Dear Mr Sergei Sorry for a careless mistake I thought prototype is working but it is working only for InnoDB not for MyIsam because if we look at table creation which I send you MariaDB [sachin]> create table tbl(int_key int primary key , blob_key blob unique); Query OK, 0 rows affected (0.03 sec) Here I forgot to add engine =myisam . If we the same table creation for myisam table get created but at the time of insert we get this message ERROR 1030 (HY000): Got error 190 "Incompatible key or row definition between the MariaDB .frm file and the information in the storage engine. You have to dump an" from storage engine MyISAM We are getting this becuase in mi_create for each unique_def it creates one keydef and writes it.And this creates two problem 1. frm keydef algorithm is different from saved kefdef algorithm(always zero) for the time I have solved this problem . 2.Mismatch between keydef's keysegs the reason for this is when mi_create creates keyseg for unique_def it did not keeps the orignal uniquedef's keyseg parameters in mind like language start length which creates problem in check_definition function in ha_myisam.cc.I am currently working on it Once again sorry for this foolish mistake.

MDEV-6058 MySQL Bug #11766693: LOG-SLOW-ADMIN-STATEMENTS AND LOG-SLOW-SLAVE-STATEMENTS NOT DISPLAYED. These parameters were moved from the command line options to the system variables section. Treatment of the opt_log_slow_slave_statements changed to let the dynamic change of the variable.

I suppose you didn't run the full test suite. Otherwise you would've noticed that sysvar_* results were changed.
Also, because we have sysvar_* tests, we no longer create <varname>_basic tests for every new variable, they are no longer useful. Starting from 10.1 you only need to test the functionality of new variables, not their basic properties.

please, NO! If you want to test whether a certain row is present in a certain table you do
SELECT columns FROM table;
