The memory loss could happen in Aria with encrypted tables when Aria failed to encrypt a block.
In normal usage this should never happen.

create_partition_index_description() had wrong logic to calculate
length of the key value buffer that is used by the range optimizer.

For some reason it used MAX(partitioning_columns_len,
subpartitioning_columns_len) while it should use SUM of these values.

- Legacy code would set JOIN_TAB::limit only for EXPLAIN queries (this
  variable is only used when producing EXPLAIN output)

- ANALYZE/SHOW EXPLAIN need to produce EXPLAIN output for non-EXPLAIN
  queries, too, so we should always set JOIN_TAB::limit.

The check for UCONTEXT in cmake was somehow become broken, disabling the
fallback to ucontext. This caused the non-blocking client API to not be
available for non-x86 platforms, on which no hand-crafted assembler
implementation of my_context is available.

DBUG_ASSERT() added in the patch for MDEV-9181 did not take into account
special circumstances for the prepared statement EXECUTE. Fixig the assert.
Also, extending and fixing comments made during MDEV-9181.

The test restarts the server, it should not be executed for embedded

Don't assert if decrypt or encrypt fails if my_assert_on_error is not set.
Added failed file name if encryption/decryption fails.

Wrapping args[0] and args[2] into an Item_cache for aggregate functions.

        The SQL command 'PREPARE' was broken - should be take into
        account.

        Keep the embedded-server version valid.

        SHOW CREATE PROCEDURE/FUNCTION fixed.

        SHOW BINARY LOGS fixed.

        SHOW MASTER STATUS fixed.

        SHOW SLAVE STATUS fixed.

        Fix for SHOW GRANTS statement.

  Fix for SHOW CREATE DATABASE.

operating systems.

The plugin gets the sid of the client process and considers the user
authenticated if the given username matches the username of this sid.

Problem was that insert-order (enforced by the optimizer) did not handle
the case where the bitmap changed to a new one.

Fixed by remembering the last bitmap page used and to force usage of this when inserting new rows

Account for timeout of select returning a 0 error code.

        The metadata creation part of the mysqld_shww_create separated
        to be used on the mysqld_stmt_prepare stage.

  Change parser so it saves all the query line to the ';' in the

Removing the "conv_charset" member and using collation.collation
instead, as they duplicated each other.
