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

Dirkjan Bussink	ce338bd8df	Remove hardcoded capabilities that the client uses ... These hardcoded capabilities end up being set on all backend connections ProxySQL makes. We don't want CLIENT_MULTI_RESULTS & CLIENT_PS_MULTI_RESULTS to be enabled hardcoded, but they should be dependent on the client connecting to ProxySQL. Having this mismatch meant that any connection that was not setting these flags would not be multiplexed with subsequent connections as the client of client flags would not match.	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
