There are no new keywords, no new statements. + This guarantees that existing applications will run the same way with or + without the performance schema. + + All the instrumentation points return "void", there are no error codes. + Even if the performance schema internally fails, execution of the server + code will proceed. + + None of the instrumentation points allocate memory. + All the memory used by the performance schema is pre-allocated at startup, + and is considered "static" during the server life time. + + None of the instrumentation points use any pthread_mutex, pthread_rwlock, + or pthread_cond (or platform equivalents). + Executing the instrumentation point should not cause thread scheduling to + change in the server. + + In other words, the implementation of the instrumentation points, + including all the code called by the instrumentation points, is: + - malloc free + - mutex free + - rwlock free + + TODO: All the code located in storage/perfschema is malloc free, + but unfortunately the usage of LF_HASH introduces some memory allocation. + This should be revised if possible, to use a lock-free, + malloc-free hash code table. + + @subsection PRINCIPLE_PERFORMANCE No performance hit + + The instrumentation of the server should be as fast as possible. + In cases when there are choices between: + - doing some processing when recording the performance data + in the instrumentation, + - doing some processing when retrieving the performance data, + + priority is given in the design to make the instrumentation faster, + pushing some complexity to data retrieval. + + As a result, some parts of the design, related to: + - the setup code path, + - the query code path, + + might appear to be sub-optimal. + + The criterion used here is to optimize primarily the critical path (data + collection), possibly at the expense of non-critical code paths. + + @subsection PRINCIPLE_NOT_INTRUSIVE Unintrusive instrumentation + + For the performance schema in general to be successful, the barrier + of entry for a developer should be low, so it's easy to instrument code. + + In particular, the instrumentation interface: + - is available for C and C++ code (so it's a C interface), + - does not require parameters that the calling code can't easily provide, + - supports partial instrumentation (for example, instrumenting mutexes does + not require that every mutex is instrumented) + + @subsection PRINCIPLE_EXTENDABLE Extendable instrumentation + + As the content of the performance schema improves, + with more tables exposed and more data collected, + the instrumentation interface will also be augmented + to support instrumenting new concepts. + Existing instrumentations should not be affected when additional + instrumentation is made available, and making a new instrumentation + available should not require existing instrumented code to support it. + + @subsection PRINCIPLE_VERSIONED Versioned instrumentation + + Given that the instrumentation offered by the performance schema will + be augmented with time, when more features are implemented, + the interface itself should be versioned, to keep compatibility + with previous instrumented code. + + For example, after both plugin-A and plugin-B have been instrumented for + mutexes, read write locks and conditions, using the instrumentation + interface, we can anticipate that the instrumentation interface + is expanded to support file based operations. + + Plugin-A, a file based storage engine, will most likely use the expanded + interface and instrument its file usage, using the version 2 + interface, while Plugin-B, a network based storage engine, will not change + its code and not release a new binary. + + When later the instrumentation interface is expanded to support network + based operations (which will define interface version 3), the Plugin-B code + can then be changed to make use of it. + + Note, this is just an example to illustrate the design concept here. + Both mutexes and file instrumentation are already available + since version 1 of the instrumentation interface. + + @subsection PRINCIPLE_DEPLOYMENT Easy deployment + + Internally, we might want every plugin implementation to upgrade the + instrumented code to the latest available, but this will cause additional + work and this is not practical if the code change is monolithic. + + Externally, for third party plugin implementors, asking implementors to + always stay aligned to the latest instrumentation and make new releases, + even when the change does not provide new functionality for them, + is a bad idea. + + For example, requiring a network based engine to re-release because the + instrumentation interface changed for file based operations, will create + too many deployment issues. + + So, the performance schema implementation must support concurrently, + in the same deployment, multiple versions of the instrumentation + interface, and ensure binary compatibility with each version. + + In addition to this, the performance schema can be included or excluded + from the server binary, using build time configuration options. + + Regardless, the following types of deployment are valid: + -

