Warning added.

Fix reinitialize vers_write on table reopen.

Make all accesses to btr_cur_n_non_sea atomic.

fix is simple: just move mp->file under mp->global protection

MDEV-18350 Using audit plugin with MySQL, mysqld crashes when running COM_INIT_DB against invalid database.

mysql_event_general structure changed in 10.3.
the database_length should be size_t now instead of the int.

Turn off versioned_write for DELETE HISTORY.

* Made make_versioned_*() proxies inline;
* Renamed truncate_history to delete_history

Part of:
MDEV-19814 Server crash in row_upd_del_mark_clust_rec or Assertion
`update->n_fields < ulint(table->n_cols + table->n_v_cols)' failed in
upd_node_t::make_versioned_helper

This removes the test combination
rocksdb_rpl.mdev12179 'innodb,row,row-write-committed-slave-gtid-optimized'
for which the server failed to start due to the invalid parameter
slave_gtid_info=optimized.

This was broken in 5173e396

fts_sync(): Remove the constant parameter has_dict=false.

fts_sync_table(): Remove the constant parameter has_dict=false,
and the redundant parameter unlock_cache = !wait.
Make wait=true the default parameter.

PROBLEM
-------

Index defined on a virtual column whose base column was in a fk
relation was not getting updated. This is because while getting
the updated field information from the update vector of the parent
table we were comparing the column number of the base column (for
virtual column) in child table with the associated column number
in the parent table. There was a mismatch in this column number
because of which this update field information was skipped and
subsequently index was not getting updated.

FIX

Fixing post push test issues.

Recorded the result files for following:
rpl_stm_drop_create_temp_table.result
rpl_mixed_drop_create_temp_table.result.

The function pointer ut_timer() was only used by the
InnoDB defragmenting thread. Let InnoDB use a single monotonic
high-precision timer, my_interval_timer() [in nanoseconds],
occasionally wrapped by microsecond_interval_timer().

srv_defragment_interval: Change from "timer" units to nanoseconds.

This concludes the InnoDB time function cleanup that was
motivated by MDEV-14154. Only ut_time_ms() will remain for now,
wrapping my_interval_timer().

MDEV-5589 commit set up a policy to skip DROP TEMPORARY TABLE binary logging
in case the target table has not been "CREATEed" in binlog (no CREATE
Query-log-event was logged into the binary log).

It turns out that

1. the rule did not cover non-existing table DROPped with IF-EXISTS clause.
   The logged-create knowledge for the non-existing one does not even need
   MDEV-5589 patch, and

2. connection close disobeys it to trigger automatic DROP-IF-EXISTS
   binlogging.

Either 1 or 2 or even both is/are also responsible for unexpected binlog
records observed in MDEV-17863, actually rendering a referred
@@global.read_only irrelevant as far as the described stored procedure
definition *and* the ROW binlog-format are concerned.
