For this exercise, we assume that the issued statement is a simple SELECT * FROM some_table WHERE field_x = 200, where some_table is a MyISAM table. This is important, because, as you ll see, the MyISAM storage engine will actually execute the code for the request through the storage engine abstraction layer. We ll begin our journey at the starting point of the MySQL server, in the main() routine of /sql/mysqld.cc, as shown in Listing 4-8. Listing 4-8. /sql/mysqld.cc main() int main(int argc, char **argv) { init_common_variables(MYSQL_CONFIG_NAME, argc, argv, load_default_groups); init_ssl(); server_init(); init_server_components(); start_signal_handler(); // Creates pidfile acl_init((THD *)0, opt_noacl); init_slave(); create_shutdown_thread(); create_maintenance_thread(); handle_connections_sockets(0); DBUG_PRINT("quit",("Exiting main thread")); exit(0); } This is where the main server process execution begins. We ve highlighted some of the more interesting sections. init_common_variables() works with the command-line arguments used on executing mysqld or mysqld_safe, along with the MySQL configuration files. We ve gone over some of what init_server_components() and acl_init() do in this chapter. Basically, init_server_components() makes sure the MYSQL_LOG objects are online and working, and acl_init() gets the access control system up and running, including getting the privilege cache into memory. When we discussed the thread and resource management subsystem, we mentioned that a separate thread is created to handle maintenance tasks and also to handle shutdown events. create_maintenance_thread() and create_shutdown_thread() accomplish getting these threads up and running. The handle_connections_sockets() function is where things start to really get going. Remember from our discussion of the thread and resource management subsystem that a thread is created for each incoming connection request, and that a separate thread is in charge of monitoring those connection threads 15 Well, this is where it happens.

13 Aug 2018 ... Discover how to enable QR code generation for TOTP authenticator apps that work with ASP . NET Core two-factor authentication. If you want to work with an accelerometer in the Windows Phone 7 emulator, there is an obvious problem: the emulator has no access to an accelerometer so always returns a vector containing the values (0, 0, -1) This makes it very hard to test your game unless on a real device There have been various clever workarounds for this problem suggested on the Internet (including hooking a Nintendo Wii controller up to the PC and using its accelerometer), but they involve a fairly considerable amount of effort to get working We can take advantage of a couple of much simpler options: use the touch screen to simulate accelerometer data or use the keyboard to simulate rotation of the device Either way, we want to ensure that this happens only when running on the emulator, not on a real device. how to generate qr code in asp net core How To Generate QR Code Using ASP .

13 Aug 2018 ... Discover how to enable QR code generation for TOTP authenticator apps that work with ASP . NET Core two-factor authentication. Listing 4-9. /sql/mysqld.cc handle_connections_sockets() handle_connections_sockets(arg attribute((unused))) { if (ip_sock != INVALID_SOCKET) { FD_SET(ip_sock,&clientFDs); DBUG_PRINT("general",("Waiting for connections.")); while (!abort_loop) { new_sock = accept(sock, my_reinterpret_cast(struct sockaddr *) (&cAddr), &length); thd= new THD; if (sock == unix_sock) thd->host=(char*) my_localhost; create_new_thread(thd); } } } The basic idea is that the mysql.sock socket is tapped for listening, and listening begins on the socket. While the listening is occurring on the port, if a connection request is received, a new THD struct is created and passed to the create_new_thread() function. The if (sock==unix_sock) checks to see if the socket is a Unix socket. If so, it defaults the THD->host member variable to be localhost. Let s check out what create_new_thread() does, in Listing 4-10. Listing 4-10. /sql/mysqld.cc create_new_thread() static void create_new_thread(THD *thd) { DBUG_ENTER("create_new_thread"); /* don't allow too many connections */ if (thread_count - delayed_insert_threads >= max_connections+1 || abort_loop) { DBUG_PRINT("error",("Too many connections")); close_connection(thd, ER_CON_COUNT_ERROR, 1); delete thd; DBUG_VOID_RETURN; } pthread_mutex_lock(&LOCK_thread_count); if (cached_thread_count > wake_thread) { start_cached_thread(thd); } else { Microsoft has provided a way to determine whether we are running in the emulator, and it can be accessed by adding a reference to the MicrosoftPhone DLL Once this has been added, we can query the MicrosoftDevicesEnvironmentDeviceType property, which will return either Device or Emulator as appropriate Having determined that we are running in the emulator, we can now apply either of the two accelerometer simulation methods described The first of these, using the touch screen, is shown in Listing 4 28 It calculates the position of the touch point across the width and height of the screen and uses this position to derive a value for the AccelerometerData vector It sets just the x and y axis values, leaving the z value set permanently at 0 Listing 4 28 Simulating the accelerometer using touch screen input void AccelerometerReadingChanged(object sender, AccelerometerReadingEventArgs e) { if (MicrosoftDevices. // in the CellsGrid constructor /* Allow baseTG to be read and changed at runtime (so it can be rotated). */ baseTG = new TransformGroup(); baseTG.setCapability(TransformGroup.ALLOW_TRANSFORM_READ); baseTG.setCapability(TransformGroup.ALLOW_TRANSFORM_WRITE); // initialize the grid with Cell objects cells = new Cell[GRID_LEN][GRID_LEN][GRID_LEN]; for (int i=0; i < GRID_LEN; i++) for (int j=0; j < GRID_LEN; j++) for (int k=0; k < GRID_LEN; k++) { cells[i][j][k] = new Cell(i-GRID_LEN/2, j-GRID_LEN/2, k-GRID_LEN/2); // subtract GRID_LEN/2 so grid is centered baseTG.addChild( cells[i][j][k].getTG() ); //connect to baseTG } The runtime manipulation of scene graph nodes is only possible if those nodes have the desired capabilities switched on with setCapability() calls. The orientation of the baseTG TransformGroup will be read and changed at runtime, necessitating two setCapability() calls. Each cell is managed by a Cell object that is passed a coordinate derived from its position in the cells[][][] array. The subtraction of GRID_LEN/2 from i, j, and k means that the 10-by-10-by-10 grid is centered on the origin. To understand this, it helps to recall how the viewer is orientated with respect to the axes (see Figure 2-12). how to generate qr code in asp net core codebude/QRCoder: A pure C# Open Source QR Code ... - GitHub
