Lock LOCK_plugin only when the variable is a plugin variable.
Lock LOCK_global_system_variables only when the variable is a
global-only variable or a plugin variable.
Also fix lockless session value for Sys_var_multi_source_ulonglong.
This saves 54 calls to pthread_mutex_lock when constructing the
initial OK packet.
The added testcases do not show the lock savings. They are there to
improve coverage for the MDEV-31609 feature, in light of bugs like
MDEV-39207 and MDEV-39217.
Add two new variables:
file_key_management_digest={sha1|sha224|sha256|sha384|sha512}
This specify the digest function to use in key derivation of the key
used for decryption of the keyfile.
file_key_management_use_pbkdf2=N
This specify whether pbkdf2 is used in the key derivation, and if
so (N != 0), how many iterations.
into a separate transaction_participant structure
handlerton inherits it, so handlerton itself doesn't change.
but entities that only need to participate in a transaction,
like binlog or online alter log, use a transaction_participant
and no longer need to pretend to be a full-blown but invisible
storage engine which doesn't support create table.
MDEV-32188 make TIMESTAMP use whole 32-bit unsigned range
This is done by changing my_time_t from long to unsigned long.
The effect of this is that on windows compling old clients may
get warnings of if they compare my_time_t with as signed variable.
Other things
- Removed my_time_t from include/*.pp files as it is different on windows
and linux.
- Changed do_abi_check.cmake to first print abi_check and then the
conflicting file (this makes it easier to find the cause of the error).
- Adding automatic conversion operator from LEX_STRING to LEX_CSTRING
Now a LEX_STRING can be passed directly to any function expecting
a LEX_CSTRING parameter passed by value or by reference.
- Removing a number of duplicate methods accepting LEX_STRING.
Now the code used the LEX_CSTRING version.
This patch ensures that all direct and indirect calls to
encryption_crypt provide a `dlen` value correctly initialized to the
destination buffer length, allowing encryption plugins to verify
available space. It also adds assertions to verify related invariants.

This is used by InnoDB to detect if CREATE...SELECT is used
Other things:
- Changed InnoDB to use thd_ddl_options()
- Removed lock checking code for create...select (Approved by Marko)
- Defining MariaDB_FUNCTION_PLUGIN
- Changing the code in /plugins/type_inet/ and /plugins/type_test/
to use MariaDB_FUNCTION_PLUGIN instead of MariaDB_FUNCTION_COLLECTION_PLUGIN.
- Changing maturity for the INET6 data type plugin from experimental to alpha.
