yaf源碼閱讀之 -- 框架基本生命週期 (yaf.c)

MINIT

php-fpm啓動master時會啓動php擴展，在yaf源碼中，這裏對應的是MINIT及以前的操做，相關源碼位於yaf.c ：

1. 讀取php.ini中的yaf配置
   在PHP_INI_BEGIN()和PHP_INI_END()之間定義相關參數的默認值、做用域、回調函數等

2. 在MINIT中定義YAF常量，如YAF_VERSION等

3. 在MINIT中載入yaf框架各個組件，自此YAF框架就常駐內存，yaf的快的優點也源於此。

RINIT

請求初始化只是對yaf用戶應用級別的配置作了初始化

PHP_RINIT_FUNCTION(yaf)
{
	YAF_G(throw_exception) = 1;
	YAF_G(ext) = zend_string_init(YAF_DEFAULT_EXT, sizeof(YAF_DEFAULT_EXT) - 1, 0);

	YAF_G(default_module) = zend_string_init(
			YAF_ROUTER_DEFAULT_MODULE, sizeof(YAF_ROUTER_DEFAULT_MODULE) - 1, 0);
	YAF_G(default_controller) = zend_string_init(
			YAF_ROUTER_DEFAULT_CONTROLLER, sizeof(YAF_ROUTER_DEFAULT_CONTROLLER) - 1, 0);
	YAF_G(default_action) = zend_string_init(
			YAF_ROUTER_DEFAULT_ACTION, sizeof(YAF_ROUTER_DEFAULT_ACTION) - 1, 0);
	return SUCCESS;
}

RSHUTDOWN

銷燬用戶應用級別的配置

PHP_RSHUTDOWN_FUNCTION(yaf)
{
	YAF_G(running) = 0;
	YAF_G(in_exception)	= 0;
	YAF_G(catch_exception) = 0;

	YAF_G(default_route) = NULL;

{
	UNREGISTER_INI_ENTRIES();

	if (YAF_G(configs)) {
		zend_hash_destroy(YAF_G(configs));
		pefree(YAF_G(configs), 1);
