René Cannaò	8b119f6ec5	A lot of code clean up	11 years ago
René Cannaò	125114b0d5	Work for facilitate debug in MySQL Thread (issue #198) ... In order to facilitate the reuse of code in Standard_ProxySQL_Admin.cpp : - moved remove_spaces() from Standard_ProxySQL_Admin.cpp to gen_utils.cpp - moved Standard_ProxySQL_Admin::SQLite3_to_MySQL() to MySQL_Session::SQLite3_to_MySQL() Moved few macros from Standard_Query_Processor.cpp to proxysql_macros.h Added functions: - MySQL_Session::SQL3_Session_status() - MySQL_Session::handler___status_WAITING_CLIENT_DATA___STATE_SLEEP___MYSQL_COM_QUERY_debug() - Standard_MySQL_Thread::SQL3_Thread_status() - MySQL_Threads_Handler::SQL3_Threads_status() (not completed) Modified class Query_Info to copy queries : this can be a small performance penalty, but can improve functionalities Added mysql commands: - DBG SESSION STATUS - DBG THREAD STATUS - DBG THREADS STATUS Added variable MySQL_Thread::thread_mutex , a mutex to protect the thread: this will be used to implement access to MySQL Thread via Admin MySQL_Thread now have a new per thread variable updated via Admin Interface : - mysql_thread___session_debug ProxySQL_Poll now counts number of poll() in variable "loops" If mysql_thread___session_debug is enabled and a query starts with "dbg " it is interpreted as a command for proxysql. In Standard_ProxySQL_Admin added a variable admin_mutex to protect the update of statistics. Fixed minor bugs.	11 years ago

Jesmar Cannaò	d4f9c49e1b	Fix Issue #182 ... Prevent loading modules compiled for a different version	11 years ago
René Cannaò	df0b81ddea	More improvements on Connection Pool ... For issue #187: Introduced the follow functions: - MySQL_Session::handler___status_CHANGING_USER_SERVER() - MySQL_Session::handler___client_DSS_QUERY_SENT___send_CHANGE_USER_to_backend - MySQL_Protocol::generate_COM_CHANGE_USER() Modified MySQL_Session::handler___status_CHANGING_SCHEMA() to return a boolean to handle failures Connections where INIT_DB or COM_CHANGE_USER fails are not reusable Added session_statuses CHANGING_USER_SERVER and CHANGING_USER_CLIENT (currently not used, but needed for issue #187) For issue #188: Added variable MySQL_Connection_userinfo::hash : this is compared into MySQL_Session Added function MySQL_Connection_userinfo::compute_hash() to automatically compute MySQL_Connection_userinfo::hash when a variable is changed hash is compute with SpookyHash::Hash64() Fixed bug #189: removed an parameters incorrectly passed to fprintf	11 years ago
Jesmar Cannaò	3a9fe080ee	FIX ISSUE #174:: Print "DEBUG" in print_version() if compiled with DEBUG option : all modules	11 years ago
René Cannaò	44f433c260	Replaced MySQL_Session_userinfo with MySQL_Connection_userinfo ... Due the change in Connection Pool, user information need to be stored at Connection level and not at Session level	11 years ago
René Cannaò	13eb687335	More work on issue #168 ... Implemented new class Query_Info used in MySQL_Session Added MYSQL_COM_QUERY_command MYSQL_COM_QUERY_COMMIT Added virtual function Query_Processor::query_parser_update_counters() curtime moved from local variable in Standard_MySQL_Thread::run() to public variable in MySQL_Thread , so accessible by other classes Extended stats_mysql_commands_counters from 2 columns to 15 columns!! It nows have betters statistics on timing and distribution Added command MYSQL_COM_QUERY___NONE as a marker . It also have the special meaning that Query_Info is not a query. commands_counters is now an array of pointers to Command_Counter objects MySQL_Data_Stream::read_from_net() updates mypolls->last_recv[] with curtime if mypolls is active (MySQL_Thread) MySQL_Data_Stream::write_to_net() updates mypolls->last_sent[] with curtime if mypolls is active (MySQL_Thread) For MySQL queries (_MYSQL_COM_QUERY) queries statistics are updated via CurrentQuery, an instance of Query_Info	11 years ago
René Cannaò	a85bc44715	Implemented table stats_mysql_commands_counters : issue #168 ... Implemented get_stats_commands_counters() in Query_Processor Implemented stats___mysql_commands_counters() in ProxySQL_Admin Added table mysql_commands_counters Added MYSQL_COM_QUERY_SHOW_TABLE_STATUS in MYSQL_COM_QUERY_command Standard_Query_Processor has the commands description in commands_counters_desc Introduced per thread storage variable _thr_commands_counters query_parser_command_type() is now a wrapper to __query_parser_command_type() so to update counters based on its return value Bug fixed: Added transactions in Standard_ProxySQL_Admin::stats___mysql_query_rules() Added SHOW command in libinjection	11 years ago
René Cannaò	848b15f149	More work on parser : Issue #158 ... Implemented query_parser_command_type() to at least recognize queries from sysbench Currently commands supported: - ALTER [ONLINE | OFFLINE] [IGNORE] TABLE - ANALYZE [NO_WRITE_TO_BINLOG | LOCAL] TABLE - BEGIN - COMMIT - DELETE - INSERT - SELECT (not for update) - SET - UPDATE Small change on libinjection : Issue 152 Added COMMIT	11 years ago
René Cannaò	5f179eca36	Started working on query parsing. Issues #158 and #152 ... Per issue #158: - Created 4 new functions in class Query_Processor. - See doc/internal/query_parser.txt Per issue #152: - Patched deps/libinjection/Makefile to compile with -fPIC - Standard_MySQL_Thread is linked against libinjection	11 years ago
René Cannaò	62e2e78736	Issue #146 ... - created Query_Processor::update_query_processor_stats() - every mysql_thread___poll_timeout millisecond MySQL_Threads call GloQPro->update_query_processor_stats() to update global statistics update_query_processor_stats can be extended to load more type of queries	11 years ago
René Cannaò	322a4f021f	Enhancement on Query Processor and draft statistics interface ... - changed hits from uint64_t to int; - QP_rule_t has a pointer to its parent : this is done to speed up lookup - implemented get_current_query_rules() to execute SAVE MYSQL QUERY RULES FROM RUNTIME (issue #93) - implemented get_stats_query_rules() to save statistics on stats_mysql_query_rules (issue #139) - created 2 new classes to easily process statistics in Query Processor : QP_rule_text and QP_rule_text_hitsonly - extended classes SQLite3_row and SQLite3_result - every __admin_refresh_interval milliseconds Admin refreshes statistics - defined table stats_mysql_query_rules - deprecated __attach_configdb_to_admindb() , replaced with __attach_db_to_admindb (used in issue #142) - to admindb are now attached both configdb and statsdb (issue #142) - drafted a way to update hits on Query Processor . This method will go away when issue #146 will be implemented - fixed crashing bug in issue #145	11 years ago
