* Windows related cleanups, remove old code.Vladislav Vaintroub2019-06-181-25/+0
| | | | | | | | | - Do not scan registry to check if TCPIP is supported. - Do not read registry under HKEY_LOCAL_MACHINE\SOFTWARE\MySQL anymore. - Do not load threadpool function dynamically, it is available since Win7. - simplify win32_init_tcp_ip(), and return error of WSAStartup() fails. - Correct comment in my_parameter_handler()

| | | | * | MDEV-13179 main.errors fails with wrong errnoMonty2017-08-071-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The problem was that the introduction of max-thread-mem-used can cause an allocation error very early, even before mysql_parse() is called. As mysql_parse() calls thd->reset_for_next_command(), which called clear_error(), the error number was lost. Fixed by adding an option to have unique messages for each KILL signal and change max-thread-mem-used to use this new feature. This removes a lot of problems with the original approach, where one could get errors signaled silenty almost any time. ixed by moving clear_error() from reset_for_next_command() to do_command(), before any memory allocation for the thread. Related changes: - reset_for_next_command() now have an optional parameter if we should call clear_error() or not. By default it's called, but not anymore from dispatch_command() which was the original problem. - Added optional paramater to clear_error() to force calling of reset_diagnostics_area(). Before clear_error() only called reset_diagnostics_area() if there was no error, so we normally called reset_diagnostics_area() twice. - This change removed several duplicated calls to clear_error() when starting a query. - Reset max_mem_used on COM_QUIT, to protect against kill during quit. - Use fatal_error() instead of setting is_fatal_error (cleanup) - Set fatal_error if max_thead_mem_used is signaled. (Same logic we use for other places where we are out of resources)

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Remove threads that are doing nothing but wait - main thread now handles the connections (if threadpool is used, also threadpool threads would wait for connections) - thread for socket and pipe connections are removed - shutdown thread is now removed, we wait for shutdown notification in main thread as well - kill_server() is also called inside the main thread, after connection loop finished.

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)

* MDEV-246 - Aborted_clients incremented during ordinary connection closeVladislav Vaintroub2012-05-031-0/+4
| | | | | | The problem was increment of aborted_threads variable due to thd->killed which was set when threadpool connection was terminated . The fix is not to set thd->killed anymore, there is no real reason for doing it.. Added a test that checks that status variable aborted_clients does not grow for ordinary disconnects, and that successful KILL increments this variable.
