WL#3629 - Replication of Invocation and Invoked Features
This changeset adds replication of events and user-defined functions.
There are several bug reports involved in this change:
BUG#16421, BUG#17857, BUG#20384:
This patch modifies the mysql.events table to permit the addition of
another enum value for the status column. The column now has values
of ('DISABLED','SLAVESIDE_DISABLED','ENABLED'). A status of
SLAVESIDE_DISABLED is set on the slave during replication of events.
This enables users to determine which events werereplicated from the
master and to later enable them if they promote the slave to a master.
The CREATE, ALTER, and DROP statements are binlogged.
A new test was added for replication of events (rpl_events).
BUG#17671:
This patch modifies the code to permit logging of user-defined functions.
Note: this is the CREATE FUNCTION ... SONAME variety. A more friendly error
message to be displayed should a replicated user-defined function not be
found in the loadable library or if the library is missing from the
slave.The CREATE andDROP statements are binlogged. A new test was added
for replication of user-defined functions (rpl_udf).
The patch also adds a new column to the mysql.event table named
'originator' that is used to store the server_id of the server that
the event originated on. This enables users to promote a slave to a
master and later return the promoted slave to a slave and disable the
replicated events.

# Purpose: To test that UDFs are replicated in both row based and #
|
||||
# statement based format. This tests work completed in WL#3629. #
|
||||
# #
|
||||
# This test is designed to exercise two of the three types of UDFs: #
|
||||
# 1) UDFs via loadable libraries, and 2) UDFs with a SQL body. #
