# ==== Purpose ====
|
|
#
|
|
# Kill a query in the master connection, and then try to reap the
|
|
# result of the killed query.
|
|
#
|
|
# ==== Usage ====
|
|
#
|
|
# The following variables should be set before sourcing this file.
|
|
#
|
|
# $debug_lock: name of the debug user lock, if set, will release/lock
|
|
# the specified debug lock accordingly, and before
|
|
# sourcing this, connection 'master' should get the user
|
|
# lock and run a query in another thread, which will
|
|
# block before creating statement event.
|
|
#
|
|
# $connection_name: name of the connection that is waiting for the
|
|
# lock, this can not be 'master'
|
|
#
|
|
# $connection_id: id of the connection that is waiting for the lock
|
|
#
|
|
# Example:
|
|
# let $debug_lock=;
|
|
# connection master1;
|
|
# let $connection_name= master1;
|
|
# let $connection_id= `SELECT CONNECTION_ID()`;
|
|
# send CREATE TABLE t1;
|
|
# source kill_query.inc;
|
|
#
|
|
# let $debug_lock= "debug_lock.before_query_log_event";
|
|
# connection master;
|
|
# eval SELECT GET_LOCK($debug_lock, 10);
|
|
# connection master1;
|
|
# let $connection_name= master1;
|
|
# let $connection_id= `SELECT CONNECTION_ID()`;
|
|
# send CREATE TABLE t1;
|
|
# source kill_query.inc;
|

|
|

|
|
}
|
|
|
|
# reap the result of the waiting query