a raw ABI (Application Binary Interface) layer, that exposes the primitive + instrumentation functions exported by the performance schema instrumentation + - an API (Application Programing Interface) layer, + that provides many helpers for a developer instrumenting some code, + to make the instrumentation as easy as possible. + + The ABI layer consists of: +@code +#include "mysql/psi/psi.h" +@endcode + + The API layer consists of: +@code +#include "mysql/psi/mutex_mutex.h" +#include "mysql/psi/mutex_file.h" +@endcode + + The first helper is for mutexes, rwlocks and conditions, + the second for file io. + + The API layer exposes C macros and typedefs which will expand: + - either to non-instrumented code, when compiled without the performance + schema instrumentation + - or to instrumented code, that will issue the raw calls to the ABI layer + so that the implementation can collect data. + + Note that all the names introduced (for example, @c mysql_mutex_lock) do not + collide with any other namespace. + In particular, the macro @c mysql_mutex_lock is on purpose not named + @c pthread_mutex_lock. + This is to: + - avoid overloading @c pthread_mutex_lock with yet another macro, + which is dangerous as it can affect user code and pollute + the end-user namespace. + - allow the developer instrumenting code to selectively instrument + some code but not all. + + @section PRINCIPLES Design principles + + The ABI part is designed as a facade, that exposes basic primitives. + The expectation is that each primitive will be very stable over time, + but the list will constantly grow when more instruments are supported. + To support binary compatibility with plugins compiled with a different + version of the instrumentation, the ABI itself is versioned + (see @c PSI_v1, @c PSI_v2). + + For a given instrumentation point in the API, the basic coding pattern + used is: + -

computed on the fly, + - computed on demand, based on other available data. + + 'EVENTS_WAITS_HISTORY_INFINITE' is a table that does not exist, + the best approximation is EVENTS_WAITS_HISTORY_LONG. + Aggregates computed on the fly in fact are based on EVENTS_WAITS_CURRENT, + while aggregates computed on demand are based on other + EVENTS_WAITS_SUMMARY_BY_xxx tables. + + To better understand the implementation itself, a bit of math is + required first, to understand the model behind the code: + the code is deceptively simple, the real complexity resides + in the flyweight of pointers between various performance schema buffers. + + @section DIMENSION Concept of dimension + + An event measured by the instrumentation has many attributes. + An event is represented as a data point P(x1, x2, ..., xN), + where each x_i coordinate represents a given attribute value. + + Examples of attributes are: + - the time waited + - the object waited on + - the instrument waited on + - the thread that waited + - the operation performed + - per object or per operation additional attributes, such as spins, + number of bytes, etc. + + Computing an aggregate per thread is fundamentally different from + computing an aggregate by instrument, so the "_BY_THREAD" and + "_BY_EVENT_NAME" aggregates are different dimensions, + operating on different x_i and x_j coordinates. + These aggregates are "orthogonal". + + @section PROJECTION Concept of projection + + A given x_i attribute value can convey either just one basic information, + such as a number of bytes, or can convey implied information, + such as an object fully qualified name. + + For example, from the value "test.t1", the name of the object schema + "test" can be separated from the object name "t1", so that now aggregates + by object schema can be implemented. + + In math terms, that corresponds to defining a function: + F_i (x): x --> y + Applying this function to our point P gives another point P': + + F_i (P): + P(x1, x2, ..., x{i-1}, x_i, x{i+1}, ..., x_N) + --> P' (x1, x2, ..., x{i-1}, f_i(x_i), x{i+1}, ..., x_N) + + That function defines in fact an aggregate ! + In SQL terms, this aggregate would look like the following table: + +@verbatim + CREATE VIEW EVENTS_WAITS_SUMMARY_BY_Func_i AS + SELECT col_1, col_2, ..., col_{i-1}, + Func_i(col_i), + COUNT(col_i), + MIN(col_i), AVG(col_i), MAX(col_i), -- if col_i is a numeric value + col_{i+1}, ..., col_N + FROM EVENTS_WAITS_HISTORY_INFINITE + group by col_1, col_2, ..., col_{i-1}, col{i+1}, ..., col_N. +@endverbatim + + Note that not all columns have to be included, + in particular some columns that are dependent on the x_i column should + be removed, so that in practice, MySQL's aggregation method tends to + remove many attributes at each aggregation steps. + + For example, when aggregating wait events by object instances, + - the wait_time and number_of_bytes can be summed, + and sum(wait_time) now becomes an object instance attribute. + - the source, timer_start, timer_end columns are not in the + _BY_INSTANCE table, because these attributes are only + meaningful for a wait. + + @section COMPOSITION Concept of composition + + Now, the "test.t1" --> "test" example was purely theory, + just to explain the concept, and does not lead very far. + Let's look at a more interesting example of data that can be derived + from the row event. + + An event creates a transient object, PFS_wait_locker, per operation. + This object's life cycle is extremely short: it's created just + before the start_wait() instrumentation call, and is destroyed in + the end_wait() call. + + The wait locker itself contains a pointer to the object instance + waited on. + That allows to implement a wait_locker --> object instance projection, + with m_target. + The object instance life cycle depends on _init and _destroy calls + from the code, such as mysql_mutex_init() + and mysql_mutex_destroy() for a mutex. + + The object instance waited on contains a pointer to the object class, + which is represented by the instrument name. + That allows to implement an object instance --> object class projection. + The object class life cycle is permanent, as instruments are loaded in + the server and never removed. + + The object class is named in such a way + (for example, "wait/sync/mutex/sql/LOCK_open", + "wait/io/file/maria/data_file) that the component ("sql", "maria") + that it belongs to can be inferred. + That allows to implement an object class --> server component projection. + + Back to math again, we have, for example for mutexes: + + F1 (l) : PFS_wait_locker l --> PFS_mutex m = l->m_target.m_mutex + + F1_to_2 (m) : PFS_mutex m --> PFS_mutex_class i = m->m_class + + F2_to_3 (i) : PFS_mutex_class i --> const char *component = + substring(i->m_name, ...) + + Per components aggregates are not implemented, this is just an illustration. + + F1 alone defines this aggregate: + + EVENTS_WAITS_HISTORY_INFINITE --> EVENTS_WAITS_SUMMARY_BY_INSTANCE + (or MUTEX_INSTANCE) + + F1_to_2 alone could define this aggregate: + + EVENTS_WAITS_SUMMARY_BY_INSTANCE --> EVENTS_WAITS_SUMMARY_BY_EVENT_NAME + + Alternatively, using function composition, with + F2 = F1_to_2 o F1, F2 defines: + + EVENTS_WAITS_HISTORY_INFINITE --> EVENTS_WAITS_SUMMARY_BY_EVENT_NAME + + Likewise, F_2_to_3 defines: + + EVENTS_WAITS_SUMMARY_BY_EVENT_NAME --> EVENTS_WAITS_SUMMARY_BY_COMPONENT + + and F3 = F_2_to_3 o F_1_to_2 o F1 defines: + + EVENTS_WAITS_HISTORY_INFINITE --> EVENTS_WAITS_SUMMARY_BY_COMPONENT + + What has all this to do with the code ? + + Functions (or aggregates) such as F_3 are not implemented as is. + Instead, they are decomposed into F_2_to_3 o F_1_to_2 o F1, + and each intermediate aggregate is stored into an internal buffer. + This allows to support every F1, F2, F3 aggregates from shared + internal buffers, where computation already performed to compute F2 + is reused when computing F3. + + @section OBJECT_GRAPH Object graph + + In terms of object instances, or records, pointers between + different buffers define an object instance graph. + + For example, assuming the following scenario: + -

