#ifndef SQL_CONNECT_INCLUDED

Enusure that my_global.h is included first - Added sql/mariadb.h file that should be included first by files in sql directory, if sql_plugin.h is not used (sql_plugin.h adds SHOW variables that must be done before my_global.h is included) - Removed a lot of include my_global.h from include files - Removed include's of some files that my_global.h automatically includes - Removed duplicated include's of my_sys.h - Replaced include my_config.h with my_global.h

MDEV-6150 Speed up connection speed by moving creation of THD to new thread Creating a CONNECT object on client connect and pass this to the working thread which creates the THD. Split LOCK_thread_count to different mutexes Added LOCK_thread_start to syncronize threads Moved most usage of LOCK_thread_count to dedicated functions Use next_thread_id() instead of thread_id++ Other things: - Thread id now starts from 1 instead of 2 - Added cast for thread_id as thread id is now of type my_thread_id - Made THD->host const (To ensure it's not changed) - Removed some DBUG_PRINT() about entering/exiting mutex as these was already logged by mutex code - Fixed that aborted_connects and connection_errors_internal are counted in all cases - Don't take locks for current_linfo when we set it (not needed as it was 0 before)

Reuse THD for new user connections - To ensure that mallocs are marked for the correct THD, even if it's allocated in another thread, I added the thread_id to the THD constructor - Added st_my_thread_var to thr_lock_info_init() to avoid a call to my_thread_var - Moved things from THD::THD() to THD::init() - Moved some things to THD::cleanup() - Added THD::free_connection() and THD::reset_for_reuse() - Added THD to CONNECT::create_thd() - Added THD::thread_dbug_id and st_my_thread_var->dbug_id. These are needed to ensure that we have a constant thread_id used for debugging with a THD, even if it changes thread_id (=connection_id) - Set variables.pseudo_thread_id in constructor. Removed not needed sets.

Bug#11765108 (Bug#58036) client utf32, utf16, ucs2 should be disallowed, they crash server Problem: ucs2 was correctly disallowed in "SET NAMES" only, while mysql_real_connect() and mysql_change_user() still allowed to use ucs2, which made server crash. Fix: disallow ucs2 in mysql_real_connect() and mysql_change_user(). @ sql/set_var.cc Using new function. @ sql/sql_acl.cc - Return error if character set initialization failed - Getting rid of pointer aliasing: Initialize user_name to NULL, to avoid double free(). @ sql/sql_connect.cc - in case of unsupported client character set send error and return true - in case of success return false @ sql/sql_connect.h - changing return type for thd_init_client_charset() to bool, to return errors to the caller @ sql/sql_parse.h - introducing a new function, to reuse in all places where we need to check client character set. @ tests/mysql_client_test.c Adding test

WL#5363: Thread Pool Service Interface In order to allow thread schedulers to be dynamically loaded, it is necessary to make the following changes to the server: - Two new service interfaces - Modifications to InnoDB to inform the thread scheduler of state changes. - Changes to the VIO subsystem for checking if data is available on a socket. - Elimination of remains of the old thread pool implementation. The two new service interfaces introduces are: my_thread_scheduler A service interface to register a thread scheduler. thd_wait A service interface to inform thread scheduler that the thread is about to start waiting. In addition, the patch adds code that: - Add a call to thd_wait for table locks in mysys thd_lock.c by introducing a set function that can be used to set a callback to be used when waiting on a lock and resuming from waiting. - Calling the mysys set function from the server to set the callbacks correctly.
