Rene Cannao	700459f67b	tsdb: address AI code review feedback, fix memory safety and logic bugs ... Summary of changes: - Fixed allocator mismatches (sqlite3_free vs free) across multiple files. - Converted manual SQL construction to prepared statements for TSDB variables. - Resolved memory leaks in statistics and monitoring loops. - Fixed critical 'LOAD TSDB VARIABLES FROM CONFIG' command mismatch. - Improved command parsing robustness using string searching. - Standardized SQL LIKE patterns with escaped wildcards (\%). - Switched to data-driven variable management in ProxySQL_Statistics. - Improved web dashboard security with URL encoding and const correctness. - Clarified documentation regarding configuration lifecycle and schema names. - Updated TAP tests for better reliability and correct persistence verification.	1 week ago
Rene Cannao	b8c6b4f573	tsdb: address code review comments and improve stability ... - Refactored variable flushing to use prepared statements for safety. - Replaced brittle command parsing with robust string searching. - Extracted TSDB dashboard HTML/JS to separate source file for maintainability. - Added NULL guards for GloProxyStats in Admin and REST API. - Implemented batched metric insertions using transactions for performance. - Refactored backend probing to use non-blocking connect() with timeout. - Fixed potential integer overflows in timer calculations. - Improved error handling and fixed memory leaks in statistics reporting. - Updated TAP tests to verify UI and REST API functionality.	1 week ago

René Cannaò	d4d2298a6f	Debug logging to disk ... Introduced new schema debugdb_disk (on disk) and table debug_log . Debug entries will now go to this new table based on the value of variable admin-debug_output . If: 1) default behavior: write to stderr 2) write only to debugdb_disk.debug_log 3) 3 = 1+2 = write to stderr and to debugdb_disk.debug_log All these functionalities exist only on debug build. Table debugdb_disk.debug_log has also a column named "note" that can be used to write user notes during debugging.	3 years ago
René Cannaò	52842f6056	Build on MacOS ... Removed dependency from installed curl and openssl: now it uses statically linked ones. Updated config.guess and config.sub for cityhash and libdaemon MariaDB client connector uses statically linked libssl and installed libiconv DEBUG build uses pthread_threadid_np() instead of syscall(SYS_gettid) Fixed some variable types. Enabled the use of jemalloc also for MacOS Alias mallctl() to je_mallctl() Removed libre2.a from libproxysql.a	4 years ago
Javier Jaramago Fernández	4cd0774549	Fix 'int' overflow when computing 'next_timer_mysql_query_digest_to_disk' #3873	4 years ago
Jared Jetsel	962116f1b6	Fixed typo, memory leak, and documentation. ... * Fixed typo for variable_id in history_mysql_status_variables table definition to be INT NOT NULL as intended. * Added comments before debug ifdefs to explain their purpose * Optimized get_variable_id_for_name by performing one less search by using iterator insteaed of knows_variable_name() call. * Fixed memory leak by deleting resultset before return in lambda.	4 years ago
Jared Jetsel	910a626652	Fixed error messages ... Added new lines for the proxy_error() calls, and following similar convention as others, fixed a typo, and type conversion.	4 years ago
Jared Jetsel	d114dbe3a3	Const strings where appropriate and improved test for statistics ... Changed the get_variable_id_for_name, and knows_variable_name to use const string &. Changed immutable strings to to be const as well. Added details comment to test_admin_stats-t.cpp test. In the test code, improved documentation, set a valid interval for metrics insertion, and added the commands to set the interval. Changed the sleep time to be the inteval plus a second should be long enough to let new metrics data be added. Put additional sleep before test 2. Fixed incorrect column index usage in test 4 result set. Reformulated test 5, to check the number of records inserted after new interval is correct.	4 years ago
Jared Jetsel	0ef478e597	In debug mode, the handlers for ProxySQL_Statistics are called even if the web interface plugin is not loaded. This way the code can be tested even if the plugin is not loaded. Added new member function ProxySQL_Statistics::knows_variable_name(), which is used to check if a variable_name is in the map. This is useful to do a check before get_variable_id_for_name() in instances where it is undesirable to load or create entries in the lookup table, while keeping direct access to the map private and mutex protected. In ProxySQL_Statistics::get_variable_id_for_name, wrapped the variable_id select code in a lambda so that it could be reused instead of calling sqlite3_last_insert_rowid(), as there were some thread safety concerns which potentially could produce incorrect ids. Changed the insert to use execute() instead of execute_statement() instead, sufficient and simpler. Added error in case the function could not find, load, or generate a new id.	4 years ago
Jared Jetsel	1adaf74170	Modified ProxySQL_Statistics to have two new member functions and two new private members. These are used to map the string variable_name to an integer variable_id to improve scalability. See documentation about their usage. Updated the MySQL_Threads_Hander_sets_v2 function to load the variable_name_id_map if it is empty for initial load from the lookup table. The prepared statement binds was changed to use the int64 variable_id retreived from the map.	4 years ago
Jared Jetsel	d644f13780	Updated the SQLite history_mysql_status_variables create table statement to use variable_id instead of name for improved scalability. Added an index for the sql_status_variables table. Added lookup table create statement for history_mysql_status_variables_lookup table to refer the variable_id integer key to the variable_name string. Inserted the new table definition and execute code for the create index that were added. As the code has not yet received public release, there is no concern of keeping the previous table definition, and so the version number refers to v2.4.0.	4 years ago
