René Cannaò	b9d155b4a5	Set variables before setting lock_hostgroup ... This commit fix the following bug: If some session variables were set by the client before proxysql turned on lock_hostgroup, these variables were not set.

René Cannaò	485d313514	Further development of firewall whitelist. ... * introduced 2 new variables: - mysql-firewall_whitelist_enabled : defines if the firewall with whitelist algorithm is enabled or not - firewall_whitelist_errormsg : error message returned to the client if an error message is not already set * Query_Processor returns firewall_whitelist_mode to the calling MySQL_Session, but the logging on error log currently happens within the Query_Processor itself * if mysql-firewall_whitelist_enabled is turned on and a user it is not found in mysql_firewall_whitelist_users , the default behavior is that query is rejected * lookup on mysql_firewall_whitelist_users happens for username@ip (specific IP) and username@'' (all IPs) . Match on network subnet is currently not implemented * implemented SAVE MYSQL FIREWALL FROM RUNTIME * fixed implementation of SAVE MYSQL FIREWALL TO DISK * runtime configuration can be viewed in runtime_mysql_firewall_whitelist_rules and runtime_mysql_firewall_whitelist_users	6 years ago
René Cannaò	c967bc179b	Several improvements to SQLite3 Server module: ... - ability to handle transactions - in OK packets and resultsets, SERVER_STATUS_IN_TRANS flag is set if a transaction is running - a persistent database file in datadir is used instead of in-memory database - database file uses WAL (Write-Ahead Logging) - WAL journal size is set to 64MB - monitor user can always login to SQLite3 Server - in case of database lock within a transaction, an error is immediately returned to client	6 years ago

René Cannaò	2fec51c0a9	A lot of changes to make query digest map faster ... Extended SQLite3_result to support a mutex for concurrent rows insert. Extensively rewritten get_query_digests() and get_query_digests_reset() to support multiple threads, and concurrently generate a resultset. Function get_query_digests_reset() defer the deletion of objects from query digest map after generating the resultset for Admin. This drastically reduce the amount of time that query digest map is locked. Rewritten get_query_digests_total_size() to make it multi-threaded. Added 3 new functions for purging: - purge_query_digests() : wrapper - purge_query_digests_sync() : synchronous purge of query digest map, either single-threaded or multi-threaded - purge_query_digests_async() : asynchronous purge of query digest map, single-threaded only If table `stats_mysql_query_digest_reset` is queried but not `stats_mysql_query_digest`, only the first one is populated. If table `stats_mysql_query_digest_reset` is queried and also `stats_mysql_query_digest`, the second one is populated as a copy from the first. Implemented new SQL `TRUNCATE [TABLE]` for `[stats.]stats_mysql_query_digest[_reset]`: this will purge the query digest map as fast as possible without creating any table in SQLite. For testing/benchmark: - modified ProxySQL_Test___GenerateRandomQueryInDigestTable() to generate more random data and randomly switch `mysql_thread___query_digests_normalize_digest_text` Extended command `PROXYSQLTEST` with the following tests: - 1 : generates entries in digest map - 2 : gets all the entries from the digest map, but without writing to DB, with multiple threads - 3 : gets all the entries from the digest map and reset, but without writing to DB, with multiple threads - 4 : purges the digest map, synchronously, in single thread - 5 : purges the digest map, synchronously, in multiple threads - 6 : purges the digest map, asynchronously, in single thread (this seems the faster) Replaced some sprintf() with new function my_itoa() . Modified class QP_query_digest_stats() to include username, schemaname and client_address if no longer than 24 bytes. This makes storage requirement for QP_query_digest_stats() bigger, but reduces a lot of calls to memory management. Modified QP_query_digest_stats::get_row() to drastically reduce the number of malloc/free and string copy. Overall, this commit has the following effects: - it increases the memory usage for query digest map. On test workload, this results in 10% more memory usage - drastically reduces the calls to memory management - populating `stats_mysql_query_digest_reset` is 3 times faster - the amount of time in which query digest map is locked is reduced by 95%	7 years ago

SET statements that cannot be parsed correctly disable both multiplexing AND routing.

Default is 0 - added global variable mysql-eventslog_format : default is 1 (legacy format). A value of 2 enables logging in JSON format. Issue #871 Changing value at runtime causes the current file to be closed and a new one created - fixed logging for prepared statements: till 2.0.5 only some percentage of prepared statements was correctly logged Extended tables stats_mysql_query_digest and stats_mysql_query_digest_reset to also include sum_rows_affected and sum_rows_sent Extended `eventslog_reader_sample.cpp` to support the new enhancements	7 years ago

René Cannaò	7b3757a273	Remember if the current connection has an unknown transaction status ... The fix for bug #1038 was to not return a connection to the connection pool if it has an error. Although this is correct, it also has the side effect that connections coming from connection pool and failing during the first query because the connection was already broken, would be considered as possibly to run a transaction. That is incorrect. Now at connection level it is tracked if the transaction status is known or not.	8 years ago
