René Cannaò	7e80539c3e	More bugfixes and testing on SSL and fast_forward ... In a previous commit we fixed the fact that if more than 16KB of data was sent to Admin, SQLite3 Server or Clickhouse Server, no further data was detected thus blocking. It seems that in some circumstances data can be returned in chunks of 4KB, thus we removed the 16KB logic replacing it with multiples of 4KB.	3 years ago
René Cannaò	d836b0b032	More bugfixes and testing on SSL and fast_forward ... This commit is related to the previous one: 4c21a6d8c7 OpenSSL handles data in blocks of 16KB. If more than 16KB of data was sent to Admin, SQLite3 Server or Clickhouse Server, no further data was detected, thus blocking. Added test_ssl_fast_forward-2-t.cpp for further testing.

Javier Jaramago Fernández	c83517c406	Several improvements to RESTAPI interface #4001 ... This commit pack a couple of fixes and improvements for the RESTAPI: - Homogenization of GET/POST endpoint responses by ProxySQL. All responses should now be guaranteed to be valid JSON. - Fix JSON construction from parameters supplied to GET endpoint. - Add two new fields 'script_stdout' and 'script_stderr' to the JSON response when the target script fails to be executed. This is, when it exists with an error code other than zero. This makes the response homogeneous to when the scripts fails to produce a valid JSON output, and add extra information for debugging on client side. - Add a new debugging module 'PROXY_DEBUG_RESTAPI', to help tracing in debugging builds the requests to the endpoints.	3 years ago
Javier Jaramago Fernández	bcfc2329c5	Rework 'wexecvp' replacing legacy 'select' in favor of 'poll' #4001 ... This commit addresses several issues with 'wexecvp': - Fix invalid double call to 'close' in case fd was higher than 'FD_SETSIZE'. This could lead to the invalidation of an unrelated fd resulting in asserts, as in issue #4001 and other instabilities. - Fix previous limitations of the legacy 'select 'impl that rendered the RESTAPI unusable when ProxySQL had more then 'FD_SETSIZE' fds opened. - Other minor improvements in function logic and interface.	3 years ago
Rahim Kanji	9e218b2716	Code cleanup	3 years ago
Rahim Kanji	29677cb983	Check and remove connection from monitor connection pool if not used for long time.	3 years ago
Rahim Kanji	c552fdb111	* Added DNS cache monitoring for ProxySQL servers. ... * Added forced triggering of DNS Cache Update on MySQL Servers and ProxySQL Servers table update. * Direct DNS cache update via socket (connected peer ip) if record is not available in cache. * Used strdup instead of realloc. * DNS lookup only once for ProxySQL Cluster Nodes.	3 years ago
Javier Sánchez Parra	23cab574ac	Add new variable 'mysql-parse_failure_logs_digest' ... If the variable is 'true', ProxySQL prints the digest instead of the query when it has a parse failure.	3 years ago
Javier Sánchez Parra	e4b349cf8e	Fix unaligned memory access in OK to EOF package conversion ... Fix unaligned memory access in ok_to_eof_packet() when copying warnings and status flags from OK to EOF packages.	3 years ago
Javier Sánchez Parra	ef3478c5c2	Fix warnings and status position in EOF to OK package conversion ... If a client connects to ProxySQL not using CLIENT_DEPRECATE_EOF and it caches a resultset, when a client using CLIENT_DEPRECATE_EOF executes the same query it will get a resultset with wrong warnings and status flags. This is because warnings and status flags position must be swapped when converting an EOF packet to an OK packet. More info about warnings and status flags position in EOF and OK packets: https://dev.mysql.com/doc/dev/mysql-server/latest/page_protocol_basic_eof_packet.html https://dev.mysql.com/doc/dev/mysql-server/latest/page_protocol_basic_ok_packet.html	3 years ago
Javier Sánchez Parra	6a3a824a18	Fix sequence id in EOF to OK packet conversion #3698 ... Fix invalid resultset when using query cache and mixing clients using and not using CLIENT_DEPRECATE_EOF. If a client connects to ProxySQL not using CLIENT_DEPRECATE_EOF and it caches a resultset, when a client using CLIENT_DEPRECATE_EOF executes the same query it will get an invalid resultset and the client will disconnect. The data in the resultset is correct, but proxysql skips a sequence id thus the client assumes it is corrupted.	3 years ago

Javier Jaramago Fernández	67fac0b761	Fix 'compression' integration with 'fast_forward' sessions ... - Compression flag is now propagated from client to backend connection when the backend connection is being created for a 'fast_forward' session. In case of client trying to connect without compression, to a server configured with compression, we fallback to an uncompressed connection. - After a 'MySQL_Session' has obtained a connection for a 'fast_forward' session, i.e, the one-to-one relationship between the client and backend connection has been stablished, we completely disable the compression 'STATUS_MYSQL_CONNECTION_COMPRESSION' flag from the client 'MySQL_Connection'.	4 years ago

René Cannaò	5fb0eef19a	Fix isolation level in AWS Aurora ... If aurora_read_replica_read_committed is set, isolation level is internally reset so that it will be set again. This solves the weird behavior in AWS Aurora related to isolation level as described in https://docs.aws.amazon.com/AmazonRDS/latest/AuroraUserGuide/AuroraMySQL.Reference.html#AuroraMySQL.Reference.IsolationLevels Basically, to change isolation level you must first set aurora_read_replica_read_committed , and then isolation level	4 years ago

Because of MySQL bug https://bugs.mysql.com/bug.php?id=107875 , autocommit=0 can "create a transaction" even if SERVER_STATUS_IN_TRANS is not set. This means that a SAVEPOINT can be created in a "transaction" created with autocommit=0 but without SERVER_STATUS_IN_TRANS . This commit takes also care of scenarios when autocommit=0 was switched back to autocommit=1 when a SELECT was executed while variable mysql-enforce_autocommit_on_reads was false.

René Cannaò	5e68075edf	Cluster: Speed up processing of MySQL Query Rules ... Multiple changes: - Query_Processor stored the resultset of query rules loaded to runtime (previously this was only for query rules fast routing) - Admin returns the stored resultset (query rules and fast routing) when queries by Cluster - In khash replaced the hashing function from the built-in __ac_X31_hash_string to CityHash32 - When Cluster is used, it calls load_mysql_query_rules_to_runtime() passing the resultsets retrieved by the remote peer - Increased SQLite cache_size to ~50MB: this seems to be a very small optimization and probably it will be reverted - pull_mysql_query_rules_from_peer() uses transactions to write to mysql_query_rules_fast_routing - (important change) pull_mysql_query_rules_from_peer() verifies the checksum of MySQL Query ules before loading them to runtime	4 years ago
