Case 3) If one replica simulates a delay within the allowed timeout
+#                and the other simulates an error before sending an ACK, the
+#                primary should delay killing the suspended thread until it
+#                receives an ACK from the delayed slave
+#                (Rpl_semi_sync_master_yes_tx should be 1).
+#   Test Case 4) If a replica errors before sending an ACK, it will cause the
+#                IO thread to stop and handle the error. During error handling,
+#                if semi-sync is active, the replica will form a new connection
+#                with the primary to kill the active connection. However, if
+#                the primary is shutting down, it may kill the new connection,
+#                thereby leaving the active semi-sync connection in-tact. The
+#                slave should notice this, and not issue a `QUIT` command to
+#                the primary, which would otherwise be sent to kill an active
+#                connection. This test case validates that the slave does not
+#                send a `QUIT` in this case (Rpl_semi_sync_master_yes_tx should
+#                be 1 because server_3 will send the ACK within a valid
+#                timeout).
+#

+#   MDEV-11853: semisync thread can be killed after sync binlog but before ACK
+#               in the sync state

+  Reconsider logging format in case of INSERT...ON DUPLICATE KEY UPDATE

+
+  Unsafe means that a master could execute the statement differently than
+  the slave.
+  This could can happen in the following cases:
+  - The unique check are done in different order on master or slave
+    (different engine or different key order).
+  - There is a conflict on another key than the first and before the
+    statement is committed, another connection commits a row that conflicts
+    on an earlier unique key. Example follows:
+
+    Below a and b are unique keys, the table has a row (1,1,0)
+    connection 1:
+    INSERT INTO t1 set a=2,b=1,c=0 ON DUPLICATE KEY UPDATE c=1;
+    connection 2:
+    INSERT INTO t1 set a=2,b=2,c=0;
+
+    If 2 commits after 1 has been executed but before 1 has committed
+    (and are thus put before the other in the binary log), one will
+    get different data on the slave:
+    (1,1,1),(2,2,1) instead of (1,1,1),(2,2,0)

+first record of the right_block when a record is about to be inserted
+at the start of the right_block, even though it should "naturally" be
+inserted as the last record of the left_block according to the
+current node pointer in the parent page.
+
+That is, we assume that the lowest common ancestor of the left_block
+and right_block routes the key of the new record to the left_block,
+but a heuristic which tries to avoid overflowing left_block has chosen
+to insert the record into right_block instead. Said ancestor performs
+this routing by comparing the key of the record to a "split point" -
+all records greater or equal to than the split point (node pointer)
+are in right_block, and smaller ones in left_block.
+The split point may be smaller than the smallest key in right_block.
+
+The gap between the last record on the left_block and the first record
+on the right_block is represented as a gap lock attached to the supremum
+pseudo-record of left_block, and a gap lock attached to the new first
+record of right_block.
+
+Thus, inserting the new record, and subsequently adjusting the node
+pointers in parent pages to values smaller or equal to the new
+records' key, will mean that gap will be sliced at a different place
+("moved to the left"): fragment of the 1st gap will now become treated
+as 2nd. Therefore, we must copy any GRANTED locks from 1st gap to the
+2nd gap. Any WAITING locks must be of INSERT_INTENTION type (as no
+other GAP locks ever wait for anything) and can stay at 1st gap, as
+their only purpose is to notify the requester they can retry
+insertion, and there's no correctness requirement to avoid waking them
+up too soon.
