Javier Jaramago Fernández	8bc60ed283	Fix worker threads stalling race condition on RESUME command ... During a RESUME operation, if a 'MySQL_Thread' is bootstrapping listeners (in `MySQL_Thread::run_BootstrapListener`) and detect that `MySQL_Threads_Handler::bootstrapping_listeners` is 'false', the thread prematurely shuts down its own bootstrapping flag from 'mypolls' (`ProxySQL_Poll::bootstrapping_listeners`). Since this thread wont ever bootstrap its corresponding listening sockets, the other working threads will be stalled waiting on it, eventually triggering the watchdog and crashing the instance. Since the bootstrapping operation is sequential, it's expected that all the threads but the one starting their listening sockets are in an active wait. A sensible delay has been introduced to reduce the overhead of such wait.	1 year ago

René Cannaò	ce4394e1c3	Merge pull request #4744 from sysown/v3.0_issue_4707_threshold_resultset_size ... Fix Overflow in *-threshold_resultset_size during Multiplication - v3.0	1 year ago
Rahim Kanji	bd6674c383	* Introduced a 5% jitter to cache_ttl to increase the likelihood of distributing DNS resolution across multiple intervals, reducing the chance of simultaneous expiry times. ... * Added a small delay after queuing DNS records, allowing DNS resolver thread time to process as many hostnames as possible before assessing the need for additional helper threads. This helps prevent 'DNS resolver queue too big' warnings in the logs.	1 year ago

Javier Jaramago Fernández	100630fba5	Second iteration on PostgreSQL monitoring POC ... This commit packs multiple fixes/improvements: - Added READONLY support for PostgreSQL. - Major rework for queries and statements used on monitoring checks: + Checks/Actions rewrote for single instance checks. + Reuse of prepared statements instance of re-preparation. - Fixed missing error handling in connection creation state machine. - Fixed connection rotation in connection pool (now FIFO). - Added support for configurable batching in scheduler thread, via '*_interval_window' variables. These variables allows to define the burstiness of the scheduling within the processing interval. - Added new config variable 'pgsql-monitor_dbname'. Allows to control which 'db' will be target by monitoring connections. - Several fixes for 'poll' timeout computation for worker threads. - Fixed edge cases for current interval detection. - Reduced deviation in scheduling intervals computation. - Refactored and simplified connection event handling. - Improved error messages for monitoring actions. - Replaced several invalid uses of 'mysql_thread___monitor_*' in favor or new 'mysql_thread___monitor_*' variables. - Honor '-M' argument for disabling monitoring support.	1 year ago

Rahim Kanji	720441af20	Refactored and Optimized Query Cache with PgSQL Support ... * Added Query Cache Support for PgSQL: * Introduced new variables for PgSQL Query Cache management: * pgsql-query_cache_size_MB * pgsql-query_cache_soft_ttl_pct * pgsql-query_cache_stores_empty_result * pgsql-query_cache_handle_warnings (not yet utilized) * Overwriting Transaction Status: * Sending current transaction state to the client when a result is returned from the query cache. * This currently does not differentiate between normal and error transaction states—both are treated as active transaction states. * Cache Lifetime Management: Replaced manual reference counting with std::shared_ptr to efficiently manage the lifecycle of cache entries, ensuring proper memory deallocation and reducing complexity. * Unified Purging Logic: Refactored the query cache purging logic to use a single thread for both MySQL and PgSQL cache entries. * Code Cleanup: Removed unnecessary methods and data members to streamline the codebase and improve maintainability. * Performance Optimization: Improved memory management, reducing memory footprint and enhancing performance.	2 years ago
