- FLUSH GLOBAL STATUS now resets most global_status_vars.
At this stage, this is mainly to be used for testing.
- FLUSH SESSION STATUS added as an alias for FLUSH STATUS.
- FLUSH STATUS does not require any privilege (before required RELOAD).
- FLUSH GLOBAL STATUS requires RELOAD privilege.
- All global status reset moved to FLUSH GLOBAL STATUS.
- Replication semisync status variables are now reset by
FLUSH GLOBAL STATUS.
- In test cases, the only changes are:
- Replace FLUSH STATUS with FLUSH GLOBAL STATUS
- Replace FLUSH STATUS with FLUSH STATUS; FLUSH GLOBAL STATUS.
This was only done in a few tests where the test was using SHOW STATUS
for both local and global variables.
- Uptime_since_flush_status is now always provided, independent if
ENABLED_PROFILING is enabled when compiling MariaDB.
- @@global.Uptime_since_flush_status is reset on FLUSH GLOBAL STATUS
and @@session.Uptime_since_flush_status is reset on FLUSH SESSION STATUS.
- When connected, @@session.Uptime_since_flush_status is set to 0.

# How to use this script in a test case
|
|
# =====================================
|
|
#
|
|
# The general table io test template is as follows
|
|
#
|
|
# --source include/not_embedded.inc
|
|
# --source include/have_perfschema.inc
|
|
# --source ../include/table_io_setup_helper.inc
|
|
# ... more setup scripts as needed ...
|
|
# update performance_schema.setup_consumers set enabled='YES';
|
|
# ... test payload here ...
|
|
# ... optionally, add this insert between statements
|
|
# ... to make the final output more readable
|
|
# insert into test.marker set a=1;
|
|
# ... more test payload here ...
|
|
# ... optionaly, add the following line (by default, only "test" is dumped) ...
|
|
# let $schema_to_dump="db1", "db2", "db3";
|
|
# --source ../include/table_io_result_helper.inc
|
|
# Optional: Repeat several times
|
|
# update performance_schema.setup_consumers set enabled='YES';

|

# --source ../include/table_io_result_helper.inc
|
|
# ... cleanup
|
|
# --source ../include/table_io_cleanup_helper.inc
|
|
#
|
|
# (end of template)
