Function protectClient

app/redis-6.2.6/src/networking.c:1698–1704

This function is used when we want to re-enter the event loop but there * is the risk that the client we are dealing with will be freed in some * way. This happens for instance in: * * * DEBUG RELOAD and similar. * * When a Lua script is in -BUSY state. * * So the function will protect the client by doing two things: * * 1) It removes the file events. This way it is not possible that an

 * 2) Moreover it makes sure that if the client is freed in a different code
 *    path, it is not really released, but only marked for later release. */
