René Cannaò	d4d2298a6f	Debug logging to disk ... Introduced new schema debugdb_disk (on disk) and table debug_log . Debug entries will now go to this new table based on the value of variable admin-debug_output . If: 1) default behavior: write to stderr 2) write only to debugdb_disk.debug_log 3) 3 = 1+2 = write to stderr and to debugdb_disk.debug_log All these functionalities exist only on debug build. Table debugdb_disk.debug_log has also a column named "note" that can be used to write user notes during debugging.	3 years ago

René Cannaò	36575d273a	Several code improvements ... In Admin: - replaced a lot of flush_[...]__from_memory_to_disk() and flush_[...]__from_disk_to_memory() with a generic flush_GENERIC__from_to() - several commands like "LOAD MYSQL SERVERS FROM DISK" and similar are automatically generated for various modules (not all) and saved/map in a map load_save_disk_commands - FlushCommandWrapper() is able to map the various LOAD/SAVE from/to DISK into commands to run on SQLite	3 years ago

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

René Cannaò	9f264fcf1d	In Cluster pull_mysql_servers_from_peer() lock mysql_servers only if mysql servers tables are going to be written. ... Before this commit we were calling GloAdmin->mysql_servers_wrlock() at the beginning of the synchronization. This was not ideal as we should call GloAdmin->mysql_servers_wrlock() only if we are really going to write the tables. In other words, only if the resultsets are fetched from the remote peer, and if their checksums didn't change in the meantime.	4 years ago

René Cannaò	5bfbca7f2d	Preserve epoch when synching with ProxySQL Cluster ... On a large ProxySQL Cluster it was possible that an old configuration reaches a node (nodeA) later than a new configuration is applied to another node (nodeB). This has the side affect that nodeB will then believe that nodeA has a newer configuration, while in reality is an old configuration applied later. This commit preverves epoch, thus should avoid this problem	5 years ago