events that occur during the instrumented code execution are noted with numbers, + as in [1]. Code executed by these events has an impact on overhead. + - events that occur during TRUNCATE TABLE operations are noted with numbers, + followed by "-RESET", as in [4-RESET]. + Code executed by these events has no impact on overhead, + since they are executed by independent monitoring sessions. + - events that occur when a reader extracts data from a performance schema table + are noted with letters, as in [A]. The name of the table involved, + and the method that builds a row are documented. Code executed by these events + has no impact on the instrumentation overhead. Note that the table + implementation may pull data from different buffers. + - nominal code paths are in plain lines. A "nominal" code path corresponds to + cases where the performance schema buffers are sized so that no records are lost. + - degenerated code paths are in dotted lines. A "degenerated" code path corresponds + to edge cases where parent buffers are full, which forces the code to aggregate to + grand parents directly. + + Implemented as: + - [1] @c start_mutex_wait_v1(), @c end_mutex_wait_v1() + - [2] @c destroy_mutex_v1() + - [3] @c aggregate_thread_waits() + - [4] @c PFS_account::aggregate_waits() + - [A] EVENTS_WAITS_SUMMARY_BY_THREAD_BY_EVENT_NAME, + @c table_ews_by_thread_by_event_name::make_row() + - [B] EVENTS_WAITS_SUMMARY_BY_INSTANCE, + @c table_events_waits_summary_by_instance::make_mutex_row() + - [C] EVENTS_WAITS_SUMMARY_GLOBAL_BY_EVENT_NAME, + @c table_ews_global_by_event_name::make_mutex_row() + - [D] EVENTS_WAITS_SUMMARY_BY_ACCOUNT_BY_EVENT_NAME, + @c table_ews_by_account_by_event_name::make_row() + - [E] EVENTS_WAITS_SUMMARY_BY_USER_BY_EVENT_NAME, + @c table_ews_by_user_by_event_name::make_row() + - [F] EVENTS_WAITS_SUMMARY_BY_HOST_BY_EVENT_NAME, + @c table_ews_by_host_by_event_name::make_row() + + Table EVENTS_WAITS_SUMMARY_BY_INSTANCE is a 'on the fly' aggregate, + because the data is collected on the fly by (1) and stored into a buffer, + pfs_mutex.

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.

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" + +/* 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?
