Marko Mäkelä 0381921e26 MDEV-33277 In-place upgrade causes invalid AUTO_INCREMENT values 
MDEV-33308 CHECK TABLE is modifying .frm file even if --read-only

As noted in commit d0ef1aaf61,
MySQL as well as older versions of MariaDB server would during
ALTER TABLE ... IMPORT TABLESPACE write bogus values to the
PAGE_MAX_TRX_ID field to pages of the clustered index, instead of
letting that field remain 0.
In commit 8777458a6e this field
was repurposed for PAGE_ROOT_AUTO_INC in the clustered index root page.

To avoid trouble when upgrading from MySQL or older versions of MariaDB,
we will try to detect and correct bogus values of PAGE_ROOT_AUTO_INC
when opening a table for the first time from the SQL layer.

btr_read_autoinc_with_fallback(): Add the parameters to mysql_version,max
to indicate the TABLE_SHARE::mysql_version of the .frm file and the
maximum value allowed for the type of the AUTO_INCREMENT column.
In case the table was originally created in MySQL or an older version of
MariaDB, read also the maximum value of the AUTO_INCREMENT column from
the table and reset the PAGE_ROOT_AUTO_INC if it is above the limit.

dict_table_t::get_index(const dict_col_t &) const: Find an index that
starts with the specified column.

ha_innobase::check_for_upgrade(): Return HA_ADMIN_FAILED if InnoDB
needs upgrading but is in read-only mode. In this way, the call to
update_frm_version() will be skipped.

row_import_autoinc(): Adjust the AUTO_INCREMENT column at the end of
ALTER TABLE...IMPORT TABLESPACE. This refinement was suggested by
Debarun Banerjee.

The changes outside InnoDB were developed by Michael 'Monty' Widenius:

Added print_check_msg() service for easy reporting of check/repair messages
in ENGINE=Aria and ENGINE=InnoDB.
Fixed that CHECK TABLE do not update the .frm file under --read-only.
Added 'handler_flags' to HA_CHECK_OPT as a way for storage engines to
store state from handler::check_for_upgrade().

MariaDB: The open source relational database

MariaDB was designed as a drop-in replacement of MySQL(R) with more features, new storage engines, fewer bugs, and better performance.

MariaDB is brought to you by the MariaDB Foundation and the MariaDB Corporation. Please read the CREDITS file for details about the MariaDB Foundation, and who is developing MariaDB.

MariaDB is developed by many of the original developers of MySQL who now work for the MariaDB Corporation, the MariaDB Foundation and by many people in the community.

MySQL, which is the base of MariaDB, is a product and trademark of Oracle Corporation, Inc. For a list of developers and other contributors, see the Credits appendix. You can also run 'SHOW authors' to get a list of active contributors.

Live QA for beginner contributors

MariaDB has a dedicated time each week when we answer new contributor questions live on Zulip. From 8:00 to 10:00 UTC on Mondays, and 10:00 to 12:00 UTC on Thursdays, anyone can ask any questions they’d like, and a live developer will be available to assist.

New contributors can ask questions any time, but we will provide immediate feedback during that interval.
