There was an incorrect check for MariaDB and InnoDB
tables fields count. Corruption was reported when there was no corruption.
Also, a warning message had incorrect field numbers for both MariaDB and InnoDB
tables.
ha_innobase::open(): fixed check and message
Background: Used encryption key_id is stored to encryption metadata
i.e. crypt_data that is stored on page 0 of the tablespace of the
table. crypt_data is created only if implicit encryption/not encryption
is requested i.e. ENCRYPTED=[YES|NO] table option is used
fil_create_new_single_table_tablespace on fil0fil.cc.
Later if encryption is enabled all tables that use default encryption
mode (i.e. no encryption table option is set) are encrypted with
default encryption key_id that is 1. See fil_crypt_start_encrypting_space on
fil0crypt.cc.
ha_innobase::check_table_options()
If default encryption is used and encryption is disabled, you may
not use nondefault encryption_key_id as it is not stored anywhere.
The relevant InnoDB/XtraDB fixes up to 5.6.42 had already
been applied to MariaDB in commit 30c3d6db32.
Revert some changes that appeared in
the merge commit 87d852f102.
- Backported the MYSQL_SYSVAR_SIZE_T to 10.0
- The parameter innodb_ft_result_cache_limit was only 32 bits wide
also on 64-bit systems. Make it size_t, so that it will be 64 bits
on 64-bit systems.
- Added a test case that show how innodb_ft_result_cache_limit variables
behaves in 32bit and 64 bit system.
wsrep_append_foreign_key() and wsrep_append_key() used to take a boolean
argument denoting whether the relevant certification key type is shared
(assuming it is exclusive if the argument is false). Change that
argument to the enum wsrep_key_type from wsrep_api.h, so that eventually
other types can also be passed (like WSREP_KEY_SEMI).
This is a non-functional change.
(cherry picked from commit 360bf36dbb9378b36ef57921c725a9505e19e0d9)
Disable "Invalid (old?) table or database name" warning when
converting table names in InnoDB's get_foreign_key_info().
Because a name can be a temporary table name during the ALTER TABLE,
and some other thread can do SHOW CREATE TABLE for the other table
in the FK relationships _anytime_.
If we have a 2+ node cluster which is replicating from an async master
and the binlog_format is set to STATEMENT and multi-row inserts are executed
on a table with an auto_increment column such that values are automatically
generated by MySQL, then the server node generates wrong auto_increment
values, which are different from what was generated on the async master.
The causes and fixes:
1. We need to improve processing of changing the auto-increment values
after changing the cluster size.
2. If wsrep auto_increment_control switched on during operation of
the node, then we should immediately update the auto_increment_increment
and auto_increment_offset global variables, without waiting of the next
invocation of the wsrep_view_handler_cb() callback. In the current version
these variables retain its initial values if wsrep_auto_increment_control
is switched on during operation of the node, which leads to inconsistent
results on the different nodes in some scenarios.
3. If wsrep auto_increment_control switched off during operation of the node,
then we must return the original values of the auto_increment_increment and
auto_increment_offset global variables, as the user has set. To make this
possible, we need to add a "shadow copies" of these variables (which stores
the latest values set by the user).
Problem:
As part of bug #24938374 fix, dict_operation_lock was not taken by
fts_optimize_thread while syncing fts cache.
Due to this change, alter query is able to update SYS_TABLE rows
simultaneously. Now when fts_optimizer_thread goes open index table,
It doesn't open index table if the record corresponding to that table is
set to REC_INFO_DELETED_FLAG in SYS_TABLES and hits an assert.
Fix:
If fts sync is already in progress, Alter query would wait for sync to
complete before renaming table.

ha_innobase::optimize(): If both innodb_defragment and
innodb_optimize_fulltext_only are at their default settings (OFF),
fall back to ALTER TABLE. Else process one or both options.
ha_innobase::set_partition_owner_stats(): Remove (unused function).
ha_innobase::ha_partition_stats: Remove (the variable is never read).
Remove unused ut_timer functions.
