Marko Mäkelä 51fb39bf17 MDEV-19586: Restore pointer indirection for recv_t::data
Something was wrong with the removal of pointer indirection,
because on 32-bit Windows we got crash recovery failures.
Curiously, WITH_ASAN of a 32-bit debug build did not notice anything.

This reverts a part of commit b7fc2c899e.

We have a 2MiB recv_sys.buf for the initial buffering. The minimum size
of log_sys.buf would be 16MiB, and that buffer should be practically
unused during recovery. If the buffer pool size is measured in gigabytes,
it would indeed make sense to use the buffer pool for the recovered log
records, perhaps after we have run out of log_sys.buf.

FIXME: allow the entire buf_block_t::frame to be used for buffered
log records, and remove MEM_HEAP_FOR_RECV_SYS. For example, use
buf_page_t::list or buf_page_t::LRU for keeping track of memory that
was allocated for recovery? Most members of buf_block_t
(except buf_block_t::frame) are unused when
block->page.state == BUF_BLOCK_MEMORY.

MariaDB: drop-in replacement for MySQL

MariaDB is 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.

A description of the MariaDB project and a manual can be found at:

https://mariadb.com/kb/en/mariadb-versus-mysql-compatibility/

https://mariadb.com/kb/en/library/new-and-old-releases/

https://mariadb.org/

As MariaDB is a full replacement of MySQL, the MySQL manual at http://dev.mysql.com/doc is generally applicable.

Help

More help is available from the Maria Discuss mailing list https://launchpad.net/~maria-discuss and the #maria IRC channel on Freenode.

Live QA for beginner contributors

MariaDB has a dedicated time each week when we answer new contributor questions live on Zulip and IRC. From 8:00 to 10:00 UTC on Mondays, and 10:00 to 12:00 UTC on Thursdays, anyone can ask any questions theyd 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.
