MDEV-23841: Memory leak in innodb_monitor_validate()
innodb_monitor_validate(): Let item_val_str() allocate the memory
in THD, so that it will be available to innodb_monitor_update().
In this way, there is no need to allocate another buffer, and
no problem if the call to innodb_monitor_update() is skipped due
to an invalid value that is passed to another configuration parameter.
There are some other callers to st_mysql_sys_var::val_str()
that validate configuration parameters that are related to FULLTEXT INDEX,
but they will allocate memory by invoking thd_strmake().
Currently include/have_innodb_4k.inc etc. files only check that the
server is running with the corresponding page size. I think it would
be more convenient if they actually enforced the setting.
MDEV-21679 innodb_zip.index_large_prefix_4k fails with ER_TOO_BIG_ROWSIZE
The test innodb_zip.index_large_prefix_4k would not run unless it is
invoked as
./mtr --mysqld=--innodb-page-size=4k innodb_zip.index_large_prefix_4k
This test was originally developed to cover an option that was removed
in commit 0c92794db3026cda03218caf4918b996baab6ba6. Starting with
MariaDB Server 10.2, which introduced innodb_default_row_format=dynamic,
the option innodb_large_prefix had become useless.
Let us remove some of the stale tests and adjust the outcome to the
expected behaviour.
MDEV-21678 innodb_gis.gis_split_nan fails with ER_CANT_CREATE_GEOMETRY_OBJECT
Let us avoid inserting the rows fid=714 and fid=715, because we would
evaluate g=NULL for them, and NULL values are not allowed in InnoDB
SPATIAL INDEX.
Also, let the test run on any page size, and on non-debug builds.
