We should assume that the store engine will report the first duplicate key for this case.
Old code of suppression of unsafe logging error with LIMIT didn't work, because of wrong usage of my_interval_timer().
Suppress unsafe logging errors to the error log if we get too many unsafe logging errors in a short time.
This is to not overflow the error log with meaningless errors.
- Each error code is suppressed and counted separately.
- We do a 5 minute suppression of new errors if we get more than 10 errors in that time.
Only print unsafe logging errors if log_warnings > 1.

- adjusted a test result according to the change made for MDEV-6100;
- added explicit timezone for engines/iuds, since MTR in
MariaDB does not set it like MySQL's, and tests with constant TIMESTAMP
can have different outcome
- Character set code & tests from Alexander Barkov
- Integration with ALTER TABLE, REPAIR and open_table from Monty
The problem was that MySQL 5.6 added some croatian and vitanamese character set collations that are incompatible with MariaDB.
The fix is to move the MariaDB conflicting collation numbers out of the region that MySQL is likely to use.
mysql_upgrade, REPAIR TABLE or ALTER TABLE will fix the collations.
If one tries to access and old incompatible table, one will get the error "Table upgrade required...."
After this patch, MariaDB supports all the MySQL character set collations and the old MariaDB croatian collations, which are closer to the latest standard than the MySQL versions.
New character sets:
ucs2_croatian_mysql561_uca_ci
utf8_croatian_mysql561_uca_ci
utf16_croatian_mysql561_uca_ci
utf32_croatian_mysql561_uca_ci
utf8mb4_croatian_mysql561_uca_ci

Testing of upgrading tables with old collations
The test ensures that:
- We will get an error if we try to open a table with old collations.
- CHECK TABLE will detect that the table needs to be upgraded.
- ALTER TABLE and REPAIR will fix the table.
- mysql_upgrade works as expected

mysys/charset-def.c:
Added new character sets
mysys/charset.c:
Always give an error, if requested, if a character set didn't exist
sql/handler.cc:
- Added upgrade_collation() to check if collation is compatible with old version
- check_collation_compatibility() checks if we are using an old collation from MariaDB 5.5 or MySQL 5.6
- ha_check_for_upgrade() returns HA_ADMIN_NEEDS_ALTER if we have an incompatible collation
sql/handler.h:
Added new prototypes
sql/sql_table.cc:
- Mark that tables are opened for ALTER TABLE
- If table needs to be upgraded, ensure we are not using online alter table.
sql/table.cc:
- If we are using an old incompatible collation, change to use the new one and mark table as incompatible.
- Give an error if we try to open an incompatible table.
sql/table.h:
Added error that table needs to be rebuild
storage/connect/ha_connect.cc:
Fixed compiler warning
strings/ctype-uca.c:
New character sets
- as of 5.5.27, YEAR(2) is deprecated, hence the new warning;
- MDEV-553 - different error code/message on out-of-range autoincrement;
- INSERT IGNORE now produces a warning if a duplicate was encountered (change pushed along with MDEV-553)
=== Problem ===
The test is dependent on binlog positions and checks
to see if the command 'START SLAVE' functions correctly
with the 'UNTIL' clause added to it. The 'UNTIL' clause
is added to specify that the slave should start and run
until the SQL thread reaches a given point in the master
binary log or in the slave relay log.
The test uses hard coded values for MASTER_LOG_POS and
RELAY_LOG_POS, instead of extracting it using
query_get_value() function. There is a test
'rpl.rpl_row_until' which does the similar thing but uses
query_get_value() function to set the values of
MASTER_LOG_POS/ RELAY_LOG_POS. To be precise,
rpl.rpl_row_until is a modified version of
engines/func.rpl_row_until.test.
The use of hard coded values may lead the slave to stop at a position
which may differ from the expected position in the binlog file,
an example being the failure of engines/funcs.rpl_row_until in
mysql-5.1 given as:
"query 'select * from t2' failed. Table 'test.t2' doesn't exist".
In this case, the slave actually ran a couple of extra commands
as a result of which the slave first deleted the table and then
ran a select query on table, leading to the above mentioned failure.
=== Fix ===
1) Fixed the code for failure seen in rpl.rpl_row_until.
This test was also failing although the symptoms of
failure were different.
2) Copied the contents from rpl.rpl_row_until into
into engines/funcs.rpl.rpl_row_until.
3) Updated engines/funcs.rpl_row_until.result accordingly.
mysql-test/suite/engines/funcs/r/rpl_row_until.result:
modified to accomodate the changes in corresponding
test file.
mysql-test/suite/engines/funcs/t/disabled.def:
removed from the list of disabled tests.
mysql-test/suite/engines/funcs/t/rpl_row_until.test:
fixed rpl.rpl_row_until and copied its content to
engines/funcs.rpl_row_until. The reason being both
are same tests but rpl.rpl_row_until is an
updated version.
mysql-test/suite/rpl/t/disabled.def:
removed from the list of disabled tests.
sql/sql_repl.cc:
Added a check to catch an improper combination
of arguements passed to 'START SLAVE UNTIL'. Earlier,
START SLAVE UNTIL MASTER_LOG_FILE='master-bin.000001',
MASTER_LOG_POS=561, RELAY_LOG_POS=12;
passed. It is now detected and an error is reported.
Following reasons caused mismatches:
- different handling of invalid values;
- different CAST results with fractional seconds;
- microseconds support in MariaDB;
- different algorithm of comparing temporal values;
- differences in error and warning texts and codes;
- different approach to truncating datetime values to time;
- additional collations;
- different record order for queries without ORDER BY;
- MySQL bug#66034.
