When adding new privilege bits, don't forget to update:

- Add a new LAST_version_ACL
- Add a new ALL_KNOWN_ACL_version
- Change ALL_KNOWN_ACL to ALL_KNOWN_ACL_version
- Change GLOBAL_ACLS, DB_ACLS, TABLE_ACLS, PROC_ACLS if needed
- Change SUPER_ADDED_SINCE_USER_TABLE_ACL if needed
In other files:
- static struct show_privileges_st sys_privileges[]
- static const char *command_array[] and static uint command_lengths[]
- mariadb_system_tables.sql and mariadb_system_tables_fix.sql
- acl_init() or whatever - to define behaviour for old privilege tables
- Update User_table_json::get_access()
- sql_yacc.yy - for GRANT/REVOKE to work
Important: the enum should contain only single-bit values.

MDEV-31273: Precompute binlog checksums Compute binlog checksums (when enabled) already when writing events into the statement or transaction caches, where before it was done when the caches are copied to the real binlog file. This moves the checksum computation outside of holding LOCK_log, improving scalabitily. At stmt/trx cache write time, the final end_log_pos values are not known, so with this patch these will be set to 0. Events that are written directly to the binlog file (not through stmt/trx cache) keep the correct end_log_pos value. The GTID and COMMIT/XID events at the start and end of event groups are written directly, so the zero end_log_pos is only for events in the middle of event groups, which do not negatively affect replication. An option --binlog-legacy-event-pos, off by default, is provided to disable this behavior to provide backwards compatibility with any external applications that might rely on end_log_pos in events in the middle of event groups. Checksums cannot be pre-computed when binlog encryption is enabled, as encryption relies on correct end_log_pos to provide part of the nonce/IV. Checksum pre-computation is also disabled for WSREP/Galera, as it uses events differently in its write-sets and so on. Extending pre-computation of checksums to Galera where it makes sense could be added in a future patch. The current --binlog-checksum configuration is saved in binlog_cache_data at transaction start and used to pre-compute checksums in cache, if applicable. When the cache is later copied to the binlog, a check is made if the saved value still matches the configured global value; if so, the events are block-copied directly into the binlog file. If --binlog-checksum was changed during the transaction, events are re-written to the binlog file one-by-one and the checksums recomputed/discarded as appropriate.

MDEV-4991: GTID binlog indexing Improve the performance of slave connect using B+-Tree indexes on each binlog file. The index allows fast lookup of a GTID position to the corresponding offset in the binlog file, as well as lookup of a position to find the corresponding GTID position. This eliminates a costly sequential scan of the starting binlog file to find the GTID starting position when a slave connects. This is especially costly if the binlog file is not cached in memory (IO cost), or if it is encrypted or a lot of slaves connect simultaneously (CPU cost). The size of the index files is generally less than 1% of the binlog data, so not expected to be an issue. Most of the work writing the index is done as a background task, in the binlog background thread. This minimises the performance impact on transaction commit. A simple global mutex is used to protect index reads and (background) index writes; this is fine as slave connect is a relatively infrequent operation. Here are the user-visible options and status variables. The feature is on by default and is expected to need no tuning or configuration for most users. binlog_gtid_index On by default. Can be used to disable the indexes for testing purposes. binlog_gtid_index_page_size (default 4096) Page size to use for the binlog GTID index. This is the size of the nodes in the B+-tree used internally in the index. A very small page-size (64 is the minimum) will be less efficient, but can be used to stress the BTree-code during testing. binlog_gtid_index_span_min (default 65536) Control sparseness of the binlog GTID index. If set to N, at most one index record will be added for every N bytes of binlog file written. This can be used to reduce the number of records in the index, at the cost only of having to scan a few more events in the binlog file before finding the target position Two status variables are available to monitor the use of the GTID indexes: Binlog_gtid_index_hit Binlog_gtid_index_miss The "hit" status increments for each successful lookup in a GTID index. The "miss" increments when a lookup is not possible. This indicates that the index file is missing (eg. binlog written by old server version without GTID index support), or corrupt.

This is for audit / secure configuration check purposes. Create new MTR tests to make sure that the newly created global variables can be visible from the command line interface. Behavior before the code change: MariaDB [(none)]> SHOW GLOBAL VARIABLES WHERE -> Variable_name LIKE 'binlog_do_db' OR -> Variable_name LIKE 'binlog_ignore_db' OR -> Variable_name LIKE 'binlog_row_event_max_size'; Empty set (0.001 sec) Behavior after the code change: MariaDB [(none)]> SHOW GLOBAL VARIABLES WHERE -> Variable_name LIKE 'binlog_do_db' OR -> Variable_name LIKE 'binlog_ignore_db' OR -> Variable_name LIKE 'binlog_row_event_max_size'; +---------------------------+-------+ | Variable_name | Value | +---------------------------+-------+ | binlog_do_db | | | binlog_ignore_db | | | binlog_row_event_max_size | 8192 | +---------------------------+-------+ 3 rows in set (0.001 sec) Note: For `binlog_do_db` and `binlog_ignore_db`, we add a new class `Sys_var_binlog_filter` to handle the dynamically-composable command line options for `binlog_do_db` and `binlog_ignore_db`. Below is the motivation: When the users start the server with the option --binlog-do-db="database1" --binlog-do-db="database2" The expected behavior is that the system should allow replication for both `database1` and `database2`, which is the logic of the original code. However, when turning the variables into system variables, the functionality does not exist any more, since system variables will only handle the last occurrence of the option, and in this case, the system will only be able to handle `database2`.
