Description: mysql_upgrade fails with below error,
when there are duplicate entries(like 'root'@'LOCALHOST'
and 'root'@'localhost') in mysql.user table.
ERROR 1062 (23000) at line 1140: Duplicate entry 'localhost-root' for key 'PRIMARY'
FATAL ERROR: Upgrade failed
Analysis: As part of the bug 12917151 fix we are
making all the hostnames as lower case hostnames.
So, this has been done by mysql_upgrade.
In case of above mentioned duplicate entries
mysql_upgrade tries to change hostname to lowercase.
Since there is already 'root'@'localhost' exists.
it is failing with "duplicate entry" error.
Fix: Since its a valid error failure. We are
making the error more verbose. So, that user will
delete the duplicate errors manually.
Along with existing error we are printing below
error as well.
ERROR 1644 (45000) at line 1153: Multiple accounts exist for @user_name, @host_name that differ only in Host lettercase; remove all except one of them
10.0 variation of the problem was that system tables were altered
during mysql_upgrade process using old (smaller) column lengths.
At the end the tables were altered again, so the structure was restored,
but if there were long values before the upgrade, they were truncated.
Fixed by using correct column length in alter statements.
mysql_upgrade overrode some of the custom changes made to system tables
in order to increase user name length.
Make ALTER statements involving the affected columns take into account
length changes, as per https://mariadb.com/kb/en/create-user/#user-names
Analysis: In earlier MySQL 5.6 versions this table innodb_index_stats used to have a foreign key referencing to innodb_table_stats. However, in newer MySQL 5.6 versions this foreign key is removed and if you upgrade, your innodb_table_stats is created by the earlier mariadb version, thus a newer version will complain that the table is incorrectly defined.
Added drop foreign key on mysql_system_tables_fix.sql to be executed on mysql_upgrade.
UPPER CASE HOST NAME ANYMORE
Description:
It is not possible to drop users with host names with upper case
letters in them. i.e DROP USER 'root'@'Tmp_Host_Name'; is failing
with error.
Analysis: Since the fix 11748570 we came up with lower case hostnames
as standard. But in the current bug the hostname is created by
mysql_install_db script is still having upper case hostnames.
So, if we have the hostname with upper case letters like(Tmp_Host_Name)
then we will have as it is stored in the mysql.user table.
In this case if use "'DROP USER 'root'@'Tmp_Host_Name';" it gives
error because we do compare with the lower case of hostname since the
11748570 fix.
Fix: We need to convert the hostname to lower case before storing into
the mysql.user table when we run the mysql_install_db script.

and small collateral changes
mysql-test/lib/My/Test.pm:
somehow with "print" we get truncated writes sometimes
mysql-test/suite/perfschema/r/digest_table_full.result:
md5 hashes of statement digests differ, because yacc token codes are different in mariadb

mysql-test/suite/perfschema/r/information_schema.result:

mysql-test/suite/perfschema/r/nesting.result:
this differs, because we don't rewrite general log queries, and multi-statement
packets are logged as a one entry. this result file is identical to what mysql-5.6.5
produces with the --log-raw option.
mysql-test/suite/perfschema/r/relaylog.result:
MariaDB modifies the binlog index file directly, while MySQL 5.6 has a feature "crash-safe binlog index" and modifies a special "crash-safe" shadow copy of the index file and then moves it over. That's why this test shows "NONE" index file writes in MySQL and "MANY" in MariaDB.
mysql-test/suite/perfschema/r/server_init.result:
MariaDB initializes the "manager" resources from the "manager" thread, and starts this thread only when --flush-time is not 0. MySQL 5.6 initializes "manager" resources unconditionally on server startup.
mysql-test/suite/perfschema/r/stage_mdl_global.result:
this differs, because MariaDB disables query cache when query_cache_size=0. MySQL does not
do that, and this causes useless mutex locks and waits.

One can set @@global.max_user_connections to -1 to block anyone, except SUPER user, to login.
If max_user_connection is 0, one can't change it without a restart (needed to get user connections counting to work correctly)

Made max_user_connections signed.

Added max_user_connections_checking so that we know if max_user_connections was 0 at startup
(Which means that we will not do connection counting for accounts that don't have user resource limits)
Set thd->start_utime at same time as thr_create_utime. (Before start_utime could be < thr_create_utime which lead to wrong query counting)

Bug #11936829: DIFF. BETWEEN MYSQL.USER (AUTHENTICATION_STRING) IN
FRESH AND UPGRADED 5.5.11
There was no modification for pre 5.5.11 builds that had
authentication_string. Thus the column was not upgraded
by mysql_upgrade.
Fixed by adding an ALTER TABLE MODIFY to update an existing
column to the latest type version.
Test suite added.
configuration wizard to fail
Made the fields mysql.user.plugin and mysql.user.authentication_string
nullable to conform with some older clients doing inserts instead of
using the commands.
This patch corrects the problem by fixing the definition and alterations
of the mysql.user table in the .sql files.
Also included are new result files for tests that examine the name
column of the mysql.user table.
