INITIALIZE - Build or acquire a sorted list of variables to use for input. + Use the SHOW_VAR struct as an intermediate format common to system, status + and user vars: + + SHOW_VAR + Name - Text string + Value - Pointer to memory location, function, subarray structure + Type - Scalar, function, or subarray + Scope - SESSION, GLOBAL, BOTH + + Steps: + - Register the server's internal buffer with the class. Acquire locks + if necessary, then scan the contents of the input buffer. + - For system variables, convert each element to SHOW_VAR format, store in + a temporary array. + - For status variables, copy existing global status array into a local + array that can be used without locks. Expand nested subarrays, indicated + by a type of SHOW_ARRAY. + + 2. MATERIALIZE - Convert the list of SHOW_VAR variables to string format, + store in a local cache: + - Resolve each variable according to the type. + - Recursively process unexpanded nested arrays and callback functions. + - Aggregate values across threads for global status. + - Convert numeric values to a string. + - Prefix variable name with the plugin name. + + 3. OUTPUT - Iterate the cache for the SHOW command or table query. + + CLASS OVERVIEW + -------------- + 1. System_variable - A materialized system variable + 2. Status_variable - A materialized status variable + 3. PFS_variable_cache - Base class that defines the interface for the operations above. + public + init_show_var_array() - Build SHOW_VAR list of variables for processing + materialize_global() - Materialize global variables, aggregate across sessions + materialize_session() - Materialize variables for a given PFS_thread or THD + materialize_user() - Materialize variables for a user, aggregate across related threads. + materialize_host() - Materialize variables for a host, aggregate across related threads. + materialize_account() - Materialize variables for a account, aggregate across related threads. + private + m_show_var_array - Prealloc_array of SHOW_VARs for input to Materialize + m_cache - Prealloc_array of materialized variables for output + do_materialize_global() - Implementation of materialize_global() + do_materialize_session() - Implementation of materialize_session() + do_materialize_client() - Implementation of materialize_user/host/account() + + 4. PFS_system_variable_cache - System variable implementation of PFS_variable_cache + 5. PFS_status_variable_cache - Status variable implementation of PFS_variable_cache + 6. Find_THD_variable - Used by the thread manager to find and lock a THD. + + GLOSSARY + -------- + Status variable - Server or plugin status counter. Not dynamic. + System variable - Server or plugin configuration variable. Usually dynamic. + GLOBAL scope - Associated with the server, no context at thread level. + SESSION scope - Associated with a connection or thread, but no global context. + BOTH scope - Globally defined but applies at the session level. + Initialize - Build list of variables in SHOW_VAR format. + Materialize - Convert variables in SHOW_VAR list to string, cache for output. + Manifest - Substep of Materialize. Resolve variable values according to + type. This includes SHOW_FUNC types which are resolved by + executing a callback function (possibly recursively), and + SHOW_ARRAY types that expand into nested subarrays. + LOCK PRIORITIES + --------------- + System Variables + LOCK_plugin_delete (block plugin delete) + LOCK_system_variables_hash + LOCK_thd_data (block THD delete) + LOCK_thd_sysvar (block system variable updates, alloc_and_copy_thd_dynamic_variables) + LOCK_global_system_variables (very briefly held) + + Status Variables + LOCK_status + LOCK_thd_data (block THD delete) +*/ + +/* Iteration on THD from the sql layer. */ +//#include "mysqld_thd_manager.h" +#define PFS_VAR +/* Class sys_var */ +#include "set_var.h" +/* convert_value_to_string */ +#include "sql_show.h" +/* PFS_thread */ +#include "pfs_instr.h" +#include "pfs_user.h" +#include "pfs_host.h" +#include "pfs_account.h" +#include "my_thread.h" + +/* Global array of all server and plugin-defined status variables. */ +extern DYNAMIC_ARRAY all_status_vars; +extern bool status_vars_inited; +static const uint SYSVAR_MEMROOT_BLOCK_SIZE = 4096; + +extern mysql_mutex_t LOCK_plugin_delete; + +class Find_THD_Impl; +class Find_THD_variable; +typedef PFS_connection_slice PFS_client; + +/** + CLASS System_variable - System variable derived from sys_var object. +*/ +class System_variable +{ +public: + System_variable(); + System_variable(THD *target_thd, const SHOW_VAR *show_var, + enum_var_type query_scope, bool ignore); + ~System_variable() {} + + bool is_null() const { return !m_initialized; } + bool is_ignored() const { return m_ignore; } + +public: + const char *m_name; + size_t m_name_length; + char m_value_str[SHOW_VAR_FUNC_BUFF_SIZE+1]; + size_t m_value_length; + enum_mysql_show_type m_type; + int m_scope; + bool m_ignore; + const CHARSET_INFO *m_charset; + +private: + bool m_initialized; + void init(THD *thd, const SHOW_VAR *show_var, enum_var_type query_scope); +}; + + +/** + CLASS Status_variable - Status variable derived from SHOW_VAR. +*/ +class Status_variable +{ +public: + Status_variable() : m_name(NULL), m_name_length(0), m_value_length(0), + m_type(SHOW_UNDEF), + m_charset(NULL), m_initialized(false) {} + + Status_variable(const SHOW_VAR *show_var, STATUS_VAR *status_array, enum_var_type query_scope); + + ~Status_variable() {} + + bool is_null() const {return !m_initialized;}; + +public: + const char *m_name; + size_t m_name_length; + char m_value_str[SHOW_VAR_FUNC_BUFF_SIZE+1]; + size_t m_value_length; + SHOW_TYPE m_type; + const CHARSET_INFO *m_charset; +private: + bool m_initialized; + void init(const SHOW_VAR *show_var, STATUS_VAR *status_array, enum_var_type query_scope); +}; + + +/** + CLASS Find_THD_variable - Get and lock a validated THD from the thread manager. +*/ +class Find_THD_variable //: public Find_THD_Impl +{ +public: + Find_THD_variable() : m_unsafe_thd(NULL) {} + Find_THD_variable(THD *unsafe_thd) : m_unsafe_thd(unsafe_thd) {} + + virtual bool operator()(THD *thd) + { + //TODO: filter bg threads?
