René Cannaò	aaf83eec78	Finalizing the support for more session variables ... Initial support for `SET SESSION TRANSACTION READ ONLY` or `READ WRITE`. Extended `SET` parser to support also `SET SESSION TRANSACTION`. Hostgroup Manager doesn't kill backend connections in case of error 1231. `autocommit` is set at session level but also on MySQL client connection. Added several debugging entries. Several `handler_again___verify_backend_*` functions are disabled if `locked_on_hostgroup` is enabled.	7 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
