# Testcases in this file do not work with embedded server. The reason for this
|
||||
# is that we use the following commands for synchronization:
|
||||
#
|
||||
# set @show_explain_probe_select_id=1;
|
||||
# SET debug_dbug='d,show_explain_probe_join_exec_start';
|
||||
# send select count(*) from t1 where a < 100000;
|
||||
#
|
||||
# When ran with mysqltest_embedded, this translates into:
|
||||
#
|
||||
# Thread1> DBUG_PUSH("d,show_explain_probe_join_exec_start");
|
||||
# Thread1> create another thread for doing "send ... reap"
|
||||
# Thread2> mysql_parse("select count(*) from t1 where a < 100000");
|
||||
#
|
||||
# That is, "select count(*) ..." is ran in a thread for which DBUG_PUSH(...)
|
||||
# has not been called. As a result, show_explain_probe_join_exec_start does not fire, and
|
||||
# "select count(*) ..." does not wait till its SHOW ANALYZE command, and the
|
||||
# test fails.
